Ore Sorting Test Boosts Grade, Cuts Costs at Grande Portage Resources’ New Amalga Gold Project

“The results really exceeded our expectations, because the sorter machine was able to identify and reject nearly all of the waste rock that was mixed in with the ore,” said Kyle Mehalek, lead mining engineer at Grande Portage Resources.

Grande Portage Resources (TSXV:GPG,OTCQB:GPTRF,FWB:GPB) recently initiated testwork for a sensor-based ore-sorting system, using samples from the New Amalga mine project.

The results, according to lead mining engineer Kyle Mehalek, exceeded expectations.
