New update from Savannah’s Mina do Barroso Lithium Project

Today Savannah Resources (AIM:SAV, SWB:SAV) have released new RC drill results from their Mina Do Barroso project in Northern Portugal as they try to add value to their existing  JORC compliant resource from 32,000t of Li2O at their Reservatorio target with drilling nearby at Grandao.

87 holes have been drilled across the deposits so far that have intersected broad zones of lithium mineralisation within the shallow, west dipping pegmatite body. A diamond  rig will be joining the project in February for deeper drilling into the vertical extent of the project and to explore the nearby Romainho, Campo de futebol & Peigro Negro exposures.


Li2O values at Grandao so far have peaked at 59m at 1.13%, 33m at 1.22%, 31m at 1.07% & 32m at 0.89% and there is potential for extension at depth, following the intrusive body south west into the country rock.

Savannah’s CEO, David Archer said:

“We are delighted to see the expanding geometry of Grandao with both near surface and deeper mineralisation. The Grandao Deposit is shaping up as a major additional component to the overall global Mineral Resource for the Mina do Barroso Lithium Project.

The overall tempo of activities continues to accelerate as the Project’s potential becomes more apparent. We are working to an aggressive timetable to deliver on a series of major milestones over coming months, which we believe will highlight the Project’s potential to be a key, up-stream component of the European lithium valued added chain.”

Liam’s Review:

In this early stage, this is an exciting project to watch and might be a big boost for the EU industry with more investigation. All Pegmatites can be entertainingly variable and the specific Li mineralogy, regularity of grain size and the associated gangue will ultimately define whether this is a valuable, mineable resource or just another beautiful pegmatite on the list of academic intrigue.

Portugal can be an exciting and an infuriating place to work. The authorities are not the most reliable or amenable to development across the spread of European nations, progress can be slow, or none existent once money has changed hands.

To add to the fun, protests can spring up and locals will force their noses in and make sure they’re given a reasonable say over the future of their land before any mining will be permitted, nobody wants another South European Skouries on their hands so, this will need to be a delicate operation. Other companies have backed out of Portugal Li projects recently.

This project’s success will depend on committed and honest community engagement, a solid academic understanding of the deposit’s and… a little bit of geo-luck!

It would be great if it goes ahead, if anything, just so us academic types can get some samples of the inner pegmatite system for research. We’ll keep the updates coming!
