Great Basin Gold Provides Operational Update for the Quarter Ended March 2010

VANCOUVER, April 14 /CNW/ - Great Basin Gold Ltd. ("Great Basin" or the "Company") (TSX: GBG; NYSE Amex: GBG; JSE: GBG) provides a quarterly operational update for its Hollister (USA) and Burnstone (South Africa) projects.

Continued trial mining at the Hollister project resulted in the extraction of 25,777 ore tons containing an estimated 27,707 gold equivalent ounces(1) (Au eqv oz) at a grade of 1.07 oz per ton Au eqv (34.8 g/t Au eqv). This is a 40% improvement on the previous (Dec 2009) quarter.

Good progress has also been made with 2,270 ft (688 m) of underground development completed, with 1,149 ft (348 m) being in ore and 1,121 ft (340 m) in waste development. This is an improvement of 58% over the 961 ft (291 m) and 479 ft (145 m) reported respectively for the Dec 2009 quarter.

Underground exploration and stope delineation drilling has continued. In total, 32 stope-delineation boreholes (9,326 ft/2,826 m) and 9 exploration and cover boreholes (11,009 ft/3,336 m) were completed. Highlights include:

    
    -   further delineation of the North Clementine vein zone, where
        8 separate vein intersections were achieved and the strike extent of
        the zone has been extended to 500 ft (151 m);
    -   further extension of the main Clementine vein zone to the west; and
    -   continued indications of the development of the Gwenivere vein system
        at depth.
    

Detailed results from the exploration program will be released in a second quarter 2010 exploration update press release.

No surface exploration drilling was undertaken during the quarter as the Company is awaiting approval of updated surface exploration notice applications submitted to the Bureau of Land Management.

The Esmeralda Mill's operational performance improved with a total of 16,016 tons being processed in the quarter (quarter ended Dec 2009 - 8,070 tons). A total of 11,756 Au oz (quarter ended Dec 2009 - 5,295 Au oz) and 51,762 silver (Ag) oz (Dec 2009 - 25,380 Ag oz) were recovered. Mill recoveries of 77% for Au and 57% for Ag were achieved. Following the conversion to Carbon-In-Leach processing, recoveries of 92% for Au and 82% for Ag were achieved for the ten days following the conversion completed on March 23, 2010. The upgrade project that commenced in the last quarter of 2009 to improve recoveries and operational efficiencies has been completed except for the second carbon-stripping vessel, which will be installed during April 2010.

At the Company's Burnstone mine development project, the 7.5-meter diameter vertical shaft has been sunk to a depth of 1,506 ft (459 m), with 26 m (85 ft) remaining to shaft bottom. Development of shaft bottom infrastructure, i.e. loading facility, is underway. Shaft steelwork will commence at the end of April 2010 upon completion of the shaft bottom infrastructure.

The rock and man winder installations are currently underway, with completion also planned for April 2010.

Good progress has been made underground with drifts to access mining blocks B and C. As at March 31, 2010, a total of approximately 4,950 ft (1,500 m) of reef development had been completed, and 571 ft (173 m) of development remained on the decline shaft to link it up with the vertical shaft, with a total of 8,514 ft (2,580 m) of development being completed to date. A limited amount of mining, by way of Long Hole Stoping, has been undertaken and results are in line with expectations. As at March 31, 2010, approximately 80,000 ore tons (quarter ended Dec 2009 - approximately 60,000 tons) from mining and development had been accumulated on the surface stockpile.

Construction of the Metallurgical Plant continues with the major items, i.e. silos and other foundations, having been completed. Refurbishment of the Ball and Semi Autogenous Grinding mills was completed and these are ready for delivery to site. Metallurgical Plant commissioning is on track for end June 2010.

The Company also successfully negotiated the restructuring of the put option on the 51,500 Senior Secured Notes (the "Notes") issued in December 2008 with a settlement value of US$61.8 million. Of these, 7,000 Notes (value of US$8.4 million) will be settled in May 2010 by issuing the note holders 2.2 million shares at a price of US$1.75 and paying US$4.5 million in cash. The put option on 29,500 Notes (value US$35.4 million) will be cancelled and, therefore, will only remain on 15,000 Notes (value US$18 million). The cancellation of the put option removes the potential repayment of the Notes by December 2010 and provides the Company with the flexibility to settle the Notes any time on or before December 12, 2011.

Ferdi Dippenaar, President and CEO, commented: "We are making good progress at both operations with much improved performance at Hollister in Nevada, USA. Our target date for the delivery of the Burnstone Mine in South Africa remains the end of June 2010, with a significant number of milestones having been reached over the past three months. Much remains to be done, but we continue to be confident that the tight timelines will be met. Photographs and information on the progress at the site is being updated on our website on an ongoing basis. The US$47 million export loan facility obtained from Credit Suisse (announced on April 5, 2010) as well as the cancellation of the put option on the Senior Secured Notes provides the Company with significant flexibility and margin in available cash reserves to deliver both projects and meet our obligations as they come due."
