LONGUEUIL, CANADA--(Marketwire - Aug. 22, 2012) - Reunion Gold Corporation (TSX VENTURE:RGD) ("Reunion or the "Company") is pleased to provide an update on its exploration activities at the Matthews Ridge manganese project in Guyana, South America.

The Company has concluded its planned drilling program, completing a total of 47,570 meters of diamond drilling in 735 holes and 17,361 meters of reverse circulation drilling in 283 holes. The average length of all holes drilled is approximately 60 meters.

Reunion has to date received complete assay results from 571 drill holes, of which 513 were previously released. Results from 54 diamond drill holes and four reverse circulation drill holes done in 2012 are reported in this press release. Reunion expects to receive the balance of the assay results by the end of September 2012.

The drilling program closed the drill hole-spacing between Hill 5 to Hill 9 to nearly 50 m by 25 m centers, while drill hole spacing for Hills 1 to 4 is about 50 m by 50 m, thus providing sufficient information on the mineralized bodies to initiate a resource estimation. The geological database is being delivered to an independent consultant, with the objectives of completing an initial resource estimate and a technical report compliant with Canadian National Instrument 43-101 in the second half of 2012.

Highlights of the most significant assay results are presented in Table 1. Refer to Appendix 1 for complete new results.

Drilling results continue to indicate an excellent correlation with trench intersections, confirming that mineralization persists regularly throughout the saprolite zone and continues as proto-ore in the fresh rock. Maps showing the various target hills and location of mineralized zones in relation to the drill holes are provided in Appendixes 2 and 3.

The trenching and drilling programs were designed both to evaluate the previously mined areas and to define the extent and characteristics of known but unexplored mineralized zones. While trenches allow surface sampling and provide good geological information, the drilling program aims at demonstrating the continuity of manganiferous bodies at depth and their geometry. Drilling has been done to the saprolite-fresh rock interface. The Company intends to define resources only in the saprolitic and detrital materials, which are amenable to simple earth-moving extraction.

Project description

The Matthews Ridge Project consists of four Prospecting Licenses covering an area of 185 km2 located in northwest Guyana, in and around the former Matthews Ridge mine. The Company also holds two Permissions for Geological and Geophysical Surveys ("PGGS") for manganese over an area of 14,970 km2 surrounding the four Prospecting Licences. The Company recently relinquished approximately 25% of the original surface area on the first anniversary of the PGGS in accordance with the terms of the PGGS. Manganese ore was mined from 1960 to 1968 by Union Carbide and exported via railroad and a fluvial port. Mining was done on five of a series of nine hills extending for 15 km and striking northeastern-southwestern (see Appendix 2).

Manganese mineralization is hosted by the Barama Group sedimentary sequence of Proterozoic age and consists of typical mantle and detrital deposits formed as a result of oxidation and supergene enrichment of manganese-rich sediments under a tropical climate. The mantle deposits are formed by manganese oxide and hydroxide minerals occurring along the crest of hills and are related to the weathered profile, reaching 120 m below surface.

Quality assurance and quality control

Diamond drilling was done using HQ-diameter casing and triple-tube technology to maximize recovery. Half of the core was used for sampling at regular 1.5 m intervals. Reverse circulation drilling was done with six-inch casing, sampling at every meter and splitting the rock chips once in the field and processing an entire half sample. Standard reference materials, internal standards, blanks and duplicate samples have been used to control laboratory accuracy and precision. Core sample preparation was done by Activation Laboratories Ltd. and ACME Laboratories at their facilities in Georgetown, comprised of crushing to minus 2 mm and pulverization passing 200 mesh, followed by XRF assays for manganese and other relevant oxides at their laboratories in Canada. Sample preparation and XRF assay of reverse circulation drill samples were done by FILAB Guyana Laboratories on site using the same methodology described above.

Carlos H. Bertoni, P. Geo., a qualified person as defined under the terms of NI 43-101, has verified the data and approved the technical information contained in this press release.
