WIMMERA MINERAL RESOURCE ESTIMATE
Iluka Resources is pleased to announce inaugural Mineral Resource estimates fortwo of the company’s
Wimmera heavy mineral (HM) deposits, WIM100 and WIM50 respectively, with the latter split into
WIM50 and WIM50 North sub-areas. These deposits are located along the south eastern margin of the
Murray Basin geomorphological province in the state of Victoria, Australia.
• The WIM100 deposit contains an Indicated Mineral Resource estimate of 340Mt grading 4.7%
HM for 16Mt of contained HM; and an Inferred Mineral Resource estimate of 100Mt grading
3.4% HM for 3.4Mt of contained HM – totalling 440Mt grading 4.4% HM for 19Mt of contained
HM. WIM100 is the initial, primary focus of Iluka’s Wimmera project, which is currently the
subject of a preliminary feasibility study.
• The WIM50 deposit contains an Inferred Mineral Resource estimate of 360Mt grading 4.1%
HM for 15Mt of contained HM.
• The WIM50 North deposit contains an Inferred Mineral Resource estimate of 580Mt grading
5.7% HM for 33Mt of contained HM.
The combined Indicated and Inferred Mineral Resource estimate for the WIM100 and WIM50 deposits
is 1.38Bt grading 4.9% HM for 67Mt of contained HM, estimated in accordance with the guidelines of
the JORC Code (2012 edition).
Iluka’s Managing Director, Tom O’Leary said “The Wimmera region in Western Victoria has the
potential to be a multi-decade future source of critical minerals, in particular zircon and rare earths.
Deposits in this region have a range of technical challenges relative to traditional mineral sands
developments; and, over the last decade, Iluka has invested material energy and resources in
progressively overcoming these challenges. The key challenge relates to impurities in the region’s
zircon which, absent a processing solution, render it ineligible for most end-markets, including
ceramics. Iluka’s declaration of resources at the WIM100 and WIM50 deposits reflects our confidence
in progress toward a processing solution, with larger scale piloting currently underway.”
This document was approved and authorised for release to the market by Iluka’s Managing Director.
