"We expect to deliver a substantial conversion of previously estimated resource categories to higher grades as drill hole density increases throughout the deposit area, as well as a significant increase to the resource estimate of the high-grade core at Alpala. A further 70,000m of drilling has been completed since the development of the MRE in December 2017, and significant resource growth is expected in a revised MRE.""
