Talisman Mining Reports Positive Results from Walkers Hill Project RC Drilling Program

Strategic Insights

— 2 min read

Talisman Mining's recent RC drilling program at its Walkers Hill Project in New South Wales has yielded encouraging results, with four of the five holes intersecting broad zones of low-grade gold mineralisation. The drilling program aimed to test historical near-surface mineralisation and a significant Pole-Dipole Induced Polarisation (PDIP) chargeability anomaly. The results have provided a clearer understanding of the gold mineralisation at the Sheepyard Prospect and have highlighted the potential for higher-grade mineralisation in the area.

Key Takeaways:

  • The RC drilling program at the Walkers Hill Project has delivered wide zones of shallow, low-grade gold mineralisation in four of the five holes drilled, including intercepts of up to 42m at 0.44g/t Au from 4m in hole SYRC0003.
  • The PDIP chargeability anomaly at Sheepyard is associated with elevated pyrite and alteration, which accompanies the gold mineralisation.
  • The mineralisation can be detected using geophysics, and there is potential for higher gold grades in parts of the mineralisation.
  • The Walkers Hill Project gold-in-soil trend stretches for over 4.0km to the north-west of the recent drilling, and several other mineralised trends have been identified within the Sheepyard gold-in-soil anomaly.
  • The results have provided a clearer vector for targeting higher-grade mineralisation associated with the PDIP conductor and major structural positions.
  • The Maroonbah Prospect to the north-west of Sheepyard appears to be the larger and stronger soil anomaly, and Talisman is looking forward to accessing this area for initial exploration work in the December quarter.

Statistics:

  • The RC drilling program consisted of five Reverse Circulation (RC) holes for 755m to test historical near-surface mineralisation and the PDIP chargeability feature. (Source: Talisman Mining news release)
