The Emma Mine is 10.2 kilometres northeast of Greenwood, at the elevation 1066 metres on the divide between Eholt and Fisherman creeks. The property adjoins the Oro Denoro Mine (082ESE063) to the south. Access to these properties is about 0.6 kilometre southwest from Highway 3 by level gravel road along an old railway bed.

At Emma, mining began from a skarn zone exposed during railroad construction in 1894. By 1905, production was derived mainly from underground development that consisted of a two- compartment shaft, 80 metres deep, with levels at 45 and 75 metres. A fire disrupted operations in 1912, however, the workings were restored in 1916 and production continued until 1921. Underground development in this period included 50 metres of shaft sinking, 285 metres of raising, and 770 metres of drift and crosscut tunnelling.

Production in the period 1901 to 1927, totalled 241,538 tonnes of ore, containing, 211.8 kilograms of gold, 2434 kilograms of silver and 2350 tonnes of copper.

The orebody at the Emma Mine is vertical and strikes northerly, roughly parallel to the bedding in the Brooklyn (Triassic) limestone, near the eastern contact of the Wallace Creek (Jurassic- Cretaceous) granodiorite body. Mineralization, consisting mostly of pyrite, chalcopyrite, and magnetite impregnations in garnetite, is mostly confined to a narrow zone about 8 metres wide and 100 metres long.

In 1987, Skylark Resoures Ltd. drilled 873 metres in 6 holes on the Emma, Mountain Rose and Jumbo claims. Several mineralized intervals were intersected in the holes, including a 1.5-metre width of 0.018 per cent germanium. Other holes encountered zinc and molybdenum mineralization. (Assessment Report 17308).

A grab sample assayed 0.16 per cent copper, 1.2 grams per tonne silver and 0.14 per cent cobalt (EMPR Bulletin 101, Appendix 4B).

Echo Bay Mines Ltd. drilled 5 holes totalling 250 metres in 1997.
