Integra Recordsdata NI 43-101 Pre-Feasibility Research Technical

VANCOUVER, British Columbia, March 28, 2022 (GLOBE NEWSWIRE) — Integra Sources Corp. (“Integra” or the “Firm”) (TSX-V: ITR; NYSE American: ITRG) has filed a technical report, ready in accordance with Nationwide Instrument 43-101 – Requirements of Disclosure for Mineral Tasks (“NI 43-101”), for its DeLamar Mission situated in southwest Idaho. Integra beforehand launched the outcomes of the Pre-feasibility Research (“PFS”) and Mineral Useful resource and Mineral Reserve assertion (see information launch dated February 9, 2022) which display a strong venture with low pre-production capital required and a robust manufacturing profile. The technical report is out there on SEDAR beneath the Firm’s profile at and on the Firm’s web site at

Key highlights of the PFS embrace:

  • After-tax Internet Current Worth (“NPV”)(5%) of US$408 million and 27% after-tax Inside Fee of Return (“IRR”) at US$1,700/ounce (“oz”) Gold (“Au”) and US$21.50/oz Silver (“Ag”) (base case).
  • After-tax NPV(5%) of US$611 million and 36% after-tax IRR at US$1,900/oz Au and US$24.00/oz Ag.
  • Pre-production Capex of US$282 million, together with contingency of 20% on processing, heap leach and tailing services (excluding working capital and reclamation prices, and assuming cellular mining gear financing).
  • Common annual manufacturing of 163,000 oz gold equal (“AuEq”)1 for first 8 years with lifetime of mine (“LOM”) common annual manufacturing of 110,000 oz Au Eq over 16 years.
  • LOM web site degree all-in sustaining prices (“AISC”) of US$955/oz on an AuEq co-product foundation, lowest quartile on a world foundation.
  • Robust leverage to silver; silver accounts for ~35% of income from manufacturing.

As acknowledged within the technical report, there may be the potential to decrease DeLamar Mission capital prices by foregoing mill processing and as an alternative function a heap-leach solely venture. On this state of affairs, a excessive proportion of the present heap-leach Mineral Reserves could be processed on the 35,000 metric tonne per day price envisioned within the PFS. LOM capital expenditures would lower considerably as growth capital, corresponding to non-oxide plant and tailing services, wouldn’t be required. A choice to assemble and provoke mill processing (Stage 2) might be exercised at any time, offering the pliability to answer altering market situations and thereby scale back venture danger. A heap-leach solely strategy might scale back danger and supply higher flexibility to answer the prevailing financial setting in reference to a call to pursue a milling state of affairs later.

Additional, the technical report highlights varied different alternatives to enhance course of recoveries and/or lower course of prices by means of continued metallurgical testing embrace:

  • Analysis of run-of-mine leaching for decrease grade oxide supplies.
  • Additional optimization of the deliberate heap-leach and mill processes could enhance recoveries and/or lower reagent consumptions.
  • Continued analysis of higher-grade oxide and blended materials varieties (notably for silver) for processing by grind-leach and flotation with focus regrind and leach, to find out if any of those supplies are higher processed by milling.
  • Ongoing optimization of the geo-metallurgical mannequin for additional optimization of ore routing to enhance recoveries.

The chance so as to add worth to the DeLamar Mission by means of the processing of the DeLamar Deposit non-oxide supplies will embrace analysis of the next:

  • Additional research on oxidative pretreatment choices corresponding to Albion processing needs to be superior with the aim of enhancing metals recoveries and venture economics. Scoping-level Albion take a look at outcomes have yielded gold and silver recoveries of 80% for Sullivan Gulch and 70% respectively for Glen Silver.
  • Analysis and optimization of flotation focus processing.
  • Additional testwork to analyze high-density or paste deposition of the flotation tailing, which might reduce the footprint and danger of the related tailings storage facility (“TSF”). Alternatives to generate energy from the tailing being pumped to the TSF may also be investigated.

There may be additionally a possibility, by means of the analysis of the historic waste dumps and backfill, for these supplies to be processed utilizing related programs outlined on this PFS. The earlier operator of the property, Kinross Gold Company (“Kinross”), halted manufacturing and started reclamation efforts at very low gold and silver costs as in comparison with present costs. As seen at many operations, these supplies could also be financial right this moment.
