Macusani Yellowcake is Pleased to Announce Its Best Hole to Date. Diamond Drill Hole DD 3 South P04 was Drilled to a Depth of 62.3 Metres of Which 52 Metres was Mineralized
THE AVERAGE GRADE OF THE FIRST 38.7 METRES WAS 1.9 POUNDS PER TON U3O8. THE BEST INTERVAL WAS 11.08 METRES RUNNING AT 6.5 POUNDS PER TON U3O8.TORONTO, ONTARIO--(Marketwire - Feb. 26, 2008) - Macusani Yellowcake Inc. (TSX VENTURE:YEL) -
Peter Hooper, President of Macusani stated: "These results continue to confirm our model of a very large horizontal bedded structure containing substantial amounts of uranium. These wide higher grade sections, 11.08 meters of 6.5 pounds per ton U3O8, give confidence that the continuity will prevail".
Macusani Yellowcake Inc. ("Macusani")(TSX VENTURE:YEL) is pleased to announce assay results from the ongoing drilling program at its Colibri II uranium property on the Macusani Plateau in southeastern Peru. These holes were drilled from the two drill collars which have been designated as Platform 3 ("P03") and Platform 4 ("P04").
As with the previous intercepts (see previous press releases dated November 12, 2007, December 14, 2007 and February 18, 2008) each hole intersected multiple horizontally-oriented uraniferous zones at depths starting at surface down to 62.00 m. The uranium minerals are hosted in acidic volcanic rocks of rhyolite composition that cover large portions of the Macusani Plateau in "blanket like" formations from surface to a depth of approximately 100 m.
The assay results from our next four holes are shown in the table below (Note: The interval lengths are measured along the core length and may not represent true widths.):

Quality Control
The Company employs a QA/QC protocol on all aspects of its analytical procedures. Whole core samples are sent to SGS Laboratories Peru in Lima, Peru. Samples are taken in intervals depending on the geological boundaries and type of mineralization (veins, veinlets, stockwork, dissemination, non-mineralized) but usually not more than 1m sample. At SGS in Lima the core samples are crushed, pulverized, homogenized and a 250g riffled representative sample analyzed for Uranium using ICP-MS techniques on a suite of 50 chemical elements.
Two blank sample and two standards covering a range of grades are inserted every 50th sample. The pulps are stored at present at SGS in Lima.
