RE: RE: Grafoid Grafoid's graphite to graphene transformation process is "agnotistic" - meaning they can source their graphite from most high-grade deposits.
The advantage in using Lac Knife's graphite is that with an grade average 16%, Grafoid can process the ore more economically than a 10% grade. Lac Knife's ore has another cost-mitigating feature: its highly ordered structure. The layered construct adds to the ease of processing.
Bottom line: other sources are available to them.
