Cedar Tree claim (Cedar Tree deposit; Porphyry Reserve Copper Co. claims; Bessie claim group; Louis D'Or group), Claypool, Miami-Inspiration District, Globe-Miami District, Gila Co., Arizona, USA
Latitude: 33°26'14"N
Longitude: 110°52'50"W
A former underground Pb-Cu-Ag-Au-Zn mine located on 1 claim in the center S½S½ sec. 12, T1N, R14E, 4,000 feet SW of the Copper Cities Mine and about 2½ miles NW of Claypool, on federal land. Operated about 1913 by the Louis d'Or Gold Mining Co. Operated by Fallgren and Libbym (1933). Closed 1933.
Mineralization is a replacement deposit with an irregular ore body.
This claim is located near the south contact of the Lost Gulch Quartz Monzonite mass. The deposit was a small oreshoot along a minor fissure between two tongues of quartz monzonite projecting southward from the main mass in the adjacent Pinal Schist. The fissure strikes N70E and dips 80S. Its trace is apparent only where it crosses the schist and a narrow diabase dike intruded along the east contact. The schist in this area is intricately intruded by fine-grained rocks of the Precambrian diorite complex.
The oreshoot was approximately 3 to 4 feet wide based on the width of the stopes. Vein matter consisted mainly of quartz containing irregular stringers and small masses of galena and sphalerite and very minor amounts of chalcopyrite and euhedral pyrite. The quartz is generally fine-grained and stony but contains numerous drusy cavities and partly replaced fragments of country rock. The vein is clearly a replacement of the schist and dioritic rocks along a narrow breccia zone.
Workings include an adit driven along the fissure from a gulch at the west end, and total 30.48 meters in length and 22.86 meters in depth. No records of the production of metals or grade of ore are available. The total ore mined was less than 2500 tons.
