Mineral Resources Statement

A 2.2 million ounce Mineral Resource has already been defined at the Mallina Gold Project which excludes the Hemi discovery.

In April 2020, we updated the Mineral Resource for the Mallina Gold Project to 37.4 million tonnes grading 1.8g/t gold for 2.2 million ounces. The majority of this estimate lies within shear-hosted deposits with Toweranna being the only intrusion-hosted resource defined to date. A table outlining this April 2020 Mineral Resource is contained below. After an extensive drilling program, a high quality maiden Mineral Resource Estimate for Hemi is expected to be completed by mid-2021. For the latest information on regional exploration, please view our ASX Releases, Corporate Presentations pages and Videos.

Within the same 1,500 km² tenement package it also controls base metals resources (zinc, lead with associated silver) and a lithium exploration prospect.

In addition to the hard-rock gold resource, the company has three conglomerate gold targets where gold nuggets have already been discovered.
