Commerce has outlined an indicated resource for the Upper Fir totaling 11.30 million tonnes grading 198 grams per tonne Ta2O5 and an inferred resource of 26.20 million tonnes grading 194 grams per tonne Ta2O5. The Fir deposit hosts an indicated resource of 5.65 million tonnes grading 203.1 grams per tonne Ta2O5.
