Blue Sky Uranium Corp. (TSXV: BSK,OTC:BKUCF) (FSE: MAL2) (OTCQB: BKUCF), ‘Blue Sky’ or the ‘Company’) is pleased to announce that the Company has launched a 1,200-metre diamond drilling program at the Ivana Gateway target (formerly Ivana Gap), located 4700 metres northwest of the Ivana deposit, within the Amarillo Grande Uranium-Vanadium district, Río Negro Province, Argentina (‘AGP’).

In October 2025, the Company completed a 5 km pole-dipole ET geophysical survey at Ivana Gateway, which delineated a 1.4 km-wide chargeability anomaly interpreted as the extension of the redox front system present at Ivana. The aim of the current program is to test for mineralization and/or geochemical vectors related to a northern extension to the Ivana uranium deposit. The program will drill a fence of holes spanning 4300 metres, testing the interpreted redox front. Contractor AGV Falcon Drilling is executing the program and all holes are being drilled using HQ-diameter core. The drilling program was initiated in late October and 11 holes have been completed to date out of 19 planned (see Figure 1). Drill core logging and sampling is ongoing, and analytical results will be released once received and interpreted.

Nikolaos Cacos, Blue Sky President & CEO commented, ‘We are pleased to be drilling a new priority target on Blue Sky’s 100% held concessions close to the Ivana deposit. We continue to refine and test our exploration model for the Amarillo Grande project, which we believe has the potential to host multiple deposits similar to Ivana.’

The Ivana Gateway target is located on concessions held by Blue Sky via its 100% owned subsidiary, Minera Cielo Azul S.A. (‘MCA‘). This drilling program is funded by Ivana Minerales S.A. (‘IMSA‘) the joint venture company (‘JVCO‘) established to advance the Ivana Uranium-Vanadium Project. Under the terms of the definitive agreement announced on December 2, 2024 IMSA has the exclusive right and option (‘Call Option‘) to acquire up to a 100% interest in certain exploration targets (‘Exploration Targets‘) at Amarillo Grande. To exercise this right, IMSA must incur certain funding obligations over the six-year term of the Call Option, pay the relevant option price pursuant to the formula set out in the Call Option, and grant to MCA a 2% royalty on all Exploration Targets acquired under the Call Option.

Nevgold Corp. (‘NevGold’ or the ‘Company’) (TSXV:NAU,OTC:NAUFF) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce that is has staked an additional 90 claims, approximately 6 square kilometers or 1500 acres, with strong antimony-gold prospectivity at its Limousine Butte Project (the ‘Project’, ‘Limo Butte’) in Nevada. The newly staked ground has the same geological signatures as other antimony-gold targets at the Project.

Aerial Drone Footage of 2025 Drilling & High-Grade Antimony Bullet Zone Discovery (Click Here):

Key Highlights

• Added an additional 90 claims, approximately 6 square kilometers or 1500 acres, with strong antimony-gold prospectivity

• • The new claims encompass remaining surface exposure of a dolomite-over-Pilot Shale thrust block, as well as exposed Pilot Shale on both the west and east of the dolomite thrust; this geological setting is where the 2025 Bullet Zone drilling discovered significant antimony and gold mineralization (See News Release dated December 2, 2025).
  • Exposed outcrop in the new ground has a strong surface expression of gold and antimony mineralization, with rock chips in Pilot Shale up to 1.23 g/t Au and 0.49% Sb, and rock chips in the dolomite thrust up to 8.74 g/t Au and 0.67% Sb.

• • 8.74 g/t Au
  • 0.36% Sb and 0.10 g/t Au
  • 0.24% Sb and 0.42 g/t Au
  • 0.67% Sb*
  • 0.49% Sb*
  • 0.42% Sb*
  • 0.33% Sb and 0.41 g/t Au*
  • 0.10 % Sb and 1.07 g/t Au*
  • 0.36% Sb*
  • 1.23 g/t Au*
  • 0.76 g/t Au*

• 30 holes have been completed in the current 2025-2026 drill program with assays pending

• The Company has completed Phase 1 antimony-gold sampling of the Crushed and Run of Mine (‘ROM’) leach pads from the past-producing Golden Butte pit, which produced over 100,000 ounces of gold in 1989-1990

• • The historic leach pads have material at surface that was previously mined and crushed with strong antimony-gold potential (see Figure 3); the previous Golden Butte operation was solely focused on gold with no focus on antimony
  • Phase I sampling results will be released over the coming weeks

• Antimony is one of the highest priority Critical Minerals due to its strategic importance and military applications; Limo Butte is a brownfield mine site located in the State of Nevada with near-surface, high-grade antimony mineralization 

Limo Butte Planned 2025-2026 Activities / Status Update
NevGold will continue its active exploration program at Limo Butte including:

• Evaluating the historical geological database with focus on gold and antimony (completed);

• Advancing metallurgical testwork (Phase II completed);

• Continuing to drill test gold-antimony targets (ongoing, 30 drillholes completed)

• Sampling the Crushed and ROM leach pads from the past-producing Golden Butte pit to determine the antimony-gold mineralization (Phase I sampling completed, results in the coming weeks);

• Completing initial gold-antimony Mineral Resource Estimate (MRE) (in progress).

Other 2025-2026 Project Updates
Nutmeg Mountain Gold Project (Idaho)

• 2025 Mineral Resource Estimate (‘MRE’) completed September-2025

• Metallurgical testwork continues

• CSAMT Geophysics to start early January; additional data layers will guide 2026 drill targeting for more near-surface gold mineralization and the potential high-grade gold feeder structure

• 2026 Drill Program of ~5,000 meters focused on significantly expanding the 2025 MRE

Zeus Copper Project (Idaho)

• Geophysical Induced Polarization (‘IP’) and Magnetotellurics (‘MT’) program completed in November-2025

• Drill targeting for 2026 field program is in process

NevGold CEO, Brandon Bonifacio, comments: ‘The newly added ground at Limo Butte has the same geological signatures as the other parts of the Project with strong antimony-gold mineralization. The additional claims also extend the expansion potential to +4 kilometers from Resurrection Ridge, which is where we are currently drilling. We have completed 30 drillholes and the Phase I sampling of the historically mined gold leach pads, with results expected over the coming weeks from both of these work programs. As Limo Butte is a brownfield mine site, one key advantage is having a large amount of historically mined material already on surface in the leach pads that had a previous focus only on gold mineralization. The historically mined leach pads are a significant, near-surface antimony opportunity that we are rapidly advancing. We are pleased to enter 2026 with a strong treasury position and the ability to systematically advance our Gold and Critical Minerals assets based in the United States to maximize value for our shareholders.’

US Executive Order – Announced March 20, 2025
The Company is pleased to report the sweeping Executive Order to strengthen American mineral production and reduce U.S. reliance on foreign nations for its mineral supply. Antimony (Sb) has been identified as an important ‘Critical Mineral’ in the United States essential for national security, clean energy, and technology applications, yet limited domestic mine supply currently exists.

The Executive Order invokes the use of the Defense Production Act as part of a broad United States (‘US’) Government effort to expand domestic minerals production on national security grounds. As it relates to project permitting, the Order states that it will ‘identify priority projects that can be immediately approved or for which permits can be immediately issued, and take all necessary or appropriate actions…to expedite and issue the relevant permits or approvals.’ Furthermore, the Order includes provisions to accelerate access to private and public capital for domestic projects, including the creation of a ‘dedicated mineral and mineral production fund for domestic investments’ under the Development Finance Corporation (‘DFC’).

This decisive action by the US Government highlights the urgent need to expand domestic minerals output to support supply chain security in the United States. This important Order will help revitalize domestic mineral production by improving the permitting process and providing financial support to qualifying domestic projects.

Importance of Antimony
Antimony is considered a ‘Critical Mineral’ by the United States based on the U.S. Geological Survey’s 2022 list (U.S.G.S. (2022)). ‘Critical Minerals’ are metals and non-metals essential to the economy and national security. Antimony is utilized in all manners of military applications, including the manufacturing of armor piercing bullets, night vision goggles, infrared sensors, precision optics, laser sighting, explosive formulations, hardened lead for bullets and shrapnel, ammunition primers, tracer ammunition, nuclear weapons and production, tritium production, flares, military clothing, and communication equipment. Other uses include technology (semi-conductors, circuit boards, electric switches, fluorescent lighting, high quality clear glass and lithium-ion batteries) and clean-energy storage.

Globally, approximately 90% of the world’s current antimony supply is produced by China, Russia, and Tajikistan. Beginning on September 15, 2024, China, which is responsible for nearly half of all global mined antimony output and dominates global refinement and processing, announced that it will restrict antimony exports. In December-2024, China explicitly restricted antimony exports to the United States citing its dual military and civilian uses, which further exacerbated global supply chain concerns. (Lv, A. and Munroe, T. (2024)) The U.S. Department of Defense (‘DOD’) has designated antimony as a ‘Critical Mineral’ due to its importance in national security, and governments are now prioritizing domestic production to mitigate supply chain disruptions. Projects exploring antimony sources in North America play a key role in addressing these challenges.

Perpetua Resources Corp. (‘Perpetua’, NASDAQ:PPTA, TSX:PPTA) has the most advanced domestic gold-antimony project in the United States. Perpetua’s project, known as Stibnite, is located in Idaho approximately 130 km northeast of NevGold’s Nutmeg Mountain and Zeus projects. Positive advancements at Stibnite including technical development and permitting has led to US$75 million in Department of Defense (‘DOD’) awards, over $1.8 billion in indicative financing from the Export Import Bank of the United States (‘US EXIM’) (see Perpetua Resources News Release from April 8, 2024) (Perpetua Resources. (2025)), and recent strategic investments of US$180 million from Agnico-Eagle Mines Limited (‘Agnico’) and US$75 million from JPMorganChase’s $1.5 trillion Security and Resiliency Initiative. (see Perpetua Resources News Release from October 27, 2025)

Skyharbour Resources Ltd. (TSX-V: SYH ) (OTCQX: SYHBF ) (Frankfurt: SC1P ) (‘Skyharbour’, ‘SYH’ or the ‘Company’) is pleased to announce the closing of the definitive repurchase agreement (the ‘Strategic Agreement’) with Denison Mines Corp. (‘Denison’ or ‘DML’), whereby Denison has acquired an initial project interest in Skyharbour’s Russell Lake Uranium Project (‘Russell’ or the ‘Project’) and the parties have entered into four separate joint venture agreements 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 exploration camp, 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 payments to Skyharbour totalling $10.0 million, additional consideration of $8.0 million payable in cash and shares before year end, and expenditures and cash payments totalling up to $43.5 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 has been 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 geological teams of Denison and Skyharbour have begun working 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 will 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 is well funded going into 2026 with over $11 million in the treasury. The Company will also generate revenue from its operator fee at the McGowan Lake exploration camp at the Project, as well as from cash and share payments from other option earn-in partner companies.

• 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.

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

Jordan Trimble, President and CEO of Skyharbour, stated: ‘We are thrilled to close this major transaction for Skyharbour, and to embark on the next chapter of exploration at Russell with a multi-billion dollar strategic partner and large shareholder in Denison Mines. With up to $61.5 million in combined project consideration contemplated, we are confident that this strategic agreement will expedite the discovery process at the Project while minimizing equity dilution for our shareholders. Based on initial technical meetings and strategy sessions with Denison, we are excited about the combined exploration options for the near term. Russell is one of the more prospective exploration projects in the Athabasca Basin proximal to existing and developing mines including Denison’s Pheonix deposit at Wheeler River. Denison will also be able to provide considerable insight and experience as we jointly advance Russell. Lastly, we now enter the new year with a healthy treasury of over $11 million to fund our exploration efforts and corporate activities through 2026 while various partner companies fund exploration at numerous other projects in our portfolio.’

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.’

Transaction Details:

The consideration payment consisted of a $10.0 million cash payment, with $2.0 million paid upon execution of the Strategic Agreement and $8.0 million paid upon closing of the Strategic Agreement. An additional $8.0 million is payable in cash and shares by Denison on or before December 31 ^st , 2025 with a minimum of $2.0 million payable in cash.

It is anticipated that Denison will also be making use of the current exploration camp at McGowan Lake on the Project, which 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.

Skyharbour has received conditional approval from the TSX Venture Exchange for closing. The issuance of shares by Denison to Skyharbour remains subject to appliable exchange approvals.

Summary of Initial Joint Ventures:

Upon closing of the Strategic Agreement, Denison has earned 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 claims marked in yellow in the accompanying map 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 claims marked in pink in the accompanying map 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. Skyharbour will remain operator of RL.
3. Wheeler River Inliers (30% SYH, 70% DML) . The claims marked in blue in the accompanying map 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 claim marked in green in the accompanying map 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 remains operator of Getty East; however, Denison has the option to become the operator and acquire up to a 70% interest in this joint venture as described in more detail below.

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.

About Skyharbour Resources Ltd.:

Skyharbour holds an extensive portfolio of uranium exploration projects in Canada’s Athabasca Basin and is well positioned to benefit from improving uranium market fundamentals with interest in thirty-seven projects covering over 616,000 hectares (over 1.5 million acres) of land. 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.
