Macusani Yellowcake said that drilling from the ongoing exploration program at the Chilcuno zone in the Kihitian uranium property on the Macusani Plateau, Peru, has intersected additional shallow, high-grade uranium values.
The intersections range from 3.0m to 5.0m with weighted average grades ranging from 0.081% U3O8 (1.162lbs/ton) up to 0.260% U3O8 (5.190lbs/ton).
The drilling program was designed to test for continuity and grade of the uranium mineralization within a shallow, sub-horizontal, 5m to 25m 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 75m-100m lower stratigraphically, which has been intercepted to date in two boreholes, one with very high-grade U mineralization..
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 company said that the present drilling at Kihitian is part of a 20 platform plan.
