Mineralization. Mother Lode is characterized as a sediment, intrusive, and locally volcanic-hosted disseminated gold deposit. Mineralization most closely resembles Carlin-type sediment-hosted gold deposits of north-central Nevada. The Mother Lode deposit formed at ~12.7 Ma, which is much younger than the typical ~40 Ma age in north-central Nevada.
The Outotec BIOX process for the treatment of refractory gold concentrates has been in commercial operation for over 30 years with 13 successful Outotec BIOX plants commissioned worldwide. To date, over 22 million ounces of gold have been produced through this process.
Sulfide gold mineralization at Fosterville is relatively homogenous with orogenic gold deposits, however with minor variations in the host rock type and structural setting. Deposits similar to Foserville form a subgroup of orogenic gold deposits that are typified by gold occurring in fine crystals of arsenopyrite and/or pyrite disseminated in country rocks as a selvage to faults or veins.
BIOX ® vs Biooxidation • Biooxidation is a bio-hydrometallurgical process for the pre-cyanidation treatment of refractory gold concentrates. This includes: • Tank Bioleaching • Heap Bioleaching • Vat Bioleaching • BIOX ® is the patented process using stirred tanks reactors.

· Its BIOX processing circuit was the first of this type to be launched in Eurasia. Additionally, in June 2016 Suzdal became the second mine worldwide to launch an innovative Outotec HiTeCC (Hot Leach) process to recover gold from both historical and CIL future tailings.
Gravity recoverable gold from the mill discharge is recovered in a gravity circuit achieving approximately 25% gold recoveries. This is followed by the well-established bacterial leaching (BIOX®) technology, which utilises cultivated bacterial which converts the sulphide minerals and exposes the gold for subsequent cyanidation.

The washed BIOX ® product would normally contain less than 1 g/l total iron in solution with an acid pH of 1‐3. Iron removal is necessary before cyanide leaching to promote gold recovery and reduce cyanide consumption. Neutralisation
Two days of presentations were heard with delegates representing BIOX® operations and projects in Australia, South Africa, Kazakhstan, Russia, Philippines, Zimbabwe and Malaysia. A site visit was also made to FCF Minerals Runruno BIOX® Gold operation.
· Mining and processing at the Australian gold project. Mining at the Matilda, Williamson and Galaxy deposits is proposed to be performed using open-pit method integrating standard truck and excavator operations, as well as conventional drill, blast, load and haul. The open-pits are located within a 20km radius of the existing processing facility.

· The crusher and mill are located at the mine portal (3,140m above sea level). The concentrator, flotation circuit and BIOX® facility are located at a lower elevation, along the main highway near the Rimac River. The concentrator has produced zinc, lead and copper
Since that time, the comminution and flotation circuits in the oxide plant have been operated periodically to supplement flotation concentrate supply to the sulphide plant''s BIOX circuit. Since July 2011, the oxide plant has been refurbished, from the crusher to the carbon treatment and gold room circuits, at a capital cost of about $3 million.
Further metallurgical testwork confirms high gold recoveries at the Mallina Gold Project Highlights: Gravity testwork on three composite samples from Brolga achieved gold recoveries of 12.4%, 27.3% and 12.1%. Gravity testwork will continue on samples
