Macusani Yellowcake Inc. (the "Company") (TSX VENTURE:YEL)(FRANKFURT:QG1) is
pleased to announce the first recovery results from tests conducted on higher
grade uranium mineralization from the Kihitian property on the Macusani plateau.
The samples were collected from the Pinocho and Chilcuno Chico targets within
the Kihitian property. Very high levels of uranium extraction of over 99% were
achieved, see Table I. These are the first recovery results from the Kihitian
property and are consistent with the excellent amenability to leaching reported
for samples from nearby Colibri 2/3 property.

In addition to the high recoveries, the test results also showed fast leaching
kinetics. Figure I illustrates the fast kinetics of a higher grade bottle roll
test and shows that the leach reaction is almost complete in less than two
hours. 


Acid consumption ranged from 302 to 380 kg/t. Although this level of acid
consumption appears high, these samples contain more uranium to dissolve than
lower grade samples. Acid consumption on a "per gram of uranium" basis is
actually lower. 


A very important trend was observed when comparing the assayed head grades and
the calculated head grades. The assayed head grades of samples were 2.94, 4.14
and 13.39 %U, as assayed by Certimin Laboratories in the initial exploration
assays. In contrast, the calculated head grades (3.57, 9.00 and 15.85 %U) are
significantly higher. The calculated grades are 18% to 121% higher than the
assayed grades. Calculated grades are more accurate than assayed grades since
leach solution concentration is homogeneous and easy to sample and potential
fire assays errors are confined to the diminished values in the leach residue.
This finding could have major implications for the size of the mineral resource.

President and CEO, Dr. Laurence Stefan, stated: "The fact that the most recent
bottle roll tests of higher-grade samples collected from Pinocho and Chilcuno
Chico have yielded in some cases more than double the reported uranium assays,
is a nice problem to have. We are also impressed by the very high recoveries of
these higher-grade uranium samples, all in excess of 99%. These recovery results
increase our confidence that uranium may be profitably mined from the Macusani
plateau in the future." 


The leaching tests and associated analyses have been run under the same standard
conditions by TECMMINE EIRL, a Peruvian metallurgical consulting firm contracted
by Global Gold SAC, the subsidiary in Peru of Macusani Yellowcake Inc., for
in-house uranium metallurgical and processing investigations. 


Macusani wishes to stress and caution that these high recoveries in bottle roll
leaching tests are from a very limited number of samples and may not be
replicated in future testing.
