This property lies on the summit between Sheep & Lost Creeks, about 11.2 kilometres southeast of Salmo. Although the Emerald has in recent years been a tungsten producer (082FSW010), its early history as a lead-zinc producer is mentioned here because the Jersey (082FSW009) workings were later extended into Emerald ground and production figures for the two have not been recorded separately.

Production of lead-zinc ore from the Emerald was begun in 1906 by the owner, J. Waldbesen. In 1917 Iron Mountain Ltd. was formed to operate the mine and a 23 tonne mill was put into operation. The Emerald was a small but steady producer of lead- zinc ore from 1906 to 1925.

A small amount of shallow development work was done on the Jersey claim (082FSW009) from 1916 to 1919 and some ore was shipped, however the main ore deposit was not discovered at this time.

Canadian Exploration Ltd., while operating the Emerald tungsten mine, carried out an extensive diamond drilling program on the Jersey during 1948 and a large tonnage of lead-zinc ore was outlined. During 1948-49 the Emerald tungsten operation was closed down and the mill, beside the Nelson-Nelway Highway, was converted to a lead-zinc operation and production from the Jersey began in March 1949. The mine has operated continuously since that time, development work being done on all seven ore zones. Track mining has been used in A, C, and D zones and trackless mining in A, D, E, F, and G zones. The A zone has been developed from the south end of the Jersey zone to a point north of the Emerald, a distance of 1524 metres.

Ore reserves as of April 1, 1965 are reported at 671,075 tonnes grading 1.2 per cent lead and 4.1 per cent zinc.

The Emerald lead-zinc ores are similar in nature to the HB deposits (082FSW004) except that lead predominates. Galena runs over 40 per cent with about 6 per cent zinc and 50 grams of silver. There is evidence to suggest the Emerald ores are controlled more by flat shears than vertical ones.

The galena-sphalerite-pyrite-pyrrhotite ores occur in several parallel zones and are characterized by their banded nature. They are hosted by dolomitized Reeves Member limestones of the Lower Cambrian Laib Formation.

Skarn with minor molybdenum was noted during underground development in 1915. Records indicate that over 50,000 tonnes of ore were shipped between 1906 and 1925 but details are not available. However, the production data, as recorded for the adjacent Jersey mine (082FSW009), indicates a distinct period of production during the 1906 to 1925 period in which 25,850 tonnes of ore were mined and 705,292 grams of silver, 6,788,936 kilograms of lead and 19,771 kilograms of zinc were recovered.

In 2005, Sultan Minerals Inc. completed 20 underground drill holes, totalling 6859.6 metres, and two surface drill holes on the Dodger Tungsten mine workings, particularly the Dodger 4200 zone. In 2006, eight diamond drill holes, totalling 1016 metres, were completed on the East Emerald Tungsten zone, also referred to as the Dodger “D” zone. In 2007, a further 19 underground drill holes, totalling 3886 metres, were completed on the East Dodger molybdenite zone and 61 surface drill holes, totalling 9147 metres, were completed on the property. During 2008 through 2010, programs of soil sampling and airborne geophysical surveys were completed on the property. In 2014, Margaux Resources Ltd. completed 35 diamond drill holes, totalling 6,318.6 metres, on the East Emerald zone.
