Goldrush Resources Ltd. (TSX VENTURE:GOD)(OTCQX:GDRRF) ("Goldrush" or the
"Company") is pleased to announce the results of a shallow Rotary Air Blast
("RAB") drilling program on the Company's Pompoi permit which is contiguous with
and to the east of Roxgold Inc.'s ("Roxgold") Yaramoko permit. The program
included 5,433 metres of RAB drilling in 197 shallow holes along two fences
oriented to traverse an interpreted east-west gold anomaly located in the
southwest quadrant of the Pompoi permit. This anomalous area is 2.9 kilometres
east of Roxgold's recent Bagassi Central "55 Zone" high grade gold discovery.
Drill fence #1 was drilled across the southwest corner of the Pompoi permit in a
southeast-northwest direction over a linear distance of 2.08 kilometres.
Coverage and testing of the saprolite on this line was approximately 85% with
short gaps of from 10 to 55 linear metres and totalling 295 linear metres,
occurring where the RAB drill encountered thick laterite gravel and/or the water
table. Assays of the drill samples revealed the presence of four, two metre
thick mineralized intersections that varied from 0.47 to 7.40 g/t Au. Three of
these intersections occurred in laterite gravels and may have been transported
an undetermined distance from a bedrock source.
Hole PPRB11-110, the most westernmost hole on drill fence #1, was collared
approximately 45 metres from the commonYaramoko-Pompoi property boundary. The
intersection of 0.47 g/t Au over 2 metres at a vertical depth of 27 metres in
hole PPRB11-110 occurred in quartz veining in granitic saprolite, which is very
similar to the host rock setting at the Bagassi Central discovery. The
intersection in hole -110 is open in all directions and the orientation of the
mineralization is unknown at this time.
Drill fence #2 was drilled over a linear distance of 1.54 kilometres across the
southwest corner of the Pompoi permit, subparallel to and approximately one
kilometre northeast of drill fence 1. Coverage and testing of the saprolite was
limited to approximately 25% with gaps varying from 30 to 760 linear metres and
totalling 1180 linear metres, due to the presence of thick laterite gravels, a
shallow water table and the dwellings of a native village. As a result, the
program did not conclusively test the soil anomaly along this line and an
alternative drilling method (air core or RC drilling) may be required in this
area.
Hole PPRB11-176 on drill fence #2 intersected 2.3 g/t Au over 2 metres at a
vertical depth of 10 metres, this intersection also occurring in granitic
saprolite, which is similar to the host rock setting at the Bagassi Central
discovery. The intersection in hole -176 is open in all directions and the
orientation of the mineralization is unknown at this time.
Commenting on the results of this initial drilling program Len Brownlie,
President and CEO of Goldrush, noted: "The initial RAB program on the southwest
quadrant of the Pompoi permit has been successful in demonstrating the presence
of gold mineralization in a similar setting to that encountered by Roxgold at
Bagassi Central. Roxgold's nearby success, combined with data from regional
aeromagnetics and the results of our soil geochemistry and RAB drilling have
confirmed that the Pompoi permit contains highly prospective targets that will
require near term follow up. Coupled with our recent drilling success at our
Ronguen gold deposit and our pipeline of 10 other exploration projects in
Burkina Faso, we look forward to a very active and successful 2012 exploration
campaign."

A total of 5,433 metres was drilled in the 197 RAB holes, which were
continuously sampled at two metre intervals for assaying. This drilling program
marks the second phase of exploration on a portion of the Pompoi permit in
conjunction with the recent high grade drilling results by Roxgold on its
Yaramoko permit.
This southwest Pompoi gold-in-soil anomaly was defined by reconnaissance scale
(400 by 200 metre) soil sampling that partly defined an anomaly of greater than
13 ppb gold which contained eleven anomalous gold values, with individual high
values up to 504 ppb gold (See Goldrush news release dated September 7, 2011 for
full details). The anomaly has been traced over a north-south distance of 1,600
metres and westerly for 1,400 metres to the common boundary of Pompoi and
Roxgold's Yaramoko permit, where it is continuing.
An excerpt from a July 2010 Technical Report on the Yaramoko Permit provided on
the Roxgold website, describes the mineralization on the Yaramoko permit as a
series of subparallel quartz veins hosted in northwest trending shears. A
granodioritic to tonalitic body has intruded the volcanic country rocks, and the
resulting veins and shears related to this event cut both the volcanics and the
intrusive on its eastern flank. Artisanal workings generally line up along this
south southeast trending shearing, with these activities being conducted at a
high angle to the shear. An interpretation of this description suggests that the
mineralized structures may trend easterly onto the Pompoi permit, although
readers are cautioned that there is no data to confirm that mineralization on
the Yaramoko permit extends onto the Pompoi permit.
According to Roxgold's news releases dated October 4 and 19, 2011, diamond
drilling on the "55 Zone", Bagassi Central area, 2.9 kilometres from Goldrush's
Pompoi permit western boundary, produced gold intersections of 53.56 g/t Au over
8 metres in hole YRM-11-DDH-021, 47.41 g/t Au over 8.5 metres in hole
YRM-11-DDH-018, and 37.68 g/t Au over 16 metres in hole YMR-11-DDH-024. Deeper
holes drilled on the eastern edge of the 55 Zone encountered 31.90 g/t Au over 5
metres in hole YRM-11-DDH-032 and 48.46 g/t Au over 2 metres in hole
YRM-11-DDH-034. Roxgold's interpretation of the drilling results has the series
of gold-bearing structures from north to south occasionally overlapping along
strike in an east to west direction, and perhaps plunging to the east towards
the Goldrush permit.
Goldrush's widely spaced sampling has also documented eight separate anomalies,
each of which is composed of two contiguous samples that could represent
elevated bedrock gold mineralization with strike lengths of up to 800 metres.
Also, a single soil sample assaying 903 ppb gold was found adjacent to the
Pompoi-Yaramoko permit boundary, approximately 700 metres north of Goldrush's
southwest gold-in-soil anomaly.
In addition to the potential extensions of the easterly trending structures
containing the Bagassi Central gold mineralization on the Yaramoko permit, an
interpretation of the regional airborne magnetometer survey which covers the
Pompoi permit suggests the occurrence of a structural regime of northeasterly
trending faults and/or shear zones and folding (in the northern parts of the
permit) similar to that seen at Semafo Inc.'s Mana Mine.
Also, Goldrush has identified in the northern part of the soil sampled area a
northerly oriented gold anomaly that spans a north-south distance of 2,000
metres and an east-west distance of 1,400 metres, with the most westerly portion
approximately two kilometres east of the common Pompoi-Yaramoko permit boundary.
This anomaly is slated for drill testing in a future program.

Quality Assurance/Quality Control
Goldrush maintains a rigorous quality control program involving the use of
certified standards from an accredited Canadian laboratory, inserted blanks, and
the use of repeat assays. Details of Goldrush's quality control program were
provided in the Company's News Release #13 - 2010, dated October 25, 2010.
The SGS laboratory in Ouagadougou, Burkina Faso was used for sample analysis.
Samples are assayed using standard fire assay techniques on a 50 gram charge
with an atomic absorption finish. For its internal control, SGS inserted one
certified standard and one blank, and analyzed one random duplicate for
approximately each 20 samples submitted. For its certified standard and blank
samples included in the QA-QC procedure, Goldrush averaged 4.2% of the total
samples submitted.
The RAB drilling was contracted to Forages Technic-Eau/Burkina sarl based in
Ouagadougou, Burkina Faso.
