Kingsland has started reinterpretation of geology and geological controls of uranium mineralisation at its Cleo project after the recently completed drill program confirmed historical drill intercepts.
The 30-hole program consisting of 3,228m of reverse circulation and 450m of diamond core drilling returned results such as 16m grading 1,435 parts per million (ppm) U3O8 from a down-hole depth of 116m including 0.4m at 29,197ppm (2.9%) U3O8 at CLRCD023 and 47m at 924ppm U3O8 from 53m at CLRC017.
Kingsland Minerals (ASX:KNG) noted that the drilling provided additional information and data for a more detailed geological interpretation and extended known mineralisation along strike and at depth.
Reinterpretation of the geology and geological controls of uranium mineralisation is a precursor to planning additional drilling next year that will enable a Resource estimate later in 2023.
Drill results
Diamond drilling completed by the company shows that the higher grade uranium intersections are generally controlled by the position and possibly orientation of granitic intrusions.
The contact between the sedimentary Masson Formation and the Cullen Granite batholith provides an eastern contact constraining uranium mineralisation.
At Cleo, the Masson generally consists of a series of graphitic, schistose sediments which are intruded by a series of later felsic/granitic dykes varying in downhole width from centimetres to several metres.
Higher grade mineralisation is generally found in the sediments where it can be seen to mimic the intrusive/sediment contact but is also contained within the intrusive in places.
Kingsland noted that there may be different phases of intrusions into the sediments and one or more of these phases may be associated with uranium mineralisation.
Additionally, fault zones were intersected in the diamond drilling with a southwest dip interpreted.
These faults may have dislocated geological contacts and/or mineralisation while a target also exists for future exploration on the southeastern or hanging-wall contact.
Future drilling will focus on areas with little or no previous drilling that represent excellent potential for extensions of the uranium mineralisation.
