Atacama Pacific Reports Positive Cerro Maricunga Drill Results Including 224 Metres Grading 0.62 g/t Gold and 96 Metres at 1.07 g/t Gold
TORONTO, ONTARIO -- (Marketwire) -- 04/07/11 -- Atacama Pacific Gold Corporation (TSX VENTURE: ATM) ('Atacama Pacific') announces continued positive drill assay results from its 100%-owned Cerro Maricunga Gold Project, located 20 kilometres south of Kinross Gold's La Coipa Mine in Chile's Region III. Current drilling confirms the continuity of the oxide-associated gold mineralization in the Phoenix and Lynx zones as well as extends the mineralization to depth. Table 1 summarizes the gold assay results and an attached map shows the drill hole locations.
Highlights from the recent drilling include:
-- 180 metres grading 0.60 grams per tonne gold ('g/t Au') from drill hole
CMD-038;
-- 156 metres grading 0.80 g/t Au including 1.07 g/t Au over 96 metres
(CMR-045);
-- 238 metres grading 0.67 g/t Au including 1.10 g/t Au over 62 metres
(CMR-049);
-- 224 metres grading 0.62 g/t Au including 1.16 g/t Au over 30 metres
(CMR-054); and
-- 126 metres grading 0.67 g/t Au including 1.38 g/t Au over 14 metres
(CMR-062).
'These positive drill results confirm our expectations that the Cerro Maricunga project hosts a large oxide-associated gold deposit which metallurgical test work has confirmed is amenable to heap leaching,' said Carl B. Hansen, President and CEO of Atacama Pacific. 'With the expanded Phase II drill program coming to an end this month, the first Cerro Maricunga NI 43-101 compliant resource estimate is anticipated to be reported during the third quarter 2011. This resource estimate will provide the foundation to accelerate Cerro Maricunga's development.'
Phoenix Zone Drilling
Drilling on the Phoenix Zone continues on 50 metre sections in preparation for the Q3 resource estimate. Current results were largely as anticipated with key infill holes CMR-045, CMR-052 and CMR-054 returning long intervals of 0.3 g/t Au with significant intervals of 1 g/t Au mineralization including 96 metres grading 1.07 g/t Au (CMR-045). Three drill holes tested the southeast contact area with CMR-047 and CMR-062 ending in mineralization of 0.63 g/t Au and 0.47 g/t Au respectively.
Lynx Zone Drilling
Recent drilling significantly widened the Lynx Zone on sections 2300 and 2200. Drill hole CMD-038, which returned 180 grading 0.60 g/t Au, widened the Lynx Zone to approximately 250 metres extending the mineralization towards the top of the northern peak (see attached map). Drill hole CMD-049, which returned a 238 metre interval of 0.67 g/t Au, widened the Lynx Zone to 200 metres. The 238 metre interval from CMD-049 also included a higher grade zone of 62 metres grading 1.10 g/t Au with 24 metres grading 1.98 g/t Au.

Exploration Program Update
The Cerro Maricunga Phase II drill program is progressing better than planned with 27,500 metres completed exceeding the previously expanded budget of 25,000 metres. Two reverse circulation drills will continue to operate until the onset of winter, which is anticipated by mid-April. All assays from the drill program should be processed by the end of May.
Approximately three tonnes of mineralized material from Cerro Maricunga is being prepared for shipping to North America for metallurgical testing. Results from the metallurgical testing will be used to assist in establishing parameters for an economic assessment of the Cerro Maricunga oxide-associated gold deposit.
About Atacama Pacific Gold Corporation
Atacama Pacific's principal business is the acquisition, exploration and development of precious metals resource properties in Chile. Atacama Pacific's principal mineral property is the Cerro Maricunga oxide-associated, breccia-hosted gold project, located in Region III, 140 kilometres by road northeast of the city of Copiapo. Atacama Pacific's goal is to become a producer of gold through the exploration and development of the Cerro Maricunga Gold Project. Atacama Pacific also owns four other mineral properties within close proximity to the Cerro Maricunga Project and a fifth property in Chile's Region I.
Quality Control / Quality Assurance Program
RC chips and diamond drill core from Atacama Pacific's drilling campaign were collected at the drill under the direct supervision of Atacama Pacific staff. Both the RC samples and drill core were appropriately tagged, secured and transported to the Atacama Pacific exploration camp and then to Atacama Pacific's secure sample, logging and storage site in Copiapo, Chile. Each RC chip sample was split to obtain a 15 kilogram sample for assay purposes. Representative chips were collected from each sample for logging purposes. Drill core was logged, marked at two metre intervals for sampling and split longitudinally with a diamond drill saw. One half of the core was bagged and sample tags attached and the second half of the core was returned to the core boxes. All samples were appropriately tagged and sent to Asesoria Minera Geoanalitica Ltda.'s ('Geoanalitica') sample preparation facility in Copiapo. Resulting pulps were then returned to Atacama Pacific's storage facility in order to insert QA-QC pulps and re-numbering (bar codes) before being transported by Atacama Pacific personnel to Activation Laboratorios Ltda. ('Actlabs') in Coquimbo, Chile for analysis.
Samples were analyzed for gold using fire assay techniques using two assay/ton samples (about 50 gram) with an atomic absorption spectrographic finish for a sensitivity of 5 ppb (.005 ppm) gold. Approximately 10% of the samples submitted to Actlabs comprise field rejects for RC chip samples, coarse rejects for drill core, pulp duplicates, standard and blank samples to ensure laboratory quality control procedures.
