Comments on the geologic information

  • Geologic Description = Several lode discoveries had been made on the prospect by 1912 including a gold-silver-base metal occurrence on the Your Jim, Big Jim and Our Jim claims which is described here as the Jackson prospect. Development on the Your Jim claims in 1912 consisted of a 60-foot shaft and 30 feet of drifting on the 30-foot level. Mineralization consists of a 26-inch-wide, northeast-striking, 45 degree southeast-dipping shear zone containing 12 inches of white quartz and 8 inches of gouge. Pyrite with gold and silver values is the primary metallic mineral. Two assays conducted in April, 1912 returned values of 5 ounces per ton in gold and 2 ounces per ton in silver, and 19.1 ounces per ton in gold and 9 ounces per ton in silver (Times Publishing Company, 1912). In late 1912, work was being planned to deepen the shaft to 100 feet and begin development drifting at that level. ? By 1913, an adit had been driven on the Your Jim and Our Jim claims for a length of 428 feet in quartzite schist (Chapin, 1914). At the 70-foot station, the adit intersected a thin quartz stringer containing gold and silver of unspecified grade. A series of east-west trending faults which cut the adit also reportedly contained considerable gold. A fault which cuts the adit at the 300-foot station contains abundant sulfides but no free gold (Chapin, 1914). The shaft previously sunk to a depth of 60 feet was abandoned and a second shaft 25 feet south of that point was sunk prior to 1916. This shaft follows a N 45 E, 45 SE shear zone containing galena, arsenopyrite and minor pyrite (Mertie, 1918). By 1916, the adit on the Jackson prospect had been extended to 516 feet and crossed a series of mineralized shear zones. At 70 feet, the adit intersected a N 45 E, 65 NE shear zone. At 123 feet, the adit intersected a N 75 W, 75 SW shear zone. At 200 feet, the adit intersected a N 75 W, 65 SW shear zone. At 300 feet, the adit intersected a N 75 W, steeply southwest-dipping shear zone which exposes a 4-inch-wide crushed quartz stringer containing gold and sulfides. At 380 feet, the adit intersected a N 40 W striking, 45 NE shear zone which exposed an 18 inch wide gouge zone containing silver mineralization (Mertie, 1916). ? the prospect was examined in 1931 by Hill (1933) but had been abandoned for many years at that time. The adit and shafts were caved and only a minor amount of mineralization was exposed on the dumps. This dump material contained pyrite, galena, arsenopyrite, stibnite, jamesonite and free gold along with an unspecified silver-bearing mineral. The Jackson prospect was examined as a possible source of antimony in 1942 but no additional exploration was conducted due to insufficient tonnage potential (Killeen and Mertie, 1951).
