Capsule Geology

The Ural (L.2944) occurrence is located near the south side of Cambridge Creek, approximately 2.1 kilometres southeast of the creek’s junction with Trail Creek.

Regionally, the area is underlain by augite-phyric lapilli tuff, pyroclastics and flows of the Lower Jurassic Elise Formation (Rossland Group), which have been intruded by quartz monzonitic rocks of the Early Jurassic Rossland Plutonic Suite, granodioritic rocks of the Middle Jurassic Nelson Batholith, granitic rocks of the Eocene Sheppard Intrusions and syenitic to monzonitic rocks of the Eocene Coryell Plutonic Suite.

The area is underlain primarily by monzonite of the Early Jurassic Rossland Plutonic Suite near its contact with basaltic volcanic rocks and sediments of the Lower Jurassic Elise Formation. The monzonites have been chlorite- and epidote-altered. Pulaskite dikes are reported to occur in the area of the occurrence. The rocks are traversed by numerous faults. The major regional fault, Violin Lake fault, traverses the rocks paralleling Cambridge Creek.

Locally, a small, 5- to 10-centimetre wide, quartz-sulphide vein or fracture filling hosted by an altered monzonite is exposed by former workings over a strike length of 10 metres. The vein infills a shear and is comprised of arsenopyrite, pyrite and minor pyrrhotite in a gangue of altered hostrock. Minor lead and zinc mineralization with some silver and gold was reported. The mineralization is compared to the South belt type of mineralization in the Rossland Camp, which contains pyrite, pyrrhotite, arsenopyrite, sphalerite and galena. The mineralized vein is reportedly terminated by a north-south-trending shear to the west.

In 1984, a sample from the vein assayed 24.0 grams per tonne gold (Assessment Report 12644).

In 1986, a sample (6238) from a pit or short shaft assayed 3.4 grams per tonne silver and 6.7 grams per tonne gold over 0.33 metres of fracture and wallrock, whereas a high-grade dump sample (6239) yielded 3.4 grams per tonne silver and 25.3 grams per tonne gold (Assessment Report 18310). A second shallow pit is located 6 to 8 metres east of the first and yielded 5.5 grams per tonne silver and 7.4 grams per tonne gold over 0.5 metre (Assessment Report 18310).

In 1988, samples yielded up to 12.6 grams per tonne gold (Assessment Report 18310).

In 2006, three samples (RP-64 to -66) from former workings yielded from 0.750 to 4.813 grams per tonne gold (Assessment Report 28996).

The area has been explored since the late 1800s and/or early 1900s. In 1935 and 1936, 8 tonnes of ore were shipped yielding 218 grams gold and 311 grams silver. The nature of the deposit and its ore was not reported. Former workings include several pits and trenches up to approximately 5 metres in depth.

In 1948, Valley Mining Co. completed a program of geological mapping and a 10.0 line-kilometre self-potential survey on the area. In 1984 a program of prospecting, rock sampling and a ground magnetic survey was completed on the area as the Nobus claim. In 1986, a program of prospecting, geological mapping and rock sampling was completed on the area as the Beaver claim.

In 1987 and 1988, Tobex Resources completed a program of geochemical sampling and a 113.0 line-kilometre airborne geophysical survey on the surrounding area as the Gold Dust and Decoy claims. Also, 1988, Kerr Addison Mines Ltd., on behalf of Inland Au-Ag Resources Ltd., completed a program of geochemical sampling and trenching on the Cam 2 and Nobus claims. In 1989, Inland Au-Ag Resources Ltd. completed a program of geological mapping and a 4.4 line-kilometre ground magnetic survey on the area as the Beaver claim.

In 2006, Klondike Gold Corp. completed a program of soil sampling, geological mapping, 20.3 line-kilometres of ground geophysical surveys and a 317.8 line-kilometre airborne geophysical survey on the area as the Red Point property.
