Per Geology and Ore Deposits of the Front Range Colorado By T. S. LOVERING and E. N. GODDARD (GEOLOGICAL SURVEY PROFESSIONAL PAPER 223)
"Development.-Shaft and levels; 5th level joins 3rd level of Conger.
Production.-Prior to 1914: 250 tons of concentrates worth $90,000. Subsequent to 1914: "Considerable tonnage."
Veins.-Bettig: Strike, N. 30° E.; dip, 45° SE.; width, 1 inch to 3 feet. Joins Conger vein at 5th level and is mined at depth through Conger mine. Sperry: Strike, southerly; branch of Bettig.
Wall rock.-Pegmatite, granite, and schist, cut by dikes of felsite and hornblende monzonite porphyry.
Ore and sulfide minerals.-Chiefly ferberite, a little marcasite and sphalerite.
Gangue minerals.-Wall rock breccia and chalcedonic quartz.
Changes with depth.-Sperry vein barren below 5th level of Bettig.
Ore shoots.-Pitched northeast at a low angle. Localized by intersection of hornblende monzonite porphyry dike and vein.
Tenor.-Sperry vein contained good ore near surface."
