The ore was initially reached through two adits with crosscut drifting. Crews later sank a 300-foot shaft and developed three levels. Processing of the ore was quite different, however. The American mine ran ore through a concentrator set near the portal of the mine. The ore passed first through a 4-inch grizzly to a jaw crusher.

Five models are available. Application shows that the recovery can be as high as 90%, especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of 0. 074mm, the recovery for the natural gold is expected up to 98%, For that natural gold of 0.004mm in particle size, the recovery is 97%.

Gold is gold, so there isn't necessarily a better type of gold. However, mining for lode gold has many more challenges that mining for placer gold. Placer gold mining is much easier. The gold is already separated from the rock, and gravity has concentrated the gold into creeks and rivers where it is more easily accessible.

The mine changed owners several times, and production resumed in 1907 and again in the 1920s, but without success. The Boston-American Mining Company was the last attempt mining operations here. The company built a new concentrator at Monte Cristo and a tramway from the mine to the concentrator. No ore was ever shipped down that tram.

From 1987-1990, under previous management, Citigold Alaska, Inc. attempted heap leaching 295,000 metric tons of the Ryan Lode ore with moderate success, at an estimated gold recovery of 60-65%. Previous work (Walsh, 1989, 1991, 1992) has shown that significant, free milling gold values exist in the Ryan Lode ore.
