![Pershimco's Step-out Drilling Results Validate Deeper Copper-gold Potential to the North and Below the La Pava Oxide Gold Mineralization](https://www.goldseiten.de/media/goldseiten-news.jpg)
The south directed, step out drill holes are located on the northern slope of La Pava approximately 175 meters north of the ridge crest and about 100 meters lower in elevation. Higher grade copper-gold-silver intercepts occur at depth within sulphidic hydrothermal breccia lenses in drill holes PDH11017, PDH11018 and PDH11019, with several of these breccia intercepts enveloped by wide margins of 0.25% copper.
The historical RC drilling has tended to cut copper-gold sulphides as primary and supergene copper-gold mineralization just below the oxide zone at LaPava. The new drill hole results, combined with the historical drilling show a strong high sulphidation, copper-gold epithermal system that extends from the surface to depth. The deeper copper-gold sulphide intercepts within hydrothermal breccias continue to suggest the potential for copper-gold porphyry style mineralization at depth (refer to the location map outlining the current and historical drilling at La Pava). Highlights of Pershimco sulphide drilling and historical drilling are as follows:

Gold oxide expansion
The drilling on the northern slope of LaPava, as part of Pershimco's strategy to increase the near surface gold oxide resource, has increased the oxide envelope about 150 meters to the north of the historically defined pit margin.
Alteration PIMA sampling
Initial results of alteration mineralogy utilizing PIMA spectral analyses completed on outcrop and drill core samples demonstrates progressive increasing temperatures from La Pava (lowest temperature, mixed kaolinite-dickite), though Chontal East (dickite only), to La Mesita (crystalline dickite with pyrophyllite). Preliminary interpretation of these results suggests a potential for a higher temperature outflow (mineralization) source towards the Quema/Quemita system to the east. As noted in the previous press release dated September 29, 2011, the Quemita system hosts zones of high grade (greater than 10 g/t) gold oxide mineralization suggestive of near surface feeder structures.
Quality Assurance / Quality Control ('QA/QC')
Drill cores from diamond and RC holes cuts are transported by Pershimco technical personnel from the drill sites to the Cerro Quema Core Shack. There, qualified geologists and technicians log, sample tag and half-split the core in 1 m lengths using stationary saws. The individual sampled intervals of half-split core are then inserted in tagged plastic bag, and sent to the Activation Laboratories (Actlabs) sample preparation facilities in Panama. Individual samples are inventoried by Actlabs personnels, dried, finely crushed to 70% at less than 2 mm, then pulverized to 85% at less than 75 um, and riffle-split to 150 grams. There is 1 Standard, 1 Duplicate and 1 Blank inserted for every 15 samples batch. Samples are then inserted in sealed 5-gallon plastic pails then shipped by courier to the Activation Laboratories main facilities in Ancaster (Ontario, Canada) for assaying using the Muti-element ICP Method and the Pyro-analysis Method with Atomic Absorption Finish for Gold, Silver and Copper. Re-assays are done on samples with results greater than to 2.5 g/t Gold and greater than 10,000 ppm Copper.
