Porphyry type gold target: DIOS 33 CARATS SOUTH

A rare diamond opportunity : 33 CARATS NORTH

Discovery of Porphyry Gold Tonalite hosted within a nosefold of volcanic rocks on wholly-owned 33 CARATS diamond-gold project, adjacent to the Eastmain Resources Eastmain gold mine deposit and the Stornoway Renard advanced diamond project, Otish region, Quebec. A road currently reaches the gold interest area.

33 Carats gold summary report

The southern part of the 33 CARATS property is overlying part of the Eastmain greenstone volcanic belt, hosting the Eastmain gold mine (in operation in the nineties).  Advanced glacial studies completed by DIOS over the years outlined a 15-20 km x 3-5 km well-structured gold north-east anomalous dispersal train. First till assays include 0.519, 0.583, 1.165, 2.090 g/t Au (all from heavy mineral concentrates).The head source of this gold dispersal train is pointing out towards the volcanic belt wrapping around a tonalitic complex on DIOS ground.  It shows a lot of similarities with the gold dispersal train recently discovered on the AU33 project optioned to Osisko Mining Corporation a few hundreds kilometres more to the west in the lower Eastmain River Area.  DIOS is looking forward to develop the now road accessible 33 CARATS GOLD PROJECT alone or through partnership.

Dios 2011 gold program:

For the first time, gold is discovered in rocks on 33 CARATS diamond project of DIOS EXPLORATION, Upper Eastmain River area, Quebec, within targeted tonalitic intrusive rocks: six samples returned values of gold, silver and copper up to 3.18 g/t, 18 g/t and 1.22%, respectively. Detailed geological mapping outlined a 2 by 6 km tonalitic phase specifically targeted for its gold potential in the western part of a felsic pluton around which is wrapped the Eastmain Greenstone Belt. The mineralized (1-2% pyrite) sicilified tonalite glacial float samples were collected up-ice of a glacial gold train in till. Boulders are angular and their sizes suggest an outcrop source within 2 km, where tonalite was mapped, so not in the eastern part of the property where granodiorite was mapped.

Gold mineralization in these tonalite boulders correlates with significant values of copper and silver, and related values in bismuth, indicative of porphyry type deposits. An anomalous gold bearing outcrop was also discovered, with high exploration potential in its surrounding one km or more radius. DIOS considers these results very significant as it indicates this part of the eastern Eastmain volcanic belt hosts a potential for copper-gold porphyry deposits related to the synvolcanic Lac Erasme pluton. The Otish road towards Renard diamond deposit will go through DIOS’ property, 1-2 kilometres east of the main gold potential area.

Siliceous and biotitic alteration affects most samples. Carbonatation is sometimes observed. Mineralization consists of disseminated pyrite, chalchopyrite and malachite within rocks but also in rusty quartz veins. Sulphide content varies between traces and 5%. Mineralization and alteration types combined with the important till gold train suggest a real potential for a large copper-gold porphyry system that could be the source of the gold-bearing boulders found during the 2011 campaign.

DIOS 33 CARATS NORTH ; A Rare Diamond Opportunity Last summer, the 33 CARATS DIAMOND EXPLORATION PROGRAM consisted in the surface prospecting of some 95 geophysical targets for diamondiferous kimberlite outlined by an independent geophysicist from processing several detailed geophysical surveys, following results from indicator mineral sampling campaigns over the years. These targets were mainly located on the new blocks designated last winter that are adjacent (10-20 km) to Stornoway Renard diamond deposit property. On each target, the immediate vicinity (100-200 m diameter) of the center of the anomaly was prospected for outcrops, as well as the down-ice area (500-1000 m) for possible glacial floats. Twelve (12) of the checked anomalies were explained by the occurrence of magnetic granite outcrops and therefore eliminated as potential drill targets.  A selection among the best remaining targets should be eventually drilled later this year.
