Today, Outcrop Silver & Gold (OCG.v OCGSF) announced breakthrough results from the initial gravimetric concentration test work as part of the program to enhance its already high recoveries at its 100% owned High-Grade Santa Ana Silver Project in Colombia.
Significantly, this phase of testing has proven the effective recovery of silver and gold from mineralized material through mechanical gravimetric processes before conventional flotation.
The resulting silver and gold gravimetric concentrate yielded 2,883 grams per tonne of silver and 164.12 grams per tonne of gold.
OCG President and CEO, Ian Harris, commented:
"We are thrilled about the latest gravimetric concentration tests having not only achieved concentrate grades well exceeding 150 gold equivalent grams per tonne — a key marker for highly marketable concentrates — but have also demonstrated significant potential for enhancing our overall recovery rates. With a 7% recovery via gravimetric methods complementing our 93% flotation recoveries, and without the use of cyanide, we are setting new benchmarks for economic viability and reducing our environmental footprint in precious metals mining,"
"This positions the Santa Ana project as one of the world's highest-grade primary silver endeavors, promising exceptional recoveries and highly marketable concentrates. We have already initiated the next phase of test work to integrate gravimetric and flotation methods and look forward to sharing these promising results as soon as they are available."
As these results both confirmed the viability of recovering forms of silver through gravity concentration as well as yielded excellent concentrate grades, the combination of high-recovery rates and high-grade concentrates sets Santa Ana apart as a unique project in the mining sector.
Boasting one of the highest-grade undeveloped primary silver projects in the world, OCG's Santa Ana Project in Colombia has a mineral resource of 37 million ounces grading over 600 g/t AgEq and 18 km of untapped veins.
Furthermore, Santa Ana's excellent metallurgy enables multiple production options from concentrate to dor with 93%+ recoveries and without cyanide.
Following a productive year in 2023, OCG is targeting significant expansion at Santa Ana with its 2024 drill program focused on "demonstrating the potential for a larger resource, maintaining a tight environmental footprint, and being prepared to scale up operations if silver prices rise".
Significantly, there is the potential to increase the mineral resource to over 100 million ounces as the current resource is only on 10% of the property with less than 25% of the concession area mapped.
2024 Drill Program Strategy
Aiming to fully unlock the potential of the distinctive high-grade primary silver project, OCG's 2024 drill program is a pivotal initiative that marks the start of a comprehensive exploration effort focused on amplifying mineralization at OCG's existing targets as well as uncovering new prospects within the project's expansive 18.5km area that has drilling permission.
OCG's drill program strategy is designed to underscore the scalability of the project and its significant potential for resource expansion by leveraging their technical expertise and deep understanding of the region's geology to unlock the full value of the high-grade silver project.
