Integra Resources Launches Record 50,000-Metre Drill Program Targeting Resource Growth, Mine Life Extension & Advanced Engineering

• Integra Resources has launched a 50,000-metre drill program across Nevada and Idaho, the largest gold-focused exploration campaign in the Company's history.
• 42,500 metres of RC and core drilling is allocated to Florida Canyon, split between 9,000 metres targeting new gold targets around the Florida Canyon and Standard Mine areas, and 33,500 metres focused on resource development.
• 5,500 metres of resource conversion drilling is planned at the Nevada North Project's Wildcat Deposit, subject to EPO approval expected in the Second Quarter of 2026, while 2,500 metres of advanced engineering drilling at DeLamar will collect data ahead of future construction.
• Drilling at Florida Canyon has already commenced, with initial results anticipated in summer 2026 and an updated feasibility study and NI 43-101 technical report expected in the Third Quarter of 2026.
• The 2026 Drilling Program is the next phase in Integra's multi-year strategy to unlock additional value across its Great Basin gold-silver portfolio.

A Three-Asset Campaign

Integra Resources Corp. (TSXV: ITR | NYSE American: ITRG) has announced the launch of a 50,000-metre drill program across its Nevada and Idaho portfolio, the largest gold-focused exploration campaign in the Company’s history. The 2026 Drilling Program spans three assets: the producing Florida Canyon Mine in Nevada, the Nevada North Project’s Wildcat Deposit in Nevada, and the DeLamar Gold-Silver Project in southwestern Idaho.

The programme is structured around distinct objectives at each asset: near-mine and regional oxide gold exploration at Florida Canyon, resource conversion and development drilling to support an upcoming PFS at Nevada North, and collection of advanced engineering data in preparation for future mine development at DeLamar.

Programme Overview

The 2026 Drilling Program is described as the next phase in Integra’s multi-year strategy aimed at unlocking additional value across its portfolio of gold-silver assets in the Great Basin. The campaign is an important investment in Integra’s evolution as both a gold producer and an exploration-driven growth company, with drilling designed to expand mineral resources, extend mine life, and collect key engineering, metallurgical, and hydrogeological data to support future mine development.

President, CEO and Director George Salamis commented:

“The launch of our 2026 Drilling Program marks an exciting moment for Integra and its shareholders as we return to the drill bit in a meaningful way, to focus on resource growth and potential discoveries. This is high-return, infrastructure-led drilling. Much of the drilling will be focused on targets located near existing mining infrastructure, where success can be rapidly converted into production. With Florida Canyon now generating strong cash flow, we are reinvesting into high-impact drilling across our portfolio.”

Florida Canyon Mine: The Core of the Programme

The Florida Canyon Mine in Nevada accounts for approximately 42,500 metres of reverse circulation (RC) and core drilling, representing the majority of the total 2026 programme. The metreage is divided into two categories.

The first category covers approximately 9,000 metres of exploration drilling focused on testing new gold targets identified around the Florida Canyon and Standard Mine areas, collectively referred to as the Florida Canyon Property. This component targets oxide gold opportunities surrounding the existing mine’s infrastructure.

The second category covers approximately 33,500 metres, focused on resource development at the Florida Canyon Mine Property. This component also includes targeting and defining low-grade stockpiled rock.

Drilling at Florida Canyon has already commenced and is expected to continue through the Fourth Quarter of 2026. Initial results are anticipated during the summer of 2026. Portions of the programme will also support the updated Florida Canyon feasibility study and NI 43-101 technical report, which is expected to be completed in the Third Quarter of 2026.

Nevada North Project: Resource Conversion to Support Pre-Feasibility

The Nevada North Project component of the 2026 programme allocates 5,500 metres to the Wildcat Deposit. The programme is designed to support a future PFS and advance resource growth.

The Nevada North work is subdivided into approximately 500 metres of core drilling for metallurgical, geotechnical, and geochemical testing, and approximately 5,000 metres of resource conversion drilling to support the PFS. The programme also includes additional exploration drilling targeting extensions of known gold mineralisation.

Commencement of drilling at the Wildcat Deposit is conditional upon approval of the Exploration Plan of Operations by state and federal regulators. The Company anticipates receiving that approval in the Second Quarter of 2026, with drilling scheduled to commence in late Second Quarter of 2026 and to be completed by the Fourth Quarter of 2026.

DeLamar Gold-Silver Project: Advanced Engineering Data Collection

The DeLamar Gold-Silver Project in Idaho receives approximately 2,500 metres under the 2026 programme. This drilling is dedicated to collecting metallurgical, geotechnical, and hydrogeological data required for detailed engineering of the DeLamar Project in preparation for construction, once all applicable federal, state, and local permits are obtained.

The company describes DeLamar as one of the largest and most advanced undeveloped heap leach gold-silver projects in the Great Basin. The engineering-focused character of this work reflects the project’s development-stage maturity, with the 2,500 metres directed at closing data gaps needed for construction-readiness planning rather than expanding the in-situ resource.

Next Steps & Upcoming Milestones

Several near-term milestones follow from the 2026 Drilling Program. The Company expects EPO approval for the Wildcat Deposit at Nevada North from state and federal regulators in the Second Quarter of 2026, at which point drilling at Wildcat is scheduled to commence. Initial results from the Florida Canyon exploration and resource development programme are anticipated during summer 2026, with both the Florida Canyon and Nevada North drilling programmes expected to reach completion by the Fourth Quarter of 2026. The updated Florida Canyon feasibility study and NI 43-101 technical report, incorporating results from the drilling programme, is targeted for completion in the Third Quarter of 2026.
