U.S. GoldMining Enhancements in Gold Recovery Results
The exploration and development company, U.S. GoldMining Inc. (NASDAQ: USGO), has made groundbreaking advancements in metallurgical testing for its Whistler Gold-Copper Project. Recently, the Company disclosed remarkable findings from its latest testing program, which significantly boosted gold recovery rates to 85.3%—a notable increase of 22% compared to previous tests.
Key Highlights of Metallurgical Tests
Through this comprehensive metallurgical testing program, several key results emerged:
- Gold recovery rates reached up to 85.3%, with copper and silver recoveries of 79.1% and 55.3%, respectively. This achievement came from concentrated sulphide flotation and leaching test work, utilizing a composite derived from drill cores representing the project's average metal grade.
- The locked cycle tests (LCT) indicated successful production of a copper concentrate, grading 23.7% Cu, with minimal mass pull and effective metal recoveries for gold, copper, and silver.
- A total of 28 flotation tests and four additional leach tests were executed by Base Metallurgical Laboratories, underscoring the thoroughness of the research conducted.
Statements from Leadership on Project Developments
Tim Smith, Chief Executive Officer of U.S. GoldMining, expressed enthusiasm regarding these promising results: "We are thrilled with the latest test results, confirming that we can achieve gold recoveries exceeding 85%. Our earlier efforts solely focused on sulphide flotation, yielding a gold recovery near 70%. By incorporating a sequential leach process alongside conventional flotation, we significantly enhanced our metallurgical recovery at the Whistler Deposit. This tested flowsheet is designed to yield a market-ready copper concentrate and direct gold doré through our leaching process, illustrating our commitment to sophisticated and efficient mining practices."
Detailed Overview of the Testing Program
The metallurgical testing program aimed to optimize metal recovery from a planned drill program at the Whistler Deposit. During this process, fresh drill cores from various quarters of the year were combined to create master composites. These were carefully chosen to be representative of the area's mineral wealth.
In terms of grinding processes, preliminary tests categorized the sample as 'Hard' to 'Very Hard,' which led to the identification of specific grind sizes for both primary and secondary grinding priorities.
Advancing Recovery through Flotation and Leaching
The flotation tests included both rougher and cleaner phases, culminating in locked cycle tests that paved the way for a concentrated copper product from the rougher circuit. Noteworthy recoveries were recorded during both phases, hinting at a robust design for further explorations.
Future Testing and Potential Opportunities
Moving forward, the company plans to conduct additional variability tests to explore recovery potential across diverse rock types within the project area. This iterative process could lead to enhanced strategies for maximizing resource extraction and may bring even better recovery rates in future evaluations.
