Nuvau Minerals begins follow-up drilling at Matagami

Mr. Peter van Alphen reports NUVAU LAUNCHES FOLLOW UP DRILLING TO BRACEMAC FOOTWALL GOLD DISCOVERY IN MATAGAMI Nuvau Minerals Inc. has begun its minimum-1,500-metre (m) drill program, aimed at testing continuity and extensions to the orogenic gold system discovered last month. The discovery was made with the first hole drilled of an inaugural gold-focused exploration program, in the footwall of the Bracemac-McLeod mine, approximately 200 m below surface. The follow-up program is being drilled immediately northeast of this base metal mine, which was in production until mid-2022. The Matagami property is in the northern Abitibi region of Quebec, one of the world's most prolific gold endowed districts. This northern part of the Abitibi region includes Canada's largest gold-producing mine with the country's largest gold mineral reserves: the Detour Lake mine owned by Agnico Eagle Mines Ltd. Hecla Mining Company's Casa Berardi mine, which has produced over three million ounces of gold, is located to the southwest of the Matagami property. While the Abitibi's first recorded gold discovery was 119 years ago in Rouyn-Noranda, the Matagami property remains one of the largest areas in the region that has not been subject to a gold-focused exploration program. Previous owners were concentrating on defining and developing multiple VMS (volcanic massive sulphide) deposits into multiple mines that produced extensive copper and zinc for more than 60 years. This was one of the primary opportunities Nuvau identified when it entered into the agreement to acquire the property from Glencore. The company recently began compiling gold related historic data, as well as launching several gold-focused initiatives (including till sampling) aimed at defining initial targets for drilling. Nuvau's current gold-focused exploration program has identified three initial priority targets: Bracemac footwall discovery; Gold-in-till anomaly target; Thunder mine (1988) target. Bracemac footwall discovery The recent discovery of gold mineralization in the footwall of the Bracemac mine is located only 25 m from the access ramp of this permitted mine. The steeply dipping, strong shear zone structure with quartz veining mineralized with pyrite and locally visible gold was intersected at a depth of approximately 200 m. The visible gold was observed over approximately 0.5 m of core and assays are still pending on the discovery hole, BRCG-25-001. Although located within the immediate footwall of the past-producing Bracemac-McLeod mine, the mineralized structure occurs in a late intrusive that truncated the mine host rock units. The intrusive has seen very little drilling as the stratigraphy was not of interest for VMS exploration. The follow-up drill program is now under way to continue to step out both updip and downdip, and along strike, to test continuity of mineralization within the structural corridor, as well as providing critical data on the dip and strike of the vein. Gold-in-till anomaly target As part of Nuvau's target generative exploration program, an overburden (till) drilling program was launched in 2023. This program resulted in the discovery of significant gold-in-till mineralization that was announced on March 4, 2025. From the 2023 sonic drill program, hole PD-23-030s produced a notable gold grain anomaly detected at a depth of between 29.26 and 29.87 m in the overburden, and featured more than 2,000 gold grains per 10 kilograms (kg) of material. In addition, a near-contiguous sample with 295 gold grains per 10 kg of material between 31.12 and 32.00 m was also encountered with the interval between consisting of a large locally derived boulder. Based on the almost pristine nature of the gold grains and their close proximity to the bottom of the hole, the source is expected to be relatively close to this hole. To assist in defining targets in this area, a detailed drone MAG survey was completed. The limited rock outcrops were also mapped recently and, together with the MAG data, a drill program is being designed for later this year. The objective of this drill program will be to gain a better understanding of the local geological structures and to test for the potential source of the extensive gold grains. Thunder mine (1988) target The Thunder mine property was acquired by Nuvau in 2023 for its potential for both base metal and gold mineralization. In 1988, Thunderwood Exploration Ltd. drilled a series of holes as follow-up to a 1959 hole that intersected copper mineralization. This follow-up program identified multiple gold-bearing structures; however, no subsequent follow-up work was completed. Highlight intercepts from the available public domain report include the following: DT-14-88: 209.00 to 209.80 m (0.80 m) at 26.40 grams per tonne (g/t) gold (Au); DT-10-88: 205.00 to 206.00 m (1.00 m) at 78.16 g/t Au; DT-18-88: 100.80 to 107.30 m (6.50 m) at 1.55 g/t Au, including 0.30 m at 4.89 g/t Au; DT-19-88: 226.00 to 231.00 m (5.0 m) at 2.27 g/t Au, including 0.50 m at 10.39 g/t Au; DT-20-88: 136.80 to 137.10 m (0.30 m) at 10.37 g/t Au and 204.50 to 205.00 m (0.50 m) at 6.48 g/t Au; DT-21-88: 310.50 to 319.90 m (9.40 m) at 4.02 g/t Au, including 0.70 m at 42.03 g/t Au and 0.70 m at 7.30 g/t Au. These results been extracted from historical information and are not compliant with National Instrument 43-101. Thunder mine drilling is planned as part of Nuvau's winter drilling program in Q1 (first quarter) 2026. About Nuvau Minerals Inc. Nuvau is a Canadian mining company focused on the Abitibi region of mine-friendly Quebec. Nuvau's principal asset is the Matagami property, which is host to significant existing processing infrastructure and multiple mineral deposits, and is being acquired from Glencore. Qualified person and quality assurance Bastien Fresia, PGeo (Quebec), technical services director of Nuvau and a qualified person, as is defined by NI 43-101, has verified the scientific and technical data disclosed in this news release, and has otherwise reviewed and approved the scientific and technical information in this news release. Drill core samples are sawn by staff technicians to create half-core splits. One split is retained in the drill core box for archival purposes, with a sample tag affixed at each sample interval, and the other split is placed in a labelled plastic bag, along with a corresponding sample number tag, and placed in the shipment queue. Quality control samples, including blind certified reference material (CRM), blank material and core duplicates, are inserted at a frequency of one in every 20 samples and sample batches of up to 60 samples were then shipped directly by Nuvau personnel to the ALS Canada Ltd. preparation laboratory in Rouyn-Noranda, Que. All submitted core samples are crushed in full to 95 per cent passing less than two millimetres (mm) (ALS code CRU-32). A 1,000-gram sample was then riffled split from the crushed material and pulverized to 90 per cent passing 75 microns (SPL-22 and PUL-32a). Pulps are shipped from the preparation laboratory to ALS Canada's analytical lab in North Vancouver, B.C., for assay. Lead, silver, copper and zinc analyses were determined by ore-grade four-acid digestion with an inductively coupled plasma atomic emission spectroscopy (ICP-AES) or atomic absorption spectroscopy (AAS) finish (ALS codes Pb-OG62, Ag-OG62, Cu-OG62 and ZnOG62), whereas gold was determined by 50-gram fire assay analysis with an AAS finish (code Au-AA23).
