Summary
Exploration on this 100% Amera-owned, 1700 hectare, porphyry copper-gold project has yielded results from preliminary surface sampling that range up to 1.15% copper over 30.0 meters and 0.74% copper over 50.0 meters.
Work to date by the Company has comprised preliminary mapping, rock and silt sampling focused on the eastern portion of the property in the general area where limited previous drilling was carried out.
Amera is planning a comprehensive surface exploration program to identify drill targets on the core area and to evaluate the remainder of the property.
Location
The property is located in the Southern Department of Cusco, Peru. It lies within the Santo Tomas Porphyry Copper Belt and is located just 8km west of the Company's Cruz de Mayo gold-copper project near the town of Velille. Both properties are located in a prolific mining district known for both epithermal gold and porphyry copper deposits.
The Constancia copper-molybdenum project currently being explored by Norsemont Mining Inc. is located 20km to the east; the high-profile Liam epithermal gold project of Newmont Peru Limited/Southwestern Resources Corp. is located 50km to the southwest; while BHP Billiton's Tintaya copper-gold-silver porphyry-related skarn deposit is located 60km to the southeast.
Technical Background
Claims were held in the Acero area in the past by Southwestern Resources through a joint-venture Southern Peru Copper. They reported discovering two zones of altered feldspar porphyry with potassic alteration and associated leach cap with copper oxides and secondary chalcocite. A limited drill program reportedly intersected "thick zones" of sulphide porphyry copper style mineralization with grades ranging between 0.3 and 0.5% copper with local narrow sections assaying over 1% copper.
Several phases of intrusive have been mapped on the property including dacite, micro-diorite and granodiorite; the majority of mineralization and alteration identified to date is hosted by dacitic intrusive. Quartz stockwork, with individual veinlets up to 3cm wide, is widespread in the southwest portion of the mineralized area. Copper mineralization identified on surface on the Acero property appears to be open to the southeast of current mapping and sampling coverage.
A summary of significant results from the preliminary sampling program is presented below in Table 1. The distribution of the samples is shown on the map accompanying this news.
