Inventus recovers 427 oz Au from 007 North bulk sample

Mr. Wesley Whymark reports INVENTUS RECOVERS 427 OUNCES OF GOLD AND DEMONSTRATES POSITIVE ECONOMICS FROM 007 NORTH BULK SAMPLE AT PARDO Inventus Mining Corp. has released the results from its 007 North bulk sample at its wholly owned Pardo gold project, located 65 kilometres northeast of Sudbury, Ont. Highlights: A total of 427 ounces of gold recovered from 4,674 dry tonnes for a reconciled head grade of 3.04 grams per tonne gold and a metallurgical recovery of 94 per cent; The cost of the bulk sample was approximately $1.2-million and the sale of the recoverable ounces was $2.35-million, representing a 96-per-cent return over cost; Results pending from 62 phase 2 drill holes with drilling continuing until the Christmas holidays; Anticipated processing of an additional 10,000-tonne bulk sample at the end of January, 2026. Why these results matter for investors Bulk sampling at Pardo has demonstrated the economic potential of this near-surface gold mineralization. The 007 North bulk sample has shown that, even at a pilot scale, mineralization could be extracted and processed to generate cash flow. The shallow depth of drilling required to intersect the flat-lying gold mineralization allows for rapid and cost-effective resource definition drilling, an effort currently in progress with the company's phase 2 drill program. With another 10,000-tonne bulk sample currently at the mill and 30,000 tonnes still permitted for extraction, these results indicate that additional bulk samples have the capacity to generate meaningful cash flow to further advance and derisk the project. These results reinforce the company's vision of having a near-term production profile that can eliminate or minimize shareholder dilution while advancing the project. Coming results: The next 10,000-tonne bulk sample is scheduled to run at the end of January, 2026. The continuing phase 2 drilling results are pending with 62 holes completed for 1,300 metres of drilling. Geology and mineralization: The 007 North bulk sample was extracted from a flat-lying mineralized conglomerate reef occurring at a depth of approximately three metres, with an average thickness of 1.82 metres. The mineralization occurs as disseminated pyrite and gold within the conglomerate matrix that surrounds the clasts. The unit had a sharp upper and lower contact that was easily identified in drill core and during bulk sample extraction. Grade control drilling and block model prediction: Prior to extraction of the bulk sample, the area was diamond drilled with 33 large diameter PQ size (8.5-centimetre or 3.35-inch) drill holes at 7.5-metre centres for grade estimation purposes which returned a weighted-average grade and thickness of 3.84 grams per tonne gold over 1.82 metres (see news dated June 4, 2025). Drill core samples were collected as whole-core intervals to ensure an adequate sample size for assay. Geological contacts from the drilling were used to create hard boundaries for wire framing the block model domain. Where high-grade gold was intersected near the top or bottom of the unit, a buffer of up to 25 cm was added to ensure material was not lost during extraction. Prior to extraction, the predicted block model illustrated 5,216 tonnes grading 3.95 grams per tonne gold. After extraction and using the surveyed upper and lower blast contacts, the block model illustrated a grade of 3.14 g/t gold. Bulk sample extraction: Extraction was relatively straightforward due to the mineralization being shallow and flat. The waste, consisting of a one- to six-metre flat layer, was first drilled, blasted and mucked followed by the same process of the mineralized bulk sample material. It was then crushed on site to three-fourths inch and trucked to McEwen Inc.'s stock mill. Overblasting and mucking of the southeastern corner, which had a thin layer of waste on top, resulted in the loss of material and likely the difference between the predicted block model head grades. Processing: A total of 4,816 tonnes was trucked to McEwen's stock mill near Timmins and processed from Nov. 3 to Nov. 7, 2025. Prior to and following the bulk sample run, an in-circuit inventory of gold was conducted to calculate the recoverable gold from the bulk sample. The in-circuit inventory taken after the bulk sample was subject to some uncertainty due to the short duration of the processing and the softness of the Pardo material. This difference resulted in variability of the metallurgical balance for the final reconciled head grade and recovery of the bulk sample, and is presented as ranges in the table below. As a result, the mid-range value was selected giving a total of 427 ounces of gold recovered, representing a reconciled head grade of 3.04 g/t gold and a metallurgical recovery of 94 per cent. In future, a solution to the metallurgical balance for the bulk sample results has been established and will be implemented. Bulk sample costs: The cost for the bulk sample was approximately $1.2-million or $257 per dry tonne or $2,810 per ounce (in $855,000 (U.S.) or $183 (U.S.) dry tonne or $2,000 (U.S.) per oz), which included grade control drilling, extraction, crushing, hauling and processing (minimal costs associated with Inventus personnel, and general and administrative costs were not included due to the overlap with other company activities). The bulk sample was conducted on a pilot scale, and significant operational efficiencies could be achieved in a commercial production scenario. Wesley Whymark, president and head of exploration, commented: "The 007 North bulk sample is another strong step forward for Pardo and demonstrates the economic potential of our near-surface gold mineralization. With a $4,000 gold price and three g/t gold material, the margins look good. With phase 2 drilling under way and results in the pipeline, we expect a steady flow of news as we await processing of the next 10,000-tonne bulk sample anticipated at the end of January, 2026."

Technical information The 007 North bulk sample was processed at McEwen Mining's stock mill, a fully permitted facility utilizing a conventional carbon-in-leach flow sheet. The bulk sample material entered directly into the ball mill, where feed samples were collected for grade control. The material was milled to P95 (greater than 95 per cent passing 74 micrometres) through a two-stage cyclone overflow regrind ball mill circuit and then directed into the CIL tanks, where activated carbon adsorbed gold from solution. Tails were sampled after the final CIL tank discharge to determine metallurgical efficiency. The carbon load and circuit inventories were sampled, weighed and assayed before and after the bulk sample was processed to provide Inventus with an in-circuit inventory for reconciliation of the bulk sample. Due to the short processing time and difference of typical ore material, variability of the final reconciliation resulted in uncertainty of the final grade as is presented in the table above.
