CALIBRE EXERCISES ITS RIGHT TO BUY BACK 1% NSR AT ITS 100% OWNED EASTERN BOROSI MINE

Calibre Mining Corp. is exercising its right to purchase 50 per cent of the production royalty, 1-per-cent net smelter return (NSR), for $2-million (U.S.) from Triple Flag Precious Metals Corp., at its 100-per-cent-owned Eastern Borosi project, thereby reducing the existing royalty to a 1-per-cent NSR.

Darren Hall, president and chief executive officer of Calibre, stated: "I am pleased with the progress being made at the Eastern Borosi mine with the team being on time and on budget with the start of our high-grade open-pit mining operation. We believe there is excellent potential to expand resources and make new discoveries that will provide additional runway for future gold production growth. Based on demonstrated execution and upside growth potential at Eastern Borosi, it makes good sense to exercise this right given the anticipated high return on investment."
