The majority of the resource estimate incorporates veined and disseminated chalcopyrite and carrolite sulphide mineralization, with oxide malachite and heterogenite
mineralization predominantly in the footwall zone, beneath the base of the pit, and near surface on the hanging wall.
At the RSF prospect, mineralisation encountered to date is predominantly oxide and occurs as disseminations and segregations of malachite and heterogenite
in residual highly weathered dolomitic shales, siltstones, and breccias.
Economic mineralization in the oxide zone is primarily malachite, pseudomalachite and chrysocolla with heterogenite
as the major oxide cobalt mineral.
The mineralization is mainly chalcopyrite and carrolite with occurrences of malachite and heterogenite
(non-sulphide copper and cobalt minerals respectively) visible in the upper portions of the holes.
The mineralization is mainly chalcopyrite and carrolite, with locally trace occurrences of malachite and heterogenite
(non-sulphide copper and cobalt minerals respectively).
Supergene minerals malachite and heterogenite
are observed overprinting and replacing the earlier sulphide phases.
