Talisman Mining (ASX:TLM) is filling the rest of its 2023 exploration calendar with diamond drilling, reverse circulation (RC) drilling, and survey work in New South Wales.
The company says a diamond rig will soon be mobilised to its Rip N Tear prospect — part of its wider Lachlan Copper-Gold Project — to begin drilling some diamond tails as it awaits further assays from recent RC work in the area.
Meanwhile, an RC rig will return to the prospect before the end of the month to in-fill between holes MYRC0002 and MYRC0003, test the extent of mineralisation to the west, and potentially drill at the southern moving-loop electromagnetic (MLEM) anomaly in the area.
Talisman plans to complete additional MLEM surveys and soil/auger geochemical surveys around the Rip N Tear area before the end of the year.
These plans come amid an expansion of the prospective horizon at Rip N Tear to more than one kilometre on the back of Talisman’s recent RC work.
The company reports that hole MYRC0003 struck 84m @ 1.5% lead, 15 grams per tonne (g/t) silver, and 0.1 % zinc along-strike from a recent hit of 192m @ 1.3% lead and 10g/t silver.
This RC hole was suspended at 268m in mineralisation.
Meanwhile, Talisman observed anomalous lead, zinc, and sulphide mineralisation via portable X-ray fluorescence work at four other holes in the prospect area, with assays pending for these holes.
Of the 7 holes drilled, 6 ended in mineralisation, short of Talisman’s MLEM target depth. As such, the planned diamond drilling is designed to complete core tails on some of these holes.
Talisman shares closed 7.14% higher at $0.15 on 6 November.
Talisman Managing Director Andrew Munckton says the latest assay results have demonstrated the ‘extensive’ nature of the mineralised system at Rip N Tear.
“Towards the bottom-of-hole in both MYRC0002 and MYRC0003, the mineralisation appears to be increasing in grade, with 20m of 2.7% Pb and 24.5g/t Ag intersected from 194m down-hole in MYRC0002 and 42m at 1.95% Pb, 17g/t Ag, 0.15% Zn and 0.10% Cu from 226m to end of hole in MYRC0003.
Importantly, the zones of lead, silver, zinc and copper mineralisation intersected at depth in both holes correspond closely to the extensive modelled MLEM targets and surface Pb-in-soil anomalies – confirming the conductor to be a mineralized base metal sulphide zone. The Northern MLEM target is extensive and spans over 3km in length.
“Importantly, the zones of lead, silver, zinc and copper mineralisation intersected at depth in both holes correspond closely to the extensive modelled MLEM targets and surface Pb-in-soil anomalies”
We believe that the RC drilling and the planned diamond tails will define the style, nature, and extent of the mineralisation at the two chargeable anomalies.”
Munckton says its targets in the prospect area remain open to the northeast, and further MLEM work is planned to test if the conductive features continue along the interpreted structure within the tenure.
Talisman Mining is a junior explorer focused on gold and base metals in New South Wales.
Alongside its Lachlan Project, the company also owns the Lucknow Gold Project, also in New South Wales.
