Announcements, explained

Each one in plain English, with the numbers worked through for a shareholder.

8 July 2019joint venture update▲ GoodMajor

Mahalo partners agreed an initial development: mostly dual-lateral wells in the northern Castor and Pollux seams, an 80 TJ/d modular plant, a ~65 km pipeline up to 120 TJ/d, and FID in June 2020. Comet expects first gas before end of 2021. This sets a later FID than the earlier Sept 2019 date.

30 May 2019material agreement▲ GoodMajor

Comet Ridge replaces its 2016 APA MOU, now including Vintage. APA will do route planning, surveys and apply for a Pipeline Survey Licence for a Galilee-to-Moranbah pipeline. It is still non-binding, so the open binding transport agreement remains unresolved.
