For mineral collecting - drive N of Bancroft on Hwy 62 for 1.6 ml (from hotel) and turn right on to a dirt road; after 20 yds turn right again. Drive 0.05 ml and park just past the jeep trail leading up the hill on the left. Walk or drive 0.2 ml and park in the left fork. Walk along here, always taking the left trail, for 1,440 paces to the pits . There are other pits down the hill past the first pit on the right (bear right).

Geology Comments

Dec 07, 2005 (C Papertzian) - Uranium mineralization in pegmatites, metasomatic deposits in marble and hydrothermal vein deposits in pyroxenite. 7 main zones (up to 1,900 x 75 ft in area) were identified; zones 2, 3 and 4 show ore grades over narrow widths. Most DDH assays were < 0.005 %, the best were 0.081, 0.183 and 0.128 % over 0.8, 0.3 and 0.4 ft respectively.
