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.
Mineros SA is a Colombia-based company primarily engaged in the exploration and exploitation of gold and other related precious metals, metallic and non-metallic minerals, and hydrocarbons. The Company has its major operational centres in the municipality of El Bagre, as well as in Zaragoza, Nechi and Bajo Cauca Antioqueno, which are located in the department of Antioquia, with a an annual average production of 120,000 gold ounces.
