Ambient Noise Tomography for Copper-Gold Porphyry Exploration: Reko Diq, Balochistan, Pakistan

The Reko Diq Project in Balochistan, Pakistan, home to one of the world's largest undeveloped copper-gold porphyry deposits, was the focus of Barrick and RDMC's deployment of ExoSphere's real-time 3D subsurface imaging across 1,150km2 to advance orebody knowledge, identify copper-gold porphyry mineralization, and accelerate resource development at the project.

The Reko Diq Project boasts indicated and measured resources of 3,653 Mt at 0.42% Cu and 0.25 g/t Au within the Western Porphyry Complex (WPC), and 277 Mt at0.45% Cu in the Tanjeel deposit. Open-pit mining operations are anticipated to commence in 2028.

ExoSphere was deployed using one hundred Geodes in sequential 100-node grids across the project area, facilitating continuous data acquisition and real-time quality control via ExoSphere's cloud interface. The 3D seismic data was processed using Fleet Space's proprietary automated system to generate detailed 3D shear velocity models of the subsurface. Results of ExoSphere's deployment at Reko Diq included several new findings from its imaging of major geological structures linked to mineralization, specifically the D1(NW-trending) and D2 (NNE-trending) structural trends, identifying potential 'hypogene feeder' zones associated with hydrothermal alteration and copper-gold porphyry mineralization, and more.
