Mineros S.A. announced results from the first three drill holes of a follow-up drilling program undertaken by the company's partner at the Guintar-Niverengo Margaritas Exploration Target in Colombia. Drill hole GUI-DD-011 intersected gold mineralized basement rocks belonging to the early-Cretaceous Barroso Formation with low-grade gold (entire drill hole returned 0.2 g/t Au over 400.56 m) disseminated through the hornfels-altered sequence and higher grade intervals (9.8 g/t Au over 1.6 m) related to lithological contacts and more porous conglomerate units. No porphyritic intrusive rocks were intercepted in drill hole GUI-DD-011. Drill hole GUI-DD-012 was collared in lower-grade, gold and copper mineralized mostly chloritic hornfels to 93 m downhole depth, at which point the drill hole passed into a porphyritic intrusive suite, strongly altered with biotite alteration related to quartz-chalcopyrite-pyrrhotite mineralized stockwork veinlets and albite related to chalcopyrite-pyrrhotite mineralized sheeted veinlets. Gold, copper and silver are related to both stockwork and sheeted veinlet styles of mineralization. Not applying a cut off, the entire drill hole GUI-DD-012 returned 320.7 m at 1.1 g/t AuEq from surface. This intersection is the first indication of significant porphyry-style copper and gold mineralization on the Guintar Target Area. Drill hole GUI-DD-013 was drilled below GUI-DD-012 and intersected the biotite-altered intrusive suite with associated mineralization at a down hole depth of 118.0 m. The entire drill hole returned 588.3 m at 0.7 g/t AuEq. Deeper gold-only mineralization (44.0 m at 1.1 g/t Au from 351.0 m) may be related to a more amphibole-rich intrusive suite.
