The potential of energy solutions group 92 Resources Corp's (CVE:NYT) Hidden Lake lithium project in Canada continues to become more visible.
The firm reported encouraging results from metallurgical work on the pegmatites from the property.
Several flotations tests have now been completed on the whole rock material, the firm said.
They have returned high grade concentrates of between 6.2% and 6.5% lithium at high overall recovery rates - of between 82% and 85%.
"The metallurgical program has advanced significantly further than we had initially anticipated at this stage," said 92 Resources' president and chief executive Adrian Lamoureux.
"We have now demonstrated the spodumene has low iron, is coarse grained, well liberated, and responds strongly to cost effective beneficiation techniques to produce high-grade concentrate at high-recoveries.
"Further, prior test work indicates lithium extractions for the concentrates at up to 97%."
The company boss added that he looked forward to completing the remaining Phase II DMS (dense media separation) work and evaluating the next steps in the flowsheet development.
92 Resources added that a new mini DMS pilot plant of around 500 kg was currently underway with the objective of producing enough middling material to demonstrate the complete beneficiation flowsheet.
In addition, the deportment of the chemical element tantalum will be tracked throughout the process to determine its potential to be recovered.
