The Kearney Mine and milling facility is known to have the largest confirmed mineral resource of any North American graphite project, and is one of the largest individual flake graphite deposits outside of China and North Korea. |
Summary:
The Kearney Graphite lies within the Grenville Shield. The Grenville provinece is subdivided into two lithological belts and two structural zones.
The Kearney Graphite Property occurs within the Kiosk Domain of the CGB. The Kiosk Domain is at the same structural level as the Britt and Rosseau Domain, all of which comprise the lower, conforming to the southern termination of the Powassan Batholith. The plutonic bodies consist of meta-diorite, garnet-hornblende meta-monzonite, and meta-quartz-monzonite, and occur within a series of mafic quartzo-feldspathic, semi-pelitic, and pelitic gneisses which contain the graphitic horizons.
Summary:
Anticipated 20-year mine plan based on conventional open pit methods that will consist of drilling, blasting, loading, hauling and pit services on a full time schedule of 16 hours/day x 5 days/week.
