Macusani Yellowcake Intersects 11 m Grading 0.20% U3O8 (4.0 lbs/ton) at Kihitian Property, Peru

TORONTO, ONTARIO--(Marketwire - Aug. 10, 2011) - Macusani Yellowcake Inc. (the "Company") (TSX VENTURE:YEL) (FRANKFURT:QG1) is pleased to announce additional assay results from the drilling program on two platforms, PT-CH17 and PT-CH2, at the Chilcuno Chico area on the Kihitian Property on the Macusani Plateau in Puno, Peru. The exploration program, which targeted the deeper Manto "B" zone, intersected 11 m with a weighted average grade of 2,042 ppm U3O8 (or 4.084 lbs/ton) from 85 to 96m. This intersection represents the high-grade portion of a larger 27 m intersection (from 74 to 101m) with a weighted average grade of 862 ppm U3O8 (or 1.724 lbs/ton).

President and CEO, Peter Hooper, stated: "We are very pleased that the drilling campaign at Kihitian continues to trace the deeper Manto "B" zone with high grades. Our exploration to date has demonstrated consistent, high grading uranium values over good widths and we remain optimistic that the Manto "B" zone could develop into an economic underground deposit."

Assay results are shown in following table:

PT-CH17-TNW		From		To		Intersection		Grade		Grade
121.50m depth						(m)		(ppm U3O8)		(lbs/ton U3O8)
		74.00		101.00		27.00		862		1.724
including		85.00		96.00		11.00		2,042		4.084
PT-CH2-TSE		From		To		Intersection		Grade		Grade
103.50m depth						(m)		(ppm U3O8)		(lbs/ton U3O8)
		50.00		55.00		5.00		699		1.398
*Note – intersections do not represent true widths.

Platform 17 is located 120m to the northwest of the adits which were excavated by IPEN during the 1980's, while Platform 2 is situated 200m to the north of the same adits, as illustrated on Figure 1 (http://www.macyel.com/pr10aug2011/). Platforms CH17-TNW and CH2-TSE are 210m apart and located next to the access road built by the Company to the drilling area, on a lower elevation zone where Manto "A" was completely eroded and Manto "B" is closer to surface.

In borehole CH17-SW the Manto "B" zone intersected between 74.00 to 101.00m for 27 metres with a weighted average grade of 0.0862% U3O8 (1.724 lbs/ton), including 11m of 0.2042% U3O8 (4.084 lbs/ton) at a depth between 85.00 to 96.00m from surface.

Borehole CH2-TSE intersected the mineralized Manto "B" zone between 50.00 and 55.00m for 5 metres with a weighted average grade of 0.0699% U3O8 (1.398 lbs/ton).

Borehole CH2-TSE was drilled inclined at 55 degrees towards SE while borehole CH17-TNW was drilled inclined at 55 degrees towards NW. The mineralized intersections may not represent true widths.

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.
