Integra Resources Corp. announced drill results from the DeLamar Project (“DeLamar” or the “Project”) located in southwestern Idaho. The drill results announced include long runs of strong mineralization at DeLamar, including multiple high-grade hits of silver.

Drill hole IDM-22-207 extended mineralization below the Pre-feasibility Study (“PFS”) Pit Constrained Resource by 30 m and drill hole IDM-22-206 demonstrated the potential for resource in the historic stockpiles and backfill at the Project. Along with demonstrating the magnitude of the large low-grade gold-silver zone at Sullivan Gulch, the drill results announced continue to expand the emerging high-grade vein system at Sullivan Gulch that trends Northwest and dips to the Northeast. This new discovery further enriches the high-grade component of Sullivan Gulch, the bulk of which dips to the Southwest.

High-grade at Sullivan Gulch has been intercepted in a Northern zone over a 350 m strike length while the Southern zone, which includes intercepts from 2018 to present which align with the new geological model, also has a strike length of 350 m. There remains a 370 m untested zone between the North and South high-grade zones which has the potential to extend the strike length of this high-grade target to over 1,000 m. These intercepts further validate the geological model that in addition to a well-defined North-northwest trending vein system that dips to the Southwest which has seen most of the drilling at Sullivan Gulch, there exists a structurally controlled system in quartz latite that dips Northeast and is open to the south, laterally, and at depth. In general, the mineralization at Sullivan Gulch is largely hosted by porphyritic rhyolite and latite units, capped by a banded rhyolite formation, all of which are of mid-Miocene age. The gold-silver mineralization itself consists of a zone of moderately intense low-sulphidation epithermal veining, clay alteration and related disseminated sulphides (mostly pyrite).

IP indicates the potential for mineralization to extend a further 900 m to the south of the southern-most drilled section of Sullivan Gulch.
