Coal mining company Canyon Coal, a Menar group company, is prepared to offer coal to State-owned electricity utility Eskom at a cheaper price on an open-book basis from two new projects. The Menar group, which does not supply coal to Eskom at present, employs 3 500 people on a R7-billion asset base that includes Canyon Coal, Kangra Coal and Zululand Anthracite Colliery (ZAC).
