Integra Resources Corp. (“Integra” or the “Company”) (TSX-V: ITR; NYSE American: ITRG) is pleased to announce additional drill results from the DeLamar Project (“DeLamar” or the “Project”) located in southwestern Idaho. The drill results announced today are from a metallurgical drill program at DeLamar as well as 24 additional drill holes from the 11,000 m stockpile drill program at the Project. The stockpile drill program, the results of which continue to exceed expectations, has the potential to extend the heap leach mine life and positively impact the already robust economics of the DeLamar Project.

“On the back of the successful release of the first 10 drill holes from the stockpile drill program in December 2022, the Company is pleased to announce the next 24 drill holes from this program that further demonstrate the immense value potential in the 60 million tonnes of gold-silver mineralized stockpile and backfill material left behind by previous mine operators. Today’s drill results are well within our expected grade range of 0.3 g/t AuEq to 0.6 g/t AuEq and have the potential to provide material to further expand the heap leach mine life at DeLamar. This material could enhance the strong economics of the Project presented in the 2022 Pre-feasibility Study while also creating significant value from the portion of backfill material that was proposed to be handled as a pre-stripping cost in that study,” stated George Salamis, President and CEO of Integra Resources. “The Company has increased the drill count on the Project to three drill rigs as we continue the successful execution of the stockpile drill program in anticipation of completing an updated resource estimate on this material in the first half of 2023. In addition to these drill results, considerable mineralization in the metallurgical drill holes released today further illustrate the strong gold-silver grades and significant widths at DeLamar. These metallurgical drill results are significant as they exceed the average grade of the existing deposit, demonstrating continued upside at the Project.”

(1) Downhole thickness: true width varies depending on drill hole dip; most drill holes are aimed at intersecting the vein structures close to perpendicular therefore true widths are close to downhole widths (approximately 70% conversion ratio).(2) Intervals reported are uncapped.(3) Gold equivalent = g Au/t + (g Ag/t ÷ 77.70). Rounding may cause minor discrepancies in the AuEq column.

Execution of Drill Program: Methodology and Timeline

The stockpile drill program will be executed at 60 m collar spacings with select 30 m infill test holes to further verify grade variability. All drilling will be vertical through the entirety of the stockpiles and backfill material. This drilling will be conducted by a combination of Sonic and traditional RC with casing advance drilling methods. Both these drilling methods will serve to maintain high sample quality and integrity throughout the drilling process. Additionally, the two drilling methods will provide a basis for comparison for continuity. Sampling will be conducted at 1.5 m intervals for the whole of the drilling program with all samples sent to a third-party lab for analysis. These drilling methods also provide the opportunity for more advanced metallurgical tests in the future.

Annual Grant of Equity Incentive Awards

The Company announces that it has granted a total of 479,760 options, 290,310 restricted share units and 247,500 deferred share units (together, the “Equity Incentive Awards”) to various investor relations employees, executives and directors of the Company. The Equity Incentive Awards have been granted pursuant to the Company’s Amended and Restated Equity Incentive Plan and are subject to vesting provisions. The options have an exercise price of C$0.87 per share and will expire five years from the date of grant.

Sampling and QA/QC Procedure

Thorough QA/QC protocols are followed on the Project, including insertion of duplicate, blank and standard samples in the assay stream for all drill holes. The samples are submitted directly to American Assay Labs in Reno, Nevada for preparation and analysis. Analysis of gold is performed using fire assay method with atomic absorption (AA) finish on a 1 assay ton aliquot. Gold results over 5 g/t are re-run using a gravimetric finish. Silver analysis is performed using ICP for results up to 100 g/t on a 5-acid digestion, with a fire assay, gravimetric finish for results over 100 g/t silver.
