There are clear indications of this occurrence in the Wolf Vein that produced 1625 oz of gold by the earlier miners from the vertical greenstone formation that underlies the buried river channels. The Discovery Minerals Geologists will be investigating this greenstone belt. In addition to the well established placer ore that will be mined initially, one of the most exciting features of the Ruby mine is the large greenstone belt formed in the Archean Age that is largely unexplored and is the source of the placer gold. Historically the channels have produced up to 106,000 oz per mile, indicating a potential of 370,000 oz of gold still to be mined from the buried placer. There are 3.5 miles of river channels yet to be mined on the Ruby mining claims. Placer, refers to mining the buried watercourse river bed at Ruby. It is conservatively estimated that 134,844 ounces of gold are available for near-term recovery from identified channels using the existing Ruby infrastructure. The Ruby is also renowned for its production of coarse and jewelers-grade gold, with the largest gold nugget weighing 201 ounces or 17 pounds. It features a system of gold-bearing Tertiary channels which have been reported to have already produced over 250,000 ounces of gold. The Ruby is one of California’s best-known buried placer mines, and is considered by many to be one of the largest producing river channel mines of modern times.
