MINING and power group Hargreaves Services pledged to continue its drive into Europe as it reported six months of surging profits despite low coal prices. The firm, which owns Yorkshire’s Maltby colliery and employs more than 1,000 in the region, is expanding across Europe through its energy and commodities arm, to capitalise on recovering coal demand on the continent. One of the UK’s few remaining operational deep mines, Hargreaves bought Maltby from UK Coal in 2007. It has spent more than £20m on upgrading the mine through new mining and gas capture equipment.
