Colombia Crest Gold Announces Initial Assays From The Drill Program At The Arabia Porphyry Gold Complex, Colombia
Including 34 metres of 0.55 grams per tonne gold and 32 metres of 0.57 grams per tonne gold
October 17, 2012 VANCOUVER, BC - Colombia Crest Gold Corp. (“Colombia Crest”; the “Company”) (TSX-V: CLB; Pink Sheets: ECRTF; Frankfurt: EAT) is pleased to announce the latest results from its ongoing exploration program in the Middle Cauca Belt, Colombia. Initial Phase 1 drill results from the Arabia Porphyry Complex have returned typical porphyry system grade including 182 metres of 0.38 grams per tonne gold (g/t) in drill hole AR12-4, including several higher-grade intervals. A total of eight drill holes have been fully analyzed and are reported today – the remaining nine holes will be reported once final assays have been analyzed and received.
“Based on the consistent gold grade, alteration, and the presence of mineralized host rocks with mineralized intrusive, our geological team believes that all holes drilled to date have cut the uppermost portions of a large porphyry gold-copper complex," commented Hans Rasmussen, President and CEO. “Looking at these initial results, we are seeing significant size potential as we test over 1.5 kilometres of strike length at four different porphyry gold targets and mineralization remains open in all directions. Having drilled angle holes up to 440 metres to depth, our analysis of all assays will guide a follow-up drill program to focus on reaching 1+ g/t gold, with deeper, vertical holes.”
|Drill Hole||From (m)||To (m)||Length (m)||Au g/t||Cu %|
|AR12-7||no intervals exceed minimum criteria|
Minimum criteria are a 0.10 g/t Au cut-off grade, 6 metre length, and no sub-intervals below cut-off that exceed 4 metres.
Intervals noted “* Including” use a 0.3 g/t Au cut-off grade.

The first two holes were drilled into gold-mineralized hydrothermal breccia while hole 3 was our first indication of mineralized porphyry. All subsequent holes cut mineralized porphyry, and magmatic and tectonic breccias of varying degrees of alteration, all related to a strong mineralizing system extending over 1.5 kilometres of strike length. The mineralized zone remains open-ended in all directions. The best gold grades noted so far are associated with potassic alteration, which may include quartz-magnetite plus pyrite and chalcopyrite along with potassium feldspar and secondary biotite.
Based on geologic logging, petrographic interpretation of selected intervals of core and review of the trace element geochemistry, as well as the consistent gold grades in the results to date, Colombia Crest’s geological team believes that the porphyry gold-copper system extends to depth, with deep vertical holes being the focus of a follow-up drill campaign at Arabia. Alteration and the presence of multiple mineralized intrusives also suggest that we are drilling the upper levels of a porphyry system.
The Arabia area is located just 10 kilometres west of Bellhaven Copper and Gold’s (TSX-V: BHV) La Mina project and 15 kilometres south of Sunward Resources' (TSX-V: SWD) Titiribi project. The Arabia Porphyry targets lie partially on a concession that is held under the Venecia Agreement with Colombian Mines Corporation (TSX-V: CMJ) and partially on one of the 16 concessions held under the Fredonia Agreement with Grupo de Bullet. In early 2011, a grass roots exploration program began at Arabia, after the target was selected from 20 porphyry targets identified in the Fredonia-Venecia concessions; all were based on interpretation of airborne geophysical data and geological information. Three other targets will be explored in late 2012 into 2013; including two targets called Garrucha and a third called Margarita (see the Company’s website for more details on these targets).
All drill core samples were cut and sampled over nominal two-metre intervals at the Company's on-site field camp, then sent to the ACME Prep Laboratory in Medellin, Colombia. The chosen preparation method was Preparation Code R200-250, which consists of a 1 kilogram sample crushed so that 80% passes an 800 micron mesh (0.8 millimetres), which is then split and 250 grams are pulverized to at least 85% passing 75 microns mesh. Once prepared, 250-gram pulps were forwarded to the ACME Lab in Vancouver, Canada for analysis. Gold was assayed by fire assay and atomic absorption using a 30 gram assay charge with a detection limit of 0.005 parts per million. A multi element package of 41 elements including silver, base metals and pathfinder elements was also analyzed using ICP mass spectrometry. The ICP multi-element analysis uses a four-acid digestion prior to analysis.

Porphyry System Characteristics
Porphyry gold systems host very large, bulk tonnage deposits that range from 2 to over 20 million ounces of gold and typically grade from 0.5 to 2 grams per tonne. Thus, major mining companies seek out porphyry deposits for their large scale and long mine life. Investments by major mining companies have been announced in the Middle Cauca Belt, demonstrating a growing focus on Colombia as a source for new long-life gold mines.
