Ann: Updated Announcement - Maiden JORC Resource at Green River, page-3

For those that can't be bothered comparing the two announcements here are the differences.

2. Clarification on Exploration TargetNew clarifications added in the updated PDF:Explanation that the exploration target was inferred from multiple historical wells and the 3D Geological & Groundwater Flow Models.Further details on how tonnage and grade ranges were determined.Reaffirms that a re-entry of the Mt Fuel-Skyline Geyser well will help validate the target.This section provides compliance with JORC Clause 17, which requires transparency on how exploration targets are estimated.
3. Exploration Target DataAlthough the exploration target figures remain unchanged:Brine Tonnes: 1,200–1,500 MtLithium grade: 100–150 ppmLCE: 623,095–1,185,650 tonnesThe rationale for these figures is expanded in the updated version, e.g.,:Lithium values from Bosydaba #1 well ranged from 86 ppm to 171 ppm.Variables used include formation thickness, specific yield, and brine density.
