The original approval included mining of silica on Mining Leases M70/191 and M70/1055 (Cairn Hill). The latter was originally available for mining, but has been surrendered to become a nature reserve. Other mining leases nearby have also been explored for suitable quartzite, including Mining Leases M70/424, M70/425 and M70/2750.
