The Weld Range tenement M20/118 is one of Atlas’ two high grade projects in the Mid West of Western Australia. The project, in the Wilgie Mia area of the Weld Range, includes particularly high grade hematite mineralisation which has historically been mined for ochre, and mined on a commercial scale for specularite to be used in paint manufacture. A small program of RC drilling by Atlas in 2008 confirmed the extent and tenor of iron mineralisation, with assays as high as 68% Fe.

The Weld Range region contains greenstone belts, consisting of metavolcanic - metasedimentary sequences including BIF horizons, and granitoids. The tenement contains two main prospects, named Wilgie Mia and Little Wilgie Mia, which are considered to be within the one main banded iron formation (BIF) unit. There are also two parallel iron-enriched BIF units which lie proximal to the Wilgie Mia prospect. Mineralisation is considered to be a combination of goethite and hematite (seen in excavations as red ochre) created through the supergene enrichment of BIF. From mapped iron enriched outcrop, strike lengths of the various mineralised lenses vary from a few metres to 520m with thicknesses varying between 40 and 50 metres. The strike of the deposit is NE to SW with the dip generally being 80^o to the SE.

The project has an exploration target of 15 to 20 million tonnes at between 60% and 66% Fe.

Atlas is working with the Wajarri People to assist in the protection of the nearby Wilgie Mia Aboriginal ochre mine.
