• Near-mine and higher-grade drilling of the Palomino target at Pan Gold mine points to expansion potential;

Darren Hall, President & Chief Executive Officer of Calibre, stated: “The team delivered another record quarter, with production of 68,776 ounces being ahead of budget, and positioning the Company well to deliver our full year production guidance of 250,000 – 275,000 ounces. Importantly, we generated strong free cash flow, increasing the Company’s cash balance 32% over Q1 2023 to $77 million.

During the quarter we announced numerous positive exploration results. Given our demonstrated ability to convert discovery into production, I expect our investment will continue to result in additional shareholder value as we leverage the significant surplus capacity available at the Libertad processing facility.

During the quarter we published our 2022 Sustainability report outlining our progress and achievements as we reaffirm our commitment to transparency, accountability, and responsible mining and business practices.

We believe Calibre continues to present a compelling investment opportunity as we responsibly self-fund discovery and resource expansion, grow production, build reserves, whilst concurrently building cash.”
