NEW FOUND REPORTS POSITIVE PHASE II METALLURGICAL TEST RESULTS DEMONSTRATING 97% GOLD EXTRACTION AT ICEBERG AND ICEBERG EAST
Rhea-AI Summary
New Found Gold Corp (NYSE-A: NFGC) has reported positive Phase II metallurgical test results from its Queensway Project's Iceberg and Iceberg East zones. The testing, conducted on 46 Variability Composites from 340 metres of drill core, demonstrated an average 96.9% gold extraction rate using gravity separation and conventional carbon-in-leach (CIL) technology. These results align with earlier Phase I testing at Keats Main, Golden Joint, and Lotto zones, which showed extraction rates between 90.1% and 96.7%. The company is now conducting additional testing at Keats West, with results expected in Q2 2025.
Positive
- Achieved high gold extraction rate of 96.9% at Iceberg and Iceberg East zones
- Successfully demonstrated compatibility with conventional processing methods
- Consistent results with previous testing phases, indicating reliable extraction potential across zones
Negative
- Lower gold extraction observed in samples containing organic carbon, arsenopyrite and pyrite
- Reduced extraction efficiency in samples with gold content below 2 grams per tonne
- Medium hard ore characteristics requiring significant energy input for processing
News Market Reaction 1 Alert
On the day this news was published, NFGC declined 0.44%, reflecting a mild negative market reaction.
Data tracked by StockTitan Argus on the day of publication.
Highlights:
- Phase II metallurgical testing commenced in 2024, focused on Iceberg and Iceberg East. A total of 46 Variability Composites were generated from approximately 340 metres of drill core with a combined weight of 1,400 kilograms, from which one Master Composite was assembled.
- Weighted average gold extraction from all 46 Variability Composite samples broken out by the 10 cross section lines, shown below on the plan map in Figure 1, averaged
96.9% . Gold extractions were achieved using both gravity separation and conventional carbon-in-leach (CIL) on the gravity tails. - These results compare well with the Phase I metallurgical test results which showed the weighted average gold extraction ranging from
90.1% to96.7% for Keats Main, Golden Joint and Lotto (released April 3, 2024). - The Company is currently undertaking additional metallurgical testing focused on Keats West with composites having been selected and shipped to Base Metallurgical Laboratory Ltd and results anticipated in Q2 2025.

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
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
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.
