The Oro Fino workings occupy a 25-hectare claim located at the headwaters of Nilsik (Crazy Jane) Creek, south of Sunset and Outlook mountains. The property is located in Kokanne Glacier Provincial Park. Production in 1940 totalled 4 tonnes and yielded 62 grams gold, 964 grams silver, 48 kilograms lead and 112 kilograms zinc.

Development work includes two adits at the 2086-metre and 2118-metre elevations and surface trenching at 2196 metres elevation outlining a strike length of approximately 100 metres. The quartz vein occupies a tight fracture in potassium feldspar-porphyritic granite which strikes 030 degrees and dips 65 degrees southeast. Vein mineralogy comprises pyrite, sphalerite and galena: stronger mineralization is associated with smoky quartz. Wallrock is oxidized and altered to sericite and argillite assemblages up to 10 centimetres on either side of the vein.

A grab sample taken in 1987 of mineralized vein material stockpiled at the upper portal returned 24 grams per tonne gold, 390 grams per tonne silver, 2.8 per cent lead and 3.8 per cent zinc. Altered wallrock sampled from directly inside the lower portal returned 0.11 gram per tonne gold, 8 grams per tonne silver, trace lead and 0.01 per cent zinc (Open File 1988-11 and Paper 1989-5, page 24).
