Kevin Ng, M.Sc. Student, McGill University


Kevin is an economic geologist specializing in geochemistry while also being passionate about fieldwork and mapping projects. In particular, he is intrigued by various types of gold mineralization, particularly in epithermal-porphyry systems and orogenic gold deposits. He is currently an M.Sc. student in Professor A.E. Williams-Jones’s Hydrothermal Geochemistry Group at McGill University, researching the epithermal gold-silver deposit at Brucejack, in BC’s Northwest Region. He gained his industry experience as an exploration geologist with Newcrest Mining, participating in near-mine exploration programs in 2021 and 2022. Prior to his admission into McGill, he completed his B.Sc. (Geology) at the University of Hong Kong in 2019 and worked on a research-based project studying the genesis of an orogenic gold deposit in Giro, Congo.

Project: Fluid Evolution of Ore-bearing Veins in Bonanza Grade Epithermal Gold-Silver Deposit in Brucejack, Northern BC

The overreaching objective of this project is to determine the physico-chemical conditions (e.g., P-T conditions, salinity and fluid chemistry) that occurred in hydrothermal fluids during colloid formation, transportation and flocculation at Brucejack and to identify the geological processes that led to this phenomenon. Vein paragenesis in the area is complex and involves earlier quartz-bearing veins that were crosscut by multiple generations of calcite veins. It is therefore important to determine whether ore formation was part of the evolution of a single fluid or was sourced from another fluid.

A combination of various analytical techniques will be performed to achieve the above objectives. These techniques include optical and SEM cathodoluminescence microscopy, in-situ major, minor and trace element analysis of different minerals, fluid inclusion microthermometry coupled with RAMAN spectroscopy and thermodynamic modelling.
