Auckland Discussion Group Meeting 19 June 2018


Lauren will present an overview of her PhD research on the relationship between gold and tungsten mineralisation in Otago. The talk will focus on the Macraes mine, examining how the mineralisation style differs between the two metals within the deposit. She will discuss the use of portable XRF in characterising tungsten mineralisation, and how this technique was used to develop a model of the mineralisation within the open pit. The talk will end with a discussion of how the Macraes model can be extrapolated across Otago with respect to other gold/tungsten deposits.


Lauren Farmer earned her B.Sc. and M.Sc. from the University of Southampton (United Kingdom) and her PhD from the University of Otago. Her Master’s thesis examined the clay mineralogy of the Alpine Fault Zone. Her PhD project focused on the world-class Macraes deposit in Otago, and combined elements of structural geology, geostatistics and geochemistry to characterise the tungsten mineralisation. Since graduating in 2016 she has worked as a consultant geologist on projects both globally and within New Zealand.
