SUMMARY

· TANNENBERG COPPER PROJECT (GERMANY)

o EXPLORATION TARGET:

o Exploration Target announced demonstrates potential for a globally significant copper endowment at Tannenberg.

o Exploration Target captures hanging wall and footwall mineralisation above and below the Kupferschiefer shale: a modern view of the deposit that the 1940 historical estimate did not contemplate.

o Validated by Kupferschiefer mining in Poland, where up to 95% of mineable copper at KGHM Polska Miedź S.A’s operations is hosted in the same footwall sandstone and hanging wall limestone units that host the Tannenberg Exploration Target.

o Built on validated historical foundations: the Exploration Target builds on the 1940 National Socialist historical estimate area; the 1984 St Joe historical estimate; validation via resampling and logging of 1980’s core by GreenX and digitised archive material collected since August 2024.

o An inflection point for Tannenberg: with the Exploration Target estimated, GreenX now transitions from archive synthesis to active exploration, including Scoping Study-level metallurgical test work, a seismic survey and commencement of an initial drill program.

o Work completed by Palsatech in a specialist logging facility in Sweden with MSA Mining Consulting UK Ltd’s independent competent person compiling the Exploration Target.
