TORONTO, ONTARIO--(Marketwire - Oct. 1, 2012) - Denison Mines Corp. (TSX:DML)(NYSE MKT:DNN)(NYSE Amex:DNN) ("Denison" or the "Company") is pleased to announce that the Phase 1 drilling program on its 100% owned Mutanga uranium project in Zambia has identified additional mineralization along the Dibwe-Mutanga corridor and deeper mineralization beneath the Dibwe deposit. The Phase 2 program is currently underway and is anticipated to be completed in November.
Some of the better mineralized intersections from Phase 1 are listed in Table 1 below and their locations are shown on the attached map. A complete table of results from all Phase 1 drill holes, titled "Mutanga Project 2012 Phase 1 Drill Results" can be found on Denison's website at www.denisonmines.com.
|Table 1: Highlights of Phase 1 Drill Program|
Phase 1 Drill Program
A total of 12,352 metres has been completed in 91 core and reverse circulation drill holes since May 2012. There were three primary objectives for the program: (1) locate additional mineralization along the Dibwe-Mutanga corridor that includes the Dibwe East deposit discovered in 2011; (2) locate deeper, stacked mineralization beneath the Dibwe and Mutanga deposits; and, (3) test other exploration target areas, particularly Dibwe North.
Of the 91 holes drilled to date, a total of 31 have been completed along the Dibwe-Mutanga corridor. These are wide spaced holes 200 to 400 metres apart which were designed to locate additional mineralization on this underexplored trend along strike to the northeast and southwest of the Dibwe East deposit. The best result was in drill hole DMC 1220, which intersected 25.5 metres at 327 ppm eU3O8, from 9.7 metres to 35.2 metres below surface. This drilling has been successful with 10 holes returning 12 intersections with a grade x thickness (GT) greater than 500 ppm eU3O8*m. The average GT of these 12 intersections is 1,864 ppm eU3O8*m.
Wide spaced (400 metres) drilling designed to intersect deeper, stacked mineralization beneath the Dibwe and Mutanga deposits has returned significant intersections at each deposit. Fourteen holes were completed at Dibwe, and four at Mutanga. At Dibwe, drill hole DBC1229 intersected 99.3 metres averaging 327 ppm eU3O8 from 18.0 metres to 117.3 metres, a GT of 32,453 ppm eU3O8*m, which extended mineralization to previously undrilled depths. At Mutanga, three intersections with a GT greater than 100 ppm eU3O8*m were intersected below previously drilled mineralization in drill hole MTD1209.
Results of drilling at other exploration target areas were mixed. Five holes of 42 drilled returned GT values greater than 500 ppm eU3O8*m. Numerous narrow (<1 metre) and low grade (<200 ppm) intersections were obtained at Dibwe North, but future drilling will focus on other areas that have a greater potential for thicker and higher grade intersections.
The grades reported are equivalent U3O8 grades based on down-hole radiometric probing at a cut-off grade of 100 ppm eU3O8; geochemical assay results have not been received at this time. All intersections and geological interpretations are based on diamond drill core or reverse circulation drill chips only and mineralized intervals may not represent true thickness. However, the drill holes were drilled steeply at -75 degrees to -90 degrees into mineralization that generally dips shallowly at 0 to 20 degrees, so the true thickness is expected to be within 90% of the intersection length.
Phase 2 Drill Program
Phase 2 drilling has begun to follow up on the most prospective results from Phase 1. Approximately 9,000 metres in 70 drill holes are planned. This drilling should be completed in November. Concurrently, surficial geochemistry and radon orientation surveys are being implemented to test these techniques over known mineralization at the Dibwe East, Dibwe and Mutanga deposits. If successful, the techniques will be applied to other higher priority portions of the Mutanga Project to generate additional drill targets on the property.
