Capsule Geology

The Har prospect consists of several samples yielding anomalous gold, silver, lead and zinc from quartz-carbonate veins, and sulphide veins within rebrecciated quartz (Assessment Reports 15474, 18335). The prospect is located 6.25 kilometres southwest of Breccia Peak, west of Moosehorn Creek and south of Hiamadam Creek in the north-central part of the Toodoggone gold camp. Smithers is located 310 kilometres to the south.

The Har prospect is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins. Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. Takla volcanics have been intruded by the granodiorite to quartz monzonite Black Lake Suite of Early Jurassic age and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation, Hazelton Group.

The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The Har prospect is underlain by volcanics of the McClair Creek Member of the Toodoggone Formation. At this location they are composed of interbedded porphyritic flows, flow breccias, crystal tuffs and crystal lithic breccias. Minor volcaniclastic sediments are also present. Intensely fractured, porphyritic monzodiorite dikes cut the above units.

These lithologies show generally weak chlorite and carbonate alteration. Feldspar matrix and phenocrysts are weakly affected by sericitic and argillic alteration. Takla volcanics outcrop immediately to the east.

The Har prospect originally consisted of a quartz-carbonate vein mineralized with sporadic galena, sphalerite, chalcopyrite and pyrite. Subsequent property work, in 1986, has discovered a quartz vein with galena cutting porphyritic andesite, approximately 350 metres east of the original vein. Assay results from grab sample GD-86-3007 of this material, were 0.375 gram per tonne gold and 3.5 grams per tonne silver (Assessment Report 15474).

In 1988, a more comprehensive property exploration program discovered three other significant mineralized zones within 200 metres of the original vein. Sample GD-88-018 and 019 were taken across high-grade massive sulphide seams 10 to 15 centimetres thick. The seams strike 100 degrees and dip 25 degrees to the southwest. The former sample assayed 0.171 gram per tonne gold, 21.94 grams per tonne silver, 4.56 per cent lead and 22.23 per cent zinc. The latter sample analysed insignificant gold but 12.0 grams per tonne silver, 5.8 per cent lead and 1.16 per cent zinc. Sample GD-88-012 was taken from limestone mineralized with ribbons of sphalerite and galena over approximately 1 metre. The sample yielded insignificant gold but 7.89 grams per tonne silver, 0.66 per cent lead and 2.15 per cent zinc. A re-brecciated quartz-sulphide vein with minor galena, sphalerite and pyrite was sampled. Sample GD-88-008 from this vein assayed insignificant gold, 20.57 grams per tonne silver, 0.32 per cent lead and 0.59 per cent zinc (Assessment Report 18335).

In 2005, float in the talus slide below the Har "vein" was reported to consist of very large (3 - 5 ton) mineralized boulders, presumed to be sourced from the 1 to 2 metre wide vein in the cliff upslope to the south. The boulders are quartz-carbonate (calcite) and barite with occasional massive sphalerite and galena. Copper mineralization as stains and chalcopyrite is subordinate. This area is known as an epithermal quartz-carbonate (calcite) and barite vein system with occasional massive sphalerite and galena.

Work History

The Har 1-6 claims were owned by Kennco Explorations, (Western) Limited. During 1973 Conwest Exploration Company Limited carried out a geochemical silt, soil, and talus fines survey (122 samples) covering all claims.

In 1982, the Gord Davies claim-was staked by Elaine M. Thompson and was subsequently transferred to Western Horizons Resources Ltd. In 1983, a geological

Exploration for 1983 on the Gord Davies Property was filed by K. E. Northcote. A Petrographic Report on the Property was filed by K. E. Northcote in 1985 to cover one year's assessment.

In 1988, an exploration program was carried out by Gower, Thompson & Associates Ltd. in 1988 consisting of 25 rock, 2 silt and 15 soil geochemistry and geological mapping.

In 2004 and 2005 the Breccia-Claw property of Stealth Minerals Ltd contained previously discovered occurrence such as Golden Lion (094E 077), Yellow Dog (094E 041), Gord Davies East (094E 199) and Gord Davies West (094E 198) showings and Har (094E 053) prospect.

The 2004 field program completed on the Breccia-Claw claims by Stealth Minerals consisted of rock and soil sampling. Alteration identification via PIMA spectrographic analysis was done on 95 selected rock samples. A total of 349 surface rock samples were taken as float or outcrop samples.

In 2005, Stealth Minerals collected a total of 37 surface rock samples from float or outcrop samples.
