VANCOUVER, BC, May 14, 2025 /PRNewswire/ - Integra Resources Corp. ("Integra" or the "Company") (TSXV: ITR) (NYSE American: ITRG) is pleased to announce financial and operating results for the three months ended March 31, 2025 (the "first quarter" or "Q1 2025"). The Company will host a conference call to discuss first quarter 2025 results on Thursday, May 15, 2025 at 11:00 AM Eastern Time / 8:00 AM Pacific Time.

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

First Quarter 2025 Highlights:

• Q1 2025 represented a milestone for Integra as its first full quarter as a gold producing company.
• Gold production from the Florida Canyon Mine ("Florida Canyon") was 19,323 ounces and gold sold was 19,540 ounces, at an average realized gold price of $2,888 per ounce.
• Cash costs and mine-site all-in sustaining costs ("AISC")¹ for the first quarter were $2,016 and $2,342 per ounce of gold sold, respectively; total AISC for the Company during the first quarter was $2,446 per ounce of gold sold.
• Adjusted earnings¹ for the first quarter was $4.4 million, or $0.03 per share.
• Cash flow from operating activities during the first quarter was $16.1 million; cash flow from operating activities before changes in non-cash working capital was $12.3 million.
• Expenditures at the DeLamar Project ("DeLamar"), Nevada North Project ("Nevada North"), and other exploration properties totaled $2.3 million during the quarter.
• Strengthened financial position as at March 31, 2025, with a cash balance of $61.1 million and working capital¹ of $63.8 million.
• Appointment of several key executives including Clifford Lafleur to the position of Chief Operating Officer, Dale Kerner to the position of Vice President, Permitting, and Sean Deissner to the position of Vice President, Finance.
• Formal submission of the updated and refined Mine Plan of Operations ("MPO") to the U.S. Bureau of Land Management ("BLM") for DeLamar.

George Salamis, President, CEO and Director of Integra commented: "We are pleased to report strong gold production and positive financial results from Florida Canyon for the first quarter of 2025. The mine continues to demonstrate its ability to generate cash flow to support Integra's growth strategy, which was the basis for its acquisition in late 2024. Solid performance from Florida Canyon this quarter resulted in an increased cash balance to $61.1 million at the end of the quarter, marking the Company's strongest financial position ever. Integra's growing cash balance ideally positions the Company to complete important mine-site capital projects at Florida Canyon in Q2 and Q3 2025 relating to, among other things, heap leach pad expansions, pre-stripping campaigns, and mining fleet additions and enhancements. During the first quarter, Integra also announced several key executive appointments which enhance our operating capabilities and better position the Company for the next stage of growth coming from both Florida Canyon and our high-quality development projects in the Great Basin. The focus for the remainder of 2025 continues to be optimizing and demonstrating growth at Florida Canyon, significant permitting advancement and a feasibility study planned for DeLamar, and continued de-risking activities and advanced study work at Nevada North."

Financial and Operating Highlights

Unit abbreviations in tables: kt = thousand tonnes, g/t = grams per tonne, Au = gold, oz = troy ounce, $000s = thousands of U.S. dollars, $/sh = U.S. dollars per share, $/oz = U.S. dollars per gold ounce, $/oz sold = U.S. dollars per gold ounce sold.

First Quarter 2025 Financial and Operating Summary

At Florida Canyon, total crushed and run-of-mine ("ROM") gold mineralized material delivered to the pad for the first quarter was 3.0 million tonnes with a strip ratio of 0.60. The average grade of gold ore processed during the period was 0.23 grams per tonne ("g/t") gold. Mining and ore placement rates for the quarter were slightly lower due to scheduled mobile fleet maintenance.

Florida Canyon produced 19,323 ounces of gold and sold 19,540 ounces of gold during the first quarter of 2025. Gold production exceeded expectations, partly due to the recovery and processing of approximately 2,000 ounces of previously unrecovered gold confined within an electrowinning tank as part of a one-time efficiency improvement project. Strong gold production was further supported by the continued ramp-up of solution flow rates through the heap leach pads and the new carbon-in-column circuit commissioned in late 2024.

Cash costs and mine-site AISC during the first quarter totaled $2,016 and $2,342 per ounce of gold sold, respectively.  Total AISC for the first quarter was $2,446 per ounce of gold sold. Increased costs during the quarter at Florida Canyon can be partially attributed to a ramp up of capital spending for pre-stripping activities, higher royalty payments due to the increased spot gold price, and increased tax-related production costs. Integra will provide further details on costs for the remainder of 2025 as part of formal guidance to be published prior to the release of second quarter 2025 results.

Several mine optimization studies continue to progress at Florida Canyon, some of which are expected to be completed in the first half of 2025, while others will continue throughout 2025. One of the optimization studies in-progress is the review of the mobile equipment fleet, which will require planned component replacements in 2025 and 2026. Other optimization studies are evaluating several components of the mining operation itself, including metallurgy and gold recovery, mine sequencing, and pit slope/geotechnical studies aimed at reducing future waste stripping campaigns.

2025 sustaining capital expenditures will include the projected $12 million expansion of the South Heap Leach Pad Phase III-b scheduled to begin in the second quarter of 2025 and to be completed in the third quarter of 2025. As previously noted, capital for the mobile equipment fleet upgrades and servicing will also be reflected in sustaining capital for the remaining quarters in 2025. Integra will provide further details on these capital expenditures as part of formal guidance to be published prior to the release of second quarter 2025 results.

In May 2025, Integra initiated a 10,000 meter reverse circulation drill program focused on near-mine gold exploration targets identified at Florida Canyon, designed to support oxide gold mineral reserve and resource growth and mine life extension. The drill program has a budget of $1.5 million and is expected to conclude in the third quarter of 2025, with initial results expected to be released during the summer months of 2025. The drill program will support a gold mineral resource and reserve update, and a revised life-of-mine plan expected in early 2026.

The DeLamar Project

Integra submitted an updated and refined MPO to the BLM for the DeLamar gold and silver project in late March 2025. The submission of the updated MPO to the BLM initiates the pathway for the issuance of a Notice of Intent ("NOI"), which is a formal announcement of BLM's intent to prepare an Environmental Impact Statement ("EIS") to evaluate the potential environmental effects of the proposed action in accordance with the National Environmental Policy Act ("NEPA"). The NOI is followed by a scoping process which includes engagement with federal, state, and local agencies and the public. Once scoping is completed, the BLM will conduct an environmental impact analysis for the proposed action as well as reasonable alternatives to the proposed action. Through this alternatives evaluation process, refinements to the MPO may be identified that reduce environmental impacts.  A Draft EIS ("DEIS") will publish the results of the BLM's environmental analysis and will be open to public comment for a minimum of 45 days. Public comments on the DEIS will be addressed by the BLM in the Final EIS ("FEIS") and accompanying Record of Decision ("ROD") document, which may include the BLM's proposed measures to mitigate potential environmental impacts. The BLM's environmental analysis under NEPA (NOI to FEIS) is anticipated to span two years, and represents a rigorous, transparent, and prescriptive permitting framework that guides the federal review of mining projects on public lands. Federal permitting will be complemented by a host of other permits from multiple Idaho state agencies that serve to protect the quality of Idaho's air, water, and land. Integra's recently updated and submitted MPO for DeLamar reflects a significantly optimized and environmentally enhanced mine plan, including a more compact project footprint and design modifications aimed at reducing projected carbon emissions and water usage. These improvements were developed through extensive technical analysis, stakeholder engagement, and a focus on the integration of modern sustainable mining practices.

During the first quarter, Integra also made substantial progress advancing the feasibility study for DeLamar. The Company expects to publish the results of a feasibility study in H2 2025. The feasibility study contemplates an open-pit gold and silver heap leaching operation on site.

The Nevada North Project

Nevada North consists of two mineral exploration deposits, the Wildcat Deposit ("Wildcat") and the Mountain View Deposit ("Mountain View"). During the first quarter, efforts at Nevada North were focused at Wildcat. The Final Environmental Assessment ("EA") and Finding of No Significant Impact for the Wildcat Exploration Plan of Operations was published by the BLM Humboldt River Field Office on April 17, 2025. The BLM's review of the EA determined that the Proposed Action Alternative will not significantly affect the quality of the human environment. Concurrence from the Nevada State Historic Preservation Office is required to finalize the BLM decision and is anticipated to be received in mid-2025. The Company anticipates completing a metallurgical test work program for Wildcat in H2 2025 and commencing a geochemical sampling program designed to assess future development criteria for mineralized material and waste rock, in Q2 2025. Metallurgical and geochemical testing is being completed to support future economic studies and permitting efforts at Nevada North. These initiatives support Integra's long term growth strategy which involves the de-risking and permitting of its key development stage heap leach projects.

A Mountain View Exploration Plan of Operations and Nevada Reclamation Permit Application were submitted to the BLM Black Rock Field Office and Nevada Division of Environmental Protection on May 9, 2025. These submittals initiate the environmental review and permitting process for future advanced exploration activities at Mountain View.

With greater financial resources currently available, Integra is focused on accelerating various technical studies to de-risk Nevada North and advance the asset through permitting.

Executive Appointments

During the first quarter Integra appointed several new executives to better position the Company to execute its operational and growth focused strategy:

• On February 20, 2025, Dale Kerner was appointed to the position of Vice President, Permitting. Mr. Kerner brings more than 25 years of experience in environmental permitting and regulatory compliance, with a deep understanding of the permitting landscape in the U.S. Mr. Kerner joins Integra from Perpetua Resources Corp., where he was instrumental in successfully permitting the Stibnite Gold Project in Idaho – one of the more complex permitting processes in the U.S., which recently received a final Record of Decision from the U.S. Forest Service.
• On March 25, 2025, the Company announced the appointment of Clifford Lafleur to the position of Chief Operating Officer. Mr. Lafleur has more than 25 years of experience spanning mine development, operations, and mine optimization. Most recently, Mr. Lafleur played a key role in the growth and success at SilverCrest Metals Inc., ultimately leading to the company's $1.7 billion sale to Coeur Mining Inc. in 2025.
• On March 28, 2025, Sean Deissner was appointed to the position of Vice President, Finance. Mr. Deissner is a Chartered Professional Accountant with over 15 years of experience in the mining industry, specializing in financial reporting, corporate finance, and strategic leadership. Mr. Deissner served as a key member of the executive team at SilverCrest Metals Inc., where he led the transformation of the financial reporting function, and directed the company's tax strategy and compliance initiatives, contributing to its successful acquisition for $1.7 billion by Coeur Mining Inc. in 2025.
