Kanmantoo Mine Lease
Overview
The extensive copper exploration targets on the Kanmantoo mining lease include:
- Along strike and down-dip extensions of the Kavanagh and Nugent Cu-Au Mineral Resources
- The Emily Star down dip extension
- Valentine, Critchley and Paringa
- The Coopers and North Kavanagh deposits to the north of the Kavanagh underground development
These are classified as the North and South copper hubs, where exploration activities will be targeted as underground development allows.
Key Facts
- The Kanmantoo Trough of the Cambro-Ordovician Kanmantoo Province of south-east South Australia is host to numerous Cu, Pb, Zn, Ag, Au, As, Bi deposits over its 300km length, of which the Kanmantoo Cu-Au deposit is the largest known.
- The Delamerian Orogen has affected the Kanmantoo Group with three episodes of deformation between 514 and 490 Ma (Foden, et al., 2006). At the Kanmantoo deposit, D2 is the dominant deformation event with upright north-south folds with shallow southerly plunges and a dominant axial-plane parallel S2 fabric (Offler & Flemming, 1968).
- Magmatism within the Kanmantoo Province can be correlated with each of the three Delamerian age deformation events, with S-type intrusives dominant with D1, S- and I-type intrusives with D2, and A-types intrusives post deformation (Foden et al, 2020).
- The main copper orebody at Kanmantoo (Kavanagh) is discordant both to bedding and to all mineral lineations and is partly sympathetic with the axial planar schistosity of the D2 Kanmantoo Syncline which averages ~650 -> 0840.
- In 2025, 60,000m of drilling is planned across both grade control infill drilling and resource expansion targets.
