Aricheng A is the eighth uranium-bearing structure identified and underscores the growing size potential of the Kurupung system, a promising uranium district in South America. Uranium mineralization at Aricheng A is associated with a set of northeast-trending structures, marked by a conspicuous radiometric anomaly. Aricheng A is located about 500 metres southeast of the Aricheng North uranium zone that coincides with another strong radiometric feature. The Aricheng A mineralization zone occurs in veinlets and micro-breccias within an envelope of albite-chlorite-hematite-calcite-magnetite alteration that is weakly to moderately magnetic. The structures have a northeast strike and dip approximately 80º to the northwest. Mineralization has been encountered over a strike length of 300 metres, to a depth of 120 metres, and remains open at depth.
Drill Hole Locations
A total of 1,243 metres in the first seven bore holes (Phase I scout drilling) have been completed to date on the Aricheng A structure.
Plan view shows the location of Phase I drill holes at Aricheng A. The collar position of each hole is shown as a yellow dot. The coloured background is radiometric data from a field survey (warm colours indicate areas with higher radioactivity). Aricheng A is located on a conspicuous radiometric anomaly, which is situated southeast of the uranium zone previously drilled at Aricheng North, marked by another strong radiometric feature.
Long Section
Phase I scout drilling at Aricheng A to date has traced mineralization over a strike length of about 300 metres, to a depth of 120 metres, and remains open at depth. Uranium mineralization at Aricheng A is associated with a set of northeast-trending structures, marked by a conspicuous radiometric anomaly. The structures have a northeast strike and dip approximately 80º to the northwest.
A provisional long section of the Aricheng A structure shows the distribution of grade-thickness values (the product of the width of the mineralized interval and its U3O8 grade in %) on a vertical projection of the structure. A pierce point is the approximate location at which each bore hole intersects the mineralization.
