Potash West (ASX:PWN) had a productive day on Wednesday, announcing a significant increase in the phosphate and potash resources at the Dinner Hill deposit, located within its Perth-based Dandaragan Trough project. Specifically, the indicated phosphate resource rose to 250 million tonnes at 2.9 percent P2O5, using a cut off of 2.9 percent P2O5. That's a 108-percent increase for the resource and a grade increase of 4 percent. The phosphate resource also includes an indicated potash resource of 155 million tonnes at 4.1 percent K2O and an inferred potash resource of 20 million tonnes at 2 percent K2O. In total, that comes to an indicated and inferred potash resource of 175 million tonnes at 3.8 percent K2O, a 43-percent rise from the previous total. Outside the phosphate resource there is a further indicated potash resource of 18 million tonnes at 3.8 percent K2O.

The resource updates for Dinner Hill incorporate 2014 and 2015 drill results, including 90 aircore drill holes across 2,732 meters. That drilling extended the north-south length of the deposit from 4,000 meters to 7,200 meters, and the east-west width in the central area of the deposit from about 2,700 meters to 3,700 meters. Commenting further on the importance of that drilling, Potash West's managing director, Patrick McManus, said, "[i]mportantly, the mineral inventory for phosphate production has increased substantially, and there is still a significant area of the prospective Dinner Hill tenement to be explored. Phosphate and potash mineralisation are open to the east and to the south ... which offers considerable upside at Dinner Hill for increased project life, or capacity increases."
