VANCOUVER, British Columbia, June 06, 2024 (GLOBE NEWSWIRE) — Golden Sky Minerals Corp. (AUEN.V) (“Golden Sky” or “The Company”) is pleased to announce the 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 anomaly’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 sulphides. 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 porphyry 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 farther 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.

Figure 4: Vertical section resistivity and chargeability (inverted) plot of 2024 IP survey line 1200N, looking to the northwest. The geophysical anomaly remains largely untested to depth on line 1200N. Elevated resistivity values are interpreted to indicate zones of brecciation and quartz veining as observed in historical core logs and on surface.
Figure 5: Vertical section resistivity (inverted) plot of 2024 IP survey line 700N, looking to the northwest. Elevated resistivity is also interpreted to indicate zones of brecciation and quartz veining as observed in historical drill core. The resistivity anomaly closely correlates with some of the highest copper-in-soil values within the Rayfield Zone (up to 0.3% Cu).
