Great Basin Gold Ltd.: Underground Infill Drilling at the Hollister Project Continues to Confirm Deposit Prospectively
2008-08-05 07:30:00
VANCOUVER, BRITISH COLUMBIA–(EMWNews – Aug. 5, 2008) – Great Basin Gold Ltd. (TSX:GBG)(AMEX:GBN)(JSE:GBG) (hereafter “Great Basin Gold” or the “Company”) announces further results from underground drilling at the Hollister Project on the Carlin Trend in Nevada, USA. The underground holes are at 100 ft (30 m) spacing to fill in gaps, and better define and test areas identified for resource expansion within the Clementine and Gwenivere vein systems.
Drilling was conducted from January through June 2008. This work is part of a 28,000 ft (8,534 m) Phase One infill and exploration program, approved by the Company’s Board in November 2007, of which 18,000 ft (5,486 m) has been completed. Results from 30 holes are shown in the attached Table of Assay Results. Highlights include:

President and CEO, Ferdi Dippenaar, commented: “We are making good progress with the US$14.4 million exploration program we announced in December 2007. The focus of the in-fill drilling program has, at a cost of US$2.2 million, been to upgrade our resources from the Inferred to Measured and Indicated Categories. The remaining 10,000 ft to complete the underground in-fill drilling program will be completed during the second half of 2008. The focus will then shift to the planned US$4.5 million program to determine the strike and depth extent of the mineralisation.”

This release includes certain statements that may be deemed “forward-looking statements”. All statements in this release, other than statements of historical facts, that address possible future commercial production, reserve potential, exploration drilling results, development, feasibility or exploitation activities and events or developments that Great Basin Gold expects to occur are forward-looking statements. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include market prices, exploitation and exploration successes, continuity of mineralization, uncertainties related to the ability to obtain necessary permits, licenses and title and delays due to third party opposition, geopolitical uncertainty, changes in government policies regarding mining and natural resource exploration and exploitation, and continued availability of capital and financing, and general economic, market or business conditions. Investors are cautioned that any such statements are not guarantees of future performance and those actual results or developments may differ materially from those projected in the forward-looking statements. For more information on the Company, Investors should review the Company’s annual Form 40-F filing with the United States Securities and Exchange Commission and its home jurisdiction filings that are available at www.sedar.com.
Cautionary Note Concerning Estimates of Inferred Resources
This press release uses the term “inferred resources”. The Company advises investors that while this term is recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize “inferred resources”. “Inferred resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of a mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of economic studies, except in rare cases. Investors are cautioned not to assume that any part or all of an inferred resource exists, or is economically or legally mineable.
