Ann: In-Depth Review of the Leigh Creek Energy Project PRMS, page-26

I think the main point of the ann is that they want to be sure the market understands the extent of the resource - there is a lot more gas to come with only 31% of the coal resource tested. Good summation of the issues here if posters have not already seen. I am a bit behind with my reading. https://*********.com.au/leigh-creek-energy-reveals-potential-further-gas-reserve-upgrades/

The demonstration was only undertaken on the Telford Basin Main Series formation, which has a JORC-compliant indicated resource of 93 million tonnes of coal.

However, the Leigh Creek Energy Project (LCEP) is estimated to contain a total resource of 301.2Mt of coal within the Telford Upper, Main and Lower formations, of which 186.6Mt (or 62%) relates to indicated resources and 114.6Mt (38%) for inferred resources.

This means there is a further 93.6Mt of indicated resource in the Upper Series and 114.6Mt of inferred resource in the Main and Lower Series that were not subject to the demonstration, where the certified reserves were derived.

“These calculations indicate that there is further scope for the LCEP’s gas reserves to be increased over time, as more exploration drilling and seismic work and production tests are undertaken on the Upper and Lower Series coal formations within the Telford Basin,” the company stated.
