PhD Opportunity on the enhanced geological and geochemical vectoring tools toward Au–Ag mineralization in the Cerro Negro district, Patagonia, Argentina

A PhD project is available within the ARC Transforming the Mining Value Chain (TMVC) Industrial Transformation Research Hub, which is hosted at the University of Tasmania. The TMVC draws on expertise from personnel within CODES (Centre for Ore Deposit and Earth Sciences) and Engineering.

The Project:

The Cerro Negro epithermal district is located proximal to the north-western margin of the Deseado Massif, Patagonia, Argentina. Gold–Ag-bearing low sulfidation epithermal veins have been identified in the Eureka, Vein Zone, and Mariana Complexes. Cerro Negro is considered to be somewhat barely eroded thereby potentially limiting the exposure of the epithermal veins beneath near‐surface. Furthermore, vein exposures are limited due to post-mineralization volcanic cover. The recently discovered, blind gold-rich Silica Cap vein complex encourages further exploration focused on locating blind ore-bearing veins.

This PhD project will focus on studying three key Au–Ag-rich epithermal systems in the Cerro Negro district (i.e. the Silica Cap, Eureka, and Marianas systems). The candidate will use a combination of field mapping, core logging, hyperspectral, microanalytical (e.g., SEM, CL, LA-ICPMS), whole rock geochemical and geochronological techniques to characterise epithermal systems. The proposed project encompasses the study of surface and sub-surface lithology, hydrothermal alteration assemblages, and mineralized vein and breccias; with strong emphasis on exploration and genetic significance of epithermal systems. A major aim is to test and improve those vectors towards mineralization proposed during our current research project and as well as develop new ones.

Duration: 3 years, with the possibility of a six month extension.

Scholarship: The candidate will be required to be self-supporting, or to be successful in attaining a UTAS Scholarship (2019 rate of AUD 27,596 pa).

Research Costs: funded by Newmont Goldcorp Corporation
