VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 02/13/13 -- Riverstone Resources Inc. (TSX VENTURE: RVS)(OTCQX: RVREF)(FRANKFURT: 3RV) ("Riverstone" or the "Company") reports that 13 of 15 widely spaced reverse circulation ("RC") drill holes designed to test the main 13-kilometre-long target at its 100% owned Liguidi property ("Liguidi") intersected highly anomalous to potentially economically significant bedrock gold mineralization.

Cumulative results to date at Liguidi - from current and previous RC drilling, historic rotary air blast ("RAB") drilling and extensive rock and soil sampling - indicate a widespread, in situ gold system that is one of the most compelling early-stage regional exploration targets in Burkina Faso, West Africa.

Significant gold intercepts from RC drilling in Q4 2012 at Liguidi include:

-- 3.12 g/t gold over 6 m in LMG-RC-022-- 0.77 g/t gold over 18 m in LMG-RC-021-- 1.64 g/t gold over 6 m in LMG-RC-032-- 0.61 g/t gold over 10 m in LMG-RC-025-- 1.54 g/t gold over 4 m in LMG-RC-023



(All intercepts occur within 100 metres of surface.)

"This first-of-its-kind scout drill program gives us confidence in the continuity and strength of this mineralized system and clearly demonstrates that the Liguidi target has excellent potential to contribute significantly to Riverstone's organic growth in 2013 and beyond," said Dwayne Melrose, President and CEO, Riverstone. "Importantly, these drilling results demonstrate that the extensive geochemical gold footprint at Liguidi has an underlying bedrock source and persists from surface down to depths of at least 100 meters. The target is open in all directions, and warrants a comprehensive drilling campaign to identify and delineate the high grade segments of this mineralized structure."

The Liguidi target stretches for at least 13 kilometres along a splay of the Markoye Fault Zone. The Markoye Fault Zone and associated structures transect the country (NNE-SSW) and host estimated resources of more than 16.5 million ounces of gold in Burkina Faso alone(1).

Riverstone plans to undertake a multi-phase drilling campaign at the 225-square-kilometre Liguidi property as part of its 2013 exploration program. Drilling at Liguidi is expected to start by March 2013 after four weeks of detailed mapping and targeting.

The strength and continuity of the Liguidi target increases with each successive drilling and sampling campaign. It is underpinned by a high-intensity gold-in-soil anomaly that stretches for at least 13 kilometres. Limited trenching and drilling carried out in 2005 provided encouraging results, including 0.63 g/t gold over an entire 111-metre trench length, including 18 metres of 1.45 g/t gold and 18 metres of 1.53 g/t gold. Drill results included 16.5 metres of 1.25 g/t gold, including 9 metres of 1.88 g/t gold. In 2008, Riverstone announced a rock-sampling program had returned encouraging results, with values as high as 15.81 g/t gold. Over 20% of the samples ranged between 1.01 g/t and 6.88 g/t gold.

The target was further defined by strong and consistent RAB results released in 2012. Significant intercepts included: 1.43 g/t gold over 24 metres, including 2.78 g/t gold over 12 metres; 1.69 g/t gold over 11 metres; and 1.46 g/t gold over 12 metres.

Ian Cunningham-Dunlop, P. Eng., Senior Vice President Exploration, is the Company's designated Qualified Person for this news release within the meaning of NI 43-101 and has reviewed and verified that the information contained in this release is accurate and approves of the written disclosure of same. The density and spacing of drilling to date does not allow an exact orientation of the zones to be determined, and their true widths are unknown. As a result, there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resource. Samples were assayed by ALS Chemex in Ouagadougou, Burkina Faso. Assays were by Fire Assay with AAS finish and repeats of all AAS assays over 1.0 g/t by Fire Assay with gravimetric finish. Control samples (accredited standards, blanks and duplicate samples at the rig and preparation stage) were inserted on a regular basis every 10 samples. Results were monitored on receipt of assays.
