Bacanora Lithium Plc said Oct. 9 that an updated measured and indicated resource estimate increased contained lithium by 30% at its 50%-owned Zinnwald lithium project in Germany.

The property hosts measured and indicated resources of 35.5 million tonnes grading 3,519 parts per million for 124,974 tonnes of contained lithium, at a lithium cutoff grade of 2,500 ppm.

A 2014 estimate, using the same cutoff grade, outlined measured and indicated resources of 26.6 million tonnes grading 3,620 ppm for 96,200 tonnes of contained lithium.

Meanwhile, current inferred resources stood at 4.9 million tonnes grading 3,549 ppm, representing 17,266 tonnes of contained lithium.

The upgraded resource was based on 76 surface holes plus 12 underground holes comprising 6,465 meters of core, and infill and verification drilling consisting of 15 surface diamond drill holes with a total length of 4,458.9 meters completed in 2017.

Bacanora secured a 30-year mining license for the Zinnwald project last year. A feasibility study is scheduled for completion in the second quarter of 2019.
