Wedderburn

Overview

The Wedderburn HMS Project is a shallow lying HMS deposit, with a low strip ratio, that has a Mineral Resource Estimate for Wedderburn is 223Mt @ 2.9% THM (JORC 2012, Indicated and Inferred).

Location

The Wedderburn project is centered approximately 25km northeast of the township of Charlton, Victoria. The project area is serviced by:

  • Existing roads
  • Existing water supply and power-related infrastructure
  • Port options readily accessible through local and regional rail

Resource Geology

The Wedderburn HMS Project a shallow lying HMS deposit, with a low strip ratio. WIM has completed over 6,000m of air core drilling and has defined a mineral resource estimate of 223Mt of ore, containing 2.9% total heavy mineral (THM) (JORC 2012, Indicated and Inferred).

The bulk of the mineralization at Wedderburn is hosted within a lower energy, sub-wave base depositional environment within the Loxton Parilla Sands.

Detailed cross-section interpretation completed by WIM led to the development of a ‘stacked sequence’ model, whereby it is interpreted that there have been several phases of marine transgression and regression, resulting in several offshore and poorly developed foreshore sands deposited in a stacked sequence.


The local geology of the Wedderburn project appears to be controlled by several basement structural features, including a major fault and a complex intrusive history, and WIM has interpreted these to control the RL (depth) of the mineralisation across the project area.

JORC Resource

In 2015, WIM engaged mining experts Optiro Pty Ltd to undertake a resource estimate update for the project. The Global Mineral Resource Estimate for Wedderburn is 223Mt @ 2.9% THM (JORC 2012, Indicated and Inferred). Within the central block, the resource contains 94Mt @ 3.1% and contains 23.5% zircon. Coupled with a strip ratio of 0.5:1, the Wedderburn Project is shaping up to be an attractive addition to WIM’s expanding resource portfolio.

The table below outlines the 2015 Resource Estimate (by area and domain), reported above a cut-off grade of 1% THM:

WORK COMPLETED

WIM has completed significant resource definition drilling over the project and has developed a geological model that underpins a Resource Estimate.
