Great Basin Gold Commences Trial Mining on Gwenivere and Clementine High Grade Veins at Hollister Project in Nevada

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 13, 2008) - Great Basin Gold Ltd. (TSX:GBG)(AMEX:GBN)(JSE:GBG) (hereafter "Great Basin" or the "Company") announces the results for the quarter ending June 30 2008.

One of the highlights of the period was the commencement of trial stoping on the Gweniviere and Clementine veins at the Hollister Development Project. A total of 16,128 tons has been mined, year-to-date, and 8,643 dry tons at a head grade of 0.975 oz/t (33.4 g/t) of gold and 9.6 oz/t (329.1 g/t) of silver have been milled from which a net of 8,714 gold equivalent ounces(1) were recovered. A total of US$7.8 million was recognized as revenue from trial mining activities at the Hollister Development Project.

The stockpile at Hollister has been increased to 7,485 tons at an estimated head grade of 1.0 oz/t (34.3 g/t) of gold and 10 oz/t (340.3 g/t) of silver at August 8 2008.

Underground cash costs associated with the tons milled totals US$443/oz, which was in line with expectations. Higher than expected toll metallurgical processing costs of US$192/oz was incurred on the milled tons and, as a result, the Company is currently reviewing alternative options for future treatment of its ore.

To allow for flexibility underground, waste development is ahead of schedule with 5,714 feet being completed compared to the planned 3,150 feet. This has resulted in an acceleration of pre-development expenses, which are currently being expensed as the full commercial Plan of Operations has not yet been approved.

During the quarter, the Company also announced a 60% increase in measured and indicated mineral resources at Hollister to 1.6 million ounces following positive results from underground and in-fill drilling (see News Release dated June 18, 2008).

Following positive surface exploration results indicating the discovery of a new vein system in the Hatter Graben area, it is anticipated that the US$14.4 million exploration programs at Hollister will be extended into 2009. Eight surface holes have been drilled in the Hatter Graben area; final assays have been received for three holes and results for five holes are pending.

At the Burnstone Development Project in South Africa, good progress was made with the construction of surface and underground infrastructure. At August 7 2008, 1,786 meters of decline development had been completed, with 414 meters remaining to the cross-cut to the gold-bearing reef. Exploration drilling on the initial mining block has indicated that the mineralized zone is 31 meters lower than anticipated, calling for approximately 180 meters of additional decline development. This could result in a potential three-month delay with access to the mining blocks now planned for the December 2008 quarter. This additional development is included in the 414 meters to the cross-cut. The additional development has some benefit in that a second mining block becomes accessible earlier, and it is expected that the 26,000-tonne bulk sample as well as the planned production build-up to 45,000 oz in 2009 will be achieved.

The sinking of the vertical shaft at Burnstone commenced during April and, to August 8 2008, had reached a depth of 80 meters below surface. The final depth of the shaft is planned at 501 meters.

The Company commenced a second phase program of approximately 28,000 meters of Air Core, RC and Diamond drilling at its exploration properties in Tanzania. Encouraging results have been achieved. It is expected that the results will be available in the December 2008 quarter, once assays are received. Exploration programs are also underway on properties in Mozambique (Tsetsera), Alaska (Ganes Creek) and Russia (Iturup, Kurils Islands).

Ferdi Dippenaar, CEO and President commented "We are pleased with the progress made with the trial mining at our Hollister Project. The Plan of Operations was submitted in April 2008, and the process is underway with comments having being received from the Bureau of Land Management. The situation at Burnstone Project in South Africa is similar. The application for a mining license was submitted in September 2007, and we expect to have the process completed by October of this year. Great Basin Gold is fully funded to complete its two development projects and exploration commitments with the signing of term sheets for $124 million in project finance using the Burnstone Project as collateral. This bodes well in what seems to be an extremely difficult market for gold producers who are in need of financing."
