Positive Results From Petrographic Study At Abriaqui Highlight Strong Correlation With Important Colombian Gold Deposits

The intrusive system, alteration signature, and mineralization pulses are all multistage which indicates a strong, long-lasting gold-mineralizing system capable of creating a large, multi-million oz deposit.

Results confirm the similarities of the mineralizing system at Abriaqui to the deeper, higher temperature parts of other large, vertically extensive gold-(copper) deposits along the Mid-Cauca trend such as Continental/Zijin’s Buritica Mine and Aris Mining’s Marmato Mine.

The study results place the currently explored portion at Abriaqui above the porphyry gold-(copper) horizon to include the mesothermal vein zone with some hybrid epithermal characteristics in the upper part. High grade vein mineralization at Abriaqui is open below the deepest drilled depths.

The significant vertical extent of mineralization at Abriaqui is similar to the Buritica and Marmato deposits as well as others on the Mid Cauca Gold Belt in Colombia. An idealized vertical section through these deposits shows a mineralized porphyry at the base of the system, grading upward through a 1000 – 1500 vertical meter system of higher temperature mesothermal through lower temperature epithermal veins closer to the surface.

Mineralization in the upper part of the system in the southern block has characteristics of the Carbonate Base Metal (CBM) type gold veins that are well developed in the upper part of the Buritica system.

Results indicate that a significant portion of the gold at Abriaqui is free gold and/or electrum which is not complexed with other minerals. This should significantly enhance future metallurgical recoveries.
