A former surface Li-Be-Feldspar-Mica mine located near the SE ¼ sec. 9, T.7N., R.3W. Owned by Earl F. Anderson of Mesa, AZ.
Mineralization is a very irregular, poorly zoned dike that trends North to NNE & dips steeply westward. It is enclosed by hard, fine-grained, greenish-gray feldspathic hornblende gneiss that is thinly & regularly layered. Its well-developed foliation strikes N.85ºW. & dips 45º to 60ºN. It is 170 feet long by 50 feet wide.
The pegmatite body is a connected pair of elongate bulges whose major axes plunge very gently in a northerly direction. It was introduced along fractures, bedding and foliation planes, and along country rock contacts. Emplacement was probably by mechanical injection of liquids, accompanied by local replacement of susceptible types of country rock.
The second dike is 8 to 15 feet thick separated from the main dike by 20 to 45 feet of country rock gneiss. As traced NE-ward, it joins the upper bulge of the main dike high on the canyon wall.
The principal opening is a small stripping quarry (1951-52). Output was a carload of spodumene (late 1951).
