Ann: Annual Report to Shareholders, page-7

AM27 sorry but your post is inaccurate. TEG and other JVP are relinquishing the permit on 6/12/22
No extensions . No spends. No worries

This from the Annual report
TP/15 Xanadu Joint Venture
Triangle has a 45% interest the TP/15 Xanadu Joint Venture (operated by Westranch Holdings, a subsidiary of Norwest Energy), which is located in the Perth Basin about 300 kms north of Perth. The permit occupies the three nautical mile wide state territorial waters of Western Australia, adjacent to Port Denison, and covering an area of 645km2.
TP/15 hosts the Xanadu oil discovery. The well was drilled from onshore and deviated out to the Xanadu prospect. It encountered oil in three sandstones, two of which were tight and did not yield oil on test. However, one reservoir showed oil mobility. The well was subsequently plugged and abandoned. Subsequent to the end of the financial year the TP/15 Joint Venture concluded its evaluation of the prospectivity of the permit and has agreed that the remaining potential is low. The future years work program of further seismic acquisition followed by a well could not be commercially justified based on the evaluation. In addition, any activity would be costly to undertake in such an environmentally sensitive area. As a result, the parties have decided to relinquish the Permit at the end of the current permit year (6th December 2022)
