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:

多倫多,安大略省/ACCESSWIRE/2024年9月5日/Lahontan Gold Corp(TSXV:LG)(OTCQB:LGCXF)(「公司」或「Lahontan」)很高興地宣佈了公司在內華達州沃克萊恩金銀礦帶著名的聖達菲礦區26平方公里項目所有四個礦牀的冶金試驗結果。此次測試涉及來自先前Lahontan鑽探的205個材料樣品,代表了礦區內五種主要礦化類型中的一種,這些樣品經過了氰化物(「CN」)搖動分析,以確定樣品中CN可溶性金的量,並進行孕育溶液掠奪(「preg-robbing」)分析,來確定/消除四個礦牀中可能存在的任何潛在問題區域的情況。此次測試由內華達州雷諾的Kappes,Cassiday and Associates(「KCA」)完成,他們是全球冶金和工藝諮詢的領先者。測試的亮點描述如下,並在隨後的表格中描述:

  • 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 mineralization types.

  • Calvada礦牀:CN可溶性金分析顯示,與先前報道的冶金結果相比,黃金回收率存在潛在上漲,其中91.5%的火試金黃金可溶於CN,而當前估計的黃金回收率爲71%(請參閱2024年1月22日Lahontan新聞稿)。計劃進行額外的冶金試驗,包括瓶式滾瓶和柱浸試驗,以跟進CN可溶性分析所顯示的潛力。

  • York礦牀:York樣品也表現出黃金回收潛力,高達91.0%的火試金黃金可溶於CN,平均爲78.4%,而當前估計的黃金回收率爲60%(請參閱2024年1月22日Lahontan新聞稿)。

  • 板岩礦牀:板岩的CN可溶性金分析較先前的測試結果有所提高,平均69.0%的火試金黃金與當前估計的50%黃金回收率相比(請參閱2024年1月22日Lahontan新聞稿)。計劃進行額外的測試以進一步優化回收率。

  • Santa Fe礦牀:採樣重點放在兩種礦化類型上,相對於先前的試驗,CN可溶性黃金含量是適度的。計劃對這兩種礦化類型進行包括礦物學分析在內的進一步試驗工作。

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.

吸金潛力:在205個樣本中,只有3個表現出具有侵蝕性的吸金潛力(Santa Fe礦牀),其中一個顯示了適度的吸金性(Slab礦牀,雖然該樣品具有高度可溶性火試金的氰化物性,但這使得吸金結果值得懷疑)。通過將標準的氰化物搖盪試驗的結果與將浸出溶液和已知量的可溶性黃金混合以進行比較來確定吸金性,這提供了一種半定量的吸金評估,通常稱爲吸金指數(PRI)或吸金百分比。

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."

Kimberly Ann,Lahontan創始人,首席執行官,總統兼董事發表了評論:"公司很高興收到KCA的這些結果,繼續證實了Santa Fe礦項目中氧化金礦化的高潛在回收率。多種礦化類型中沒有發現任何顯著的吸金潛力對未來礦山運營來說是個好兆頭。根據KCA的建議,我們將繼續進行冶金測試,進一步優化處理工藝圖,該工藝圖將用於即將進行的初步經濟評估,以分析恢復Santa Fe金屬生產的經濟潛力。

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.
