V6C 1A5 February 15, 1989 SUMMARY Ashworth Explorations Limited carried out two field programs, consisting of geological mapping, rock sampling and soil sampling on the Bullet Claim Group during 1988. The Bullet Claim Group consists of four continguous mineral claims (51 units) located in the Clinton Mining Division, approximately 65 kilometres west- northwest of Clinton, B.C. Previous work includes a regional geochemical rock sampling survey performed for the B.C. Ministry of Energy, Mines and Petroleum Resources and two geological mapping, rock sampling, and stream sediment sampling programs completed in 1987 by Ashworth Explorations Limited. The 1987 geological mapping program confirmed the presence of Eocene volcanic rocks which correspond to the rock units described at the Blackdome Mine, located three kilometres west-northwest of the subject property. One rock sample collected during 1987 assayed 280 ppb Au. The 1988 exploration programs outlined one large area of mercury and gold anomalies in rocks, soils and stream sediments. Anomalous values in mercury were obtained from the rock sampling, with values up to 420 ppb. A second and third phase exploration program has been recommended. Phase I1 will consist of grid layout, soil sampling on the grid, geological mapping and rock sampling, at a total estimated cost of $42,000. Phase I11 is contingent upon targets being established from Phase 11. It would consist of additional fill-in soil sampling, hand trenching, blasting and backhoe trenching.

INTRODUCTION This report was prepared at the request of Clive Ashworth to describe and evaluate the results of a geochemical survey on April 21, 1988 and a geological- geochemical survey carried out from October 15 to 16, 1988 on the Bullet Claim Group, Black Dome Mountain area, B.C. The report also describes the regional geology and the past exploration activities in the area, and outlines a proposed exploration program. Mr. Leriche planned and supervised all fieldwork, and examined the subject claims on April 21, 1988. Mr. Yacoub was the project geologist on the subject claims from October 15 to 16, 1988. 2. LOCATION, ACCESS AND TOPOGRAPHY The Bullet Claim Group is located in the Camelsfoot Range on the Fraser Plateau approximately 65 kilometres west-northwest of Clinton, B.C. and approximately 54 kilometres northeast of the town of Goldbridge (Figure 1). The claims lie within NTS mapsheet 920/8 at latitude 51 18'N, longitude 122 26'W in the Clinton Mining Division. Access to the claims is via a gravel road which leads west from Highway 97 approximately 18 kilometres north of Clinton, to the Empire Valley Ranch. From the Empire Valley Ranch, the Blackdome Mine road and a forestry access road lead to the claims. Use of a four-wheel drive vehicle is recommended. 3 The terrain is characterized by gentle to moderate slopes descending into an east-west trending tributary of Porcupine Creek. Vegetation consists of fairly thick stands of pine and fir at lower elevations, with the higher ground and ridge crests more sparsely vegetated to barren. Elevation varies from 1140 metres on Porcupine Creek to 1692 metres in the northeast corner of the claims, giving a total relief of 552 metres. 3. PROPERTY STATUS The Bullet Claim Group consists of three contiguous four-post mineral claims and one two-post mineral claim, totalling 51 units. The claims were grouped on August 31, 1987. The claims are owned by Clive Ashworth of Vancouver, B.C. Pertinent claim data is as follows: CLAIM NAME RECORD NO.

AREA HISTORY BLACKDOME The first major find in the general area of the subject claims occurred in the late 1940's with the discovery of gold-bearing quartz veins in the Black Dome Mountain area, approximately three kilometres west of the western claim boundary of the Silver Bullet I1 claim. The following ten year period saw work 5 performed by Empire Valley Gold Mines Ltd. and Silver Standard Mines Ltd. including sampling, stripping, packsack drilling, trenching and the driving of two adits into the vein structures. By 1972 additional gold-bearing quartz veins had been located west of the original claims. In 1980, Blackdome Explorations Ltd. completed additional work including trenching, drilling and underground exploration. Mine construction began in 1985 with underground development of the Number 1 and 2 veins on two levels and a 200 ton-per-day mill. Production commenced on May 16, 1986. Reserves at December 31, 1987 were estimated at 245,615 tons with an average grade of 0.74 ounces of gold per ton and 2.15 ounces of silver per ton (Blackdome Mining Corporation Annual Report, 1987). The gold-bearing quartz veins at the Blackdome Mine are hosted by Eocene rhyolitic to andesitic volcanics which exhibit argillic wallrock alteration adjacent to the veins. A northeasterly trend is dominant in the structure, veins and host rocks. Northeast-trending normal faults cut the area and are believed to be related to movement along the Fraser Fault System during the Eocene epoch (Harrop & Scroggins, 1987). BOBCAT Immediately southwest of the Blackdome property, and approximately seven kilometres west of the southwest comer of the Lynx IV claim, lies the Bobcat Claim Group owned by Lexington Resources Ltd. 6 The Bobcat claims were originally staked in 1980 as the Pony claims and occupy the southwest extension of the same mineralized zone present on the Blackdome Mine property. Highly anomalous gold results were obtained from soil samples collected in 1982 near the northwest comer of the Pony claims. In 1986 the Pony claims lapsed and were restaked as Bobcat I, I1 and I11 claims and were subsequently sold to Lexington Resources Ltd. Between 1986 and the present, geological mapping, prospecting, geochemical soil sampling, geophysical surveys, trenching and diamond drilling have been performed on the claims with results showing good potential for finding epithermal Au-Ag mineralization similar to that at the Blackdome Mine. BALLATAR Ballatar Explorations Ltd. has optioned the EH1, EH3, EH5, EH6 and EH7 claims, located 6.75 kilometres west-southwest of the southwest comer of the Lynx IV claim. An airborne VLF-EM survey and reconnaissance geological mapping followed by mapping, soil and rock sampling and geophysical surveys have been performed on this property from 1984 to 1987. In 1988 a detailed soil sampling program was completed to be followed by trenching of soil anomalies and vein occurrences in October 1988. The soil sampling program returned values up to 790 ppb gold with additional results pending (Vancouver Stockwatch, November 7, ,' ,' 1988). Trenching and road building has uncovered additional altered shear zones in rocks believed to be stratigraphically equivalent to the host rocks at Blackdome Mine (Vancouver Stockwatch, November 7, 1988). 7 OTHER PROPERTIES The Lone claims are located approximately five kilometres east-southeast of the eastern claim boundary of the Lynx IV claim, near the confluence of Lone Cabin Creek and Fraser River. In 1983, MineQuest Exploration Associates Limited, on behalf of GoldQuest I, carried out a program of stream sediment and contour soil sampling. None of the samples were assayed for mercury and the highest result was 310 ppb Au from a soil sample (Ridley, 1984). The Pine claims are located .6 kilometres east of the east claim boundary of the Camelsfoot claim, along Lone Cabin Creek.
