First Mining Gold Corp. Files NI 43-101 Technical Report on the Updated Mineral Resource Estimate for the Duparquet Gold Project, Quebec
First Mining Gold Corp. announced that it has filed on SEDAR a Technical Report prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") on the Duparquet Gold Project ("Duparquet" or the "Project") titled "NI 43-101 Technical Report and Mineral Resource Estimate Update for the Duparquet Project, Quebec, Canada," dated October 6, 2022 with an effective date of September 12, 2022. The Duparquet Gold Project is a multi-million ounce advanced exploration and mining development asset located in the Abitibi region of the province of Quebec, approximately 50 km north of the city of Rouyn-Noranda. The Duparquet deposit hosts a gold Resource of 3.4 Moz in the Measured and Indicated category, and an additional 1.6 Moz Au Inferred Resource derived from the master database of drill data, which contains 904 holes totaling 270,119m and 173,831 sampled intervals. Existing infrastructure at the Project site includes paved provincial highways from Rouyn-Noranda to the south and LaSarre to the north and direct access to Quebec's hydroelectric power grid. In addition, the near-by communities of Duparquet, Ruoyn-Noranda and LaSarre have strong histories of sustainable mining practices. InnovExplo Inc., the authors of the Technical Report, concluded that: The database supporting the 2022 MRE is complete, valid and up to date. Geological and gold-grade continuity has been demonstrated for all 72 mineralized zones. The key parameters of the 2022 MRE (density, capping, compositing, interpolation, search ellipsoid, etc.) are supported by data and statistical and/or geostatistical analysis. The 2022 MRE includes measured, indicated and inferred resources for a combination of two mining scenarios: open pit and selective underground. The 2022 MRE complies with CIM Definition Standards and CIM Guidelines. Two cut-off grades of 0.40 and 1.50 g/t Au were used, corresponding to potential open pit and selective underground mining scenarios. Cut-off grades were calculated at a gold price of USD 1,650 per troy ounce and an exchange rate of 1.31 USD/CAD, using reasonable mining, processing and G&A costs. In a combined pit and selective underground mining scenario, the Project contains an estimated M+I Resource of 65,081,200 t at 1.58 g/t Au for 3,316,100 oz of gold and an Inferred Resource of 37,371,900 t at 1.36 g/t Au for 1,636,000 oz of gold. The Project also contains the Beattie mine tailings with an estimated M+I Resource of 4,125,100 t at 0.94 g/t Au for 124,500 oz of gold. The results of the 2022 MRE represent a 10.5% increase in the M+I Resource and a 13.4% increase in the Inferred Resource compared to the previous 2014 MRE of Poirier et al., 2014. The increase in the M+I Resource is due to a deeper optimized shell and the updated economic parameters. The same reasons combined with the addition of 55 drill holes explain the increase in Inferred resources. Based on metallurgical tests, the Duparquet project appears amenable to standard gold recovery processes. A combination of flotation, pressure oxidation and cyanide leach processes has shown a gold recovery ranging from 94.7% to 96.5%. Additional diamond drilling on multiple zones would likely upgrade some of the Inferred Resource to the Indicated category and/or add to the Inferred Resource since most of the mineralized zones have not been fully explored at depth or close to surface infrastructures.
