“Since then we haven’t had any overloads, and typically we have 100 overloads per year”, Gerard said.

The Lihir operation is located on Aniolam Island in the New Ireland Province of Papua New Guinea. Since starting production in 1997, the mine has produced more than 10Moz of gold.

PETRA Data Science stated that this is a fantastic example of digital transformation delivering tangible results through collaboration and diversity of stakeholders, and offered congratulations to all parties involved. The company’s managing director and principal, Dr Penny Stewart, also attended the Unearthed Melbourne event. In her role as mentor, she shared her knowledge and experience in applying engineered data science to mining industry challenges with the teams of innovators, entrepreneurs and startups.

As part of the challenge, over 100 participants had 54 hours to create novel solutions to four real-world challenges, with operational data sets provided by Newcrest Mining.
