Auriginal Reports Updated NI 43-101 Mineral Resource Estimate at Roger: Nearly 1.40 Million Ounces of Gold Inferred at 0.54 g/t Gold - Zone Open to Resource Expansion
Auriginal doubles its gold resource to 1.4 million ounces at the Roger deposit using a lower cut-off grade and higher metal prices.
Auriginal Mining Corp. released an updated NI 43-101 Inferred Mineral Resource Estimate for the Roger gold-copper porphyry deposit. The new estimate reports 80.5 million tonnes at 0.54 g/t Au, containing 1.39 million ounces of gold, 1.05 million ounces of silver, and 70.6 million pounds of copper.
The estimate utilizes a lower cut-off grade of 0.22 g/t Au (down from 0.45 g/t AuEq) and assumes a gold price of USD 3,750/oz. All previously classified Indicated resources have been reclassified as Inferred due to modeling changes and confidence levels.
Phase 1 and Phase 2 drilling (25 holes, ~14,875 meters) extended mineralization beyond the current model. A further resource update is targeted for Q2 2027 incorporating the new drilling and planned 2027 programs.
Auriginal Mining Corp. (AUME) announced in August 2026 that it would release an updated resource estimate by October, framing the disclosure as an expected milestone rather than a surprise. The company reported a 777% increase in contained gold, a figure driven by a lower cut-off grade and higher metal price assumptions rather than solely by new drilling.
However, the reclassification of all material to the Inferred category limits the immediate economic utility of the resource, as Indicated and Measured categories are required for preliminary economic assessments. While the news confirms the geological thesis of an expanded porphyry system, it does not materially change the company's pre-revenue status or near-term cash burn profile. Market reaction is likely to be muted as the exploration phase continues without a path to production or financing closure.
Auriginal Mining Corp. is a pre-revenue exploration company focused on gold, copper, zinc, and silver in Quebec and Atlantic Canada. Its flagship Roger Project is located in the Chibougamau district, Quebec, and hosts a dual-mineralization model consisting of a porphyry Cu-Au system and an overlying gold-rich VMS horizon. The Anik Project is a joint venture with IAMGOLD, which holds a 75% interest after exercising its earn-in option. The property is adjacent to the prolific Nelligan gold deposit. The company holds a broader portfolio of exploration properties in Atlantic Canada, though active work is concentrated on Roger and Anik.
