Mariana Resources has reported the commencement of a 3,500 m diamond drilling program at the company’s flagship Las Calandrias project.
The drill program will specifically examine fresh targets that were discovered nearby, outside and beneath the current Calandria Sur primary resource estimate limits. This program will help in the evaluation of the geological model, which has been amended by the compilation of comprehensive surface mapping, trench and outcrop channel sampling, thorough ground magnetics and re-sampling of the existing drill core. The company’s drilling activity highlights on the capacity for bulk tonnage and high-grade gold mineralization, hosted in the volcaniclastic rocks that enclose the wide Calandria Sur rhyolite dome trending towards the northwest and southeast.
The company will carry out drill testing on two outlier targets. A single hole drilled at the Nido Este prospect will examine a popular NE structural corridor situated near a strong chargeability anomaly. A small erosion window present in the volcanic suite of Pichones uncovered a brecciated chalcedony horizon that may be associated with steam heated alteration above at-depth mineralization. The company has intended to examine the target through two holes. The target has high anomalous gold pathfinder geochemistry and a coinciding high resistivity response obtained from the geophysical survey.
Data obtained from this short drilling campaign will be the base for the design of the extensive program, which will be carried out during later part of 2012.
