In early April, calibre commenced operations at the Eastern Borosi open pit gold and silver project. The precious metals property is reported to contain 700,500 ounces (oz) of gold and 11.4 million ounces (Moz) of silver "among six epithermal vein-style deposits."
The miner also owns a portfolio that includes three additional precious metals projects across Nicaragua, including the La Libertad mine and mill south of Eastern Borosi.
Ore recovered from Eastern Borosi is being transported to La Libertad for processing.
Darren Hall, president and chief executive at Calibre, expressed his pride in the company's ability to "successfully transform the exploration district to a production centre."
"In April, we began mining from the high-grade Guapinol open pit with a reserve grade of 6.8 grams per tonne gold and ore deliveries to the Libertad mill commenced [in] mid-May," said Hall. "The development of Eastern Borosi marks another significant milestone for the company, which will positively contribute to our grade-driven production growth as we reaffirm our 2023 guidance of 250,000oz to 275,0000oz."
Outside of South America, Calibre also owns the Pan project, a heap leach gold mine in Nevada.
