Agency: NF Region District: R1 Ranger District: HELENA Forest Service Tract: Watershed Code: 17010201 Forest or Resource Area: HELENA Owner: N Impact: Report: Cyclone/ Whirlwind PO005170 The Cyclone (later called the Whirlwind) is located in the NEĽ sec 20, T.11N., R.7W. just above the 6200 ft contour and is located by a shaft and an adit symbol on the Ophir Creek 7˝' quadrangle. According to Loen, 1990, the workings here consist of an open cut, two inclined shafts and a vertical shaft, of which only one of the inclined shafts (adit?) is presently open. A sample (POCY-1) was taken yielding assays of 0.017 opt Au, 0.64 opt Ag, 1.85% Cu, 0.02% Pb, and 0.05% Zn. McClernan, 1976 contains a plan map of the Cyclone's workings and Loen, 1990 contains the results of an assay of a sample from this location. Minerals include a blue-green mica (vermiculite according to McClernan, 1976), porphyritic quartz monzonite, malachite, garnet and iron oxide. |
