Atacama Pacific Gold Corporation (TSX VENTURE:ATM) ("Atacama Pacific") is pleased to announce that the technical drilling program at its Cerro Maricunga Oxide Gold Project has finished with 700 metres of metallurgical drilling in three PQ drill holes and 1,860 metres of reverse circulation technical drilling completed.
Samples from the metallurgical drilling program are being shipped to the Kappes, Cassidy and Associates' facility in Reno, Nevada for column test work. The purpose of the metallurgical testing is to confirm the 72% to 80% gold recoveries achieved from previous conventional column tests completed on oxide ore crushed to five, ten and fifteen centimetres. The planned feasibility study will consider single stage crushing to a coarse crush size (~10 cm) as part of optimization efforts.
The technical drilling was undertaken to collect geotechnical data to determine pit wall angles as well as for condemnation purposes in the areas of planned development. The program included three large diameter drill holes which will be surveyed with a borehole optical televiewer within the next few weeks. The data will be incorporated with the existing geotechnical information to determine the optimum pit wall angle in an area where limited geotechnical information was previously available.
The Cerro Maricunga oxide-associated, breccia-hosted gold deposit hosts total Proven and Probable mineral reserves of 294.4 million tonnes grading 0.40 grams per tonne for 3.74 million ounces of gold representing one of the largest undeveloped oxide gold deposits in the world. Before commencing a feasibility study, Atacama Pacific is reviewing development options for Cerro Maricunga with the goal of reducing capital and operating costs through the elimination of the secondary and tertiary crushers, by using valley fill leaching at a location adjacent to the open pit and by commencing operations at a lower production rate of approximately 40,000 tonnes per day over the first years of production ramping up to 80,000 tonnes per day. The project also will be re-examined in light of current lower input costs for items such as electricity, fuel, labour, metallurgical consumables, equipment, etc.
Atacama Pacific also announces the appointment of Spinnaker Capital Markets Inc. ("Spinnaker") as its capital markets and investor relations advisor. Spinnaker's mandate is to focus on developing and expanding the network of investors, analysts, and financial intermediaries who are interested in following the Atacama Pacific growth and investment story. The appointment is for a term of six months and provides for a range of advisory services for a monthly fee of $7,000. The related agreement is subject to the acceptance of the TSX Venture Exchange.
