real finance in the mining industry


The Choco 10 group of concessions encompass approximately 25,000 hectares and are located in the historic El Callao mining district within 5km of the Company's Isidora Mine and 6km from Increible 6 project. The Choco 10 mine and mill facility are located in the western portion of the property where the Company is producing 8,000-10,000 Au ounces per month from established open pits which make up part of a significant gold reserve and resource base which has been developed through the drilling of 270,096m in 2464 drill holes.

The project has excellent access via well maintained roads from the town of El Callao. The project saw 134,000m of drilling in 2008/2009 which was comprised of mostly development work in the form of infill, expansion and grade control drilling around the established deposits to expand and upgrade the current resources. All of the mineralized zones which make up the current resources are open to depth with only approximately 50% of the mineralized areas having been drill tested to date.

The Company has also identified numerous untested targets within 25,000 hectares of prime exploration ground and the Company expects to do between 10,000m and 20,000m of first pass drilling on these targets in 2010.

Concession Geology and Mineralization

The Choco mineral concessions cover oxide and sulphide gold mineralization that occurs in the western portion of the Pastora greenstone belt, which in turn forms part of the Proterozoic to Archaean Guyana Shield.

Primary gold deposits comprise lenses and pods of quartz-sericite altered metavolcanic rock. Shearing has facilitated the deep tropical weathering observed in the region and the development of saprolite to depths of 30 to 70 m. Quartz and sericite enriched gold mineralization is hosted by clay and sericite altered metavolcanic rocks.

The characteristics of gold mineralization at the Choco 10 deposits are varied as a result of a complex interplay between host rock, permeability and geochemistry, proximity to structures and hydrothermal fluid composition. Mineralization is dominantly structurally controlled and is associated with strain partitioning. In general, mineralization is accompanied by carbonate alteration, dominantly ankerite and dolomite, and varying degrees of silica and sericite. Pyrite is the most abundant sulphide phase; it occurs in relatively low concentrations (typically 2-10%) and has a good correlation with gold tenor.
