REGIONAL GEOLOGY 8 2 1. SUMMARY The Coulonge River Property of Bryson Burke Resources Inc.. (referred to as BBR from here on) is located 75 km west of Maniwaki, Québec in Pontiac County. The property hosts a discovery of micro-diamonds found in the sediments of the Coulonge River as well as in some of the local streams in the Bryson Lake area. Glacial fluvial tills overlay the Grenville basement rocks or mainly granitic to mafic rich gneisses. The property is less than 200 km southeast of the Guigues kimberlite discovery. The property is comprised of 4686 mining claims in 29 separate non-contiguous claim blocks with a total area of over 76,000 hectares. Bryson-Burke Exploration Ltd.(BBE) carried out a regional grassroots exploration program during the period of June 1,1994 to December 31, 1995. The first phase consisted of completing orientation overburden trenches in the vicinity of the discovery of microdiamonds found in the sediments of the Coulonge River. With some understanding of the local till cover, comprised mainly of glacial/fluvial boulder outwash till overlying the Grenville Basement, a regional till sampling program was launched under the direction of Mousseau Tremblay and Ron Little. The till sampling program was to delineate any possible trains of kimberlite indicator minerals. Already there were possible targets outlined by ancient airborne geophysics with ground follow-up on 53 of the better targets. Any results from the till program were to assist in the prioritization for diamond drilling of these targets. This approach to delineation of targets dictates that the samples be taken at greater distances from the perceived targets in a down-ice direction. For this reason many of the samples were not actually on the staked claims although a reference can be found for each claim in the appendix for each sample. For this reason, the total expenditures for this program include the costs for all samples including those that were taken south of the respective claims. A total of 248 till samples which typically weighed 40 kg were processed to a concentrate using hand jigging and an INEX jig in the field. The concentrates were further reduced to a heavy concentrate using heavy liquids with a density of 3.33 g/ml. All samples were given a brief microscopic inspection and almost half were given a very detailed inspection including the microprobing of several grains. All results indicate that there were no true kimberlitic indicator minerals found in any of these inspections. Plans for more detailed till sampling were put on hold. - 4 2. INTRODUCTION This report briefly describes the summer and fall 1994 exploration program and its results on the Coulonge River Property with respect to the work performed as per an Exploration grant given to Bryson Burke Resources Inc. in 1994. No follow-up exploration program is proposed in this report. 3. LOCATION AND ACCESS 3.1 PROPERTY LOCATION The property is located in Pontiac County in the Lac Bryson Area of western Quebec. It is made up of 29 claim blocks lying between 46 and 47 north latitude and 7630' and 7730' west longitude (see Figure 1). The nearest town is Deep River, Ontario, on the Ontario-Quebec border, about 55 km southwest of the sampling sites. The small village of Otter Lake is located 66 km southeast of the property. 3.2 PROPERTY DESCRIPTION Ron Little has not independently verified title to any of the claims. The description of the claims has been derived from information provide by BBR. The property is owned 100 % by BBR. The property consists of 29 claim blocks comprising unpatented mining claims which cover approximately 76,000 hectares. The claims were staked by BBR from January 1993 to February 1994. The majority of the property is located within a Main Block which extends for about 35 km along the Coulonge River. The claim blocks are shown on the compilation map in the appendix. The list of claims can be found in the appendices of reports filed previously this year. BBR \\_ PROPERTY AREA Figure 1. Property location map. 6 3.3 ACCESS CLIMATE AND TERRAIN Access to the property is gained from the south, through the Zone Environmental Controlee (Z.E.C.) Pontiac. The southern boundary of the property can be reached from Ottawa in about three hours. The best route into the property is though Renfrew on Highway 17 West and across the Ottawa River. After crossing the river, Highway 301 North leads into the village of Otter Lake where the Picanoc Road is taken north, eventually turning into a moderately maintained logging road, that leads to the south end of the Z.E.C. Permission is necessary to use the logging roads in the Z.E.C. that access the property. From the control gate, a dirt logging road is followed north until a logging camp is reached on the east side of the river. A bridge spans the river at this point below a bend in the river known as the "Big D". The main sampling sites are in this area and to the north of the bridge. Access to most of the property is gained by the logging road. Many smaller hunting roads and trails allow good access to the rest of the property as well as the lakes and rivers. The area is roughly 350 m above sea level consisting of numerous rolling hills, abundant lakes and active drainage systems. The hills with an average relief of 75 m exhibit open deciduous to often dense boreal forests. Steep hills, tight bush and swampy areas are common and can create slow working conditions. 4. EXPLORATION HISTORY 4.1 GENERAL The area was not known to have been explored for diamonds until Bryson-Burke Resources discovered indicator minerals in panned concentrates around Lac Bryson in 1992. Regional radiometric, gravity and aeromagnetic data from the Geophysics Division of the GSC were used in conjunction with aerial photography to define targets for claim staking. This area has been previously explored for base metals such as copper, zinc and nickel. There has been some interest in gold and silver and there are several current operations producing industrial minerals such as marble, mica and quartz. The historical geological maps are at to large of a scale to be of much use. 7 4.2 GEOPHYSICS The airborne magnetic survey with resultant total field and vertical components as calculated and published in false colour by the GSC were useful in identifying positive circular anomalies that are as large in diameter as the line spacing (800 m or greater). Smaller anomalies appear only if a the flight line passed exactly over the target. Despite its limited application, the survey was useful for recognizing regional structures and faults. In an attempt to gain additional information, the magnetic data was processed by BBE to enhance potentially significant anomalies. Having first been reduced-to-pole, a high pass filter was applied to enhance the smaller/tighter elliptical anomalies, that may indicate kimberlite pipes, from the larger anomalous lows generated by the gneissic host rock. Euler deconvolutions were computed, and all vertical pipe-like structures were filtered out as potential targets to be compared with other data information. 5. GEOLOGY 5.1 REGIONAL GEOLOGY The property lies within the Saint Patrice Lake area and is underlain by Precambrian rocks of the Grenville Group. These rocks consist of quartz-feldspar gneisses, amphibolites, hornblende gneisses, biotite gneisses, garnet gneisses and metasedimentary formations with a characteristic marble member. The quartz-feldspar gneisses occur in association with all the gneisses in the area and make up a large region around Lynch Lake, where they form the core of an antiform structure that plunges southeast. Biotite gneisses are the most common, and in places contain abundant hypersthene, characteristic of charnockitic affinities (usually indicating a granulite facies terrain). Garnet gneisses are found in the biotite and hornblende gneiss terrains and serve as marker beds to outline the antiform structure. Marble is found mainly in close proximity to the Coulonge River. Two types (and ages) of intrusions into the Grenville Group exist in the region, namely Precambrian pre- and post-tectonic intrusions. The pre-tectonic intrusions are of gabbroic, pyroxenitic or basaltic composition. These make up an insignificant portion of the rocks exposed in the area, but merit attention. The post-tectonic intrusions consist of small massive granite and syenite bodies, pegmatites and aplites. Younger diabase dykes and associated gabbro bodies are also found throughout the region (Katz 1976).
