The host of the mineralization is the same young age Macusani rhyolite rock that displays disseminated and fissure-controlled uranium minerals. The main mineral species are meta-autunite and autunite that have demonstrated to provide high metallurgical recoveries, between 91 to 97% (see the Company's press release dated August 9, 2012).
Previous assay data, maps and a sample cross section are available on the Company's website at www.macyel.com/kihitian/.
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 CERTIMIN's preparation laboratories in Juliaca, Peru. Following the preparation stage, the sample pulps are sent to CERTIMIN analytical laboratory in Lima where U and a suite of forty other elements are analysed using ICP-MS methodology.
CERTIMIN 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.
Update on Current Exploration
Drilling continues at the Quebrada Blanca anomaly, with one rig extending the drilling activities towards south and east of the main ravine. The purpose is to test at depth visual uranium mineralization that outcrops on surface.
At present, the Company is operating five 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 two drills that work at the new Tupuramani anomaly in order to test the western extension of Colibri 2 and 3. Results from the drilling at Tupuramani appear to be very similar in grade and volume with the mineralization modeled at Colibri 2 and 3 and will be released during February 2013.
