Lachlan has extensive experience in technology development and innovation, having led the development of the Toowong Process through the phases of conceptual design, feasibility, engineering, and commercialisation.

Carla has over 25 years’ experience in metallurgical testing, plant design and processing of a wide range of commodities.  She has extensive experience with base metal flotation and processing of gold ores. Carla specialises in working with clients to identify the best process solution for their project and taking this through to the plant design phase. She holds a Bachelor of Engineering (Honours) in Mineral Processing from the University of Queensland.

Maedeh has PhD and M.Sc. in mineral processing (flotation) and B.Sc. in mining engineering with over 14 years’ experience in the mining industry with a focus on the base metals beneficiation. She has worked as a process engineer for different project phases from scoping to conceptual, pre-feasibility and feasibility and trade-off studies within a multi-discipline engineering team. Over the years, she became an expert in flotation with a strong focus on flotation modelling and simulation, surface chemistry and process mineralogy.

Dylan is a Senior process engineer with over 8 years’ experience in both the mining and wastewater sectors. Dylan manages the ion exchange technology programmes at Core and is a key member of the Toowong Process team with expertise across arsenic and antimony hydrometallurgy. Dylan is also adept at METSIM, with steady state modelling an integral part of the engineering studies Core executes.

Danielle has over 10 years’ of hands-on experience in the minerals processing industry, specialising in base metal concentrators. Her expertise spans production, planning, and project metallurgy roles. She also has extensive experience in flowsheet development, test work management, pilot plants, and commissioning. Danielle’s true passion lies in process optimisation projects, where she thrives on finding the best solutions for her clients, incorporating innovative and cost-effective technologies to enhance performance and reduce costs.

David joined the Core team as a Senior Metallurgist in 2023 and holds a PhD from the University of Newcastle in Chemical Engineering with a focus on gravity separation and physical beneficiation. He has worked in both academic and industry roles, with experience across a range of disciplines including mineral processing, hydrometallurgy, pyrometallurgy and mine water treatment/remediation. David has a strong interest in developing new and sustainable processes for critical minerals to support the energy transition.

Di holds a PhD in Mineral Processing. She has a strong background in research, technology development and applications for the mining industry. As a metallurgist/process engineer at Core, she designs and manages metallurgical projects for various mining companies, with a focus on base metal flotation, gold ore processing and hydrometallurgy processes. Prior to this, Di worked as a process engineering specialist in developing novel technologies in acid mine drainage management and tailings dewatering. Di has a strong interest in advancing new technologies to tackle industry challenges to meet the demands of complex ore bodies while striving for sustainable solutions.

James has a Bachelor of Engineering with majors in Chemical and Metallurgical engineering from UQ and over 7 years’ experience in metallurgy. He started out as a technician in fundamental pyrometallurgical research, producing thermodynamic data for use in modelling programs. As a metallurgist he has managed day to day operations in a base metal sulphide concentrator, as well as conducting on site testwork for new ore types and alternative reagent identification.
