Macusani Yellowcake Inc. (the "Company") (TSX VENTURE:YEL)(FRANKFURT:QG1) is
pleased to announce preliminary results from tests conducted using four large
leaching columns that have been installed at Isivilla on the Macusani plateau
and loaded with uranium-mineralized material obtained from metallurgical core
drilled on the Colibri 2 & 3 tenement. High levels of uranium extraction were
achieved, 91 to 98 %, resulting in low residual uranium content. Very low
sulfuric acid consumption was observed, 9.6 to 10.5 kg/t. The test results are
summarized below in Table 1.

President and CEO, Dr. Laurence Stefan, stated: "The recent column leaching
tests have returned high recovery rates with very low acid consumption and
continue to demonstrate the very favourable metallurgical characteristics of the
Macusani uranium mineralization. The results also hint towards low production
costs. The excellent uranium extraction results obtained during these tests,
which were run under simulated "mine conditions" and combined with the extremely
low acid consumption, further support a technical and economic case for a low
grade uranium heap leach operation on the Macusani plateau." 


The Company believes that these results are very encouraging and informative for
the further development of the project. Further column leach tests are planned
followed by the progression to full height large-scale column and pilot plant
tests. 


Although the recent tests have been run at high altitude, 4500masl using local
water and at local Andean climatic conditions in Macusani, the final recoveries
were consistently better than most of the previous column leaching tests run in
Lima under laboratory conditions. The main reason for this positive correlation
may be due to the optimized conditions under which the tests were conducted as a
result of the processing experience gathered during the previous tests. 


Figure 1 below illustrates the progressive transition from early stage
metallurgical testing towards pilot scale operation and the rapid progress made
to date by the Company in understanding the metallurgical process and modelling
of a probable flow-sheet for a future mine and uranium plant suitable for the
treatment of Macusani uranium mineralization.

Test Methodology and Conditions

Four column tests were completed successfully on site, using site water and at
site conditions (altitude, temperature, humidity). Approximately 460 kg of
crushed sample was loaded into 16.5 inch diameter columns to a height of
approximately 3.0 m. Crushed sample sizes of 100 % passing 1 inch and 2 inches
were utilized. The columns were drip irrigated at 8 (l/h)/m2 achieving a
percolation velocity of around 1 m/d. An acid concentration of 15 g/l was
maintained and a pH less than 2. The duration of each test ranged from 45 to 50
days. 


Figure 2 below shows representative leach extraction kinetics and acid
consumption curves. The results indicate that the extraction and acid
consumption are relatively consistent across the range of grade and feed size
tested in the large format column with 90 % of the uranium extracted after 30
days of irrigation.

The breakdown of the uranium-mineralized rhyolites can be summarized as follows: 



(i)   day 3: column breakthrough                                            
(ii)  day 18: 80% recovery                                                  
(iii) day 30: 90% recovery                                                  
(iv)  day 50: commencement of column wash.                                  



The leaching tests and associated analyses have been run by TECMMINE EIRL, under
the supervision of Jose Mallqui Romayna, 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.
