Challenger Gold (ASX: CEL) (“CEL” the “Company”) reports ongoing metallurgical testwork investigating a potential low-grade zinc concentrate pathway. This program was undertaken to evaluate one of the several clear and material opportunities for improvement of the Hualilan Scoping Study, for inclusion in the Pre-Feasibility Study. Highlights Metallurgical testwork has shown zinc (“Zn”) at head grades as low as 0.4% Zn can be economically recovered compared with the 1.5% Zn cut-off grade used in the Scoping Study (“SS”)Potentially unlocks 211.5 kt of Zn1 in the Hualilan Mineral Resource Estimate (above 0.4% Zn cut-off) compared with the 62 kt Zn produced in the Scoping Study mine plan2The testwork produced a Zn 55% concentrate grade compared to 50% Zn concentrate2 grade in previous testwork, which will provide a significant boost to Zn payabilityTestwork produced a simplified flowsheet with lower reagent consumption, potentially reducing operating costsIn addition to Zn recovery, and higher Zn concentrate…
