1.5 Mining Tenements The Mount Morgan Mine is the subject of 30 mining leases as described in Table 3 and displayed in Figure 2. Although Heritage Minerals is the holder of the Mining Leases (MLs) listed in Table 3, the site is managed by the Department of Natural Resources and Mines, Manufacturing and Regional and Rural Development (DNRMMRRD) through the Abandoned Mines Lands Program (AMLP). No other tenements exist over the site such as an EPM, EPC or Mineral Development License. As shown in Figure 4, the proposed Upper Mundic Gully TSF lies within ML5608 and ML5624. No change to any ML is necessary and no additional mining tenement would be required to accommodate the Upper Mundic Gully TSF.
