Integra Provides Overview of Upcoming Drill Program at Wildcat Deposit in Nevada

Vancouver, British Columbia – Integra Resources Corp. (“Integra” or the “Company”) (TSXV: ITR; NYSE American: ITRG) is pleased to provide an overview of the upcoming exploration drill campaign at the Wildcat Deposit (“Wildcat”), which combined with the Mountain View Deposit form the Nevada North Project (the “Project”). Wildcat is located within the Farrell mining district in northwest Nevada, 56 kilometers (“km”) (~35 miles) north of the town of Lovelock, in Pershing County. The 17,612-acre land package consists of 916 unpatented claims and 4 patented claims. Mineralization at Wildcat consists of a gold-dominated, low sulphidation, epithermal vein system with disseminated oxide, transition, and non-oxide mineralization hosted in permeable volcanic and intrusive rocks.

The Company intends to complete a ~2,000 meter (“m”) Phase 1 exploration drill program at Wildcat, commencing in June 2024. The drill program is designed to test the oxide mineralization adjacent to the existing mineral resource at Wildcat, while also testing the high-grade breccia target which is believed to be the feeder source of gold mineralization at Wildcat. The planned drill program is the first time Integra’s team will complete a significant follow up exploration program since the Company acquired the Project as part of the merger with Millennial Precious Metals Corp. (“Millennial”) in 2023. The Company believes that Phase 1 drilling has the potential to significantly increase the existing mineral resource at Wildcat by testing high-priority targets that could not be drilled previously due to permit restrictions.


  • Wildcat currently hosts a mineral resource of 746,297 ounces (“oz”) of gold (“Au”) and 6,437,869 oz of silver (“Ag”) or 829,152 oz of gold equivalent (“AuEq”) in the Measured and Indicated Category (“M&I”) (59,872,806 tonnes at 0.39 g/t Au and 3.34 g/t Ag) and 209,662 oz Au and 1,980,129 oz Ag or 235,146 oz AuEq in the Inferred Category (“Inf.”) (22,455,848 tonnes at 0.29 g/t Au and 2.74 g/t Ag).
    • The 2023 Nevada North Preliminary Economic Assessment (“PEA”) demonstrated strong project economics including an after-tax Net Present Value (“NPV”)5% of US$310 million (C$409 million1) and a 37% after-tax Internal Rate of Return (“IRR”) using base case metal prices of US$1,700/oz Au and US$21.50/oz Ag.2
    • Using recent metal prices of US$2,000/oz Au and US$23.00/oz Ag, the Nevada North Project delivers an after-tax NPV5% of US$490 million (C$647 million) and a ~54% after-tax IRR.2
  • Previous drilling at Wildcat completed by Millennial focused primarily on the Main Hill target which hosts the existing mineral resource. The upcoming drill campaign will test multiple underexplored targets outside the Main Hill area at Wildcat, which have demonstrated the potential to host additional mineralized material at Wildcat.
  • The 2,000 m Phase 1 exploration drill program will focus on achieving three main objectives:
    • Oxide resource expansion: The 2022 exploration program at Wildcat completed by Millennial increased the mineralized footprint from ~1.5 km by 1.5 km to ~3.0 km by 2.0 km through the collection of ~850 rock samples. Of these samples, ~99% were collected outside the proposed PEA pit and ~200 were above cut-off grade2. Three priority areas were identified within the expanded mineralized footprint, including the Crossroads, Breccia Pipe, and Rhyolitic Ridge targets. The 2024 drill program will be the first time the expanded mineralized footprint will be drill tested by the Company with the goal of increasing the oxide mineral resource in future studies. See Figure 1 for target locations and overview of 2022 grab sample program.
    • Testing high-grade Breccia Pipe target at depth: Significant geophysical, magnetic, and chargeability anomalies were interpreted below post-mineralization basalts 800 m north from the Main Hill resource. These anomalies are interpreted to be the potential location of high-grade epithermal feeder veins which will be drilled as part of the Phase 1 program. A discovery at the Breccia Pipe Target has the potential to materially augment both the size of the mineral resource and potential future economics at Wildcat. See Figure 2 for Wildcat schematic long sections with geophysics.
    • Metallurgical and geotechnical testing: Strategic drilling will be executed within the proposed PEA pit to collect additional material for future economic studies. Column leach tests completed for the 2023 PEA demonstrated excellent leachability of the tuff material (~75% of the in-pit mineralized material) with oxide recoveries up to ~80%. Test work planned in 2024 will seek to further optimize and improve the variability, size sensitivity, and kinetics observed within the tuff material. Further testing will also help the team better understand recoveries in the granodiorite (~25% of the in-pit mineralized material) which had recoveries of 52% in the 2023 PEA.2
  • Integra has observed a strong correlation at Wildcat between the presence of historical mines and the location of mineralization. Of the ~25 historical mines and adits located on the property, only 8 are located within the proposed PEA pits, suggesting a strong potential for new areas of mineralization at the targets designated for drilling in 2024.

Jason Kosec, President, CEO and Director of Integra commented: “We are extremely excited to kick off the much-anticipated 2024 drill program at Wildcat. The planned program is the first significant exploration drilling program at Wildcat since the deposit was explored by Millennial in 2022, when five new mineralized targets were discovered outside the 2023 PEA pit. We believe this drill program has the potential to significantly increase the near surface oxide mineral resource which will enhance future economics at Wildcat. Moreover, the discovery of the main feeder zone could be a potential game changer for Wildcat, altering the scope of what we currently know about the potential size of the deposit.”

Overview of Previous Millennial Exploration at Wildcat

In 2022, Millennial completed both drilling and a detailed mapping and sampling program at Wildcat. The sampling program included detailed surface mapping, a robust rock chip sampling program (~850 samples, ~23% of samples returned grades above 0.1 g/t Au), and detailed compilation of historic data. The mapping program successfully increased the mineralized footprint at Wildcat from ~1.5 km by 1.5 km to ~3.0 km by 2.0 km. Infill and metallurgical drilling which took place at Wildcat in 2022 was highly successful, demonstrating strong grade continuity, minimal overburden coverage, and excellent rock mechanics allowing for favourable pit wall angles and the potential to reduce stripping volumes and lower mining costs. Wildcat demonstrates an extremely low-strip ratio of 0.28 Life-of-Mine (“LoM”), which is presented in the 2023 PEA (Nevada North LoM strip ratio of 1.21). See Figure 3 for a cross section providing an overview of the mineralization at Wildcat.

Highlights from the 2022 drill program include (refer to Millennial news release date November 29, 2022):

  • WCCD-0003: 1.26 g/t oxide Au over 39.2 m from surface, including a high-grade intercept of 1.82 g/t oxide Au over 20.6 m
  • WCCD-0004: 0.93 g/t oxide Au over 41.4 m
  • WCCD-0005: 0.36 g/t oxide Au over 17.7 m and 0.55 g/t oxide Au over 68.6 m
  • WCCD-0006: 0.39 g/t oxide Au over 120.2 m from surface, including ~50 m of oxidized mineralization

2024 Exploration Drill Program at Wildcat

The 2024 exploration drill program at Wildcat will test the expanded mineralized footprint at Wildcat identified by Millennial in 2022. The drill program will focus on greenfield exploration targets that have the potential to expand the oxide mineral resource at Wildcat. Material will also be collected for metallurgical and geotechnical testing to be used in future studies.

The greenfield portion of the 2024 drilling program will focus on three primary targets:

  • Breccia Pipe Target: One of the main objectives for the 2024 program is to drill into the previously untested high-grade Breccia Pipe target. Located approximately 800 m north of the Main Hill resource, this target was identified through a combination of conceptual metallogeny and recompilation of geophysical information. Considering the abundance of rhyolite tuff in the area, a large volcanic diatreme, which is a strong indicator of highly permeable conduits for gold rich hydrothermal fluid, is not present at surface. The absence of a diatreme on surface suggests it may be located below the post-mineralization basalts to the north. Using pre-existing geophysical data, a new 3D model was developed that showed significant magnetic and chargeability anomalies immediately below the basalts. Magnetic and chargeability anomalies in this area indicate high sulphur content which is generally associated with magnetite, pyrrhotite, pyrite, or chalcopyrite and can be strongly correlated with gold bearing structures. The first three drill holes of the 2024 campaign are targeting these anomalies.
  • Crossroads Target: The Crossroads target is approximately ~1,300 m by 600 m in size and is characterized by disseminated mineralization within silicified tuff breccia. Of the ~36 samples collected at the Crossroads target in 2022, ~69% returned oxide grades >0.10 g/t Au with values up to 2.44 g/t Au, suggesting that oxide mineralization extends into this target. The Crossroads target geology is identical to Main Hill, however, most of the granodiorite located below the Crossroads target is not mineralized. This implies that the main feeder structure of the gold mineralization at the Crossroads target may be a fault located east of the PEA pit. This fault will be tested for high-grade potential at depth during the 2024 drill program.
  • Rhyolitic Ridge Target: The untested Rhyolitic Ridge target consists of multiple large gold geochemical soil and geophysical anomalies. Located approximately 300 m east of Main Hill and presenting similar lithologies to the mineral resource area, Rhyolitic Ridge contains significant soil anomalies with ~55% of the 116 samples tested returning grades above 0.1 g/t Au.

Wildcat Deposit Overview

Wildcat is located within the Farrell mining district in Nevada, 56 km north of the town of Lovelock within Pershing County. The property can be accessed year-round by roads from Lovelock via State Route 399 and Seven Troughs Road. The 17,612-acre land package consists of 916 unpatented claims and 4 patented claims. The claims are located on publicly-owned lands administered by the U.S. Bureau of Land Management.

Mineralization at Wildcat is genetically related to a mid-Miocene rhyolite dome complex developed during the extensional dominated tectonic environment of the Nevada Rift. The bulk-tonnage gold mineralization is hosted in tuff breccia that is considered to be the erosional remnant of a subaerial apron to a phreatomagmatic diatreme vent. The tuff breccia-hosted gold mineralization was fed from low-sulphidation veins in the underlying Mesozoic granodiorite basement. Additional bulk-tonnage gold mineralization associated with tuff breccia may be present elsewhere within the district, particularly beneath a post-mineral mafic volcanic cover sequence and within the interpreted main feeder diatreme. Low-sulphidation epithermal veins beneath the tuff breccia have the potential to host high-grade gold targets.
