Sierra Nevada Gold Discovers Polymetallic System at As Safra Project in Saudi Arabia
Sierra Nevada Gold has made a significant discovery at its As Safra project in Saudi Arabia, uncovering a polymetallic system that includes gold, silver, copper, lead, and zinc. This discovery is situated approximately 400 metres south of the Central Copper Zone, and it has shed new light on the mineralisation process at As Safra. According to the findings, the mineralisation at this site was formed through multiple hydrothermal events, rather than a single copper-bearing phase. This is a crucial piece of information, as it suggests that the site has a more complex and potentially more lucrative geological profile than initially thought.
KEY Discovery Details
The discovery was made in a breccia, a type of rock that is formed when fragments of other rocks are cemented together, and it extends from near the surface to a depth of approximately 50 metres. The metal association in this breccia is distinct, and it broadens the exploration model for the site. This, in turn, supports the interpretation that As Safra is home to a large, long-lived mineral system. The fact that the breccia is located near the surface also makes it an attractive target for further exploration and potential mining activities.
The results of the initial drilling campaign validate Sierra's integrated targeting approach, which involves using a combination of geological, geophysical, and geochemical data to identify potential mineral deposits. The best assay results from the reverse circulation holes were impressive, with one interval yielding 11 metres of rock containing 1.15 grams per tonne of gold, 108.7 grams per tonne of silver, 0.21% copper, 4.64% zinc, and 1.88% lead. This interval started at a depth of 49 metres and was part of a broader interval of 17 metres that contained 0.81 grams per tonne of gold, 75.2 grams per tonne of silver, 0.14% copper, 3.08% zinc, and 1.25% lead.
Future Drilling Plans
These results confirm that As Safra has experienced multiple mineralising events, which is consistent with the interpretation of a large magmatic-hydrothermal system. This system is thought to extend beyond the known copper-gold skarn mineralisation, and it has the potential to contain significant quantities of gold, silver, copper, lead, and zinc. The next step for Sierra Nevada Gold will be to conduct follow-up drilling to investigate the geometry and true width of the new breccia. This will be part of an expanded Phase 2 drilling campaign, which will comprise more than 25,000 metres of reverse circulation and diamond drilling.
The goal of this campaign will be to gain a better understanding of the mineral system at As Safra and to identify potential targets for future mining activities. With its polymetallic discovery and large, long-lived mineral system, As Safra is shaping up to be a significant project for Sierra Nevada Gold, and the company is likely to be eager to learn more about its potential. The discovery is also a testament to the company's integrated targeting approach, which has proven to be effective in identifying mineral deposits in this region. As the drilling campaign continues, investors and industry observers will be watching with interest to see what other discoveries Sierra Nevada Gold might make at As Safra.
