TELEMARK Geosciences AT THE AIG/AAG SEMINAR IN PERTH on the use of applied mineralogy in exploration
Dennis will presented two talks at the joint AIG/AAG exploration seminar on the use of applied mineralogy in exploration held in Perth, Western Australia on April 9, 2019.
The first presentation was an "Introduction to Integrating Geochemical and Mineralogical Data in Hydrothermal Systems" which reviews examples on the use of applied mineralogy in exploration. Two case studies were presented illustrating how geochemical and mineralogical data from orogenic gold and porphyry copper deposits can be integrated to better define hydrothermal alteration systems. A third case study examined the use of selective extractions for the analysis of a mineralogically complex intrusive-related gold deposit. The final case study illustrated how whole-rock data can be used to calculate normative mineralogy for the estimation of by-product mineral resources in a lithium pegmatite deposit.
A second presentation, entitled "Mineralogical vectoring in the Central Victorian Goldfields" highlighted publicly-available geochemical and mineralogical data from the Bendigo, Ballarat, Fosterville, Costerfield, and Maldon goldfields. The data define ferroan carbonate, sericite and sulphide (pyrite and arsenopyrite) alteration haloes, the presence and intensity of which can be used to vector within the hydrothermal alteration systems.
Join Dennis and the other presenters as they discuss applied mineralogy to define hydrothermal alteration for mineral exploration.
Links to YouTube videos and copies of both presentations will soon be available through the AIG web site.
