Golden Sky Minerals Files NI 43-101 Technical Report on Rayfield Copper-Gold Project

Supporting 2026 Partner-Funded Drill Program with Boliden

Vancouver, March 30, 2026 – Golden Sky Minerals Corp. ( TSX-V: AUEN.V) (“Golden Sky” or the

“Company”) is pleased to announce that it has filed a National Instrument 43 -101 – Standards of

Disclosure for Mineral Projects (“NI 43-101”) Technical Report (the “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% interest in the combined Rayfield -Gjoll Property by funding up to C$20 million in staged

exploration expenditures. The Technical Report establishes a consolidated technical framework for

prioritizing targets, advancing toward a partner-funded 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 m x 1,500 m. Bedrock mineralization

is confirmed by historic drilling , including intercepts of 0.1 9% copper (Cu) over 30 m and 0.18% Cu over

43.4 m. Recent airborne magnetic data has identified multiple corridors having magnetic low signatures

coincident with potassic and propylitic alteration and elevated Cu values of up to 0.96% 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 multi- element soil geochemical anomaly measuring

approximately 1,800 m x 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% 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 x 900 m multi-element 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 0.2 0% 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% Cu, 286 g/t Au, 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 has identified multiple large magnetic features that are interpreted as intrusive complexes that are

spatially associated with northwest -trending structural corridors which are interpreted to contro l

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 d istrict and

Ontario's Timmins camp. The Company has also secured a C$20 million earn-in partnership with Boliden,

on the Rayfield-Gjoll Project. Readers can find the original news release announcing the agreement here.

The filing of this Technical Report represents a key technical milestone and provides a clear framework

for prioritizing targets ahead of planned partner- funded 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 CEO 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 roadmap 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, P.Geo. (non -
