Atacama Pacific Gold Corporation (TSX VENTURE:ATM) ("Atacama") is pleased to report the commencement of Phase IV drilling activities on its 100 owned Cerro Maricunga Oxide Gold Project located in Chile's Maricunga Mineral Belt.
The drilling component of the Phase IV campaign will comprise 20,000 metres with 15,000 metres of infill drilling dedicated to upgrading current inferred resources to the measures and indicated category and 5,000 metres directed towards exploration. In addition to drilling, the Phase IV program will include continued metallurgical test work, with 15 column percolation leach tests presently underway, along with engineering studies and the collection of environmental baseline data in support of future permitting. The budget for the Phase IV program is approximately US$23 million.
Atacama's Cerro Maricunga preliminary economic assessment ("PEA") is now scheduled for release in January 2013. The results of the PEA will establish the benchmark engineering parameters and capital expenditures for a mining and heap leach processing operation at Cerro Maricunga.
Water Exploration
Drilling for aquifer water has commenced on a series of contiguous water exploration concessions covering 267,000 hectares. The concessions are located approximately 95 kilometres north of Cerro Maricunga. Drilling is focused on a number of possible aquifers outlined during last season's geophysical survey program. The water drilling program, which is included in the Phase IV budget, is planned to be completed during the first quarter 2013 at which time the wells will be pump tested to determine potential water flow rates.
Technical Report Filed
In support of the recently announced Cerro Maricunga resource update, Atacama recently filed a National Instrument 43-101 compliant technical report on www.sedar.com. The measured and indicated ("M&I") resource at Cerro Maricunga is presently 2.667 million ounces of gold in 163.9 million tonnes grading 0.51 grams per tonne gold ("g/t Au"), at a 0.3 g/t Au cut-off, with a further 1.810 million ounces of gold in 120.7 million tonnes grading 0.47 g/t Au in the inferred category.
National Instrument 43-101 Compliance
The Cerro Maricunga resource estimate was prepared under Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards (2005). Dr. Eduardo Magri, a mining engineer (University of Witwatersrand) and a Fellow of the Southern African Institute of Mining and Metallurgy with over 30 years of industry experience, is the independent qualified person, as defined by National Instrument 43-101, for the resource estimate. Dr. Magri has reviewed and verified the contents of this press release. NCL Ingeneiría y Construcción Ltda. undertook to prepare and is responsible for the resource estimate under the supervision of Dr. Eduardo Magri and Antonio Couble (NCL Associate).
