Calibre Mining Corp. (TSXV:CXB) reported that it has received complete assay results from the initial two trenches excavated on the newly discovered Primavera gold-copper prospect on the Borosi project, Nicaragua.

As quoted in the press release:

Both trenches intersected continuous gold and associated copper mineralization over their entire excavated lengths. Weighted averages for the trenches include; Trench PRTR11-005 assaying 1.53 g/t Au and 680 ppm Cu over 51.25 metres (open) and Trench PRTR11-010 assaying 0.78 g/t Au and 980 ppm Cu over 107.0 metres (open) (see Table 1 below).

The two trenches are located approximately 100 metres apart with PRTR11-005 trending east-west and PRTR11-010 trending north-south. The trenches are part of a series of five recently excavated trenches located within an 850 metre by 300 metre coincident gold-copper soil anomaly in a region with very limited rock exposure. Mineralization in the trenches is characterised by abundant stockwork veining and the area is thought to be prospective for porphyry related gold-copper mineralization. The mineralized interval in the trenches is open in both directions and the trenching and sampling program is on-going.

Calibre’s Chairman, Douglas Forster stated:

“The Primavera gold-copper prospect is 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. We are 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 northeast Nicaragua. In addition to the trenching program at Primavera, Calibre has two drill rigs completing a resource delineation drill program at our 100% owned Riscos de Oro gold-silver project located 22 km northeast of the Primavera prospect.”
