Otish Uranium Property
|
| |
|
The Otish Uranium property is located in the western border of the Otish Basin and it consists of 486 contiguous claims totalling 258 km2 including Ditem's Beaver Lake properties. The property is bordered to the south by the Cameco Otish claim block and to the east by the Strateco Matoush property. The Otish Uranium property extends northward to the 52nd parallel and surrounds the UEM claim block on which are reported uranium leached surface assays grading from 0.23% up to 2.46% of U3O8.

Geological Setting
|
| |
|
Regional mapping shows that the property is underlain by the Indicateur Formation of the Otish Group (about 1.7 Ga). The Indicateur Formation consists of conglomeratic arkoses, sandstones with local interlaying of quartz pebble conglomerates and, near the conformity, polymictic conglomerates. As results of Ditem's drilling program illustrate, the Indicateur Formation's sandstones are locally cut by gabbro dykes and important structures with strong hydrothermal alteration. This alteration is usually indicated at the sandstone/gabbro contact. The basement is composed of gneisses with metavolcanics and ultramafic horizons intruded by pegmatites and granites. The total thickness of Otish Group sediments within the property varies and may not exceed 800m.
Uranerz Exploration and Mining Ltd conducted several exploration programs for uranium in the area from 1974 to 1985. The uranium equivalent anomalies recognized by airborne spectrometry survey in the northwest of the property are broader and stronger where the basement is perhaps more exposed. Very strong and wide uranium equivalent anomalies occur in the vicinity and southwest of the Beaver Lake (4 km long) and Pierre (3 km long) uranium prospects.

Milestones and Projected Work
|
| |
|
In early 2007, a 43-101 compliant technical report was completed for the property and a program outlined. Ditem's 2007 exploration program consisted of, among other things, detailed magnetometer, radiometric and TEM airborne surveys at 150 m line spacing . The airborne radiometric survey identified many targets for ground investigation. From this data and already available structure and drill reports from previous work, targeted areas were selected for detailed exploration and drilling. Drilling began in mid-June and seven holes have been drilled to target unconformity deposits. Results of the program have produced weak uranium indications.
In January 2008, Geophysique Camille St-Hilaire undertook a new analysis and interpretation of the 2007 survey incorporating data obtained from the 2007 drill program. As a result of this and other elements the Company undertook a five-hole drill program (totalling 852.8 m) to test targets identified as a result of the 2007 drilling, analysis and interpretation by Geophysique Camille St-Hilaire. One drill hole encountered trace amounts of uranium related to a 10 cm altered gabbro dyke intersection using a RS 125 spectrometer. The core recovered from the four other drill holes completed into the two other conductive anomalies did not show evidence of uranium. These drill holes did encounter significant sulphide mineralization (pyrite and pyrrhotite) that can likely explain the cause of the two anomalies.
Each drill hole was left cased and open for future down hole geophysical surveys to confirm the cause of the three conductors. Selected samples recovered from all the drill holes were submitted to an accredited laboratory for uranium pathfinder, precious metal and base metal chemical analysis.
In early March 2010, a four-hole drilling program was completed in the NE sector of the property. The main goal of this drilling program was to test previous EM anomalies and VLF conductors. Three of the four holes intersected altered gabbro dykes and narrow altered sandstone zones with very low equivalent uranium content using the RS-125 spectrometer.
The Matoush NSR
The Company has a 2% NSR on the Matoush property, which is being explored and developed by Strateco Resources. Strateco has completed an intensive Environmental Impact Study, and the company is moving forward with underground exploration work for the Matoush uranium project feasibility study. In February 2010, Strateco completed a scoping study conducted by Scott, Wilson, Roscoe Associates Inc. with the participation of Melis Engineering Ltd. for processing and SD Energy Associates Ltd. for marketing and price determination. A new drill program, with an estimated total coverage of 120,000 m is planned for 2010 and 2011.
