Algae and mining: A new frontier in sustainable site rehabilitation

Algae might seem an unlikely candidate to help transform Australia’s post-mining landscapes, but a new CSIRO -led project suggests these tiny aquatic organisms could provide sustainable futures for mine sites, surrounding ecosystems, and local communities. Looking down the microscope at the microalgae Nannochloropsis Australia’s mining sector is approaching a crossroads—where economic legacy and environmental responsibility must find common ground. A new CSIRO -led study, supported by the Cooperative Research Centre for Transformations in Mining Economies (CRC TiME), suggests that one of the most promising bridges between these imperatives may come from an unexpected source: algae. Though small in stature, algae are emerging as giants in their potential to transform post-mining landscapes. The study, developed in partnership with the University of Queensland and Murdoch University , proposes that algae-based technologies could reduce mining’s environmental footprint while seeding new...

Oz Minerals targets Cambodia for expansion

The radically contracted Australian miner OZ Minerals is continuing to explore opportunities in South East Asia and is undertaking final drilling at Okvau in north east Cambodia before producing an initial resource estimate. Recent drill results at Okvau included one hole from surface to almost 400 m that gave series of seven significant intercepts, the best two being 9m from surface of 4.82 g/t and a deeper hit of 10m @ 5.99 g/t gold.

However the company sold its 75% interest in the Thai Chatree joint venture with Thai Global Ventures to Owen Hegarty's Tigers Realm Minerals Pty Ltd for cash and shares. It retains Thai tenement applications for greenfield exploration.
