The Antino Project is located in southeastern Suriname, South America, close to the border with French Guiana. The project is 220 km south east of Paramaribo, the capital city of Suriname, and 10 km west of the Lawa River, that forms the border with French Guiana.

Alluvial gold was first discovered in the Antino Project area in 1881, and since then there has been continued but intermittent gold mining from alluvials and saprolite. Modern systematic exploration was carried out by Golden Star Resources from 1993 to 1997, focused exclusively on shear hosted mineralisation. Since 1998 small scale mining has continued in the general area. In the southern part of the Antino project, intrusive hosted quartz veins, some hosting very high grade visible gold mineralisation have been exploited on a small scale. The previous exploration work did not adequately assess the potential of the intrusive hosted gold mineralisation. This opportunity is the focus of Reunion Gold's exploration efforts.

Geologically the Antino area lies within the Guiana Shield, which hosts a number of gold deposits such as Omai in Guyana, Rosebel in Suriname and Camp Caiman in French Guiana. The rock package at Antino is typical of the archean proterozoic greenstone belts of the region, and consist of a belt of low grade metavolcanic and metasedimentory rock known as the Marowijne Group, which covers large parts of NE and E Suriname. Gold mineralisation identified in the Antino project area represents two different deposit types, both well documented from greenstone belts in other parts of the world. The first is shear zone hosted and the second is porphyry based.

The upper and lower Antino target areas are related to a prominent shear zone along which there has been significant hydrothermal activity, alteration and mineralisation.

The Maripasula target represents porphyry hosted gold mineralisation comparable to the Omai gold deposit in Guyana.

The importance of intrusive hosted gold at Antino was not previously recognized. Small scale mining has discovered several zones at primary gold mineralisation occurring as a stockwork zones within the quartz diorite intrusive, and as high grade gold within a schist, on the margins of the intrusive. Channel sampling of the small scale working carried out by staff has returned low grade (1-3 g/t) gold within the stockwork mineralisation, and higher grade (13-50g/t) values on the margins. The extent and continuity of both types of mineralisation are as yet unknown, and are the focus of Reunion's exploration efforts.


Initial Targets
The Company first focused on the Maripasula Creek target (Felice and Broko Laka locations) to define and extend mineralized zones previously exploited by artisanal miners. Outstanding quality specimens of visible gold, hosted in quartz veins, were recovered from now abandoned underground workings at Broko Laka.

Exploration Activities
In early 2008, the Company conducted a follow-up drilling program at Antino and carried out a review of all data and assays received to date. Work will continue in 2008 on the promising gold mineralization intercepted within the Upper Antino target to help determine the presence of a raking shoot. ICP analysis will be conducted on samples that cut the shear zone structure.

Interesting assays returned from the south-western corner of the eastern grid prompted the start of an in-fill program in early 2008. A follow-up mapping and sampling effort will occur once the area dries out enough to allow safe access. There remains a number of targets at Antino that will be evaluated, once resources become available.
