Lahontan Gold Corp (TSXV:LG)(OTCQB:LGCXF) has announced promising results from metallurgical test work across all four deposits at its Santa Fe Mine project in Nevada. The study, conducted by Kappes, Cassiday and Associates, focused on cyanide-soluble gold analysis and preg-robbing potential. Key findings include:
– Calvada Deposit: 91.5% CN-soluble gold, up from 71% previously estimated
– York Deposit: Up to 91.0% CN-soluble gold, averaging 78.4% (previously 60%)

TORONTO, ON / ACCESSWIRE / September 5, 2024 / Lahontan Gold Corp (TSXV:LG)(OTCQB:LGCXF) (the “Company” or “Lahontan“) is pleased to announce 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 (“CN”) 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 preg-robbing in the four deposits. The test work was completed by Kappes, Cassiday and Associates (“KCA”) of Reno, Nevada, a global leader in metallurgical and process consulting. Highlights of the test work are described below and in the subsequent table:
-
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 of71% (please see Lahontan press release dated January 22, 2024). 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 averaging78.4% compared to the currently estimated gold recoveries of60% (please see Lahontan press release dated January 22, 2024). -
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 estimated50% gold recovery (please see Lahontan press release dated January 22, 2024). 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.
Preg Robbing Potential: Only three of 205 samples analyzed exhibited aggressive preg robbing potential (Santa Fe deposit), with one showing moderate preg-robbing (Slab deposit, although this sample maintained high cyanide solubility of fire-assayed gold, which makes the preg-robbing result questionable). Preg-robbing is determined by comparing the results of a standard cyanide shake test with that obtained by spiking the leach solution with a known amount of soluble gold providing a semi-quantitative assessment of preg-robbing, typically referred to as the preg-robbing index (PRI) or preg-robbing percentage.
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.”
A summary table of results of CN-soluble gold analysis from 205 pulp samples taken from all four deposits at the Santa Fe Mine Project is shown above. The samples were selected based upon the desire for additional data for mineralization types that were underrepresented in previous metallurgical test work. CN soluble gold percentage (“%”) is the percent of fire-assayed gold that is soluble with CN.
