Ann: Natural Hydrogen Business Update - CSIRO, page-34

This excerpt from the above announcement isn't a vested narrative, just a pure, impartial assessment of a potential resource that has zero value ascribed to it.
If it proves to be accurate, it dwarfs the "mammoth" French find.

Buru's prospective 2H White Hydrogen Resources:

In January 2023, 2H Resources received an independent third-party Hydrogen Prospective

Resource estimate from RISC Advisory for its South Australian petroleum exploration licence

application areas which indicated a range of risked prospective hydrogen resources across

the six application areas of between:49 million kilograms (1U) and 1.3 billion kilograms (3U)

with a risked Prospective Best Estimate Resource (2U) of 343 million kilograms.

(Refer ASX announcement 23 January 2023).

These risked prospective resources can be viewed in the

context of the widely accepted target price of $2 per kilogram for alternative methods of

hydrogen production to be competitive with hydrogen generated from fossil fuels.

Prospective Resources relate to the estimated quantities of naturally occurring hydrogen gas

that may potentially be recovered by the application of future development projects to

undiscovered accumulations. These estimates have both an associated risk of discovery and

risk of development. Further exploration and appraisal and evaluation is required to

determine the existence of a significant quantity of potentially moveable naturally occurring

hydrogen gas.
