The Claw occurrence is situated on a north-trending ridge approximately 3.5 kilometres northwest of Claw Mountain about 260 kilometres northwest of the community of Germansen Landing.

The area 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.

Devonian-Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Stuhini Group andesite flows and pyroclastic rocks. Stuhini 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 Claw prospect is underlain by Stuhini Group augite porphyry andesites, amygdaloidal andesite and basalt flows, minor agglomerates and tuffs. This sequence is locally intruded by andesite dikes. All of the units have undergone weak propylitic alteration; epidote and chlorite are ubiquitous. Calcite, chlorite, zeolites and native copper often fill the amygdules. Hematite and magnetite are found disseminated throughout the volcanic units. Sheared and fractured zones are abundant and are associated with limonite and minor albite alteration of the wallrock.

Two modes of mineralization occur, both are widespread. Chalcopyrite, bornite, chalcocite, malachite and minor chrysocolla are hosted within quartz-carbonate veins and along fracture surfaces associated with the shear zones. A chip sample of the 100 by 80 metre main zone, with a vein system striking 125 degrees and dipping 80 degrees east, assayed 2.3 per cent copper and 28 grams per tonne silver (sample 84-CK-49, Assessment Report 12871). The second type of mineralization occurs as disseminations and amygdule fillings of native copper, chrysocolla and malachite with minor chalcopyrite and bornite. This type of mineralization is locally abundant but sporadically distributed. Chip samples of a high-grade zone of this material assayed 8.2 per cent copper and 214.89 grams per tonne silver (sample 84-CK-35, Assessment Report 12871).

Between 1974 and 1975, Union Miniere Explorations and Mining Corporation Limited conducted geological mapping, soil geochemistry and magnetometer geophysical surveys and drilled seven diamond-drill holes totaling 1130 metres.

In 1982, Western Horizons Resources Ltd. staked the property and in 1984 completed geological mapping and rock sampling. In 1986, Western Horizons Resources Ltd. allowed the claims to lapse and S.C. Gower and E.M. Thompson staked the property and completed geological reconnaissance, soil sampling and rock sampling. Highlights include rock sample SB-86-TR-2104, which assayed 106.3 grams per tonne silver and 2.874 per cent copper (Assessment Report 16140).

In 1990, the Silver Glance and Silver Bluff claims were transferred to Electrum Resource Corp. The Silver Bluff claims covered the Claw occurrence while the Silver Glance covered the Copper King (094E 233) and the Claw. In 1990, Electrum Resource Corp. completed silt and rock sampling programs. Highlights include rock sample SB-90-040R which assayed 178 grams per tonne silver and 3.86 per cent copper (Assessment Report 20729).

In 2001, Electrum Resource Corp. staked the Tan claims and did a 1-day reconnaissance of the property. The claims covered the Chuck (094E 019), Claw, Goat (094E 062), and Copper King (094E 233) mineral occurrences. Electrum collected 9 rock chip samples, 5 soil samples and 1 stream sample. Several samples were taken in the Claw area in 2001. In 2007, Electrum collected 122 soil, 11 silt and 9 rock samples from the Tan 1-4 claims. A soil line was completed in a northeast direction through the Claw showing area.

In 2017 and 2018, Evergold Corp. completed programs of prospecting, geochemical (soil and rock) sampling and an airborne geophysical survey on the area as the Golden Lion property.
