Introduction
The Lazy Edward Bay property is located along the southern margin of the Athabasca Basin, approximately 75 kilometres west-northwest of the Key Lake uranium mine. The property also covers the southern shore of Cree Lake and consists of 12 mineral claims, comprising 48,310 hectares.
Denison Mines Corp. (Dension; formerly International Uranium Corporation) has earned a 75% interest in the project. The property is subject to an underlying 2.5% net smelter return royalty (NSR) held by Kennecott Canada, reducible to 1.25% by payment of C$1,000,000 to Kennecott. JNR is the project manager.
Previous Work
The Lazy Edward Bay property was first explored in 1969 and on a sporadic basis until 1989. The operators at that time recognized the merits of further work, but pulled out due to budget restraints and their current focus on the eastern Athabasca Basin. Past programs included an assortment of prospecting, geophysical and geochemical surveys, as well as diamond drilling. Several major conductive trends were outlined, some of which are untested and others poorly tested. A number of broadly spaced drill holes that reported encouraging geology and/or geochemical results were never followed up, and a uraniferous boulder anomaly, the source of which is interpreted by previous workers to exist on the property, remains unexplained. This is of particular interest in that the Key Lake deposits were discovered by following up boulder anomalies.
No further work was undertaken until JNR and its partner at the time, Kennecott Canada, acquired the property in 1999. A 1000-line kilometre airborne GEOTEM survey was flown over the property in November 2000. In 2001, an exploration program consisting of grid establishment, ground geophysical surveys and diamond drilling focused on a number of prospective targets identified from historic work and the GEOTEM survey.
A total of 8 holes were drilled during the 2001 winter program. The best geochemical results were obtained over a 2-km strike length of the Horse Conductor, where positive geological features had been noted in six holes (LE-01, -03, -04, -06, -07 & -8). Previous operators had identified elevated radioactivity and prospective geochemistry in this area. Elevated to anomalous levels of pathfinder elements such as nickel, lead, copper, vanadium, cobalt and boron occur in the basement rocks of these holes.
Of special note are highly anomalous zinc values (up to 0.62%) in drill hole LE-01. The clay geochemistry along the Horse Conductor is typically mixed kaolinite/illite, a signature commonly associated with uranium mineralization in the Key Lake area. These geological and geochemical features are considered favourable for the development of uranium mineralization along the Horse Conductor.
Current Program
A planned 3,000-metre diamond drilling program along with approximately 75 kilometres of linecutting and a ground electromagnetic (EM) survey has been completed on the Lazy Edward Bay project. The drill program tested interpreted bedrock conductors defined by ground EM surveys completed in the summer of 2006 and winter/spring of 2007. Results are pending.
Drill targets included: 1) Three relatively untested, long strike-length EM conductors identified in the summer of 2006 and coincident with drill-confirmed structural disruption of the unconformity; and, 2) Five separate complex bedrock conductive systems defined by the 2007 ground EM surveys.
The 2008 linecutting and geophysical program will focus on the westernmost claims within the Lazy Edward Bay project and ground define future structural/conductive drill targets interpreted from a 1,800 line-kilometre airborne EM and magnetic survey flown during the fall of 2006.
Quality Assurance / Quality Control
