| Great Basin Gold provides operational update 
 VANCOUVER, Aug. 4, 2011 /PRNewswire via COMTEX/ -- REPORTS 100% INCREASE IN
 REVENUE
 
 Great Basin Gold Ltd. ("Great Basin Gold" or the "Company"),
 (CA:GBG)(GBG)(jse:GBG) reports an operational update for the 3 months ended June
 30, 2011. The Company will file its interim financial statements for Q2 2011 on
 August 15, 2011 and will hold an earnings call on August 16, 2011 at 9 am (EST).
 
 Great Basin Gold returned a much improved quarter in respect of Au and Ag ounces
 sold which combined with an expected improvement in cash costs should allow the
 Company to report adjusted earnings per share for the quarter (q1 2011:adjusted
 loss per share of $0.01).
 
 Hollister The Nevada operations recorded $49 million in revenue during the
 quarter on record sales of 34,522 Au eqv1 oz, an increase of 100% quarter on
 quarter. During the continuing construction and installation of the acid wash and
 carbon regeneration system at the Esmeralda Mill, loaded carbon is sent to the
 refiner as opposed to dore. Improved refining terms resulted in a decrease of
 approximately 5,000 Au eqv oz in inventory held at the refiner from Q1 2011. The
 Esmeralda Mill treated 22,237 tonnes during the quarter (q1 2011:21)(q1 2011:634)
 with a marked improvement in Au and Ag recoveries of 95% and 75%. Cash production
 costs for the quarter is expected to improve a further 8% quarter on quarter to
 approximately $611 per Au eqv oz in Q2 2011.
 
 Underground exploration and stope delineation drilling continued during the
 quarter, with a record footage of 45,000 feet or 13,636 meters completed from 84
 boreholes. The focus has been on completing phases of drilling on the Blanket
 Zone and south east Gwenivere targets, providing further data for incorporation
 in the upcoming mineral resource update (anticipated release date September
 2011). The stope delineation drilling has continued to tighten up controls for
 short interval trial stope planning. Surface exploration has continued collating
 geological and geophysical data as well as reviewing surface expressions of
 interpretations with structural and geological observations.
 
 Burnstone Operational efficiencies at Burnstone improved significantly with
 mechanized ore development increasing by 33% quarter on quarter to 1,550 meters
 in addition to 1,872 meters of waste development completed during the quarter.
 The increase in ore development allowed for an increase of 36% in the square
 meters stoped quarter on quarter. Despite the relatively close drill spacing in
 the current mining area, the exact position and orientation of geological faults
 could not be identified earlier as most of these are of a graben nature.
 Additional infill and delineation drilling as well as extensive mapping and
 interpretation of the structural information from the over 10 kilometers of
 underground development, now provides management with more detailed data to
 incorporate these faulting into the mine plan. An additional 66% waste
 development was completed during the 6 months ended June 30, 2011 in response to
 the geological faulting encountered compared with the original planned meters.
 
 Excellent progress has been made with long hole stoping as the mining method,
 with the efficiency of the teams improving on a monthly basis. The improved
 hanging and footwall conditions experienced in the C block allowed for a
 significant improvement in decreasing the stoping width which was measured as low
 as 67 cm in some stopes. This also had a positive impact on the mining grade of
 stope material which improved 60% from Q1 2011.
 
 The Metallurgical Plant is performing in line with expectation with approximately
 202,660 tonnes processed during the quarter (q1 2011:199)(q1 2011:878
 tonnes).Tonnes processed however remain predominantly from development ore which
 includes more dilution than stoped material and negatively impacts on the mill
 head grade. Recoveries for the quarter improved to 85% (q1 2011:83%) although
 still impacted by the low head grade ore delivered to the mill.
 
 Recoveries are expected to improve to the planned 95% as the head grade
 increases. The impact of the lower head grade is reflected in the 5,619 Au ounces
 sold (q1 2011:2)(q1 2011:794 Au eqv oz) as well as the cash production cost per
 ounce of approximately $1,450 (ZAR 10,130) expected for the quarter. During the
 build-up phase a more accurate measurement is cost per tonne which improved 12%
 to approximately $60 (ZAR420) (q1 2011:$68) per tonne for the quarter.
 
 _________________________ 1 Au eqv oz is calculated based on US$1,400Au and
 US$30Ag.
 
 Corporate The Company, with the assistance of RBC Capital markets, offered a
 $0.07 per warrant early exercise discount to holders of the $1.25 warrants
 expiring November 2011. Ten million of the warrants were exercised prior to June
 30, 2011 with another 9.2 million warrants exercised subsequently, leaving
 approximately 223,000 warrants to be exercised prior to expiry on November 15,
 2011.
 
 The Company had approximately $38 million in cash reserves on June 30, 2011 and
 has also negotiated a US$40 million standby debt facility with Credit Suisse AG.
 This facility will be available in the event that additional working capital is
 required at Burnstone as a result of the slower than planned production build-up.
 Legal documentation is nearing completion with the targeted signature date being
 mid-August, 2011.
 
 Ferdi Dippenaar, Great Basin Gold President and CEO, commented: "Although
 experiencing the usual challenges with bringing a new mine into production,
 Burnstone is settling into a production rhythm and although the progress made by
 the team on a monthly basis is reassuring, it is not yet at planned levels. The
 need for additional waste development to access the mining blocks impacted
 negatively on ore development which in turn impacts on stopes available for
 mining. Production for the remainder of the year will unfortunately be impacted
 by this approximate 3 month delay in ore development and we expect to recover
 between 50,000 to 60,000 Au oz for the second half of the year and an estimated
 60000 to 70000 ounces for the 12 month period. The Nevada operations showed
 improvements in a number of areas during the quarter, notably in ounces extracted
 through trial mining as well as the improved recoveries at our Esmeralda Mill.
 The latter improvement is especially pleasing with the impact already evident in
 the reduced cash costs and the increased ounces delivered to the refinery. The
 current performance from our Nevada operations and the standby debt facility
 provides the Company with adequate cash resources to fund the delayed production
 build-up at Burnstone. Our short to medium term focus at both of these operations
 remains to increase production, manage costs and unlock the intrinsic value of
 these quality projects."

 Cautionary Note regarding Non-GAAP Measurements
 
 Cash production cost per ounce/tonne is a not a generally accepted accounting
 principles ("GAAP") based figure but rather is intended to serve as a performance
 measure providing some indication of the mining and processing efficiency and
 effectiveness. It is determined by dividing the relevant mining and processing
 costs including royalties by the ounces produced/tonnes milled in the period.
 There may be some variation in the method of computation of "cash production cost
 per ounce/tonne" as determined by the Company compared with other mining
 companies. Cash production costs per ounce/tonne may vary from one period to
 another due to operating efficiencies, waste to ore ratios, grade of ore
 processed and gold recovery rates in the period. We provide this measure to our
 investors to allow them to also monitor operational efficiencies. As a Non-GAAP
 Financial Measure cash production costs should not be considered in isolation or
 as a substitute for measures of performance prepared in accordance with GAAP.
 There is material limitations associated with the use of such Non-GAAP measures.
