Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite
Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!

A former tiny Bi-Zn-Cu mine located in sec. 19, T19S, R41E (MDM), 1.5 km (0.93 mi) ENE of Darwin, near the Custer Mine. Worked in the 1950s when the larger mines in the area were working. Once the small copper-zinc orebody was mined out, the mine was abandoned. Corrected description and position N36.27318 W117.57504 by Richard Muster, courtesy Gail Dunning, Walt Margerum and Robert Hously.

Note: This mine is not listed in the USGS MRDS database.

The orebody was unusual in the fact that, in an area of Pb-Ag and W mines, the ores were predominately Cu & Zn. The rocks in this near surface mine are weathered interbedded calc-hornfels and altered to tactite.

It is rather different from the nearby mines, and the minerals it contained were also distinctly different. The brochantite and serpierite were well crystallized, and the serpierite find represented the first California locality for this mineral.

The mine is located between the St. Charles Mine and the Custer Mine, but is closer to the Custer than the St. Charles. To get there you need to hike approximately 2,000 feet (ca. 610 m) down (eastwards) Custer Canyon. After you pass the St. Charles loading chute, you will see the Custer mine to your left. As you start up the side road to the Custer mine, you will see a small road leading to your left. This is the track to the Lucky Lucy mine. There is some lumber on the side of the hill below the mine. The pit is not visible until you are almost on top of it.

Workings include surface openings composed only of a single pit about 4 meters deep extending into the side of the hill.

Some visitors reporting minerals from the Custer mine might have actually been at the Lucky Lucy mine.
