Tivan (ASX:TVN) reported a mineral resource estimate (MRE) update for its Speewah fluorite project in Western Australia, delivering an increase of 4% in total tonnage, with grade and contained calcium fluoride remaining broadly consistent with a previous estimate from February, according to a Tuesday filing with the Australian bourse.
The project now hosts indicated and inferred resources of 45 million tonnes at 7.8% calcium fluoride, containing 3.5 million tonnes of calcium fluoride, the filing said.
The February MRE was 43.2 million tonnes at 8.3% calcium fluoride, containing 3.6 million tonnes of calcium fluoride, an earlier filing showed.
The new estimate supports updated mine planning and production scheduling for a definitive feasibility study, with the company targeting a final investment decision for the project next year, per the Tuesday filing.
