Agency: NF Region District: R1 Ranger District: LINCOLN Forest Service Tract: Watershed Code: 17010203 Forest or Resource Area: HELENA Owner: N Impact: V Report: Oker Mine LC007296 This group of mines has affected the entirety of Sandbar Creek with orange, iron staining. Flow above the easternmost adit appears normal. There are three -possibly four- totally caved adits, none with discharges. The creek cuts across the waste dump of the middle adit; the upper and lower adits both have streamside wastes. One pile of ore sits on timbers and is apparently an attempt at an open-roasting set-up or an ore loading platform. A road has been constructed across the middle waste dump and adjacent to this area the streambed has been placered (?). A select sample along 125' of colluvium in the westernmost adit (PBLOM-1) assayed <0.0005 opt Au, 0.65 opt Ag, 0.02% Cu, 0.06% Pb, and 0.001% Zn. Another sample, a composite from the easternmost waste dump (PBLOK-2), ran 0.087 opt Au, 2.15 opt Ag, 0.05% Cu, 1.05% Pb and 0.20% Zn. This dump is adjacent (within 10 feet) to Sandbar Creek but no active erosion was noted. A third sample composited from the waste dump of the middle adit (PBOKM-1) assayed 0.006 opt Au, 0.68 opt Ag, 0.05% Cu, 0.28% Pb, and 0.03% Zn. These mines are located primarily, if not entirely, on HNF land. There is a file in the MBMG files on "Sanborn" Creek which fits the description of Sandbar Creek but the occurrence described is a manganese one and samples from the mines described above are not anomalous in manganese. The two occurrences may or may not be related. |
