Results Add To PEA Studies
Probe Metals Inc.(TSXV: PRB) has obtained positive results from its 2020 metallurgical test work programme on its Val-d’Or East Project in Quebec, Canada.
The programme consisted of mineralogy, physical property characterisation, gravity, cyanidation and flotation tests.
The main objective of the programme was to assess gold recoveries by deposit and/or gold trend and to support the selection and design of the flowsheet for the Preliminary Economic Assessment (PEA).
President and CEO, David Palmer, said the results indicate that all deposits and gold trends are behaving similarly and that they can be treated in a single processing facility. They also indicate that gravity recoverable gold is high in all deposits (above 50% up to 72%) and that the overall gold recovery (gravity + leaching of gravity tails) is above 95% in all cases with the exception of Highway at 91%, which represents only 3% of the 2019 resource estimate.
Mr Palmer said it was demonstrated that the leach gold recoveries can be correlated to head grade and a net gold recovery equation for use in the PEA was established which includes typical plant losses. In addition, the program has demonstrated that all deposits/gold trends are responding very well to other pre-concentration methods like flotation, continuous gravity separation and ore sorting which provides additional opportunities to enhance project value.
The test work programme was performed at Corem facilities in Quebec City.
“The metallurgical test work demonstrates once again how the Val-d’Or East project performs beyond expectations and confirms that it is an excellent candidate for development,” Mr Palmer said.
“We have already shown the area’s ability to host ounces and now we are building confidence in the development potential of those ounces. We have hit a number of key milestones as we advance the project towards the PEA, which includes strong geotechnical results demonstrating good rock stability; favourable environmental characteristics of host rocks; and now confirmation that all of the mineralised materials not only have high gravity and overall recoveries, but all can be processed together in one mill.
“These characteristics will provide initial cost savings during construction as well as adding further value downstream during a production scenario.”
