than 10 per cent in the Iron Mask Hybrid unit. Weak to moderate propylitic alteration with attendant pyritization is quite pervasive throughout the Iron Mask Hybrid unit. In contrast, the Cherry Creek unit is pervasively saussuritized with local zones of propylitization, albitization and potassic feldspathization.
w
The extreme southwestern corner of the property is underlain by well- indurated, massive and bedded tuff, tuff breccia, and interbedded flows and flow breccia of the Upper Triassic Nicola Group; in apparent fault contact with the batholithic rocks of the Iron Mask Hybrid unit.
Immediately north of the Grandview Ski Hill, there is a small body of Sugarloaf unit hornblende-augite diorite while capping the hill itself are unaltered and unmineralized, Miocene-age olivine basaltic flows, flow breccias and intercalated tuffaceous beds unconformably overlie both the Iron Mask Hybrid and Cherry Creek units.
The 1989 percussion drilling program tested a property-wide geophysical anomaly within which copper mineralization was known to occur. The program included the drilling of forty-one ( 4 1 ) boreholes, totalling 11,506 feet (3,507.03 metres), and the analysis of 1,036 samples for their gold content and, in most cases, their copper content.
Several o f the percussion drill holes intersected low to sub-economic copper mineralization over narrow to quite significant thicknesses. Percussion drill hole PE 89 - 25 returned the longest intercept of the program, 294 feet ( 8 9 . 6 1 metres) grading 0 .077 per cent copper. The most significant and highest grade copper mineralization were both intersected by drill hole PE 89 - 21 , 251 feet (76.50 metres) grading 0.108 per cent copper which included a section grading 0 . 3 9 6 per cent copper over 10 feet (3.05 metres). The highest gold value was returned from drill hole PE 89 - 32, 855 p.p.b. over 10 feet.
The results from all of the drilling programs indicate that there i s not an obvious large, near-surface zone of copper mineralization with economic grades present on the property. Narrow, near-surface, high grade zones probably exist within the area of known mineralization but their tonnage potential is very limited given the extent and detail o f all of the exploration work.
It is the writer's opinion that further testing of the near-surface copper mineralization cannot be justified. There is, however, some geologic evidence that the known mineralization may be spatially associated with an easterly trending breccia structure(s) central to the property. This structure could conceivably host increased copper values beneath the limit of recent drilling; however, exploration of such a target could only be considered speculative.
RECOMMENDATIONS
No further near-surface exploration can be recommended. I f exploration does continue, it should be directed at evaluating the zone of known copper mineralization within the IM 59, 65 and 67 mineral claims for its depth extensions.
w Such a-program would necessitate diamond drilling.

occurs locally within the batholith but, according to Y.T.J. Kwong ( 1 9 8 7 ) , it may not be genetically related to the two major plutons.

On the southwestern flanks of the batholith, near the subject property, cola Group is comprised of well-indurated, massive and bedded tuff, tuff a, and interbedded flows and flow breccia. Along the northeast flank, less ndurated and altered tuff and tuff breccia prevail (Kwong, 1987) .
The various lithologic units of the Iron Mask and Cherry Creek plutons in composition and texture from coarse-grained gabbro to microsyenite; each dually distinguishable but all with an alkaline affinity. All the units
- two plutons, except possibly the Picrite unit, are interpreted to be the of th product of a single cycle of fractional crystallization from a common magma. They range from the agmatitic, gabbroic and dioritic o f the Iron Mask Hybrid and Pothook units, through the porphyritic dioritic rocks of the Sugarloaf unit, to the syenitic rocks of the Cherry Creek unit (Kwong, 1987) .
Major northwesterly, northerly and northeasterly trending, high-angle, recurrent faults have controlled the emplacement of the iron Mask batholith, its alteration and mineralization and the subsequent deposition of the Kamloops Group during Paleocene or Early Eocene time.
A1 1 of the batholithic rocks have undergone some degree of weak to moderate saussuritization, and locally some degree of propylitic alteration. Albitization and potassic feldspathization are more common with the Cherry Creek unit.
The Afton mine, with start-up reserves of 30.84 mi 1 1 ion tonnes grading 1 .OO per cent copper, 0 .58 gram per tonne gold and 4 . 1 9 grams per tonne silver, has dominated the metal production from the Iron Mask batholith. Other past producing mines include: the Iron Mask, Erin, Galaxy Copper, Python, Larsen, Iron Cap and Pothook; and more recently the Crescent Zone on the Comet property.
it is widely recognized that most of the known copper and precious-metal deposits are spatially and/or genetically associated with major structural features, such as: shear zones along intrusive contacts, brecciated zones within an intrusive phase, intersections of fault zones, oxidation, and/or unconformity exposures. Copper mineralization is commonly associated with zones of intense potassium feldspathization, albitization and carbonatization which, in turn, reflect concentrated hydrothermal activity within permeable structural features (Kwong, 1987) . I t is also recognized that a spatial association with basaltic rocks of the Picrite unit may be important chemically as a buffering agent to the metal-bearing hydrothermal fluids, causing the precipitation of sulphide mineralization. These picritic bodies occur dominantly within major fault structures, thus, supporting the exploration of major structural features.
It has also been noted by Kwong (1987) and other geologists familiar with the Iron Mask batholith and its associated mineralization, that most of the sub- economic and economic copper and precious metal occurrences are spatially, if not genetically, associated with the Sugarloaf and Cherry Creek units.

w 1989 PERCUSSION DRILL ING PROGRAM
1 1
The 1989 percussim drilling program was undertaken to evaluate a property- wide, induced polarization geophysical anomaly within which copper and precious- metal mineralization was known to occur. Cominco Ltd. contracted A1 Miller Percussion Drilling Ltd. of Barriere, B.C. to carry out the drilling using a truck-mounted drill rig; and Gallant Trucking Ltd. of Kamloops, B.C. to provide drilling water. Messrs. G. Graham and S. Balden, two employees of Cominco Ltd., were on site to provide supervisory and logistical support, including: locating, picketing and surveying drill sites; collecting, handling and delivering drill samples to the assay laboratory; and carrying out any reclamation work. Minorex Consulting Ltd. of Delta, B.C. was contracted to supervise the drilling program, log the percussion drill samples, and document the results of the program.
Between May 16th and June 5th, 1989, forty-one (41) boreholes, totalling 11,506 feet (3,507.03 metres), were drilled throughout the property at predetermined locations. Most of the boreholes were completed to a depth of 91.44 metres (300 feet); however, several had to be abandoned short o f their target depth due to caving within the hole, or water loss. See Figure 4 accompanying this report for the locations o f the drill holes.
Most of the predetermined drill sites were accessible by the truck-mounted drill rig and water truck. When a proposed site was found to be inaccessible it was moved to the nearest favourable location. During the program no heavy equipment was required to construct any access road or drill site.
Most of the drilling samples were collected at conventional ten-foot (3.048 metre) intervals. Usually the first sample of a drill hole was collected over an interval more than ten feet, but less than 20 feet, to allow for the placement of the splitter after the initial penetration of bedrock. The ten-foot samples were collected from the l/l2th cyclone splitter which was mounted on the drill collar and deposited directly into poly sample bags. A flocculating agent was added to the sample to settle the fine material and, later, the excess water was decanted when the sludge had settled.
Geologic chip samples were collected by sieving a sample from the reject side o f the cyclone splitter. A sieved sample from each ten-foot interval was placed directly into a plastic chip sample container for later microscopic examination and documentation. See Appendix 1 of this report for a geologic log of each drill hole.
Upon completion of each borehole, the split and bagged samples were delivered directly to Kamloops Research & Assay Laboratory Ltd. in Kamloops for analysis. A total of 1,036 samples were delivered, of which all were analyzed for their gold content and 989 were analyzed for their copper content. Most of the samples from the Miocene-age volcanic rocks were not analyzed for copper. See Appendices I I and I l l of this report for the analytical results and analytical procedures, respectively.
Upon the completion of the program a1 1 of the dri 1 1 sites and access routes were seeded with an upland grass seed mixture; thus, fulfilling all necessary reclamation requirements.
