Golden Sky Outlines Major Induced-Polarization (IP) Geophysical Anomaly at the Rayfield Copper- Gold Property, South-Central British Columbia
Golden Sky Outlines Major Induced-Polarization (IP) Geophysical Anomaly at the Rayfield Copper-
Gold Property, South-Central British Columbia
Vancouver, June 6, 2024 – Golden Sky Minerals Corp. ( AUEN.V) (“Golden Sky” or “T he Company”) is
pleased to announce t he results and preliminary interpretations from a ~15-line kilometre induced-
polarization (IP) geophysical survey completed this spring at the Rayfield Zone on its 100%-owned Rayfield
Copper-Gold Property in south-central British Columbia, Canada. The 35,000-hectare Rayfield property is
located in the Quesnel terrane, British Columbia’s primary copper-producing belt, which hosts Teck
Resources’ Highland Valley Mine, Imperial Metals’ Mount Polley Mine, Centerra Gold’s Mount Milligan
Mine, and Kodiak Copper’s MPD Project (Figures 1 & 2). The road-accessible Rayfield copper-gold property
is located approximately 20 kilometers east of the town of 70 Mile House, British Columbia, and is
accessible year-round by well-maintained service and logging roads extending from BC Highway 97.
Results from the IP survey have detected multiple IP chargeability and resistivity geophysical anomalies
over the entire ~1,100 m strike-length of the survey, extending to a depth of ~800 vertical metres below
surface (Figure 1). These anomalies remain open along -strike and to depth. The survey tested only
about 30% of the ~3.0 km x 1.5 km copper -in-soil geochemical anomaly outlined within the Rayfield
Zone. The remaining 70% has yet to be systematically explored, suggesting significant untapped
potential. Historical drilling at the Rayfield zone has been limited and non -systematic, with drill collars
occurring as clusters rather than distributed along-strike. Despite this, many of the historical shallow drill
intercepts at the Rayfield Zone have similar grades to historic holes reported during early exploration
phases on several neighboring alkalic copper-gold porphyry prospects within the Quesnel Terrane. Golden
Sky is well positioned to test the full extent of this large porphyry system.
John Newell, President and CEO of Golden Sky Minerals, states : “We are thrilled to unveil the preliminary
results from the recent induced-polarization geophysical survey at our Rayfield Copper-Gold Property. The
identified anomalies not only underscore the potential scale and richness of this mineral system, but they
also strategically position Golden Sky to unlock the significant value beneath the Rayfield Zone. This survey,
highlighting a notably extensive chargeability and resistivity anomaly, confirms our belief in the Rayfield
property’s potential as a key player in British Columbia’s renowned copper -gold belt. Our next steps will
focus on systematic drilling to thoroughly explore these exciting targets, particularly the promising zones
that remain largely untested during historic endeavors. We are committed to advancing Rayfield with the
same rigor and precision that have defined our operations, aiming to add substantial value for our
shareholders and contribute positively to the local economy. The future at Rayfield looks very promising,
and we are just getting started.”

Interpretation of Data
1. Chargeability & Resistivity Anomaly:
• The ~600 m x ~1 ,100 m moderate chargeability & resistivity anomaly is closely correlated with
gold and copper mineralization, both at surface and within historic drillholes.
• The anomal y’s sub-vertical to steeply northeast -dipping orientation aligns with the observed
surface quartz vein orientations, suggesting a continuity of the mineralized system to a minimum
depth of 800 m (Figures 4 and 5).
2. Historic Drill Log Observations:
• Drill holes intersecting the anomaly show moderate to heavy fracturing with potassic , clay,
epidote and hematite alteration. The overprinted nature of alteration styles suggests multiple
pulses of mineralized fluids occurred in a long-lived porphyry-style system.
• Mineralization is present as primary sulphides (chalcopyrite, bornite, and chalcocite) and as
secondary copper oxides (cuprite and malachite). The primary sulphides are most commonly
occurring as fracture fills and along quartz veinlet margins and occasionally as interstitial
disseminations. Secondary copper oxides tend to be present within fault zones, fractures, clay
gouge, feldspar veinlets margins, and rarely as disseminations replacing mafic minerals. Native
copper is often present with the primary sul phides. The copper grade correlates closely with the
degree of fracturing/quartz veining and provides evidence for higher-grade “cores” at the Rayfield
Zone.

3. Resistivity and Magnetics:
• The moderate chargeability anomaly, associated with moderate to high resistivity features may
indicate the presence of highly veined, fractured, and brecciated zones, which are commonly
enriched in copper and gold.
• The associated magnetic low signature suggests magnetite- destructive alteration, a common
feature in the core of porphyry systems where hydrothermal fluids alter primary magnetite.
Expansion Potential of the Rayfield Zone
The Rayfield Zone exhibits significant potential for expansion based on several key factors:
1. Large Geochemical Anomaly:
• The copper-in-soil geochemical anomaly spans ~3.0 km x 1.5 km, yet only 30% of this area has
been tested by the IP survey. This leaves 70% of the anomaly untested, offering substantial room
for discovery of additional mineralized zones.
2. Open Geophysical Anomalies:
• The detected chargeability and resistivity anomalies extend over an 1 ,100 m strike length and
down to ~800 m depth, with both dimensions remaining open. This suggests that the mineralized
system could extend significantly further along-strike and at depth.
3. Historical Drilling Gaps:
• Historical drilling has been relatively shallow , with a maximum depth of around 300 m, and has
been conducted in clustered locations. This has left much of the chargeability and resistivity
anomalies largely untested along-strike and to depth. This presents an opportunity for systematic
and deeper exploration to fully understand the extent of the mineralization.
• Historical drilling was predominantly vertical, which may have only partially tested the steeply
dipping mineralized zones as there would be a risk of paralleling the higher-grade zones. Inclined
drilling could more effectively test the full potential of these mineralized zones.
4. Comparative Potential:
• Shallow historical drill intercepts in the Rayfield Zone show grades similar to those in the early
exploration phases of neighboring alkalic copper -gold porphyr y systems within the Quesnel
terrane. These neighboring prospects have demonstrated significant mineral resources,
suggesting that the Rayfield Zone could have similar potential.
5. Untested Depths:
• With the deepest anomalies detected to 800 m, and considering that deeper drilling has not yet
been conducted, there is considerable potential for discovering mineralization typical of large
porphyry systems at depth.
6. Expansion to the North:
• The strongest and widest chargeability anomalies detected on the northernmost line (1200N)
remain open to the north, indicating that the mineralized system could extend fa rther in that
direction.
7. Structural Controls:
• Understanding and mapping the structural controls of mineralization, such as the orientation of
mineralized quartz veins and the fracturing patterns, could guide future drilling to target high -
potential zones more effectively.

Figure 2: The Rayfield target zone is defined by a large 3.0 km x 1.5 km multi-element soil geochemical anomaly. The Rayfield
target zone is highly prospective, with anomalous copper-in-soil values grading up to ~0.40%, and rock samples grading up to
0.63% Cu and 245 ppb Au. Numerous other target zones also exist across the extensive 35,000-hectare Rayfield Property.
