Calibre Mining announced the results from two of its ongoing five-trench sampling program on Monday. The exploration is based on its Primavera project in the Borosi property it owns in north eastern Nicaragua. The results of the assays are promising.
Assays from trench PRTR11-005 returned 1.53 grams per tonne gold and 680 parts per million copper over the trench's entire 51.25-meter length. PRTR11-010, found 0.78 g/t gold and 980 ppm copper over 107.0 meters, including 23.0 meters grading 1.03 g/t gold and 695 ppm copper.
The two trenches are located 100 meters apart. The mineralization in them has abundant stockwork veining and the area is expected to be prospective for porphyry related gold-copper mineralization. Work on the remaining three trenches is ongoing.
Douglas Forster, the chairman of Calibre Mining, said that the Primavera gold-copper prospect was a potentially porphyry-related bulk tonnage gold-copper target located within a district that has produced over 5 million ounces of gold and 300 million pounds of copper.
Mr Forster added that they were very encouraged by the initial trench results from this extensive gold-copper system and this new discovery highlights the underexplored nature of the historic "Mining Triangle" in north-east Nicaragua.
The chairman also shared that in addition to the trenching program at Primavera, Calibre Mining had two drill rigs completing a resource delineation drill program at their 100% owned Riscos de Oro gold-silver project located 22 km northeast of the Primavera prospect.
