In a pursuit to broaden her horizons, Lerisia accepted an expatriate position in Mali at the end of 2012. This offered her the opportunity to gain more extensive experience in gold metallurgy and processing, covering both oxide as well as refractory gold. During her time in Mali, Lerisia was also afforded the opportunity to use her technical capabilities and process optimisation experience to branch into finance and focus on overall business improvement. In this role, she was mainly responsible for coordinating cross-functional work teams to develop & optimise business plans, and to identify, evaluate and implement improvement projects with clear and quantifiable impact on the bottom-line.
