Orosur Mining Inc. said Jan. 19 that it completed a preliminary geological model for the Aragon-Pastorera trend area of its Anzá gold project in Colombia, based mainly on 17,408 meters of existing diamond core drilling data from 53 holes previously drilled.
Based on the results, the gold potential of a portion of Aragon-Pastorera is estimated to range from 1.6 million to 2.3 million tonnes averaging between 3.2 and 3.7 g/t of gold.
The estimate is based on current drilling and is expected to grow as future exploration drilling is conducted.
The mineralized zones in the area are believed to continue, both at depth and at the surface, to the north and south of the limited area that has been analyzed to date and included in the preliminary model.
The Aragon-Pastorera area extends 2 kilometers along the strike of the vein-like deposit, but only accounts for a small portion of the total Anzá project, which covers about 105 square kilometers in total.
Additionally, the company plans to undertake a drill campaign comprising 15,000 to 30,000 meters of drilling during 2017, to delineate maiden resources for Anzá and further define and expand the potential mineralization for the Aragon-Pastorera area.
Drilling will also test mineralization in undrilled areas of the deposit where strong indications of economic gold occurrences exist.
