Partners Intrepid Minerals (IAU-A) and High River Gold Mines (HRG-T) have uncovered silver mineralization at their El Zapote property in western El Salvador.
Six trenches dug in the Cerro Colorado III area returned between 194 grams silver per tonne plus 1.93 grams gold per tonne over 5.2 metres and 358 grams silver over 14.3 metres. Individual samples varied from 25 to 652 grams silver over sample lengths of between 0.8 and 2 metres.
Cerro Colorado III is one of three 80- to 100-metre-high circular hills that characterize an area of silicification 1.3 km in length by 300 to 400 metres in width. The Cerro Colorado III hill has a diameter of 200 metres and is underlain by silicified and argillized clastic sediments.
Intrepid says the zone of mineralization is at least 50 metres in true width. Mineralization is hosted by veinlets of quartz and chalcedony (a cryptocrystalline variety of quartz) containing disseminated pyrite, with the gold mainly associated with sulphides.
Preliminary trenching at Cerro Colorado II, situated 500 metres south of Cerro Colorado III, failed to uncover the zone. However, outcroppings of quartz stockworks and breccias similar to those at Cerro Colorado III were found on the eastern side of the 250- to 300-metre-wide hill.
Trenching and pitting is continuing at all three hills. In addition, a program of geochemical sampling will begin shortly at the past-producing San Casimiro silver-lead-zinc mine, situated 500 metres north of Cerro Colorado III.
The 42-sq.-km El Zapote property is owned 75% by Intrepid and 25% by High River Gold.
