Ongoing reverse circulation drilling at the Mina do Barroso lithium project in Portugal continues to return significant intersections of lithium mineralisation for Savannah Resources Plc (LON:SAV).
The drilling is designed to build upon the existing JORC resource of 32,000t of Li2O already defined at the Reservatorio deposit, one of three targets currently being evaluated.

So far, in the current programme, a total of 87 holes for 7,081 metres has been drilled. Broad zones of lithium mineralisation intersected giving further confidence of significant resource potential of Mina do Barroso
At the Grandao deposit, significant widths of lithium mineralisation have been identified. Key results include 59 metres at 1.13% Li2O from a depth of 5 metres and 33 metres at 1.22% Li2O from a depth of 40 metres.
Meanwhile, at the NOA deposit, drilling of a further six holes has confirmed the presence of lithium mineralisation over a 200 metre strike length together with good down dip extensions of at least 50 metres.

Key results include: 15 metres at 0.83% Li2O from a depth of 5 metres and 14 metres at 0.73% Li2O from a depth of 19 metres.
"The Grandao deposit is shaping up as a major additional component to the overall global Mineral Resource for the Mina do Barroso lithium project,” said chief executive David Archer.
