Is there an unexpected increased amount of low-grade gypsum that is difficult to accommodate on-site?

There has been no increase in low-grade gypsum from original estimates encountered to date. In fact, all low-grade material has been used to construct and maintain site infrastructure such as roads and ditches. With a lot of the initial site infrastructure now complete, HRH can either stockpile the material on site or find a use for it within the local business environment.
