“An advanced large multi-commodity copper project with mineralisation delineated over a 9.5km strike length”
The majority of copper-gold-molybdenum mineralisation at Productora is hosted in a structurally focused breccia and fracture network developed within a larger body of K-feldspar-tourmaline-magnetite hydrothermal breccia. Structurally-focused mineralised breccia zones are evident trending broadly sub-parallel to the Productora fault zone (NNE).
The association between mineralisation, breccia zones and manto horizons shows that an interplay between units with significant primary permeability (mantos) and fault-related secondary permeability (breccias) exert a critical control on the distribution of mineralisation.
Mineralised breccias are clearly visible in both RC drilling and in diamond core. The intensity of brecciation, alteration and sulphide mineralisation is generally greater within higher-grade domains.
Sulfides comprise pyrite, chalcopyrite, bornite and molybdenite developed as breccia, vein and cavity fill, as well as disseminations within the brecciated host rocks. This sulphide distribution creates centimetre to metre-scale higher-grade patches enclosed by moderate-grade disseminated sulphide minerals.
