The work will test a series of high priority targets in two areas within the overall porphyry district.
These are the NE Trend - a 2km by 1km area extending northeast from the existing deposit, and the San Francisco target, which is a 2km by 2km area, centered 3km southeast of the Primavera deposit.
“We are extremely excited to get back drilling on our flagship 100% owned Primavera Gold-Copper Porphyry District," Greg Smith, chief executive of Calibre told investors.
"Calibre’s exploration programs within the five km by four km Primavera target area have identified numerous high priority geochemical, geophysical, and geologic targets which highlight the potential for further gold-copper porphyry discoveries within the Primavera district.
"Porphyry gold-copper deposits tend to occur in clusters and to date Calibre has discovered the first porphyry deposit in Nicaragua that hosts a 1.2 million AuEq ounce resource.”
