Riverstone Starts Drilling on Liguidi Permit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 27, 2012) - Riverstone Resources Inc. (TSX VENTURE:RVS)(OTCQX:RVREF)(FRANKFURT:3RV) ("Riverstone" or the "Company") is pleased to announce the start of a Reverse Circulation ("RC") drilling program on its 100% owned Liguidi Malguem Exploration Permit ("Liguidi") in Burkina Faso, West Africa. The RC drill program is intended to follow up on a recently completed Rotary Air Blast ("RAB") drilling program that tested portions of a 13 km long by up to 4 km wide soil geochemical anomaly. This soil anomaly represents one of the largest and strongest continuously mineralized gold anomalies in Burkina Faso.

The Liguidi property contains several distinct artisanal sites within the soil anomaly, which is characterized by highly anomalous gold values in excess of 100 ppb gold, and which is open to the southwest. It is approximately 4 kilometres to the property boundary. The soil anomaly closely follows a strong deformation zone, thought to represent a splay off of the Markoye Fault Zone. The Markoye Fault Zone and associated structures hosts in excess of 15 million ounces of gold in Burkina Faso alone.

From northeast to southwest, the artisanal sites are Wayalguin, Three Hills, the Quartz Zone and Legare's Zone. The Quartz Zone is a strong 1000 m by 150 m zone of anomalous quartz-sulphide boulders that graded greater than 1.0 g/t gold that was confirmed with RAB drilling. Legare's Zone is a 6 km long trend of gold mineralization, with a parallel 2 km long zones to the southeast, which were also confirmed with RAB drilling. Previous results include (see Riverstone news releases dated September 18, 2012 and September 20, 2012):

Trench ("TR") or Interval Average Gold Location
Drill Hole (m) Grade (g/t)
TR-01 8 2.18 Wayalguin
RC-07 4.5 1.66 Wayalguin
TR-04 111 0.63 Three Hills
including 18 1.45
and 18 1.53

including 12 2.78

LMG-12-RAB-864 6 1.98 Legare's Zone
LMG-12-RAB-869 12 1.28 Legare's Zone

"We are excited about the start of the RC drill program. The recently completed RAB drilling program confirms that the 13 km long soil geochemical anomaly hosts significant gold grades throughout its strike length", commented Dwayne L. Melrose, President and CEO of Riverstone. "The RC drilling program is expected to build on the previous RAB results along the Markoye Fault Zone that hosts the greatest concentration of gold resources delineated to date in Burkina Faso".

About Riverstone

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 km. Riverstone's flagship project is the Karma Gold Project in Burkina Faso, West Africa (the "Karma Project"), which comprises a NI 43-101 compliant in-pit Whittle total indicated resources of approximately 1.9 million ounces of gold in 56.5 million tonnes with an average grade of 1.07 g/t gold and total inferred resources of approximately 492 thousand ounces of gold in 15.4 million tonnes with an average grade of 1.0 g/t gold (see Riverstone's news release dated October 3, 2012 and independent NI 43-101 compliant Technical Report titled, "Technical Report and Updated Resource Estimate on the Karma Project, Burkina Faso, West Africa", dated effective October 1, 2012, filed on SEDAR (www.sedar.com) November 7, 2012). The results of an independent Preliminary Economic Assessment ("PEA") (see Riverstone news release dated August 20, 2012 and independent NI 43-101 compliant Technical Report titled, "Preliminary Economic Assessment Report for the Karma Project, Burkina Faso, West Africa", dated effective August 2, 2012, filed on SEDAR (www.sedar.com) September 17, 2012), highlights the Karma Project to have robust economics. The PEA is based on Riverstone's previous January 9, 2012 resource estimate and while relevant and valid in regards of the January 9, 2012 estimate cannot necessarily be extrapolated to the updated resource estimate announced on October 3, 2012.

The PEA is considered preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves and there is no certainty that the production profile concluded in the PEA will be realized. Mineral Resources that are not Mineral Reserves have not yet demonstrated economic viability.
