Lahontan Gold Corp. has announced the commencement of metallurgical test work at its Santa Fe deposit, targeting improvements in the gold and silver recovery rates from the transition metallurgical domain. This testing initiative aims to enhance project economics significantly.
The current recovery rate for gold from the transition domain stands at 49%, as reported in the preliminary economic assessment (PEA) of the Santa Fe Mine project. The company is exploring advanced methodologies for cyanide leaching to unlock higher recovery potential. Enhancing these rates is crucial, given that a substantial part of the minable gold reserves at Santa Fe is situated within this transition area.
The metallurgical work will involve column leach testing, with results expected to be released later this year. This process will not only provide insights into recovery enhancements but also help define the boundaries of different metallurgical domains within the Santa Fe project.
In addition to the metallurgical tests, Lahontan Gold Corp. plans to continue advancing the Santa Fe Mine project towards production. This includes updating the preliminary economic assessment and initiating drilling at the nearby West Santa Fe project later in 2025. The company aims to optimize both gold and silver recoveries comprehensively.
Based in Canada, Lahontan Gold Corp. focuses on the development of gold and silver properties in Nevada’s Walker Lane region. The Santa Fe Mine has a notable production history between 1988 and 1995, which showcases its potential as a lucrative mining project.
The primary aim of the metallurgical test work is to enhance the cyanide leach gold recoveries for transition material, which currently stands at 49%. Improving recoveries from this domain could significantly boost the project's overall economics.
A higher recovery rate directly correlates with increased gold and silver production, which can enhance the profitability of the Santa Fe Mine project. As significant minable gold ounces lie within the transition domain, optimising recoveries will likely lead to more favourable economic outcomes.
The testing will focus on mixed minor sulfide and oxide mineralisation within the transition metallurgical domain. This blend is critical as it comprises a substantial amount of the resource, making the outcomes of the tests particularly relevant.
Results from the metallurgical tests are anticipated later this year. These findings will be crucial in assessing the efficacy of new heap leaching methods and could significantly influence future project development.
In addition to metallurgical testing, the company is evaluating methodologies to better define metallurgical domain boundaries within the Santa Fe deposit. This approach could lead to more accurate resource estimations and potentially bolster the project's production profile.
The Santa Fe project currently boasts an Indicated Mineral Resource of approximately 1.54 million ounces of gold equivalent, with additional Inferred resources. This strong resource base lays a solid foundation for future exploration and development efforts.
The Santa Fe Mine has a history of substantial production, yielding over 359,000 ounces of gold and 702,000 ounces of silver from 1988 to 1995. This past success not only reflects the viability of the project but also underlines the potential for increased future production.
Lahontan is committed to advancing the Santa Fe Mine towards production, with plans to update the Preliminary Economic Assessment and undertake further drilling at its satellite project, West Santa Fe, throughout 2025. These initiatives indicate a proactive approach to enhancing shareholder value.
