SUMMARY Exploration on the Regis mineral claims in the Copper River area during 2004 comprised prospecting, grid preparation and soil sampling. This work was mainly directed to hrther the exploration of areas in which reconnaissance geochemical sampling had returned anomalous amounts of precious and base metals in soils overlying felsic volcanic rocks of the Hazelton Group. A copper occurrence was discovered on the southern slopes of the south end Ashman Ridge. Anomalous geochemical results were obtained for gold, silver and some base metals in a few localities. INTRODUCTION Regis Plante conducted a prospecting and geochemical program on the Regis and Regis 3 mineral claims in May and July, 2004. I was retained by him to offer suggestions and to review this work and to prepare an assessment report. I visited the property on 6 July this year and joined him in examining parts of the northern claims area. DISCLAIMER The prospecting and geochemical sampling were done by Regis Plante and an experienced crew, who also prepared the source maps. One of the crew members, Paul Charbonneau, has completed a prospecting course presented by Dr Tom Richards. Although I was not in the field when the geochemical samples were collected, I briefed the crew beforehand and later saw some of the soil sample sites. The work was apparently conducted in accordance with generally good exploration practice but I disclaim responsibility for the work. LOCATION AND ACCESS The centre of the Regis claims group is at approximately 54" 49' north latitude and 27" 5 ' west longitude, about 44 km west of Smithers, Omineca Mining Division, British Columbia, NTS Map 93L/3 or 93L.08 (Figure ). The McDonell Lake Forest Service Road provides good summer access to the claims. Winter road access is dependent upon logging activities. The road distance to the centre of the claims from Smithers is about 58 km. The claims are mostly free of snow from June until October. PHYSIOGRAPHY AND VEGETATION The claims cover part of the southern slopes of the southern end of Ashman Ridge and extend southward down to the Zymoetz (Copper) River. The claims area ranges in elevation from about 760 m on the ridge to 750 m near the river. Slopes are gentle to steep and there are local cliffs. The middle and lower slopes support stands of fir and hemlock trees. There are several logged areas on the lower claims. The claims are mostly in the Moore Creek drainage system, which drains into the Zymoetz River. Moore Creek and some of its tributaries run all year and can provide sufficient water for exploration and mining purposes. The outcrop distribution is highly variable on the claims. Outcrops are abundant along the top of Ashman Ridge, but they are generally rare on the lower slopes in the claims area.

PREVIOUS WORK Local small fracture fillings of copper minerals were found in felsic volcanic rocks within the area of the claims during logging road construction in the 990s. The showings were staked by Harold Thomas Hendrickson, under whose direction a flagged grid was prepared in the area of the showings. A VLF-EM survey was conducted over the grid and some short diamond drill holes were put down. The claims lapsed and the area was staked by Regis Plante in 200 (Willy -4) and 2002 (Regis -5). During the 2002 field season, Mr Plante drilled two short diamond drill holes in felsic volcanic rocks to test a VLF-EM anomaly. A conductive fault was intersected in one of the holes, but the test would have benefited from a longer hole. I confirmed part of the VLF- EM anomaly using a Phoenix VLF-2 electromagnetic receiver and I collected eleven reconnaissance silt and soil samples in the same general area, some of which carried anomalous amounts of lead (s 24 ppm) and zinc (5 552 pprn), or silver (I 3.6 ppm), copper ( 97 ppm) and molybdenum (r6 ppm). The geochemical analyses (aqua regia-icpaes) were performed by ALS Chemex of Vancouver, B.C.
-3- GEOLOGY The general area of the claims lies in the Stikine terrane of the Intermontane Belt, on the northern edge of the Skeena Arch and near the southern edge of the Bowser Basin. Much of the area is underlain by island arc volcanic and sedimentary rocks of the Hazelton Group (Jurassic), with basin-filling sandy and shaly rocks of the Bowser Lake (Jurassic) and Skeena (Cretaceous) groups to the north. In places, these rocks are cut by granitic intrusions of Late Cretaceous and Eocene age, some of which host mineral deposits with economic potential, and the area lies within a north-northwesterly trending belt of porphyry copper, molybdenum and other deposits that are associated with intrusions of Late Cretaceous or Tertiary age (Carter, 982). The geology has been mapped by Tipper (976) and the regional geological setting has been discussed by Tipper and Richards ( 976). All the confirmed outcrops discovered during prospecting on the claims to date are volcanic rocks assigned to the Lower Jurassic Telkwa Formation of the Hazelton Group. Most of these rocks are hematitic, subaerial, dacites or rhyolites. ADJACENT PROPERTIES The Paddy claims adjoin the Regis claims on the west. A widely-spaced soil geochemical program was conducted there in 997 and no significant anomalies were found (Chow, 998). The maximum results (aqua regia digestion/ ICP; Au by MIBK extraction and GFAA analysis) obtained in that survey for some selected elements follow: Au 30 ppb, Ag.8 ppm, Pb 47 ppm, Zn 248 ppm, Cu 56 ppm and Mo ppm. Other nearby prospects are the Zymo porphyry copper prospect, about 3 km west of the claims (Nelson, 2000); the Lefty showing, which is an apparently small copper occurrence in volcanic rocks a few hundred metres north of the claims (Minfile Number 093L 078); and the Louise Lake copper-gold porphyry system where there is an estimated resource of 50 million tonnes of 0.3% copper and 0.3 g/t gold and where work continued in 2004 (News release, Firestone Ventures Inc., 5 September 2004). The Louise Lake prospect is about km northeast of the Regis claims. PROSPECTING RESULTS Many outcrops of felsic volcanic rocks, including reddish hematitic tuffs, were observed during prospecting along the upper parts of the south slope of the southern end of Ashman Ridge. All these rocks are assigned to the Hazelton Group, and most are lacking in sulphide minerals of economic interest. However, a copper occurrence was discovered by Regis Plante at about 675m elevation in this area (figure 3) and the showing has been examined by me. The following NAD 83 UTM coordinates of the discovery were obtained using a Magellan SporTrak Map GPS receiver: 09 573567E and 6076494N. Chalcopyrite and malachite occur here in a brecciated fault zone in a greyish red felsic volcanic host, poorly exposed in a small creek. The main malachite zone is approximately 5 cm in width. Also present are iron oxides, dendritic manganese oxides, calcite and an iron carbonate mineral in fracture fillings and disseminations. The mineralized fault may be controlled by a bedding plane and may strike about 290" and dip approximately 45' south. A few outcrops were found in the Grid area in the central claims, including several outcrops of a quartz-feldspar-porphyry tuff. These outcrops are shown on the geochemical survey Grid map (figure 4). Pyrite is rare in these rocks, but disseminated specular hematite was noted in several outcrops.

-4- Small amounts of malachite, azurite, tetrahedrite, and relatively abundant iron and manganese oxides occur in a narrow fault zone in greyish red purple felsic tuff, accompanied by quartz and carbonate veinlets, in a road cut west of the upper Moore Creek bridge on the 7000 road. The fault zone trends 030" and dips at 85" to the southeast. The following NAD 83 UTM coordinates for this showing were obtained with a Garmin GPS 2 receiver: 09 573230E and 6074874N, elevation040 m. This showing was drilled by Harold Hendrickson in the 990s with inconclusive results. GEOCHEMISTRY The soil sampling grids are shown on figures 3,4,5,6 and 7. Grid includes an enlargement of the Hendrickson grid which was established to control a VLF-EM survey and upon which a VLF-EM anomaly was discovered. Grid 2 was designed by Regis Plante to test a geochemical anomaly. Overburden is mostly till that varies in thickness from a few centimetres to many metres. One hundred and seventy-seven soil or silt samples were collected, of which 0 silt samples yielded insufficient sample material for analysis. Soil samples were recovered from Grid at intervals of 50 m or 00 m on flagged lines approximately 00 m or 200 m apart, depending upon grid sector. Soil samples were collected on Grid 2 at intervals of 50 m on flagged lines 00 m apart. Where possible, the samples were taken from the B soil horizon. The samples were retrieved with a shovel, placed in standard haft soil bags, air dried and were shipped by air to the ALS Chemex laboratory in North Vancouver, B.C. There the samples were analyzed for 34 elements using an aqua regia digestion and ICP-AES (code ME-ICP4; inductively coupled plasma-atomic emission spectroscopy) and tested for gold by fire assay-atomic absorbtion spectroscopy (code Au-AA23) using a 30 g nominal sample weight. The analytical results and field notes are in the Appendix. The geochemical thresholds were chosen in the 95'" percentile for each element and some comments on selected elements follow. GUM. The threshold for gold has been chosen at 0.02 ppm, above which there are eight anomalous samples (50.645 pprn), the best of which were collected on Grid (Figure 4) Sher The silver threshold selected is ppm. There are anomalous results on lower Grid (52.6 ppm)and on the west side of Grid 2 (g.5 ppm). Cupper. With the anomaly threshold set at 50 ppm, there are only six modestly anomalous Cu samples (279 ppm). Molybdenum. Five samples exceed the threshold of 4 ppm. The strongest results came from scattered localities on Grid 2 (5 5 pprn). Lead. The threshold for lead is 27. Eight samples are anomalous and the strongest are spatially related to the Moore Creek drainage on Grid 2 (34 ppm). Zinc. There are eight anomalous zinc samples, using a threshold of 70 ppm. Most, and the strongest, are on the western half of Grid 2 (5246 ppm).
-5- CONCLUSIONS AND RECOMMENDATIONS, The Regis mineral claims cover an area generally underlain by felsic volcanic rocks of the Hazelton Group, including a quartz-rich tuff, in a belt with recognized economic potential. 2. Prospecting during 2004 resulted in the discovery of a copper occurrence in felsic, hematitic, volcanic rocks on the southern slope of Ashman Ridge. The occurrence is not of economic interest. 3. The geochemical surveys yielded some scattered anomalous results, the most interesting of which, especially for gold, are from silt samples on Grid. A silt sampling and detailed prospecting program in the Grid area should be completed before another soil sampling program is contemplated. Care must be taken to collect larger silt samples than in the first survey in order to ensure sufficient material for analysis, and the creeks and sample locations should be shown on a topographic map. 4. Silt samples should be collected elsewhere in the Moore Creek drainage system in the claims area, such that all silt-bearing tributaries are sampled. REFERENCES Carter, N.C., 982.
