York Potash Mine

York Potash Mine

Sirius Minerals is developing the North Yorkshire Polyhalite Project to extract polyhalite ore from the mineral deposit and to transport the ore for processing and export. The Project includes the mine site development including the mine shafts, a 38km tunnel to the processing facilities located on Teesside and facilities to bulk load the processed materials onto ships. The first phase of tunnelling is the design and build of a section of tunnel south of the Wilton site to the first intermediate site at Lockwood Beck.
