Amera Reports Phase II Drill Results From Central Cocha Project Copper-Silver Zone
|
| |
Amera Resources Corporation (the "Company") (AMS-TSX.V; AJRSF-OTC; OAY-Frankfurt) is pleased to report results for 9 diamond drill holes totaling 1,321m from its Phase II diamond drilling program on the Central Cocha copper-silver zone on its 100%-owned 7,060ha Cocha Project located in Junín department, central Peru. Highlights from the Phase II drill program are provided below in Table I. The most significant drill hole intercept from the 2007 Phase II program includes 37.9m averaging 3.61% copper and 38.2 g/t silver in vertical hole CO-07-20, up dip from mineralization intersected in CO-06-03.
"These results confirm the high-grade nature of the copper-silver mineralization at the Central Cocha zone," stated Nikolaos Cacos, President and C.E.O. "Our focus at Cocha will be to further expand the known high grade copper zones and drill test new targets on the project".
The Phase II drill program will be recommencing once additional permitting, road and drill pad construction have been completed, and will test the South Cocha copper-silver zone in addition to definition drilling on the Central Cocha Zone. In the meantime, the Company is planning IP geophysical studies to define outcropping targets at depth.
The portion of the Phase II drill program reported herein was designed to further delineate the extent of high-grade copper-silver mineralization intercepted in drill hole CO-06-03 (30.23m grading 2.67% copper and 24.1 g/t silver, see October 17, 2006 News Release) and drill hole CO-06-02 as well as in surface trenching (80m averaging 0.80% copper and 10 g/t silver, see January 13, 2006 News Release). As well 6 holes were drilled to test the northwest extent of the Central Cocha (Discovery Outcrop) trend over an additional 600m of strike length.

The Phase II drill program demonstrates the complex nature of the stratabound copper-silver mineralization at Central Cocha and the lenticular shape of the mineralized bodies. To date, six diamond drill holes (CO-06-01, CO-06-02, CO-06-03, CO-07-12, CO-07-17 and CO-07-20) have been drilled along a single northeast-oriented fence to outline the geometric shape and size of the "Discovery Outcrop" area of the Central Cocha Zone. Results delineate a high-grade mineralized body that dips 60 degrees northeast, has an average true width of 22m, a down-dip length of 100m and is closed off 100m along strike to both the northwest and southeast by barren drill holes. The vertical depth of the body extends to 100m depth from surface. In addition, three smaller and lower-grade lenticular mineralized bodies were identified in the hangingwall by the Phase II drilling.
Drill holes CO-07-13, CO-07-14, CO-07-15, CO-07-16, CO-07-18 and CO-07-19 were drilled to the northwest of the" Discovery Outcrop", extending the tested segment of the zone a further 600m to the northwest. Drilling to date has tested the Central Cocha Zone, defined by copper-silver soil anomalies and outcropping mineralization, along 1km of strike length. Further drilling along the Central Cocha Zone will determine the actual strike length of the high-grade mineralized body.
Mineralization at the Central Cocha zone is hosted within deformed lacustrine volcaniclastic stratabound copper-silver zones of the Permian Mitu formation. Chalcopyrite, bornite, chalcocite, cuprite and pyrite are associated with altered carbonaceous agglomerate and ash tuff. Alteration varies from chloritic to silicified and argillic, which patterns suggest a syngenetic genesis of the mineralization. The isolated lenses and variable thickness of the mineralized zones indicate syngenetic structural control, including submarine depressions, growth faults, slumps and debris flows.
Drilling was carried out using a man-portable diamond core drilling rig operated by Pac Rim Drilling of Peru. Core was logged, split and sampled onsite according to NI43-101 standards and care was taken to keep the samples in secure areas. All core was sampled and was analyzed by ALS Chemex laboratory in Lima, Peru using AAS and ICP methods. Additional standard pulp samples were included with the sample submittals for QA/QC purposes and show consistent comparison. Check analysis of the mineralization from the "Discovery Outcrop" Zone in hole CO-07-20 was performed by Acme Analytical Laboratories, with results comparing favorably to those from ALS Chemex. Technical information for this press release is presented by Peter Ellsworth, Vice President Exploration for Amera and a Qualified Person as defined in National Instrument 43-101.
