Project Update:

DeLamar Project

  • Integra recently completed a highly successful stockpile drilling program at DeLamar in April 2023. The program consisted of 321 holes, totalling 12,588 meters (“m”). Results from 9,089 m, representing 247 drill holes, have yet to be released. The Company will continue to release results from the stockpile drilling program as they are received from the lab.
    • Highlights from the drilling program include (refer to March 2023 press releases, gold equivalent (“AuEq”) = g/t gold (“Au”) + g/t silver (“Ag”) ÷ 77.7):
      • 76 m of 0.74 g/t AuEq (0.62 g/t Au and 9.54 g/t Ag)
      • 111 m of 0.59 AuEq (0.27 g/t Au and 24.60 g/t Ag)
      • 50 m of 0.67 g/t AuEq (0.34 g/t Au and 25.29 g/t Ag)
  • Integra intends to release an updated mineral resource estimate for DeLamar in Q2 2023, incorporating results from the stockpile drilling program as well as additional drilling that was completed after the cut-off date for the previous mineral resource estimate.
  • The Company expects to submit the MPO for DeLamar to the United States Bureau of Land Management (“BLM”) in Q4 2023. The submission of the MPO represents a significant milestone in the National Environmental Policy Act (“NEPA”) permitting process. Additional commentary on Integra’s permitting efforts and achievements at DeLamar is provided below.

Wildcat & Mountain View Projects

  • The Wildcat & Mountain View Projects, located in western Nevada, were acquired by Integra as part of the recently completed merger with Millennial Precious Metals Corp. (“Millennial”).
  • The Company is currently preparing an updated mineral resource estimate to incorporate Millennial’s 2021-2022 drill program of 1,250 m at Wildcat and 7,200 m at Mountain View.
    • Given the positive resource conversion results seen by the Company to date, it is expected that there will be significant conversion of resources from the Inferred category to the Indicated category in the upcoming resource estimate.
  • Highlights from the 2021-2022 drilling program at Wildcat & Mountain View include (refer to 2022 Millennial press releases):
    • Wildcat: 39.2 m of 1.26 g/t oxide Au, 41.4 m of 0.93 g/t oxide Au, and 120.2 m of 0.39 g/t oxide Au
    • Mountain View: 185.5 m of 1.48 g/t oxide Au, 128.3 m of 1.73 g/t oxide Au, and 232.5 m of 0.91 g/t oxide Au
  • Material from drilling at Wildcat and Mountain View was used for metallurgical testing, including 22 column leach tests and 186 bottle roll variability tests performed at McClelland Laboratories of Reno, Nevada. All metallurgical test work is now complete and results have met or exceeded the Company’s expectations.
  • Final mining and engineering studies are underway to support the combined maiden PEA for Wildcat & Mountain View, expected to be released in late Q2 2023.
  • Integra intends to initiate a resource expansion drill program at Wildcat in H2 2023 to test potential extensions of the oxide resource and demonstrate growth potential in previously un-explored areas surrounding the proposed main pit.
  • An Exploration Plan of Operations (“EPO”) was submitted to the BLM for both Wildcat and Mountain View in late 2022 and early 2023 respectively. The Company is working closely with the BLM to obtain the authorizations for expanded exploration programs in the future.
    • The EPO will allow for significantly increased flexibility (400 acres of surface disturbance vs. 5 acres of surface disturbance permitted under the current Notice of Operations) for future exploration, geotechnical and metallurgical drilling to support resource growth and future economic studies at Wildcat and Mountain View.

President, CEO & Director, Jason Kosec, stated, “following the transformational merger with Millennial Precious Metals, Integra now controls one of the largest precious metal resource endowments in the Western USA. Our vision is to become the next mid-tier producer in the Great Basin and 2023 will be pivotal in achieving that goal. In addition to the maiden PEA for Wildcat and Mountain View and three updated resource estimates, the Company plans to submit the Mine Plan of Operations for DeLamar. The team continues to work aggressively to unlock the full potential of these projects and continue to de-risk them through advanced metallurgy, engineering, geological and environmental baseline studies, in addition to conducting exploration focused on oxide growth.”

Executive Chairman, George Salamis, added, “Integra is committed to pursuing responsible mining development in the United States and this is reflected in our approach to de-risking and developing our key projects in Idaho and Nevada. Extensive baseline work has been underway at DeLamar for over three years, studying everything from wildlife and vegetation to air and water quality and soils. The permitting team has done an excellent job and we look forward to applying the same level of dedication to the environmental baseline, stakeholder engagement, and project development work underway at Wildcat and Mountain View.”

DeLamar Permitting Update

Integra is currently in its third and potential final year of baseline study data collection for the upcoming NEPA process subsequent to the submittal to the BLM as part of the MPO in Q4 2023. To date, Integra has established 38 surface water monitoring locations and 34 historic and new groundwater wells have been sampled quarterly since 2021, resulting in over 8 quarters of site-specific data. Baseline studies have been initiated for Wetlands, Seeps and Springs, Aquatic Resources, Air Quality, Wildlife, Vegetation, Soils, Cultural Resources, and Geochemistry in addition to Surface Water and Groundwater. To date, no federally listed threatened or endangered species have been identified in the proposed project area.

Integra has also entered into a cost recovery agreement with the BLM and initiated Agency and Tribal coordination to provide input on baseline studies to identify potential issues and alternatives in advance of the NEPA. In addition, Integra has worked with the BLM to select a third-party consultant to assist the BLM in the process of baseline plans of study review and approval, baseline data collection, and subsequent baseline technical report review in an effort to reduce the need for baseline data gap analysis and the risk of new issues or concerns arising during the scoping process.

Share Consolidation

Subject to the receipt of approval from the TSXV and NYSE American, Integra intends to consolidate its common shares (“Integra Shares”) on the basis of one post-consolidation Integra Share for every 2.5 pre-consolidation Integra Shares (the “Consolidation”). The Consolidation is currently expected to be implemented on or about May 22, 2023.

As a result of the Consolidation, Integra Shares issuable pursuant to Integra’s convertible securities will be proportionally adjusted on the same basis. No fractional share of Integra will be issued, and any fractional interest in Integra shares resulting from the Consolidation will be rounded to the nearest whole Integra share.

A letter of transmittal will be mailed to registered shareholders once the Consolidation has taken effect, which will contain instructions on how registered shareholders can exchange their share certificates or direct registration system advices (“DRS Advices”), evidencing their pre-Consolidation Integra Shares for new share certificates or DRS Advices representing the number of post-Consolidation Integra Shares to which they are entitled.
