The Groundhog Project is the world’s largest undeveloped anthracite deposit, located in British Columbia, Canada. |
Summary:
Anthracite coal deposits of the Klappan and Groundhog coalfields occur within the Bowser Basin in a remote region of rugged mountainous terrain in northwestern British Columbia. The basin, which encompasses an area of approximately 50,000 square kilometres, is defined by the outcrop extent of up to 3500 metres of sediments of the Bowser Lake Group of Middle Jurassic to Lower Cretaceous age.
The coal is contained in the Jura-Cretaceous Currier Formation which is up to 1100 metres thick and contains up to 25 seams, ranging in thickness up to 7 metres. The area is extensively folded with the regional structure dominated by a northwest trending synclinorium.
Coal in the northern 10 per cent of the Bowser Basin is found in the Upper Jurassic to Lower Cretaceous Currier Formation in the Klappan Coalfield and in its equivalent in the south, the Prudential Formation in the Groundhog Coalfield.
The Bowser sediments are extensively folded with the regional structure which is controlled by a prominent northwest trending synclinorium (the Biernes Synclinorium).
Potentially economic coal seams up to 7 metres thick are present in the lower third of the Currier Formation. In the Mount Klappan area the formation is 900 to 950 metres thick and contains a cumulative coal thickness that ranges up to 54 metres.
Mining Methods
- Continuous
- Bord-and-pillar
Summary:
The preferred location of the bulk sample has been identified on the basis of anthracite quality, structural geology, seam thickness, shallow floor dip, ease of access and high product yield. The mine design and associated mine plan for the bulk sample is complete, utilising a simple bord and pillar mining method accessed through an adit to provide the Company with a low-capital entry to production. It is likely that the adit will double as the access point for the commencement of small scale mining and future commercial production.
