Location and Access
The Santa Barbara Property covers an area of over 44,700 hectares. The property represents the northernmost uranium-mineralized area identified along a NW-SE trend of airborne radiometric anomalies that continues into the Anit and Ivana properties to the south, in central Rio Negro Province. The property has year-round access through a well-maintained gravel road, and is in a semi-arid area with low rainfall and population density.
The Santa Barbara property was the initial uranium discovery made by Blue Sky in 2007 and provided the impetus for the Company to undertake the initial airborne radiometric survey. Uranium mineralization at Santa Barbara is directly related to three parallel airborne radiometric anomalies measuring 11 kilometres, 6.5 kilometres and 5 kilometres in length and up to 1.5 kilometres in width. Pitting in the anomalous zones located uranium mineralization at depths up to two metres. Additional field work included the 2010 detailed airborne survey, radon gas and spectrometer surveys, pit sampling, and auger and rock sampling. Several zones of flat-lying near-surface mineralization were delineated with yellow carnotite-bearing mineralization. Significant results range from 0.1 to 0.24% U3O8.
The first reverse circulation (“RC”) drilling program was completed in 2017. It was considered a scouting program only, and testing an area of approximately 450 hectares. Fifteen holes were drilled ranging from 4 to 25 metres depth, for a total of 312 metres. Values of uranium and vanadium were low in all holes.
The main uranium mineralization recognized to date is related to NE-SW structural lineaments within Late Cretaceous sediments, with minor mineralization related to scarce outcrops of the Middle Tertiary unit, the Chinchinales formation. Carnotite coats grains in sand and gravel.
