More finds of potash at third site

MORE potash is being uncovered under the Yorkshire Coast as plans to build a mine near Scarborough advance.

York Potash, the company behind the proposals, has announced further potash finds from its third temporary drilling site.

Previous test drilling has uncovered thicker than expected seams of potash.

Preliminary results from its temporary site at Raikes Lane, south of Sneatonthorpe, indicate a 22 metre thick seam of high grade polyhalite.

Graham Clarke, operations director of Sirius Minerals Plc, the parent company of York Potash, said: “This is another pleasing result for the project and continues our good progress to date.

“We look forward to completing further drilling sites as quickly as possible and advancing the detailed proposals for the mine.”

Polyhalite, which is being uncovered in the area, is processed to create a high-value fertiliser and is the main target of York Potash’s current drilling.

The company is carrying out the exploration programme to define a potash resource and eventually help determine where the mine head will be placed.

The high grade material unearthed at the third site was found between 1,498 metres and 1,521 metres below surface and the mineral cores extracted haven now been sent to the British Geological Survey for detailed analysis.

York Potash will now conduct a ‘deflection’ at the Raikes Lane site, where a second core is extracted at an angle from the original hole.

Bosses hope this deflection could help to further define the extent of the potash deposits.

When the deflection work is finished, the rig will travel to the company’s fourth site at the layby south of the Flask Inn to complete that temporary borehole.

A new coring rig which is currently stored at that site is undergoing final testing and assembly before being moved to the site at Newton House Forestry plantation.

Two weeks ago York Potash confirmed analysed results from the second site, south of Ugglebarnby, which revealed two seams more than 1,400 metres below the surface; one measuring 32.6 metres of high grade potash and the other consisting of 34.3 metres thickness.
