Glencore has conducted an extensive 2D seismic survey to identify untapped ore resources in the Mount Isa area which could be economically mined and processed in years to come.
‘Vibe trucks’ carried out the work across Mount Isa Mines ground and adjacent exploration permits throughout October and early November.
Conducted in collaboration with NQ Resource Development and Exploration, and in partnership with HiSeis, the 2D survey covered about 60 line kilometres of measurements
Reporting the work in its Resourceful e-newletter, Glencore said the survey involved a geophones, which are very sensitive microphones and controlled vibration sources, in the form of ‘vibe trucks’.
The geophones pick up the vibrations as they move through the ground and reflect off various geological features such as faults and rock type changes.
Glencore senior geologist – regional exploration Alex Brown said the survey was aimed at providing information on the geologic framework in which the Mount Isa Mines operations sat, at a resolution and depth that could not be achieved with other techniques.
“We surveyed a 60 line kilometre area spanning from Mica Creek to Spear Creek, which afforded us good coverage over the mine environment, as well as adjacent exploration permits,” he said.
“Combined with widespread exploration drilling completed over the last 60 years, the survey will help us improve our knowledge and modelling of important geological features, particularly in areas without many deep drill holes.
“As the survey covered an extensive area, our team had to collaborate with a number of internal and external stakeholders to ensure appropriate hazard identification and guarantee project impacts on the operations were minimal.”
Results from the 2D survey are expected in the New Year.
Glencore said these results would be used to guide future business decisions, including whether a more comprehensive 3D survey is warranted.
