Inventus Mining Corp Reports Final Results from the Trench 1 Bulk Sample At Pardo Gold Project
Inventus Mining Corp. reported final results from the Trench 1 bulk sample at its 100%-owned Pardo “River of Gold” Project, located 65 km northeast of Sudbury, Ontario. The Trench 1 bulk sample was completed in two processing campaigns. The first campaign, consisting of 2,512 dry tonnes, was previously reported by the Company on March 18, 2026. The recently completed second campaign processed an additional 7,330 dry tonnes, bringing the total to 9,842 dry tonnes. 564 ounces of gold were recovered. The reconciled head grade was 2.05 g/t gold and metallurgical recovery was 87.1%. The reconciled head grade was within 3.3% of the block-model estimate of 2.12 g/t gold, achieving approximately 97% of predicted grade. The Company has now extracted and processed 20,480 tonnes through its bulk sampling programs, recovering 1,549 ounces of gold. Approximately 10,000 tonnes of mineralized material remain stockpiled and ready for processing, with all mining and crushing costs already incurred, plus a further 20,000 tonnes permitted for extraction. The 10,128-tonne Trench 1 bulk sample was extracted from near-surface mineralized conglomerate at the Pardo Gold Project and processed at McEwen Inc.’s Stock Mill near Timmins, Ontario. The first campaign processed 2,512 dry tonnes and recovered 172 ounces of gold. The second campaign processed 7,330 dry tonnes between May 27 and June 4 and recovered 392 ounces of gold. Based on the combined results from both campaigns, the full Trench 1 bulk sample is estimated to have a reconciled mill head grade of approximately 2.05 g/t gold and an overall metallurgical recovery of approximately 87.1%. Total gold sales from the Trench 1 bulk sample were approximately CAD 3,494,119. Direct bulk sample costs totalled CAD 2,281,108, equivalent to approximately CAD 232 per dry tonne processed and approximately CAD 4,042 per ounce recovered. Direct bulk sample costs included grade-control drilling, extraction, crushing, hauling and processing. Corporate G&A and Inventus personnel costs were excluded due to overlap with other Company activities. Gold sales exceeded direct bulk sample costs by approximately 53%. Pardo is a paleoplacer gold system where gold distribution can be affected by a nugget effect and local grade variability. As a result, bulk sampling is an important tool for reconciling drill-indicated grade, mining dilution, metallurgical recovery and actual gold production. Notably, the reconciled head grade from the Trench 1 bulk sample of approximately 2.05 g/t gold closely aligned with the block model estimate of 2.12 g/t gold, confirming strong alignment between predicted and actual grades. The Trench 1 bulk sample provides the Company with additional data to support: reconciliation between grade-control drilling, block model estimates and recovered gold; metallurgical recovery assumptions under operating mill conditions; mining selectivity, dilution and extraction assumptions for the shallow flat-lying gold mineralization; cost assumptions for future mine planning and economic evaluation; the Company’s upcoming mineral resource estimate. The Trench 1 bulk sample was processed at McEwen Inc.’s Stock Mill, a fully permitted facility that uses a conventional carbon-in-leach “CIL” flowsheet. The bulk sample material entered directly into the ball mill, where feed samples were collected for grade-control purposes. The material was milled through the grinding circuit and then directed into the CIL tanks, where activated carbon adsorbed gold from solution. Tailings were sampled following the final CIL tank discharge to assist with metallurgical reconciliation. Carbon load and circuit inventories were sampled, weighed and assayed before and after each bulk sample campaign to provide Inventus with an in-circuit inventory for reconciliation of the bulk sample.
