Explorer Sun Metals has reported results from its 100% owned 96-sq.-km Stardust project which suggest extensions of the 421 zone along its plunge.
Drill highlights include:
- 26.3 metres of 2.59% copper-equivalent;
- 7.2 metres of 3.29% copper-equivalent; and
- 11 metres of 6% copper-equivalent.
The first two intercepts are interpreted to represent an offset extension of the 421 zone up-dip and to the south and are the southernmost test of this zone to date.
The last intercept suggests a down-dip extension of the 421 zone mineralization.
The high-grade copper-gold mineralization at the 421 zone has now been traced over 325 metres down-dip and remains open. The most recent results also bring 421 closer to the Canyon Creek deposit, suggesting potential future mining synergies.
The Stardust project features a 2,200 metre corridor in a carbonate replacement setting with mineralization in the form of skarns, mantos, chimneys and veins. The 421 and Canyon Creek zones are skarns.
Current Canyon Creek resources stand at 985,000 tonnes grading 2.92% copper-equivalent in the indicated category with additional inferred resources of 2 million tonnes grading 2.65% copper-equivalent in the inferred category.
The zone was discovered in 2018; Sun Metals consolidated its ownership of Stardust to 100% in 2019.
