Rapid Critical Metals (ASX: RCM) | Outstanding Silver Lead & Zinc Flotation Recoveries
Rapid Critical Metals Limited (ASX: RCM) | Metallurgical Testwork Results | Webbs and Consol Silver Projects, New South Wales
In this episode, we break down Rapid Critical Metals Limited's initial flotation testwork results from the Webbs and Consol Silver Projects in New South Wales. Rather than new drilling results, this announcement focuses on metallurgy, specifically how efficiently silver, lead and zinc can be recovered using conventional flotation processing.
Key results from the preliminary bench-scale testwork:
Silver recovery of up to 98.7%
Lead recovery of up to 99.3%
Zinc recovery of up to 93.3%
Silver concentrate grade of up to 2,051 grams per tonne silver from the Consol Fines composite
Six rougher flotation tests were completed across three composite samples: Webbs Master, Consol Master and Consol Fines, at two grind sizes of 125 micrometres and 250 micrometres. The Consol Master composite delivered the strongest overall performance, while finer grinding consistently improved silver and zinc recoveries.
The episode explains what the company has reported and why these results are significant. According to the company, metallurgy is one of the most important technical risks in developing a mining project, and these results demonstrate that the silver, lead and zinc mineralisation at Webbs and Consol responds well to conventional flotation processing. The company says the results provide a strong foundation for cleaner flotation optimisation and flowsheet development.
Important context covered in the episode: these are preliminary cumulative rougher flotation results, not final saleable concentrate grades. Cleaner flotation testwork is still required before the company can define saleable concentrate grades and recoveries.
The company's next stated steps include completing cleaner flotation testwork, optimising grind size, reagent schemes and depressant conditions, improving zinc selectivity in the Consol Fines material, conducting variability testwork across additional composites, and integrating the results into ongoing flowsheet development and study work.
This episode is based entirely on the company's ASX announcement and explains what the company has announced, why it says the results are significant, and the next milestones outlined in the release.
