Redmoor- Significant Increase in Tungsten Recovery
Strategic Minerals PLC has announced significant improvements in tungsten recovery at its Redmoor Tungsten-Tin-Copper Project, with overall WO3 recovery increasing by a relative 19.2% to 85.8%, a substantial uplift from the previous 72.0%. The company also confirmed silver recoverability, achieving 58.7% recovery to copper concentrate at a grade of 270g/t, which will be incorporated as a smelter credit. While tin and copper recoveries remain largely unchanged at 67.2% and 82.4% respectively, pathways for future improvements have been identified. These enhanced recovery rates are expected to positively impact the upcoming Redmoor Mineral Resource Estimate update and economic sensitivity assessment. Disclaimer*

Recoveries for tin and copper remain broadly unchanged, although the metallurgical report identifies pathways for further improvements in future studies.\n \nHighlights\n· Results demonstrate an increase in WO3 recovery from 72.0% to 85.8%, representing a 19.2% relative uplift in overall WO3 recoverability.\n· With tungsten being the primary economic driver at Redmoor, this increase in tungsten recovery is expected to contribute positively to the new MRE and updated economic sensitivity assessment.\n· Recovery of silver has been confirmed, with 58.7% recovery to copper concentrate at a grade of 270g/t.\n· Silver will be incorporated as a smelter credit on the copper concentrate, and therefore contribute to the updated economic sensitivity assessment.\n· The combined gravity concentrate resulted in an 85.8% recovery of WO3 and a 67.2% recovery of tin. The resultant upgrade from feed is 22.5x and 15.8x for WO3 and tin respectively.\n· Tin and copper recoveries of 67.2% and 82.4% respectively, remain broadly unchang...
