[{"type":"text","content":"Lahontan Reports CN-Soluble Gold up to 91.5% at Calvada, 91.0% at York and 86.7% at Slab; Preg Robbing Potential Very LowTORONTO, 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 of 71% (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 averaging 78.4% compared to the currently estimated gold recoveries of 60% (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 estimated 50% 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 min...
