Recent Metallurgical Advances for Enhanced Gold Recovery
U.S. GoldMining Inc. has made significant progress in its ongoing metallurgical test work for the Whistler Gold-Copper Project, as recent results show a remarkable increase in gold recovery rates. This advancement highlights the effectiveness of the newly implemented leaching processes alongside traditional flotation methods.
Gold and Copper Recovery Highlights
According to the latest findings, the tests have led to a substantial gold recovery rate of up to 85.3%, with corresponding recoveries of 79.1% for copper and 55.3% for silver. These impressive figures were achieved through a combination of sulphide flotation and leaching techniques applied to a master composite derived from the Whistler Deposit's drill core.
Understanding the Test Results
The locked cycle tests performed during the flotation processes resulted in a copper concentrate graded at 23.7% Cu, with initial metal recoveries of 54.1% gold, 79.1% copper, and 55.3% silver. These results are critical as they offer essential inputs for the initial economic assessment of the project.
Commentary from Leadership
Tim Smith, the CEO of U.S. GoldMining, expressed excitement regarding these findings, stating that the recovery improvements from the previous tests—where only sulphide flotation yielded approximately 70%—are a notable success for the company. Highlighting the dual approach of flotation followed by leaching, Smith believes this methodology is crucial for the project's success.
Details of the 2025 Metallurgical Program
The metallurgical program aims to optimize metal recovery from the Whistler deposit's drill core samples. The testing involved a selection of drill core composites that accurately represent the resource’s grade. Through comprehensive analyses, the project team is looking to refine recovery techniques to maximize efficiency.
Flotation and Grinding Process Breakdown
The completed comminution tests classified the master composite as 'Hard' to 'Very Hard', leading to the selection of optimal grind sizes for the flotation tests. The procedure included a primary grind size of 120 µm, followed by a regrind process that aided in achieving higher recovery rates.
Impacts on Future Operations
Upon combining the flotation outcomes with additional leaching techniques, the overall gold recovery has reached an impressive 85.3%. Future evaluations may further enhance recovery strategies as the team examines the potential of bypassing certain steps to simplify processing while still increasing recovery rates.
Exploring the Whistler Project's Potential
The Whistler Gold-Copper Project is positioned within a significant geological region promising rich vein deposits. U.S. GoldMining is dedicated to exploring further opportunities within the project while maximizing the mineral resource potentials discovered through diligent testing. The future of the project looks positive as it continues to evolve through rigorous scientific inquiry and applied techniques.
