Massive Sulfide Layer reported in Kinross Gold Corporation / Geocom Resources Inc. Espolon Mine claim in the Futaleufu Valley - AMD hazzard imminent

In April 2007 Kinross Gold Corporation and Geocom Resources Inc. reported initial assays for their Espolon Gold Mining Claim in the Futaleufu River Valley watershed. The results were as follows:

"The Espolon Claim Block comprises 13 claims totaling 3,800 hectares (9,390 acres or about 14 square miles). The claims cover a gold-silver-copper mineralized zone that has now been traced over a strike length in excess of 3 kilometers (2 miles). The mineralized zone is 10 to 30 meters thick (32 to 96 feet). The zone consists of a gently dipping altered sequence of volcanic tuffs, limestones, and argillites. These rocks have been thermally metamorphosed and moderately to completely silicified. Within the mineralized zone there is a massive sulfide layer that varies in thickness up to 3 meters (about 10 feet) consisting of pyrrhotite-pyrite with varying amounts of chalcopyrite. " Reference: Yahoo Finance, Espolon Assays...

The Geocom Resources geologists reported a "MASSIVE" SULFIDE LAYER within the mineralized zone. These layers, even when small in size, are associated with Acid Rock and Acid Mine Drainage (ARD/AMD), the industry's terms for the production of sulfuric acid run-off. Pyrrhotite-pyrite (FeSx, iron sulfide) and chalcopyrite (CuFeS2, Copper Iron Sulfide) , which were specifically mentioned, are both associated with Acid Rock Drainage (AMD).

Sierra Club: Sulfide Mines with Acid-Producing Tailings (Waste Rock Piles)

"Another threat to the environment is the mining and processing of copper, nickel, platinum, palladium, rhodium, silver and gold found in low concentrations in rock with sulfides that turn to sulfuric acid (battery acid) when exposed to air and water — as they are when they are mined. The result is mountains of waste rock (99+% of mined rock would be waste) that are expected to leak acid for unknown decades. The acid kills aquatic life that feed fish and amphibians, leaving the rivers and downstream lakes barren and unsafe. Water draining from the waste rock also (with or without acid) will leach toxic metals such as cobalt into the waters.

After the mines play out, the perpetual costs of treating polluted drainage and tending toxic wastes could fall on taxpayers because sulfide mines are "reactive" or acid producing for thousands of years." Reference: Sierra Club
