Macusani Yellowcake Results Continue to Bring in Good News

THE LATEST BEST HOLE DD5-EAST P04 WAS DRILLED TO A DEPTH OF 57.45 METERS. THE AVERAGE GRADE THROUGH THE TOTAL HOLE WAS 1.290 LBS/TON U3O8 WITH THE BEST INTERVALS BEING: - 5.090 LBS/TON OVER 10.20 METERS - 1.668 LBS/TON OVER 10.21 METERS

TORONTO, ONTARIO--(Marketwire - March 11, 2008) - Peter Hooper, President of Macusani (TSX VENTURE:YEL) stated: "The drilling now demonstrates mineralization over a strike length of 600m. Current drilling has one drill stepping out 250m to the West and a second drill stepping 200m to the North."

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 4 ("P04") and Platform 5 ("P05").

As with the previous intercepts (see previous press releases dated November 12, 2007, December 14, 2007, February 18, 2008 and February 25, 2008) each hole intersected multiple horizontally-oriented uraniferous zones at depths starting at surface down to 62.00m. The uranium minerals are hosted in acidic volcanic rocks of rhyollite composition that cover large portions of the Macusani Plateau in "blanket like" formations from surface to a depth of approximately 100m.

The assay results from the latest three holes are shown in the table below (Note: The interval lengths are measured along the core length and may not represent true widths.):

These encouraging new set of drill results continue to indicate the presence of strong near-surface uranium mineralization. The valuation of this close-to-surface mineralization will be an ongoing project during the year.

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, disseminated, non-mineralised) b u t usually not more than 1m per sample. A t SGS in Lima the core samples are crushed, pulverised, homogenised and a 250g riffled representative sample analysed 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.

Mr. Ian Foreman P.Geo., of Foremost Geological Consulting, is the Qualified Person, as defined under National Instrument 43-101, for the Colibri Property and has reviewed the technical information used in the preparation for this release.
