this campaign marks a major milestone for the Company, as it will provide essential data to support

the Preliminary Economic Assessment (PEA), which we expect to award in the near term. This work

will be key in advancing an objective valuation of Rio Grande’s development potential.”

The Rio Grande Project is NOA's flagship asset, with a resource of approximately 4.7 million tons of

lithium carbonate equivalent (LCE) at an average lithium concentration of 525 milligrams per litre. In

December 2024, NOA completed final property payments on its Rio Grande Project, securing 100%

ownership of all claims within this project (for further details on this matter see the Company’s news

release dated December 16, 2024). The current water exploration initiative represents an important

step in the development sequence of the Rio Grande Project , building upon previous drilling and

technical work.
