Lahontan Gold Corp (TSXV: LG | OTCQB: LGCXF) has announced results from metallurgical test work spread across all four deposits at the company’s 26-km2 Santa Fe Mine project located in Nevada’s prolific Walker Lane gold and silver belt.
A total of 205 pulp samples from previous Lahontan drilling representing five of the principal mineralization types present throughout the Santa Fe Mine project area, were subjected to cyanide shake analysis to determine the amount of CN-soluble gold in the samples and pregnant solution robbing (preg-robbing) analysis to identify/eliminate any potential problem areas for pregrobbing in the four deposits.
Kimberly Ann, Lahontan founder, CEO, president, and director commented, “The company is excited to receive these results from KCA which continue to confirm the high potential recoveries from oxide gold mineralization at the Santa Fe Mine Project. The absence of any significant preg-robbing potential across multiple mineralization types bodes well for future mine operations. We will continue met testing based on recommendations from KCA to further optimize the processing flow sheet which will be utilized in our upcoming preliminary economic assessment that will analyze the economic upside of resuming precious metal production at Santa Fe.”
Highlights of the test work include:
- Calvada Deposit: The CN-soluble gold analyses show a potential upside in gold recovery compared to previously reported metallurgical results with 91.5% of the fire-assayed gold to be CN-soluble compared to the currently estimated gold recoveries of 71%. Additional metallurgical test work including bottle-roll and column leach tests are planned to follow up on the potential shown by CN-solubility analyses
- York Deposit: York samples also demonstrated a potential upside in gold recovery, with up to 91.0% of the fire-assayed gold to be CN-soluble and averaging 78.4% compared to the currently estimated gold recoveries of 60%
- Slab Deposit: CN-soluble gold analysis for Slab were elevated compared to previous test work, averaging 69.0% of fire-assayed gold compared to the currently estimated 50% gold recovery. Additional testing is planned to further optimize recoveries
- Santa Fe Deposit: Sampling concentrated on two mineralization types and CN-soluble gold contents were moderate compared to previous test work. Additional test work, including mineralogical analysis, are planned for these two mineralization types
