South Australian Projects
Located some 3.5 hours’ drive north from Adelaide, the Arden Project boasts a large relatively-unexplored area of 1,664km² highly-prospective for sedimentary-exhalative (SEDEX) mineralisation. Results from initial exploration at Ragless Range, Kanyaka and Radford Creek targets have unearthed promising prospects for large scale copper and zinc deposits.
The project is located in the base-metal mining region of South Australia, which is host to numerous large base-metal deposits including the Beltana zinc deposit, the Angas zinc deposit and the Kanmantoo copper deposit.
The Sedex potential was initially discovered by Kennecott (Rio Tinto Group) between 1966 and 1972, identifying anomalous Sedex-style zinc mineralisation up to 40m wide and with a potential for over 10km of strike. However, since 1980 the area has been the focus of regional diamond exploration, and as such the Sedex horizon at the Ragless Range Target had not been explored. The Company has moved quickly to realise the project potential, undertaking reconnaissance field mapping, rock-chip sampling, a reinterpretation of historical data and an aeromagnetic survey before intiating its maiden drill programme in August 2018. Arden enjoys access to world-class infrastructure including the railway, grid power and access to port.
2019 Gravity Survey
A detailed ground-gravity survey was completed at Arden: the high-resolution survey delineated a significant gravity anomaly extending over 2km at the Ragless Range prospect, coincident with areas of anomalous zinc values at surface. The gravity anomaly may be indicative of thickened mineralised horizons of the high-density, high-grade zinc mineral smithsonite that was identified in drill-hole RRDD007, and provides a direct targeting tool for the next phase of drilling.
2018 Drilling Programme
Maiden drill programme at Arden intercepted base-metals mineralisation in all 10 drill-holes with up to 3 horizons of SEDEX zinc mineralisation identified at the Ragless Range Prospect within the Arden Project, extending over 3km of strike and open in every direction. The best intersection was from drill-hole RRDD-007: 8.15m @ 7.52% Zn & 0.02% Pb from 57.65m, including 3.65m @ 15.47% Zn & 0.02% Pb from 62.15m.
