Risner: Hermosa is only advanced mine that can supply US battery-grade manganese
“And it's also the only advanced mine development that could produce a battery-grade manganese to provide battery-grade manganese for the emerging U.S. And North American electric vehicle supply chain.”
EV battery makers can completely eliminate cobalt by increasing manganese
“One is you can completely displace the cobalt in the battery by increasing the manganese content.”
Risner: Hermosa is only US mine project producing both zinc and manganese
“We have a world-class zinc deposit and a world-class manganese deposit, so it's the only mine development project in the United States. That would produce two critical minerals designated on the US Geological Survey's critical minerals list, so those being zin…”
Risner: Hermosa mine will require under 600 acres of surface disturbance
“We have devised, ah, Hermosa, or designed Hermosa as an underground operation. We can mine both the manganese and the zinc resource with less than 600 acres of total disturbance, compared to upwards of 10,000 for many other mining projects. And the vast majori…”
