- Strong gold recoveries in Nevada King Gold's (NKGFF, Financial) Phase 2 testing at Atlanta Gold Mine.
- Simplified flowsheet expected to reduce operating and initial capital costs.
- Comprehensive testing program validates processing methods across various lithologies.
Nevada King Gold Corp. (OTCQB: NKGFF) has reported positive results from its Phase 2 metallurgical testing at the Atlanta Gold Mine Project. The testing confirmed the effectiveness of a conventional oxide processing method with a simplified flowsheet. This initiative anticipates reduced operating and initial capital costs by replacing the previous three-stage crushing process with a primary and secondary crusher, and eliminating convey-stack processing.
The Phase 2 program, which evaluated 26 drill core composites, demonstrated robust gold recoveries across key mineralized units. Using fine milling, gold extractions were recorded at 90.1% for non-silicified volcanics, 86.1% for silicified volcanics, and 87.7% for silica breccia. Additionally, column leaching of crushed materials achieved an 83.1% extraction rate for non-silicified volcanics. This program builds on the 22 drill core composites from Phase 1, offering a comprehensive dataset on the various lithologies present in the Atlanta resource.
The revised processing flowsheet supports dual pathways for gold recovery: conventional milling for higher-grade material and run-of-mine (ROM) heap leaching for lower-grade, non-silicified volcanics. Despite the favorable results for gold recovery, the silver extraction rates were lower, with figures of 58.1% for non-silicified volcanics and 28.2% for silicified volcanics.
The outcomes from Phase 2 not only reaffirm the Phase 1 results but also enhance the understanding of the metallurgical characteristics of the Atlanta resource. These findings continue to de-risk the Atlanta Gold Mine project, supporting its potential advancement and development.
