Integra Resources Corp. (TSX: ITR) (NYSE: ITRG) is pleased to announce financial and operating results for the three months ended June 30, 2025 (the “second quarter” or “Q2 2025”).

(All amounts expressed in United States (“U.S.”) dollars unless otherwise stated)

Second Quarter 2025 Highlights:

• Mined 3,074,440 tonnes of ore and 2,966,291 tonnes of waste at a strip ratio of 0.96 at the Florida Canyon Mine. The resulting mining rate for the quarter was 33,785 tonnes per day, a 1% increase from Q1 2025.
• Florida Canyon produced 18,087 gold ounces and sold 18,194 gold ounces at a record average realized price of $3,332 per gold ounce.
• Record quarterly revenue of $61.1 million which exceeded Q1 2025 revenue of $57.0 million.
• Record mine operating earnings of $25.2 million, representing a 41% operating margin⁽¹⁾, which exceeded the $15.5 million and 27% operating margin achieved in Q1 2025.
• Adjusted earnings⁽¹⁾ of $11.8 million, or $0.07 per share, which exceeded the $4.4 million, or $0.03 per share in Q1 2025.
• Net earnings were $10.6 million, or $0.06 earnings per share, compared to $1.0 million, or $0.01 earnings per share, in Q1 2025.
• Cash costs⁽¹⁾ of $1,849 per gold ounce sold decreased from $2,016 in Q1 2025. H1 2025 cash costs of $1,936 per gold ounce were slightly higher than the Company’s guidance range of $1,800 to $1,900 per gold ounce but are expected to remain within guidance for the year.
• Mine-site all-in sustaining costs⁽¹⁾ (“AISC”) increased to $2,641 per gold ounce, up from $2,342 per gold ounce in Q1 2025 due to $8.2 million in planned sustaining capital expenditures related to equipment refurbishments, capitalized stripping, and heap leach pad expansions. Increased sustaining capital for the quarter is consistent with the Company’s commitment to re-invest into Florida Canyon in 2025 and 2026 to ensure long-term profitability. H1 2025 mine-site AISC of $2,486 per gold ounce is within the guidance range of $2,450 to $2,550 per gold ounce.
• Operating cash flow of $16.3 million, increased from $16.1 million in Q1 2025 largely from higher metal prices. Operating cash flow before changes in working capital⁽¹⁾ in the quarter was $16.6 million. Both figures are net of the payment of income taxes, which totaled $1.7 million.
• Free cash flow⁽¹⁾ generation was $2.1 million, or $0.01 per share, for the quarter.
• Ended the quarter with cash and cash equivalents of $63.0 million, an increase of 3% from $61.1 million at the end of Q1 2025.

George Salamis, President, CEO and Director of Integra commented: “We are pleased to report consistent gold production from Florida Canyon and positive financial results from the Company for the second quarter of 2025. Florida Canyon continues to deliver on our expectations, generating meaningful cash flow to fund significant re-investment into the mine, while also supporting the Company’s broader growth strategy. Integra’s growing cash balance ideally positions the Company to complete important mine-site capital projects at Florida Canyon including, heap leach pad expansions, capitalized stripping, growth drilling, and mining fleet additions and enhancements. The Company plans to invest over ~$55 million into Florida Canyon this year aimed at near-term improvements and positioning the mine for long-term growth and profitability. The focus for the remainder of 2025 continues to be capital investment and growth at Florida Canyon, permitting advancement and a feasibility study for DeLamar, and continued de-risking activities and advanced study work at Nevada North.”

Mining

In Q2 2025, the Company mined 3,074,440 tonnes of ore from its open pit operations at Florida Canyon, a 2% increase compared to the 3,021,457 tonnes mined in Q1 2025. The Company also mined 2,966,291 tonnes of waste during the quarter, resulting in a strip ratio of 0.96, up from 1,798,502 tonnes of waste and a strip ratio of 0.60 in Q1 2025. The higher strip ratio in Q2 2025 reflects increased capitalized waste stripping aligned with the Company’s re-investment strategy at Florida Canyon, as outlined in its 2025 guidance. Mining rates increased in Q2 2025 compared to Q1 2025, driven by improved mechanical availability of haul trucks resulting from the addition of rental units and optimized haul routes.

In H1 2025, the Company mined a total of 6,095,897 tonnes of ore and 4,764,792 tonnes of waste, resulting in a strip ratio of 0.78. Mining rates are expected to remain elevated in H2 2025 due to continued waste stripping in higher pits, and increased run-of-mine (“ROM”) tonnes placed. This is consistent with the Company’s full year guidance.

Production

In Q2 2025, Florida Canyon produced 18,087 ounces of gold, compared to 19,323 ounces in Q1 2025. Q2 2025 production was lower than Q1 2025 due to a one-time efficiency improvement project that added approximately 2,000 ounces in Q1 2025. Consistent production was supported by the recovery of gold ounces placed on the Phase IIIa heap leach pad during the first half of 2025, as well as residual ounces leached from Phase I and II heap leach pads. During the second quarter 2025 construction of the Phase IIIb heap leach pad at Florida Canyon was initiated, with commissioning expected in late 2025.

During H1 2025 Florida Canyon produced 37,410 ounces of gold, in line with the annual guidance of 70,000 to 75,000 gold ounces. H2 2025 will benefit from higher ounces placed as ROM tonnes increases and from improved grades from the North Pit. Additionally, we expect continued recovery of residual ounces from Phase I and II heap leach pads.

Average process recoveries in the quarter of 60.5% Au, were slightly improved from the 60.4% Au achieved in Q1 2025. Average process recoveries in H1 2025 of 60.4% Au, were in line with expectations.

Capital

In Q2 2025, the Company invested $14.2 million in sustaining capital, bringing total H1 2025 spending to $20.2 million. This reflects the Company’s continued commitment to reinvesting in Florida Canyon through new leach pad construction, increased capital stripping, and mobile equipment refurbishments.

The Company also invested $0.8 million in non-sustaining growth capital during both Q2 2025 and year-to-date periods. This spending was focused on testing lateral extensions and in-pit infill drilling, as well as a nominal amount of waste dump drilling. These expenditures are in line with the Company’s 2025 guidance.

Cash Costs and Mine-site AISC

Cash costs averaged $1,849 per gold ounce in Q2 2025 and $1,936 per gold ounce for the first half of the year.  Mine-site AISC averaged $2,641 per gold ounce in Q2 2025 and $2,486 per gold ounce for H1 2025, aligning with the Company’s 2025 AISC guidance of $2,450 to $2,550 per ounce.

Exploration & Growth

In Q2 2025, the Company initiated a resource growth-focused drill program at Florida Canyon, completing approximately 5,700 meters of drilling by the end of June. The 2025 program was originally designed for approximately 10,000 meters of reverse circulation drilling focused on three key areas: (1) evaluating near-surface oxide potential from historical waste areas; (2) expanding in-situ resources between existing open pits; and (3) testing lateral extensions and conducting in-pit infill drilling. The program is specifically designed to support resource and reserve growth and extend mine life at Florida Canyon. The Company intends to release an updated mineral reserve and resource estimate and an updated life-of-mine plan in H1 2026.

Following the initial success of the drilling, the scope of the program was expanded by approximately 6,000 meters to a total of approximately 16,000 meters, with a focus on historical waste areas.

Program expenditures totaled $1.1 million in Q2 2025 and $1.2 million year-to-date.

Selected Q2 2025 Financial Results

Revenue

In Q2 2025, the Company sold 18,194 ounces of gold at average realized prices of $3,332 per ounce of gold generating record revenue of $61.1 million, compared to 19,540 ounces at average realized prices of $2,888 per ounce in Q1 2025, resulting in revenues of $57.0 million.

Net Earnings

Q2 2025 net earnings of $10.6 million, or $0.06 per share, increased compared to net earnings of $1.0 million, or $0.01 per share in Q1 2025. Net earnings in the quarter were driven by higher realized gold prices which were partially offset by higher taxes driven by improved profitability.

Q2 2025 adjusted earnings of $11.8 million, or $0.07 per share, increased compared to adjusted earnings of $4.4 million or $0.03 per share in Q1 2025. This increase was primarily related to $9.7 million in higher mine operating earnings, partially offset by $2.1 million in reduced transaction and integration costs incurred and $1.2 million in reduced unrealized losses on derivatives.

Cash Flow

In Q2 2025, cash flow generated by operating activities was $16.3 million, or $0.10 per share, an increase compared to $15.7 million, or $0.09 per share, in Q1 2025. Operating cash flow before changes in working capital was $16.6 million or $0.10 per share which compares to $12.3 million or $0.07 per share in Q1 2025.

During the quarter, the Company remitted $1.7 million in tax installments that will be attributable to 2025 payable income taxes. Year-to-date tax payments also totaled $1.7 million.

During the quarter, the Company made payments of $15.0 million for mineral properties, plant and equipment and leases of which $14.2 million was related to sustaining capital expenditures and the remainder related to non-sustaining capital expenditures at Florida Canyon. This increased from $6.0 million of payments made for mineral property, plant and equipment and leases in Q1 2025.

Q2 2025 free cash flow was $2.1 million, or $0.01 per share.

Financial Position

As at June 30, 2025, the Company had a cash and cash equivalent balance of $63.0 million, an increase of $1.9 million from $61.1 million at the end of Q1 2025. The Company also has $15.0 million drawn and $5.0 million undrawn on its convertible debt facility as at June 30, 2025.

The Company’s working capital was $60.1 million on June 30, 2025, reflecting a $3.7 million decrease from March 31, 2025. This decrease was mainly due to the increase in the revaluation of the debt derivative conversion feature and decrease in inventories, partially offset by a build-up in cash from strong operating results.

Development Projects

In Q2 2025, the Company continued to advance and de-risk its flagship development asset, the DeLamar Project located in Idaho. The Mine Plan of Operation for DeLamar is currently under review by the U.S. Bureau of Land Management and cooperating Federal and State agencies. A favorable Determination of Completeness by the BLM will be followed by an environmental review of DeLamar in accordance with the National Environmental Policy Act. The Company expects the environmental review for DeLamar to commence in H2 2025. Concurrently, Integra will work with Federal, State and Local regulatory authorities to obtain all necessary permits for mine construction, operations, and reclamation.

During the quarter, the Feasibility Study for DeLamar was further advanced with mine planning refinements, which include optimizing pit sizing and sequencing to develop the final mine plan for the study. Operating and capital cost estimates will be finalized following the final mine plan. The Feasibility Study results are expected to be released in H2 2025.

During the quarter the Company also advanced the Nevada North Project, which consists of the Wildcat Deposit and the Mountain View Deposit. At Wildcat, metallurgical and humidity cell testing is being completed on core gathered through previous drilling campaigns. The environmental analysis for the Exploration Plan of Operations for Wildcat is complete, indicating a Finding of No Significant Impact, and decision documentation will be complete pending a Memorandum of Agreement with the State Historical Preservation Office and Tribal governments. The Reclamation Permit from Nevada Division of Environmental Protection Bureau of Mining Regulation and Reclamation (“BMRR”) is also in process and anticipated in H2 2025. Hydrological drilling at Wildcat is expected to be completed in H2 2025, initiated under an existing approved Notice of Intent, and completed under additional pending EPO approvals.

Environmental analysis for the Mountain View EPO has also been completed. A Final Environmental Assessment is expected to be published shortly. The NDEP BMRR Reclamation Permit is also expected to be completed imminently.

External affairs efforts for the quarter at the Company’s development projects were focused on regional outreach in Nevada and Idaho, along with federal engagement in Washington, D.C. Following several years of focused engagement on various aspects of the DeLamar Project design, several stakeholder-informed refinements are being incorporated into the Mine Plan of Operations.
