Mine Life2022
The DeGrussa Copper Operations (DeGrussa) include the high-grade DeGrussa and Monty Copper-Gold Mines.

Processing of ROM sulphide ore is expected to be completed by the end of October 2022, with the Sandfire investigating the potential extension of operations through processing of existing low-grade and oxide stockpiles using the existing plant. The processing plant is expected to continue operating until January 2023.

Summary:

The DeGrussa Operations includes both the DeGrussa and Monty Copper-Gold Mines.

DeGrussa
The DeGrussa Mine lies within the Proterozoic-aged Bryah rift basin that is enclosed between the Archaean Marymia Inlier to the north and the Proterozoic Yerrida basin to the south. The principal exploration targets in the Doolgunna Project area are Volcanogenic Hosted Massive Sulphide (VHMS) deposits located within the Proterozoic Bryah Basin of Western Australia. The style of mineralisation is considered to be from VHMS mineralisation.

The DeGrussa sulphide lode generally strikes towards NE with a strike length of approximately 230m, very steeply dipping towards the south with a plunge generally trending SW and having a vertical extent of about 180m.

The Conductor 1 orebody lies north of DeGrussa and generally strikes ENE dipping approximately 65° to the SE with a high-grade plunge trending SW. It has a strike length of about 540m with a vertical extent of 420m.

Conductor 4 orebody lies to the east of DeGrussa and Conductor1 and are stratigraphically deeper. They have an overall strike length of 470m and vertical extent of 260m. The upper sulphide lode strikes towards ENE with an approximate dip of 47° to the SE and high-grade plunge trending SE. The lower sulphide lode strikes E, dipping approximately 45° to the S with a SW high grade plunge.

Conductor 5 orebody is east of Conductor 4 and has a strike length up to 380m and a v ........

  • Longhole open stoping
  • Transverse open stoping
  • Longitudinal stoping
  • Cemented backfill
  • Dry waste backfill


Summary:

Production was sourced from the DeGrussa and Monty Mines with the mine remaining in balance between production and back-fill. Mine production rates from DeGrussa were slightly lower than planned due to contractor equipment and manning constraints. Monty mine production rates continued to exceed forecast.

The mining operations strategy adopted for the DeGrussa and Monty operations targets the blending of the material from both mines and scheduling to have both life of mine plans completed as close to the same time as practicable. The updated underground Ore Reserve continues to support this strategy with DeGrussa producing approximately 1.2Mtpa and Monty producing approximately 0.4Mtpa.

DeGrussa Mine
The underground mining method is long-hole open stoping (both transverse and longitudinal) with minor areas of jumbo cut and fill or uphole benching in some of the narrower areas. The primary method of backfill is paste fill. The sequence aims for 100% extraction of the orebody.

Primary mining methods employed are sub-level open stoping (SLOS) and long-hole open stoping (LHOS) with fill. Cut and fill techniques are also employed in remnant areas. Primary fill material is paste with minor use of cemented rock fill and rock fill when appropriate.
