The MRE incorporates the results from the highly successful stockpile drill program completed in
DeLamar Technical Report Highlights:
- Including the 2023 DeLamar MRE, Integra now controls a total M&I resource of 6.2 million ounces (“Moz”) AuEq and a total Inferred resource of 0.9Moz AuEq across its key projects located in
Idaho andNevada , representing one of the largest resource endowments in theGreat Basin of theUSA not controlled by a major mining company2. - Stockpile & Backfill Resource Update:
- The maiden stockpile resource estimate contains an Indicated resource of 504 thousand ounces (“koz”) AuEq at 0.37 grams per tonne (“g/t”) AuEq, including 296koz gold (“Au”) and 16.1Moz silver (“Ag”) and an Inferred resource of 46koz AuEq at 0.30 g/t AuEq, including 26koz Au and 1.5Moz Ag.
- The Company allocated a total of
~US$4.6 million to the stockpile drill program which successfully resulted in the addition of >500kozs AuEq (M&I), representing the lowest discovery cost per ounce in the history of DeLamar.
- The Company allocated a total of
- A portion of the mineralized stockpile and backfill material was moved as a pre-stripping cost in the 2022 Pre-feasibility Study (“PFS”), however this material is expected to be processed in future economic studies. The stockpile and backfill material is also expected to reduce the overall mining cost as the material is located at surface and was previously mined, reducing or eliminating additional blasting costs.
- The maiden stockpile resource estimate contains an Indicated resource of 504 thousand ounces (“koz”) AuEq at 0.37 grams per tonne (“g/t”) AuEq, including 296koz gold (“Au”) and 16.1Moz silver (“Ag”) and an Inferred resource of 46koz AuEq at 0.30 g/t AuEq, including 26koz Au and 1.5Moz Ag.
- Total DeLamar and Florida Mountain Resource Update:
- The total DeLamar M&I resource contains 4.8Moz AuEq at 0.60 g/t AuEq, including 2.9Moz Au and 142.7Moz Ag.
- The total DeLamar Inferred resource contains 621koz AuEq at 0.45 g/t AuEq, including 428koz Au and 15.0Moz Ag.
- Oxide-mixed Heap Leach Resource Update:
- The oxide and mixed heap leach portion of the M&I resource contains 2.6Moz AuEq at 0.50 g/t AuEq, including 1.6Moz Au and 73.9Moz Ag.
- The oxide and mixed heap leach portion of the Inferred resource contains 284koz AuEq at 0.36 g/t AuEq, including 199koz Au and 6.6Moz ounces Ag.
- The significantly increased oxide and mixed resource at DeLamar demonstrates the potential for an extended heap leach mine life in future phases of operations.
- The Company anticipates filing the Mine Plan of Operations (“MPO”) for DeLamar in Q4 2023, making DeLamar one of the only precious metal development projects in the
Western United States that is actively being advanced towards a production permit.

Michael Gustin , MDA a division of RESPEC ofReno, Nevada , is a Qualified Person as defined in NI 43-101, is responsible for reporting Mineral Resources for DeLamar.Mr. Gustin is independent of the Company.- In-Situ Oxide and Mixed and Stockpile Mineral Resources are reported at a 0.17 and 0.1 g/t AuEq cut-off, respectively, in consideration of potential open-pit mining and heap-leach processing.
- Non-Oxide Mineral Resources are reported at a 0.3 g/t AuEq cut-off at DeLamar and 0.2 g/t AuEq at Florida Mountain in consideration of potential open pit mining and grinding, flotation, ultra-fine regrind of concentrates, and either Albion or agitated cyanide-leaching of the reground concentrates.
The Mineral Resources are constrained by pit optimizations set out in the Technical Report.- Gold equivalent grades were calculated using the metal prices and recoveries presented in the Technical Report.

Forward-looking statements are based on a number of factors and assumptions made by management and considered reasonable at the time such information is provided. Assumptions and factors include: the Company’s ability to complete its planned exploration programs; the absence of adverse conditions at mineral properties; no unforeseen operational delays; no material delays in obtaining necessary permits; the price of gold remaining at levels that render mineral properties economic; the Company’s ability to continue raising necessary capital to finance operations; and the ability to realize on the mineral resource and reserve estimates. Forward‐looking statements necessarily involve known and unknown risks and uncertainties, which may cause actual performance and financial results in future periods to differ materially from any projections of future performance or result expressed or implied by such forward‐looking statements. These risks and uncertainties include, but are not limited to: integration risks; general business, economic and competitive uncertainties; the actual results of current and future exploration activities; conclusions of economic evaluations; meeting various expected cost estimates; benefits of certain technology usage; changes in project parameters and/or economic assessments as plans continue to be refined; future prices of metals; possible variations of mineral grade or recovery rates; the risk that actual costs may exceed estimated costs; geological, mining and exploration technical problems; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing; the speculative nature of mineral exploration and development (including the risks of obtaining necessary licenses, permits and approvals from government authorities); title to properties; and management’s ability to anticipate and manage the foregoing factors and risks. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in the forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended.
