Goldrush Resources Ltd. (TSX VENTURE:GOD)(OTCQX:GDRRF) ("Goldrush" or the
"Company") is pleased to report the results, including high grade
mineralization, from five reverse circulation ("RC") holes of a 98 hole RC and
18 hole diamond drilling fill-in program on the Company's Ronguen Gold Deposit
in Burkina Faso, West Africa. Highlights include:
-- 8.77 g/t Au over 23 metres, including 128 g/t Au over 1 metre (4.51 g/t
Au over 23 metres when cut to 30 g/t Au), and 1.19 g/t Au over 12 metres
in hole KGRR11-228
-- 8.34 g/t Au over 6 metres and 0.66 g/t Au over 12 metres in hole KGRR11-
251
-- 2.53 g/t Au over 6 metres and 2.33 g/t Au over 6 metres in hole KGRR11-
229
-- 0.64 g/t Au over 23 metres and 2.04 g/t Au over 5 metres in hole KGRR11-
252
Hole KGRR11-228 was collared on line 780E of the western G2 grid of the Ronguen
deposit, in an 80 m gap between existing drill sections. Hole KGRR11-229 was
drilled 25 metres to the north of -228 and hole KGRR11-230 was drilled 50 metres
to the north of -228, all on section 780E. In addition, Goldrush drilled RC
holes KGRR11-251 and -252, 20 metres to the west and east, respectively, of hole
- 228, and then followed up with core hole KGRC11-042 collared 25 metres to the
south of hole -228 to test the down-dip potential of this high grade gold
intercept. Assays from core hole -042 have not been received.
These results are consistent with the previously drilled sections 40 metres to
the east and 40 metres to the west which show the presence of an upper
mineralized zone extending to surface at about grid station 115N and with a
second mineralized zone underlying the upper zone that represents a lens that
does not extend all the way to surface. However, the previous drilling
intersected grades more typical of the Ronguen mineralization (in the order of
1-2 g Au/t). During interpretation of this area, special attention will be given
to the precise location of north northwest trending cross structures which may
control higher grades along ore shoots that follow the intersection of the main
zone and the cross structures.
Commenting on the assay results, Len Brownlie, President and CEO of Goldrush
said, "The intersection in hole KGRR11-228 is the highest grade we have
encountered in the Ronguen deposit to date. Intersections of this grade are
unusual, and we are evaluating the controls of high grade intersections such as
this because of the implications for future production at Ronguen. This most
recent fill-in drilling program of new sections between the widely spaced 80
metre drill sections is providing for a more robust interpretation of the
structure of the deposit and the correlation of higher grade zones. We are
pleased with the overall results of our fill-in drilling program, and are
looking forward to receiving the results of our new resource estimate to be
prepared by SRK Consulting during the first quarter of 2012."

(1) "Vertical depth" is the calculated depth to the centre of the
intersection.
(2) True widths are determined to be 90 to 95% of core intervals.
(3) All holes were drilled at an azimuth of 24 degrees and inclination of
-60 degrees.
(i) Open at the end of the hole.
(ii) Cut-off grade of 0.5 g/t Au; no top cut applied to exploration
drilling results.

Ronguen Exploration Plan
A total of 98 RC holes totaling 7,793 metres and 18 core holes totaling 2,347
metres were completed in the fall 2011 drill program on the Ronguen gold
deposit. A total of 1,325 metres of surface trenching in 13 trenches are
currently near completion. Samples from the remaining 35 RC and 18 core holes
have been delivered to the assay lab and results will be announced when
received. Following receipt of all assays, results will be interpreted and
incorporated into a three-dimensional model in preparation for the updated
resource estimate.
Ronguen Deposit Mineralization
The Ronguen gold deposit is located within the northeastern part of the highly
prospective Birimian age Boromo greenstone belt in Burkina Faso. The local
geology at Ronguen is dominated by an east northeast ("ENE") trending
metasedimentary sequence consisting of interlayered siltstone, mudstone and
minor conglomerates that are intruded by plugs, and narrow dykes and sills of
gabbroic composition. The Ronguen mineralized zone is located in the structural
hanging wall of a major ENE thrust fault which recorded a tectonic transport
direction towards the north. The mineralized deformation corridor represents a
major ENE trending high angle reverse fault zone, dipping moderately to steeply
towards the south. Gold mineralization is found in both metasedimentary and
mafic intrusive rock; there are no obvious lithological controls yet recognized
at this epigenetic gold deposit. The gold mineralization is associated with
quartz-carbonate veins/veinlets and with sulphides occurring as disseminations
and patches, and in veinlets. Two sets of gold-bearing quartz veins are
developed: subvertical shear veins parallel to the shear zone foliation and to
the shear zone boundaries, and subhorizontal extension veins. Small quartz
stockworks are present and represent a part of the gold mineralization.
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 #2010-13, 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 two
certified standards and one blank, and analyzed one random duplicate for
approximately each 25 samples submitted. For its certified standard and blank
samples included in the QA-QC procedure, Goldrush averaged 11.0% of the total
samples submitted.
The RC drilling was contracted to Forages Technic-Eau/Burkina sarl based in
Ouagadougou, Burkina Faso.

About Goldrush: Goldrush is a Canadian mineral exploration company which has
successfully focused on gold exploration in West Africa, where the company has
discovered, and is currently expanding and defining the 249,000 ounce (inferred
resource of 5.9 million tones at a grade of 1.31 g/t Au) Ronguen gold deposit in
Burkina Faso.
About Burkina Faso: Burkina Faso is a politically and economically stable West
African democracy that relies on farming and mining as it primary sources of
foreign exchange. Burkina Faso saw gold production double from 2008 to 2010 and
is currently the fifth largest gold-producing country in Africa. Control Risks,
a global consultancy specializing in political, security and integrity risk,
ranked Burkina Faso #3 in their 2011 World Risk Survey - countries with least
risk. The World Risk Survey asked respondents to rank their perception of risk
in the following categories: financial risk, sovereign risk, land access, green
tape, land claims, red tape, social risk, infrastructure, civil unrest, natural
disasters and labour relations.
