A. List of Whole Rock and Metal Analysis Samples SUMMARY
During ten days of July, 1989, a four man crew attempted to map the Urban Claims of Minnova Inc., located in Urban Township. The lower group of thirty claims was entirely covered on foot before the project had to be terminated due to budget restraints. Only six outcrops were located within these thirty claims and thus, little geological data was collected.
The property is believed to possess a great deal of potential because of its location astride the northeast-trending Milner Shear which is the locus of six spectacular gold showings.
This report deals only with the southern group of thirty claims. It is intended that the mapping of the northern claims will be completed during 1990. In addition, a geophysical compilation of the Urban claims and surrounding properties will be undertaken. Upon the completion of these two projects, an overburden or diamond drill proposal will be prepared. 1
1.0 INTRODUCTION
This report describes the results of a 10 day mapping program which was carried out on the Urban Claims of Minnova Inc. The claims are located in Urban Township, in northwestern Quebec.
The report is necessarily brief since only nine outcrops were located.
2.0 LOCATION AND ACCESS
The Urban group of claims is situated in the extreme west-central part of Urban Township approximately 100 kilometers south-southwest of Chapais and 100 kilometers east of Quevillon, in the province of Quebec (Figure 1). The Urban group is centered at 49 d. 06 min North Latitude and 75 d. 43 min W longitude, within NTS map area 32 G/4. Its position relative to the other Minnova projects within Urban and Barry Townships is shown on Figure 2.
There are no roads into this area save for an old winter road from the Panache River to the west. The bridge over the Panache River, off Domtar road 463, no longer exists. Access to the property has been by float-equipped single Otter or Beaver, from Chibougamau to the Macho River, which takes approximately 40 minutes for a one-way flight. There are no lakes within the Urban Claims' boundaries.
The 1989 mapping crew worked out of an old camp situated next to the Macho River. From here, access to the Urban claims was gained by a short canoe trip to the end of the river. This camp was serviced by single Otter and Beaver aircraft of Propair in Chibougamau.
3.0 PHYSIOGRAPHY
The Urban claims lack any known outstanding physiographic features. The topography, as known, is flat, swampy and marked by clusters of thin spruce and tamarack. It was confirmed during the summer's mapping that outcrops are rare, suggesting that the overburden is probably deep in most places. Overburden depths encountered during the drilling of three holes in the north central part of the property were 15 ft., 63 ft., and 189 ft. (Fraser, 1986).
There are no large lakes, near to, or on the property, save for Lac Windfall, just east of the northeast end of the group ( Figure 2 ).

4.0 LAND POSITION
The Urban claims total 168 claims, occupying 2560 hectares in the west central part of Urban Township. One hundred and thirty-eight claims form a staggered block, five claims deep, between the township boundary on the west and Lac Windfall on the east. From the south edge of this block, thirty claims, in a group four claims wide, extend to a point just east and south of the north end of the Macho River ( Figure 3 ).
The Urban claims were initially staked for two reasons:
A. To control the northern extension of the north-trending, mineralized Milner Shear which hosts numerous gold showings, known since the 1940's, and
B. To control an east-west trending sediment/volcanic contact on both limbs of a major fold indicated, by magnetic surveys, regional geological maps, and a compilation of previous regional work.
5.0 PREVIOUS WORK
The locus of past exploration relevant to the Urban Claim block was the area along both sides of the Macho River, immediately south of the Minnova Urban Group, within Urban Township ( Figure 4 ).
In 1939, the region was mapped by R.L. Milner of the Quebec Department of mines on the Barry Lake Sheet. Milner reported on gold showings in an area which was underlain by basic and intermediate volcanics. These were caught up in an open anticlinal fold, the axis of which crossed the Macho River near its northern extremity. In addition to the folding, deformation was evident in shear zones which strike between 045 and 075. These are reflected in the lineation of topographic features such as lakes and rivers ( Milner, 1943 ).
In 1947, 38 claims were staked for the Quebec Smelting and Refining Corporation which established a camp on the Macho River. By 1948, 2,155 feet of X-Ray drilling and 27,500 cu. ft. of trenching near the Panache River revealed massive andesites intruded by feldspar porphyry, younger diabase, and rare dykes of granite, presumed to originate in the Souart Stock to the southwest. Most important was the location and exposure of the strongly developed Milner Shear which trends 055 and is the host for numerous, irregular, narrow, quartz veinlets of limited length. These bear pyrite, chalcopyrite, and erratic gold values ranging from 0.14 to several ounces per ton.
Immediately to the south, six gold showings were located in the same shear zone by Macho River Gold Mines. Work was suspended on both properties in 1949 due to the low price of gold.

From 1953 until 1961, both properties were combined in an option agreement between Aumacho River Mines ( formerly Macho River Mines) and Quebec Smelting and Refining Ltd. ( formerly QSR Corp.) Subsequent resistivity, electromagnetic and magnetic surveying resulted in the discovery of up to four more Au showings associated with magnetic highs in the Milner Shear.
In 1961, Monitor Securities optioned the property and completed 65,000 feet of drilling, 33 miles of ground magnetometer surveying, and an EM airborne survey. All of this work did not define either significant new mineralization or extend the dimensions of known showings.
Since 1961, pieces of this area around the Macho River have been offered for option to Kerr Addison (1964), were held by Shell Minerals in 1978, Jean Alix and B. C. Salamis in 1980, and Kidd Creek in 1984. The showings areas are currently held by a Falconbridge/Beaufield Resources Joint Venture, Cominco Ltd., and by the Urbana Corporation.
A 1988 compilation plan by Greenstone Resources shows that spectacular intersections have been encountered in holes drilled into the Milner Shear Zone. These include 87 g/T Ag and 2.27 % Cu over 9.0 m, 1.09 opt Au over 8.5 ft, 3.48 opt Au over 2.08 ft and 12.6 opt Au over 7.0 feet.
Within the Minnova Urban block of claims, 10 claims were staked on speculation by Fab Metal Mines, due to the Macho River activity to the south. As far as is known, approximately three holes were drilled in which the highest gold value obtained was in the .05 opt range.
6.0 GEOLOGY
6.1 Regional Geology
Urban Township is situated over a small greenstone belt which is within the extensive Abitibi Greenstone Belt which extends across portions of northeastern Ontario and northwestern Quebec ( Figure 5 ). To the east, the Abitibi is bounded by the northeasterly-trending, crystalline rocks of the Grenville Province and to the west by the Kapuskasing Sub-province. The rocks of the Abitibi Belt are Precambrian in age and are predominantly east-west trending, metavolcanic and metasedimentary rocks, which have been metamorphosed to greenschist facies. Intruding all supracrustal rocks are both syn and post-tectonic felsic and mafic intrusive rocks.
The smaller, subordinate greenstone belt, underlying the Urban area, extends from Carpiquet Township in the west, through Urban and Barry Townships, and eastward to Buteaux Township. From north to south, the belt varies from 5 to 12 km wide and is bounded by younger granitic rocks. The Grenville front is about 30 km away to the south.

The predominant volcanic rocks within this belt are southwest-facing basalt and andesitic lavas interbedded with argillite, arkose, conglomerate and magnetite and hematite- bearing sediments. Isolated piles of rhyolitic lavas and pyroclastic flows also occur within the volcanic sequence.
It is reported that Freeman (1943) and Milner (1943), defined a more sedimentary-dominant series of rocks in the north part of the belt and a volcanic-dominant series in the south.
While most of the rock has undergone greenschist facies metamorphism, amphibolite facies assemblages, expressed as garnetiferous horneblende and mica schists, are pronounced in the southeast, proximal to granitic gneisses.
Within the belt, structure is complex. This is the result of several phases of folding, faulting and deformation due to the intrusion of the bordering granitics which was followed by the Grenville Orogeny.
6.2 Property Geology
The Urban claim group is situated over a folded volcanic-sedimentary contact zone which extends from Carpiquet Township in the west , through Urban Township, to the Grenville Front, over a distance of 110 kilometers. The claims are underlain by a mixed sequence of mafic volcanic and sedimentary rocks, with intercalated graphitic horizons and sulphide iron formation. A strongly developed north-south trending shear or fault zone, called the Milner Shear bisects the claim group.
6.2.1 Lithologies
Only nine outcrops were located during the mapping. Of these, seven are outcrops of intermediate volcanics (V2), one is either intermediate or mafic volcanic, and the last is an outcrop of an intermediate intrusive and felsic volcanic ( Figure 6 ).
6.2.1.a Intermediate Rocks - V2
These rocks are pillowed andesites. They weather a grayish-green to dark green colour and on fresh surface they are medium-grayish to pale green. Because they are predominantly aphanitic, the composition is difficult to discern in the field. Minerals which were observed were abundant chlorite, lesser sericite, and from 5-10 % calcite.
Alteration which is present consists of weak to moderate carbonatization, weak to strong silicification and weak sericitization. 10
The only mineralization noted was pyrite in amounts from a trace to 1%. A trace of chalcopyrite was observed in one outcrop. mineralisation:
The most outstanding feature of most of the andesite outcrops are the pillow structures. These can be up to 50 cm long and are often slightly stretched into the prominent direction of foliation which is 250/60. The pillows are, for the most part, quite evident due to their dark rims, the pockets of quartz which are often seen in the triple junctions, and due to the vesicles near the pillow rims.
While most occurrences were positively identified as outcrop, several may be only large pieces of sub-crop.
6.2.1.b Intermediate or Mafic Volcanics - V2 or V3
One outcrop was located which could be either mafic or intermediate volcanic. The rock has a greenish weathered surface while on fresh surface the colour is medium to dark green. The grain size is very fine to aphanitic.
The minerals which could be identified are 1: chlorite which occurs as lenses, 2: 15-20 % calcite which is present as veinlets, as well as being part of the matrix, 3: minor magnetite, averaging 1mm in long dimension, and 4: sericite?
Only a trace of pyrite was noted.
This outcrop is weakly to strongly sheared to massive, and is well-pillowed in places. The pillows are stretched into the plane of the regional foliation which is 250/45.
6.2.1.c Felsic Volcanics - V1
One outcrop of felsic lava occurs between two small outcrops of an intermediate intrusive rock. The lava is massive, has a cream-coloured weathering surface, and is greyish-green on fresh surface. It is aphanitic and appears to have, as part of its composition, chlorite and a trace of calcite.
Alteration is evident in the form of strong silicification.
6.2.1.d Intermediate Intrusives - I2
The two outcrops of this rock type sandwich the felsic volcanic outcrop which was just described.
This massive rock has a greenish weathered appearance but is medium greyish green on fresh surface. It is very fine-grained and appears to be partially composed of chlorite, which occurs in crystals, in pockets and in veinlets, and from 2 to 20 % calcite. Fine feldspar crystals may be visible. In addition , there are veinlets of white quartz and calcite.
11
The only mineralization observed was a trace of cubic pyrite in places.
6.2.2 Structure
The scarce data suggests that there is a regional S1 foliation which trends between 050 and 070 and dips between 45 and 60 degrees to the north. This foliation is well developed in the andesites but is not so evident, seemingly, in the intrusive or felsic volcanic rocks.
One strongly developed 10 cm-wide shear was observed which was oriented at 080 with a 25 degree northerly dip.
7.0 GEOCHEMISTRY
Eight whole rock samples and four metal analysis samples were taken during the mapping program. The analyses are listed in Appendix 1 for both sample types. As well, the locations of the samples are presented on Figure 7.
Because the number of samples are so few, no conclusions can be drawn from their results. It remains to be seen how these results will compare to those of samples, taken during the 1990 mapping program, over the remainder of the property. .--
8.0 CONCLUSIONS
The conclusions to be drawn from this mapping program are obvious. That is, that there are very few outcrops to be seen and that more indirect methods of evaluating the property will have to be used.
However, this does not detract from the potential of the property. I believe that, underlying this group of claims is the Milner Shear which is host to spectacular gold showings, just to the south. In addition, there have been numerous, high-grade, but narrow, gold showings located on the properties contiguous to the Urban claims.
9.0 RECOMMENDATIONS
In view of the potential of the property and the lack of outcrop, I recommend the following work:
• 1. The abundant geophysical data available for this property should be evaluated and correlated.
2. The geophysical data for the surrounding properties, 00- especially the magnetic data, should be obtained, interpreted, and related to the Urban claims' geophysical data. This should be done, especially, to locate the Milner Shear which hosts gold showings with a strong magnetic signature. 12
3. The remainder of the property should be mapped, especially the east end where it is likely that the Milner Shear and the Windfall-Croft Lake Fault transect the property.
4. The existing diamond drill core for this property should be sampled for whole rock analysis since the core will likely prove the best source of lithological data. This is said in the expectation that outcrops will not be numerous in the presently unmapped part of the ground.
