Stage 1 mine plan comprises open pit production from Grants and Hang Gong and underground at Grants, BP33 and Carlton prospects.
Grants Open Pit
Mining of Grants will be undertaken by a Mining Contractor using conventional open pit mining methods.
The pit will be mined in two stages; Stage 1 will target early ore by reducing the volume of pre-strip waste to be mined with Stage 2 a cutback out to the final pit limits.
Mining will predominately occur concurrently within both stages over a 9-month period to ensure continuity of ore supply to the crusher with Stage 1 anticipated to start only 2 months before Stage 2. First ore will be mined in Month 6 of the mine schedule, with mining activities continuing in Grants until Month 31.
Hang Gong Open Pit
The Hang Gong pit design was completed using the same design parameters as Grants with a combination of dual lane and single lane ramps utilised. The pit will be mined as a single phase.
Combined with Grants, the two open pits only contain 5% Inferred Resources & together they support 3 years and 45% of the contained metal of life of mine processing requirements.
Hang Gong Pre-strip commences in Month 60 (Year 5, Month 12) for 10 months before ore is exposed. Mining continues for an additional 19 months until mineral inventory is exhausted, with mining activities ceasing in Month 88.
All material (ore and waste) will require drill and blast, exce ........
