 Dear Friends of Gekko,In our information pack last week we covered the benefits of pre-concentration using gravity and flotation. This week we move on to the technology and concept that has significantly changed the treatment and recovery of gold in gravity gold circuits and now plays an important role in the treatment of flotation and gravity concentrates. Intensive Leach is a process that has had very rapid uptake in gold processing flow sheets and is now a standard addition.TECHNOLOGY RULES! INTENSIVE LEACH CELEBRATES 10 YEARSGekko’s patented InLine Leach Reactor (ILR) is the world’s market leader and the first commercialised Intensive Leach technology. The technology was developed to treat larger volume concentrates from Gekko’s first innovation, the InLine Pressure Jig. At that time, it was traditional to use tables to treat gravity gold concentrates posing both recovery and security threats.EARLY TRIALS AND CUSTOMER BREAKTHROUGHSThe first ILR prototype was designed and built in 1997. Metallurgical consultants such as Nick Moony and Rod Elvish played a critical role in the design and support of our first on-site trial at Mt McClure Gold Mine. This was only 18 months after the establishment of Gekko in January 1996. Mine Manager, Ian Gipps and Mill Super, Mike Martin are still in contact with Gekko today. This trial unit went on to be installed at Kundana and, impressively, is still in operation at Barrick’s high-grade Henty Gold operation in Tasmania today.Jack Baxter, Gold Room Foreman at Henty commented, “I have worked on six gold processing plants since 1988 and have run other Intensive Leach units, but the Gekko InLine Leach Reactor has been the one that stands out. I have treated over 600 batches with excellent recovery due to the fact that there is no channelling in the solids bed, hence the leaching is faster and more thorough.” 
1997 – First ILR prototype prior to shipment 2007 – Jack Baxter with first ILR prototype currently operating at Henty Gold Mine Another critical player in the growth and acceptance of the InLine Leach Reactor technology was George Potter (then Chief Metallurgist with Ashanti Goldfields in Accra, Ghana and now with Barrick, Toronto) who ordered five units for mine sites located in Ghana, Tanzania and Zimbabwe. The units were installed in by Gekko's Nick Katsikaros in 1999 and heralded a major step forward in the technology and strong support from the African subcontinent. KEY SUCCESS FACTORS> ILR recoveries reliably +98% on most gold ores> Only unit that can treat fines as well as coarse gold concentrates > Very high availability > Both batch and continuous units designed to meet customer requirements > Fully automated and exceptional technical design and quality > Now over 65 units installed worldwide in 21 different countries > A real success story giving us good reason to celebrate the ILR’s 10-year anniversary in 2007 DIGGERS AND DEALERSElizabeth Lewis-Gray, Tim Bell and I will be at the Diggers and Dealers Conference next week in Kalgoorlie, Australia. Please come and visit our stand no 21 and ask us questions about our latest research into underground processing technology.If you’d like to contact Jack Baxter his contact details are below Jack Baxter +61 3 6473 2474 jbaxter@barrick.com Yours sincerely,
