Abstract A project of Quaternary geology mapping and regional humus andtill samplingwas undertakenover theeastern part of the Shebandowan greenstone belt during the 1998 field season. Quaternary mapping helped to characterize the surficial materials present within the study area and to reconstruct the ice flow history associated with these deposits. This information provided a framework by which the regional materials compositional datasets could be interpreted. The regional sampling program provided information on the background concentrations of various elements in humus and till as well as on the number and character of gold grains and base metal indicator minerals present in till. Widespread evidence for multiple ice flow events is present within the study area. The entire region was initially affected by a south-southwesterly flowing ice sheet that resulted in the deposition of a silty sandy till, of local provenance, on the bedrock surface. Following the retreat of northern ice from the region, a late stage surge event resulted in ice reoccupying a portion of the study area. A lobe of “Superior” ice flowed northward and westward out of the Lake Superior basin into the lowland now occupied by the Whitefish and Kaministikwia rivers in the southeastern corner of the study area. Northern ice also advanced into the extreme northeastern corner of the study area reoccupying the Dog Lake basin. Deposits of glaciolacustrine silt and clay and fine-textured till were laid down in front of and beneath the advancing Superior and northern ice lobes concealing much of the bedrock surface and older, northern drift. Distinc- tive red glaciolacustrine clays, associated with Glacial Lake Kaministikwia, accumulated in low-lying areas beyond the limits of the Superior and northern lobes. Till sampling programs within these areas of thick overburden cover require the use of alternative exploration methods such as overburden drilling. The till and humus sampling programs have clearly defined a number of precious and base metal exploration targets within the study area. Higher density follow-up surveys of till sampling are recommended for these areas to more precisely define potential source rocks. Superior and northern till populations were treated separately as they have compositionally distinct signatures. Superior lobe till reflects local bedrock sources only in areas where it rests directly on bedrock. The patterns depicted by the humus dataset generally support the till data although there are situations where they differ. The significance of these differ- ences requires further work. Humus collected along the Highway 11/17 corridor appears to be contami- nated with wind blown Ni-Cu concentrate dating back to the time when it was hauled in dump trucks from the Shebandowan mine to a rail siding at Sistonens Corners. The discovery of numerous samples of mineralized float throughout the map area also indicates the potential for additional mineral discoveries. Boul- der tracing appears to be a viable exploration tool within the study area. A complete digital dataset, consisting of locational information, gold grain counts, selected oxide/sulphide mineral counts, INAA and ICP-OES geochemical data of humus, till and float boulders is being released in conjunction with this report as Miscellaneous Release-Data 44.

Introduction Increased exploration activity north and west of Thunder Bay has been attributed to the recent recognition of a new gold belt traversing the eastern portion of the Shebandowan greenstone belt (Lavigne and Scott 1994). This 75 km long by 6 km wide gold belt, informally referred to as the “Matawin gold belt”, has yielded over 50 new gold occurences within the last 15 years. Exploration activity prior to this period focussed primarily on the belt’s iron ore potential. The recent discovery of “high-grade”, base metal float in northeastern Aldina Township also resulted in much of the southeastern portion of the belt being staked and evaluated for its base and precious metal potential (Lavigne and Scott 1997). Much of the exploration activity within the Shebandowan greenstone belt has currently subsided, large- ly in response to the depressed prices of precious and base metals and the inability of junior mining compa- nies to raise funds for exploration. In addition, after almost 3 decades of operation, the INCO Limited She- bandowan nickel mine was decommisioned during the second quarter of 1998. In response to this recent decline in mining and exploration activity within the belt, the Ontario Geo- logical Survey initiated a 2 year program of Quaternary geology and drift geochemistry to further evaluate the mineral resource potential of the Shebandowan belt. This was accomplished by detailed (1:50 000 scale) Quaternary geology mapping and regional humus and c-horizon till sampling. Quaternary mapping was undertaken to document the distribution and character of the various Quaternary deposits within the study area and to reconstruct the ice flow history associated with these deposits. This information is essen- tial to better understand how the various surficial materials can be utilized for mineral exploration programs. During the 1998 field season, Quaternary mapping and regional humus and c-horizon till sampling were conducted within the area covered by the Sunshine (52A/12) and Kakabeka Falls (52A/5) 1:50 000 scale National Topographic System (NTS) map sheets (Figure 1). Detailed, property-scale soil sampling was also conducted over and adjacent to the Bylund gold occurrence which is situated along Highway 11/17 at the west end of the Dawson Road Lots (Figure 1). This orientation survey was undertaken to characterize glacial dispersal, in terms of magnitude, shape and composition, from a known gold source. This information will be applied to the interpretation of the regional materials dataset. Quaternary mapping and regional drift geochemistry of the Shebandowan (52B/9), Burchell Lake (52B/10) and northern portion of the Mowe Lake (52B/7) 1:50 000 scale NTS map areas to the west will be undertaken during the 1999 field season (Figure 1).

Bedrock Geology A comprehensive summary of the bedrock geology of the study area is contained in papers by Sutcliffe (1991), Williams (1991) and Williams et al. (1991) as well as in numerous Ontario Geological Survey maps and reports. The study area contains 3 distinct bedrock domains (Figure 2). The centrally-located Wawa Subprovince, within which the Shebandowan greenstone belt occurs, is fault-bounded to the north by metasedimentary and felsic intrusive rocks of the Quetico Subprovince and unconformably overlain to the south by Paleoproterozoic metasedimentary rocks of the Animikie Group (Gunflint and Rove formations). Metasedimentary rocks of the Quetico Subprovince consist primarily of turbiditic wackes, arkoses and quartz arenites and their associated paragneisses and migmatites. Post- to syndepositional felsic plutons consisting of feldspar-megacrystic granite, granodiorite to tonalite and monzonite comprise a notable proportion of this domain. Narrow, elongate lenses of tholeiitic, mafic metavolcanic rocks and associated gabbroic rocks occur locally (Brown 1995). Metasedimentary rocks of the Gunflint and Rove formations (Animikie Group) were deposited within a large basin that extends into Minnesota, Wisconsin and Michigan (Sutcliffe 1991). The Gunflint Formation contains a basal unit of conglomerates that rest unconformably on the Archean basement and are overlain by interbedded argillites, argillite tuffs, cherts, algal cherts, jasper, carbonates, ferruginous carbonates, he- matite, magnetite taconite and silicate taconite. The overlying Rove Formation consists of black, locally pyritic shales and grades upward into interbedded black shale and arkosic greywackes. Mesoproterozoic “Logan” diabase sills intrude the Rove Formation and form the resistant cap rocks of large mesas in the

1 2 3 southern part of the map area. Silver mineralization occurs locally along normal faults that intersect the contact between Rove Formation shales and Logan diabase sills. Notable silver deposits occur in the southeastern corner of the Kakabeka Falls NTS map area, in the vicinity of Badger and Beaver mountains (Creswel or Rabbit Mountain group of deposits) and Silver Mountain. Accessory minerals in these deposits include: acanthite; pyrite; sphalerite; marcasite; galena; calcite; quartz; barite; and fluorite (Franklin et al. 1986). Additional information on the character of these deposits is contained in the same publication. Supracrustal rocks of the Shebandowan greenstone belt can be subdivided into 2 contrasting packages of metavolcanic and metasedimentary rocks: 1) an older suite of mafic to felsic metavolcanic rocks defined by the Burchell and Greenwater assemblages; and 2) a younger suite of metasedimentary and metavolcanic rocks referred to as the Shebandowan assemblage. The Greenwater and Burchell assemblages each consist of 3 oppositely-facing, bimodal metavolcanic cycles typically consisting of a lower sequence of tholeiitic basalts and an upper sequence of calc-alkalic andesite, dacite and rhyolite (Williams et al. 1991; Rogers and Berger 1995). The younger, Shebandowan assemblage unconformably overlies (i.e., fault contact) and intrudes the Greenwater and Burchell assemblages. It consists of alkalic metavolcanic and intrusive rocks (tuff, breccia, syenite, lamprophyre, quartz and feldspar porphyry, granodiorite and diorite) as well as metasedimentary rocks (arkoses, wackes, conglomerates and oxide-facies iron formation) (Schnieders et al. 1998). This assemblage is interpreted as representing an intracratonic basin assemblage similar to the Ti- miskaming assemblage of the Abitibi subprovince. Most gold occurences in the eastern portion of the Shebandowan greenstone belt display a close spatial association with rocks of the Shebandowan assemblage. The style of gold mineralization is not unlike that which occurs in such prolific mining camps as Timmins and Kirkland Lake. Gold mineralization is commonly associated with both large scale and subsidiary structures and structurally-controlled intrusions. Mineralization occurs in sheeted and en echelon quartz veins, stockwork zones and vein breccias as well as in stocks, dikes and sills of felsic to mafic composition. Gold is also commonly associated with: sulphide- rich, quartz-veined replacement zones in oxide facies iron formation; silica-flooded, hydrothermally-altered zones; and iron-carbonate and pyrite-rich zones commonly associated with shear and permeable zones. Associated alteration and accessory minerals include: iron carbonate; silica; potassic feldspar; sericite; he- matite; chlorite; calcite; pyrite; arsenopyrite; tourmaline; and green mica (Schnieders et al. 1998). Notable exploration programs within the current study area are highlighted in the last 5 annual volumes of the Resi- dent Geologist’s Report of Activities. Glacial Geology The study area is characterized by several contrasting physiographic regions, each defined by a unique suite of overburden conditions. Bedrock-dominated uplands are situated in the northwest corner of the Sunshine NTS map area and the northwest and southeast corners of the Kakabeka Falls NTS map area. Aside from local accumulations of thick drift in morainic belts and narrow, structurally-controlled depressions, these uplands are essentially bedrock-dominated terrains. Thicker deposits of till and/or glaciofluvial and glaciolacustrine sediments occur within 2 isolated ba- sins (Figure 3). The northern basin, here referred to as the “Kaministikwia basin”, occupies the valleys of the Oskondaga, Matawin, Shebandowan and Kaministikwia rivers. The southern basin is centred on the valleys of the Whitefish and Kaministikwia rivers. In the northern basin, thick deposits (several tens of metres) of glaciofluvial and glaciolacustrine sediments drape a rugged Archean bedrock surface producing a gently rolling landscape with sporadic bedrock outcrops. The low relief observed within the southern basin is a reflection of not only the flat-lying Proterozoic sediments that underlie the region, but the extremely thick glaciolacustrine deposits that have infilled deep valleys along the Whitefish and Kaministik- wia rivers. Overburden thicknesses along these valleys exceed 60 m in places. The erosional and depositional features preserved within the study area record a complex history of ice flow events associated with the Wisconsinan glaciation (Figure 4). The entire study area was initially affected by southward flowing “Patrician” ice. Striae associated with this event range between 170 and 220 Az. In the southern half of the Sunshine map area, there is widespread evidence for an older ice flow event towards 160 Az. The age and significance of this event is not known. Pauses in the general retreat of the “Patrician” ice lobe resulted in the formation of large, arcuate, reces- sional moraines in northwestern Ontario. The Brule Creek Moraine, which traverses Aldina and Marks

4 5 6 townships adjacent to the Boreal Road, represents one of these stillstand positions (Figure 4). The moraine, which reaches widths of several kilometres in places, is defined by a discontinuous belt of morainic ridges and associated ice-contact stratified deposits. Zoltai (1965) correlates this feature with the Eagle- Finlayson Moraine to the west. The eastern extension of the Brule Creek Moraine beyond Marks Township has been obscured by a younger glacial advance (Figure 4). A second major moraine of northern affinity (Dog Lake Moraine) is situated in the northeastern corner of the Sunshine map area in the vicinity of Dog Lake (Figure 4). Unlike the Brule Creek Moraine, this moraine was constructed following a minor readvance of the “Patrician” ice lobe. Glaciolacustrine sediments underlying till north of the moraine support a readvance. In the vicinity of Dog Lake, the moraine is fronted by a lobate, flat-topped, glaciofluvial plain believed to be deltaic in origin. The elevation of this plain (460 m asl) defines the level of Glacial Lake Kaministikwia, a large glacial lake which occupied the Kaministik- wia basin. Distinctive red clays, associated with this glacial lake can be found throughout the basin up to, but not above, this elevation. Glacial Lake Kaministikwia was topographically-supported on its southern flanks by the large upland in the northwest corner of the Kakabeka Falls area (Figure 3) as well as by the large, northeast-trending Marks moraine that diagonally bisects the map area (Figure 4). This moraine is correlative with the Dog Lake Moraine and represents the terminal position of a lobe of ice originating from the Lake Superior basin that flowed northwestward and westward into the Whitefish-Kaministikwia lowland. Striae associated with this advance range from 340 Az in the northeast to 240 Az in the southwest attesting to the lobate nature of the Superior lobe. This advance is correlated with the Marquette stadial, a late-glacial surge event that resulted in much of the Superior basin being reoccupied by glacial ice about 9.9 ka BP. With the exception of the northeast corner of the Kakabeka Falls area, the Superior lobe advanced into a glacial lake, referred to as “Glacial Lake O’Connor” (Zoltai 1963). Numerous sections along the Whitefish River expose thick sequences of glaciolacustrine rhythmites beneath a fine-textured Superior lobe till. Shorelines of this glacial lake have not been identified. Till of northern (Patrician) provenance has been observed throughout the entire study area. On Arch- ean terrane, beyond the limits of the Superior lobe, the till has a silty sand texture with low to moderate stone-content. Unoxidized till generally has an olive-grey to buff-grey colour. The till often contains a high proportion of clasts that are locally-derived. Faceted and striated clasts within the till indicate deposition by ice flowing towards the south-southwest. Many exposures of this northern till contain remnant clasts of Sibley Group metasediments. These distinctive, reddish-coloured siltstones occur on the Sibley Peninsula and presumably, beneath Lake Superior, 75 km east and southeast of the study area (Figure 1). Their occurrence may indicate an older ice flow event out of the Lake Superior basin, the debris of which has been recycled by northern ice. Alternatively, their occurrence may indicate the presence of, as yet undiscovered, outliers of Sibley Group metasedimentary rocks north of the study area. The till of northern provenance is buried beneath variable thicknesses of glaciolacustrine deposits and Superior lobe till within the Whitefish-Kaministikwia lowland. The Superior lobe till matrix is generally of a sandy silt to clayey silt texture, owing its fineness to the underlying shales and argillites of the Rove and Gunflint formations. Stony till, of presumed northern provenance, exposed at water level along White- wood Creek in east-central O’Connor Township, contains abundant striated and faceted boulders indicating ice flow toward the southwest. Superior Lobe till is easily recognized by its fine-texture and high proportion of Animikie Group metasedimentary clasts in the pebble fraction. Even in areas underlain by Archean terrane, as occur in the northeast corner of the Kakabeka Falls area, Superior lobe till contains only a small proportion of the underlying rock types in the pebble fraction. This has important implications for programs of mineral exploration utilizing till as a sample medium. The colour of the unweathered till ranges from dark grey, to brown to reddish-brown. Sections of till, containing layers with all 3 colours have been observed in Oliver and Gillies townships and probably reflect the melting out of debris bands derived from different bedrock sources. Superior lobe till also varies markedly in texture. In Oliver Township, near the community of Murillo, Superior lobe till is silty and charged with shales of the Gunflint Formation. The till in this region is fluted and has been observed to reach thicknesses of 7 to 8 m. Similarly, to the south in Scoble and Gil- lies townships, Superior Lobe till is silty and charged with clasts of Rove Formation shale and Logan diabase. Along the axis of the Whitefish River, the till is silty to clayey and contains less than 5% clasts.

7 This is primarily due to the thick deposits of glaciolacustrine silts and clays that were overridden and incor- porated into the basal debris layers of the ice.

Sample Collection and Processing A total of 219 humus and 288 c-horizon till samples, the locations of which are listed in Appendix A and illustrated in Figure 5 (back pocket), were collected as part of the regional sampling program. Most samples were collected from the Shebandowan greenstone belt (Wawa subprovince). Sampling density within this area is approximately 1 sample per 3 km2. Sample distribution is erratic in places, limited by access as well as the nature of the surficial deposits within various areas. Samples were collected at a much lower density over the southern margin of the Quetico subprovince as well as over areas underlain by Archean felsic intrusive rocks and Proterozoic metasedimentary rocks. Samples were collected primarily within areas accessible by roads and bush trails. A short, helicopter- assisted sampling program was undertaken to obtain samples from less accessible areas and to fill in the regional sampling grid. Till was collected primarily from shallow (~1 m deep), hand-dug test pits, road- cuts, trench exposures and small borrow pits. Samples were collected from the till-bedrock interface where possible, or from as deep as possible in areas of thick till. Samples were screened in the field to remove the +5 mm fraction; this fraction was saved for lithologic determinations. At each sample site, 2 samples of c-horizon till were collected for analysis. A 10 kg sample was collected for heavy mineral concentration and subsequent gold grain, kimberlite indicator mineral (KIM) and metamorphic/magmatic massive sulphide indicator mineral (MMSIMR)* determinations. Heavy minerals were separated from the -2 mm fraction of these samples by wet gravity tabling, producing a “table concentrate”, then further concentrated to >3.2 S.G. using density-dependent settling in methylene iodide. Magnetic minerals were removed from the methylene iodide heavy mineral concentrate (HMC) using an automagnet. At the tabling stage, a preliminary count of gold grains, including size and shape determinations was undertaken. The gold grain content of the table concentrates was further refined using a secondary panning procedure to obtain more exact grain counts. Only samples containing greater than 10 gold grains at the tabling stage were panned. The size and shape of the panned gold grains were recorded before they were returned to the table concentrate. Information on the total numbers of visible gold grains and their respective shapes is contained in Appendix B. A detailed account of the sizes and numbers of gold grains recovered from the heavy mineral concentrates is provided in MRD 44 (Bajc 1999) which is being released in conjunction with this Open File Report. One hundred and eighty-three of the 289 till samples collected were analyzed for KIMs and MMSIMs. Appendix C summarizes the numbers of pyrite, chalcopyrite and chromite grains recovered as part of this process. A second 2 to 3 kg sample of screened c-horizon till was also collected for -63 micron fraction geochemical determinations. A 30 g split of the -63 micron (silt and clay) size fraction of this till matrix was sent for instrumental neutron activation analysis (INAA). The resulting geochemical dataset includes data for 35 elements. Appendix D contains the gold, arsenic and antimony data derived by the INAA method. A second split was sent for geochemical determinations by ICP-OES following a standard aqua regia digestion. The base metal results of these analyses are presented in Appendix D as well. Humus samples were collected from all undisturbed sample sites for geochemical determinations. Hu- mus samples were not collected from areas of agricultural activity nor from areas affected by fire. A 15 g split of the –177 ←m size fraction of the humus was taken for INAA analysis and a second smaller split for ICP-OES analysis following a standard aqua regia digestion. Appendix E contains the gold, arsenic and antimony data derived by the INAA method and the base metal data derived by ICP-OES (aqua regia). The complete digital, INAA and ICP-OES geochemical datasets for both humus and –63 ←m fraction c-horizon till are contained in MRD 44 (Bajc 1999).

8 Results PROPERTY SCALE SOIL SAMPLING SURVEY: BYLUND OCCURRENCE High density, property-scale soil sampling was undertaken over and adjacent to the Bylund Au occurrence at the west end of Dawson Road Lots. Fifty-three b-horizon soil samples were collected at 100 m centres on 6 grid lines spaced 100 m apart. The property is characterized as a bedrock-dominated upland with local accumulations of drift (till and stratified deposits) in low-lying areas. Most soils are developed in till, however, a small proportion have stratified sands and pebbly sands as their parent material. These samples were included in the geochemical dataset since most of them were derived from the washing and sorting of the underlying till. Soil samples were not collected from a poorly drained wetland that occurs along the west-central edge of the property. The sample grid is oriented at 150 Az and extends approximately 500 m south of the mineralized zone into unaltered Keewatin mafic metavolcanics. The silt and clay fraction of the soil samples were extracted and geochemically analyzed by instrumental neutron activation analysis and ICP-OES (aqua regia digestion). Mineralization at the Bylund occurrence is contained within a 125 m wide, east-trending zone of carbonate-altered, mafic to ultramafic metavolcanic rocks transected by a stockwork of northeast-trending quartz-carbonate veins (Schnieders et al. 1998). Finely disseminated arsenopyrite is commonly associated with mineralization. The auriferous deformation zone occurs at or near the Timiskaming/Keewatin unconformity. Channel sampling over the main Bylund occurrence has returned values of up to 4.1 g/t Au over 14 m. Outcrops exposed in trenches situated both east and west of the main showing have returned values typically in the range of 1 to 2 g/t Au over several metres. Notable intersections include a 0.54 m section, just west of the main showing, assaying 123 g/t Au (C. Bishop, Freewest Resources, personal communication, 1998). Contoured plots of Au and As content derived by neutron activation analysis are presented in Figure 6. Other elements did not show a close spatial association with mineralization. The patterns depicted by Au and As clearly delineate the position of mineralization with little or no evidence for down-ice dispersal beyond a few hundred metres. Similar scales of glacial dispersal have been previously documented at the Matachewan Consolidated Mine in northeastern Ontario (Bajc 1997) as well as at numerous other gold properties within the province. Gold values quickly decline to below detection limit (<2 ppb) within 100 to 200 metres down-ice (south-southwest) from the Bylund occurrence. Arsenic values display a slightly more diffuse pattern. Elevated Au and As values along L1W and L2W, immediately west of the documented Au zones suggests a possible westerly extension of mineralization. A sample on L1W that returned a gold value of 1280 ppb and an As value of 88.4 ppm was collected from the fringes of a poorly drained wetland and contained significant amounts of organic matter. This anomaly may have been produced by hydromorphic dispersion from mineralized till and rock on the upland to the north. A similar anomalous Au and As response was obtained, however, from an upland soil 100 metres to the east. These 2 anomalies may suggest a second auriferous structure is present to the south; this warrants further investigation. A strong Au and As anomaly along the central portions of lines 2E and 3E suggest the potential for another, as yet undiscovered, zone of mineralization. Several conclusions and recommendations can be drawn from the Bylund soil sampling orientation survey. 1. Soil geochemistry is a viable exploration tool for shear-hosted gold in the eastern portion of the Shebandowan greenstone belt. The technique is best suited to upland properties with thin till cover and abundant outcrop. 2. A sample spacing of 100 m staggered on adjacent lines appears to be sufficient for the delineation of potential mineralized zones. 3. Gold and arsenic appear to be the elements best suited for target delineation at the Bylund occurrence. Neutron activation analysis of the silt and clay fraction (-63←m) of soil provides excellent contrast between background and anomalies. 4. There is very little evidence in support of down-ice dispersal of gold greater than 100 to 200 m from mineralization. Ultra-high density sampling (i.e. 20 to 25 m spacing) would be required to more clearly define glacial dispersal patterns.

9 10 REGIONAL SAMPLING SURVEYS Gold Grain Data The presence of significant numbers of gold grains in the heavy mineral fraction of till is of interest in exploration because it can be a direct indication of gold mineralization. Where several adjacent, clustered or structurally aligned (i.e. along a fault zone) till samples yield gold grain counts exceeding the regional background value, it is likely that the source is nearby in the “up-ice” direction. High counts of visible gold are particularly significant when they occur in till samples taken directly above bedrock. Because of the low sampling density associated with this survey, single sample anomalies warrant follow-up work as well, especially if the grains show few signs of extended mechanical transport. The shape and morphology of the gold grains may be used to either characterize their transport history (Averill 1988; DiLabio 1990) or to provide insights into the style of gold mineralization. This is accomplished by assigning the grains to 1 of 3 categories based on appearance. Grains classified as pristine occur as angular wires, rods and delicate leaves that probably formed as fracture fillings, and as grains displaying primary surface textures such as crystal faces or grain molds. The transport history of grains assigned to this class may be interpreted in 2 ways. Firstly, the grains may have been eroded from a bedrock source and mechanically transported to the depositional site with little or no modification of their surface textures. Under these circumstances, the transport distance is generally short. Large numbers of pristine grains in till may also be produced by the in situ weathering of transported sulphide grains containing fine, particulate gold. In this case, little information is gained on the transport history of the gold, however, important information is acquired on the style of mineralization. The presence of broad anomalies containing samples with high proportions of pristine grains may suggest a style of mineralization involving sulphide-hosted gold. In the modified class of gold grains, the original shape of the gold grain is retained, however, irregular edges and protrusions are crumpled, folded and curled. Grain molds and primary surface textures are only observed on protected faces of the grains. Modified grains also commonly display striated surfaces. Where a till sample contains above background levels of modified grains, the bedrock source is generally proximal to the sampling site. Reshaped gold grains fail to retain any of their pristine textures. Grains often display a robust to flat- tened or rounded profile resulting from the abrasion or repeated folding of leaves, wires and rods. The grain surfaces are typically pitted or etched due to surface leaching of silver. Reshaped grains are usually present in small numbers across most shield terranes of Ontario. These grains can have a complex transport history and are, therefore, difficult to assess in terms of their source. The presence of large numbers of reshaped grains within discrete areas should be considered significant. Our current understanding of how glacial processes of erosion, transport and deposition result in the modification of gold grains is not far enough advanced to disregard such occurrences. In general, large numbers of gold grains within any given sample should be treated as potentialy significant regardless of grain shape characterization. The regional distribution of particulate gold in till is plotted in Figure 7. A complementary plot depict- ing the ratio of the sum of “pristine+modified” grains to the “total” number of grains at a given site [(P+M)/T] is illustrated in Figure 8. Data intervals for the proportional dot plots were established using percentile statistics. The greater than 95th percentile is considered to represent the anomalous population. Most till samples collected from the study area contain less than 5 visible gold grains. The regional background concentration of gold grains over the Shebandowan greenstone belt appears to be somewhere in the order of 1 to 3 grains per 10 kg table feed. Background levels fall to 0 or 1 grain per 10 kg table feed over the Quetico Subprovince to the north and the Proterozoic Gunflint and Rove formations to the south. Local variations in background gold grain content within the Shebandowan greenstone belt do exist and probably reflect lithological controls on mineralization. Background gold may occur in 2 distinct forms. It may be produced by the continuous recycling of grains, over an extended period of time, by glacial and non-glacial processes, with a final depositional site some distance from its source. Background gold may also display a local to semi-local signature that defines a geochemical province of enhanced gold potential. These areas are defined by groups or clusters of samples containing elevated concentrations of reshaped grains. These grains have been transported only a short distance from their source; perhaps only a few hundred metres. Studies in the Swayze greenstone belt of northeastern Ontario, in the vicinity of the Jo-

11 12 13 burke gold mine, suggest the ratio of pristine to reshaped grains decreases rapidly in response to glacial transport resulting in a predominance of reshaped grains 300 to 400 m down-ice from source (C. Kaszycki, Ontario Geological Survey, personal communication, 1996). Most gold grains recovered as part of this study are silt sized. The apparent small size of the gold grains may simply reflect transport history (i.e., amount of folding, crumpling, flattening, etc. during glacial transport). It may also provide a clue as to the nature of gold mineralization within the study area (i.e., fine versus coarse gold). This has important implications for the interpretation of non-magnetic heavy mineral geochemistry and threshold anomalies. A strong correlation between numbers of gold grains and neutron activation values for the non-magnetic HMC is often lacking since large numbers of small grains usually yield low to moderate geochemical results. Samples with low grain counts may yield very anomalous neutron activation geochemistry if the grains are large (i.e., greater than 100 microns). For this reason, the explorationist should consider fine fraction geochemistry (i.e., -63 micron size fraction of till) as the pre- ferred fraction for gold geochemical surveys involving till within the study area. A number of excellent gold exploration targets have been identified within the study area based solely on the gold grain content of tills (Figure 7). These anomalies are, in most cases, defined by clusters of samples with anomalous or elevated gold grain counts. Single sample anomalies have also been identified and are considered significant because of the sampling density. An attempt will be made to discuss each of these anomalies in terms of possible source based on an interpretation of grain shape and local geology. A cluster of 12 till samples collected from the west end of Dawson Road Lots returned anomalous gold grain counts and define an important exploration target within the study area (Figure 7, Anomaly A). This anomaly is defined by samples 017, 044, 049, 284, 285, 286 and 287, all of which contain gold grain counts greater than the 95th percentile (>15 grains) for the entire study area. Weaker responses within the same anomaly occur in samples 050, 102, 137, 138 and 139, all of which contain gold grain counts greater than the 90th percentile (6 grains). This large anomaly can be subdivided into 3 distinct geological environ- ments, namely: 1) those samples collected in close proximity to the Keewatin-Timiskaming fault-controlled unconformity (Bylund occurrence); 2) those samples collected over Keewatin metavolcanic rocks (West occurrence and Gold Cache Trenches); and 3) those samples collected over Timiskaming metasedimentary rocks (Sheppard Zone and Godzic occurrence). Sample 017 was collected immediately over the Bylund occurrence and returned a grain count of 83 grains, 79 of which displayed either a modified or pristine shape. This information is extremely useful for the interpretation of the gold grain counts from other sites within this anomalous area. Samples 284 and 285, which were collected from trenches less than 200 m west-northwest of the Bylund occurrence, returned gold grain counts of 698 and 252 grains, respectively. A large majority of these grains displayed modified and pristine shapes, suggesting a proximal source for the gold. Both samples were collected on the up-ice side of a prominent bedrock ridge from material interpreted to be lodgement till. Sample 284 was collected from just above the bedrock surface, up-ice of the exposed alteration zone to the south. Nu- merous quartz-carbonate altered clasts were observed within the till sequence at the north end of the trench strongly suggesting the presence of additional alteration zones in the up-ice direction. The source rocks are likely less than a few hundred metres north of the sample site. The situation at sample site 285 is very similar to that described above. In a visit to the trench early in the field season, Bernie Schnieders (Resident Geologist, Thunder Bay South) recovered a clast of altered float containing black chert fragments from the till sequence where sample 285 was collected. The sample assayed 1.6 g/t Au (C. Bishop, Freewest Resources, personal communication, 1999). At the Bylund occurrence, mineralization is closely associated with a similar black chert unit. It is unclear whether the black chert represents a primary stratigraphic marker horizon or was emplaced by silica flooding along a major fault that follows the Timiskaming-Keewatin unconformity. This easily recognized lithology has not been observed in outcrop immediately west of the main Bylund showing but has been traced westward on adjacent properties (B. Schnieders, OGS, personal communication, 1999). This discovery therefore suggests a westerly extension of the unit north of the trenched areas. The anomalous gold grain counts and high proportion of pristine and modified grains (91%) obtained from the till sample where this float sample was collected also suggests the presence of auriferous host rocks in the up-ice direction. Both of these anomalies should be followed up with additional trenching to the north. Overburden thicknesses are increasing to the north, however, and may limit the amount of trenching possible. Deep testpitting and sampling of the till may prove useful in areas of thicker drift to assist with the delineation of mineralized float in till.

14 Trenching further to the west along lines 1W and 2W is also recommended based on the soil geochemistry results. A second cluster of anomalous till samples were recovered 1 to 3 km west of the Bylund occurrence from trenches collectively referred to as the “Gold Cache Trenches”. Of particular interest is the 59 grains recovered from sample 287, of which 47 had modified or pristine shapes. The sample site is underlain by mafic-intermediate metavolcanic rocks and is situated approximately 1.6 km west of the “West Occurrence” where pyritized shear zones in mafic-intermediate metavolcanic rocks have returned Au assays of up to 5.5 g/t (Carter 1990a). A program of high-density till sampling is recommended to follow-up this anomaly. Till samples should be collected at 100 m centres for geochemistry to further refine this anomaly. The source for the gold at site 287 is likely within a few hundred metres north of the sample site. Elevated gold grain counts were also obtained from 3 till samples collected along a hydro line immediately south and east of the Bylund occurrence in Dawson Road Lots (samples 137, 138 and 139). Samples collected along Highway 11/17, immediately up-ice from this area returned low grain counts. It is therefore likely that a bedrock source occurs somewhere between the highway and hydro line in this vicinity. As with the previously discussed group of samples, this group was collected from Keewatin mafic metavolcanic terrane. A program of high-density till sampling is recommended to follow-up this anomaly. A third cluster of till samples at the west end of Dawson Road Lots occurs north of Highway 11/17 in Timiskaming (Shebandowan assemblage) metasedimentary rocks. The Godzic Au occurrence and Shep- pard Zone occur in this environment. The anomaly is defined by elevated to extremely anomalous gold grain counts in samples 044, 049 and 050. These anomalous samples were collected from exploration trenches opened by Freewest Resources and Battle Mountain Gold under a joint venture. Samples 049 and 050 were collected from trenches where Au mineralization occurs in arkoses cut by lamprophyre dikes and quartz veins and that have undergone strong iron-carbonate alteration and contain 1 to 3% pyrite. Grab samples collected by the Stares brothers returned values ranging from 1.5 to 6.8 g/t Au. Sample 049 was collected from the south end of Freewest’s Main Zone trench and contained 17 gold grains, 15 of which had a pristine shape. Mineralized rock exposed in the trench is the likely source for the gold. Channel sampling returned grades of 1.25 g/t Au over 25.0 m (C. Bishop, Freewest Resources, personal communication, 1998). Sample 050 was collected over the Sheppard Zone where channel samples returned values of 1.33 g/t Au over 24.5 m. The till sample contained only a slightly anomalous gold grain count. Of particular interest is the gold grain count obtained from sample 044. This sample was collected from an exploration trench opened by Freewest Resources as a result of the discovery of numerous, angular, iron-carbonate altered boulders grading up to 5 g/t Au on the surface of a bedrock ridge. A diamond drill hole at the site returned an intersection of 1.7 g/t over 5.7 m. Trenching over the ridge failed to uncov- er the source for the mineralized boulders. However, numerous angular, iron-carbonate altered clasts were present in the till sequence exposed in the trench. Till collected from the up-ice side of the trench returned a gold grain count of 213 grains, 88% of which had a pristine shape. A second till sample collected 500 m to the north did not contain any visible gold grains. The source of this anomaly is therefore most likely situated within a narrow swale, only a few hundered metres wide, separating these 2 samples. Additional trenching and testpitting is recommended to more precisely define the source of the mineralized boulders. A second important anomaly has been identified in central Conmee Township, at the east end of the Tower Syenite Stock (Figure 7, Anomaly B). The Tower Syenite has long been explored for gold and currently contains greater than 20 occurrences including a proven resource of 60 000 t grading 3.0 g/t Au. The intrusion is a composite stock consisting of an outer rim of quartz monzonite and a core of monzodiorite- diorite-gabbro including some lamprophyre. Mineralization occurs primarily along the western edge of the intrusion in highly-altered metavolcanic and metasedimentary rocks and contact breccias (Lavigne and Scott 1994). The contact breccias host the most significant mineralization. Hematitic alteration occurs on the margins of the stock and is often closely associated with mineralization. To date, there are no known Au occurrences on the eastern side of the stock. The gold grain response over and down-ice from the western edge of the stock is subdued. Grain counts, ranging from 2 to 5, occur within this area and are likely a result of glacial dispersal from mineralization at the western edge of the stock. Background grain counts north of the intrusion are 0. Two samples collected from the southeastern corner of the intrusion returned extremely anomalous gold grain counts. Sample 269, which is located approximately 0.5 km south of the intrusion, contained 119 grains, 61% of which were modifed and pristine shaped. The bedrock underlying the sample site has been mapped

15 as calc-alkalic or shoshinitic lapilli tuff (Shebandowan assemblage) containing an igneous or welded matrix (Carter 1990b). Of particular interest is the presence of approximately 300 grains of cinnabar (mercury sulphide) in the heavy mineral concentrate. Cinnabar is associated with mineralization at such prolific gold camps as Hemlo and Red Lake. It is very unusual to find cinnabar in the heavy mineral concentrate of surface till samples because it deteriorates quickly during glacial transport and by oxidation in the surface environment (R. Huneault, Overburden Drilling Management, personal communication, 1999). Its occurrence is therefore especially significant. No known Au occurrences are associated with this anomalous sample. Sample 130 was collected from within the Tower Syenite intrusion, approximately 1 km north of site 269. The sample contained 28 grains, 93% of which had a modified or pristine shape. The underlying bedrock adjacent to the site is a hornblende diorite (Carter 1990b). The shapes of the grains at both sites suggest a local source for the gold. A follow-up program of till sampling employing geochemistry is recommended to further refine the possible source of these anomalies. A third weaker anomaly, defined by 3 anomalous till samples, is located in the Binabick Lake area of central Conmee Township (Figure 7, Anomaly C). The northwest-trending anomaly appears to be associated with a zone of mafic to ultramafic intrusive rocks interdigitated with calc-alkalic intermediate and tholeiitic mafic metavolcanic rocks and minor jasper-magnetite iron formation (Keewatin supracrustals). The gold grain anomaly is defined by samples 073 (15 grains), 074 (19 grains) and 098 (28 grains). Most of the gold grains in samples 073 and 074 are reshaped or modified whereas approximately 54% of the grains in sample 098 display modified or pristine shapes. The outcrop adjacent to sample 098 was highly sulphidized and should be investigated as a possible source. It is recommended that a follow-up program of till sampling be undertaken within this diffuse anomaly to better define possible exploration targets. A fourth anomaly, situated in west-central Aldina Township (Figure 7, Anomaly D) and consisting of 3 anomalous till samples clearly defines a region of elevated mineral potential. Samples 227, 228 and 229 contain 7, 16 and 8 gold grains, respectively. Most of the grains are reshaped indicating at least some level of transport by glacial processes. However, 4 till samples collected along the Boreal Road, a few kilometres to the north, returned gold grain counts of 0 to 3 grains and 4 till samples collected over granitic terrane to the south returned counts of 1 to 2 gold grains. Two of the samples (227 and 228) within the anomaly were collected over high grade mafic metavolcanic terrane whereas sample 229 was collected over felsic intrusive rocks. Most of the area has been metamorphosed to amphibolite grade. It is recommended that a follow-up program of prospecting and low-density till sampling be undertaken between the Boreal Road and the anomaly to better define potential source rocks for the anomaly. Areas of elevated background warranting further work include the northeastern corner of Aldina Town- ship (Figure 7, Anomaly E) where several till samples containing 4 to 13 grains have been collected. This region has received increased exploration activity over the last 5 years due to the discovery of Zn-Cu-Pb- Ag-Au float with exceptional grades on a logging road north of the Boreal Road. A Cu-Mo-Au occurrence also occurs within this area. A second area of elevated gold grain background occurs in northeastern Sack- ville Township (Figure 7, Anomaly F) where several samples containing 4 to 15 gold grains were collected. The area is primarily underlain by mafic metavolcanic rocks. Follow-up till sampling is recommended for both of these areas to assess the significance of the elevated background in these 2 regions. A few single sample anomalies have also been documented from the study area. These include sample 288 in west-central Blackwell Township (Figure 7, Anomaly G) which returned a gold grain count of 11 grains, most of which have pristine and modified shapes and sample 184 in southwestern Horne Township (Figure 7, Anomaly H) which returned a gold grain count of 15 grains, half of which have pristine and modified shapes. Prospecting and possible follow-up till sampling in the immediate vicinity of these anomalies is required to further evaluate their significance. Mineralogy As part of the heavy mineral processing contract, 183 of the 288 submitted till samples were processed for kimberlite indicator minerals (KIM) and metamorphosed/magmatic massive sulphide indicator minerals (MMSIM). The 0.25 to 2.00 mm non-magnetic heavy mineral concentrates were picked for kimberlite indicator minerals (Cr-diopside, chromite, Cr-pyrope garnet, Cr-poor pyrope garnet, eclogitic pyrope (alman- dine garnet) and Mg-ilmenite. The 0.25 to 0.5 mm non-magnetic and paramagnetic fractions were picked for MMSIM’s. Common metamorphosed massive sulphide indicator minerals include gahnite, Cr-rutile, spessartine, Mn-epidote, staurolite and anthophyllite. Common magmatic massive sulphide indicator min-

16 erals include olivine, chromite, bronzite and chalcopyrite. The detailed results of the KIM and MMSIM investigations will be released as a separate report, however, some comments regarding mineral assemblages and unusual or significant occurrences is warranted. The non-magnetic heavy mineral concentrate of most till samples (Patrician and Superior lobe tills) collected and analyzed for KIMs and MMSIMs is dominated by the mineral pigeonite, a brown, Ca-poor clinopyroxene that is gradational to Ca-poor augite. This mineral is so abundant that it has resulted in heavy mineral concentrates with unusually high weights for samples collected from the shield terrane of Ontario. Weights of the –2 mm non-magnetic heavy mineral concentrate (>3.2 S.G.) derived from samples initially weighing 10 kg, commonly exceed 300 or 400 g. Weights in the range of 40 to 50 g are more typi- cal of samples collected from Archean greenstone belts of Ontario. The likely sources for the pigeonite are the laterally extensive sills of Nipigon diabase which occur 70 km northeast of the study area as well as the large mesas formed by sills of Logan diabase at the southern end of the study area. Pigeonite occurs in lithic fragments of olivine diabase in the coarser fractions of the non-magnetic heavy mineral fractions (0.5-2.0 mm) that were picked. The Nipigon diabase has an aerial extent of over 15 000 km2 and is composed of approximately 40 to 50% pyroxene (S. Averill, Overburden Drilling Management, personal communication, 1998). It is therefore likely that the source of the pigeonite for Patrician (northern) derived tills is the Nipigon diabase rather than the local bedrock within the study area which contains less than 0.5% heavy minerals. Superior lobe tills probably derive their pigeonite from the Logan diabase as well as from the recycling of older, northern-derived glacial deposits. Because of the extreme dilution of the non-magnetic heavy mineral concentrate with pigeonite, it is not recommended that heavy mineral geochemistry be performed for exploration purposes. The geochemical signature of the concentrate would most likely be overwhelmed by the composition of the pyroxene showing very subtle variations related to local geological conditions. The evaluation of mineral potential based on the isolation of gold grains, KIMs and MMSIMs from the heavy mineral concentrate is effective since every indicator mineral grain is extracted. PYRITE Despite being highly susceptible to surface oxidation, a remarkable number of till samples contained large numbers of pyrite grains in the 0.25 to 0.5 mm non-magnetic heavy mineral fraction (Figure 9). Their occurrence may have economic significance. Of particular note are samples 017 (~3000 grains), 044 (~100 grains), 146 (~5000 grains), 167 (~250 grains), 238 (~1000 grains) and samples 202, 275, 276 and 281, all of which contained greater than 95% pyrite in the 0.25 to 0.5 mm non-magnetic heavy mineral fraction. Samples 017, 044, 146, 202 and 238 are derived from Patrician (northern) drift whereas samples 167, 275, 276 and 281 were collected from the base of thick exposures of Superior lobe till. The high pyrite content of the Superior lobe deposits is undoubtedly related to their lack of oxidation as well as the high sulphide content of the Rove and Gunflint formation source rocks. The high pyrite content of samples collected over Archean source rocks may indicate economically significant conditions. For example, sample 017 was collected over the Bylund Au occurrence in Dawson Road Lots. It should be noted that sample 238 consisted of a poorly sorted sand and gravel collected from a steep slope fringing the south shore of Twin Birch Lake in Adrian Township. Its occurrence should still be considered significant. CHALCOPYRITE Grains of chalcopyrite were recovered from many of the till samples as well, although at much lower concentrations than pyrite (Figure 10). Chalcopyrite is less susceptible to surface oxidation than is pyrite. Its occurrence should be considered more significant than that of pyrite since it is an ore-forming mineral. Twenty-three samples contained one or more grains of chalcopyrite. Of particular interest is a northeast- trending cluster of 9 samples in Conmee Township and adjoining Dawson Road Lots that contain detrital chalcopyrite (Figure 10, Anomaly A) . This cluster is defined by samples 031 (1 grain), 140 (2 grains chalcopyrite and 1 grain malachite), 070 (5 grains), 071 (3 grains), 159 (3 grains), 077 (2 grains), 163 (1 grain), 162 (2 grains) and 165 (1 grain). This occurrence may provide some insight into the base metal potential of the felsic-intermediate metavolcanic rocks within Conmee Township and Dawson Road Lots. The Mud Lake copper-zinc occurrence, which is located along Highway 102 at the eastern end of Dawson Road Lots (Figure 10, ML) and is hosted by interbedded chemical metasedimentary rocks and felsic-intermediate pyroclastic metavolcanic rocks, attests to the base metal potential of this region. The occurrence of

17 18 19 5 and 3 grains of chalcopyrite in samples 070 and 071, respectively is interesting in that zinc-rich float was encountered in this area as well. A discussion of this float occurrence is located in the section entitled “Float”. Grains of chalcopyrite were also commonly encountered in Superior lobe till samples collected over the Rove Formation shales and/or in close proximity to the Logan diabase sills (Figure 10, Anomaly B). Sam- ple 276 was collected from an exploration trench in the Rabbit Mountain area (Gillies Township) where the Creswel or Rabbit Mountain group of silver deposits is located. This sample contained 10 grains of chalcopyrite, 12 grains of sphalerite, approximately 30 grains of barite, 2 grains of fluorite and approximately 95% pyrite in the non-magnetic heavy mineral concentrate. Franklin et al. (1986) have reported all of these minerals as accessories to vein silver deposits in the Thunder Bay area. A similar mineral assemblage was recovered from the base of a thick exposure of till in the Whitefish River valley. Sample 275 contained 1 grain of chalcopyrite, 10 grains of sphalerite, approximately 40 grains of barite, 3 grains of galena and approximately 98% pyrite. This assemblage may suggest the presence of additional vein-type sources of silver mineralization within the Whitefish River valley. Mineralogy of the non-magnetic heavy mineral fraction of till should be considered as a viable exploration tool for vein-type silver deposits within this region. Other notable occurrences of chalcopyrite include 5 grains in samples 015 and 146, 2 grains in samples 085 and 190 and single grains in samples 067, 135, 224, 251 and 283. Sample 015 was collected over Quetico subprovince metasedimentary terrane in north-central Goldie Township. This occurrence should be investigated and, if warranted, additional till sampling should be undertaken to further refine the exploration target. Sample 146 was collected from a gravel pit in central Oliver Township between the 5th and 6th Concessions just east of the 6th Sideroad; the sampled material is interpreted to be a northern derived till. A single grain of bornite was also recovered from the heavy mineral concentrate in addition to the chalcopyrite. The significance of this occurrence is difficult to determine as there are few outcrops in the immediate vicinity. An outcrop of felsic metavolcanic rocks does occur, however, along the 6th Concession northeast of the sample site. Geophysics may help to identify potential source rocks in this region. Sample 283 was collected approximately 1 km northeast of where the Stares Zn-Cu-Pb-Ag-Au float was discovered in Aldina Township. This occurrence may lend support to a local source for the mineralized float. CHROMITE Significant numbers of chromite grains were recovered from many of the heavy mineral concentrates as part of this survey (Figure 11). Notable grain counts were obtained from samples 084 (~80 grains), 172 (165 grains), 238 (~100 grains) and 257 (~3500 grains). Slightly elevated grain counts were also obtained from samples 077, 080, 171, 237 and 246. With the exception of one sample (246), all of these samples are situated in southeastern Adrian Township and southwestern Conmee Township. The chromite grains within this region are likely of crustal origin, derived from large mafic and ultramafic intrusive rocks mapped within these townships (Carter 1990b; Rogers and Berger 1995). For example, sample 257 was collected over mafic-ultramafic intrusive rocks mapped as olivine gabbro and serpentinite. The heavy mineral concentrate contained approximately 3500 grains of chromite. This rather discrete zone of elevated chromite grains in till forms part of a much larger zone containing samples with 1 to 5 chromite grains. This diffuse zone is northeast-trending and extends from south-central Aldina Township to northwestern Conmee Town- ship. Both the northwestern and southeastern margins of this zone are abrupt with only a few scattered samples lying outside of the zone. Glacial dispersal may be, in part, responsible for the orientation of this interesting chromite anomaly. The occurrence of large numbers of chromite grains in till may have some economic significance in that they can point to areas of ultramafic source rocks with high Ni-Cu-Cr-Co- PGE potential. At the Shebandowan mine site in Hagey Township west of the study area, chromite mineralization of uneconomic significance occurs within a serpentinized peridotite at the intersection of 2 major faults. Finely disseminated chromite also occurs in other ultramafic rocks of the Shebandowan area (Os- mani 1997).

20 21 In an area south of the Shaw Dome within the Abitibi greenstone belt, similarly large numbers of chro- mites were recovered from till samples as part of a regional till sampling program (Bajc 1996, 1997). In this area, the source rocks are most likely komatiitic flows and possibly, ultramafic intrusive lithologies similar to those recently discovered by Band-Ore Resources in Nordica Township. The chemistry of the chromite grains is being investigated and may yield clues as to the nature of the source rocks and their possible fertility. Studies are ongoing at the Ontario Geological Survey in this regard. Humus and Till Geochemistry Aside from providing information on the background concentration of metals in the surficial environment, the humus and c-horizon till geochemical datasets have identified a number of potentially significant exploration targets. These targets will be subdivided into 3 categories based on type or style of mineralization: 1) lode or shear-hosted gold mineralization including the elements Au, As and Sb; 2) VMS base metal mineralization including the elements Cu, Zn and Cd; and 3) mafic-ultramafic hosted mineralization including the elements Ni-Cu-Cr-Co. The humus and till geochemical datasets will be discussed simultaneously to allow for a comparison of the observed patterns. Because of their markedly different source rocks and grain size characteristics, Patrician (northern) and Superior lobe tills display distinct geochemical signatures. For this reason, it was deemed necessary to treat the 2 till units as separate populations to allow for the calculation of their respective threshold anomalies. A remarkably similar situation was observed in the Rainy River district of northwestern Ontario where both Keewatin and Labradorean derived tills overlie the Archean terrane (Bajc 1991). Au-As-Sb Numerous gold exploration targets defined by anomalous concentrations of AuAsSb in till and/or humus have been identified as part of the geochemical program (Figures 12-17). The concentrations of these elements in till and humus were all determined by neutron activation analysis and therefore represent the total concentration within the sample. This is particularly important for the till dataset in that silicates may hold a significant proportion of the Au. Approximately 30 to 40 g aliquots of –63←m till were irradiated thus reducing the possibility of a nugget effect caused by single large grains of Au within a sample. Most of the Au results for humus are at or below the quoted detection limit of 2 ppb (Figure 12). Precision for Au by neutron activation analysis is generally in the range of 3 to 4 ppb, therefore only those samples containing greater than 4 to 5 ppb gold are considered anomalous. The user is cautioned to use the Au humus data as a supportive rather than primary tool for the definition of exploration targets within the study area. The patterns of Au, As and Sb in till and humus are not unlike those depicted by the gold grain dataset. Important geochemical anomalies defined by elevated Au, As and Sb in till and, to a lesser extent, in humus occur along Highway 11/17 at the west end of the Dawson Road Lots (Figures 12-17, Anomaly A). Gold values of greater than 50 ppb in till are not uncommon within this area. Most samples that contained anomalous gold grain counts also returned anomalous Au geochemistry. This anomalous area clearly stands out as one of the most important Au exploration targets within the study area. Elevated Au in humus occurs at the Bylund occurrence along Highway 11/17. Further to the west, within an area referred to as the Gold Cache Trenches, humus from site 287 returned a Au value of 236 ppb and an As concentration of 91.1 ppm. These humus values are, by far, the highest reported from the entire survey area. It is possible that the sample may have contained a small grain of gold as the sample was collected adjacent to a trenched area. Regardless, the sample is regarded as extremely significant and should be followed up. Anomalous to elevated As values in both humus and till lie along an inferred break that straddles Highway 11/17, in the vicinity of the Bylund occurrence, and extend westward into northern Laurie Township where abundant Fe-carbonate alteration has been observed (Figures 14 and 15). A splay off of the main break is inferred and may be responsible for this geochemical pattern. Anomalous concentrations of Sb in till occur over and adjacent to the Bylund occurrence as well as to the north at sample site 044 where 213 gold grains were recovered from an exploration trench (Figure 17). The Sb signature for humus over this area is weak (Figure 16). Elevated to anomalous concentrations of Au and Sb in till were observed in north-central Conmee Township along the southeast side of the Tower Syenite intrusion (Figures 13, 17, Anomaly B). Corre- sponding humus anomalies were not registered within this area. Humus samples collected south of the intrusion are only slightly elevated in Au (Figure 12, Anomaly B). Samples 128 and 269 returned Au values

22 23 24 25 26 27 28 of 37 and 48 ppb, respectively. The lack of an As anomaly in till is curious. At the Matachewan Consoli- dated Mine in northeastern Ontario, Au mineralization is associated with a Timiskaming-type alkalic-sub- alkalic intrusion similar to the Tower Syenite. Till samples collected over mineralization often returned As values greater than 25 ppm (Bajc 1997). At the Tower Syenite, As values in till are generally less than 4 ppm. As stated earlier, this anomaly definitely warrants further work. Till geochemistry clearly is the pre- ferred medium for follow-up surficial geochemical surveys. Elevated to anomalous levels of Au, As and Sb also occur in till and humus within a broad zone southwest of the intrusion (Figures 13-17, Anomaly C). The As and Sb anomalies are more restrictive and best defined by the humus geochemical datasets. Anomalous geochemical values lie along a narrow, northwest- trending target extending from the 6th Concession of Conmee Township towards Thunder and Gold lakes. The anomaly is underlain by mafic to ultramafic intrusive rocks interdigitated with calc-alkalic intermediate and tholeiitic metavolcanic rocks and chemical metasedimentary rocks. A coincident pattern of anomalous gold grain counts was obtained from till within this area. The anomaly depicted by Au geochemistry of till is much larger, extending northeastward into terrain underlain by alkalic, intermediate metavolcanic rocks of the Shebandowan assemblage. This broad zone of anomalous Au requires follow-up work to more precisely define potential source rocks. A number of other single or multi-element anomalies have been identified within the study area. Fol- low-up work should be performed at all of these to establish their significance. Anomalous Au values were obtained from humus and till samples collected at sample site 065 in west-central Horne Township (Figures 12 and 13). Values of 7 and 30 ppb Au were obtained from the humus and till samples, respectively. The sample site is located near the contact between Shebandowan assemblage metasedimentary rocks and Greenwater assemblage metavolcanics. Anomalous Au values in till were also registered in till samples 179 in east-central Sackville Township (24 ppb) and 238 in southwestern Adrian Township (43 ppb) (Fig- ure 13). No known mineralization is associated with these elevated values. Till samples 089 in northwestern Adrian Township and 186 in east-central Horne Township returned anomalous concentrations of As and Sb despite containing low concentrations of Au (Figures 15 and 17). These anomalous values require follow-up work to establish whether favorable source rocks and structures are present that may host gold mineralization. Anomalous levels of As and Sb in humus at site 086 in central Adrian Township is worthy of further work as well (Figures 14 and 16). This anomaly lies within a large tract of interpreted Shebandowan assemblage metasedimentary rocks. Most till samples collected over metasedimentary rocks transecting the southern half of Adrian Town- ship and northern Marks Township display elevated As concentrations. This is attributed to what is probably elevated background concentrations of As in the host metasedimentary rocks of this region. A few sites have yielded anomalous concentrations of Sb in humus. These include: sites 228 and 235 in central and northeastern Aldina Township, respectively; sites 181 and 182 in central Sackville Township; and site 270 in north-central Oliver Township. Superior lobe tills in the southeastern corner of the study area are elevated in Au, As and Sb especially along the fringes of the Logan diabase sills. This response may in some way be related to contact type mineralization as occurs between the Logan diabase and the underlying Rove Formation shales. Till geochemistry may therefore prove useful as an exploration tool for vein-type silver mineralization in this region. Ni-Cr-Co Mafic and ultramafic rocks are host to, or closely associated with, Au and Ni-Cu mineralization within the Shebandowan greenstone belt. At the Bylund occurrence in Dawson Road Lots, mafic-ultramafic rocks are associated with Au mineralization. Mineralization at the INCO Limited Shebandowan Mine, to the west of the study area, is hosted by serpentinized peridotite and gabbro to amphibolite sill-like bodies (Osmani 1997). Similar rock types occur in Adrian and Conmee townships (Rogers and Berger 1995; Carter 1990b). The current geochemical and mineralogical survey has clearly shown that surficial media respond closely to the presence of these rock types (Figures 18-23). Strong Ni-Cr-Co geochemical anomalies occur in till samples collected along a 2 km stretch of High- way 11/17 in the vicinity of the Bylund occurrence (Figures 19, 21 and 23, Anomaly A). Spinifex textured rocks and chrome-rich mica (fuchsite) have been observed in outcrops on and adjacent to the Bylund show-

29 ing. The Ni-Cr-Co anomaly in till extends 2 km east of the Bylund occurrence and suggests favourable lithologies may be present. The eastern and western margins of this anomaly are abrupt. A strong Ni-Cr anomaly in till occurs along the eastern third of Adrian Township and the western third of Conmee Township (Figures 19 and 21, Anomaly B). The Co response is less extensive and appears to be confined to the southern half of the Ni-Cr anomaly (Figure 23, Anomaly B). Aerially extensive mafic and ultramafic rocks have been mapped throughout this region and are the likely source of this geochemical anaomaly. The highest Ni and Cr responses were obtained from sample 257 which contained 392 ppm Ni and 412 ppm Cr. It is unclear whether the halo of elevated Ni-Cr-Co located southwest of this intense anomaly is a reflection of glacial dispersal from these source rocks. Scattered mafic to ultramafic intru- sives have been mapped throughout Adrian Township and may be, in part, responsible for this diffuse pattern. Superior lobe till samples collected from the extreme southeastern corner of the study area returned anomalous Ni concentrations as well (Figure 19, Anomaly C). This is attributed to the underlying Logan diabase that occurs within this area. Isolated Cr in till anomalies (Figure 21) occur along the Laurie-Horne township border (samples 064 and 065), where anomalous gold in till and humus values were reported: in southeastern Sackville Township (sample 183) where mafic sills have been mapped (Rogers and Berger 1995); and in west-central Oliver Township where felsic-intermediate metavolcanics are present (Brown 1995). Isolated Co in till anomalies occur in northwestern Adrian Township in an area where thick clay cover conceals much of the bedrock surface and prevents a simple evaluation of the areas mineral potential (Figure 23). The local bedrock consists of intermediate metavolcanics (Rogers and Berger 1995). Elevated to anomalous levels of Co in till also occur in auriferous till samples collected south of the Tower Syenite intrusion as well as in the southeastern corner of Conmee Township where calc-alkalic felsic metavolcanic rocks occur. The humus signature for Ni is obscured and overwhelmed by an apparent anthropogenic source along Highway 11/17 (Figure 18a). It was drawn to the author’s attention that when the Shebandowan mine was initially opened, the Ni-Cu concentrate was hauled by dump truck from the mine site to a railway siding between the hamlets of Sunshine and Sistonens Corners (junction of Highway 11/17 and 102). An over- whelming Ni anomaly along Highway 11/17, extending from the western edge of the map area and termi- nating at the junction with Highway 102 is a testament to these early days of production at the Shebando- wan mine. The geochemical dataset for Cu in humus displays a similar pattern. Both Ni and Cu are the main ore-forming elements at the Shebandowan mine. Figure 18b depicts the Ni content of humus derived from a dataset where samples collected along Highway 11/17 have been removed. Elevated background levels of Ni and Cr in humus in Adrian and Conmee townships is attributed to the large areas of mafic-ultramafic rocks mapped within these areas (Figures 18b and 20). Elevated background levels of Ni-Cr-Co also occur over the southern portion of the Quetico Subprovince where mafic intrusions along the subprovincial boundary may be responsible for this distinctive geochemical signature. The significance of this pattern should be investigated as a potential source of Ni-Cu-PGE mineralization. Unfortunately, a coincident anomaly in till does not occur within this area. Isolated Ni-Cr humus anomalies occur in east-central Laurie Township (sample 062), northwestern Conmee Township (sample 121) and central Conmee Township (sample 072). These anomalies may warrant further investigation. Isolated Co anomalies in humus occur in: western Dawson Road Lots (sample 287), where anomalous Au and As values were also recorded; northeastern Aldina Township (samples 092, 093, 094 and 235), in the vicinity of the Stares Float base metal discovery; north-central Conmee Township (sample 098), where mafic-ultramafic rocks occur; and eastern Dawson Road Lots (sample 031), along the contact between Quetico subprovince mudstones and Keewatin tholeiitic mafic metavolcanics (Figure 22). All of the anomalies discussed above require further evaluation.

30 31 32 33 34 35 36 37 Cu-Zn-Cd The Cu-Zn-Cd datasets define numerous base metal targets within the study area worthy of follow-up work (Figures 24-29). Most of the anomalies are defined by 1 or 2 samples, however, a few are defined by clusters of 2 to 4 samples. Both single and cluster anomaly types are considered significant. The clusters are interesting in that they often define favourable lithologic units with elevated base metal potential. There are 3 main anomalous geochemical trends that will be discussed with regards to potential Cu-Zn- Cd mineralization. Numerous till samples collected over the western end of the Dawson Road Lots contain elevated concentrations of Cu and, to a lesser extent, Zn and Cd (Figures 25, 27 and 29, Anomaly A). All 3 elements are anomalous over the Bylund occurrence. Elevated Cu concentrations occur to the north and west as well forming a subtle halo around the showing (Figure 25). The source of this base metal signature is not known. Slightly elevated Zn levels in humus occur within this same general area (Figure 26, Anom- aly A). Anomalous Cd levels occur in humus just east of the Bylund showing as well as at sample site 287 where high concentrations of Au, As and Co occur in humus (Figure 28). Elevated to anomalous concentrations of Cu-Zn-Cd in till also occur within a large area spanning Con- mee, Adrian and the eastern portion of Sackville townships (Figures 25, 27 and 29, Anomaly B). Within this area of elevated background are anomalous samples containing in excess of 110 ppm Cu, 100 ppm Zn and 11 ppm Cd. Notable Cu anomalies include: sample 123 located along the northern portions of the Sackville/Adrian township boundary; sample 249 in northeastern Adrian Township, which also has a coincident Zn and Cd anomaly in till; and samples 121 and 071 in northwestern and east-central Conmee Township, respectively, both of which also have elevated Zn levels in till. Humus from site 121 also returned anomalous Zn concentrations. Anomalous concentrations of Zn occur in sample 094 in northeastern Aldina Township and sample 236 in northwest Marks Township. Sample 094 was collected adjacent to where the Stares base metal float was discovered and may lend support to a local source for the boulder. Pebbles isolated from the till collected at site 094 consist mainly of felsic-intermediate metavolcanic rocks, some of which are sericitized. The occurrence of other mineralized surface float samples in the immediate up-ice direction from the Stares discovery site suggests the possibility for a local source of mineralization. Slightly elevated Zn values were also obtained from samples 093 and 282 immediately to the east. A strong Zn in humus anomaly in northwest Marks Township is clearly one of the most significant humus anomalies encountered in this survey (Figure 26, Anomaly C). The anomaly consists of 6 samples (107, 108, 233, 234, 235 and 236), 4 of which returned Zn values above the 98th percentile value of 322 ppm. All of these samples are also enriched in Ba. Only one till sample (sample 236) within this anomaly contained anomalous concentrations of Zn. Metasedimentary rocks have been mapped throughout this area. This geochemical signature may provide information on the base metal potential of these rocks. This significant anomaly warrants additional field work to assess its significance. Invesigations should begin near site 236, where till geochemistry was also anomalous. A processed dataset of Cu in humus omitting the samples collected along Highway 11/17 in the con- taminated region is presented in Figure 24b. As with the Ni-Cr-Co datasets, Cu concentrations are elevated over the Quetico Subprovince, especially in Forbes and Ware townships and the eastern half of the Dawson Road Lots. Isolated anomalies occur at the western end of the Dawson Road Lots (sample 287) and southern Ware Township (sample 111) with elevated values in northeastern Adrian, northern Conmee and northern Oliver townships. Anomalous Cd concentrations were obtained from 3 till samples in southwestern Conmee Township (Figure 29, Anomaly D). This anomaly is coincident with the Ni-Cr-Co anomaly discussed earlier. Sam- ple 238 in south-central Adrian Township returned anomalous Cd concentrations in addition to the previously mentioned Au and chromite grains. Anomalous concentrations of Zn and Cu were also obtained from Superior lobe tills in the extreme southeastern corner of the study area. This area also contained anomalous levels of As and Ni. This anomaly is attributed to the widespread occurrence of Logan diabase. Float Mineralized float was encountered frequently during the course of the mapping and sampling program. Samples from many of these float clasts and boulders were collected and submitted for assay. Figure 30 shows the locations of these samples. Appendices F and G contain descriptions of the float boulders and

38 39 40 41 42 43 44 45 their geochemical data, respectively. Four samples returned anomalous assay results. One of these (5006) is a reanalysis of a sample of the Stares float in Aldina Township. Two new important base metal float discoveries were made as part of the sampling program. Of particular interest was the discovery of several large boulders of sulphidized iron formation within a gravel pit in Conmee Township, on the west side of Highway 11/17, 600 m north of the 3rd Concession (Figure 30, sample 5003). One of the boulders measured over 1 m in diameter and consisted of massive pyrite and magnetite with 10 to 15% sphalerite disseminated in pyrite-rich sections. Sphalerite was also concentrated along fractures and adjacent to quartz veinlets throughout the rock. Nodules of pyrite up to 1 to 2 cm in diameter were observed in some of the finer-grained zones of the rock suggesting a primary rather than secondary origin for the pyrite. Two samples from the pyrite-rich zones returned values of: 1) 5.13% Zn, 18 ppm Cu, 19 ppm Pb, 260 ppb Au and 0.5 ppm Ag; and 2) 2.85% Zn, 16 ppm Cu, 20 ppm Pb, 245 ppb Au and 0.5 ppm Ag. A sample from the magnetite-rich zone returned values of 850 ppm Zn, 25 ppm Cu, 5 ppm Pb, 25 ppb Au and <0.2 ppm Ag. A second sulphidized iron formation boulder from the same pit, measuring approximately 0.5 m in diameter and consisting almost exclusively of pyrite, returned values of 140 ppm Zn, 8 ppm Cu, 11 ppm Pb, 710 ppb Au and <0.2 ppm Ag. The boulders were found in a deposit of ice-contact stratified drift derived from the Superior lobe. Striae in the immediate vicinity of the pit are oriented at 320 to 330 Az. Assuming that the boulders are derived from an Archean source, it may be that the boulders were either eroded from a source less than 3 km southeast of the pit (i.e., Proterozoic rocks are present beyond this point) or that the boulders were initially eroded from a source north-northeast of the pit by “Patrician” (northern) ice then remobilized by the Superior lobe. Exploration work during the early 1900s along the lower reaches of Brule Creek, 4 to 5 km north- northeast of the gravel pit, by B.L. Morrison, the Davis Sulphur Company and General Chemical Company resulted in the discovery of “seven lenticular masses of brecciated, banded iron formation, in which pyrite has replaced a considerable part of the rock” (Carter 1990b). The largest of these masses has a maximum width of 23 m and is 244 m long. Other discoveries include a 21 m wide body of pyrite containing magnetite and pyrrhotite and a 9 m wide by 15 m long zone of magnetite-pyrite-jasper ironstone. It is possible that the boulders found within the gravel pit were derived from this area and that sphalerite was not recognized in the rock. It is not yet clear whether the sulphides indicate proximity to a VMS style zone of mineralization. Further work is required to assess the mineral potential of this area. A second boulder (Figure 30, sample 5004) interpreted to be a siliceous, argillaceous metasedimentary rock containing up to 50 to 60% disseminated and nodular pyrite was recovered from west-central Conmee Township in an area where abundant gabbroic rocks have been mapped (Carter 1990b). The float was collected from a deposit of northern derived boulder gravel in an area of variable overburden cover. The float returned anomalous concentrations of Cu (3075 ppm) and Co (1110 ppm) and negligible Zn (120 ppm). An evaluation of existing geophysical data followed by local prospecting is recommended to further evaluate the significance of this float occurrence. Several boulders of iron carbonate altered float were recovered from a sand and gravel pit located on the south side of Highway 11/17 at the west end of Dawson Road Lots (Concession A, Lots 76 and 77) (Figure 30, samples 5008 and 5009) . The sand and gravel pit is cut into an esker that can be traced greater than 2 km northward beyond the Quetico-Wawa subprovince boundary. A gravel pit cut into the same esker north of this boundary lacks any iron carbonate altered clasts. A source for the altered boulders is therefore probably located somewhere between Highway 11/17 and the contact with the Quetico subprovince. One of the boulders (5009), consisting of a very fine-grained, aphanitic, carbonatized, felsic/siliceous rock containing veinlets of quartz and potassic feldspar, minor carbonate in the wall rock and 5 to 10% fine to medium grained euhedral to subhedral pyrite, returned a Au value of 4540 ppb (0.13 oz/ton). A second maroon-coloured, carbonatized boulder (5008) of syenitic aphinity (lamprophyre) containing 5% finely disseminated pyrite concentrated on fracture surfaces returned undetectable gold (<5 ppb). Similar source rocks occur to the northeast at the Sheppard Zone where Au intersections of up to 1.6 g/t over 7.9 m have been reported (C. Bishop, Freewest Resources, personal communication 1998). Follow-up work is recommended within this patented parcel of land between the Shephard Zone and the Oskondaga River. Addi- tional boulder tracing may help to further refine the possible sources for the boulders.

46 47 Summary of Anomalies The current study clearly defines a number of precious and base metal exploration targets within the eastern half of the Shebandowan greenstone belt that require follow-up work (Figure 31). Most of the anomalous areas are defined by strong geochemical compositional signatures in till which may or may not be con- firmed by the humus geochemistry. A number of exploration targets are defined solely by the humus geochemistry. These anomalies are still considered significant and should be followed up with additional field investigations. Anomalous levels of Au and base metals in float boulders discovered as part of the field program also provide valuable information on the potential of local bedrock sources. The primary Au targets identified are situated: 1) at the west end of the Dawson Road Lots and the northwestern and northeastern corners of Horne and Laurie townships, respectively (Anomaly A); 2) along the southeastern corner of the Tower Syenite Stock in northern Conmee Township (Anomaly B) where few known Au occurrences occur; 3) in the Binabick Lake-Thunder Lake-Gold Lake area of central Conmee Township (Anomaly C); 4) in the northeastern corner of Aldina Township (Anomaly D) ; and 5) in central Aldina Township south of the Boreal Road (Anomaly E). Isolated Au targets are situated in western Adrian and Horne townships, eastern Sackville Township and south-central Blackwell Township. Ni-Cr-Co exploration should be focussed within eastern Adrian and western Conmee townships where large areas of mafic and ultramafic intrusive rocks have been identified (Anomaly F). Special emphasis is placed on the occurrence of large numbers of chromite grains in till samples collected over and down ice from this area. Ni-Cr-Co geochemistry clearly defined the position of mafic and ultramafic extrusive rocks at the west end of the Dawson Road Lots (Anomaly G). Gold mineralization appears to be closely associated with these ultramafics rocks. Similar geochemical signatures elsewhere may help to target other exploration programs looking for similar styles of mineralization. Till samples collected over mafic sills in the southeastern corner of the study area (Anomaly H) returned anomalous concentrations of not only Ni, but As, Sb, Cu and Zn. It is not clear whether this is simply a lithologic response or one that is a genuine response to mineralization. Field investigation within this area may be warranted. Isolated anomalies of Cr and/or Co within other areas may warrant follow-up work. Base metal targets defined by anomalous concentrations of Cu, Zn or Cd are widely scattered throughout the study area. Elevated base metals in till and/or humus occur within Adrian, Conmee, northern Aldi- na and Marks and eastern Sackville townships. Exploration efforts for base metals should be focussed within these regions. Notable anomalies are situated: 1) in northeastern Aldina Township, in the immediate vicinity of the Stares base metal float discovery, where several till samples returned anomalous concentrations of Zn or Cd (Anomaly I); 2) in northwestern Marks Township where several humus samples and a single till sample returned extremely anomalous Zn geochemistry (Anomaly J); 3) in northeastern and east- central Adrian Township where several humus and till samples yielded anomalous Zn levels (Anomaly K); and 4) in northwestern Adrian Township, where 2 till samples returned anomalous Zn values (Anomaly L). Many isolated anomalies of Cu, Zn or Cd occur throughout the study area as well and require additional work.
