Sun Silver Hits 84.5% Silver Recovery in 24 Hours at Maverick
Perth – October 14, 2026 -- Sun Silver Limited (ASX: SS1; OTCQX: SSLVF) recovered 84.5% of silver and 83.6% of gold within 24 hours in cyanide leach testwork on its Maverick Silver Project in Nevada, strengthening the case for a tank-leach/CIL processing route alongside heap leach.
Sample 1 test delivers peak recoveries within 48 hours
The top result came from Sample 1 (LT15), run at a P80 53μm grind with 5,000 ppm initial and 2,500 ppm maintained sodium cyanide and no lead nitrate. Head assay recoveries were 84.5% for silver and 83.6% for gold, with peak recoveries indicated between 0 and 48 hours. Most recoverable metal in the test was extracted in the first 24 hours.
Interim solution assays for Sample 1 pointed to higher extraction at 24 and 48 hours than the reported figures, which are calculated from final head assay grades. The company notes that interim extractions are indicative point-in-time calculations, not final recoveries.
