Bulletin Resources (ASX: BNR) reports that recent mapping and rock-chipping at the Big pegmatite prospect within its Ravensthorpe Lithium project has identified outcropping, subcropping, and lag spodumene.
With this result, spodumene mineralisation has now been identified at three locations on the project’s Eastern Pegmatite Trend over a 2.5km length, with occurrences including Deep Purple, Creek, and now Big pegmatite.
Bulletin reports that mapping of the flat-lying to gently undulating Big pegmatite prospect has substantially increased the outcrop and subcrop size to approximately 700m x 500m, a tenfold increase from the previously reported size.
Ravensthorpe is located 12km south-west and along strike of the 210–220ktpa Mt Cattlin Lithium Mine
On-ground mapping has also extended the strike extent of the Eastern Pegmatite Trend to 4km, which remains unexplored and open to the north.
The company views the ‘significant’ size of these pegmatites as very important due to the potential for economic scale operations should drilling confirm sufficient thickness and lithium grades.
Ravensthorpe is located 12km south-west and along strike of the Mt Cattlin Lithium Mine (Allkem Limited), which accounted for 210–220ktpa of spodumene concentrate production in 2021, and sits on a 11.0 Mt at 1.2% Li2O mineral resource estimate.
Looking forward, Bulletin reports that it will continue with its mapping and sampling program while environmental studies, including seasonal flora and fauna surveys required for clearing permits progress.
Future work will also include soil sampling followed by drilling and other exploration activities.
