The assessment and exploitation of deeper, more structurally-complex orebodies requires significantly greater input from Structural-Economic Geologists experienced in the applicable style of deformation and mode of mineralization. The great majority of Competent Person’s Reports, Technical Reports and Feasibility Studies contain little or no input in terms of a structural analysis or structurally-coherent orebody domaining. This, in turn, results in modelled orebodies, which form the basis of Mineral Resource Estimates, Mineral Reserve Estimates and related Feasibility Reports, that are both unrealistic and unconstrained by sufficient 2D and 3D data. This usually manifests as an over-estimation of contained metal, over-simplifications or spatial and geometrical unrealism
An understanding of the structures, host rocks and alteration zones, which either control or surround an orebody, is also lacking from the great majority of reports on which investment decisions are based. These parameters, which may adversely affect the viability of a prospect or deposit, are almost invariably overlooked, particularly in complex structural settings. This deficit, in the understanding of the volume of interest, propagates into subsequent Pre-Feasibility and Feasibility Studies
Time and care are taken to fully elucidate all relevant parameters
TECT’s approach is to place significantly more emphasis on the early and up-front resolution of as many of these parameters as data allows, so that all subsequent reports and investment decisions are fully-informed. Our Technical and Competent Person’s reports, compiled in collaboration with our Partners and Associated Mineral Resource experts, are distinguished by the time and care taken to fully reflect and report all relevant parameters.
TECT has reviewed published reports for an array of clients, from large institutions to high net-worth individuals, across a variety of mineralization styles. These reviews may be undertaken pro-actively, prior to an investment, or retrospectively after an investment has been made. The objective of these audits is to describe, in an understandable and coherent manner, the workflows, supporting data and methodologies used to inform resultant Mineral Resource/Reserve Estimates and their associated decisions. Our work describes how these data sets, and the 3D models that result from them, are incorporated into companies published reports, along with relevant caveats and pitfalls.
