Processing: Circuit Post Acquisition Review
• 1. Closed Circuit SAG (CCS)• Closed circuit SAG, isolate ball mill and cyclone feed pumps and run SAG only on secondary crushed
product.• 2. SAG and Ball Mill Closed Circuit (SABC) - reduced power
• Reduce ball charge in SAG and ball mill, both crushing and mill circuits operate as normal at reduced tonnes.
• 3. SABC campaign milling• Campaign milling 350 tph SABC Secondary Crushed Feed• Campaign milling, 350 tph SABC, Secondary Crushed Feed.
Key assumptions• Budgeted throughput reduced to 350tph (from 380-400 tph) to stabilise circuit and optimise recoveryg g p p ( p ) p y• Campaigns run for ~16days per month – Opportune maintenance during downtime• Owner maintenance crews assist with small capital projects during plant shutdown• Reduce capital required for Tank refurbishment (3 Leach Tanks remain offline)• Reduced manning from 89 to 69• ROM Load and Haul – opportunity remains to reduce Crusher feed costs
