Sky Gold Corp Reports On Gold And Multi-Element Results Indicating Large Polymetallic System With Critical Minerals At Evening Star, Nevada

VANCOUVER, BC / ACCESS Newswire / June 3, 2026 / SKY GOLD CORP. ("Sky" or the "Company") (TSX.V:SKYG)(OTC PINK:SRKZF) is pleased to present gold and multi-element assay results from recent rock and vein sampling on its 100%-owned Evening Star Project in Walker Lane Gold Trend, Nevada.

Assay results from surface sampling returned a consistent combination of gold, silver, lead, copper and zinc across multiple prospects on the Property. In addition, surface sampling identified elevated critical minerals of bismuth and gallium associated with the polymetallic mineralization.

Grades returned up to 0.45% Bi and up to 23.6 ppm Ga are spatially associated with high-grade gold-silver and copper veins and fault zones.

Highlights:

• Golden Bomber epithermal vein best results:

  • 14.99 g/t Au, 30.65 g/t Ag, 132 ppm Bi, 1.11 % Cu, 2.31 ppm Ga and 0.21 % Pb from trench along strike of the vein.

  • 4.33 g/t Au, 24 g/t Ag, 70 ppm Bi, 0.44 % Cu, 20.8 ppm Ga and 0.37 % Pb from hanging wall granodiorite in contact with the vein.

• Fault zones on CRD Hill were sampled, with best results:

  • 2.9 g/t Au, 232 g/t Ag, 2831 ppm Bi, 0.32 % Cu, 223 ppm Pb, 0.16 % Zn and 115 ppm Mo over 3.0-meters wide fault zone.

  • 1.87 g/t Au, 498 g/t Ag, 761 ppm Bi, 0.98 % Cu, 3.77 ppm Ga, 447 ppm Pb, 0.13 % Zn and 525 ppm Mo from a grab sample.

• High Life granodiorite surface sampling best results returned 17 to 23 ppm Ga.

• Good Hope fault zone best results returned 14.07 g/t Au, 62 g/t Ag, 149 ppm Bi, 2.86 % Cu, 0.9 % Pb and 0.44 % Zn for a fault zone 2.6 meters wide.

The Company cautions that grab samples are selective by nature and are not necessarily representative of the mineralization hosted on the property. These results are used to identify the presence of mineralization and to prioritize future drilling targets.

Mike England, CEO of Sky Gold Corp, comments: "The widespread polymetallic surface grades suggest a shared single hydrothermal source at Evening Star, which is very exciting. In addition, the discovery of elevated bismuth and gallium associated with multiple mineralized targets demonstrates the presence of strategic critical minerals within the Evening Star mineralizing system."

Critical Minerals Potential:

• Bismuth grades ranging up to 0.45 % Bi were found associated with gold-silver-copper fault zones, quartz veining, and skarn mineralization on the Property. Bismuth is a critical mineral due to its use in defense technologies.

• Consistently elevated gallium grades ranging up to 24 ppm Ga were found in rocks at Golden Bomber, Good Hope, High Life, Gold Bug and CRD Hill. Gallium is used in microchips, semiconductors, smart phones and aerospace solar panels.

• The high bismuth and gallium grades suggest potential for producing strategic critical minerals as a by product.

Bismuth:

Up to 4543 ppm Bi was detected, along with 0.93 g/t Au, 62.8 g/t Ag, 0.13% Cu and 0.16% Pb, in a fault zone with chalcedonic quartz veining at Gold Bug. See Table 1.

2831 ppm Bi, with 2.9 g/t Au, 232 g/t Ag, 0.32% Cu and 0.16% Zn is from a channel sample across a 3-meter-wide fault zone and 3491 ppm Bi with 0.41 g/t Au, 22.8 g/t Ag, 8.64% Cu and 0.86% Zn from another fault zone on CRD Hill. See Table 2.

A grade of 1240 ppm Bi returned for quartz vein breccia from the fault zone at Good Hope. See Table 3.

Gallium:

At Golden Bomber, rocks hosting high-grade gold-silver-lead-copper epithermal quartz veining, contain strong gallium grades, ranging from 20 to 23.6 ppm Ga at the contact with the veining. See Table 4.

At Gold Bug North, the rocks hosting a gold-silver-bismuth-copper-lead-bearing fault zone, assayed 18.7 ppm Ga and 23.0 ppm Ga. See Table 1.

Fault Zones at CRD Hill returned consistently high gallium grades, ranging from 16.5 ppm Ga to 23.75 ppm Ga. See Table 2.

Surface sampling of the granodiorite host rocks at High Life returned 17 to 23 ppm Ga. See Table 5.

Granodiorite hosting the historic Evening Star gold mine, returned 2.93 to 5.96 ppm Ga (see Table 6), and Good Hope, a 500-meter long, up to 3-meter-wide fault zone in granodiorite, returned up to 6.84 ppm Ga along with 5.58 g/t Au, 5.1 g/t Ag and 88 ppm Bi. See Table 3.
