DNI REPORTS ADDITIONAL BIOLEACHING RESULTS, INCLUDING SPECIALTY METALS AND RARE EARTH ELEMENTS FROM ITS BLACK SHALE PROJECTS, ALBERTA
DNI Metals Inc.

(DNI:TSX-Ven)(DG7:FSE) is pleased to announce consolidated results from a series of bioleaching R&D studies which conclude DNIs initial testwork on surface samples from its Alberta polymetallic black shale projects, Athabasca Region, Alberta.
The bioleaching studies were carried out by Alberta Innovates Technology Futures (AITF, formerly the Alberta Research Council) to specifications formulated by DNI and Dr.Corale Brierley, of C.L.Brierley Consultancy LLC, Denver, who has been assisting DNI during the past two years as its bioleaching consultant, in formulation of DNIs bioleaching testwork programs.
The studies were implemented in several iterative stages commencing in late 2009, and were completed at the end of 2010.

The studies collectively confirmed that suitable bioleaching organisms are indigenous to the shale and can be readily extracted, cultivated and adapted to the shales chemistry.

The studies also confirmed that a broad suite of metals can be collectively extracted from the shale, with high recoveries for Ni/U/Zn/Co/Cd and lower recoveries for Mo/V/Cu/Li which might be enhanced through optimized leaching parameters.

Results from the above studies are consistent with results from concurrent bioleaching testwork previously announced by DNI carried out by the Bureau de Recherches G�ologiques et Mini�res (BRGM), France, (press Apr28/2010), and simple sulfuric acid leaching tests conducted under DNIs direction at Canadian analytical facilities (press Mar4/2010).
Two sets of surface samples (#BK003 and #BK456) were tested, both of which were collected by DNI during its 2009 surface trench sampling from a 9.5m thick mineralized exposure of Second White Speckled Shale at the Buckton South Zone located approximately 9km to the south of the Buckton Mineralized Zone.

Sample BK003 represents material collected over 2m of true width, and sample BK456 is a composite sample collected over approximately 4m of true width beneath sample BK003.

The Buckton South Zone either represents the southerly projected extension of the Buckton Mineralized Zone, or is a separate similar mineralized Zone which has not yet been drilled (cored) by DNI, although 12m-23m thicknesses of the Speckled Shale Formation are reported in downhole logs from approximately twenty historic oil/gas wells throughout a 100-150 square kilometer area.
