The Elkhorn (Lot 818) mine is centred on Highway 3 near the north boundary of Greenwood municipality. See Providence (082ESE001) for a detailed regional geology.

Production from this property has been episodic in the period 1905 to 1947 and has never exceeded 30 tonnes per year. Total recorded mine output amounts to 179 tonnes of ore which yielded 5.2 kilograms of gold, 456.5 kilograms of silver, 8.2 tonnes of lead, and 1.7 tonnes of zinc.

The mine workings consist of an inclined shaft 80 metres deep servicing a level at the bottom, and an upper level at about 20 metres depth. The shaft is also connected to an intermediate adit level at 34 metres depth. The underground workings follow a narrow quartz vein, dipping 45 to 65 degrees southeast, hosted by silicified Knob Hill schists (Paleozoic) outcropping near the north contact of the Greenwood granodiorite stock (Jurassic-Cretaceous).

The ore minerals consist of pyrite, galena, sphalerite and minor amounts of tetrahedrite and proustite. Some native silver has been reported in the stopes above the adit level.

The vein is cut by several faults that strike north 30 to 50 degrees east and dip at low angles to the northwest. The hanging wall in each case moved down with reference to the footwall. Offsets along these faults range from a few metres to 9 metres. On the 34-metre adit level, the vein is cut by two post-mineral feldspar porphyry dikes, and has not been located beyond the dike that is exposed 41 metres northeast of the inclined shaft. The other dike, which is exposed in the level at the inclined shaft, has not offset the vein.

No ore reserves are available for this property.
