MEXICO – MINEFINDERS CORP. of Vancouver is going ahead with development of the Dolores heap leach project in Chihuahua, Mexico. Construction on the US$131.6-million undertaking is expected to begin next month, with gold production commencing in mid-2007. Minefinders arranged debt financing of up to US$100 million in December 2005.
The open pit with a mining rate of 18,000 tonnes/day, heap leach and gold recovery plant have total direct capital costs of US$98.5 million plus indirect capital costs of US$33.2 million. Production over the 12-year life of the mine will average 160,000 oz gold equivalent. Total cash costs per ounce of gold equivalent are expected to be US$237.70.
Last year, proven and probable reserves at the Dolores project were estimated to be 42.2 million tonnes grading 0.797 g/t Au and 41.8 g/t Ag (or 1.2 million oz of gold and 64.8 million oz of silver). There were also measured and indicated resources of 101.1 million tonnes grading 0.84 g/t Au and 40.8 g/t Ag. Minefinders plans to complete a new resource study this spring. Significant high-grade gold mineralization is also known to occur beneath the outline of the planned pit and may lead to eventual underground mining.
