(TheNewswire)

L’équipe Charbone a annoncé l’avancement des travaux de construction sur le site de son projet phare de Sorel-Tracy, se préparant aux livraisons d’équipements et au début de la production.

Brossard (Québec) TheNewswire – le 14 août 2025 – CORPORATION CHARBONE HYDROGÈNE (TSXV: CH,OTC:CHHYF OTCQB: CHHYF, FSE: K47 ) (« Charbone » ou la « Société »), une rare compagnie cotée en bourse spécialisée dans la production et la distribution d’hydrogène ultrapur vert en Amérique du Nord, est heureuse de fournir une mise-à-jour sur les progrès substantiels de la construction et les connexions d’infrastructures de son projet phare de Sorel-Tracy.

Interconnexion électrique terminée

Plus tôt cette semaine, une équipe d’Hydro-Québec a terminé l’interconnexion électrique du site. Il s’agissait de raccorder le réseau de distribution au premier poteau installé sur le site, après l’installation du poste de mesurage d’Hydro-Québec trois semaines plus tôt. L’énergie peut désormais circuler du réseau d’Hydro-Québec jusqu’à la zone de production via les lignes aériennes du site, ouvrant ainsi la voie à l’installation des équipements.

Infrastructures d’approvisionnement en eau installées

Entre-temps, le service de ses eaux de la Ville de Sorel-Tracy a terminé l’excavation et l’installation de la tuyauterie reliant le site de Charbone à une conduite d’eau principale de 14 pouces. Ce raccordement assurera une capacité d’alimentation en eau suffisante pour les cinq phases prévues du projet. Les deux principaux apports d’électricité et d’eau pour l’électrolyse étant désormais assurés, le site est prêt à démarrer la production d’hydrogène une fois l’installation des équipements terminée.

Travaux de génie civil en cours

Les machineries lourdes de génie civil sont arrivées sur le chantier, et les équipes de l’entrepreneur général et des sous-traitants de Charbone ont commencé les travaux. Les arpenteurs géomètres ont terminé le marquage du site nécessaire à la construction des bâtiments et des zones de production, en prévision de l’arrivée des équipements dans les semaines à venir.

Gestion de l’environnement

Lors de la préparation du site, le ministère de l’Environnement du Québec (MELCCFP) a identifié une espèce végétale rare et menacée – l’Aristide à rameaux – sur une petite partie de la propriété. En collaboration avec les experts de Tetra Tech, Charbone a réussi à relocaliser et à protéger la plante, lui assurant ainsi un habitat dédié sur le site. « Cette mise à jour marque la réalisation de trois étapes cruciales pour notre équipe », a déclaré Dave Gagnon, président-directeur général de Charbone. « Nous sommes fiers des progrès réalisés à ce jour et maintenons le cap pour le début de la production cet automne. »

Undrilled silver-rich and polymetallic occurrences are dispersed across a 55 km highly prospective east-west corridor

Silver47 Exploration Corp. (TSXV: AGA,OTC:AAGAF) (OTCQB: AAGAF) (‘Silver47’ or the ‘Company’) is pleased to provide a review of drill targeting across the highly-prospective Bonnifield District at the Red Mountain project near Fairbanks, Alaska (the ‘Red Mountain Project’).

Highlights:

• Strong Alaskan High-Grade Resource Base: The Red Mountain Project already hosts an inferred mineral resource estimate of 15.6Mt at 336 g/t AgEq* totaling 168.6 million silver equivalent ounces comprised of two resource zones, Dry Creek and West Tundra Flats.

• Leveraging Past Work: A database of historic geochemical and geophysical data, including 2,543 rock samples, 7,948 soil samples and 15,862 XRF soil samples has revealed a series of new targets outside the current resource zones that the Company is developing for drilling in 2026.

• High Prospectivity and Unique Discovery Potential: Ongoing compilation highlights at least 35 mineralized prospects across the Red Mountain Project covering a 55 km trend many of which are undrilled or represent preliminary drilled discoveries open to expansion.

• U.S. Silver and Critical Metal Focus: Multiple zones of high-grade surface mineralization marked by samples collected by a previous operator representing significant polymetallic upside are highlighted by grades of:

• 1,295 g/t silver at the Galleon target
• 3.8 g/t gold at the Horseshoe target
• 16.2% copper at the Kiwi target
• 32% zinc at the Anderson Mountain target
• 20% lead at the Jack Frost target
• 4,850 g/t antimony at the Bib target
• 149 g/t gallium northeast of the West Tundra Flats Deposit
• 98 g/t indium at the Jack Frost target
• 0.13% tin at the Sheep Creek target

• Drilling On-Going with Assays Pending: Nine holes have been completed at the Dry Creek and West Tundra Flats deposits where zones of massive, semi-massive and disseminated sulfides have been intersected in step-out and infill holes.

Galen McNamara, CEO, stated: ‘Our Red Mountain Project in Alaska is emerging as a premier silver and critical metals asset in the U.S. By leveraging extensive historic data, we’ve identified dozens of high-potential targets along broadly mineralized trends. The prospectivity of these targets was first identified by past operators, and I agree; the data suggest the likely presence of additional undiscovered and potentially giant VMS deposits on the project. I am unaware of any other domestic mineral projects with similar polymetallic discovery potential. In addition, ongoing drilling at Dry Creek and West Tundra Flats continues to intersect promising sulfide zones, with assays pending, positioning Red Mountain to deliver significant value and strengthen domestic critical mineral supply chains in the future.’

1. The 2024 Red Mountain MRE was estimated and classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (‘CIM’) ‘Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines’ dated November 29, 2019, and the CIM ‘Definition Standards for Mineral Resources and Mineral Reserves’ dated May 10, 2014.
2. Mr. Warren Black, M.Sc., P.Geo. of APEX Geoscience Ltd., a QP as defined by NI 43-101, is responsible for completing the 2024 Mineral Resource Estimate, effective January 12, 2024.
3. Mineral resources that are not mineral reserves have not demonstrated economic viability. No mineral reserves have been calculated for Red Mountain. There is no guarantee that any part of the mineral resources discussed herein will be converted to a mineral reserve in the future.
4. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, market, or other relevant factors.
5. The quantity and grade of reported Inferred Resources is uncertain, and there has not been sufficient work to define the Inferred Mineral Resource as an Indicated or Measured Mineral Resource. It is reasonably expected that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
6. All figures are rounded to reflect the relative accuracy of the estimates. Totals may not sum due to rounding. Reported grades are undiluted.
7. A standard density of 2.94 g/cm³ is assumed for mineralized material and waste rock. Overburden density is set at 1.8 g/cm³. For mineralized material blocks with iron assays close enough to estimate an iron value for the block, density is calculated using the formula: density (g/cm³) = 0.0553 * Fe (%) + 2.5426.
8. Metal prices are US$2,750/tonne Zn, US$2,100/tonne Pb, US$8,880/tonne Cu, US$1,850/oz Au, and US$23/oz Ag.

The Targets

Priority volcanogenic massive sulfide (VMS) exploration targets at the Red Mountain Project are dispersed across the highly prospective Bonnifield mining district. The targets vary from zinc-rich to copper-rich and many have associated high-grade silver and local gold mineralization.

Four main target trends are defined and include: Dry Creek Syncline, Keevy Trend, Last Chance Corridor and Wood River trend (Figure 1). Many of the targets across the Dry Creek Syncline area (Figure 1) were known historically, however, numerous high-priority targets across the Keevy and Last Chance areas were more recently identified through regional stream sediment, ridge-spur soil and rock geochemical surveys and project-wide EM geophysical surveys completed by a past project operator. Of the 30 known targets as well as other un-explored EM targets, only eleven targets have been drill tested, five of those with less than three holes each.

The Dry Creek Syncline: The best known targets associated with the Dry Creek Syncline are the Dry Creek and WTF deposits (combined inferred mineral resource of 15.6 million tonnes at 7% ZnEq or 335.7 g/t AgEq, totaling 168.6 million silver equivalent ounces*). Previous drilling at Dry Creek have returned high-grade intercepts, such as 22.3 m at 601 g/t AgEq (150.6 g/t Ag, 0.82 g/t Au, 5.86% Zn, 2.60% Pb, 0.13% Cu, DC24-105) from 18.9 m down hole.

VMS targets are located along both limbs of the project-scale, east-west trending Dry Creek syncline where approximately 40 km of prospective VMS stratigraphy (Mystic and Sheep Creek members of the Totatlanika schist) is well exposed (Figure 1). Many targets along the syncline are associated with pronounced EM anomalies and have been mostly defined by stream, soil and rock-chip geochemistry and limited ground geophysical surveys (magnetics and CSAMT). High priority targets across the Dry Creek Syncline area include:

• Hunter Target: Massive sulfide mineralization at the Hunter target, 5.8 km west of Dry Creek, has been traced for over 500 m within a carbonaceous phyllite that is traced for over 1 km. Rock chip sampling of the discovery Hunter outcrop returned assays up to 616 g/t Ag, 18.6% Zn, 5.4% Pb, 2.5% Cu, and 0.33 g/t Au. Six drill holes in 2018, 2019 and 2021 successfully tested the dip-extent of the massive sulfide lens highlighted by 1.4m of 17.4% Zn, 3.9% Pb, 1.6% Cu, 90 g/t Ag and 0.23 g/t Au (HR18-01)² and 1.8m of 13.8% Zn, 3.1% Pb, 56 g/t Ag, 0.2 g/t Au and 0.9% Cu (HR18-02)². VMS-related mineralization at Hunter is therefore open in all directions and further drilling testing of the strike- and dip-extent is warranted.

• Glacier Creek: The Glacier Creek suite of targets are approximately 12.3 km northwest of Dry Creek. The ~6 km long target area is primarily underlain by the highly-prospective Totatlanika schists and is defined by numerous EM anomalies and broad km-scale colour anomalies and associated sericite alteration. Rock-chip sampling is sparce and soil-surveys have only been ridge-spur, however, numerous multi-element geochemical anomalies have been defined together with barium enrichment in many samples. Seven holes were drilled across two programs covering a 2 km trend in 1998 and 2019. Additional geological mapping, soil and rock geochemical surveys are clearly warranted to advance the known targets and to define drill targets.

• Galleon Target: The Galleon target is approximately 9.0 km north of Dry Creek. Similar to Glacier Creek, the Galleon target is primarily underlain by the Totatlanika schist where numerous showings of VMS-style, high-Pb-Zn-Cu massive sulfide mineralization have been discovered. Importantly, numerous samples from Galleon returned elevated to high-grade Ag and Au mineralization. Rock samples with up to 1,265 g/t Ag, 2.18 g/t Au, 2.4% Zn, 1.656% Pb and 1.7% Cu have been reported. Additional geological mapping, soil and rock geochemical surveys are clearly warranted to advance the known targets, followed by drill testing.

The Keevy Trend: The Keevy VMS trend consists of numerous high-grade VMS targets dispersed along 25 km of favorable Keevy Peak Formation and Healy Schist stratigraphy south of the Dry Creek Syncline area (Figure 1). From east to west the targets comprise Lowrider, Easy Ivan, Jack Frost, Yogi, Kiwi, and Yeti with multiple unexplored EM targets west of Yeti (Figure 1). These targets have massive sulfide occurrences comprised of sphalerite, galena and chalcopyrite with other key VMS indicators such as chert, black barite and broad zones of sericite alteration and strongly anomalous base-metal soil anomalies. Highlights and key indicators of VMS potential from the Keevy VMS trend include:

• Kiwi: up to 316 g/t Ag, 16.2% Cu, 10.3% Zn, 1.7% Pb, and 2.8 g/t Au in rock samples

• Easy Ivan: up to 87.1 g/t Ag, 6.0% Zn, 12.3% Pb, and 0.45% Cu in rock samples

• Jack Frost: up to 285 g/t Ag, 14.0% Zn, 20.0% Pb, and 1.1% Cu in rock samples

• Yeti: black barite with elevated silver and strong base metal soil anomalism

Besides sparce ridge-spur and local grid soil surveys, prospecting and rock sampling many of the targets are under-explored and represent priority targets for follow-up. Geological mapping and infill soil geochemical surveys are planned to advance many of the targets along the highly prospective Keevy Trend.

Last Chance Corridor: The Last Chance area of prospective VMS targets is centered approximately 40 km west of the Dry Creek deposit (Figure 1). These targets may represent the western extent of the Keevy Trend. Seven targets have been defined covering a prospective corridor of 15 km primarily underlain by the Healy Schist and include from east to west; Copper Creek, Grapple, Bib West, Bullseye, Ringer, Sheep Creek and Horseshoe. The VMS lenses exposed in outcrop consist of pyrrhotite, pyrite and/or sphalerite, galena and chalcopyrite. Only the Sheep Creek target has been drill tested (1979 program by US Borax¹) and all targets are primarily defined based on rock, soil and stream sediment anomalism and airborne and local ground-based geophysical methods. Highlights from previous rock-chip sampling include:

• Horseshoe: up to 8.3% Zn, 4.6% Pb, 0.76% Cu, 44 g/t Ag and 3.8 g/t Au in rock samples

• Bib: up to 7.3% Zn, 5.1% Pb, 0.3% Cu, 60 g/t Ag and 0.47 g/t Au in rock samples

• Grapple: up to 5.1% Zn, 13.2% Pb, 0.79% Cu and 139 g/t Ag in rock samples

• Ringer: up to 0.72% Cu, 27 g/t Ag and 1.0 g/t Au in rocks samples

• Sheep Creek: up to 306 g/t Ag, 4.3% Zn, 3.98% Pb, and 0.18% Cu in rock samples and 24.5 m of 1.3% Zn,1.0% Pb and 0.127% Sn in historical drilling¹

Follow-up geological mapping, infill soil geochemical surveys and additional higher-resolution magnetic surveys are planned to further advance many of the Last Chance targets.

Wood River Trend: Four high-grade VMS targets cover a 24 km trend on the southern limb of a district-scale anticlinal fold that runs parallel to the Dry Creek syncline (Figure 1). The targets are hosted in prospective Healy and Wood River Assemblage schists which host VMS-related mineralization elsewhere in the Bonnifield district. From east to west the targets include West Fork, Cirque, Virginia Creek and Anderson Mountain. Select historical rock-chip sampling and select drilling highlights include:

• West Fork: up to 3.5% Zn, 2.5% Pb, 1.2% Cu and 73g/t Ag in rock samples

• Cirque: up to 487 g/t Ag, 13.2% Zn, 3.8% Pb, 12.4% Cu and 3.7 g/t Au in rock samples

• Virginia Creek: historical drilling, 14.8m at 3.3% Zn, 0.8% Pb, 78 g/t Ag, 0.2g/t Au and 0.5% Cu¹ and rock samples up to 2.8% Zn, 0.65% Pb, 74.1 g/t Ag, 1.01 g/t Au and 1.3% Cu

• Anderson Mountain: historical drilling, 161 g/t Ag, 0.6 m at 22% Zn, 4.8% Pb and 0.6% Cu¹ and up to 151 g/t Ag, 32% Zn, 8.8% Pb and 3.8% Cu in rock samples. The prospective VMS horizon is mapped for over 240 m

Follow-up geological mapping, infill soil geochemical surveys and additional higher-resolution magnetic surveys are warranted to further advance many of the Wood River trend of VMS targets.

Osisko Metals Incorporated (the ‘ Company or ‘ Osisko Metals ‘) ( TSX-V: OM ; OTCQX: OMZNF ; FRANKFURT: 0B51 ) is pleased to announce new drill results from the Gaspé Copper Project, located in the Gaspé Peninsula of Eastern Québec.

Osisko Metals Chief Executive Officer Robert Wares commented: ‘ Drill results at Gaspé Copper continue to exceed expectations. These new data expand the deposit further south and at depth with drill holes 30-1092 and 30-872, located respectively 230 metres and 440 metres south of the 2024 Mineral Resource Estimate (‘MRE’) model. Additional holes are planned in this resource expansion target area in the coming months over a surface of 450 metres by 550 metres, which we believe will add significant new tonnage to the MRE update, planned for Q1 2026. ‘

New analytical results are presented below (see Table 1), including 20 mineralized intercepts from 7 new drill holes. Infill intercepts are located inside the 2024 MRE model ( see November 14, 2024 news release ), and are focused on upgrading inferred mineral resources to measured or indicated categories, as applicable. Expansion intercepts are located outside the 2024 MRE model and may potentially lead to additional resources that will be classified appropriately within the next MRE update. Some of the reported intercepts have contiguous shallower infill as well as deeper expansion (noted on Table 1 below as ‘Both**’). Maps showing hole locations are available at www.osiskometals.com .

Highlights:

• Drill hole 30-1096
  • 730.7 metres averaging 0.29% Cu (infill and expansion)
• Drill hole 30-1085
  • 219.0 metres averaging 0.41% Cu (infill)
  • 754.5 metres averaging 0.24% Cu (infill and expansion)
• Drill hole 30-1092
  • 331.5 metres averaging 0.37% Cu (expansion)
• Drill hole 30-1095
  • 309.5 metres averaging 0.26% Cu (infill)
• Drill hole 30-1098
  • 115.0 metres averaging 0.29% Cu (infill)
  • 124.5 metres averaging 0.20% Cu (expansion)

• Drill hole 30-1099
  • 614.7 metres averaging 0.23% Cu (infill and expansion)
• Drill hole 30-0872
  • 92.1 metres averaging 0.24% Cu (expansion)
  • 47.2 metres averaging 1.14% Cu (expansion)

Table 1: Infill and Expansion Drilling Results

* See explanatory notes below on copper equivalent values and Quality Assurance / Quality Control.
** ‘Both’ indicates drill holes that have contiguous shallower infill as well as deeper expansion intercepts.

Discussion

Drill hole 30-0872 was an old Noranda hole from the 1990s from which core was recovered and analyzed. The hole is located 440 metres south of the southern limit of 2024 MRE model and returned 92.1 metres averaging 0.24% Cu and 3.05 g/t Ag followed by a higher grade second intercept of 47.2 metres averaging 1.14% Cu and 11.8 g/t Ag (at the level of the C Zone skarn horizon), extending mineralization to a vertical depth of 390 metres. The first intercept starts at a depth of 168 metres and the overlying stratigraphy (Indian Cove hornfels) is unmineralized, but this waste material may be included as necessary strip in the next Whittle pit shell.

Drill hole 30-1085, located on top of Copper Mountain near the central part of the 2024 MRE model, intersected 219.0 metres averaging 0.41% Cu and 2.79 g/t Ag (infill), followed by a second intercept (starting 130 metres deeper) of 754.5 metres averaging 0.24% Cu, 1.63 g/t Ag and 0.019% Mo (both infill and expansion at depth).This hole extends mineralization near the centre of the deposit to a vertical depth of 1110 metres.

Drill hole 30-1092 is located 230 metres south of the southern limit of 2024 MRE model and returned 331.5 metres averaging 0.37% Cu and 3.21 g/t Ag (from surface down to the P4 stratigraphic level below the C Zone). This hole is located approximately 15 metres west of previously-reported hole 30-1067, which had failed to drill through a pillar of the B Zone.

Drill hole 30-1095, located in the south-central part of the 2024 MRE model, intersected 309.5 metres averaging 0.26% Cu and 2.11 g/t Ag (infill). This was followed by 56.1 metres averaging 0.23% Cu and 1.70 g/t Ag and then by another 21.9 metres averaging 0.42% Cu and 2.04 g/t Ag (both expansion), extending mineralization to a vertical depth of 550 metres.

Drill hole 30-1096, located in the central part of the 2024 MRE model, intersected two short (51 and 48 metre-long) mineralized zones, followed by 730.7 metres averaging 0.29% Cu, 1.60 g/t Ag, and 0.032% Mo (0.42% CuEq). The latter includes an expansion lower intercept, below the base of the 2024 MRE model, of 334.7 metres averaging 0.39% Cu, 1.79 g/t Ag, and 0.032% Mo (0.52% CuEq). This hole extends mineralization to a vertical depth of 1062 metres.

Drill hole 30-1098, located near the western margin of the 2024 MRE model, intersected 104.5 metres averaging 0.20% Cu and 2.25 g/t Ag (infill), followed by 115.0 metres averaging 0.29% Cu and 2.18 g/t Ag (infill). This was followed by 124.0 metres averaging 0.20% Cu and 1.57 g/t Ag and then by another 60.0 metres averaging 0.35% Cu and 2.88 g/t Ag (both expansion), extending mineralization to a vertical depth of 813 metres.

Drill hole 30-1099, located near the central part of the 2024 MRE model, adjacent to the Copper Mountain pit, intersected a short (34-metre-long) mineralized zone followed by 614.7 metres averaging 0.23% Cu, 1.59 g/t Ag, and 0.016% Mo (both infill and expansion), followed by a third intersection of 138 metres that averaged 0.13% Cu, 1.01 g/t Ag, and 0.028% Mo (expansion), extending mineralization in the porphyry core of the deposit to a vertical depth of 1000 metres.

Mineralization at Gaspé Copper is of porphyry copper/skarn type and occurs as disseminations and stockworks of chalcopyrite with pyrite or pyrrhotite and minor bornite and molybdenite. At least five retrograde vein/stockwork mineralizing events have been recognized at Copper Mountain, which overprint earlier prograde skarn and porcellanite-hosted mineralization throughout the Gaspé Copper system. Porcellanite is a historical mining term used to describe bleached, pale green to white potassic-altered hornfels. Subvertical stockwork mineralization dominates at Copper Mountain whereas prograde bedding-replacement mineralization, that is mostly stratigraphically controlled, dominates in the area of Needle Mountain, Needle East, and Copper Brook. High molybdenum grades (up to 0.5% Mo) were locally obtained in both the C Zone and E Zone skarns away from Copper Mountain.

The 2022 to 2024 Osisko Metals drill programs were focused on defining open-pit resources within the Copper Mountain stockwork mineralization ( see May 6, 2024 MRE press release ). Extending the resource model south of Copper Mountain into the poorly-drilled prograde skarn/porcellanite portion of the system subsequently led to a significantly increased resource, mostly in the Inferred category ( see November 14, 2024 MRE press release ).

The current drill program is designed to convert the November 2024 MRE to Measured and Indicated categories, as well as test the expansion of the system deeper into the stratigraphy and laterally to the south and southwest towards Needle East and Needle Mountain respectively. The November 2024 MRE was limited at depth to the base of the L1 skarn horizon (C Zone), and all mineralized intersections below this horizon represent potential depth extensions to the deposit, to be included in the next scheduled MRE update in Q1 2026.

All holes are being drilled sub-vertically into the altered calcareous stratigraphy which dips 20 to 25 degrees to the north. The L1 (C Zone) the L2 (E Zone) skarn/marble horizons were intersected in most holes, as well as intervening porcellanites that host the bulk of the disseminated copper mineralization.
