Macusani Yellowcake Reports Further Results from Drilling at the Flagship Kihitian Uranium Property

08:19 EDT Tuesday, May 28, 2013

TORONTO, ONTARIO--(Marketwired - May 28, 2013) - Macusani Yellowcake Inc. (the "Company") (TSX VENTURE:YEL)(FRANKFURT:QG1) is pleased to announce assay results from an additional five drill holes from the ongoing drilling program at the Chilcuno Chico anomaly on the Kihitian Property in Puno, southeastern Peru. These results continue to extend both the Manto "A" mineralized zone and deeper Manto "B" zone. The best result was from drill hole PT-CH23-TSE, with a 13m intersection along Manto "B" from 247m to 260m, that returned a weighted average of 1,962ppm U3O8 (or 3.852 lbs/ton) including two higher-grade zones: the top zone of 3m that averaged 800ppm U3O8 (or 1.600 lbs/ton) and the bottom zone of 5m that averaged 4.491ppm (or 8.982 lbs/t) - see below for all results.

"Our latest drill results continue to extend Manto "B" as a continuous mineralized sequence occurring under the entire Chilcuno Chico area. We believe that excellent open pit mining potential exists on the periphery of the area where the manto is thicker. The core would be an underground target with a very steady orientation, inclination, thickness and grade, which may be suitable for mechanized underground techniques." said Dr. Laurence Stefan, President and CEO. "The drill results and related geological model continue to suggest that Manto "B" is a continuous mineralized layer that extends onto the neighbouring properties that the Company acquired as a result of the merger with Southern Andes Energy in 2012."

Selected assay results from boreholes drilled at Chilcuno Chico include:

These results are from holes drilled towards the south and southwest from the existing geological resource within the Chilcuno Chico target on the Kihitian concession. To date, drilling within the Chilcuno Chico anomaly has delineated an area of approximately 920 m by 900 m where Manto "B" remains open in all directions. Although Manto "A" shows continuity there is less consistency with respect to its shape and the occurrence of uranium mineralization compared to Manto "B".

Current Exploration

At present, the Company is operating six diamond drill rigs on the Macusani plateau: three drills on the Kihitian project (one drill at Quebrada Blanca and two drills at Chilcuno Chico) and three drills at the Tupuramani anomaly that represents the westward extension of the existing geological resource calculated at Colibri 2 and 3.

This phase of intense drilling will end within the next 45 days. A resource estimation has already been started by Mineral Corporation in Johannesburg, South Africa and will be released when completed. Concurrently, a Preliminary Economic Assessment started by GBM in London, UK is continuing and will be completed once the new geological resources at Chilcuno Chico, Quebrada Blanca and Tupuramani are estimated.

Previous assay data, maps and a sample cross section are available on the Company's website at www.macyel.com/properties/.

Quality Control and Analytical Procedures

Core samples have been crushed and representative samples analyzed for Uranium (U) abundance and a suite of 40 elements. The necessary analytical quality control and assurance has been completed by insertion of reference material, duplicate samples and blank material. After crushing, the core is placed in sealed bags and shipped to the CIMM's preparation laboratories in Juliaca, Peru. Following the preparation stage, the sample pulps are sent to CIMM analytical laboratory in Lima where U and a suite of forty other elements are analysed using ICP-MS methodology.

CIMM Peru is an ISO certified assay laboratory. The program is designed to include a comprehensive assay quality control routine comprising the systematic use of standards, blanks and field duplicate samples. Secondary laboratories are used for check assaying.
