Macusani Yellowcake Inc. (TSX VENTURE:YEL)(FRANKFURT:QG1) has announced that drilling from the ongoing exploration program on Chilcuno zone on the Kihitian uranium property on the Macusani Plateau, Peru, has intersected additional shallow, high-grade uranium values with intersections ranging from 3.0 to 5.0 metres with weighted average grades ranging from 0.081% U3O8 (1.162 lbs/ton) up to 0.260% U3O8 (5.190 lbs/ton).
The latest intercepts are interpreted as possible extensions of the previous drill holes (see September 30, November 26, and December 21, 2010 press releases) and adit channel results (see January 13, 2010 press release).
KIHITIAN – CHICUNO ZONE
The drill program was designed to test for continuity and grade of the uranium mineralization within a shallow, sub-horizontal, 5 to 25 metre thick horizon (A level) of rhyolitic flows and minor pyroclastic sequences hosting "mantos", fracture-filling, vertical joints and disseminated autunite, meta-autunite and weeksite. A similar but generally thicker horizon (B level) occurs approximately 75-100 metres lower stratigraphically, which has been intercepted to date in two boreholes, one with very high-grade U mineralization (see November 26, 2010 press release citing 7m grading 36lbs/t U3O8 as part of a 65m thick continuously mineralized interval).
The shallow "manto" mineralization, which is usually sub-horizontal, was discovered and initially explored through adits by IPEN (Peruvian Nuclear Energy Institute) in early 1980's and it usually dips between horizontal to 10-12 degrees.
The present drilling at Kihitian is part of a 20 platform plan. The four boreholes reported in this press release were drilled on platforms 3, 8 and 9, located south of the adits dug by IPEN in 1980's along a radiometric anomaly that runs on a southwest-northeast trend. The distance covered by these boreholes from the first adits is between 100m, 150m and almost 200m towards south of the main exposed adits.
The Company's CEO, Peter Hooper, stated, "The drilling results at Kihitian continue to demonstrate high-grade intersections which are very encouraging. These results coupled with the previous adit channel and drill results announced late last year indicate the potential for a sizeable mineral resource at Kihitian. The goal of our drilling campaign at Kihitian for 2011 is to demonstrate continuity along strike and at depth and to begin delineating the high-grade mineral resource."
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.
