Atacama Pacific Reports Cerro Maricunga Phase IV Drill Results
114 Metres Grading 0.93 g/t Gold Including 1.75 g/t Gold over 30 Metres
TORONTO, ONTARIO -- (Marketwired) -- 04/12/13 -- Editors Note: There is an image associated with this release.
Atacama Pacific Gold Corporation (TSX VENTURE: ATM) ("Atacama Pacific") is pleased to report further Phase IV drill results, including 114 metres grading 0.93 grams per tonne gold ("g/t Au") with a higher grade interval of 1.75 g/t Au over 30 metres, from its 100% owned Cerro Maricunga oxide gold project located in Chile's Maricunga Mineral Belt. Table 1, attached, summarizes the current drill results and figure 1 presents the location of the drill holes.
Diamond drill hole CMD-262, cored into the centre of the Lynx Zone cut four intervals of oxide mineralization including 24 metres grading 0.28 g/t Au, 46 metres grading 0.32 g/t Au and 80 metres grading 0.53 g/t Au followed by 0.93 g/t Au over 114 metres which expanded the dimensions of the higher grade area on section 2350 previously intersected by CMR-124 (60 m @ 0.91 g/t Au).
Reverse circulation drill holes CMR-271 (3 intervals including 78 m @ 0.42 g/t Au - section 950) and CMR-294 (100 m @ 0.33 g/t Au - section 1050 Au) returned significant intervals of +0.3 g/t Au mineralization in an area located between the Crux and Phoenix Zones previously modelled as barren. These holes follow up on two drill holes (CMR-239 and CMR-241 released January 17, 2013) located on section 900 which, when taken together, outline a new area of east-west trending oxide gold over a strike length of approximately 150 metres and widths of over 100 metres.
The drilling component of the Phase IV campaign has now been completed and mapping, surface channel sampling and metallurgical sampling will continue through early May. Originally planned for 20,000 metres of drilling, the identification of additional infill targets within the Cerro Maricunga deposit necessitated increasing the program to a total of 27,200 metres. In addition to infill drilling, condemnation holes were drilled in the leach pad and plant area and a sixth water monitoring well was also completed.
The goal of the Phase IV drilling program is to convert inferred category resources, located within the US$1,400 pit shell outlined in Atacama Pacific's recently released preliminary economic assessment (released January 28, 2013), to the measured and indicated categories. Overall, the current results of the Phase IV campaign have confirmed the interpretation of the resource model with the exception of the Pollux Zone where the mineralization is orientated in an east-west direction compared to the general northwest trend of the main deposit. Changes in the Pollux Zone interpretation are not expected to have a significant impact on the Cerro Maricunga resource estimate.
Final drill results should be available by June 2013 with an updated resource estimate planned for the third quarter of 2013 after which Atacama Pacific will commence feasibility work.
Metallurgical Update
As part of the continuing development of the project, a further 14 column and 34 bottle roll tests have been completed at Kappes, Cassidy and Associates' extractive metallurgical laboratory in Reno, Nevada. The test work focused on low to average grade mineralization from the three main gold zones typically crushed to 19 millimetres. The final results from the testing are anticipated this month.
Santa Teresa Drilling
Atacama Pacific recently completed three reverse circulation drill holes (1,450 m) targeting a strong chargeability anomaly identified from a recently completed induced polarization survey. The Santa Teresa property is located within the northwest corner of the Cerro Maricunga property, 8 kilometres northwest of the Cerro Maricunga deposit. All three drill holes intersected intervals of disseminated pyrite and fragments of quartz veining were noted in the reverse circulation chips. The chargeability anomalies are associated with magnetic highs and overlie a series of trenches which have returned anomalous gold grades.

FORWARD LOOKING STATEMENTS
This news release contains forward-looking statements, including predictions, projections and forecasts. Forward-looking statements include, but are not limited to the success of exploration activities generally, mine development prospects, and potential future gold production. 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 others, 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; 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. Accordingly, readers should not place undue reliance on forward-looking statements.
