About Comet Ridge

Comet Ridge Limited (ASX: COI) is a publicly listed Australian energy company focused on the development of natural gas resources for the strained east coast Australian market. The company has tenement interests and a suite of prospective projects in Queensland. Our flagship Mahalo Gas Hub project consists of low cost, sales spec natural gas blocks, close to Gladstone, containing low CO2 Gas Reserves.

Comet Ridge plans to transition its Mahalo Gas Hub assets into meaningful gas supply into the east coast gas market, commencing with Mahalo North and the larger Mahalo Gas Project, in joint venture with Santos QNT Pty Ltd (as the Development Operator). These projects will be further supplemented by planned development of gas resources from Comet Ridge’s other 100% held permits, Mahalo East, Mahalo Far East and the newly awarded Mahalo Far East Extension.
