Golden Sky Announces Commencement of a Geophysical IP Survey at the Rayfield Copper-Gold Property, South-Central British Columbia - Seite 2

In 2006, the Geological Survey of Canada conducted a geophysical program, which included magnetic and radiometric surveys, over the Rayfield Property. The resulting elevated magnetic and potassic anomalies are largely underexplored and show similar characteristics to those signifying other alkalic copper-gold porphyries in the Quesnel Terrane. Fieldwork by Golden Sky has confirmed a close correlation between the volume of sheeted and stockwork quartz veining and magnetic low features. These magnetic lows are also coincident with elevated values of the pathfinder elements manganese (Mn), zinc (Zn), vanadium (V,) and barium (Ba), which are commonly associated with sericitic/propylitic alteration typically bounding the core of a porphyry system.

Recent fieldwork by Golden Sky has outlined a 3.0 km x 1.5 km copper-in-soil geochemical anomaly that remains open to the northwest and to the southeast (Figure 3). Within this anomaly are several soil samples that assayed up to ~4,000 ppm Cu, and rock samples that assayed up to 6,319 ppm (0.63%) Cu and 245.5 ppb Au (Sample 118884; see Oct 31, 2023 news release).

Historic exploration on the Property has been largely constrained to a ~505-hectare zone hosting an extensive copper-gold porphyry system outlined by soil sampling, historic drilling, and shallow-penetration radiometric and IP geophysical surveying. Mineralization in several historic drillholes extends from surface to end of hole, at approximately 150-300 m of depth, which suggests that the mineralized porphyry system remains open at depth. Previous exploration programs were unable to definitively identify the exact orientation of the porphyry system, but mapping by Golden Sky has confirmed at least two main orientations of mineralized quartz veins in the area. These are a northwest striking, steeply northeast dipping set, and an east-west striking, moderately north-dipping set.

• In 1989, a 34 line-kilometer IP survey on the Rayfield Target zone outlined several chargeability “high” zones, which were subsequently tested by drilling programs in 1989, 1990, and 2008. Importantly, due to the shallow response of the survey (limited to ~125 m depth), these anomalies are interpreted to remain open at depth. Golden Sky believes that, with modern exploration methods, there is significant potential to discover additional mineralized zones at depth (Figure 4).
