Cariboo Gold Project – British Columbia, Canada (100%-owned)

• Permitting Progress. Receipt of the EA Certificate in October 2023 successfully concluded the EA process for the Cariboo Gold Project (see Figure 1).
  • The BC Mines Act and Environmental Management Act permits have been drafted, and are currently under review by the Company and the Mine Review Committee.
  • The Company anticipates completing its permit application referral and receiving final construction and operating permits in Q3 2024.
  • The Company continues to explore funding options, including fully-funded solutions for the Cariboo Gold Project.

Figure 1: Cariboo Gold Project – Permitting Timeline Summary

• Pre-Construction Activities. During Q1 2024, under an existing provincial permit, the Company commenced an underground development drift from the existing Cow Portal into the Cariboo Gold Project’s mineral deposit at the Lowhee Zone. The objective of the bulk sample work program is to reach the ore body and extract a 10,000 tonne bulk sample of mineralized material for ore sorter, heavy equipment and mining testing.
  • To date, approximately 510 meters of development has been completed, with another 660 meters remaining to reach the target area.
  • The Company anticipates completing the bulk sample in Q4 2024.

• Wildfire Response. On July 22, 2024, the Company temporarily paused non-essential activities at its Cariboo Gold Project following a wildfire evacuation order that included the Project. The wildfire evacuation order was lifted on July 25, 2024, and normal course operations and site activities at the Cariboo Gold Project resumed on July 26, 2024, following the return of non-essential employees to site. The mine site infrastructure was unaffected by the wildfires.

Tintic Project – Utah, U.S.A. (100%-owned)

• Big Hill Porphyry Target Drilling. Two surface diamond drill holes totalling approximately 2,920 meters (9,581 feet have been completed at the Big Hill target area in May 2024 testing for copper-gold-molybdenum porphyry mineralization potential.
  • Both drill holes intersected porphyry systems defined by at least three late-mineral monzonite porphyritic intrusive phases and an intrusion breccia.
  • Although anomalous copper and molybdenum mineralization was encountered, including low visible presence of chalcopyrite, tennantite, and molybdenite, no significant intercepts of copper, gold or molybdenum were observed. The porphyries encountered to date are considered to lack evidence for the major fluid paths required to be the source of mineralization in the Tintic District.
  • Big Hill West Target. The results of the recent and historical drill holes suggest that the early and potentially better mineralized intrusive phase could be in an untested area immediately west and southwest of the area drilled at Big Hill.
• Trixie West Porphyry Target Drilling. One diamond drill hole was completed from underground testing porphyry-style mineralization down plunge of the mineralized structures below Trixie to a depth of 759.6 m (2,492 ft) when it crossed the Eureka Lily fault to the east and out of the prospective alteration zone.
  • These results suggest that the western hanging wall block of the Eureka Lilly fault (west of Trixie) is potentially more conducive for porphyry-style mineralization.
  • Anomalous mineralization was encountered in the drill hole; however, no significant intercepts of gold, copper or molybdenum were encountered.
• Zuma High-Potential Porphyry Target. Based on the results to date, the Zuma area has been identified as a good porphyry target that merits initial drill testing and may represent one of the causative porphyry centres of the East Tintic district.
• Lower Quartzite CRD Target. Based on the compilation of geological, drilling, and historical data, a potential large scale carbonate replacement deposit may be located below the footwall of the East Tintic thrust fault. A recommended drill program has been proposed that targets downdip extensions of known mineralization at Burgin.
• Trixie Underground Chip Sampling. The Company disclosed chip sample assays from new development areas at Trixie. Select assay highlights included (see news release dated August 7, 2024):
  • 11.07 grams per tonne gold and 25.45 g/t silver over 6.10 m in CH01716 (0.32 troy ounces per short ton Au and 0.74 oz/t Ag over 20 ft).

San Antonio Gold Project – Sonora State, Mexico (100%-owned)

• The San Antonio Gold Project remains in care and maintenance, with no production anticipated henceforth.
• The Company awaits next steps from the government of Mexico with respect to the permitting process and the status of open pit mining in the country. The approval process for environmental permits for mining may resume after the new president takes office in October 2024.
• Strategic Review. The Company is conducting a strategic review of the project and has engaged a financial advisor in connection thereof. The strategic review includes, among others, exploring the potential for a financial or strategic partner in the asset or for a full or partial sale of the asset.

SUBSEQUENT TO Q2 2024

• On July 5, 2024, the Company announced that effective July 4, 2024, as part of its annual compensation review, the Board of Directors approved the grant of an aggregate of 2,797,400 incentive stock options and an aggregate of 371,800 restricted share units to certain senior officers of the Company in accordance with the terms of the Company’s Option and RSU plans.
