Riverstone Resources Inc. (TSX VENTURE:RVS)(OTCQX:RVREF)(FRANKFURT:3RV)
("Riverstone" or the "Company") is pleased to report results from seven diamond
core drill holes on the 90% owned Goulagou II Deposit (the "GGII"), which forms
part of the Company's flagship Karma Gold Project in Burkina Faso, West Africa
(the "Karma Project"). These holes are part of a program of drilling designed to
extend two high-grade "shoots" of mineralization along strike and to depth. (See
Map on the Riverstone Website for the location of the holes:
http://www.riverstoneresources.com/i/maps/GGIIlocationmap_July5.jpg).
Significant assay intervals in these core holes include:
-- 2.83 g/t Au over 84 m including 4.06 g/t over 22 m and including 3.82
over 28 m in DD-12-077
-- 3.97 g/t Au over 20 m and 7.18 g/t over 4 m in DD-12-073
-- 2.41 g/t Au over 40 m and 2.83 over 10 m in DD-12-058
-- 2.78 g/t Au over 20 m and 1.65 g/t Au over 18 m in DD-12-080
-- 2.41 g/t Au over 46.75 m including 3.43 g/t over 24.75 m in DD-12-081
Mineralization at GGII extends over 2,500 metres east-west and to as much as 250
metres in depth in localized areas of deeper drilling. These drill holes have
extended the high grade mineralization from previously drilled holes down dip
from 40 to 140 metres and along strike from 50 to 100 metres. These high grade
mineralized shoots are open along strike in both directions and to depth as is
the entire deposit. Previously drilled holes in these high grade mineralized
shoots returned several good grade intersections, including 4.3 g/t Au over 41
m, 3.6 g/t Au over 18 m, and 2.45 g/t Au over 26 m. These holes are listed in
the NI 43-101 Technical Report titled "Technical Report and Resource Estimate on
the Karma Project, Burkina Faso, West Africa" filed on SEDAR (www.sedar.com)
February 23, 2012.
"We are very encouraged with these assays from drilling at GGII as the property
consistently continues to intersect high grade gold intersections," commented
Dwayne L. Melrose, President and CEO of Riverstone. "We are continuing to expand
the size of these higher grade gold mineralized shoots which will be included in
the upcoming resource estimate schedule for September 2012. The Preliminary
Economic Assessment that is currently being conducted is progressing on schedule
and is expected to be released in August 2012."

The 90% owned GGII deposit is part of the Company's Karma Project which
comprises a NI 43-101 compliant in-pit Whittle indicated resource of 1.6 million
ounces of gold in 47.3 million tonnes grading 1.1 g/t gold and an inferred
resource of 0.6 million ounces of gold in 18.9 million tonnes grading 0.93 g/t
gold (see news release dated January 9. 2012 and NI 43-101 Technical Report
titled "Technical Report and Resource Estimate on the Karma Project, Burkina
Faso, West Africa" filed on SEDAR (www.sedar.com) February 23, 2012.) Since the
data cut-off for the resource estimation, the Company has already completed
+85,000 metres of drilling on the Karma Project. It is expected that the results
of this drilling will add to the overall resources of the Karma Project
deposits.
Riverstone maintains a quality control program involving the use of repeat
assays, inserted blanks and the use of certified standards from an accredited
Canadian laboratory. All samples were prepared at the independent Abilab Burkina
SARL laboratory in Ouagadougou, Burkina Faso, (part of the ALS Chemex Group),
and assayed using standard fire assay with an atomic absorption finish, with
samples grading over one gram per tonne gold re-assayed with a gravimetric
finish, either in Burkina Faso or at the ALS Chemex facility in North Vancouver,
British Columbia, Canada.
Riverstone is active in Burkina Faso, West Africa, where it holds a portfolio of
four high quality exploration projects covering in excess of 2,000 square
kilometres. Addition information about the Company and its activities may be
found on the Company's website at www.riverstoneresources.com and under the

uncertainties relating to the interpretation of drill results and the estimation
of mineral resources, the geology, grade and continuity of mineral deposits, the
possibility that future exploration, development results will not be consistent
with the Company's expectations, accidents, equipment breakdowns, risk of
undiscovered, title defects and surface access, labour disputes, the potential
for delays in exploration activities, the potential for unexpected costs and
expenses, commodity price fluctuations, currency fluctuations, and other risks

Forward-looking information is based on various assumptions including, without
limitation, the expectations and beliefs of management, the assumed long term
price of gold, that the Company will receive required permits and access to
surface rights, that the Company can access financing, appropriate equipment and
sufficient labour and that the political environment within Burkina Faso will
continue to support the development of environmentally safe mining projects.
Should one or more of these risks and uncertainties materialize, or should
underlying assumptions prove incorrect, actual results may vary materially from
those described in forward-looking statements. Accordingly, readers are advised
