Calibre Mining (CXB) Corporate Presentation summary

Strategic vision and growth trajectory

• Aims to become a premier Americas-focused gold producer with a path to over 1 million ounces of annual production through expansion and acquisitions.

• Operates eight producing mines and three expansion projects, with significant reserves and resources across North and South America.

• 2024 is highlighted as a transformative year, driven by the Greenstone Mine ramp-up and consolidation.

• Production growth is expected from mine expansions at Greenstone, Aurizona, Castle Mountain, and Los Filos.

• Focus on North American assets is expected to lower costs and increase production scale.

Operational performance and guidance

• 2024 gold production guidance is 655,000–750,000 ounces at cash costs of $1,305–$1,405/oz and AISC of $1,635–$1,735/oz.

• Greenstone Mine is expected to produce 175,000–205,000 ounces in 2024 at cash costs of $690–$790/oz, among the lowest globally.

• Greenstone achieved first gold pour in May 2024 and is ramping up toward full production, with over 60% throughput reached in August.

• Other key mines include Los Filos, Aurizona, Bahia Complex, Mesquite, RDM, and Castle Mountain, each contributing to diversified output.

• Mining at Castle Mountain was suspended in August 2024 for permitting, with residual leaching ongoing.

Asset highlights and expansion potential

• Greenstone is positioned as a cornerstone asset, with a 14+ year mine life, average grade of 1.27 g/t, and expected annual production of ~400,000 ounces for the first five years.

• Greenstone is among Canada’s largest and highest-grade open-pit gold mines, with significant underground and open-pit expansion potential.

• Near-mine and belt-scale exploration at Greenstone and Bahia offer further resource growth opportunities.

• Aurizona is advancing an underground expansion and exploring district-scale targets to extend mine life.

• Consolidation of Greenstone increases production, cash flow, and scale, positioning the company as a top Canadian gold producer.
