High Grade Gold Discovery at Osikonmaki Prospect Confirmed and Extended

TORONTO, CANADA--(Marketwire - April 24, 2012) - REBgold Corporation (TSX VENTURE:RBG) ("The Company") is pleased to announce final results from the recently completed drill program at the Osikonmäki East prospect on the Rantasalmi gold property. The most significant hole since the last news release, BELOSI 081, continues to develop and extend the Upper East HW Zone discovered in the 2011 drilling campaign. BELOSI 81 was mineralized almost its entire 205m length with the most significant intercept of 18m averaging 5.7g/t gold within a 35m zone averaging 3.2g/t. This zone has now been intersected by four drill holes whose results are tabulated below, and represents a significant new discovery. The zone, though still requiring further delineation, appears to be steeply dipping to the south and occurs from bedrock surface, has a true thickness of at least 12 metres, a strike of at least 100 m and remains open at depth and along strike. Adjacent to the high grade zone in the hanging wall of the main shear there appears to be a zone of lower grade mineralization, representing potential for a bulk tonnage target.

Table 1: All intersections into Upper East HW zone. Intersections are based on a 0.3 g/t Au cut-off (higher grade intervals at 1.0 g/t Au cut-off) with a grade thickness greater than 2 gram metres. No top cut is applied. Maximum grade is 69.6 g/t Au over 0.67 metres (BELOSI081), one of 20 individual samples over 10 g/t Au (0.32 oz/t). Intersections are estimated to be 70-90% of true width.

Mark Burridge, Chairman, comments, "The latest drilling continues to increase the potential for Osikonmaki East to become a significant gold deposit. Every intersection into the new eastern hanging-wall zone has yielded greater than 100 gram metres, displaying potential for both high grade and bulk tonnage mineralization. There is strong evidence to suggest that the Osikonmaki East deposit extends at depth and along strike. While the Osikonmäki East project has been the focus of recent work, we also remain excited about the overall potential of the Rantasalmi project. Several other target areas, including the historical resources at Osikonmäki West and Pirilä are yet to be tested."

Additional drill hole results not previously announced are published below.

Other drill holes confirmed the depth and western strike potential of the systems. BELOSI 84 was drilled to target the main shear zone at depth on the eastern portion of the shear zone. The hole intersected 9.8m at 0.9g/t and identified additional mineralization in the hanging wall, including 6m at 1.5 g/t.

BELOSI 82 was drilled to test the depth extension of the main shear zone 700 m further to the west, and it confirmed the extension of the shear zone at depth but assay results were modest, at around 0.5g/t. The hole appears to have intersected the low grade zone in-between the higher grade chutes identified in previous holes.

BELOSI 83 and BELOSI 85-91 were shallow exploratory holes drilled to test the shear zone as it continues westwards towards the Osikonmäki West mineralization. The main shear was intersected in all holes but from the limited drilling undertaken, grades appear generally lower in this portion of the shear zone, with individual samples up to 2.75 g/t gold recorded.

Other ongoing work related to the project include: the surveying and QA/QC assaying of historic holes not used in the previous resource estimates. These, combined with the results from this year's drilling program, will form the basis for updating the mineral resource estimate.

Osikonmäki Geology: The Osikonmäki project occurs in a three kilometer long shear complex, hosted by a Proterozoic aged Tonalitic Intrusion. Most of the drilling to date has focused on the eastern 800m of the shear where the mineralization is primarily associated with a 45 °south dipping shear zone between 4 and 30 m thick. A series of higher grade chutes pitch at shallow angles across the plane of the main shear, plunging 20°to the ESE contain the better part of the mineralization and extend for at least 600 m down plunge. These chutes have been grouped into three principle lode systems the S, T and U lode systems. The following resources have been outlined on the Rantasalmi Property to date:

Property Prospect Resource Category Tonnes Au g/t Contained Oz's
Rantasalmi Osikonmäki East Indicated 1,296,000 1.7 68,000
Rantasalmi Osikonmäki East Inferred 3,542,000 2.09 244,000
Rantasalmi Osikonmäki West Historical 90,000 4.86 14,000
Rantasalmi Pirilä Historical 150,000 8.9 43,000

The drilling was undertaken by Drillcon SMOY of Finland, providing 42 mm diameter core. Samples are comprised of half diamond core. Intersections are estimated to be 70-90% of true width. No top cuts are applied with the highest individual assay being 47.8 g/t gold over 0.46 metres. Core samples are sawn in half on site, prepped and assayed by 30g fire assay with an AAS finish at the internationally accredited laboratories of ALS Chemex in Finland. The quality assurance-quality control (QAQC) program of Belvedere consists of the insertion of certified standards of known gold content every 20 samples, with blanks at the beginning of each batch. In addition, ALS Chemex inserts a number of blanks and standards into the analytical process. Standards, blanks and duplicates make up approximately 15% of the samples assayed. The remaining half core is retained on site for verification and reference purposes.

The resources were previously announced in a press release on 11th October, 2011. An NI 43-101 compliant Technical Report "Mineral Resource Estimate of the Rantasalmi Gold Project in Finland" filed on SEDAR October 19th, 2011. The mineral resource estimate for Osikonmäki East was prepared by Golder Associates (UK) Ltd under the supervision of Alexandra Akyurek (CSci, MSc MIMMM), acting as an independent "Qualified Person" as defined by National Instrument 43-101. Mrs Akyurek is a member of the Institute of Materials, Minerals and Mining (Member #447670). The Qualified Person has not done sufficient work to classify the historical estimates at Osikonmäki West and Pirilä as current resources under NI 43-101, and suggests that the historical estimates should be considered an historical reference of tonnes and grade, and not resources. These historical estimates have not been validated by Golder and no reliance should be placed on these figures.
