TORONTO, ONTARIO–(Marketwired – Aug. 3, 2017) – Atacama Pacific Gold Corporation (TSX VENTURE:ATM) (“Atacama Pacific”) announces that it has defined the Cerro Maricunga Oxide Gold Project development parameters that will be used during the upcoming feasibility study. While the basic tenets of the 2014 Cerro Maricunga Prefeasibility Study (“2014 PFS”) remain unchanged, the updated parameters include the elimination of the second and tertiary crushers and the removal of the conveyor system with the identification of a new leach pad area located adjacent to the planned open pit.
“As part of the feasibility study process and in conjunction with international mining consultants, we reviewed a number of scenarios aimed at reducing the overall capital requirements while maximizing production”, said Carl Hansen, President and CEO of Atacama Pacific. “With the review completed and a clear path forward identified, we are prepared to commence with a feasibility study for the development of Cerro Maricunga that examines these new parameters”.
Aside from moving to single stage crushing, a new leach pad area was identified in a broad open valley located adjacent to the open pit which will allow for the elimination of the planned six kilometer conveyor system from the pit to the 2014 PFS defined conventional heap leach pad area. The capital requirements of the secondary and tertiary crushers and related infrastructure, including the conveyor system, as outlined in 2014 PFS, were US$130 million. Potential options for further capital reductions will be examined during the upcoming feasibility study.
In support of considering single stage crushing, a series of large diameter diamond drill holes were completed during the first quarter 2017 for further metallurgical testing to confirm the results of previous standard column tests undertaken on 50 to 150 millimeter crushed ore which achieved recoveries of 76% to 80%. The results of the current metallurgical testing, being conducted by Kappes, Cassiday and Associates in Reno, Nevada, are expected during the third quarter.
The upcoming feasibility study will also study the impact of lower input costs for consumables (fuel, lime, NaCN, etc.) and electricity which have fallen in price since the completion of the 2014 PFS. These falling costs, combined with a strengthening US dollar, should help to offset the current lower gold price in comparison to the US$1,350 per ounce price used in the 2014 PFS economics.
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 (NI-43-101 Technical Report filed on SEDAR on October 6, 2014), representing one of the largest undeveloped oxide gold deposits in the world.

FORWARD LOOKING STATEMENTS
This news release contains forward looking statements, including predictions, projections and forecasts. Often, but not always, forward looking statements can be identified by the use of words such as “plans”, “planning”, “expects” or “does not expect”, “continues”, “scheduled”, “estimates”, “forecasts”, “intends”, “potential”, “anticipates”, “does not anticipate”, or “belief”, or describes a “goal”, or variation of such words and phrases or state that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved.
Forward looking statements involve known and unknown risks, future events, conditions, uncertainties and other factors which may cause the actual results, performance or achievements to be materially different from any future results, prediction, projection, forecast, performance or achievements expressed or implied by the forward looking statements. Such factors include, among other items, the timing of the completion of the feasibility study, the impact of proposed updated mining and processing conditions, including crushing and processing methods and mining rates, the results of due diligence activities, changes in economic parameters and assumptions, the interpretation and actual results of current exploration activities; changes in project parameters as plans continue to be refined; the results of regulatory and permitting processes; future prices of gold; possible variations in grade or recovery rates; failure of equipment or processes to operate as anticipated; market conditions, labour disputes and other risks of the mining industry; the results of further economic and technical studies, delays in obtaining governmental approvals or financing or in the completion of exploration, as well as those factors disclosed in Atacama Pacific’s publicly filed documents.
Although Atacama Pacific has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that forward looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements.
