Atacama Pacific Commences Metallurgical and Geotechnical Drill Program

TORONTO, ONTARIO -- (Marketwired) -- 01/12/17 -- Atacama Pacific Gold Corporation (TSX VENTURE:ATM) ("Atacama Pacific") announces that it has commenced a technical drilling program on its Cerro Maricunga Oxide Gold Project located in Chile's Region III, 140 kilometres northeast of Copiapo. The drilling campaign is designed for the collection of data for the finalization of metallurgical and geotechnical parameters required for the pending feasibility study and will comprise 1,000 metres ("m") of PQ diamond drilling for advanced metallurgical testing as well as 2,000 m of reverse circulation drilling for condemnation and geotechnical information.

Corporately, Atacama Pacific has granted 1,860,000 options of which 1,575,000 were granted to directors and officers and 285,000 were granted to consultants. Each option entitles the holder to acquire one common share at an exercise price of $0.60 until January 11, 2022.

Metallurgical Test Program

The Cerro Maricunga Preliminary Feasibility Study, published August 2014, incorporated plans for three stage ore crushing to a size of approximately two centimetres ("cm") with projected gold recoveries of 79% from a conventional heap leach operation. In support of the upcoming feasibility study, which will consider single stage crushing to a coarser crush size (approx. 10 cm) as part of Atacama Pacific's efforts to reduce capital and operating costs, a metallurgical drilling program has commenced for the collection of ore from each of the three main ore zones (Crux, Phoenix and Lynx zones). Test work will be completed on each zone and at a range of deposit depths.

The current metallurgical program will follow-up the positive results (table 1) achieved from previous column tests conducted on non-agglomerated ore, conventionally crushed to a P80 of 5.0 to 15 cm. To date, thirty-six column tests have been completed on ore from throughout the Cerro Maricunga oxide gold deposit, the majority of which were undertaken on material crushed to a P80 of 1.9 cm and which achieved average gold recoveries of 82%.

Geotechnical Program

Ten reverse circulation condemnation drill holes, approximately 100 m deep, will test the areas to be used for permanent structures, leach pads and waste rock storage. For geotechnical purposes, three 300 to 350 m inclined reverse circulation drill holes, 14 cm in diameter, will be drilled near the final pit walls of each of the main ore zones. Each of the three drill holes will be surveyed with a borehole optical televiewer and, in conjunction with the existing geotechnical information acquired from previous diamond drilling programs, will be used to determine the optimum pit wall angles.

Cerro Maricunga Oxide Gold Deposit

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 with its 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 will be re-costed to reflect current lower input cost for items such as electricity, fuel, labour, metallurgical consumables, equipment, etc.
