Calibre Mining Corp. (TSX: CXB; OTCQX: CXBMF) announces financial and operating results for the three and six months ended June 30, 2024. Consolidated Q2 and YTD 2024 filings can be found at www.sedarplus.ca and on the Company’s website at www.calibremining.com. All figures are expressed in U.S. dollars unless otherwise stated.

Darren Hall, President and Chief Executive Officer of Calibre, stated: “Calibre continues to generate strong operating cash flow, while the fully funded Valentine Gold Mine progresses to construction completion. With the recent approvals for the Volcan open pit and subsequent ore deliveries into the Libertad mill we, as planned, expect a stronger H2 and remain on track to deliver into our 2024 gold production guidance of 275,000 – 300,000 ounces.

During the quarter we made excellent progress advancing the construction of the Valentine Gold Mine with SAG mill, ball mill and primary crusher installation well underway. Pleasingly the team have recently surpassed 2 million hours worked without a lost time injury. A key development recently announced was the receipt of the Federal Environment approval and issuance of Provincial mine and surface leases for development of the Berry deposit and associated infrastructure. With this approval we now have all the major approvals for the current life of mine plan, providing certainty as well as flexibility to optimize for near term cash flow.

We have extensive exploration drilling underway across all our assets. Previously disclosed results at the Valentine Gold Mine indicate robust growth potential below and adjacent to existing Mineral Resources. Consequently, we have expanded the current drill program with 100,000 metres of additional drilling as we begin to unlock the incredible opportunity of resource expansion and discovery potential across the 32 kilometre long Valentine Lake Shear Zone.”

CONSOLIDATED Q2 and YTD 2024 FINANCIAL REVIEW

TCC and AISC for Q2 2024 were $1,264 per ounce and $1,533 per ounce, respectively. The higher cash costs and AISC were due to lower gold production and sales tied to the sequencing of mining different orebodies with lower ore grades, along with higher tonnes moved and higher strip ratios. Q2 2024 gold production was impacted by the geotechnical issue at Limon Norte. The ore tonnes that were not mined in Q2 from Limon Norte are expected to be mined in the second half of 2024.

Net Income

The net income per share in Q2 2024 was $0.03 for both basic and diluted shares (Q2 2023: $0.07 for both basic and diluted). YTD 2024 net income per share was $0.02 for both basic and diluted shares (YTD 2023: $0.11 for basic shares and $0.10 for diluted shares). As a result of the Marathon Gold transaction and C$115 million bought deal financing, the shares outstanding in 2024 increased resulting in the lower net income per share metric.

2024 GUIDANCE

^{* Growth capital excludes the capital being invested in the construction of Valentine Gold Mine}

Calibre’s 2024 guidance reflects, what is expected to be, the fifth consecutive year of annual production growth. Given its proven track record, Calibre will continue to reinvest into exploration and growth with over 160,000 metres of drilling and development of new satellite deposits across its asset portfolio expected in 2024.

Consolidated production is expected to be weighted to the second half of 2024 with Q4 2024 anticipated to be the strongest quarter of the year while TCC and AISC are forecasted to be lower. Production in H2 2024 and Q4 2024 will benefit from the open pit Volcan mine expected to reach commercial production in Q3 2024, higher production from Guapinol and higher Limon and Tigra open pit ore production. Growth capital includes underground development at Panteon Norte, Volcan mine development, waste stripping and land acquisition.

Since acquiring the Nicaraguan assets from B2Gold in October 2019, the Nevada assets from Fiore Gold in 2022, and the Newfoundland and Labrador assets from Marathon Gold in 2024, Calibre has consistently reinvested in mine development and exploration programs. These investments have led to the discovery of new deposits and growth in both production and Reserves. This progress positions Calibre to fulfill its commitments and enhance profitability as it expands its operations in Canada with the Valentine Gold Mine anticipated to deliver first gold during Q2 2025.

The Company’s mineral endowment includes 4.1 million ounces of Reserves, 8.6 million ounces of Measured and Indicated Resources (inclusive of Reserves), and 3.6 million ounces of Inferred Resources, as detailed in the press release dated March 12, 2024.

Notes

(1) NON-IFRS FINANCIAL MEASURES

The Company believes that investors use certain non-IFRS measures as indicators to assess gold mining companies, specifically TCC per Ounce and AISC per Ounce. In the gold mining industry, these are common performance measures but do not have any standardized meaning. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company’s performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

TCC per Ounce of Gold: TCC include mine site operating costs such as mining, processing, and local administrative costs (including stock-based compensation related to mine operations), royalties, production taxes, mine standby costs and current inventory write downs, if any. Production costs are exclusive of depreciation and depletion, reclamation, capital, and exploration costs. TCC per gold ounce are net of by-product silver sales and are divided by gold ounces sold to arrive at a per ounce figure.

AISC per Ounce of Gold: A performance measure that reflects all of the expenditures that are required to produce an ounce of gold from current operations. While there is no standardized meaning of the measure across the industry, the Company’s definition is derived from the AISC definition as set out by the World Gold Council in its guidance dated June 27, 2013, and November 16, 2018. The World Gold Council is a non-regulatory, non-profit organization established in 1987 whose members include global senior mining companies. The Company believes that this measure will be useful to external users in assessing operating performance and the ability to generate free cash flow from current operations. The Company defines AISC as the sum of TCC (per above), sustaining capital (capital required to maintain current operations at existing levels), capital lease repayments, corporate general and administrative expenses, exploration expenditures designed to increase resource confidence at producing mines, amortization of asset retirement costs and rehabilitation accretion related to current operations. AISC excludes capital expenditures for significant improvements at existing operations deemed to be expansionary in nature, exploration and evaluation related to resource growth, rehabilitation accretion and amortization not related to current operations, financing costs, debt repayments, and taxes. Total all-in sustaining costs are divided by gold ounces sold to arrive at a per ounce figure.

Average Realized Price per Ounce Sold

Average realized price per ounce sold is a common performance measure that does not have any standardized meaning. The most directly comparable measure prepared in accordance with IFRS is revenue from gold sales.
