Macusani Yellowcake Intersects 15 m Averaging 0.058% U3O8 (1.2 lbs/ton) Including 2 m Grading 0.384% U3O8 (7.7 lbs/ton) at Kihitian Property, Peru

TORONTO, ONTARIO--(Marketwire - Sept. 29, 2011) - Macusani Yellowcake Inc. (the "Company") (TSX VENTURE:YEL)(FRANKFURT:QG1) is pleased to announce additional assay results from the drilling program at the Chilcuno Chico anomaly on the Kihitian Property in Puno, Peru. The exploration program, which targeted the deeper Manto "B" zone, intersected 15m with a weighted average grade of 583 ppm U3O8 (or 1.166 lbs/ton) from 237 to 252m including a 2m high-grade intersection (from 248 to 250m) with a weighted average grade of 3,842 ppm U3O8 (or 7.684 lbs/ton).

President and CEO, Peter Hooper, stated: "In addition to demonstrating continuity along strike and at depth for both mineralized zones, drilling thus far has resulted in an increased strike length of 400 metres on the A zone and 700 metres on the deeper B zone. Based on the assay results to date, we remain optimistic that the Kihitian property will help to define the Macusani Plateau as a significant uranium district."

Assay results are shown in following table:

Previous assay data, maps and a sample cross section illustrating the A and B mineralized zones are available on the Company's website at www.macyel.com/kihitian/.

The Company is currently operating three drill rigs on the Kihitian property including a recently mobilized rig on the Quebrada Blanca anomaly 2 km NW of Chilcuno Chico. The Company expects to release additional assay results in the coming weeks and remains on target to publish an initial NI 43-101 resource estimate for Kihitian before the end of the year.

Quality Control and Analytical Procedures

Core samples have been crushed and representative samples analysed 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. 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.
