• Drill outcomes from Sullivan Gulch (situated on the japanese portion of the DeLamar Deposit) and Sommercamp-Regan at DeLamar embrace:
  • IDM-22-204 – Sullivan Gulch
    • 0.57 grams per tonne (“g/t”) gold (“Au”) and 131.29 g/t silver (“Ag”) (2.26 g/t gold equal (“AuEq”)) over 102.11 meters (“m”)
      • Together with 0.78 g/t Au and 875.25 g/t Ag (12.05 g/t AuEq) over 6.09 m
      • Together with 1.30 g/t Au and a couple of,718 g/t Ag (36.28 g/t AuEq) over 1.53 m
      • Together with 0.46 g/t Au and 176.01 g/t Ag (2.73 g/t AuEq) over 12.19 m
  • IDM-22-206 (the primary 100 m is thru historic Backfill) – Sommercamp-Regan (Most important DeLamar Pit space)

• These drill holes, which had been a part of a metallurgical drill program and reveal the robust continuity of gold-silver on the Undertaking, additionally lengthen the recognized mineralization at Sullivan Gulch by 30 m.
• The primary 100 m of drill gap IDM-22-206 examined historic backfill and encountered robust AuEq grades that might additional complement future heap leach plans, offering extra proof that these low-grade stockpiles and backfill at DeLamar and Florida Mountain have the potential to extend the Oxide-Blended useful resource on the Undertaking.
• A portion of the high-grade intercepts introduced right this moment proceed to outline the just lately found high-grade Northwest putting gold-silver zone that underlies the majority tonnage low-grade useful resource at Sullivan Gulch, with continuity within the North zone of 350 m and the South zone of 350 m.

VANCOUVER, British Columbia, July 21, 2022 (GLOBE NEWSWIRE) — Integra Sources Corp. (“Integra” or the “Firm”) (TSX-V: ITR; NYSE American: ITRG) is happy to announce drill outcomes from the DeLamar Undertaking (“DeLamar” or the “Undertaking”) situated in southwestern Idaho. The drill outcomes introduced right this moment embrace lengthy runs of robust mineralization at DeLamar, together with a number of high-grade hits of silver. Drill gap IDM-22-207 prolonged mineralization beneath the Pre-feasibility Examine (“PFS”) Pit Constrained Useful resource by 30 m and drill gap IDM-22-206 demonstrated the potential for useful resource within the historic stockpiles and backfill on the Undertaking.

“Integra continues to be very lively on the bottom and continues to execute on our said goal of displaying useful resource progress potential on a myriad of exploration fronts at DeLamar whereas advancing the Undertaking in the direction of allowing. The drill holes introduced right this moment proceed to outline Sullivan Gulch as an excellent, prolific gold-silver goal with substantial upside for future mining and processing eventualities. Sullivan Gulch is outlined by a 100 m to 300 m broad thicknesses of disseminated low-grade, gold-silver mineralization underlain by a newly found high-grade gold-silver zone. This high-grade zone is open to the south, laterally, and at depth, complimenting the majority tonnage useful resource above it, “famous President and CEO George Salamis. “Right now’s intercept extends mineralization beneath the PFS useful resource pit by 30 m. As well as, the brand new high-grade zone has now been intercepted over a vertical extent of 215 m, and alongside a strike size of 350 m within the Northern zone and 350 m within the Southern zone. There stays a 370 m untested hole between the Northern and Southern high-grade zones, presenting an apparent excessive precedence drill goal.”

The next desk highlights chosen intercepts from the Sullivan Gulch drill outcomes introduced right this moment:

(1)   Downhole thickness: true width varies relying on drill gap dip; most drill holes are aimed toward intersecting the vein constructions near perpendicular due to this fact true widths are near downhole widths (roughly 70% conversion ratio)(2)   Gold equal = g Au/t + (g Ag/t ÷ 77.70)(3)   Intervals reported are uncappedSullivan Gulch:

Together with demonstrating the magnitude of the big low-grade gold-silver zone at Sullivan Gulch, the drill outcomes introduced right this moment proceed to broaden the rising high-grade vein system at Sullivan Gulch that developments Northwest and dips to the Northeast. This new discovery additional enriches the high-grade element of Sullivan Gulch, the majority of which dips to the Southwest. Excessive-grade at Sullivan Gulch has been intercepted in a Northern zone over a 350 m strike size whereas the Southern zone, which incorporates intercepts from 2018 to current which align with the brand new geological mannequin, additionally has a strike size of 350 m. There stays a 370 m untested zone between the North and South high-grade zones which has the potential to increase the strike size of this high-grade goal to over 1,000 m. These intercepts additional validate the geological mannequin that along with a well-defined North-northwest trending vein system that dips to the Southwest which has seen many of the drilling at Sullivan Gulch, there exists a structurally managed system in quartz latite that dips Northeast and is open to the south, laterally, and at depth.

Generally, the mineralization at Sullivan Gulch is essentially hosted by porphyritic rhyolite and latite models, capped by a banded rhyolite formation, all of that are of mid-Miocene age. The gold-silver mineralization itself consists of a zone of reasonably intense low-sulphidation epithermal veining, clay alteration and associated disseminated sulphides (largely pyrite). IP signifies the potential for mineralization to increase an extra 900 m to the south of the southern-most drilled part of Sullivan Gulch.

Historic Stockpiles and Backfill:

Drill gap IDM-22-206 is of specific significance to Integra because it supplies extra proof that the historic low-grade stockpiles and backfill at DeLamar and Florida Mountain are mineralized and will present extra heap leach materials in future mine plans. The Firm estimates that 60 million tonnes of run-of-mine, low-grade Oxide materials is stockpiled and/or used as backfill in a number of areas on the Undertaking from its 20-year historical past of contemporary mining (Nineteen Seventies-Nineteen Nineties). Based mostly on the Firm’s reconciliation of milling data and the reconstruction of mined materials, the Firm believes this materials exceeds the heap leach cut-off grades and has the potential so as to add mine life to the longer term operations.

The primary 100 m of drill gap IDM-22-206 was by way of historic backfill, returning common AuEq grades in-line with Firm estimates and probably appropriate for heap leach materials, topic to additional research. Encountering these leads to the primary drill gap into historic backfill is encouraging.

Summer time Work Program and Subsequent Steps:

Following a quick pause, the Firm expects to recommence drilling at DeLamar this summer season. The proposed summer season/fall drill program is being executed totally on DeLamar personal property on historic patented mining claims and is able to proceed on the Firm’s discretion.

Sampling and QA/QC Process

Thorough QA/QC protocols are adopted on the Undertaking, together with insertion of duplicate, clean and commonplace samples within the assay stream for all drill holes. The samples are submitted on to American Assay Labs in Reno, Nevada for preparation and evaluation. Evaluation of gold is carried out utilizing hearth assay methodology with atomic absorption (AA) end on a 1 assay ton aliquot. Gold outcomes over 5 g/t are re-run utilizing a gravimetric end. Silver evaluation is carried out utilizing ICP for outcomes as much as 100 g/t on a 5-acid digestion, with a hearth assay, gravimetric end for outcomes over 100 g/t silver.
