San Simon Gold Recovery Plant

Gold Recovery Team The Company installed and commissioned a 150-tonne per day crushing, milling and flotation gold recovery plant in the Manganeso area to process bulk samples from the 2005 - 2007 underground sampling program on an advance-by-advance or batch basis. The plant and bulk sampling program operated under a 500 tonne per day environmental permit granted from the Bolivian government, thus leaving room for expansion on the existing plant configuration.

The gold recovery plant produced high grade flotation concentrates in the vacuum filter which were then sold to Penoles of Mexico. The plant was designed and supervised by Mineral Processing Consulting Engineer Gary Hawthorn, P.Eng. (B.C.).

The company produced and shipped almost 1,000 ounces of gold and the last batches of bulk sample run through the mill in late 2007 averaged 5 grams per tonne gold and had an average gold recovery of 88%. The simple process or crushing and milling, then floating the gold to a concentrate has demonstrated a simple, productive metallurgy for the gold-bearing rocks in the Trinidad area.

Arial Picture The Doña Amelia gold mineralization is highly oxidized, and both the ore and the plant tailing contain virtually no sulphides. The tailing therefore has no potential to become acid generating.
