Riverstone Intersects 16.7 g/t Gold (0.49 oz/ton) Over 12 Metres
at Karma
March
10, 2008
Riverstone
Resources Inc. (TSXV: RVS, Frankfurt: 3RV)
is pleased to report a second round of results from the fourth phase of
reverse circulation ("RC") drilling recently completed on the
Kao Main Zone at its Karma project in Burkina Faso, West Africa. Highlights
include 16.7 g/t gold over 12 m, 2.22 g/t gold over 14 m, 1.18 g/t gold
over 26 m, and 1.28 g/t gold over 20 m. The Kao Main Zone continues
to expand to the northwest, and it is still open to the north and to the
northwest and at depth. (See attached Map)
"We are very excited about the discovery of this exceptionally high
grade gold zone within the Kao Main Zone", commented Michael D.
McInnis, President of Riverstone. "High grade feeder zones are
common within West African gold deposits and our expectation is that we
will continue to encounter more of these higher gold values".
This current phase of RC drilling comprised 5,050 metres in 50 holes,
most of which was designed to determine further extensions of the shallow
oxide gold mineralization at the Kao Main Zone in preparation for an
independent resource estimate. Results from holes 100 to 118 were
previously reported (see News Release dated February 28, 2008).
Significant results from holes 120 to 137 are summarized in the table
below. All holes were drilled at -60º. Intervals reported are
drilled intercepts, which may not represent true widths of the
mineralized zones. Additional results will be released once assays have
been finalized and verified.

The Company is presently drilling on the adjacent Goulagou permit which
contains a NI 43-101 compliant indicated resource of 280,000 ounces of
gold at a grade of 1.70 g/t and a further inferred resource of 270,000
ounces of gold at a grade of 1.49 g/t (see News Release dated October 11,
2007). Kao and Goulagou are two of the four contiguous exploration
permits included in the Company's Karma project, the others being Rambo
and Rounga. The Kao Main Zone and Goulagou deposits are
approximately 12 kilometres apart, separated by flat terrain. A
third Company-owned deposit at Rambo lies essentially midway between the
Kao and Goulagou deposits.

The Company maintains a rigorous quality control program involving the
use of repeat assays, check assays at independent labs, inserted blanks,
and the use of verifiable standards from an accredited Canadian
laboratory. All RC samples were assayed using standard fire assay
with atomic absorption techniques, with samples grading in excess of 2.00
g/t gold re-assayed with a gravimetric finish, at the independent Abilab
Burkina SARL laboratories in Ouagadougou, Burkina Faso, which is part of
the ALS Chemex group.
Riverstone Resources Inc. is active in gold exploration in Burkina Faso,
West Africa, where the company holds an extensive portfolio of high
quality exploration permits covering 3,500 square kilometres. For

events or results to differ from those reflected in the forward-looking
statements, including, without limitation, 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, title matters and surface access, labour disputes, the
potential for delays in exploration activities, the potential for
unexpected costs and expenses, commodity price fluctuations, currency
fluctuations, failure to obtain adequate financing on a timely basis and
other risks and uncertainties, including those described under Risk
Factors in each management discussion and analysis. In addition,
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 not to place undue reliance on forward-looking statements.
