Pinnacle Silver and Gold CEO Robert Archer joined Steve Darling from Proactive to share encouraging results from preliminary metallurgical test work at the company’s high-grade El Potrero gold-silver project in Durango, Mexico. Early testing has demonstrated consistently strong gold recoveries, reaching as high as 96.79% and averaging 95.09%, reinforcing the project’s promising economic potential. Archer explained that three representative samples were collected from the mineralized zone inside the Pinos Cuates underground mine, part of the broader Dos de Mayo low-sulphidation epithermal vein system. These samples — each weighing approximately 25 kg — were submitted to SGS Labs in Durango for a series of scoping-level metallurgical evaluations, including grind calibration, gravity separation, and bottle-roll cyanide leach testing. Initial grind calibration using a ball mill achieved a targeted particle size of 80% passing 53 microns (270 mesh), a benchmark suitable for leach optimization. The subsequent cyanide bottle-roll tests returned excellent gold extraction, with recoveries of 92.81%, 95.68% and 96.79% across the three samples. Silver recovery rates were more variable, ranging between 41.41% and 73.53%, with an average of 54.68%. Archer noted that the lower silver recoveries suggest more complex mineralogy, indicating that extended leach times, finer grinding, and potential adjustments in the processing sequence may be required to unlock greater silver value. Looking forward, Archer said the next phase of metallurgical evaluations will likely combine gravity concentration followed by cyanide leaching of the remaining material, a common flow sheet for high-grade epithermal systems. Optimization studies will also focus on enhancing recoveries for lower-grade material while refining overall processing parameters. #proactiveinvestors #pinnaclesilverandgoldcrp #robertarcher #tsxv #pinn #otc #psgcf #GoldMining #SilverMining #Metallurgy #ElPotrero #PinnacleSilverGold #MiningProjects #ResourceDevelopment #MiningMexico #MiningNews #GoldRecovery
