Brazilian Rare Earths (ASX:BRE) said diamond drilling confirmed an ultra-high-grade rare earth element-niobium-scandium-tantalum-uranium deposit at the Sulista West trend within the Sulista project in Brazil, according to a Thursday Australian bourse filing.

A significant intercept encountered during the drilling included 20.4 meters at 11.8% grade of total rare earth oxides, 23,024 parts-per-million of neodymium-praseodymium, 1,009 ppm of dysprosium-terbium, 3,006 ppm of niobium pentoxide, 224 ppm of scandium trioxide, 175 ppm of tantalum pentoxide, and 1,011 ppm of triuranium octoxide from 17.6 meters. It noted that the diamond drilling results returned the highest uranium and tantalum grades since exploration began in 2021.

The firm will now conduct high-resolution drone-based geophysical surveys and geological mapping across the project to guide a targeted step-out diamond drilling program.

It also plans to focus on drone-based geophysical surveys coupled and geological mapping across the Sulista North area. It is conducting diamond drilling of priority rare earth element-niobium-scandium-tantalum-uranium drill targets with a 3,000-meter program at the Sulista East area.

Its shares climbed 3% in recent trading on Thursday.
