New Found Gold Corp. (TSX-V: NFG) (NYSE-A: NFGC) is pleased to report results from the 2024 Phase II Metallurgical Testing Program conducted on drill core samples collected from the Iceberg and Iceberg East zones as part of the exploration program at its 100% owned Queensway Project, located on the Trans-Canada Highway 15km west of Gander, Newfoundland.
Highlights:
Ron Hampton, Chief Development Officer of New Found, stated: “The Iceberg and Iceberg East zones have similar geology and mineralization style to the Keats Main zone that was previously reported earlier this year. Results from the Iceberg and Iceberg East zones also indicate excellent gold recoveries from the high-grade materials observed at the Queensway Project. In addition, this test work confirms that the mineralization from Iceberg and Iceberg East can be processed using conventional gravity separation and carbon-in-leach (CIL) technology.”
Additional Details:
The second phase of the metallurgical test work at the Queensway property has been completed. The testing targeted the Iceberg and Iceberg East zones. Due to similarities in the mineralization styles found in both the Iceberg and Iceberg East zones, the sampled drill core material was combined to ensure sufficient material for metallurgical testing. A typical cross section from this phase of metallurgical testing identifies drill core intervals that were selected for sampling is shown in Figure 2, with the location of the 10 sections that extend across Iceberg and Iceberg East being shown in Figure 1.
Approximately 340 metres of drill core with a combined weight of 1,400 kilograms was selected for this phase of test work, comprising 46 Variability Composites, from which one Master Composite was assembled, all of which were tested for gold extraction.
The scope of work consisted of chemical and mineralogical analyses, environmental characterization, establishment of comminution parameters, gold extraction methods, reagent consumption, cyanide detoxification, and solid-liquid separation properties for process and tailings streams. The results of the chemical and mineralogical analyses were very similar to the previous test work completed for Keats Main, Lotto and Golden Joint.
Results indicate that Iceberg and Iceberg East are similar to the other mineralized zones tested in the area, which are generally high-grade, and contain significant free-milling gold which is amenable to both gravity and leach extraction. Free gold grains greater than 150 microns in size were observed predominantly in the quartz veins located throughout these zones. The average gold weighted extraction percentage for Iceberg and Iceberg East was 96.9%. The average gold weighted extraction percentage for adjacent tested mineralized zones, Keats Main, Lotto and Golden Joint, ranged from 90.1% to 96.9%, when reduced to a product size of 75 microns (Table 1). These gold extraction percentages were achieved using gravity separation and conventional carbon-in-leach (CIL) technologies. Lower gold extraction values were realized for individual Variability Composite samples that had gold head assay values of less than 2 grams per tonne.
Lower gold extraction trends were observed in samples containing organic carbon, as well as arsenopyrite and pyrite. Despite the Total Organic Carbon (TOC) of each tested mineralized zone being less than 0.1%, it was confirmed that some of the sampled material was mildly preg-robbing, although easily managed by using CIL for gold extraction on the higher-grade materials. A correlation between tailings gold grade and arsenic content was also observed; with the tail grade increasing as a function of increasing arsenic content.
Comminution test work indicated that the tested material had an average SMC Axb index of approximately 64 and an average Bond Work Index (BWI) of approximately 18.3 kWh/t, which would be considered a medium hard ore for SAG milling and medium hard ore for ball milling.
The Company retained metallurgist Gary Simmons as an independent consultant to design and oversee the metallurgical test work program at Queensway. Mr. Simmons is an internationally recognized metallurgist who previously served as Director of Metallurgy and Technology of Newmont Mining Corporation, where he managed the corporate metallurgical laboratory and R&D staff responsible for global Newmont process development and engineering design projects.
Laboratory test work was carried out by Base Metallurgical Laboratory Ltd. in Kamloops, British Columbia.
