Integra Resources Delivers Record Mining Rates & Strengthens Balance Sheet at Florida Canyon

• Florida Canyon mined 3.0 million tonnes of ore and 3.9 million tonnes of waste at a 1.30 strip ratio in First Quarter 2026, achieving a record 76,800 tonnes per day mining rate following the commissioning of six Caterpillar 785 haul trucks.
• The operation produced 12,635 ounces of gold, with approximately 3,000 ounces deferred due to reduced solution flow rates to a Phase II leach pad cell containing fine ore from the N2 pit, addressed through a blending strategy targeting nominal leach rates.
• The Company raised US$61 million in February 2026, increasing cash and cash equivalents to US$105.6 million as at 31 March 2026 to fund DeLamar pre-production expenditures and a strategic land acquisition near the project.
• First Quarter 2026 capital allocation totalled approximately US$33.5 million across sustaining and non-sustaining capital at Florida Canyon (US$12 million), DeLamar and Nevada North engineering and permitting (US$5 million), and DeLamar pre-production and de-risking activities (US$16.5 million).
• The Company maintains 2026 production guidance of 70,000 to 75,000 ounces of gold, with deferred First Quarter ounces targeting recovery over the remainder of 2026 as leach pad performance normalises and elevated mining rates continue.

Company Overview

Integra Resources Corp. (TSXV: ITR; NYSE American: ITRG) is a precious metals producer in the Great Basin of the Western United States operating the Florida Canyon Mine in Nevada. The Company is advancing two flagship development-stage heap leach projects: the past-producing DeLamar Project in southwestern Idaho and the Nevada North Project in western Nevada.

Florida Canyon Achieves Record Mining Performance Through Fleet Expansion

Integra Resources Corp. (TSXV: ITR; NYSE American: ITRG) reported operational results from the Florida Canyon Mine for the quarter ended March 31, 2026, marking a period of operational momentum characterised by record mining throughput and fleet capacity additions. The operation mined 3.0 million tonnes of ore and 3.9 million tonnes of waste at a strip ratio of 1.30, delivering a total mining rate of 76,800 tonnes per day, the highest rate achieved in the mine's operational history.

The mining rate increase was driven by the commissioning of six Caterpillar 785 haul trucks during First Quarter 2026. This addition completes a fleet expansion programme initiated in 2025, which added eight Caterpillar 785 haul trucks, one Caterpillar 992HL loader, and one Hitachi EX3600 front shovel to the operation. The expanded fleet is designed to manage the historical waste stripping inherited from prior operators while improving operational flexibility and production consistency in future periods.

Of the ore mined, 1,074,000 tonnes were placed directly onto leach pads, while 1,784,000 tonnes were crushed before placement, bringing the total ore to leach pads to 2,858,000 tonnes. The processed material reported an average grade of 0.19 grams per tonne gold with a recovery rate of 59.9%, yielding production of 12,635 ounces of gold and 11,622 ounces of silver during the quarter. The mine sold 12,518 ounces of gold and 11,466 ounces of silver in the period.

Leach Pad Flow Rate Constraint Defers 3,000 Ounces Into Remainder of 2026

Production in First Quarter 2026 was affected by temporarily reduced solution flow rates to a specific Phase II leach pad cell. The cell contains fine ore from the newly opened N2 pit, a material characteristic that required operational adjustment. The Company developed a blending strategy targeting nominal leach rates for this fine material, a measure designed to normalise solution flow dynamics through the affected cell.

The reduced flow rates resulted in approximately 3,000 ounces of gold being deferred from First Quarter 2026 production. The Company expects these ounces to be recovered through ongoing leaching over the remainder of 2026 as the blending strategy is implemented and the Phase IIIB leach pad continues to ramp up. Based on this expectation, the Company maintained its full-year 2026 production guidance of 70,000 to 75,000 ounces of gold, with the majority of deferred First Quarter ounces targeting recovery through the remainder of the year.

President, Chief Executive Officer, and Director George Salamis stated: 

"The first quarter of 2026 marked a period of strong operational progress at Florida Canyon, with record mining rates and the successful ramp-up of our Phase IIIB leach pad. While gold production in the quarter reflects temporary constraints, the deferred ounces are expected to be recovered over the balance of the year. Importantly, with these gold ounces expected to be recovered over the balance of the year, we maintained our full-year production guidance, underscoring our confidence in the operation and the improvements we have made to the Mine."

The Company expects production to trend higher through the balance of 2026 as mining rates remain elevated and leach pad performance continues to normalise following the implementation of the blending strategy and ongoing Phase IIIB ramp-up.

US$61 Million Financing Strengthens Balance Sheet & Funds DeLamar Pre-Production Activities

Integra closed a US$61 million bought deal public offering in February 2026, significantly strengthening the Company's financial position. Cash and cash equivalents stood at US$105.6 million as at March 31 2026, an increase driven by the equity raise and positive operating earnings from Florida Canyon during the quarter.

Proceeds from the offering are being used to fund pre-production expenditures at the DeLamar Project and funded the acquisition of a strategic land position near the DeLamar Project in February 2026. The strengthened cash position provides the Company with financial flexibility to continue optimising Florida Canyon operations while advancing DeLamar without compromising balance sheet discipline, according to the Company.

First Quarter Capital Allocation Targets Florida Canyon Optimisation & DeLamar De-Risking

First Quarter 2026 represented a capital-intensive period across Integra's asset portfolio, with expenditures directed toward sustaining Florida Canyon operations and de-risking the DeLamar Project. The Company allocated approximately US$12 million to sustaining and non-sustaining capital at Florida Canyon, including capitalised waste stripping and initial cash payments on new mining equipment.

Approximately US$5 million was allocated toward project expenses at DeLamar and Nevada North, covering engineering and permitting work. DeLamar pre-production and de-risking activities received approximately US$16.5 million, comprising a US$3.4 million initial deposit to Idaho Power and US$12.5 million spent to acquire the strategic land position near the DeLamar Project.

Salamis stated: 

"In parallel, we significantly strengthened our balance sheet through a $61 million financing and continued to invest in both sustaining capital at Florida Canyon and the advancement of DeLamar. We believe these investments position Integra for a stronger second half of 2026 and reinforce our strategy of building a sustainable, multi-asset gold producer."
