Wemindji Diamond Project
UTM Zone 17
NTS 33C-D-E-F & 32D/01
Ownership
Globex Mining Enterprises Inc. and its partners Aurogin Resources Ltd. and Sparton Resources Inc. have acquired 100% interest in 616 cells (map designated claims) covering 35,657 hectares (approximately 88,108 acres) in the Wemindji area of northwestern Quebec, east of James Bay. The cells were within UTM Zone 17, NTS 33D-C-E-F.
In early 2003, Globex, Aurogin and Sparton optioned the claims to a third party and each retained a 1% Net Diamond Royalty as well as a 1% Net Smelter Royalty on all minerals other than diamonds. Work since 2003 has caused the property to be reduced to 97 cells totalling 4,958.7 hectares which have exploration potential for diamonds and gold.
Regional geology
The rocks underlying the proposed survey block are Archean in age and belong to the western extension of the La Grande structural sub-province. The La Grande sub-province is a volcano-plutonic belt, composed of 30% gneiss, 10% volcano-sedimentary rocks and 60% granitic plutonic rocks with mafic and ultramafic dykes. Very little geological mapping has occurred in the region since the original work by Remick in 1976 (DP 446).
Structural
There are 3 kimberlite localizing structures intersecting in the Wemindji sector of James Bay Quebec. They are: 1) the Winisk River fault extension in Ontario that becomes the Sakami graben in Quebec; 2) Kapuskasing structural zone; and 3) the Otish lineaments.
-
Kimberlites of the Attawapiskat area are located where the Winisk River fault splays to the East and North, slightly SE of a NE trending Proterozoic diabase dyke.
The Winisk River fault continues its East and Northward migration forming an arcuate, approximately E-W structure and ends up as the Sakami graben in Quebec. This East and Northward arcuate structural pattern is also observed separating the Bienville - La Grande and the Minto - Bienville sub-provinces. The Winisk River fault itself separates the Sachigo and Winisk sub-provinces.
-
The Kapuskasing structural zone extends from south of Lake Superior in the United States, across Ontario, Quebec and up to the Torngat region in the Ungava district.
The Kapuskasing structural zone has both kimberlite and diamond occurrences along its length in Ontario and in the United States, but remains virtually untested in Quebec. Diamond exploration activity is ongoing on the Kapuskasing structure in particular in the Torngat region of Quebec.

Points of interest
All three of these regional possibly diamondiferous kimberlite localizing structures (Winisk River extension/Sakami graben, Kapuskasing structural zone and the Otish lineament), intersect in the vicinity of Wemindji.
In the Attawapiskat area, a third structural element is also involved. It is the Nottaway River - Saguenay Zone.
It is interesting to note that chromium deposits are located on the combined lineaments of Winisk River extension/Sakami graben in both Ontario and Quebec. They are in Ontario, the Bib Trout Lake deposit and in Quebec, the Pro-Or showings. On the Quebec side of the structure, there are also alkaline intrusions. Both chromium deposits and alkaline intrusions are indicative of deep structural breaks as are kimberlites.
Several linear geophysical structures are seen to parallel these diamondiferous structures just south of Wemindji in 33D/15, 16.
History
There is no record of significant exploration in the area of the properties.
General
Interest in the area has been sparked by the discovery by Majescor Resources of large quantities of Aindicator minerals@ which are pathfinders for kimberlites and fragments of kimberlite, the host rock for diamond deposits. Indicator minerals are minerals of specific chemical nature, for example G10 garnets, which are most often found in association with diamondiferous kimberlites.
Also, preliminary exploration by Dianor some 100 km to the northeast of the same structural corridor as the Majescor claims has returned zinciferous chromites (as well as at least one micro diamond) which are said to have similar chemistry to chromites found in diamond bearing lamprophyres in the Wawa area.
Globex and its partners, Aurogin and Sparton, originally staked 616 cells (the equivalent of approximately 1,850 standard un-surveyed claims) on specific targets based on structural parameters and geophysical signatures similar to those that could be found associated with kimberlites. Over 75 claim blocks were acquired each covering one or more individual kimberlite targets. 97 of the cells have been renewed following preliminary field work. The bulk of the renewed claims are in areas 33C09, 33C14, 33D16, 33F03, 33F05 and 33F14.
