Expansion And Discovery Of New Gold Mineralization Zones At the Limon Complex

VANCOUVER - Darren Hall, President & Chief Executive Officer of Calibre Mining Corp., said “The Limon Mining Complex has produced more than three million ounces of gold and continues to present a number of significant opportunities for discovery and resource growth. As underground development at the Atravesada deposit progresses we are pleased with 2021 drill results and believe there is good potential for additional resources that will contribute toward development of new reserves.  We are also encouraged by results of recent drilling below the Tigra open pit which indicate good potential for additional resource growth. Finally, results of first pass drilling at the new Portal vein target located approximately five kilometers northwest of the Limon open pit, again demonstrate the potential for continued discoveries to help drive production and extend mine life.”

Drilling at the Atravesada deposit continues to return high-grade intercepts over significant widths. Importantly, drilling down plunge along the central ore shoot has returned multiple high grade gold intercepts up to 100 meters below the limits of the currently reported underground indicated resource.

Recent drilling at Tigra provides further confirmation of the potential to delineate additional high-grade resources along the main ore shoot as it extends below the current open pit probable reserve. The reserve contains 547,000 tonnes averaging 4.93 g/t Au and 87,000 ounces contained gold1. Additional inferred resources below the open pit reserve include 221,000 tonnes averaging 7.02 g/t Au and 50,000 ounces contained gold.

Drilling along strike and down plunge of the principal ore shoots at Panteon and Santa Pancha 1 has returned additional drill intercepts consistent with the high-grade shoots already delineated at each deposit.

The north-south trending Portal vein lies approximately one kilometer north of Atravesada. First pass drilling intersected near surface mineralization below historic trenching by B2Gold that returned 74.3 g/t Au over 3.8 meters and 9.6 g/t over 2.0 meters. Exploration drilling will continue to test the extent and continuity of gold mineralization both laterally and down dip along the Portal vein.
