"The acquisition provides an additional 400m to the east and 400m to the north of the flagship 775,000oz Rebecca gold deposit, allowing important operational flexibility with respect to pit design, access and hydrology as the company moves forward from exploration and resource definition into options analysis and commercial studies," Apollo said.
A new Apollo resource estimate is in train, as is further exploration drilling.
