Mining

The Jonnagiri Gold Mine project was developed based on the pit optimization outputs considering East Pit as a standalone scenario targeting 495ktpa at a cut-off grade of 0.6g/t.

The current Mining Plan permits the mine to operate at 0.4 mtpa for mining. The current Mining Plan has to be renewed every 5 years. Mining in East block is planned with Open pit operation with drilling and blasting is planned. The proposed pit would progress from Northern to South. The bench height is planned at 7.5 m and the operating/ working width of the benches will be 10 m and the final width will be 6 m due to its highly compact and hard nature. Worked-out benches shall be planted at the end of life of mine. The modelling process carried out by Ukwazi South Africa is based on model types with specific block dimensions: Resource SMU model block dimensions & Mining block model or smallest/selective mining units (SMU)

Two mine design SMU models were generated by Golders for Ukwazi to establish the most suitable SMU size for the level of selectivity required for the mining operations. The SMU sizes investigated were: 5m x 5m x 2.5m & 5m x 5m x 5.0m. The image below indicates the isometric view of the East Block Pit Design and Selected Pushbacks
