New Found Gold Corp. has reported the results of the 2023 Phase I Metallurgical Test Program conducted on drill core samples collected as part of the exploration program at its 100% owned Queensway Project (?Queensway?), located on the Trans-Canada Highway 15 km west of Gander, Newfoundland. Highlights: Phase I of metallurgical testing began in 2023 and focused on three mineralized zones ?
Keats Main, Golden Joint and Lotto. A total of 116 variability composites were generated from approximately 1,000 meters of drill core with a combined weight of 3,400 kilograms, from which three main composites were constructed. The weighted average gold extraction on all 116 variability samples, broken down to the five cross sections, ranges from 90% to 96%.
The gold extraction was achieved using both gravity separation and conventional carbon-in-leach (CIL) on the gravity tailings. The gold extraction in the three zones tested in Phase I shows similar metallurgical characteristics and similar extractions were achieved with both gravity and CIL. The company is currently engaged in a Phase II metallurgical testing program focused on Iceberg and Iceberg East. The composites have been selected for shipment to Base Metallurgical Laboratory Ltd. in Kamloops, BC, and testing will begin in the second quarter of 2024.
The metallurgical testing work at Queensway has been designed and supervised by Gary Simmons (MMSA QP Number: 01013QP) as an independent consultant. Mr. Simmons is an internationally recognized metallurgist who previously served as director of metallurgy and technology for Newmont Mining Corporation, where he led the R&D staff of the company’s metallurgical laboratory and a number of process engineers responsible for global process development and design engineering from Newmont. Additional details: The scope of Phase I consisted of chemical and mineralogical analyses, environmental characterization, establishment of milling parameters, gold extraction methods, reagent consumption, cyanide detoxification, and solid-liquid separation properties for process and residue streams. The results, which include all 116 variability composites, indicate that mineralized zones are generally of high quality and contain high amounts of free milled gold, which is suitable for both gravity and CIL caustic extraction.
Free gold grains larger than 150 microns were mainly observed in the quartz veins in the zones. The weighted average gold extraction for all mineralized zones ranged from 90% to 96% when reduced to a product size of 75 microns. Grinding test work indicated that the material tested had an average SMC Axb index of approximately 62 and an average Bond Work Index (BWI) of approximately 17.5 kWh/t, which would be considered a medium hard ore for SAG grinding and medium hard ore for ball grinding.
Laboratory tests were carried out by Base Metallurgical Laboratory Ltd. in Kamloops, British Columbia.
