•California Wilderness Coalition and the Nature Conservancy Recruit Government Employees to Carry Out Huge Land Grab--US Geological Survey, US Forest Service, Bureau of Land Management and California State Employees Attend Environmental Extremist Conference

ICMJ has obtained a copy of the conference roster and the sponsors list. It's very disturbing to see both the US Geological Survey and California State Parks listed as sponsors after our elected officials declined to endorse the Treaty.

•Drywashing Rules Clarified

The 43 CFR 3809 Final Rule previously stated that hand and battery-operated drywashers were to be considered under the "casual use" provision, but there was no mention of gas-powered drywashers. This led to much debate among prospectors and BLM staffers.

•Mineralized Calderas in Colorado

Gold, silver, and base metals have been mined, but calderas could contain many other valuable metals as well.

•The Keystone Gold-Copper District, Medicine Bow Mountains, Southeastern Wyoming 

by W. Dan Hausel, Senior Economic Geologist, Wyoming Geological Survey

Most deposits in the Keystone region are gold- and copper-bearing pyritic quartz-carbonate veins found within northwest-trending tensional faults. Some sparse mineralization is also found within some northeast-trending shears (Currey, 1965).

•The Phoenix Gold Mine: A Brief History

by Sam E. Phifer, PG

Not only  was the Phoenix mine noted for the size and richness of its vein, but also due to the fact that a German mining engineer named Adolph Theis developed the chlorination process here in about 1889. The process, which I'll discuss in detail later on, enabled the early miners to successfully treat sulfide gold ore and to recover a substantial amount of the values that would have otherwise been lost.

•Calico Mine

by Reggie Gould

The tunnel opened into a huge underground room, and the eerie part was that there were people in this room--lots of them--and they were frozen in time. The hair stood up on the back of my neck.
