Freeport's Executive Chairman resigns

Freeport McMoRan's founder, James R. Moffett, is resigning as Executive Chairman of the Phoenix-based copper and gold company, according to news reports.   The Wall Street Journal said  "Moffett served as chief executive of the company and its predecessors between 1984 and 2003. He co-founded McMoRan Oil & Gas Co. in 1969 and lead its eventual merger with Freeport Minerals Co. In 1988, under his leadership, the company discovered Indonesia’s Grasberg mine, one of the world’s biggest for gold and copper."    It attributed his resignation to pressure from investor Carl Icahn, and the two-thirds drop in company stock in the past year.

The Arizona Republic stated that "For years, Freeport-McMoRan had been Arizona's most profitable and most valuable corporation in terms of stock-market capitalization. The company was worth around $38 billion as recently as the summer of 2014 but now is worth just $8 billion."

 ·         Satellite imagery of the watershed area including both pre and post-event data.

 ·         A selected bibliography of past USGS reports on abandoned mine lands and natural sources of metals and acidity to streams in the Silverton area.

 ·          A gallery of Gold King Mine photos taken by USGS field personnel the week of August 10, 2015.[modified from the USGS announcement]

The Arizona Geological Survey maintains an interactive web map with sample locations and results from all of the state and federal agencies monitoring the spill and its aftermath, at http://maps.azgs.az.gov/gold-king-mine-spill/.  You can search for any samples that exceeded drinking water standards, and over what time period.

$100 million cost to permit Rosemont copper mine

The permitting process for the Rosemont copper mine south of Tucson will cost $100 million. That figure was reported by Kathy Arnold of HudBay Minerals in a talk today at the annual SME Tucson conference.

HudBay bought out Augusta Resources, former owner of the Rosemont project, in mid-2014 as a result of Augusta's challenge in finding enough resources to complete the permitting process.

Opponents of the mine have been upfront in proclaiming their strategy of dragging out the permitting process as long as possible in order to make it too expensive for the mining company to continue.

The average time to permit a new mine in the US is now 10 years, the longest period among developed countries, and the second longest in the world.
