Agency: NF Region District: R1 Ranger District: JEFFERSON Forest Service Tract: Watershed Code: 10020006 Forest or Resource Area: DEERLODGE Owner: P Impact: V Report: Crystal The geology of the Crystal is well described in other references (Roby and others, 1960; Ruppel, 1963; unpublished information, MBMG files), and its environmental effects have been the subject of several studies (...........). Therefore it was not studied as a part of this project, but a summary of the property is provided because it is one of the major contributors to degradation of the Cataract Creek watershed. The mine produced from underground workings and open pits from 1908 until at least the 1960s. Total production has been 22,586 tons with 3579 oz Au, 343,591 oz Ag, 536,915 lbs Cu, 2,060,623 lbs Pb, and 939,190 lbs Zn recovered (Roby and others, 1960). Two adits with 6000 feet of workings over a vertical range of 200-300 feet mined a N70-80W 70NE vein in sericitized aplite. The ore shoots were discontinuous lenses 2-30 feet wide of quartz, pyrite, arsenopyrite, galena, chalcopyrite, tetrahedrite, covellite, and chalcocite. Though no vertical zoning is evident, some zoning across the width of the shear zone was noted (Ruppel, 1963). Ore in the footwall shoots contained over 1 oz/ton Au, while in the central and hanging wall shoots gold content was negligible and silver values were higher. Several studies at Montana Tech have helped characterize the effect of the large volume of acid water emerging from the lower adit....................... |
