The Kearney Mine was first constructed in 1989 and remained operational through 1994, during which time it achieved a peak sustained production rate of 10,000 tons per annum of flake graphite product. The Mine has been under careful stewardship and maintenance since its closure.
Under new ownership and management, the Mine is now undergoing a re-engineering. Re-commissioning process is slated to production as soon as final funding is obtained. |

Ontario Graphite Ltd. (OGL) was the owner of the Kearney mine.
On February 12, 2020, upon application by the secured creditor Orionis Corporation, the Ontario Superior Court of Justice issued an order commencing the CCAA Proceedings for the purpose of initiating a courtsupervised sale and investment solicitation procedure with respect to the assets, undertakings and property of OGL.
February 24, 2022 - approving the Share Purchase Agreement (SPA) between OGL and G6 Energy Corp., as assignee of Bold Global Advisory Ltd.
April 25, 2022 - The transaction contemplated by the SPA closed: 1) all right, title and interest in and to the New OGL Shares and the Post Consolidation OGL Shares were transferred to and vested in G6 Energy Corp., as assignee of Bold Global Advisory Ltd. under the SPA; 2) the majority of OGL’s liabilities were vested out into a newly incorporated entity 1000063081 Ontario Inc. (“ExcludedCo”). ExcludedCo is now the respondent in these CCAA Proceedings.

Summary:
The Mine lies within the Central Gneiss Belt (CGB) of the Grenville Province. The Grenville Province extends from Lake Huron, to the west, through Quebec and Labrador, to the east, and south into New York State. The Grenville Province in Ontario has been sub-divided into two general lithologic zones and two structural zones. These are the CGB, the Central Metasedimentary Belt (CMB), the Grenville Tectonic Zone and the CMB Tectonic Zone, respectively.
The Mine lies within the domain of the CGB. This particular domain lies within the lower thrust sheet of the CGB. Structural trends within this domain swing from east-northeast to southwest as they encounter the southern termination of the Powassan Batholith. Peltic gneisses, which host the graphitic horizons, have been traced west of Highway 11 through Algonquin Provincial Park.
High grade metamorphosed quartz-feldspar-biotite-garnet gneisses are the primary rock types in the vicinity of the graphite horizons. The lithologic unit trends tend to strike north at 20º and dip to the east at 30º to 60º.
In the McGuire West portion of the Mine, where the Open Pit is located, the graphite horizon outcrops over a width of up to 200 m and extends over a strike length of 400 m from Minnow Lake to McGuire Lake. Exploration has indicated that there are two distinct graphite horizons separated vertically by a unit differing in composition from the hanging wall and footwall gneisses. The graphitic mineraliza ........
Summary:
Ore (graphite-rich rock) is extracted via surface excavation and trucked to the nearby mill for processing. This stage of the process also produces waste rock, which is deposited in a designated area within the boundaries of the Kearney Mine property.
Processing
- Crush & Screen plant
- Flotation
- Dewatering

Summary:
Ore is crushed to the consistency of sand and undergoes a series of flotation processes during which graphite flakes are skimmed off. These flakes are then dried and bagged for sale.
The crushed rocks that remain after the graphite is removed, called tailings, are chemically inert and transferred to the on-site tailings area for long-term storage in accordance with Ontario Ministry of Energy requirements and world-class environmental practices.
