Savannah Resources has reported more robust lithium intersections from the Mina do Barroso Lithium project in Portugal.

The company noted that the ongoing reverse circulation (RC) and diamond drill (DD) programme at both Grandao and Reservatorio deposits at the site has intersected lithium mineralisation over significant widths.

The drilling programme continues to expand the boundaries of the known mineralised pegmatites and as a result, the company expects the project to have further increases in the existing 14Mt mineral resource estimate.

So far, Savannah has drilled a total of 181 holes for 15,345m across three primary targets of Grandao, Reservatorio and NOA.

The highlights of the drilling results at Grandao include 25m at 1.56% lithium oxide, 22m at 1.41% lithium oxide and 20m at 1.42% lithium oxide, while the company found 32m at 1.18% lithium oxide at Reservatorio.

“The drill programme continues to deliver encouraging results.”

Savannah Resources CEO David Archer said: “The drill programme continues to deliver encouraging results, which will go towards further increasing what is already the largest spodumene lithium mineral resource estimate in Western Europe.

“We are upping the drilling tempo with the addition of a third rig and drilling, which commenced a little under one year ago, now totals over 15km in length and constitutes one of the most intensive drill programmes undertaken in Portugal in recent years.”

The objective of completing the diamond drilling was to obtain lithium bearing pegmatite for the metallurgical test work programme.

The company expects to receive a second diamond drill rig at Reservatorio to start geotechnical drilling as part of the feasibility study.
