Calibre Delivers 71,539 Ounces in Q1 2025, a Record First Quarter Production; Provides Valentine Gold Mine Update

Press Release

VANCOUVER, British Columbia, April 14, 2025 Calibre Mining Corp. (TSX: CXB; OTCQX: CXBMF) (the “Company” or “Calibre”) is pleased to announce operating results for the three months (“Q1”) ended March 31, 2025, and an update on the Valentine Gold Mine (“Valentine”), located in Newfoundland & Labrador, Canada. All figures are expressed in U.S. dollars unless otherwise stated.

Darren Hall, President and Chief Executive Officer of Calibre, stated: “I am extremely proud of our operations team for delivering another strong quarter, producing 71,539 ounces of gold in Q1 2025. Valentine Gold Mine continues to advance, with first ore processed now expected in early Q3, followed by a steady ramp up to nameplate capacity of 2.5 million tonnes. The delay in ore processing reflects scope growth in certain areas such as electrical cabling and actual contractor performance. Valentine is positioned to become a long-life, cornerstone asset in Canada, initially delivering approximately 200,000 ounces of gold annually with significant exploration upside.

In February, we announced a merger with Equinox Gold to form a leading, Americas-focused gold producer. This merger marks a transformative milestone for both companies and will result in a diversified portfolio of operating mines across five countries anchored by Greenstone and Valentine, two high-quality, long life, low-cost, Canadian gold mines. Together, we will become Canada’s second largest gold producer. At nameplate capacity, these Canadian assets are expected to produce approximately 590,000 gold ounces annually, creating significant value for Calibre shareholders and presenting a compelling re-rating opportunity.

Calibre has built a solid track record of delivering on our commitments and driving shareholder value. I see a tremendous opportunity to integrate the two companies, build on this success, and strengthen trust and confidence across both shareholder bases. New Equinox Gold has the potential to exceed 1.2 million ounces of annual gold production with Greenstone and Valentine operating at capacity. Additionally, the combined company will benefit from a large gold endowment of Mineral Reserves and Mineral Resources, along with a robust pipeline of development, expansion, and exploration projects. This strong foundation supports low-risk sustainable growth and long-term value for shareholders.”

Q1 2025 Highlights

• Consolidated gold production of 71,539 ounces; Nicaragua 64,469 ounces and Nevada 7,070 ounces, setting a solid foundation for the remainder of 2025;
• Cash of $214.5 million at March 31, 2025 ($177.4 million in cash and $37.1 million in restricted cash with the last $25 million restricted cash released from our debt proceeds account following quarter end); and

  • Enhanced critical mass and capital markets profile with improved significance for shareholders,
  • Immediate increase in production and cash flow from a larger asset portfolio,
