Western Australian gold explorer De Grey has announced major strike and depth extensions at the Eagle and Diucon deposits, enhancing resource growth at the Hemi project in the Pilbara.
According to De Grey, the results provide the potential for increased scale of the planned Diucon-Eagle open pits, and enhance underground mining potential.
“Following completion of resource definition drilling, the focus has shifted to exploration drilling,” De Grey general manager exploration Phil Tornatora said.
“This is already paying dividends, with significant extensions to mineralisation at depth at Eagle and along strike at Diucon.
“In addition to potential resource increases, deeper drilling at Hemi will support early conceptual studies into potential underground mining in the future.”
The higher grade mineralisation at Eagle and Diucon are associated with major shear zone inflections, and include quartz veins containing visible gold.
De Grey has been developing the Hemi project since late-2019 after making a large-scale, high-value, near-surface gold discovery at the area in the Mallina Basin.
“The shallower Diucon extensions have the potential to result in an expansion of the Diucon-Eagle open pit shell outline,” Tornatora said. “RC drilling is also currently taking place on the Antwerp trend, aiming to define an initial resource.”
In February this year, De Grey appointed Peter Holmes as the Hemi project’s new director. Holmes joined the project with 30 years of experience in the gold industry, including construction and commissioning large scale gold projects.
