We employ a team of specialist geologists and engineers, and independent ‘Competent Persons’ to report formally on the quantity, quality and practical ability to mine the coal – we are working to the JORC code of reporting.
Much of our work to date has included drilling boreholes, onshore and offshore, to recover coal samples from deep underground. Lots of local people have asked us ‘why are you drilling when we already have so much historical data and know that the coal is there?’. The answer is that we have to comply with modern international codes to assess and determine the size of the Coal Resource and Reserves and that requires us to undertake our own research to support what already exists.
We have also collated a significant amount of historical data; this includes plans of all of the local old mine workings and historical borehole data, geophysics survey data completed offshore by the NCB, NIREX and UK oil and gas companies, and contemporaneous accounts from miners who worked in Haig and other local mines. In addition, we have undertaken borehole drilling ourselves, both onshore and offshore, including coal sample analysis, downhole geophysics and geotechnical analysis.
The Cumbrian coalfield contains many coal seams, as shown in the stratigraphic column below.
The main seams which WCM is interested in are the Tenquarters, Bannock Band, Main Band and Sixquarters. Of these the Bannock and Main Band are the thickest at more than 2.5m thick each.
