- Mineralization remains open at depth and along strike at all four of the deposits that comprise the Karma Project.

- Four gold deposits discovered to date, with numerous gold occurrences and artisanal workings not yet drill tested.

- The resource is shallow with 95% above 100 metres in depth.

- Wardrop recommends a $1.375 million two-phase work program on the Karma project comprising metallurgical test work on the Kao deposits and additional drilling on the Kao, Goulagou 1 and Goulagou 2 deposits.



TABLE 1 - SUMMARY OF KARMA RESOURCE(1)

----------------------------------------------------------------------
Tonnage Grade Contained Gold
Category (million tonnes) (g/t Au) (ounces)
----------------------------------------------------------------------
INDICATED 21.4 1.20 820,500
INFERRED 12.2 0.82 320,300
----------------------------------------------------------------------
(1) Resources are reported at a cut-off of 0.3g/t for oxide and 0.5g/t
for fresh rock Ounces are calculated assuming 100% recoveries.


The Karma Project consists of four separate deposits - Kao, Rambo, GG1 and GG2. The GG1 and GG2 deposits are 8 kilometres west of Rambo, and Kao is 7 kilometres south of Rambo, allowing the company to envision the establishment of a central processing facility (To see Figure 1 please click on the following link: http://media3.marketwire.com/docs/Figure1RVS.jpg). In addition, there are numerous other gold occurrences and artisanal workings in the immediate vicinity of each of the deposits which require evaluation. The Kao deposit, in particular, has demonstrable potential to significantly increase in size based on RAB drilling results and adjacent gold-in-soil geochemical anomalies.

The Company is currently planning a work program for the balance of 2009 comprising both RAB and RC drilling with the objective of expanding the current resource.

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 2,610 square kilometres.
