Cycladex Process

• Quicker leach times 4h vs 36h
• Higher recoveries typically 5%
• Environmental concerns reduced
• May work where gold is refractory (i.e. – those deposits where gold is trapped in minerals which can’t be leached by cyanide easily)
• Lower cost, lower CAPEX

Cyanide Process

Cyanide revolutionized the recovery of gold from lower-grade and non-refractory deposits.

But it comes with its challenges

• Additional costs (operating and capital)
• Safety aspects in transport, storage and use
• Community concerns
• Not without its problems. e.g Baia Mare tailings spill in Romania
