Hercules Metals: Unlocking Copper and Silver's Full Potential

Hercules Metals Corp. (TSX-V: BIG) recently announced impressive metallurgical results from its initial Phase I testing, achieving copper recoveries of 90% and silver recoveries exceeding 80%. These remarkable outcomes have the potential to significantly enhance the economic viability of Hercules' Hercules Property in western Idaho.

Firstly, let's delve into the geology of the Hercules Property. It hosts a replacement-style disseminated silver, lead-zinc-manganese±copper system within a Jurassic-aged volcanic tuff. Modern systematic exploration has identified a porphyry copper target in adjacent andesitic volcanic rocks, with shallow level porphyry-style alteration and a copper-in-soil anomaly extending over 2 kilometers.

Now, back to the metallurgical results. The strong copper recovery of 90% was achieved through conventional flotation, which is a straightforward and cost-effective process. This high-grade concentrate, free of deleterious elements, will attract favorable smelter terms, further reducing production costs. The efficient liberation of silver, achieved through a sulfurous acid leach followed by a cyanide leach, boosted silver recovery to 86% for oxide mineralization and 82% for sulfide mineralization. This two-step process significantly improves upon historical recovery methods by over 20%.

These impressive results have far-reaching implications for Hercules Metals' project economics. The high metallurgical recovery rates will lead to lower processing costs and higher overall project value. The efficient liberation of silver and the clean concentrates with no deleterious elements will boost silver production and generate additional revenue. Furthermore, the underlying porphyry system holds the potential for further enhancing the project's economic outlook.

However, it's important to remember that these are Phase I results, and further optimization and testing are underway. The Company is now focusing on optimizing locked cycle flotation of copper and refining the two-step leaching process for silver. Additionally, they are exploring Cu-Mo separation analysis to maximize resource recovery.

In conclusion, Hercules Metals' strong Phase I metallurgical results have the potential to significantly enhance the economic viability of its Hercules property. With high metallurgical recovery rates for both copper and silver, the Company can expect high-grade concentrates that will attract favorable smelter terms and generate additional revenue. The efficient liberation of silver and the underlying porphyry system further bolster the project's economic outlook. As Hercules Metals continues to optimize its metallurgical processes and test the project's full potential, investors should keep a close eye on this promising opportunity.
