[{"type":"text","content":" VANCOUVER, British Columbia, Feb. 23, 2023 (GLOBE NEWSWIRE) -- Apollo Silver Corp. (“Apollo” or the “Company”) (TSX.V:APGO, OTCQB:APGOF, Frankfurt:6ZF0) is pleased to report preliminary results for silver recovery via bottle roll testing from its 2022 Metallurgical Test Program (the “2022 Test Program”) for the Waterloo deposit. The 2022 Test Program, which is one component of the 2022 Calico Technical Program, is an initial investigation in the overall metallurgical program for the Calico Silver Project (“Calico” or the “Project”), located in San Bernardino County, California. Up to 61% silver recovery using conventional cyanide leaching (bottle roll testing) for ball mill fine grind material (P80 -45 µm). Recovery of up to 72% achieved using a fluoride-assisted leach. Up to 80% silver recovery from ultra-fine grinding (P100 -25 µm) of the material. High Pressure Grinding Roll (“HPGR”) product (P80 -1.7 mm) showed a 50 to 100% percent increased silver recovery over conventional crushed material (P80 -6.3mm). Silver recoveries are favorable and in line with those of an active operation for a similar style deposit. These results will be incorporated into the ongoing work to update the Waterloo Property 2022 Mineral Resource Estimate (“MRE”)1, which forms part of the Calico Project MRE1. The resource update is expected to be completed as scheduled in early March. “These initial metallurgical test program results from the Waterloo property are positive,” commented Apollo’s President and CEO Tom Peregoodoff. “The results show that mineralization at Waterloo responds well to typical processing and recovery technologies, and they are consistent with recoveries at a currently operating silver mine. These results are being incorporated into the ongoing resource estimation work program which we anticipate will be complete in early March. Final results and reporting for the remaining test work for the program are pending, however we expect these to be available in March.” METALLURGICAL TEST PROGRAM The 2022 Test Program began in early 2022 using 2 tonnes of material acquired from three diamond drill holes completed on the Waterloo property in 2012 by a previous operator (see news release dated May 3, 2022). The three drill holes are geologically and mineralogically representative of the Waterloo deposit and were collected in three separa...
