(TheNewswire)

Vancouver, British Columbia, November 19, 2025 TheNewswire – Prismo Metals Inc. (the ‘ Company ‘) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to report that it has completed a detailed exploration program at the Black Diamond area of its Silver King Project located in Arizona. Work consisted of mapping and sampling of the area including the Black Diamond copper replacement body and the newly encountered strongly altered felsic intrusion with stockwork veining.  A handheld XRF analyzer was used to complete a soil geochemistry grid and to analyze selected rock samples in a qualitative manner. Additionally, an IP survey was recently initiated over the Silver King land package, with results expected by the first week of December.

Figure 1 .  Map showing the location of the Black Diamond replacement and felsic intrusion exploration targets at the Silver King project.  Claim boundaries are shown in yellow.

The soil survey defined a large copper anomaly over the Black Diamond replacement body along with some anomalous gold values. Previous rock samples have shown the copper-gold association of mineralization in replacement mineralization. The soil survey also showed Zn, Pb, Ag and Sb anomalies associated with the felsic intrusion. This intrusion is strongly sericitized and is cut by moderate to strong stockwork quartz veins with locally abundant iron oxides after pyrite.

XRF analysis of rock samples in the area was also completed. Although XRF analyses on rocks are generally qualitative and are not valid assays as are rock samples assayed by the geochemical laboratories, they do indicate the presence of the metals of interest and are useful as guides to mineralization.

XRF analyses of individual quartz veinlets in the stockwork hosted by the felsic intrusion locally indicate the presence of silver, lead and zinc as well as some antimony.  During the exploration program, Prismo’s geological team took 34 rock chip samples over the area. These samples were submitted to the laboratory with assay results expected in the coming weeks.

Craig Gibson, Chief Exploration Officer of the Company, stated: ‘These results confirm Black Diamond as a copper-gold replacement body target as was indicated from previous work, making this area a compelling drill target. The data collected from the felsic intrusion indicated that it is mineralized, a feature that was not indicated in reports from previous work by Fischer Watt in 1980, although they considered it a prime target based on alteration mineralogy and fluid inclusion studies 1 .’

Drill Permit Update

Prismo also announced that the Forest Service, the federal surface land management entity for Silver King, has determined that the Company’s proposed drill plan meets the regulatory requirements for processing, and that such plan is complete, as described in the regulations at 36 CFR 228.4(c).

The Forest Service will now proceed with the environmental analysis pursuant to 36 CFR 228(a)(5) in conformity with the National Environmental Policy Act (NEPA). This analysis will proceed as a Categorical Exclusion, the lowest level of environment reviews applicable to projects that are not expected to have a significant effect on the environment, such as Silver King.

Alain Lambert, CEO of Prismo stated: ‘We are pleased with the steady progress on the permitting front, especially given the now resolved US government ‘shutdown.’

Mr. Lambert added: ‘With the closing of our recent oversubscribed financing, we are fully funded for the first two phases of drilling. In Phase 1, we plan a drill program at the historic Silver King mine site for about 1,000 meters. That drill plan is designed to test the upper half of the steeply dipping pipelike Silver King mineralized body as well as potential mineralization adjacent to the dense stockwork that was the focus of historic mining.’

Given the Company’s recent discoveries, Prismo has added a second phase of drilling for an additional 1,000 meters. This additional program will focus on the newly identified targets outside of the historic mining area, such as the polymetallic vein and the copper vein mentioned above. Drilling of the large body of replacement mineralization on the patented Black Diamond claim is also being planned and is road accessible on private ground.

About the Silver King

Discovered in 1875, the Silver King mine was one of Arizona ‘ s most important historic producers, yielding nearly 6 million ounces of silver at grades of up to 61 oz/t.  The Silver King mine sits only 3 km from the main shaft of the Resolution Copper project — a joint venture between Rio Tinto and BHP and one of the world ‘ s largest unmined copper deposits with an estimated copper resource of 1.787 billion metric tonnes at an average grade of 1.5% copper (1) . The unique land position is fully surrounded by Resolution Copper ‘ s claim block, offering strategic upside. Selected samples from small-scale production in the late 1990s returned grades as high as 644 oz/t silver (18,250 g/t) and 0.53 oz/t gold (15 g/t), indicating that high-grade mineralization remains.

Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; ‘ BRW ‘ or the ‘ Company ‘) is pleased to announce inaugural drilling results from its Anatacau Main Project, located in the Eeyou Istchee-James Bay region of Quebec. All drillholes were centered on the Anais showing and intercepted multiple, large spodumene-bearing pegmatites with rich lithium mineralization. The pegmatites are found along a major deformation corridor, reminiscent of the neighboring Galaxy deposit owned by Rio Tinto located 22 kilometers to the West.

Highlights include:

• 1.66% Li2O over 47.2 meters in drill hole AN-25-05 within a larger package of continuous lithium mineralization (present within both country rock and pegmatites) of 120.7 meters at 1.31% Li2O .
• Very high cesium values intercepted in multiple secondary sub-parallel dykes including 1.46% Cs2O over 1 meter and 0.8% Cs2O over 1 meter.
• This latest discovery is now drill traced over 170 meters of strike length and is open in all directions.

Mr. Killian Charles, President and CEO of BRW, commented: ‘Today’s exciting results underscores the opportunities across our continuously growing portfolio. We are rapidly starting to define a sizeable lithium system at Anatacau Main which, importantly, remains open in all directions. Furthermore, we are seeing mineralization constrained to the same structural corridor that is found at Rio Tinto’s Galaxy project (54.3Mt M&I at 1.30% Li2O and 55.9Mt Inferred at 1.29%, see Note ) and BRW’s Anatacau West. At Anatacau Main, we control over 18 kilometers of this highly prospective corridor which will be the focus of subsequent work in Q1 2026.

Between these strong results at Anatacau, a forthcoming maiden resource estimate for Mirage, an inaugural drill campaign in Greenland and further growth opportunities beyond the existing portfolio, Brunswick Exploration is among the most exciting companies in the lithium exploration space.’

Results Interpretation

The largest pegmatite outcrop observed at the Anais showing has now been extended to over 170 meters in strike length and to a maximum depth of 98 meters. It remains open in all direction with an apparent thickness of 47.2 meters (DDH AN-25-05) at its widest point. The main pegmatite dyke is interpreted to be dipping 85 degrees to the West. Several other, well-mineralized stacked pegmatite intervals were also intercepted in all holes, demonstrating the potential for more dyke discoveries in the vicinity of the outcrop (Figure 1). The mineralized dykes discovered at Anatacau straddle the southern side of an interpreted major deformation zone, striking northwest-southeast; a structural control that is reminiscent of the Galaxy deposit (Figure 2). The different pegmatite dykes appear to be oriented North-South to Northeast-Southwest.

The pegmatite dykes show excellent continuity in terms and mineralogy and grade, with several high-grade zones intersected to date (Table 1, Figure 3). The mineralized pegmatite dykes typically exhibit massive to coarse crystals (15+centimeters) with a mineralogy consisting of quartz, white K-feldspar, plagioclase, white spodumene, and minor amounts of muscovite, fine-grained tourmaline, and blue apatite. Spodumene crystals are inclusion-free and are consistently white unlike spodumene mineralization found at the Galaxy deposit and Anatacau West which varies from off-white to greenish. Some pegmatite intervals are under the cut-off of 0.3% Li2O but demonstrate high values of tantalum and cesium (up to 1.46% Cs2O in a 1 meter interval). This highlights the potential for other types of mineralization and by-products at the Anatacau Main project, a feature uncommon in other James Bay projects.

Host rocks consist of greywacke and amphibolite, locally deformed into schist near the deformation zone where pegmatites seem to propagate well into both units. Holmquistite, a lithium amphibole, is commonly observed in all host rocks at varying concentrations (up to 1.5% Li2O in host rock) over significant widths. This pervasive lithium alteration is potentially indicative of significant lithium bearing fluids along the deformation corridor and could be potentially used as a vectoring tool for further discoveries.

A geometallurgical study is underway at SGS using DMS (Dense Media Separation) with results expected early in 2026.

Anatacau Drilling Campaign Overview

Six (6) diamond drill holes were completed (see Figure 1 and Table 2) for a total of 750 meters. The holes were spaced by 55 to 100m, and all holes intercepted mineralized pegmatites.

The aim of the 2025 drilling campaign was to test at shallow depths (less than 150 meters vertical depth) the pegmatite dykes mapped at surface on the Anaïs showing. The drilling campaign was performed in HQ size to perform a geometallurgical study, planned according to a grant from the Ministry of Natural Resources and Forests of the Quebec Government.

Brunswick Exploration discovered the Anais showing in 2023, which consists of several parallel pegmatite dykes with visible spodumene mineralization. The largest dyke found to date is exposed over a 15 m wide by 100m long outcrop. Several grab samples returned high grade values ranging from1.19 to 3.83% Li2O on the outcrop itself (see press release dated July 13, 2023). The Anais lithium discovery is located 22 kilometers East and along strike from Rio Tinto’s Galaxy project and BRW’s Anatacau West project.

QAQC

All drill core samples were collected under the supervision of BRW employees and contractors. The drill core was transported by helicopter to the logging facility at camp Wabamisk. and by truck from the drill platform to the core logging Each core was then logged, photographed, tagged, and then packed to be shipped to Val-d’Or. Core splitting by diamond saw and sampling was done by BRW contractor at their Val-d’Or facility. All pegmatite intervals were sampled at approximately 1m intervals to ensure representativity, excluding all host rock material. Host rock was also sent for analysis 1m before and after each pegmatite interval. Samples were bagged, and blanks, pulp duplicates and certified reference materials for lithium were inserted at regular intervals. Groups of samples were placed in larger bags, sealed with numbered tags, in order to maintain a chain of custody. The sample bags were transported from BRW contractor facility to the Agat laboratory in Val-d’Or. All sample preparation and analytical work was performed by Agat Laboratories. Samples were crushed in order for 75% of the material to pass through a 2mm screen (method 200075), split to a sub-sample of 250g, and the split sample pulverized (200087) to obtain more than 85% of the material passing a 75µm screen. A sub-sample of the pulverized fraction was dissolved in a sodium peroxide solution, prior to lithium analysis by ICP-OES and ICP-MS according to the Agat method 201378. All results passed the QA/QC screening at the laboratory, and all inserted standard, duplicates and blanks returned results that were within acceptable limits. All reported drill intersections are calculated on the basis of a lower cutoff grade of 0.30% Li2O.

Skyharbour Resources Ltd. (TSX-V: SYH ) (OTCQX: SYHBF ) (Frankfurt: SC1P ) (‘Skyharbour’, ‘SYH’ or the ‘Company’) is pleased to announce that it has entered into a definitive repurchase agreement (the ‘Strategic Agreement’) with Denison Mines Corp. (‘Denison’ or ‘DML’) whereby Denison will acquire an initial project interest in Skyharbour’s Russell Lake Uranium Project (‘Russell’ or the ‘Project’) and the parties have agreed to enter into four separate joint venture agreements at closing on various claims making up Russell (the ‘Transaction’). The Project is strategically located in the central portion of the Eastern Athabasca Basin of northern Saskatchewan, with access to regional infrastructure, including an all-weather road and powerline.

Russell Lake Project Location Map:
http://www.skyharbourltd.com/_resources/images/2025-11-14%20SKY-RussellLake-Updated.jpg

Highlights:

• Strategic Agreement represents combined total project consideration of up to CAD $61.5 million consisting of cash or share payments to Skyharbour totalling up to $21.5 million (including $18.0 million before year end) plus expenditures totalling up to $40.0 million for Denison to acquire between a 20% and 70% ownership interest over seven years in the claims making up Russell, with Skyharbour owning the remaining interests.

• Denison (TSX: DML; NYSE American: DNN), a leading uranium mining company with a market capitalization of over $3 billion, is developing the Wheeler River Project (‘Wheeler River’), which shares a 55 kilometre border with Russell. Denison is an existing, large corporate shareholder of Skyharbour and now joins the Company as a strategic, active, funding partner at Russell.

• The Project will be divided into four different joint ventures, including Russell Lake (‘RL’), Getty East, Wheeler North, and the Wheeler River Inlier Claims, of which Skyharbour will retain initial ownership interests of 80%, 70%, 51%, and 30%, respectively. Denison can then earn up to a 70% interest in the Wheeler North and Getty East properties through option agreements.

• The technical teams of Denison and Skyharbour will work cooperatively to advance and unlock value across the joint ventures, employing top-tier exploration and development expertise in the region.

• Denison has committed to a minimum of $4 million in exploration expenditures over the first two years at Wheeler North and Getty East combined, as well as agreeing to fund to maintain its pro-rata 20% participation interest in the RL claims through 2029 up until such time that total exploration expenditures on the property reach $10 million.

• Skyharbour to remain operator with an 80% ownership interest at the RL claims comprising over 53,192 hectares of the original 73,314 hectare Russell Lake Project. The Company will also act as operator during the first earn-in at Getty East with Denison sole funding the exploration in order to fulfill the earn-in option criteria.

• Skyharbour to benefit with a substantial financial commitment from Denison before year end to help fund its uranium exploration and corporate activities through 2026. The Company will also generate revenue from its operator fee at the McGowan Lake exploration camp at the Project.

• Skyharbour will continue to directly advance its high-grade Moore Uranium project as well as the RL claims at Russell, while partner companies fund exploration at some of the Company’s other projects.

Jordan Trimble, President and CEO of Skyharbour, stated: ‘This is a transformative transaction for Skyharbour and our shareholders as it represents a major stamp of approval for Russell with up to $61.5 million in combined project consideration coming in. We are very pleased to expand upon our long-standing relationship with Denison and to partner with their team to advance one of the more prospective exploration projects in the Athabasca Basin proximal to existing and developing mines. Denison’s success in exploring, permitting, and developing the neighboring world-class Wheeler River Project will provide considerable insight and experience as we jointly pursue success at Russell. Further, this transaction delivers on our belief that Russell should be treated as multiple different projects due to the abundance of targets and sheer scale of the land package in one of the most prolific uranium exploration corridors in the world. The structure and terms of the Strategic Agreement allow Skyharbour to continue exploring as operator at the majority of the claims at Russell, while participating in the future success that Denison seeks as operator at the Wheeler North and Wheeler River Inlier claims. Furthermore, we will receive a significant amount of cash and Denison shares to help fund our exploration efforts and corporate activities through 2026.’

David Cates, President and CEO of Denison, further commented: ‘As Denison nears receipt of final regulatory approvals for the Phoenix In-Situ Recovery mine proposed for our flagship Wheeler River property, we are also making measured investments in our project pipeline – including our next development assets and high-potential exploration properties. Given its proximity to Wheeler River, Denison has had an interest in adding Russell to our property portfolio for much of my nearly two decades with the Company. This transaction achieves that objective by providing Denison with the opportunity to lead and participate in exploration efforts across four newly created joint ventures, which are designed to drive collaboration between Denison and Skyharbour’s technical teams. We are excited to build on our long-standing relationship with Skyharbour and accelerate the evaluation of this exceptional package of highly prospective ground.’

Reorganization of the Russell Lake Project:
https://www.skyharbourltd.com/_resources/images/Russell-Map-New.jpg

Upon closing of the Strategic Agreement, Denison will earn an initial project interest in each of the four new Russell exploration projects including a 49% interest in the Wheeler North claims, a 20% interest in the RL claims, a 30% interest in the Getty East claims, and a 70% interest in the Wheeler River Inlier claims.

1. Wheeler North (51% SYH, 49% DML ; subject to additional earn-in options ) : The yellow claims in the map above represent 16,409 hectares over eight claims. The claims host some of the exploration targets located proximal to Wheeler River, including the Grayling and Fork Zones. Upon closing of the Transaction, Denison will have the option to increase its interest in Wheeler North to a 70% interest in these claims and Denison will become the operator of Wheeler North as described in more detail below.
2. Russell Lake or RL (80% SYH, 20% DML) : The pink claims in the map above represent 53,192 hectares over 16 claims. These claims are located north and west of Skyharbour’s Moore Project and host numerous exploration target areas including Christie Lake, NE Russell, Blue Steel, Taylor Bay, South Russell, and Kowalchuk Lake. In order to maintain its initial interest in RL, Denison has agreed to fund its pro rata share of up to a maximum of C$10.0 million in total project expenditures. Upon the closing of the Transaction, Skyharbour will remain operator of RL.
3. Wheeler River Inliers (30% SYH, 70% DML) . The blue claims in the map above represent 608 hectares over two claims. These are inlier claims within Denison’s Wheeler River project hosting the West Russell and C-Block exploration target areas. DML will become operator of the Wheeler River Inliers.
4. Getty East (70% SYH, 30% DML ; subject to additional earn-in options ) . The green claim in the map above representing 3,105 hectares is host to the Little Man Lake exploration prospect. The claim borders Cameco’s Cree Zimmer property which holds its Key Lake operations to the south.  Upon the closing of the Transaction, Skyharbour will remain operator of Getty East; however, Denison will have the option to become the operator and acquire up to a 70% interest in this joint venture as described in more detail below.

Transaction Details:

The consideration payment will consist of a $2 million cash payment immediately upon execution of the Strategic Agreement (the ‘Upfront Payment’), and deferred consideration of $16 million (the ‘Deferred Consideration’) payable on or before December 31 ^st , 2025.

The Deferred Consideration shall be payable in two tranches, each of which may be paid in cash or shares of Denison at Denison’s election, including $8 million on or before the fifth business day prior to December 21 ^st , 2025, and another $8 million within 10 days of December 21 ^st , 2025. Closing of the transaction (‘Closing’) is expected to occur on or before December 21 ^st , 2025.

The current exploration camp at McGowan Lake on the Project will continue to be operated by Skyharbour and an administrative fee will be payable by Denison to Skyharbour. The claims comprising Russell are subject to various existing underlying royalties to other parties.

The Transaction is subject to customary approvals, including Skyharbour obtaining TSX Venture Exchange approval. The Transaction will be considered a Reviewable Transaction under TSX Venture Exchange policies as David Cates is a director of both Denison and Skyharbour.

Russell Lake Uranium Project Overview:

The Russell Lake Project is a large, advanced-stage uranium exploration property totalling 73,314 hectares strategically located between Cameco’s Key Lake and McArthur River Projects, and adjoining Denison’s Wheeler River Project to the west and Skyharbour’s Moore Uranium Project to the east. The northern extension of Highway 914 between Key Lake and McArthur River runs through the western extent of the property and greatly enhances accessibility, while a high-voltage powerline is situated alongside this road.

Skyharbour’s New 80% Owned RL Project:

The claims making up the RL Project constitute over seventy percent of the original Russell project area and will continue to be explored by Skyharbour as the operator and 80% owner. Denison will acquire a 20% interest and has agreed to fund to maintain its pro-rata participation interest in the RL claims through December 31 ^st , 2029, or until such time that total expenditures on the properties have reached $10 million.

The RL claims have numerous highly prospective targets that Skyharbour will continue to advance. The Christie Lake target area contains basement-hosted uranium mineralization with historical drilling returning 0.17% U ₃ O ₈ over 0.4 metres at 436.4 metres depth in hole CL-10-03, hosted within a strongly hematized breccia. A prospective clay altered basement fault system runs throughout this area.

The Blue Steel target area comprises graphitic metasediments that were last drilled in 2008. The full extent of the graphitic corridor remains unknown and completely untested. Historical geophysics indicate potential faulting along this corridor, highlighting it as a priority area for follow-up work using modern geophysical methods to refine drill targets.

The Kowalchuk area, situated within the southern Russell claims, is another prospective area on the RL claims, with multiple inferred structural trends passing through it. This area has seen only limited modern geophysical coverage to date.

In addition to the aforementioned target areas, there are many kilometres of untested EM conductors on the RL claims underlain by rocks of low magnetic intensity, suggestive of the presence of prospective graphitic meta-pelitic basement lithologies typical of Athabasca-style uranium systems. With limited modern exploration conducted over the past 12 years, the RL claims remain underexplored and highly prospective for both expanding known mineralized zones and making new discoveries.

Skyharbour has acquired from Denison Mines, a large strategic shareholder of the Company, a 100% interest in the Moore Uranium Project, which is located 15 kilometres east of Denison’s Wheeler River project and 39 kilometres south of Cameco’s McArthur River uranium mine. Moore is an advanced-stage uranium exploration property with high-grade uranium mineralization in several zones at the Maverick Corridor. Adjacent to the Moore Project is the Russell Lake Uranium Project, which hosts widespread uranium mineralization in drill intercepts over a large property area with exploration upside potential. The Company is actively advancing these projects through exploration and drilling programs.

Skyharbour also has joint ventures with industry leaders Denison Mines, Orano Canada Inc., Azincourt Energy, and Thunderbird Resources at the Russell, Preston, East Preston, and Hook Lake Projects, respectively. The Company also has several active earn-in option partners, including CSE-listed Basin Uranium Corp. at the Mann Lake Uranium Project; TSX-V listed North Shore Uranium at the Falcon Project; UraEx Resources at the South Dufferin and Bolt Projects; Hatchet Uranium at the Highway Project; CSE-listed Mustang Energy at the 914W Project; and TSX-V listed Terra Clean Energy at the South Falcon East Project.

In aggregate, Skyharbour has now signed earn-in option agreements with partners that total to potentially over $76 million in partner-funded exploration expenditures and over $42 million in cash and share payments coming into Skyharbour, assuming that these partner companies complete their entire earn-ins at the respective projects.

Skyharbour’s goal is to maximize shareholder value through new mineral discoveries, committed long-term partnerships, and the advancement of exploration projects in geopolitically favourable jurisdictions.

Ltd. (‘ Privco ‘), a British Columbia Incorporated company that holds 100% ownership, title, and interest in the Alpine Gold Property (the ‘ Property ‘), located in the West Kootenay region of British Columbia (the ‘ Acquisition ‘).

Highlights of the Alpine Gold Property

• 2018 NI43-101 Inferred Resource of 268,000 tonnes estimated using a cut-off grade of 5.0 g/t Au and an average grade of 16.52 g/t Au that represents an inferred resource of 142,000 oz of gold (McCuaig & Giroux, 2018).
• Substantial opportunity to grow the maiden Alpine resource to the east-west and to depth with only about 300m of the roughly 2km long vein system explored to date by underground mine workings and drilling.
• Estimated 24,000 tonnes Run of Mine mineralized stockpile on surface presenting a possible near term cash flow opportunity.
• 1,650 meters of clean and dry underground workings accessing sampled and mineable zones.
• At least 4 additional relatively unexplored vein systems on the Property (Black Prince, Cold Blow, Gold Crown & past-producing King Solomon), all hosting historic high-grade gold values.
• Road accessible 4,611.49-hectare Property including 15 Crown Grants (1 with surface rights) and 19 staked mineral claims with all-season operation potential (Figure 1).
• Additions of Mr. Allan Matovich to the Board of Directors. Mr. Ted Muraro and Mr. John Mirko as Technical Advisors on closing. They have a combined mining and exploration experience of 150+ years in the industry.

The 4,611.49-hectare Property is approximately 20 kilometers northeast of the City of Nelson (Figure 1) and hosts the former operating underground mine with a recorded production of approximately 16,810 tonnes of mineralized vein material (Table 1). This material contained 356,360 grams of gold, 222,054 grams of silver, 49,329 kilograms of lead and 17,167 kilograms of zinc. The other 4 significant vein systems on the property will also be explored including the Black Prince and Cold Blow quartz veins approximately 3km to the northeast of the Alpine mine, the Gold Crown vein system 600m southeast, and the past-producing King Solomon vein workings 1.8km to the south. Further information about the Alpine Gold property will be forthcoming in the upcoming weeks.

Brian Thurston, President & CEO of Copper Quest, commented : ‘ With Gold prices at all-time highs, The Alpine Gold property creates a tremendous opportunity to create near term value. I look forward to closing the transaction and welcoming Mr. Matovich, Mr. Muraro and Mr. Mirko to the team.’

Gold: Global Demand & Supply

Global demand for gold remains strong, supported by persistent geopolitical uncertainty, inflationary pressures, and ongoing central bank purchases. At the same time, supply growth is limited, with declining reserves at mature mines, few large-scale discoveries, and rising development costs. This tightening supply backdrop highlights the strategic value of advancing new gold projects in secure, mining-friendly jurisdictions. Copper Quest is aligned with these global trends, positioning Alpine to contribute to the next generation of significant gold discoveries.

Stock Options

The Company has granted stock options to Directors, Management, and Consultants of the Company to acquire an aggregate of 2,600,000 common shares in the capital of the Company, pursuant to the Company’s Equity Incentive Plan. The stock options are each convertible into a common share of the Company at an exercise price of $0. 20 until November 13, 2030.
