Greatland Managing Director, Shaun Day, commented:
“O’Callaghans is a globally significant tungsten and base metals deposit that presents latent value and
optionality within Greatland’s portfolio, particularly in the strong prevailing tungsten market conditions.
“Greatland’s first Mineral Resource Estimate for the deposit delineates a high grade 70 million tonne
resource, the vast majority in the high confidence Indicated Resource category, providing a clearer basis
to understand the scale and quality of this strategic asset.
“O’Callaghans is one of the world’s largest high grade tungsten deposits, in close proximity to our Telfer
mine which provides the potential to benefit from sharing of some of Telfer’s non-processing infrastructure.
While our primary focus will remain Telfer and Havieron, we are considering appropriate options to
demonstrate and enhance the project’s value within the Greatland portfolio.”
