Ed,

My research continues. I have looked at every annual report from the Bureau of Mines and the US Geological survey and the US mint and others that I could get my hands on. The only mention of the Oro Grande I can find is from The Arizona State Mine inspector in 1934 and 1935. At that time there was some short lived activity that resulted in no production but rather some speculative development.

These reports are very detailed in that they even mention miners recovering gold by crushing ore in mortars and amalgamating. They report shipments as small as five ounces of gold for the year.

The mint in San Francisco mentions receiving small shipment of bullion from porducers and then separating the gold from the silver and using both for coin production. No mention of any penalties. The only platinum production mentioned is from placers in CA, OR and WA. This was all shipped to refiners back east.

It might be that the Oro Grande was part of the Vulture Mining District, (which shut down in 1917.) Do you know if the Oro Grande had a different name? I do have references to some articles written in the Engineering and Mining Journal about the Vulture in 1922. I will attempt to find these next week. I think the NMT library has a complete set of old EMJ's.

Can you find infor about the name?
