This may help clarify. Following excerpt from the Quarterly Report dated 27th April;
"In the June 2023 Quarter, Greenvale will also present an updated geothermal strategy and appoint engineering consultants who will deliver the Company’s maiden
geothermal feasibility study."
Yesterday's announcement achieves the above and sets a time frame of 12 weeks (end July) for the new Geothermal Project PFS.
The above Quarterly Report also states;
"The Company will provide an update on the timing of the delivery of the (Alpha)
PFS together with the results from Test Program 3 in the June 2023 Quarter."
It wouldn't surprise me to see new information next week to coincide with Gold Coast RRS (GRV presentation Wednesday 17th May)
