Golden Sky Announces Commencement of a Geophysical IP Survey at the Rayfield Copper-Gold Property, South-Central British Columbia - Seite 3

Exploration drilling on the property from the 1970s to the early 2000s totalled just 60 holes (7,774.2 meters), with the majority being shallow percussion holes typically <60 m in depth. Historic drilling outlined a broad footprint (450 m x 2,100 m) of low-grade copper mineralization and hydrothermal alteration indicating potential for a robust copper-gold porphyry system.

• 1970 Exploration Program: 31 percussion holes totalling 1,748 m
  • Drillhole highlights include: 0.42% Cu over 6.1m
• 1989 Exploration Program: 8 diamond drillholes totalling 1,141 m
  • Drillhole highlights include: 0.18% Cu and 71 ppb Au over 33.9 m; 0.14% Cu and 30 ppb Au over 66.7 m
• 1990 Exploration Program: 14 diamond drillholes totalling 3,337 m
  • Drillhole highlights include: 0.13% Cu and 35 ppb Au over 152 m (EOH)
• 2008 Exploration Program: 7 diamond drillholes totalling 1,548.2 m
  • Drillhole highlights include: 0.13% Cu and <10 ppb Au over 67 m
    

Many shallow historical drill intercepts on the Rayfield Property have similar grades to historic holes reported during early exploration phases on some neighboring alkalic copper-gold porphyries within the Quesnel Terrane. Further drilling is warranted to explore zones of mineralization along strike and to depth.

Figure 1: The ~35,000-hectare Rayfield Cu-Au Property is located within the Quesnel Trough, British Columbia’s primary copper-producing belt.

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.

Elevated values in copper also coincide with pathfinder geochemical elements commonly associated with deeper sericitic and/or propylitic alteration, typically bounding the higher-grade core of porphyry systems. See Figure 4 for cross section A-A’.

Figure 4: Cross-section A-A’ outlined in Figure 3. Historical diamond drill results with interpreted potassic zone of the porphyry system flanked by lower-grade copper within propylitic/phyllic zones. Historical induced polarization surveys extend only to ~125m of depth and many of the historical drill holes ended in mineralization. Mineralization is interpreted to remain open along strike and at depth.
