The D & D Smelter expanded into new buildings in 1890 and operated sporadically. The pyritic smelting process was soon overshadowed by a new, cheaper ore treatment method using cyanide, and two competing processing plants were built in Deadwood in 1894. The D & D Smelter started adding copper in 1895 for a more efficient extraction process.

The gold was won from alluvium in the "valley" and the gullies running into it. At the head of the "valley" a small hill of metasediments carried leaders of quartz showing free gold. A shaft was sunk on these leaders but was abandoned after 9 tons of ore, yielding 12 oz 6 dwt of gold, was recovered.
