Riverstone Provides Update on Liguidi Malguem Permit, Burkina Faso

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/06/12 -- Riverstone Resources Inc. (TSX VENTURE: RVS)(OTCQX: RVREF)(FRANKFURT: 3RV) ('Riverstone' or the 'Company') is pleased to announce, that further to an agreement with Orex Resources Sarl ('Orex'), pursuant to which Orex agreed to file the necessary documents to transfer the Liguidi Malguem exploration permit (the 'Liguidi Permit') to Riverstone (see News Release dated November 28, 2011), Orex has now completed the payment of permit renewal fees, as required by the Burkina Faso, Ministry of Mines, Quarries and Energy, for the Liguidi Permit.

'The payment of the renewal fees is the next step in acquiring the Liguidi Permit for Riverstone and represents a major milestone,' commented Dwayne L. Melrose, President and COO of Riverstone. 'The Liguidi Permit is a highly prospective exploration property with a significant gold in soil anomaly which is +15 kilometres in length which corresponds with numerous artisanal gold sites and mapped structural zones. Riverstone plans to spend a minimum of one million dollars on exploration on the property in 2012.'

When the transfer is complete, the Liguidi Permit will add tremendous exploration potential to the Company's portfolio of properties. The Company's flagship Karma Project has a recently updated NI 43-101 compliant resource estimate prepared by P&E Mining Consultants Ltd. ('P&E') of Brampton, Ontario, which increased, by 42%, the overall global mineral inventory (approximately 800,000 Oz Au) on the Karma Project (see News Release dated January 9, 2012). The estimate was completed on the five deposits that make up the Karma Project Goulagou I, Goulagou II, Kao, Rambo and Nami, which are all in close proximity to each other.

HIGHLIGHTS (resources are contained within five Whittle open pit shells)

--  Global Mineral Inventory (inside and outside of Whittle pit shells)
    consists of Indicated gold mineralization totaling 1,773,000 ounces of
    gold in 54.1 Mt at an average grade of 1.02 g/t Au and Inferred gold
    mineralization totaling 959,000 ounces of gold in 37.4 Mt at an average
    grade of 0.8 g/t Au.
--  Total Indicated gold resources within five Whittle pits are 1,634,000
    ounces of gold in 47.34 Mt at an average grade of 1.07 g/t Au.
--  Total Inferred gold resources within five Whittle pits are 566,000
    ounces of gold in 18.93 Mt at an average grade of 0.93 g/t Au.
--  74% of the resources within the Whittle pit shells are classified as
    Indicated gold resources.
--  This resource will be used as the basis for proceeding with a
    Preliminary Economic Assessment (PEA) commencing in Q1, 2012.

Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category.
