Dinner Hill Phosphate Deposit
- Phosphate Indicated Mineral Resource increased to 120Mt @ 2.8% P2O5, 3.1% K2O, and 8.2% CaO
- Metallurgical breakthrough brings major cost benefits
- Resource tonnes increased by 33%
- Projected mine life of 20 plus years
As quoted in the press release:
The OBM block grades were estimated by geostatistical interpolation using the inverse distance squared method. Parent block sizes were 100m x 100m x 1m vertical. The Dinner Hill Phosphate Deposit is now estimated to contain an Indicated Mineral Resource of 120Mt at 2.8% P2O5, 3.1% K2O, and 8.2% CaO above a lower cut-off grade of 2.15% P2O5 (Table 1).
Potash West Managing Director, Patrick McManus, said:
The metallurgical breakthrough we have made with regard to removing the chalk through the processing stream is very significant in that it not only increases the size of the resource and grade of the phosphate at Dinner Hill, it potentially can lead to major mining cost savings through the creation of a simpler mining process, a lower strip ratio and an increased mine life.
