Colombia Crest Gold Discovers 1.5 Kilometres of Potassic Alteration at the Arabia Porphyry Gold-Copper Target Area, Colombia

19/10/2011 1:45pm

Marketwired Canada


Colombia Crest Gold Corp. (TSX VENTURE:CLB)(PINK SHEETS:ECRTF)(FRANKFURT:EAT)
("Colombia Crest"; the "Company") is pleased to announce that recent rock chip
sampling and mapping at the Arabia target, which lies partially on the Venecia
Project and partially on the Fredonia Project, has resulted in the discovery of
potassic-altered diorite porphyry rocks in outcrop. Porphyry-style
potassic-altered outcrops have been discovered over an area extending more than
1.5 kilometres of strike length in a northeastern trend of outcrops. Ongoing
field work will continue to fill in the areas between these sites at the project
(please click here to view figures:

"We are very excited with the new discoveries of fingers of exposed
potassic-alteration by our geologic team in Colombia. This is critical to
locating the gold-rich zones of a porphyry. Credit goes to our experienced field
crews for finding these exposures, which are limited due to the steep terrain
and thick forest cover, which is typical of Antioquia Province," commented Hans
Rasmussen, President and CEO. "We are also finding that because these samples
are dispersed over such a large area, there is significant size potential to the
Arabia porphyry gold-copper mineralization which is believed to have been
brought to the surface by faults. Because there is a limited amount of outcrop,
we have completed a soil sampling program over almost three square kilometers
where over 1,200 samples were taken. Once we receive the assay results from the
soil sampling, we will have a more complete picture of the distribution of gold
mineralization at the Arabia Porphyry, and from these results our geologic team
can select sites for the upcoming drill program."


A total of 153 rock chip samples were analyzed as part of the first pass
sampling in the Arabia area. Almost all samples were collected in exposures of
bedrock in stream drainages with active flowing streams. Assay results varied
from below detection up to 1.08 grams per tonne gold, up to 1,544 parts per
million (0.15%) copper and up to 17.70 parts per million molybdenum; two samples
show strong correlation of gold-copper-molybdenum. Out of the total samples, 12
returned values greater than 0.1 grams per tonne gold, with five having greater
than 0.5 grams per tonne.


Gold mineralization at Arabia coincides with a stockwork of quartz-magnetite
veins and sometimes traces of chalcopyrite associated with potassic alteration.
Potassic alteration is readily apparent by a pink color tinting the feldspars
and the presence of secondary biotite. Host rocks are fine-grained diorite
composition. The exposures of potassic-altered rocks and thus anomalous
gold-copper assays are almost always associated with faults that are oriented
northeast and vertical. Some of the faults mapped during the sampling are
north-trending. Dikes intrude the dioritic intrusive and they are oriented
east-west and northwest-southeast.


The Arabia target is located 10 kilometres west of Bellhaven's (TSX VENTURE:BHV)
La Mina porphyry gold-copper project and 15 kilometres south of Sunward
Resources' (TSX VENTURE:SWD) Titiribi project. The Arabia Porphyry Complex lies
partially on a concession that is held under the Venecia Agreement with
Colombian Mines Corporation (TSX VENTURE:CMJ) (see news release dated April 5,
2011) and partially on one of the 16 concessions held under the Fredonia
Agreement with Grupo de Bullet (see news release dated August 25, 2011).


As described in a news release dated June 1, 2011, the Arabia area was
discovered as part of our ongoing porphyry gold program focused on the prolific
Middle Cauca Belt, Colombia. A total of 20 highly prospective areas were
identified by Colombia Crest in the Fredonia and Venecia projects. Areas were
defined through the detailed integrating of the airborne magnetic and
radiometric data, along with stream sediment sampling data for gold and copper
values, and the interpretation of geologic maps and fault intersections analysis
from satellite maps. Each of the targets was prioritized for field follow up.
Highest priority was given to targets with the best results from each of the
data groups mentioned above, including mineral title and surface ownership as a
prioritizing criteria. Arabia was one of the first targets visited. Field work
continues on the 34,000 hectares of mineral title. Crews are currently
collecting stream sediment samples and evaluating multiple gold occurrences that
are known to exist on concessions in the Armenia area, located west of Medellin.


All rock samples taken in this preliminary sampling were sent to the ACME Prep
Laboratory in Colombia and sample pulps forwarded to the ACME Lab in Vancouver,
Canada for analysis. 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 better than 85% passing 75 microns mesh. Gold was assayed by fire
assay and atomic absorption using a nominal sample weight of 30 grams with
detection limits of 0.005 to 10 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.
