Thor Mining provides Alford East update

Published by , Editor
Global Mining Review,

The directors of Thor Mining Plc have provided an update on the Alford East Copper-Gold Project, South Australia, Australia.

Project highlights

  • Significant intercepts including:
    • 21AED001: 32.9 m at 0.4% copper (Cu) and 0.31 g/t gold (Au) from 81.5 m.
    • 21AED002: 59.9 m at 0.3% Cu from 21.9 m.
    • 21AED003: 32.4 m at 0.2% Cu and NSR Au from 15 m.
    • 21AED004: 55.9 m at 0.53% Cu from 7 m, including:
      • 11.7 m at 1% Cu from 17.3 m, including:
      • 5.7 m at 1.23% and 0.16 g/t Au from 17.3 m.
    • 21AED005: 72.7 m at 1% Cu and 0.19 g/t Au from 6.3 m, including:
      • 18.2 m at 2% Cu and 0.34 g/t Au from 15.8 m.
  • A robust 3D geological model generated from recent drilling data high-lights key structural and lithological controls on mineralisation and potential high-grade target zones.
  • Initial hydrometallurgy trialling of an environmentally friendly glycine lixiviant shows positive gold and copper recovery.
  • Phase two diamond drilling program is being designed, including continuing hydrogeology and hydrometallurgical studies.

Nicole Galloway Warland, Managing Director of Thor Mining, commented: “The success of our first phase of drilling, with significant uplift in copper and gold grade, adjacent to the Netherleigh Fault, is very exciting and suggests the potential for extended zones of higher-grade copper and gold along strike and at depth.

“Demonstrating Thor's greater understanding of the geological and structural constraints through the new geological modelling is critical to the overall project's development, especially as we plan our second phase of drilling and progress our hydrometallurgical studies.

“These favourable initial hydrometallurgical results for the metal recovery for both copper and gold using a socially and environmentally friendly solution 'glycine' rather than conventional acid in-situ recovery (ISR) is significant, as Thor strives towards the in-situ assessment of the Alford East Project.”

Next step

Based on the new geological model, approximately 10 diamond drill holes have been designed to test potential high-grade zones:

  • Along strike and up-dip of deeply weathered zones.
  • Targeting controlling key structures including the Netherleigh Park Fault at depth especially where there are large gaps in existing data.
  • Targeting intersection of SMS and Liaway offset Fault.
  • Targeting intersection of Netherleigh Park Fault and Liaway Fault.
  • Targeting subordinate splays off Netherleigh Park Fault, where there is evidence of a deep weathering trough.

In addition, hydrogeological water bores and pump testing is in planning to determine aquifer connectivity between holes, with initial focus in the northern area of the mineralisation.

Concurrent to drilling, hydrometallurgical work will continue to investigate and optimise both copper and gold metal extraction using environmentally friendly lixiviants.
