The Linda Zinc EL in the Flinders Ranges covers 190 km2. The project is underlain by Neoproterozoic to early Cambrian sedimentary rocks. Stelar consider that this area is prospective for Mississippi Valley type (MVT) and Beltana-Kipushi type zinc-lead mineralisation as well as Zambian-style copper mineralisation.
The project area occurs on a group of structures which host a diapir on the southeast margin of the tenement. The diapir and associated faults are a potentially important fluid pathway for mineralisation.
Potential host rocks are known in the Cambrian limestone sequence which hosts significant zinc mineralisation discovered by BHP in the 1980s inside the Linda tenement. The geological setting is similar to that at the high-grade Beltana zinc deposit in the Flinders Ranges. Beltana has strong similarities to the high-grade zinc-copper-lead deposits in the Central African Copperbelt such as Kipushi. Stelar is also applying a Beltana-Kipushi model to exploration on this tenement.
The Tindelpina Member of the Tapley Hill Formation has been shown to contain significant Zambian-style copper mineralisation by recent drilling completed by Taruga Minerals. This unit has been mapped on the Linda tenement. Its prospectivity is supported by known copper occurrences inside the tenement.
