Also known as the Kennedy Eclipse.

From the California Journal of Mines and Geology, Vol. 47, No. 1, Jan. 1951:

4 patented claims, the Eclipse Nos. 1 and 2 and the Comet Nos. 1 and 2, are owned by A.E. Nicholls, 1400 E. Olympic Blvd., Los Angeles and leased to the Kennedy Minerals Company, 2550 E. Olympic Blvd., Los Angeles.

The talc deposits at the Eclipse mine are typical of many in the region in that they have formed adjacent to the upper margin of a diabase sill and represent an alteration of the lowermost carbonate sediments of the Crystal Spring formation.

The talc bed mined on the two Eclipse claims, is 12 to 16 feet thick, strikes N. 45°-50° E., and dips 30° SE. In the older workings on the Eclipse No. 1 claim the talc was cut by a fault striking N. 79° E. and dipping 80° N.

The Eclipse No. 1 claim was worked by three adit levels at intervals of 30 and 50 feet. The lowest level was driven to intersect the faulted talc vein and has about 700 feet of drifts and crosscuts. The two upper levels were stoped extensively and are now caved. The Kennedy Minerals Company obtained a lease in 1940 and mined about 12,000 tons of talc from these workings. It is estimated that the total production was about 50,000 tons of talc.

Recent work by Kennedy Minerals has been on the Eclipse No. 2 claim. A cross cut adit has been driven 175 feet and a 70-foot raise intersects the talc which has flattened in dip. A crosscut was driven to the surface again from the top of the raise and drifting has been started from the raise. About 500 tons of talc has been produced from these workings.

The property has been worked intermittently on a contract basis.
