Oceana has kicked off field exploration at its lithium projects in Brazil and Australia just a little more than a month after listing on the ASX.

At its flagship Solonopole project in Ceara State, northeastern Brazil, the company will start detailed mapping and sampling in the coming week to follow-up on high-grade lithium samples grading up to 9.2% Li2O which were taken from the Lapinha zone to the south.

Lithium-caesium-tantalum (LCT) mineralised pegmatites had historically been targeted by artisanal miners in this area for lithium, tantalum, niobium and tin to less than 10m vertical depth.

Oceana Lithium’s (ASX:OCN) upcoming field work will be combined with a regional exploration database which it had acquired from a previous explorer to guide drill target ranking for the maiden drilling campaign later in the year.

It follows recent moves by the Brazilian government to ease the way for lithium explorers in a bid to become a major player in the sector, with an executive order removing the need for lithium exports to be approved by the Science and Technology Ministry’s nuclear energy committee.

Solonopole contains more than 17km of intermittent outcropping lithium-bearing pegmatites, just three hours by sealed road from Fortaleza port.

Meanwhile, in the Northern Territory, the company has mobilised an exploration team to start mapping and sampling of historical mineral occurrences within the Mt Denison tenement.

Nine mineral occurrences were recorded by the Northern Territory Geological Survey, three of which are associated with pegmatites.

However, while historical samples have returned 35.4% tantalum and 18.5% tin, they were never assayed for lithium.
