NOA Lithium reported successful initial hydraulic testing at its Rio Grande Project in Argentina, with well RT-RG26-PW002 achieving pumping rates of 25 L/s, exceeding the 15 L/s rate assumed in the project's PEA. A 48-hour continuous pumping test is currently underway to further refine the hydrogeological model.
NOA Lithium reported encouraging initial hydraulic testing results from its new well, RT-RG26-PW002, at the Rio Grande Project. The well achieved a recommended operating rate of 20 L/s, which exceeds the 15 L/s rate assumed in the project's Preliminary Economic Assessment.
Astra Exploration has released final Phase III drill assays from its La Manchuria gold-silver project, featuring high-grade intercepts at the Basalto and Eastern Zones. While one deep target missed due to andesite host rock, the company plans a major 10,000 to 20,000 metre drilling campaign starting in November to test five new regional targets.
Fredonia Mining has closed a $11.5 million bought deal financing, exceeding its initial $10 million target. The proceeds are intended for the exploration and advancement of the El Dorado Monserrat gold-silver project in Argentina.
Sendero Resources has re-evaluated 77 historical drill holes at its Peñas Negras copper-gold project in Argentina, applying a consistent copper equivalent (CuEq) methodology. This re-analysis provides a project-wide view of mineralization, which starts near surface and extends to over 350 meters downhole, reinforcing the company's excitement for the project. The company also noted that its drill program is fully funded.
Sendero Resources has rebuilt and re-evaluated the historical drill assay database for its Peñas Negras copper-gold project in Argentina, applying a consistent copper equivalent (CuEq) methodology across 77 historical holes. This re-analysis highlights several significant intercepts, including 24 meters grading 1.53% CuEq within a broader 236-meter interval of 0.57% CuEq in hole PNDH-06. The company notes that mineralization begins near surface and extends to over 350 meters downhole, providing a project-wide view of the historical drilling and reinforcing the project's potential for future exploration.
Argenta Silver reported successful initial flotation testwork at the El Quevar project in Argentina, achieving silver recoveries of up to 96% and high-grade silver concentrates of 14,857 g/t Ag. The tests used a conventional rougher-cleaner flotation flowsheet on representative variability samples from the Yaxtché deposit.
Argenta Silver Corp. reported strong initial metallurgical test results from its El Quevar project in Salta Province, Argentina, achieving up to 96% silver recovery and concentrate grades of 14,857 g/t Ag from cleaner flotation. The testwork, conducted by Blue Coast Research, demonstrated the amenability of the Yaxtché deposit's mineralization to a conventional flotation flowsheet. The company also provided an updated mineral resource estimate for the Yaxtché deposit, including 45.3 million ounces of indicated silver and 4.1 million ounces of inferred silver.
Orvana Minerals Corp. has announced a US$15 million three-tiered exploration program for its Taguas Project in Argentina for FY2027. The program consists of 19,500 metres of total drilling, split between oxide resource infill and deep porphyry copper-gold exploration, alongside expanded geophysical surveys.
