Sheffield Resources has added a further one million tonnes of resource at its Eneabba mineral sands project in Western Australia.
The company reported a maiden mineral resource of 52.2 million tonnes, at 2.1% heavy minerals at its Drummond Crossing deposit, adding 1.07 million tonnes of heavy minerals to the overall Eneabba project.
Drummond Crossing is one of six deposits identified within the Eneabba project, of which five are currently included in the project's resource inventory.
The company said the Drummond Crossing resource adds 150,000t of zircon, 107,000t of rutile, 570,000t of ilmenite and 38,000t of leucoxene to the Eneabba project inventory that currently stands at 6.8 million tonnes of contained heavy minerals, of which 5.8 million tonnes is valuable.
Sheffield Resources managing director Bruce McQuitty said Drummond Crossing is an important addition to near-surface HM resources in the Eneabba region.
"Drummond Crossing is the fifth resource of over one million tonnes of contained heavy mineral we have added to our Eneabba project, and is a further example of the near-surface high-value zircon and rutile-rich heavy mineral sand deposits we are targeting," McQuitty added.
McQuitty noted that the company has identified four new targets of this style of mineralisation, representing an opportunity to further grow the Eneabba project.
"While the Dampier mineral sands project remains Sheffield's principal focus, we will continue to pursue low-cost opportunities like this to build a strategic resource base in a proven mining district," McQuitty said.
The company undertook a regional surface sampling programme to identify additional shallow to outcropping dunal heavy mineral sands HMS mineralisation in July 2013.
The next phase of work will include mineral assemblage determinations on the heavy mineral concentrate from the surface samples.
Additional follow-up surface sampling is planned for the first quarter of 2014.
