GREAT BASIN GOLD`S HOLLISTER PROJECT CONTINUES TO DELIVER EXCELLENT RESULTS
Highlights from underground drilling include 1.6 ft (0.5 m) grading 22.92 oz/t
(785.7 g/t) gold and 310.94 oz/t (10,661.1 g/t) silver in hole 175 and 0.6 ft
(0.2 m) grading 25.55 oz/t (875.97 g/t) gold and 10.24 oz/t (351.04 g/t) silver
in hole 158
July 9, 2007, Vancouver, BC - Great Basin Gold Ltd. (TSX: GBG; AMEX: GBN; JSE:
GB Gold) announces further results from underground drilling at the Hollister
Project on the Carlin Trend in Nevada, USA. The underground drill holes are
spaced at 100 ft (30 m) spacing to fill in gaps from surface drilling and to
define and test identified resource expansion areas within the Clementine and
Gwenivere vein systems. This new drilling information will not be taken into
account for the feasibility study, which is nearing completion, but will be
used for continuous adjustments to the current mining plans.
Continued drilling has addressed gaps identified in the database and has
started to expand the known mineral resources. The current work is part of a
second phase 40,000 ft drilling program of which just over 24,000 ft of the
program has been completed. Analytical results for the holes are being released
as they are received. Results for 25 holes are shown in the attached Table of
Assay Results - Underground Drilling.

The surface drilling program at Hollister has also progressed substantially and
will be enhanced by the addition of the Great Basin Gold`s own diamond drill,
recently purchased and now field ready. To date, 13 pre-collars (11,590 ft)
have been completed utilizing an RC drill rig and one pre-collar is in
progress. The RC rig has been utilized to complete 4 drill holes comprising
3,580 ft (1,090 m) of drilling. A diamond drill is currently drilling the tail
of the second pre-collar (1,113 ft completed to date). Twenty-eight drill
holes, totaling 48,850 ft (14,890 m) are planned on the Hollister property. Of
these, 11 holes, totaling 14,450 ft (4,400 m) are planned to test five targets
within the Hollister Development Block and 17 holes, totaling 31,400 ft (9,570
m) are planned in four target areas outside the Hollister Development Block
area.
Ferdi Dippenaar, Great Basin Gold President and CEO commented "Drilling
continues to intersect substantial bonanza-style grades and widths. Most
importantly, vein widths are holding up to expectations, which bode well for
ease of mining. With the information we have to date (the table of results is
available on our website) and the excellent results from continued drilling, we
fully expect to be able to expand resources at depth and along strike."

Samples collected from the Hollister Development Block Project are stored in a
secure facility until picked up by Inspectorate America Corporation
(Inspectorate) of Sparks, Nevada. Vein samples are analyzed by either metallic
screen or standard fire assay procedures. For metallic screen analyses, vein
sample preparation consists of drying and jaw-crushing the entire sample to 90%
passing 10-mesh, taking a 500 g sub-sample using a rotary splitter, and then
pulverizing the 500 g sub-sample to 90% passing 150-mesh using a large capacity
ring and puck pulverizer. Gold and silver determinations are by metallic
screen analysis, with two 1 assay-ton (30 g) fire assays completed on the fine
fraction; the coarse fraction is fire assayed in its entirety. For standard
fire assay, vein sample preparation consists of drying and jaw-crushing the
entire sample to 90% passing 10-mesh, taking a 300 g sub-sample using a Jones
splitter, and then pulverizing the 300 g sub-sample to 90% passing 150-mesh
using a large capacity ring and puck pulverizer. A 30 g charge is fire
assayed. All metal determinations are by gravimetric finish. Vein samples
analyzed by standard fire assay will be re-assayed using metallic screen
procedures. Laboratory Quality Assurance/Quality Control (QA/QC) is monitored
using coarse reject blanks and assay standards, duplicate fire assays, and
Inspectorate`s internal standards and blanks. Coarse blanks (barren rhyolite
or landscape marble) and assay standards are inserted into the sample sequence
as blind samples prior to submitting the samples to the laboratory.
Inspectorate also inserts assay standards and blanks into the sample stream.
QA/QC results are within acceptable limits.
