By Reuben Adams THE arrival of three seafloor production tools (SPTs) at Duqm Port in Oman for extensive wet testing represents a major milestone for Nautilus Minerals’ Solwara 1 project. The SPTs will cut and extract high grade copper and gold from the seafloor at the Solwara 1 project site in the Bismarck Sea off the coast of Papua New Guinea, with production to start in the first quarter of 2018. The SPTs were designed and assembled in Newcastle upon Tyne by UK company Soil Machine Dynamics, which was awarded the contract for the world-first deep sea mining vehicles in 2007. The SPTs and associated equipment weigh more than 1000t. The wet testing would examine control systems operations and feedback;...

By Samantha James AUSTRALIAN iron ore prices crossed the $50/t threshold in February, a price not seen for more than three months. Prices were sub $40/t across December and January but a rally in Chinese steel demand in February was attributed to the end of China’s lunar holiday and the restart of steel production. However, Argonaut Securities analyst Helen Lau said it was a seasonal uptick, and that an upsurge in demand for construction steel products would be hampered by excess supply. “Low steel inventory, seasonal demand rebound after Chinese New Year and increasing utilization rate at blast furnaces has resulted in a rebound in steel and iron ore price,” she said. “We believe this rebound in steel prices and...

By Samantha James THE inevitable mothballing of coal mines around the world will force the industry to question who is responsible for the rehabilitation of the abandoned sites, and what best practices can reduce the long term impact on native environments. When left untended, open pits below groundwater level fill with rain and groundwater to become pit lakes, and large regions with abandoned, un-reclaimed areas turn into lake districts. Above groundwater, pits are left as large holes in the landscape known as final voids; they prevent rehabilitation of native plants and animals or reuse as agricultural land. NSW is feeling the impact of final voids keenly, with more than 500 derelict mines across the state. Further issues are anticipated with the...
