Riverstone Resources Inc. (TSX VENTURE:RVS)(OTCQX:RVREF)(FRANKFURT:3RV)
("Riverstone" or the "Company") is pleased to report results from seventeen
diamond drill holes on the 100% owned Kao Deposit ("Kao"), 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 in the
north-east extension area of the main Kao deposit, designed to further test the
extension of easterly-dipping mineralization. (See Map on the Riverstone Website
for the location of the holes:
http://www.riverstoneresources.com/i/maps/120911-120713_Kao_PortPlan.JPG).
Significant assay intervals in these core holes include:
-- 2.39 g/t Au over 24 m in DD-12-130
-- 2.22 g/t Au over 16 m including 3.28 g/t over 8 m in DD-12-139
-- 2.10 g/t Au over 12 m in DD-11-069
-- 2.02 g/t Au over 12 m in DD-12-149
-- 31.8 g/t Au over 2 m and 2.42 g/t over 6 m in DD-12-131
-- 1.84 g/t Au over 14 m in DD-12-72
Mineralization at Kao extends over 1,400 metres in a northeast-southwest
direction and at least 900 metres down-dip to the east. These latest drill holes
confirm the continuation of higher grade material along strike to the northwest
and at depth, with the deposit remaining open to the north, south and down the
dip to the east.
"The extension drilling at Kao continues to return higher grades than the
modelled average grade of the deposit," commented Dwayne L. Melrose, President
and CEO of Riverstone. "This is expected to have a positive effect on the
upcoming resource estimate, which is on track for completion in late September
of 2012. The updated resource model has the potential to increase the mine life
or annual gold production that was identified in the recently released PEA
results."

The 100% owned Kao 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. The results of
a Preliminary Economic Assessment have recently been released (see Company news
release dated August 20, 2012), highlighting the Karma Project to be a robust
project.
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, West Africa (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

compliant technical report supporting the PEA, the assumptions set forth in this
news release and in the Company's news releases of January 9, 2012 and August
20, 2012, and risks and 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 and permitting
activities, the potential for unexpected costs and expenses, commodity price
fluctuations, currency fluctuations, political risk and other risks and
uncertainties, including those described under Risk Factors in each management

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
