• Drill results from Florida Mountain include:
  • FME-21-138 – 0.59 grams per tonne gold and 15.01 g/t silver (0.79 g/t gold equivalent) over 108.81 meters
    • Including 3.16 g/t Au and 131.00 g/t Ag (4.85 g/t AuEq) over 1.52 m
  • FME-21-141 – 0.50 g/t Au and 41.50 g/t Ag (1.03 g/t AuEq) over 73.15 m
    • Including 6.42 g/t Au and 745.00 g/t Ag (16.01 g/t AuEq) over 1.53 m
    • Including 2.04 g/t Au and 539.00 g/t Ag (8.98 g/t AuEq) over 1.52 m
  • FME-21-152 – 0.50 g/t Au and 31.63 g/t Ag (0.91 g/t AuEq) over 43.89 m
• Approximately the first 100 m of the Florida Mountain deposit host oxide and transitional gold-silver mineralization that could be amenable to heap leaching. The drill results announced today continue to demonstrate the strong continuity and grade of the oxide and transitional material destined for the heap leach pad as demonstrated in the Company’s 2022 Pre-feasibility Study.
• Drill results from BlackSheep include:
  • IGE-21-004 – 0.52 g/t Au and 110.58 g/t Ag (1.94 g/t AuEq) over 6.86 m
  • LDE-21-005 – 0.59 g/t Au and 11.23 g/t Ag (0.73 g/t AuEq) over 48.77 m
    • Including 8.62 g/t Au and 17.57 g/t Ag (8.85 g/t AuEq) over 1.52 m
• The BlackSheep target is a highly prospective, 25 square kilometer greenfield exploration target northwest of the DeLamar Deposit. Integra has done very limited exploration drilling in BlackSheep to date; however, the initial drill results suggest that BlackSheep could contain multiple oxide and transitional gold-silver targets that could further complement DeLamar.
• Generally, the first 40 m of material at BlackSheep is oxide and transitional and could be amenable heap leaching, subject to further metallurgical testwork. The Company also completed an extensive surface mapping and sampling program at BlackSheep, surface assay samples include:
  • Lucky Days – 2.76 g/t Au and 586.00 g/t Ag (10.30 g/t AuEq)
  • Georgianna – 13.33 g/t Au and 109.57 g/t Ag (14.74 g/t AuEq)
  • Twin Peaks – 6.12 g/t Au and 330.00 g/t Ag (10.37 g/t AuEq)
• With the exception of a portion of drill hole FME-21-138, none of the results released today were included in the recent 2022 Resource Estimate, further demonstrating upside potential for future gold and silver resource expansion at DeLamar.
• The Company is currently drilling the low-grade, gold-silver stockpiles at DeLamar left behind by previous operators.

Integra Resources Corp. (TSX-V: ITR) (NYSE American: ITRG) is pleased to announce drill results from the DeLamar Project located in southwestern Idaho. The drill results announced today further demonstrate the resource upside potential of the project in multiple areas, including the highly prospective BlackSheep target located on trend northwest of the DeLamar Deposit.

“Over the past 4 years of exploration work and economic studies, which include a Preliminary Economic Assessment and Pre-feasibility Study, one item has continued to demonstrate strong relevance at DeLamar, the vast, untapped and untested gold-silver upside potential of the Project. Multiple targets for resource expansion are located in proximity to and outside of the known gold-silver deposits at DeLamar and Florida Mountain,” states George Salamis, President and CEO. “In 4 short years, the Company has established a large gold-silver resource on the Project, as shown in the Company’s Pre-feasibility Study, while defining multiple targets on the Project with significant exploration potential. On average, the Company has discovered ounces on the Project at a cost of approximately US$10 per ounce.”

“As outlined in the Pre-feasibility Study, DeLamar has the potential to produce a significant amount of gold and silver with high-margins and low up-front capital. This profitable project will likely be further enhanced in the future through the exploration and drilling of multiple targets around DeLamar, as shown with these drill results. Even as the Company progresses the project into permitting and mine development, exploration and resource expansion will continue to be a key focus of the Company.”

The following table highlights selected intercepts from Florida Mountain drill results announced today:

(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)   Gold equivalent = g Au/t + (g Ag/t ÷ 77.70). Rounding may cause minor discrepancies in the AuEq column.
(3)   Intervals reported are uncapped

The intercepts reported today from Florida Mountain consist of mineralization with wide-spread low-grade gold-silver values, at times crosscut and underlain by narrower high-grade, steeply dipping low-sulphidation quartz-adularia veins. It is pertinent to note that with the exception of a portion of drill hole FME-21-138, none of the intercepts reported above were included in the 2022 DeLamar Resource Estimate completed alongside the PFS. It is also important to note that a large measure of some of the thicker intervals of mineralization reported today contain oxide and transitional gold-silver mineralization which, given their location, could be amenable to heap leaching.

The BlackSheep District, which includes the Lucky Days and Georgianna Targets, is host to extensive gold-silver-arsenic soil geochemical anomalies analogous to the size and scope of gold-silver-arsenic anomalies present at the multi-million-ounce DeLamar and Florida Mountain deposits that are adjacent to this area. At the more deeply eroded DeLamar and Florida Mountain deposits, the high-grade vein mineralization which was discovered and mined historically was partially in outcropping and surrounded by a halo of low-grade stockwork mineralization, which was subsequently mined by open pit. At the BlackSheep District, which is less deeply eroded, only the upper part of the stockwork vein halo is exposed, and the higher-grade veins are interpreted as being 100 m to 200 m below the current level of exposure. The drill results announced today targeted a very small fraction of these geochemically anomalous areas, with large tracts of land at both Georgianna and Lucky Days still to be drilled. In addition, multiple targets with large geochemical anomalies and mineralized surface showings within the BlackSheep District remain untested, including Twin Peaks, Statue Hills/Spain, Argentum and other highly gold-silver anomalous areas. This is a very large, 25 square kilometer area of untested potential.

In 2020, the Company undertook a preliminary regional mapping program of the BlackSheep area. Additional detailed mapping was then undertaken to characterize the mineralization at Lucky Days. In 2022, a further mapping program was undertaken by the exploration team focusing on Twin Peaks and Spain/Statue Hills to the North and an effort to map from Northern Lucky Days to Twin Peaks. Though complete assays of all samples have not been received, preliminary grab sample assays are encouraging, including surface samples ranging from 1.06 g/t Au to 6.12 g/t Au.

On-going Drill program:

The Company is currently engaged in a 11,000 m drill program designed to systematically test approximately 60 million tonnes of previously mined but not processed, oxidized and transitional gold-silver mineralisation that was stockpiled by previous mine operators. One drill rig is currently active on the project, with 9 drill holes completed in less than 2 weeks of drilling. It is expected that this drilling will take 3 to 4 months, with preliminary results scheduled to start arriving in the next 4 to 6 weeks. If successful, this program has the potential to add a vast amount of potentially heap leach gold-silver mineralization to future mine plans at a very low-cost base.

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.
