Magnetic modelling and geological modelling come together at the Kintyre uranium deposit

Abstract

We present a case study whereby unconstrained magnetic modelling accurately defined the altered host lithology of the Kintyre Uranium deposits, verified by detailed geological modelling. The Kintyre Uranium deposits are hosted by a sequence of iron and carbonate rich meta-pelites, which makes it an ideal target for magnetic prospecting. As part of the resource definition, magnetic modelling and geological modelling were performed over the Kintyre deposit independently. In the process of further refinement of the magnetic model through incorporation of geological constraints it was determined the two models were already highly complementary and further modelling was not warranted, particularly at the resolution of the magnetic data. This case study demonstrates that in some geological environments, unconstrained geophysical models can adequately map stratigraphy & structure for drillhole target generation.
