Niobe Project (Sold)
Niobe is a project with shallow, high-grade tantalum mineralisation ready to drill, and the possibility of lithium.
- This is a tantalum-lithium pegmatite project
- Single granted prospecting licence (P59/2137) covering 2 square kilometres
- 100% Meridian 120 owned
- Lies in the Dalgaranga greenstone belt, 70 km north-west of Mount Magnet, in an area noted for tantalum and beryllium deposits
- Licence area contains numerous flat-dipping pegmatites containing tantalum, beryl and traces of lithium
- A small open pit excavated at Niobe in 1995 produced about 20,000 tonnes of very high grade ore (> 500 ppm Ta2O5)
- There are shallow, high grade intersections in drill holes just outside the pit and the mineralisation is open at depth
- There are assays over 1000 ppm Ta2O5 in deeper holes nearby
- There has been extensive past drilling on several prospective pegmatites, but all of it is shallow and known mineralisation remains open down dip
- There has been no systematic exploration for lithium. Only 13% of historical drill holes were analysed for lithium, and these are all clustered in a small area. Numerous other pegmatites have never been sampled for lithium
- The best lithium drill results recorded are 1.27%, 0.69%, and 0.52% lithium oxide. There is also a single rock sample from a costean showing 2.13% Li2O
- About half of the drill holes that have been analysed for lithium show significantly anomalous values (above 0.2% Li2O). The anomalous lithium can occur over a substantial thickness – hole MTF10 has 13 metres (approximate true width) averaging 0.39% Li2O (best value 0.69%)
- The prospect is now sold.
