Leigh Creek Energy Limited, formerly Marathon Resources Limited, is an Australia-based gas company. The Company is engaged in mineral, energy and coal exploration. The Company is focused on the development of its Leigh Creek Energy Project (LCEP), which is located within PEL 650 at Leigh Creek in central South Australia. The LCEP seeks to produce pipeline gas and other valuable by-products through the in situ gasification (ISG) of Leigh Creek coal. The LCEP also seeks to extract the energy in coal through ISG methods to produce methane for sale into the nearby eastern Australian gas pipeline network. The LCEP will also utilize waste gases through an adjacent fertilizer plant to provide supply to farmers across South Australia who are reliant on imports. The Company also holds various exploration license applications (mining and petroleum), where all of these tenements are at an early stage of evaluation.
