GOLDEN SKY MINERALS FILES NI 43-101 TECHNICAL REPORT ON RAYFIELD COPPER-GOLD PROJECT SUPPORTING 2026 PARTNER-FUNDED DRILL PROGRAM WITH BOLIDEN

Golden Sky Minerals Corp. has filed a National Instrument 43-101, Standards of Disclosure for Mineral Projects, technical report for its Rayfield copper-gold project, located in south-central British Columbia.

The technical report integrates historical exploration results with those from the company's 2025 ZTEM and aeromagnetic surveys and 2026 airborne magnetic program, outlining multiple porphyry copper-gold and epithermal targets across the district-scale property. The report also provides recommendations for a phased exploration program, including target refinement and an initial diamond drilling campaign. The technical report was prepared in accordance with the company's option and joint venture agreement with Boliden Mineral Canada Ltd., a wholly owned subsidiary of Boliden, under which Boliden may earn up to an 80-per-cent interest in the combined Rayfield-Gjoll property by financing up to $20-million in staged exploration expenditures. The technical report establishes a consolidated technical framework for prioritizing targets, advancing toward a partner-financed drilling program in 2026.

The Rayfield copper-gold project comprises a large, district-scale land package within the Quesnel terrane and hosts multiple target zones defined by coincident geological, geochemical and geophysical signatures consistent with alkalic porphyry systems.

The technical report outlines five distinct copper-gold target zones across the property, each supported by multiple independent lines of evidence.

At the Rayfield zone, historical drilling has outlined an extensive mineralized system with an anomalous copper-in-soil geochemical signature measuring approximately 3,000 metres (m) by 1,500 m. Bedrock mineralization is confirmed by historic drilling, including intercepts of 0.19 per cent copper (Cu) over 30 m and 0.18 per cent Cu over 43.4 m. Recent airborne magnetic data have identified multiple corridors having magnetic low signatures coincident with potassic and propylitic alteration and elevated Cu values of up to 0.96 per cent from surface rock sampling. Induced polarization (IP) anomalies defined by a 2024 IP survey remain open at depth, indicating potential for a more robust mineralized core.

The Gnome target is characterized by a large multielement soil geochemical anomaly measuring approximately 1,800 m by 1,500 m, associated with widespread phyllic and propylitic alteration and including polymetallic quartz-carbonate veining. Results from the 2025 ZTEM survey have delineated a prominent resistive body at depth, interpreted as a silicified porphyry core. Historical drilling intersected mineralized monzonitic dikes, potentially the causative intrusions for copper-gold mineralization. Drill hole 72455 intersected 0.10 per cent Cu over the last 68 metres, suggesting that previous drilling may have tested only the outer margins of a larger system. Surface sampling has also returned elevated Cu, gold (Au) and silver (Ag) values, further supporting potential for a buried porphyry system.

At the Semlin target, exploration has defined a 1,700 m by 900 m multielement geochemical soil anomaly coincident with intrusive rocks and sulphide mineralization. Geological mapping has confirmed the presence of a monzonitic to dioritic dike in contact with Nicola Group volcanics, which host disseminated pyrite. Rock sampling has returned strongly elevated values, including 0.20 per cent Cu and elevated molybdenum, and geophysical data indicates proximity to a large resistive intrusive complex. The target remains largely underexplored due to overburden cover.

In the southern portion of the property, including the Mowich target, high-grade copper values of up to 37.45 per cent Cu, 286 grams per tonne (g/t) Au and 200 g/t Ag were returned from rock float samples. While these values are from transported material, they highlight the potential for nearby bedrock mineralization. Airborne magnetic data have identified multiple large magnetic features that are interpreted as intrusive complexes that are spatially associated with northwest-trending structural corridors which are interpreted to control mineralization across the region.

Additional early-stage targets, including the X zone, exhibit coincident geophysical anomalies and favourable geological settings, further supporting the district-scale potential of the project.

Since 2021, Golden Sky has systematically advanced its now, more than 90,000-hectare district-scale Rayfield-Gjoll copper-gold position in the Quesnel trough through multiple phases of geochemical, geophysical and airborne surveys, while expanding its portfolio into Yukon's White Gold district and Ontario's Timmins camp. The company has also secured a $20-million earn-in partnership with Boliden, on the Rayfield-Gjoll project. Readers can find the original news release announcing the agreement. The filing of this technical report represents a key technical milestone and provides a clear framework for prioritizing targets ahead of planned partner-financed drilling in 2026. Golden Sky's strategy remains focused on advancing high-potential assets through strategic partnerships to reduce capital requirements while retaining exposure to exploration success. Golden Sky continues to advance its broader portfolio, subject to results, market conditions and the availability of financing.

John Newell, president and chief executive officer of Golden Sky Minerals, states: "Filing this technical report is an important milestone for Golden Sky and reflects our commitment to advancing the Rayfield-Gjoll project in partnership with Boliden. It provides a transparent technical framework for the Rayfield-Gjoll project that investors and our partner can reference as we advance exploration in 2026. Rayfield is not a single-target story; with five well-defined copper-gold zones, modern geophysical targets that remain open at depth and a disciplined staged work plan, we are well positioned to systematically advance the highest-priority targets alongside Boliden in 2026. This report provides the technical road map for what we expect to be an active and productive exploration season, including partner-funded drilling under our agreement with Boliden."

The technical report, titled "NI 43-101 Technical Report on the Rayfield Copper-Gold Project, British Columbia," with an effective date of March 19, 2026, was prepared by Andy Randell, PGeo (non-independent). The report is available under the company's profile on SEDAR+ and on the company's website.
