The Elkhorn Fr. (Lot 297S) is located north of Greenwood, between the Elkhorn (082ESE002) to the west and Providence (082ESE001) to the east.
Production from 1925 to 1927 amounted to 44 tonnes of ore, yielding 249 grams of gold, 241.8 kilograms of silver, 2.3 tonnes of lead, and 5.3 tonnes of zinc.
A 5 to 40-centimetre wide quartz vein is hosted by silicified Knob Hill schists (Paleozoic) outcroppping near the north contact of the Greenwood granodiorite stock (Cretaceous). The ore minerals consist of pyrite, galena, sphalerite, argentite, native silver and native gold. The vein is likely an extension of the Providence vein.
