Deposit type

  • Banded iron formation hosted

Summary:

MAXWELLS
The Maxwells deposit is hosted within the lower ‘Maxwells’ member. The Mount Belches group is located in the southern Eastern Goldfields Superterrane, Yilgarn Craton, Western Australia.

The iron formation is a silicate/oxide-facies unit with over printing sulphides, which has undergone metamorphism (upper-greenschist facies) and deformation (two generations of folds). The gold deposits are hosted in both the hinge zone and along the limbs of a regional scale, chevron folded BIF package.

Gold dominantly occurs as inclusions of native gold and/or electrum within or around pyrrhotite, magnetite, and arsenopyrite, and economic mineralisation is typically restricted to the BIF horizons.

The Maxwells resource extent consists of 2020m strike; 440m across strike; and 790m down dip and open at depth.

COCK-EYED BOB
The Cock-eyed Bob is hosted within the upper ‘Santa Clause’ member of the Banded Iron-Formation (BIF) of the Mount Belches group. The Mount Belches group is in the southern Eastern Goldfields Superterrane, Yilgarn Craton, Western Australia.

The iron formation is a silicate/oxide-facies unit with over printing sulphides and has undergone metamorphism (upper-greenschist facies) and deformation (two generations of folds). The gold deposits are hosted in both the hinge zone and along the limbs of a regional scale, chevron folded BIF package.

Gold dominantly occurs as inclusions of native gold and/or electrum within or around pyrrhotite, magnetite, and arsenopyrite, and economic mineralisation is typically restricted to the BIF horizons.

The Cock-Eyed Bob complex’s resource extent consists of 1480m strike; 416m across strike; and 660m down dip and open at depth.

SANTA
The ‘Maxwells’, CEB and ‘Flora Dora’ deposits are hosted within the lower ‘Maxwells’ member of The Mount Belches group and the ‘Santa’ deposit is hosted within the upper ‘Santa’’ member both members are located in the southern Eastern Goldfields Superterrane, Yilgarn Craton, Western Australia.

The iron formation is a silicate/oxide-facies unit with over printing sulfides and has undergone metamorphism (upper-greenschist facies) and deformation (two generations of folds). The gold deposits are hosted in both the hinge zone and along the limbs of a regional scale, chevron folded BIF package.

Gold dominantly occurs as inclusions of native gold and/or electrum within or around pyrrhotite, magnetite and arsenopyrite, and economic mineralisation is typically restricted to the BIF horizons.

The last reported Santa resource model was extended towards south and west to include nearby Flora Dora deposit. The Santa resource extent consists of about 2900m strike; 1300m across strike; and 500m down dip and open a depth.
