Wonder Mine (Wonder prospect; Wallace Wonder Mine; Wonder No 1), Darwin, Darwin District, Inyo Co., California, USA

Latitude: 36°17'2"N
Longitude: 117°34'34"W
A former small Pb-Ag-Cu-Au mine, 7290 feet N38°E from Darwin in NW quarter of sec.18 T19S R41E at an elevation of 4540 feet.

It consisted of 4 claims, N and S of the Lane Canyon Road (now N. Main Street), originally owned by Richard Wallace, later the Anaconda Co owned the mine.
The older workings consisted of an adit S of the canyon road. The newer workings, N of the Canyon Road, consisted of 2 inclined shafts, an adit and several surface pits.
Little is known of the older parts. The mine N of the canyon road was mainly worked in 1947. Ore had recoverable 2.5% Pb, 3.8 oz Ag per ton and some copper.

The ore occurs as irregular lenses of galena and lead-carbonate along a fissure in the limestone that strikes northwest and dips 45° W.
The vein-filling is a coarse calcite with some crystalline fluorite. Local structures include a fault and fold.

Production data are found in: Goodwin, J.G. (1957): 523.

It is argued by some that the Wonder mine and the Bruce mine are one entity but Hall, Wayne Everett & E.M. Mackevett list it as separate mines, furthermore the Wonder mine is a Silver - Lead mine, whereas the Bruce mine is a Tungsten mine.

Updated description and position of the mine N36.28397 W117.57632 and N36.28501 W117.57648 by Richard Muster, based on observations in 2007.

The older parts are at N36.28020 W117.58036, N36.27976 W117.57995, N36.28003 W117.57941 and N36.28054 W117.57949.
