- Savannah Resources said preliminary metallurgical test work on a composite lithium sample from the Mina do Barroso project in northern Portugal confirms that a very pure low iron spodumene concentrate can be produced.

Savannah has a 75% interest in Slipstream Resources Portugal Unipessol Lda, which is the registered holder of the Mina do Barroso mining licence.


- Metallurgical test work undertaken on a composite sample from Mina do Barroso to determine if lithium bearing minerals can be recovered using commercially available technology to produce a saleable product;

- Work confirms that a high-grade, very pure, low iron spodumene concentrate can be produced;

- Single analysis of the combined sample confirmed a high Li₂O head grade (~1.95% Li₂O) and low Fe₂O₃ head grade (~0.9%);

- Heavy Liquid Separation ('HLS') shows a very pure (~8%) Li₂O product can be produced;

- Floatation results utilising a simple one stage float without any optimisation achieved ~83.7% Li₂O recovery at ~5.9% Li₂O, this is very positive and can be improved through optimisation;

- Microscopy confirmed that the concentrate was almost entirely spodumene with only very minor amounts of petalite;

- Test work confirms that a high quality spodumene concentrate can be produced using conventional commercially available processing technologies; and

- 3,000-5,000m drill programme to commence shortly, focusing on defining a JORC mineral resource estimate to support potential mine development.
