En route to Aricheng Area
The discovery of the Aricheng C structure marks a break-through in the exploration of the uranium-bearing fault system in the Kurupung Batholith. We knew that uranium occurred within faults that could be identified through geophysics, but with Aricheng C, we now know which parts of the fault system are more likely to contain greater uranium content.
Uranium in the Aricheng Area is contained within structural networks in which east-trending faults link into northeast-striking shear zones. Assay results to date suggest that east-west orientated structures, such as Aricheng C, contain wider intervals of uranium mineralization than northeast-trending ones. Further scout drilling in the Kurupung will focus on east-striking structures identified from the geophysical data.
The Aricheng C structure is orientated east-west and dips about 70° to the north. The structure is marked by a corridor of relatively low magnetism that extends eastward from the area drilled. Mineralization at Aricheng C has been delineated over 150 metres along strike and is open along trend and at depth. Vestiges of uranium mineralization occur in the saprolite at surface and the deepest intercept is approximately 220 metres below surface.
Drill Hole Locations
A total of 1,017 metres in the first four bore holes (Phase I scout drilling) have been completed to date on the Aricheng C structure.
Plan view shows the location of Phase I drill holes at Aricheng C. The collar position of each hole is shown as a dot and the extent of each inclined hole is shown as a black line. U3O8 grade (%) is shown as a histogram along the trace of the bore hole. The coloured background is ground magnetic data (cool colours – green and yellow – mark the least magnetic areas while warm colours – orange and red – mark areas of more intense magnetism).
Long Section
Phase I scout drilling at Aricheng C to date has traced mineralization over a strike length of about 150 metres and remains open along strike. Vestiges of uranium mineralization occur in the saprolite at surface and the deepest intercept is about 220 metres below surface and is open at depth. The Aricheng C structure is orientated east-west and dips about 70º to the north.
A provisional long section of the Aricheng C 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.
