Integra Resources Corp. (TSX-V:ITR) (OTCQX:IRRZF) is pleased to announce the results from recent drilling at the Company’s 100% owned DeLamar Gold-Silver Project, situated in southwest Idaho, USA, that continue to highlight mineralization well outside of the current inferred resource boundary limits. Step-out drill hole IDM18-59 in the area of Sullivan Gulch adds a further 260 meters of strike potential in an area with no previous drilling, opening the zone for further potential resource expansion.
“Drilling at DeLamar continues to show the expansion potential on what is already a large mineral endowment. This is a big system and due to little exploration work ever taking place as a result of the DeLamar Mine being in operation during a period of depressed commodity prices, Integra has been consistently discovering new, large areas of mineralization within a stone’s throw of existing infrastructure,” commented Integra CEO and President, George Salamis.
“The case for future potential resource growth at the DeLamar Project is now stronger than ever given this 260-meter step-out drill hole that hits above average grades, in fact greater than 3 times the average grade of the maiden inferred resource estimate, over a width of 109 meters. This latest drill hole now extends the Sullivan Gulch total strike length by approximately 400 meters outside of the 2018 inferred resource estimate boundary. We are particularly excited by drill hole IDM18-59 as it completely opens up the southeastern strike extension at Sullivan Gulch given that it was collared approximately 260 meters from the closest drill hole. Equally as significant, the intercept bottomed in gold-silver mineralization with a 20-meter run of over 4 grams per tonne gold equivalent, indicating that the zone is potentially thicker than demonstrated by this +100 meter wide intercept.”
DeLamar Deposit: Sullivan Gulch Zone Drill Results Summary

The geology intersected in this hole is consistent with the geology intersected in other parts of Sullivan Gulch to the north. The mineralization is largely hosted by porphyritic rhyolite and latite units, capped by a banded rhyolite formation, all of which are Miocene aged. The gold-silver mineralization itself consists of a zone of moderately intense low-sulphidation epithermal veining, clay alteration and related disseminated sulphides (mostly pyrite).
Update on Current Drill Program and Ongoing Resource Estimation Work
Given these recent results, the Company has elected to defer drilling planned for other areas of DeLamar in order to immediately focus on Sullivan Gulch infill and step-out drilling, with the goal of driving further 2019 resource expansion. Management finds it prudent to delay the commencement of the resource estimate update from Q1 2019 to Q2 2019 to allow further drilling in Sullivan Gulch. The amended drill plan is designed to test more of this highly prospective zone, with the goal of potentially including these future drill results in the next resource estimate update and subsequent Preliminary Economic Assessment.
The current drill program at Sullivan Gulch is designed to incrementally enlarge the gold-silver resource on-strike and to confirm the continuity of the zone between IDM18-59 and neighboring drill holes to the northwest. The short adjournment of the resource study will allow the result from IDM18-059, and any other infill and step-out drilling to be conducted in January and February, to be included in the 2019 resource estimate update on the DeLamar Project. This resource update will form the basis of the 2019 PEA, now scheduled for H2 2019.
Henrietta and Town Road Drill Results Summary
In addition to the successful drilling at Sullivan Gulch, the Company has been actively exploring other zones within the DeLamar Deposit, including the Henrietta and Town Road targets. Today’s results highlight strong opportunity for future resource expansion across multiple zones of the DeLamar Deposit.
A new high-grade silver-gold zone was discovered at the Henrietta Target as announced on October 10th, 2018. To view the news release, please click the following link:
Today’s drill results from drill hole IDM18-067 are situated 320 m to the northeast of the Henrietta high grade discovery hole IDM18-066. Drill hole IDM18-067 completes a fence of 3 holes on a section at Henrietta that is now 340 m wide, and open to further drill testing to the northwest and southeast.
The following table highlights selected intercepts from this tranche of drill results:
|g/t Au||g/t Ag||g/t AuEq(2)|
As drilling to date at Henrietta has highlighted a wide zone of low-grade mineralization that is open to the west and east, further drilling will be conducted in this area in 2019.
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.
