Three properties: Jenny Leigh, Hay Island and Scotty Island were examined on Lake of the Woods. There are a large number of gold showings and current interest is generally the result of spillover from Nuinsco©s discovery of about l million tons, grading 0.20 oz/ton gold in the Cameron Lake area, about 50 km to southeast. A total of 40 man days were spent on geological mapping, sampling and report preparation on the three properties by Ulrich Kretschmar in August and September.
There is a close similarity between the geology of the Jenny Leigh property and the adjacent Wendigo Mine where about 200,000 tons grading 0.33 oz/ton gold and 9.2X copper were produced during 1900-195}.. The value of this production would be about $30 million dollars at current metal prices.
Major lithologies consist of mafic volcanics and interbedded differentiated ultramafic flows of probably komatiitic affinity. These are folded in a series of tight isoclinal drag folds on the Wendigo property and the mine horizon is repeated by a major east-west trending syncline on the Jenny-Leigh property. Mineralization on both the Jenny-Leigh property and at the Wendigo Mine occurs in gold-bearing conformable siliceous, locally graphitic interflow sediments. Associated sulfides are mainly chalcopyrite and minor pyrrhotite and pyrite. Two separate horizons have been identified on the Jenny-Leigh property and the potential for the occurrence of others is excellent. The best assay obtained from the stratiform mineralization is 0.15 oz/ton gold over 50 cm.
A two stage program is recommended. Initial work is to consist of line-cutting, remapping, stripping, trenching and an I.P. survey. If results of this program warrant it, a 3000 ft. drill program is proposed.
On the Hay Island property, fine-grained arsenopyrite and quartz occur as a matrix to a mafic volcanic breccia. Grab samples of the best mineralization gave 0.021 and 0.027 oz/ton gold.
On Scotty Island, a 55 ft. shaft is sunk in green chloritic lapilli tuff, about 30 ft. from a quartz vein. No significant results were obtained.
No further work is recommended for the Hay Island and Scotty Island properties.

INTRODUCTION
Three properties: Jenny Leigh, Hay Island and Scotty Island, were examined on Lake of the Woods, an area that has seen sporadic exploration and mining of gold since 1868. There are a large number of gold showings and current interest is generally a result of spillover from Nuinsco©s discovery of about l million tons, grading 0.20 oz./ton in the Cameron Lake area, about 50 km. to the SE. Gold mines that are in a similar geologic setting to the Jenny Leigh are, Consolidated Professor, Shoal Lake (currently producing), Sultana and Wendigo, both on Lake of the Woods.
Topography on the Jenny Leigh property is variable. The northern part which has been logged and which is underlain by basalt and differentiated flows forms a topographic high. Olivine-rich rocks and andesite weather low.
WORK ACCOMPLISHED
This is a summary report on geological mapping and sampling carried out by Ulrich Kretschmar and Patrick Chevalier in August and September on the Jenny-Leigh, Scotty Island and Hay Island properties in the Lake of the Woods. A total of 40 man days were spent by Ulrich Kretschmar on all three properties. The work consisted of geological mapping, locating claim posts, sampling of mineralized showings and examining nearby occurrences (Stella, Witch Bay, Wendigo Mine). Two days were spent on each of Scotty and Hay Island examining shoreline exposures, mapping outcrops and examining mineralization and workings.

DISCUSSION AND CONCLUSIONS
Jenny-Leigh Property There is a close similarity between the geology of the Jenny Leigh property and the adjacent Wendigo Mine. Top determinations using differ entiation trends in flows permits delineation of complex isoclinal folds, which in turn shows that the Wendigo Mine stratigraphy has been repeated by a major syncline and occurs on the Jenny Leigh claims. Two and possibly three mineralized sedimentary interflow horizons have been located on the north limb of the syncline. These should also occur on the south limb.
Current market value of the Wendigo production (about 200,000 tons grading 0.33 oz/ton gold and 9 .27, Cu during 1900-1951 and calculated at about $350 US/02, gold and $l US = $1.25 Canadian) is about $30 million Canadian. Assuming that mineralization of approximately the same grade and tonnage can be found, $30 million provides an estimate of the value of the target being sought on the Jenny Leigh property.
Hay Island Grab assays from what appears to be the best mineralization gave 0.021 and 0.027 oz/ton Au respectively. These assay results do not warrant further follow-up.
Scotty Island Three factors suggest no further work is necessary: 1. Assays are low. 2. The Scotty Island "mine" shaft is not on the claim group and 3. The shore line of Scotty Island is lined by cottages, the closest one being 550 ft. from the shaft.

RECOMMENDATIONS
Jenny-Leigh Property
1. Cut lines on the Jenny-Leigh property at 150 ft. spacing (in between the existing 300 ft. lines) in the area bounded by L15W/6S, 15W/27S and L15E/6S, L15E/27S. (Total of 2.75 line-miles). Establish pickets at 25 ft. intervals.
2. Rechain existing lines in the new grid area.
3. Remap entire area covered by new grid at a scale of l in. = 150 ft. Map in location of trenches more accurately.
4. Clean out and freshen all trenches at Showings l to 4 and collect assay samples across widths. Strip the area around Showing No. 2 by bulldozer and backhoe. Panel sample the vein exposed in the Stella adit to get an idea of the variability of the mineralization.
5. Do IP survey using 100 ft. spacing of electrodes.
6. Drill off mineralized horizons, contingent on results of the above work. An estimated budget for this program is presented below.
Hay Island and Scotty Island Properties
No further work is recommended.

LOCATION AND ACCESS
A location map showing all three properties is presented as Fig. 1. The Scotty Island and East Bay - Hay Island properties are approximately 10 km and 15 km respectively from Kenora and are best reached by boat. The Jenny Leigh property is accessible via the spur road to the east end of Witch Bay from Highway 71. From this road, there is a trail to the old Wendigo Mine site from whence the property is reached by traversing around the east end of Lac La Belle.
LAND STATUS
All three claim groups were staked in June 1983. A list of claims comprising the three properties is presented as Table l and Claim Maps are Figs. 2 and 3.
HISTORY OF EXPLORATION
Gold was first discovered in the district about 1873 and there was a major gold rush from 1885 to 1899. Subsequent exploration was characterized by erratic cycles of activity and inactivity. The latter were due to low gold prices, mismanagement of properties, small s ize o f the showings and territo rial disputes since the exact location of the Manitoba-Ontario border was not delineated. From a total recorded production of about 180,000 oz. in the Kenora-Fort Frances area, 75% came from thirteen mines in the Shoal L - Lake of the Woods area. The most important of these mines were Wendigo, Mikado and Sultana.
The Wendigo mine, located north of Witch Bay, Lake of the Woods, is directly adjacent to the Jenny Leigh property. Some aspects of its geology are discussed below. A complete history of mining in the Lake of the Woods is presented in Klondike at Home by Nelson et al (1976).

REGIONAL GEOLOGY
The properties examined lie in the Wabigoon Subprovince, a major subdivi sion of the Superior Province of the Canadian Shield. Supracrustal metavolcanic and metasedimentary successions occur as arcuate wedges at the margins of gneissic domes, and these are metamorphosed to assemblages charac teristic of greenschist and amphibolite facies. Patterns of metamorphism are closely related to the domes, such that the highest metamorphic grades occur adjacent to these structures. Late tectonic granitoid plutons, such as the Dryberry batholith and Viola Lake Stock, cut both the supracrustal and batholithic rocks. Internal shear zones, such as the Pipestone-Cameron Fault, involve the supracrustal assemblages and suggest late transcurrent movement (Blackburn & J anes, 1983).
The most recent geological map (Fig. 1) encompassing the area in which the Three Islands properties are located, is by Davies and Pryslak (1965). The Andrew Bay area including Hay Island and the Wendigo mine, is currently being remapped by Ayer (1984) and a preliminary map is shown as Fig. 4.
Scotty Island (Fig. 1) is entirely underlain by Archean volcanics (Unit 2A: rhyolitic and dacitic tuff, agglomerate and flows) except for its southern tip, where a Proterozoic diabase dike is shown. Units trend northeasterly, and dip steeply. Scotty Island may lie on the western limb of a regional anticline. The Scotty Island mineral occurrence is referred to below.
About 6 km to the northeast and along strike, are the Sultana and Ophir Mines on Sultana Island. About $l million worth of gold (at S327oz.?) was extracted from the Sultana mine during the period 1892-1934). Auriferous quartz veins occur at the contract of granite and porphyritic granite and "greenstone". The Ophir vein was entirely in unaltered granite porphyry and was a lobe consisting of a few lenses and bands of quartz separated by micaceous and chloritic material and granite porphyry. No production figures or years of operation could be located by the present author.
Hay Island is entirely underlain by basaltic and andesitic lavas. Units strike northeasterly and dip steeply. The trace of a major anticlinal axis

Two mineral occurrences are shown on ODM Map P281 near the Hay Island property. No information could be found on an antimony occurrence at the west end of Hay Island. On the other hand, the Hay Island or Keewatin occurrence at the north end of Hay Island consists of white quartz and carbonate as veins and bedded units in massive andesitic volcanics and tuff. Pyrite was the only sulfide seen, but chalcopyrite, galena, sphalerite and arsenopyrite are also reported. At the Hay Island occurrence, units strike 060 and dip steeply.
In the Witch Bay-Wendigo Mine area, interbedded basalts, porphyritic andesite and diorite flows or sills dip steeply and trend due easterly. The trace of a major anticlinal axis passes through Lac La Belle, so that the Wendigo Mine mineralized horizon is repeated on the Jenny-Leigh property.

PROPERTIES
JENNY-LEIGH
In the vicinity of Lac La Belle and the Wendigo mine, the major lithologies consist of mafic volcanics and differentiated mafic ultramafic flows of probable komatiitic affinity. ("Mafic intrusions" on Fig. 4). These are folded in a series of tight isoclinal drag folds in the area between Witch Bay and Lac La Belle.
Geology
Mapping was done on a grid, with 300 ft. line spacing. Three major units are exposed on the property: differentiated flows of probable komatiitic affinity, magnesian basalts and pillowed andesite or basalt flows (Fig. 5, in pocket). The differentiated flows (Units la, Ib, le) grade from a cumulate olivine-rich peridotitic base upwards into gabbroic or pyroxenitic units. These are in turn commonly overlain by leucogabbro, which is proportionately the most abundant rock type in the differentiated flows. Individual flows are commonly between 30-50 ft. thick. Thin polybrecciated flow tops and bases are common, and these are often talc-chlorite altered or carbonated.
A 750-1,000 ft. thick magnesian basalt sequence (Unit Id) also of probable komatiitic affinity, is intercalated with the komatiites. Small pillows with thin chilled margins and occasional polygonal breccia and pyroxene spinifex textures can be distinguished. The basalt is medium to fine grained, grey to dark green in colour, and generally hard and dense. Graphitic sulfidic interflow sediments are associated with this sequence, but do not outcrop (see Mineralization). The overlying flow or flows (Unit Id) is complex. At its western end, it thins - this is considered a p rimary (not tectonic) feature - and its upper margin is characterized by a talc-chlorite altered flow top breccia. At its eastern end, the flow consists of several thinner flows and irregularly intercalated magnesian basalt or rocks of pyroxenitic composition. The rocks of Unit 2, predominantly "andesite", are generally softer, more chloritic, and dominated by brecciated pillows and flow breccias. Interstices are commonly calcite-filled. Minor gabbro basalt flows
DIANNE 4 ULRICH KRETSCHMAR Geologists R.R.*1, Severn Bridge, Ontario. POE 1NO, Canada (705)689-6431 Page 13
and variolitic and feldspar porphyritic phases can also be distinguished but have not been traced. Mineralized interflow sediments are common in this sequence (Showings No. l, No. 2, see below).
Structure
The axis of a major regional syncline trends northeasterly through Unit 2. Facing directions are based on differentiation trends in differentiated flows of Unit 1. These show a reversal in the southern part of the property and on the adjacent Wendigo property. The location of the axis is based on symmetry. Independent evidence for this structure was found by Ayer during his mapping on the western shore of Lac La Belle and in Andrew Bay (Fig. 4).
The most important implication of the complex structure in this area is that the Wendigo Mine stratigraphy is repeated by the folding and occurs on the Jenny Leigh claims.
Geophysics
Geophysical surveys available consist of a regional compilation map (OGS P2044) that shows the axes of horizontal loop EM, airborne EM and ground mag surveys. In 1984 a ground VLF and magnetometer survey was carried out on the property. The results are presented in a report by Rejean Gosselin (1984) The axis of major conductors and magnetic highs are shown on Figure 5 (in pocket). The main results and interpretation follows: 42 VLF conductors were found. The majority are weak and are underlain by faults, swamps, groundwater, etc. and therefore are not considered to be significant. There are two major VLF conductors that appear to be geologically significant. Both of these were previously known and drilled by Dome in 1973 (Fig. 5). Conductive interflow sediments containing pyrrhotite and graphite were intersected. The axes of magnetic highs can be directly correlated with the basal cumulate olivine and magnetite-rich portions of differentiated flows. Major VLF conductors and magnetic highs are shown on the geological map (Fig. 5).

Mineralization There are four main showings on the Jenny Leigh property. Assay and rock geochemical results from these showings are presented in Tables l and 2.
Showing No. l Pods of massive pyrrhotite with minor pyrite occur in silicified andesite or gabbro. Rock geochemical results (Table 3) show slightly elevated concen trations of copper, but no significant gold.
Showing No. 2 Two or three distinct siliceous interflow sediments occur in this area. On the shore of Lac La Belle and in the trenches on L6W/18S, pyrrhotite, pyrite and graphite occur in a grey siliceous metavolcanic. Outcrop is scarce, but andesite and andesite flow breccia with interstitial carbonate appear to be the host rock. Rock geochemical results and assays of grab samples are presented in Tables 2 and 3. The most significant geochemical result is 5190 ppb (0.15 oz/t Au) from sample JL520. (Table 2, Fig. 6). Samples JL600, 601 and 602 were collected from the same trenches (Table 3) but the high result could not be duplicated. Two reassays of sample JL520 also produced lower results (Table 3). A series of trenches were found on possibly a third mineralized horizon (samples JL606, 609), but insufficient work has been done to delineate it.
Showing No. 3 A series of trenches were found in an area underlain mainly by strongly carbonated andesite, veined with clear quartz up to l m thick and occasional minor disseminated pyrite. No significant results were obtained.
Showing No. 4 This consists of a shear zone or a fault, filled with a massive white 20 - 30 cm thick uartz vein. The host rock is leucogabbro and flow top breccia. The vein trends 140 - 160 0 , dips steeply and clearly cross cuts stratigraphy. Foliation parallels the quartz vein along the margins. Mineralization con sists of blebs of chalcopyrite, hematite and carbonate in a sugary aplitic quartz matrix. Chalcopyrite occurs as drops. Significant gold (up to 0.336 oz/ton, Table 2, 3) was obtained from grab samples. Despite this, the
DIANNE 4 ULRICH KRETSCHMAR Geologists R.R.* 1. Severn Bridge. Ontario. POE 1 NO, Canada (705)689-6431 Page 15 potential of this area is not considered very high because of the secondary, cross-cutting nature of the mineralization.
Stella Adit In the Stella adit a 3 - 4 foot thick cherty interflow sediment or quartz vein containing minor disseminated pyrite is exposed. Both footwall and hanging wall consist of basalt. Its strike and dip is 110/55 SW. It is exposed for 100 feet in the adit and can be traced discontinuously in a series of pits and shafts to the shore of Stella Lake, about 1000 ft. to the east, where the horizon appears to terminate against a granite contact. No samples were collected since there are numerous assays reported in the literature and in assessment files. As well only a short section of the mineralized horizon which terminates in a breccia zone at the west end of the adit is on the Jenny Leigh property. A 60 ft. length is reported to show from 0.02 to 6.92 oz/ton gold over widths of l to 3 feet.

Wendigo Mine The Wendigo Mine was in operation from 1900-1951, during which time 206,054 tons averaging 0.33 oz/ton gold, 0.07 oz/ton silver and 9.2% copper were mined from "a shear zone in basalt that contained up to 50% pyrite, pyrrhotite and chalcopyrite" (MNR, MOIR, SMDR 001350). Cross sections and geological plans in the assessment files show that the mineralization occurred in three or more distinct horizons ("veins") that were conformable to diorite - andesite contacts and that they occurred within pillowed andesites of Unit 2. "Diorite" was the designation for flows of Unit 1. The ore has the appear ance of sheared Cu-rich siliceous massive sulfide. My interpretation is that the mineralized horizons are siliceous chalcopyrite, pyrrhotite-rich interflow sediments with a high gold content.

HAY ISLAND PROPERTY The location and general geology of the Hay Island property is shown on Fig. 1.
Geology Fig. 7 shows two mappable units: mafic volcanics (Unit 1A) and medium grained diorite (Unit IB). These trend northwesterly and dip steeply. Several independent determinations from pillows, gave tops to the southeast Unit 1A consists of mainly pillowed andesite or basalt. Pillows are up to l m in long dimensions, are generally poorly formed and commonly fragmented and fractured. Pillow selvages are chloritic and interpillow material consists of quartz, carbonate, chlorite, magnetite and occasionally epidote. Flow breccia was also noted. Massive andesite is less common.
Unit IB is medium to coarse grained diorite. About 10!? dark green pyroxene phenocrysts occur in a fine grained green quartzofeldspathic groundmass with hornblende and chlorite. The rock is massive, dark green in colour and has a smooth light brown weathered surface. The diorite may be a tholeiitic sill with a bulk chemical composition similar to Unit 1A.
The orientation of a probable axial plane cleavage is consistently 060 to 070 with dips steeply north or vertically.

Mineralization
The George Heenan occurrence on claim 727113 consists of a breccia zone in pillowed mafic volcanics. Calcite, quartz and arsenopyrite occur as cement, interstitially to angular to slightly foliated, chloritic volcanic rock of intermediate composition (Unit 1A, Fig. 7). The zone has been traced from the shore for several hundred feet inland in a series of trenches and a 65© deep shaft. The arsenopyrite is very fine grained and displays a few well terminated crystals at the edge of solid masses of the mineral. Visible gold was reported by Heenan but none was found by us. Minor pyrrhotite, pyrite and possibly tourmaline are also present. The mineralized zone strikes approximately eastward, and dips steeply to the north. Assays are presented in Table 4.
Pillowed volcanics striking 020 to 030 are exposed near one of the trenches, but tops could not be determined.
No other mineralization was found on the property.

SCOTTY ISLAND PROPERTY
The claims are underlain by a north-east trending, steeply dipping sequence of intermediate volcanics consisting mainly of andesitic or dacitic tuff, lapilli tuff and pyroclastic breccia (Fig. 8). Tuffs are chloritic and well foliated. Lapilli tuffs consist of subangular light-coloured fragments, 2-64 mm in size in a finer grained greenish grey matrix. Fragments are commonly feldspar porphyritic or scoriaceous. Lapilli breccia is well exposed on the west side of Scotty Island. Bomb-sized angular fragments occur in a lappilistone matrix. Fragments are largely feldspar porphyritic and have intermediate to basic compositions. Thin (about 5 cm) chert or cherty rhyolite beds were seen in outcrops on claim 727123.
Size gradation of fragments indicates a syncline with steeply dipping limbs and a northeasterly-trending curved axis in the southeast corner of the claim group.
A pit was found on claim 717123 and a 55 ft. deep shaft is located just along strike to the northeast (Fig. 8), The shaft is sunk in green chloritic lapilli tuff about 30 ft. north of a northeast striking white quartz vein, l - 2 ft. thick. Two samples of the best material were assayed and values are reported in Table 5. No assays are reported in the literature.
