Savannah Resources Plc (LON: SAV) has completed the first phase of an exploration programme aimed at defining a JORC resource at the Mina do Barroso lithium project, located in northern Portugal.
Savannah has a 75% interest in Slipstream Resources Portugal Unipessol Lda, which is the registered holder of the Mina do Barroso mining licence.
The company undertook geological mapping to define the extent of the lithium-bearing pegmatites at Mina do Barroso in preparation for drilling. The mapping took place across three primary target areas - Grandao, Reservatorio and NAO - which have been shown to have relatively high grades of lithium oxide with drill results up to 1.67% Li2O over significant widths.
The mapping has duly expanded the surface footprint of the known pegmatites and a 3,000-5,000 metre reverse circulation drill programme is scheduled to start during the week commencing 17 July 2017, focusing on defining a JORC mineral resource estimate to support a potential mine development.
"We're pleased that our mapping, as a preliminary to drilling, has extended the surface expressions of three major lithium bearing pegmatites at Mina do Barroso,” said Savannah chief executive David Archer.
“This will help us in our drill hole targeting for our upcoming drill programme as we look to ultimately define a JORC resource to support mine development. Based on previous drilling and channel sampling, the three pegmatites mapped have been shown to have relatively high-grades of Li2O and we look forward to converting this into a commercial resource."
