Reunion Gold provides further drilling results on its Matthews Ridge Manganese project
LONGUEUIL, CANADA–(Marketwire – June 13, 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 completed a total of 43,444 meters of diamond drilling in 669 holes and 17,361 meters of reverse circulation drilling in 283 shallow holes. There are currently four diamond drill rigs working at the project.
Reunion has to date received complete assay results from 556 drill holes, of which 243 were previously released. Results from 98 diamond drill holes and 215 reverse circulation drill holes completed in 2011 and 2012 are reported in this press release. Manganese mineralisation was intersected in 88% of all drill holes, with most intersections starting from surface outcrops in trenches. Highlights of the most significant assay results are presented in Table 1. Refer to Appendix 1 for complete new results.

The drilling program on all targets between Hills 1 and 9 is expected to be completed at the end of June 2012. The Company will have 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 will be about 50 m by 50 m, thus providing sufficient information on the mineralized bodies for the completion of geological modelling and resource estimation in the second half of 2012. Maps showing the various target hills and location of the drill holes are provided in Appendix 2.
Drilling results to date continue to indicate an excellent correlation with trench intersections, confirming that the mantle mineralization persists regularly in the saprolite zone and continues as proto-ore in the fresh rock.
The trenching and drilling programs are 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 structural information, the drilling program aims at demonstrating the continuity of manganiferrous bodies at depth and their geometry. Drilling is being done to the saprolite-fresh rock interface. The Company intends to define mineable resources only in the saprolitic and residual materials, which is amenable to simple earth-moving extraction.
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 for manganese over an area of 19,770 km2 surrounding the four Prospecting Licences. 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).
The Company has also launched an exploration program at the Pipiani Hills target, some 50 km to the southeast of Matthews Ridge, where Union Carbide Corporation conducted extensive exploration work in the 1960s, including pitting, trenching, two adits and 32 diamond drill holes to define a sequence with manganese mineralization over four kilometers long. Reunion is mapping all previous work and will launch a comprehensive trenching and drilling program to define the geometry and grade of manganese mineralization.
At both Matthews Ridge and Pipiani, manganese mineralization is hosted by the Barama sedimentary sequence of Proterozoic age and consists of typical mantle and residual deposits formed as a result of oxidation and supergene enrichment under an equatorial 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 6-inch casing, sampling at every meter and splitting the rock chips once in the field and processing an entire half sample. Standard reference materials, blanks and duplicate samples have been used to control laboratory accuracy and precision. Core sample preparation was done by Activation Laboratories Ltd. (Actlabs) and ACME Laboratories (ACME) 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 RC samples were done by FILAB Laboratories on site using the same methodology described above.

About the Company
Reunion Gold Corporation is a mineral exploration company focused on the acquisition, exploration and development of mineral properties in the Guyana Shield of South America. The Company through its 100% indirectly owned subsidiary Reunion Manganese Inc., has assembled a large, strategic land position to conduct exploration and development activities for manganese in the North West District of Guyana. The Company also has the right to acquire a 100% interest in a gold exploration project located in the Lely Mountain area in Eastern Suriname.
Manganese is the fourth largest metal consumed in the world, behind iron, aluminum and copper. It is a key component in steel and iron production with no viable substitute, and is in short supply.
