GREAT BASIN
REPORTS NEW EPITHERMAL VEIN
DISCOVERIES AT HOLLISTER PROPERTY
July
29, 2009, Vancouver, BC -
Great Basin
Gold Ltd, ("Great Basin" or the "Company"), (TSX: GBG; NYSE
Amex: GBG; JSE: GBG) announces the discovery of new epithermal veining adjacent
to the Gwenivere and Clementine systems at its Hollister gold property on
the Carlin Trend in Nevada, USA.
Underground evaluation and exploration drilling during the second quarter
of 2009 continued to deliver new high grade vein intersections. During this
period, a further 29,586 feet (8,965 meters) was completed, totaling 43,163
feet (13,080 meters) for the year. Significant intersections in two newly-discovered
epithermal veins have been returned from exploration drilling conducted at
end of the west lateral development. Drilling of "Blanket-style" disseminated
mineralization, hosted within the overlying Tertiary volcanic rocks has also
returned encouraging results. Drilling continues to deliver high-grade intersections
on the Clementine and Gwenivere vein systems in the main Hollister Development
Block ("HDB") area.
Underground drilling is providing considerable definition to the strike (3000
ft/980 m) and vertical depth (1300 ft/396 m) continuity of the Clementine
and Gweneviere vein systems. Geological mapping and structural studies have
led to step-out targets northwest of these vein systems. This drilling has
yielded immediate confirmation of at least two new and separate vein systems.
The main HDB mineral system has been recently remodeled, and currently comprises
21 discrete east-west striking subvertical veins, which constitute the Clementine
and Gwenivere groups. This system is still open along strike, at depth, and
in areas up to and above the Ordovician/Tertiary Unconformity (termed "Blanket
Zone").
During the quarter, the number of active underground drilling rigs was doubled
to four. The drilling complement now comprises two stope delineation rigs,
a vein extension or cover rig, and an exploration rig.
New Vein Discoveries
To date, seven (7) boreholes have tested a target area northwest of the current
Clementine vein system. This drilling has been conducted north-westwards from
the West Lateral drill station (shown as West Lateral system in the table
below). Assay results are just being received.
HDB-307
(
Azimuth = 330 deg, Inclination = -5
deg) intersected quartz veining from 584.8 - 587.0 ft (2.2 ft/0.7 m) that
grades
3.16 opt (108 g/t) Au and 19.6 opt (672 g/t) Ag
. The intersection
includes 1.2 ft of lattice bladed and druzy quartz veining with visible gold
and naumannite grading
5.089 opt (174 g/t) Au and 34.315 opt (1176 g/t)
Ag
; and 1.0 ft of weak quartz stockwork with fragments of quartz vein
grading
0.836 opt (29 g/t) Au and 1.983 opt (68 g/t) Ag
.
HDB-293
(Azimuth = 330 deg, Inclination = +12 deg) intersected
quartz veining from 599.8 - 602.0 ft (2.2 ft/0.7 m), characterized by
quartz vein stockwork and vein breccia which grades
0.154 opt (5 g/t) Au
and 2.713 opt (93 g/t) Ag.
HDB-309
(Azimuth. = 330 deg, Inclination -30 deg) penetrated
a significant, previously unrecognized 16.5 ft (5 m) quartz vein zone from
783-799.5 ft (238.7-243.7 m), located within a broader 30 ft (9 m) deformation
zone. This 16.5 ft (5 m) interval includes zones of heavy white clay and milky
quartz veining cut by veins with grey quartz and minor naumannite (Ag-selenide),
quartz vein brecciation, and two notable areas with strong adularia coating
on fractures. Silver values to 0.9 opt (28 g/t) with low gold have been received
to date; the current interpretation is that this vein setting is high up in
the mineral system.
Follow-up drilling is currently being conducted to expand the understanding
of the geological setting of the mineralisation. The first borehole, HDB-310
(Azimuth = 320 deg, Inclination -30 deg), has also intersected the northwest
strike continuity of the zone intersected in HDB-309. The borehole intersected
a zone of brecciation, quartz veining and intense adularia flooding from 1280-1340
ft (60 ft/18 m). Assay results are awaited.
Blanket Zone Drilling
Another highlight of the exploration drilling is the intersection of Blanket
Zone mineralization which is hosted in the Tertiary volcanic rocks above the
Tertiary-Ordovician Unconformity. Borehole HSD-64 intersected
31 ft (9.4
m) grading 0.78 opt (26.61 g/t) Au.
This disseminated style of mineralization
is linked to the presence of mineralized structures within the Ordovician
metasedimentary rocks and into the Tertiary volcanics, where there are effectively
"blow-outs" of mineralizing fluids. These are expressed at surface
as geysers, steam vents and chalcedonic quartz accumulations with associated
mercury mineralization. A preliminary examination of over 900l drilling intersections
in the Tertiary volcanics indicates a significant unexploited resource in
the vicinity of Hollister, as well as satellite targets such as Butte and
Velvet, The geological continuity and economic viability (grades are generally
between 1-6 g/t Au) of this zone is being assessed.
Clementine Vein System Drilling
Twenty-two (22) cover boreholes have been drilled northwards from the 4705
Decline to test the Clementine vein system. Intersections range from
0.11
opt to 4.36 opt (3.67g/t to 149.55 g/t) Au over widths 0.4 ft to 5.0 ft (0.13
m to 1.5 m).
Gwenivere Stope Delineation Drilling
Twelve (12) stope delineation boreholes were completed targeting the Gwenivere
system. The Gwenivere drilling indicates vein mineralization ranging from
0.13 opt to 9.14 opt (4.4 g/t to 313.4 g/t) Au over widths of 0.6 ft to
5.4 ft (0.1 m to 1.6 m).
Additional details of the results are provided in the Table of Hollister Drilling
Highlights (attached) and on the Great Basin website.
Underground Geological Mapping
A program of detailed geological mapping in the underground development has
been implemented. Ore controlling structures have been identified and are
being modeled. This exercise has also exposed a number of vein targets that
are being further evaluated by diamond drilling.
Surface Exploration
No surface drilling has been undertaken during the quarter. A program to further
investigate the Hatter Graben target to the east of the Clementine - Gwenivere
vein cluster is planned. A strike extent of approximately 3,000 ft (915 m)
and a width of up to 1,320 ft (400 m) in the Hatter Graben target-area have
been tested to date.
Previous geophysical (eg airborne magnetic and radiometric, ground gravity,
Induced Polarization and resistivity) surveys on the Hollister property are
being integrated with the current drillhole data. The revised interpretations
are planned to highlight ore controlling structures, as well as assist in
prioritizing follow up targets. Significant exploration potential remains
to be tested on the surrounding claim areas of the Hollister property. A total
of sixteen (16) targets have been identified for future exploration.
Ferdi Dippenaar, President and CEO, commented: "The emerging potential
of the Hollister vein system, shown by the discovery of another vein system
west and northwest of our current infrastructure, is very exciting. We have
extended our exploration activities in this new area. The ongoing exploration
success at Hollister underscores the prospectivity of the property. Our geology
and exploration work is steadily generating a predictive model for the Hollister
system which will assist with ongoing exploration as well as increasing confidence
levels in our production planning."

Samples collected from the Hollister Development Block Project are delivered
to Inspectorate America Corporation (Inspectorate) in Sparks, Nevada. Vein
samples are analyzed by standard fire assay procedures. 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. 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.
