Ok Tedi Mining Limited’s (OTML) Senior Aquatic Ecologist, Gilton Alimaka, recently participated in an intensive 24-day training in Perth Western Australia, conducted by Sustainable Leaders in Resources (SLR) Consulting.
The training was focused on laboratory processing, taxonomic identification, and statistical methods for assessing aquatic organisms (micro and macro invertebrates) and ecosystem.
The training was aimed at enhancing OTML’s ecological team’s skills in analysing macroinvertebrate samples, accurately identifying species, and using statistical tools to assess environmental data.
This acquired knowledge is crucial for monitoring water quality and ecosystem health, particularly in areas affected by mining.
OTML Manager Environment Department, Erizo Kepe said, “Aquatic macroinvertebrates, such as mayflies and snails, are vital indicators of water quality. The ability to identify these species accurately helps in assessing environmental health, especially in ecosystems impacted by mining.”
The training included hands-on exercises with real data, teaching participants statistical methods like Principal Component Analysis (PCA) and Non-metric Multidimensional Scaling (NMDS) to analyse ecological patterns and track environmental changes.
Ms Kepe said, “This training strengthens OTML’s ability to monitor the environmental impact of mining, assess water quality, and predict long-term effects. The new skills also support OTML’s commitment to scientific accuracy, regulatory compliance, and environmental best practices.”
By sharing this knowledge with colleagues, the training creates a culture of continuous learning thus improving the team’s overall capability to address environmental challenges. OTML’s enhanced ecological expertise contributes to better decision-making, sustainable practices, and a stronger reputation in the industry.
The training is part of the Environment Department’s ongoing effort to upskill its team in their specialised scientific fields to operate more efficiently while reducing dependency on external expertise.
