VANCOUVER, Oct. 20 /PRNewswire-FirstCall/ -- Great Basin Gold Ltd, ("Great Basin Gold" or the "Company"), (TSX: GBG; NYSE Amex: GBG; JSE: GBG) announces that the Nevada Division of Environmental Protection (NDEP) has granted approval of the Esmeralda Water Pollution Control Permit, allowing the Company to continue with the next phase of the Esmeralda Mill expansion. The Esmeralda Mill is part of the Company's Hollister Project in northeastern Nevada. The next phase of mill development includes construction, installation and commissioning of the Gekko System, an In-Line Leach Reactor (ILR) which optimizes the recovery of gold from high grade concentrate streams. In addition to concentrate leaching in an ILR, the Gekko system includes a gravity and flotation section, which will capture free gold and silver up front, thereby reducing the feed grade to the process flow. Esmeralda's ILR was shipped from Australia and arrived at site on September 25. Construction of the building and assembly of the components is expected to be completed in the fourth quarter, enabling high metal recoveries at Esmeralda's milling facilities. On September 9, 2009, the Esmeralda Mill started processing its first Hollister ore. As at October 4, 2009, a total of 5,502 tons of ore had been processed. The Hollister stockpiles are being sequentially depleted - low grade first, medium grade second, and then the high grade at a rate of over 240 tons per day. Low grade ore was selected to start the mill to reduce the risk of poor recoveries during commissioning. The high grade ore is planned for delivery at Esmeralda during the second week of October. The mill has averaged 217 tons per day since start up but, more importantly, for the 14 days up to October 4, the mill averaged 267 tons per day. Mill availability has increased to over 95%. An estimated 405 ounces of gold and 2,955 ounces of silver are in process and, when concentrated, will be forwarded to a refinery for recovery. President and CEO Ferdi Dippenaar commented: "NDEP's recent approval allows for installations for the Gekko System, including the extension of the current mill building to accommodate the System, a 50-foot thickener, a lime slaker system and a Genset to commence, thereby keeping to the project schedule. The completion of this phase of expansion paves the way to match processing capacity with the mining underway. The Hollister Project has suffered from the lack of consistent milling capacity, which also has impacted on the market's understanding of the overall operational performance. The Esmeralda Mill is expected to significantly reduce processing costs and assist in improved reporting and feedback on Project and Company performance."
