Provides Update on Searchlight Minerals Clarkdale Slag ProjectSearchlight Minerals Corp. announced that this project update summarizes the results of the most recent testing of Searchlight Minerals (SRCH) Clarkdale Project located in Clarkdale, AZ. Searchlight Minerals is focused on developing and implementing a cost-effective process to recover the gold and other valuable metals contained in the copper smelter slag left there from the operation of the Clarkdale copper smelter which operated from 1915 to 1954. The smelter operation resulted in a +20 million ton waste product slag pile containing gold, silver, iron, and zinc. Searchlights designated process testing and design company, Arrakis Inc. and others have demonstrated the presence of gold in significant quantities and the ability to recover the gold by different commercial processes with variation in recoverable gold grades. The variability reported to date has been in large part a result of the different parties performing the tests and resulting different testing and analytical methods. Early drilling and analytical work completed by third party reputable companies in 2005 based on 18 drill holes concluded that the pile contained the following quantities of metal. Analysis and testing by Arrakis and others since this estimate was completed have validated the data contained in this chart. The foremost technical issue delaying moving this project to production has been how to accurately analyze the raw slag and how to recover the gold on a consistent basis. While the raw slag remains difficult to accurately analyze via fire assay due to the refractory nature of the slag, all of the processes tested yield gold dorê beads on the process products allowing back calculated recovered gold grades. Four processes have been evaluated in detail at bench and small pilot scale with the following results: Pressure oxidation via autoclave – Oxidizes the slag under elevated pressure and temperature so that it may be subsequently recovered from solution by leaching – High capital and operating cost, moderate gold recovery. Does not recover iron and zinc. 0.25 – 0.35 opt (8.57 – 12.00 gmt) gold recovered. This technology currently used by Barrick and Newmont in Nevada. Pressure leaching via autoclave – Directly dissolves the gold into solution for subsequent recovery. Highest capital and operating cost, but high gold recovery. Does not recover iron and zinc. 0.35 – 0.45 opt (12.00 – 15.43 gmt) gold recovered. High Temperature Melting followed by pressure oxidation leaching via autoclave – Highest capital and operating cost but recovers iron and zinc to pay for higher operating cost. Also has moderate to high gold recovery. 0.25 – 0.45 opt (8.57 – 15.43 gmt) gold recovered. High Temperature Melting followed by fine grinding and cyanide leaching – Lowest capital and operating cost. Moderate gold recovery, but also recovers iron and zinc. 0.25 – 0.30 opt (8.57 – 10.29 gmt) gold recovered. Due to significant increases in the price of pig iron and zinc oxide, this most recent testing effort focused on option (c) and (d) with tests conducted at both the bench and pilot scale on Chain-of-Custody samples taken in December 2020 from the slag pile at Clarkdale. The samples were shipped to and received by Metcovery II in Menomonee Falls (a suburb of Milwaukee, WI). Subsequently a subset of the samples was heated to high temperature resulting in a 'glass' product containing the gold, a metal pig iron bar, and zinc oxide collected from the baghouse/air filter system. The produced products were then shipped to Arrakis Inc. in Englewood, CO where they were opened and processed under the observation of a PhD Metallurgical Engineering candidate at the Colorado School of Mines under the supervision of Dr. Yeonuk Choi at Queens University (formerly at Barrick gold as Director of Technology) in Toronto. Samples taken under Dr. Choi's direction were subsequently shipped COC to AuTec laboratory in Canada for independent third-party analysis. The summary result of this testing in March 2021 was a back calculated head ore grade by analysis by Arrakis of 0.49 opt gold (16.80 gmt) and 0.12 – 1.64 opt gold (4.11 – 56.23 gmt) by AuTec. The problem with this testing was inconsistent recovery of the gold with some of the gold reporting to the glass (which is desired) and some reporting to the iron (which is not desired) although the gold in iron could be recovered by other methods. A subset of 3 of the Metcovery melts of the iron fire assayed with 7 replicates each, indicated an average grade of 0.728 opt Au (24.96 gmt) contained in the raw slag with an average grade of 2.183 opt Au (74.84 gmt) contained in the iron. The most recent repeat testing at Metcovery in January 2022 was conducted in an attempt to move all of the gold into the glass thereby making it available for direct recovery by leaching while maintaining the recovery of pig iron. In seven separate melt tests the back calculated head grade of the raw slag ranged from 0.018 opt Au (0.62 gmt) to 0.187 opt Au (6.44 gmt) (with an average of 0.123 opt Au (4.24 gmt). As a point of reference, Barrick annual report 2nd Qtr. 2022 quotes an average grade processed in their autoclaves in Nevada at 0.065 opt Au (2.24 gmt). Unfortunately, in these tests most of the gold still remained in the iron. The variation of gold grade in these tests is believed to be caused by a difference in operating conditions at Metcovery which Arrakis was not able to control due to constraints imposed by the geometry of the existing Metcovery equipment. However, the gold can be recovered by various methods from the iron and Arrakis has done this on a single bench test only.最新情報をもっと見るRecent updatesお知らせ • Sep 24Searchlight Minerals Corp.
