VANCOUVER, BC , April 14, 2026 /CNW/ - Integra Resources Corp. ("Integra" or the "Company") (TSXV: ITR) (NYSE American: ITRG) is pleased to announce additional results from the growth drilling program at the Company's primary operating asset, the Florida Canyon Mine ("Florida Canyon") located in Nevada. The results continue to demonstrate broad intervals of near-surface oxide gold mineralization from both historical dump material and near-mine in-situ targets, highlighting the potential to expand mineral resources, support future mine planning, and enhance near-term production.

During the 2025 growth drilling program 16,009 meters ("m") of reverse circulation ("RC"), sonic and core drilling were completed. The recently announced 2026 drilling program consists of 42,500 m of RC and core drilling with 33,500 focused on resource development at the Florida Canyon Mine and 9,000 m focused on testing new gold targets identified around the Florida Canyon and Standard Mine areas.

Highlights:

• Opportunity 1: Near-surface oxide potential from historical dump material: Drilling targeting large volumes of historical, gold-mineralized, low-grade waste material that was below the mining cut-off in a significantly lower gold-price environment. These areas demonstrate a significant near-term opportunity to increase mineral resources and potentially extend mine life at Florida Canyon.
  • Broad oxide gold intercepts from historical South Mine Dump ("South Dump") material, including:
    • FCM25-0655: 0.30 grams per tonne ("g/t") gold ("Au") over 102.1 m
    • FCMR25-0896: 0.22 g/t Au over 103.6 m
    • FCMR26-0908: 0.26 g/t Au over 91.4 m       
    • FCMR26-0954: 0.55 g/t Au over 54.9 m
    • FCMR25-0893: 0.23 g/t Au over 91.4 m       
    • ~67% of drill intercepts exceed the current mine cut-off grade of 0.11 g/t Au

• Opportunity 2: Expand in-situ resources between existing mine open pits: Drilling targeting "saddle" and "ridge" ("Inter-Pit") areas located between active and historical pits. Many of these areas have been sparsely drilled historically and offer meaningful growth potential directly adjacent to current and future mining phases.
  • Significant thickness from near-mine in-situ drilling at the Radio Tower Pit, including:
    • 2025-Met-R02: 0.32 g/t Au over 138.1 m
    • 2025-GT-R03: 0.42 g/t Au over 58.5 m
    • 2025-GT-R05: 0.53 g/t Au over 44.3 m
    • ~26% of drill intercepts within the Radio Tower Pit exceed the current Radio Tower cut-off grade of 0.14 g/t Au
  • Additional thick intercepts from the C7 / Central Pit area highlighting strong vertical continuity, including:
    • FCM25-0617: 0.36 g/t Au over 128.0 m
    • 2025-GT-C01: 0.82 g/t Au over 50.0 m
    • 2025-GT-C04: 0.48 g/t Au over 97.5 m
    • ~38% of drill intercepts within the C7 / Central Pit area exceed the current cut-off grade of 0.11 g/t Au

Key Observations:

• Mineralization defined in close proximity to existing pits and infrastructure has the potential to enhance economic value.
• Results continue to support a growing inventory of near-surface mineralization expected to contribute to future resource and reserve growth and to extend mine life.
• Strong continuity across multiple intercepts exceeding 40 m at >0.2 g/t Au, reinforcing potential for pit expansion and near-term mine planning.
• Strong grade continuity across wide intervals.
• Strong alignment with heap leach processing characteristics.

George Salamis, President, CEO and Director of Integra commented: "Integra continues to focus on incremental resource growth and the potential to add gold ounces where they matter most, within haulage distance of the Florida Canyon Mine and its processing infrastructure. These latest drill results continue to reinforce our view that Florida Canyon hosts significant, scalable near-surface oxide gold mineralization with the potential to support long-term growth. Not all gold ounces are created equal, and gold ounces identified within and adjacent to our existing operations carry significantly higher value given their proximity to infrastructure and ability to be incorporated into the mine plan with minimal capital.

What stands out most in these latest results is the consistency and thickness of gold mineralization across multiple areas of the mine, both within historical dumps and in near-mine in-situ zones. This combination provides Integra with an opportunity to expand mineral resources in a capital-efficient manner while enhancing operational flexibility.

We are seeing a clear trend of growing near-surface mineralization that has the potential to translate into a larger resource base and an extended mine life in our upcoming technical report expected to be completed in the third quarter of 2026. In the current gold price environment, advancing these low-strip, near-surface opportunities represents a compelling pathway to deliver sustained production growth and long-term value for our shareholders."

Drilling Overview

The growth drilling program at Florida Canyon is focused on delineating near-surface oxide gold mineralization within and adjacent to existing mining areas. The program is designed to support future mineral resource and reserve updates and inform life-of-mine planning.

Opportunity 1 Drilling Overview: Near-Surface Oxide Gold Potential from Historical Dump Material

Within the permitted Florida Canyon Mine boundary, several volumes of historically mined, low-grade gold-mineralized dump material remain in surface dumps. These materials were mined during periods of significantly lower gold prices and at higher cut-off grades than those currently applied at the Florida Canyon Mine.

Drilling results continue to confirm that these historical waste dumps host broad, continuous intervals of oxide gold mineralization, including intercepts exceeding 80 m in thickness, as well as numerous intervals in the 50 to 70 m range at grades above 0.20 g/t Au.

Top intercepts from drilling at the South Dump include:

• FCM25-0655: 0.30 g/t Au over 102.1 m
• FCMR25-0896: 0.22 g/t Au over 103.6 m
• FCMR26-0908: 0.26 g/t Au over 91.4 m       
• FCMR26-0954: 0.55 g/t Au over 54.9 m
• FCMR25-0893: 0.23 g/t Au over 91.4 m       
• FCM25-0658: 0.25 g/t Au over 88.4 m
• FCMR26-0912: 0.28 g/t Au over 86.9 m

• ~67% of drill intercepts exceed the current mine cut-off grade of 0.11 g/t Au assuming a gold price of US$2,000 per ounce among several other factors.

These materials are located within or immediately adjacent to existing mining infrastructure, significantly reducing haulage distances and capital requirements, and enhancing their economic value relative to more distal gold mineralization.

Key observations

• Consistent gold grade distribution across large volumes of previously mined but unprocessed gold mineralized material.
• Mineralization remains near-surface, readily accessible and situated close to current processing infrastructure (~1km from South Dump, ~3km from North Dump).
• Material is expected to be amenable to heap leach processing, subject to ongoing metallurgical testing.
• Opportunity to convert previously uneconomic material into mineable inventory to enhance future mine life.

These historical dump zones represent a low-strip, capital-efficient opportunity to increase mineral resources and potentially provide supplemental ore feed for Florida Canyon operations. The Company expects these areas to be evaluated for inclusion in future mineral resource estimates and life-of-mine plans.

Opportunity 2 Drilling Overview: Expanding In-Situ Resources in the Inter-pit Areas, Between Existing Mine Open Pits

Drilling focused on gold resource expansion opportunities within "saddle" and "ridge" zones, located between existing open pits. Several of the Inter-Pit areas remain sparsely drilled and offer significant upside gold potential. Drilling of the Inter-Pit areas, including the C7 / Central Pit, North Pit and Radio Tower areas, continues to return broad and consistent zones of oxide gold mineralization, including multiple intercepts exceeding 100 m in thickness.

Notably, several of these intercepts exhibit grades above the current average resource grade at Florida Canyon Mine, suggesting the potential to not only increase total ounces but also improve the overall grade profile of the operation.

Top intercepts from in-situ drilling in the inter-pit areas include:

• 2025-Met-R02: 0.32 g/t Au over 138.1 m (Radio Tower Pit)
• FCM25-0617: 0.36 g/t Au over 128.0 m (C7 / Central Pit)
• 2025-GT-R03: 0.42 g/t Au over 58.5 m (Radio Tower Pit)
• 2025-GT-R05: 0.53 g/t Au over 44.3 m (Radio Tower Pit)
• 2025-GT-C01: 0.82 g/t Au over 50.0 m (C7 / Central Pit)
• 2025-GT-C04: 0.48 g/t Au over 97.5 m (C7 / Central Pit)
• FCM25-0687: 0.69 g/t Au over 36.6 m (North Pit)

• ~26% of drill intercepts within the Radio Tower Pit exceed the current Radio Tower cut-off grade of 0.14 g/t Au assuming a gold price of US$2,000 per ounce among several other factors.
• ~38% of the drill intercepts within C7 / Central Pit area exceed the current mine cut-off grade of 0.11 g/t Au assuming a gold price of US$2,000 per ounce among several other factors.

These areas are located within and adjacent to existing mining infrastructure and represent high-priority targets for resource growth and potential mine plan expansion.

Key observations

• Significant vertical continuity demonstrated by thick intercepts exceeding 100 m.
• Additional >50 m intercepts at Radio Tower, reinforcing consistency across the zone.
• Strong thickness-grade relationships supporting potential economic extraction.
• Mineralization occurs at shallow depths, consistent with low-strip mining scenarios.
• Zones remain open laterally, indicating further expansion potential.

The C7 / Central Pit and Radio Tower zones are expected to play an important role in future mineral resource and reserve updates, with strong potential to be incorporated into future pit designs and life-of-mine planning scenarios.

Sampling and QA/QC Procedure

Reverse circulation samples were collected at 5-foot intervals directly at the drill rig using pre-labeled bags. Samples were submitted to American Assay Laboratories ("AAL") in Reno, Nevada, an ISO/IEC 17025 accredited laboratory. AAL is independent of Integra. Sample preparation involved drying, jaw crushing to >70% passing 2 mm (10 mesh) and pulverizing a 300 g split to >85% passing 75 microns.

Gold analysis was performed on a 30-gram pulp using fire assay with ICP-AES finish. Samples returning >10 ppm Au were re-assayed using a gravimetric finish. Additionally, samples with Au >0.156 ppm underwent cyanide-soluble (0.3% NaCN/0.3%NaOH using a sample to solution ratio of 1:2 or 10g/20mL) analysis and preg-robbing (0.3% NaCN/0.3%NaOH + 1.71ppm/mL Au spike using 1:2 ratio calculates to 3.42ppm in the 10g/20mL) tests to assess metallurgical characteristics. Quality control protocols included the routine insertion of blank samples, certified reference materials (standards), and field and pulp duplicates. Blank material and standards were purchased from Moment Exploration Geochemistry. AAL also inserted internal control samples and duplicates within each batch.
