Duke Exploration Limited announced the results of new geophysical data processing and drill target ranking at the Bundarra project in Central Queensland, consistent with Duke's previously outlined pluton-wide expanded and accelerated exploration strategy. Very encouraging preliminary observations from new diamond drilling at Quorn and Isens prospects are also reported. Future work planned at Bundarra includes: Further detailed ground checking and geological mapping in vicinity of priority targets; Diamond drill testing of best conductivity anomalies; Further diamond drilling in Quorn area. Duke Exploration has interpreted historic Versatile Time-Domain Electromagnetics (VTEM) data that was acquired over the Bundarra area in 2011 by previous owners of the project. VTEM data was reprocessed by TechnoImaging LLC of Utah, USA, who are experts in providing 3D imaging solutions of a variety of geophysical data, including airborne electromagnetics. TechnoImaging utilised their proprietary EMVision® software and GlassEarth® technology to produce a 3D model of conductivity and chargeability to a depth of 300 m below surface covering most of the Bundarra project area. When combined with Duke's soil sampling data, the 3D geophysical model highlights numerous coincidental conductivity and copper in soil anomalies around the Bundarra pluton's 50 km long contact. The announcement on 15 September 2021 outlined Duke's profile targeting system that utilised conductivity derived from processed Gradient Array IP (GAIP) data and pXRF copper in soil results to define the location and likely size of mineralisation targets around the Bundarra pluton. Processing the historic VTEM data and extending soil surveys has allowed the technique to be further modified and applied over an expanded area where there was no GAIP coverage. The new processing allows both the horizontal and vertical extent of conductors to be defined by manually examining successive depth slices (at 100 m, 170 m and 240 m) through the 3D conductivity model. A set of linear trends were digitised on each depth slice to define conductive zones, which were then correlated with surface copper in soil anomalies. A total of 39 km of linear conductive trends were identified through this targeting analysis from which 19 km were associated with anomalous copper in soil. The majority of conductive trends associated with copper in soil anomalies are untested by drilling. The large scale of the combined geophysical and geochemical anomalism provides excellent exploration potential. The interpreted VTEM conductivity inversion model data was added to Duke's spatial prospectivity database that includes data from soil samples, drilling results, historic workings, defined resource and exploration target size. Prospect areas are defined by polygons, which are weighted according to the strength of the various inputs, e.g. higher copper in soil assays contribute to a higher rank for a prospect. Rankings are relative and allow Duke geologists to assign priorities for drill testing. Geological mapping and assessment of the ranked targets has begun to help guide RC drill-testing planned for early 2022.
