The LAC DE LA LAMENTA- TION Block is composed of 172 contiguous map-staked mining cells (claims) for a total area of 94 sq.km (9434 hectares). A 2003 reconnaissance heavy mineral sampling (by independent geologists and prospectors) yielded kimberlite indicator minerals (KIMs) that sparked the map-staking of the present claims. In 2004-2006, prospecting and further heavy mineral sampling were carried out on this Block. In 2007-2008, a 24-holes drilling program totaling 2381m was completed (THIS REPORT). PROPERTY OVERLOOK The Lac de la Lamentation of the CHIBOUKI project is located in Northern Quebec, James Bay territory, about 100 km northeast of Chibougamau (Fig.!). This land is classified as Class-II according to the James Bay Agreement and does not carry any restriction concerning mining or exploration activities The property is accessible through the all-season 167 gravel road and is located about 110 km NE of Chibougamau. Several gravel logging roads are present in the region and the Tournemine and Clavernie camps of Chantier Chibougamau are located respectively 15km south and 70km south of the Temiscami River. Most of the Lac de la Lamentation Block is accessible by helicopter. Several logging roads (Chantier Chibougamau) are also present in the 32iO4, 32i 11, 32i12 and (specially) 32i05-06 NTS sheets. The LAC DE LA LAMENTATION Block of the Chibouki property is composed of 172 contiguous map-staked claims totaling 94 square kilometers (Fig.2). All claims are located within the 321/04-05-06-11-12 map sheets. All claims were map-staked according to the Quebec's mining Act, and properly filed and attributed. Such holding is not challengeable by a third party, and valid for a period of two years and renewable. In 2003, the project was initially generate by "Le Groupe" composed of Pietro Costa, Robert Gagnon, Michel Gaudreault, Gervais Simard and Daniel Verreault who carried CHIBOUKI-Assessment work report- DIOS EXPLORATION INC. 3 out a reconnaissance heavy mineral sampling program totalling 65 samples. This project was later subject to an option with DIOS Exploration Inc., which paid for the processing of selected fluvio-glacial samples, map-staking of the property, and additional follow-up sampling. The "group" retains a 1% NSR (GOR) that can be bought back for 1000 000$. REGIONAL AND LOCAL GEOLOGY The region is located at the southeastern limit of the Superior craton, along which is located the Chibougamau-Matagami greenstonebelt. It was mapped at the scale of 1:1000 000 by the Quebec government (Hocq, 1985; figure 3). In Chibougamau, the greenstonebelt is divided in 2 main groups: the Roy Group composed of 2 volcanic cycles (mafic to felsic) and the Opemisca Group (mainly sediments with minor potassic volcanics). The Obatogamau and Waconichi Fms correspond to the first volcanic cycle, and the Gilman and Blondeau Fms to the second one. Numereous E-W oriented isoclinal folding and a well-developped associated shistosity are present. Domes and basins interference pattern is the result of two deformation phases. The northeastern portion of the region is overlain by the Proterozoic Mistassini sedimentary basin composed of the Albanel Fm (dolostones and graphitic shales) and the Chibougamau Fm (conglomerates, sandstones, and argillites). The whole region is intruded by mafic intrusions as the Lac Dore Complex and the Cummings sills. To the east, the Grenville Front limits the Chibougamau-Matagami greenstone-belt by _ several extensive NNE-SSW faults (ex: Mistassini, du Chef, Petite-Meule Faults). This sector of the Grenville Front is dominated by biotite-hornblende quartzo-feldspar -- gneisses. Federal and provincial airborne magnetic data outlines an important NE-SW diabase dyke (as well as several minor ones) that is part of the Otish Swarm (1730 Ma). The Mistissini Block geology is dominated by mafic volcanics and clastic sediments in its SW part, and by granitic to granodioritic intrusive at the contact between the Superior and the Grenville provinces (Hocq, 1983) in its NE part. The Lamentation Block geology is mainly composed of granitic to dioritic gneiss injected by minor pegmatitic to mafic-ultramafic intrusions and dykes. The pink pegmatite -- dykelets —dykes are the most common and they are often magnetic. Numereous mafic- _ ultramafic (amphibolized gabbro to pyroxenite) intrusions have circular magnetic signature similar to the ones of kimberlite pipes. 1 1 l L 1 1 I I 1 f -- ~ Ungava Bev Hudson Bay ~ 33 Carats James Bay Hotish Extension ONTARIO % ' Attawatiiskat /i QUEBEC Mis" "sisâ Hotish Désmaraisville Legend Pontax Archean craton 1 Chibouki ir Kirkland Lake f Sedimentary cover Recent mobile ./ emiscaming belts .Kimberlite (s) Atlantic Lake Ellen Ocean "mec Structural zone Kapuskasing DIOS EXPLORATION INC.

Limited work for diamond was carried out in the 1993-94 (Diabex and Diabior), as well as informal esker sampling by BHP and De Beers, but most of the area exploration effort was focused on gold and copper within the Chibougamau greenstone-belt. The property is characterized by the following favorable elements for diamond exploration (Figure 5): 1. Underlying Archean (2,7-2,8 b.y.) Superior craton. 2. Presence of the NNE Mistassini-Lemoyne Corridor that extends itself over 650 km and hosts Beaver Lake- Renards-Tichegami kimberlites, Niaux and Temiscamie nepheline syenites as well as the Castignon lake and Lemoyne carbonatites. 3. Junction of N-S and NNW-SSE Mistassini and NE-SW Preissac mafic dykes swarms. 4. The project is located 20 kilometers southeast from the Portage cluster, 30 km north-northeast of the Otish cluster, and 500 km east of the Wemindji kimberlitic dyke cluster. 5. Proximity to the zone where seismic topography suggests the minimal 200 km depth required for the formation and preservation of diamond. The fertility of this lithosphere keel was proven by the chemistry of Wemindji, Eastmain and Otish regions. 6. Under-explored (for diamond) area. I I !
