15 May 2023
High-Grade Gold With Significant Base Metals
Intersected at Durnings Prospect, NSW
High-grade assays of up to 17.5g/t Au, 1.4% Cu and 12.8g/t Ag reinforce the
polymetallic potential of the area and extend the known mineralisation at depth
Highlights:
•
High-grade gold and encouraging base metal assay results returned for drill-holes displaying
heavily disseminated and veined sulphides at the Durnings Prospect, within the Lachlan
Copper-Gold Project in NSW.
•
Best assays in drill-hole DRRC0001 were:
o
8m @ 6.3 g/t Au, 0.77% Cu, 0.27% Pb, 0.36% Zn & 6.3g/t Ag from 82m, including:
2m @ 17.5g/t Au, 1.4% Cu, 0.32% Pb, 0.36% Zn and 12.8g/t Ag from 88m.
•
Base and precious metal mineralisation was seen to the end-of-hole, suggesting that the
mineralisation continues at depth well below historic drilling.
•
Encouraging base and precious metal intersections were also seen in extensional holes drilled
as part of the program, including 8m @ 0.51g/t Au, 0.19% Pb, 0.5% Zn and 8.47g/t Ag in
DRRC0004 from 196m down-hole.
•
This suggests that the high-grade intercept forms part of a much larger mineralising system,
which may be geologically related to the nearby Kaolin Shaft prospect.
•
Encouragingly, assays have now confirmed previously reported visual sulphides, which are
strongly correlated to mineralised zones, with logged sulphide veins linked to gold and copper
mineralisation.
•
Work continues to plan follow-up drilling as a priority at the Durnings Prospect, focusing on
extensions of the high-grade copper-gold mineralisation intersection in DRRC0001.
Talisman Mining Ltd (ASX: TLM, Talisman) is pleased to advise that it has received highly
encouraging gold and base metal assay results from recent Reverse Circulation (RC) drilling at
the Durnings Prospect, which forms part of its extensive pipeline of exploration targets within its
100%-owned Lachlan Copper-Gold Project (Lachlan Project) in NSW (Appendix 1).

Durnings Prospect
A significant high-grade intersection of 8m @ 6.3g/t Au, 0.77% Cu, 0.27% Pb, 0.36% Zn and 6.3g/t
Ag from 82m down-hole in DRRC0001 has been returned from drilling at the Durnings Prospect,
with sulphide mineralisation returned through the entire hole to end-of-hole (Figure 1, Table1 and
Table2). This has extended the known sulphide mineralisation at the prospect significantly as well
as delivering outstanding gold mineralisation results, elevating this prospect area in Talisman’s
exploration targeting pipeline.
The polymetallic nature of the mineralisation intersected is particularly encouraging, as the
concurrent intersection of both the copper-gold and lead-zinc-silver mineral systems known to
mineralise the Cobar Basin in NSW suggests a long-lived structural control in this area acting as a
conduit for both phases of mineralising fluids.
Assays indicate that the extensive sulphidic zones first reported 1 as visual sulphides are strongly
correlated to mineralisation, with disseminated sulphides hosting lead-zinc mineralisation and a
phase of sulphide veining associated with copper and high-grade gold mineralisation. Sulfur assays
corresponded well to visual estimates of sulphides and largely fell within the estimated ranges first
reported.

All significant intercepts based on cut-off’s are provided in Table 2.
Historic drilling at the prospect by various explorers has not been systematic with a number of
shallow holes drilled at various orientations and assayed for limited element suites, making
interpretation difficult. Not all historical holes were assayed for Au. The average of 33 historic
drillholes in the main Durnings Prospect area is 78 metres, with limited holes drilled deeper than
150m. The intersection of high-grade gold associated with ore-grade copper indicates that the
Durnings Prospect remains highly prospective for further mineralisation at depth.
Figures 2, 3 and 4 demonstrate the high-grade intersection in DRRC0001 related to historic drilling
for gold, copper and zinc grades respectively. Drill samples are currently being scanned to acquire
hyperspectral alteration data and further technical work is being expedited on geochemical and
structural analysis to determine follow-up targets for additional drilling.

Kaolin Shaft Prospect
Two holes for a total of 444 metres of RC drilling (KSRC0013-KSRC0014) were completed on the
Kaolin Shaft prospect (Table 1, Figure 5), following up on 2022 drill programs 2. These were designed
to target structurally controlled mineralisation thought to be associated with a faulted NW-SE
anticline. Assay results have been returned for both drillholes with encouraging base and precious
mineralisation encountered in both holes.
KSRC0013 intersected a shallow zone of precious metal mineralisation returning 8m @ 0.75g/t Au
and 8.5g/t Ag from 52m, and a deeper zone of base metal mineralisation returning 8m @ 0.26% Zn
from 190m (Table 2, Figure 5).
KSRC0014 returned results indicating an intersection of remobilised zinc mineralisation associated
with the oxide-sulphide transitional zone (14m @ 0.31% Zn from 54 metres) and a deeper profile of
low-level zinc-lead mineralisation at end of hole (8m @ 0.13% Zn from 214 metres) (Table 1 and
Table 2).

Figure 5 - Kaolin Shaft Talisman and historic drilling.
The intersection of shallow gold mineralisation in drillhole KSRC0013 under transported cover and
distal from historic drilling suggests that the Kaolin Shaft Prospect has further mineral potential which
has not been tested by historic drilling.
Step-out drilling was successful in identifying further mineralisation and validating the structurally
controlled model. Further work will focus on understanding gold and zinc mineralisation at the
prospect, assessing further extensions of shallow gold mineralisation from KSRC0013, and further
investigating the Kaolin Shaft – Durnings Mineralised Trend. (Figure 6)

Management Comment
Talisman’s CEO, Shaun Vokes, said: “These initial results from Durnings are very encouraging, both
in terms of the high-grade gold intersection returned and the pervasive combinations of base and
precious metals returned in the step-out holes. In combination with the results from the Kaolin Shaft
drilling just to the north-west, these results highlight that this whole area is highly mineralized.
“We need to do more interpretative work to understand if there is a larger mineralising system at
play here and what the key to unlocking it is to generate an exciting new discovery.
“The team is already planning future work programs in this area as a priority while continuing to work
flat-out on the current drilling programs, testing multiple geophysics targets throughout our Central
Lachlan Project.”

About Talisman Mining
Talisman Mining Limited (ASX:TLM) is an Australian mineral development and exploration company. The Company’s aim is to
maximise shareholder value through exploration, discovery and development of complementary opportunities in base and
precious metals.
Talisman has secured tenements in the Cobar/Mineral Hill region in Central NSW through the grant of its own Exploration Licenses
and through a joint venture agreement. The Cobar/Mineral Hill region is a richly mineralised district that hosts several base and
precious metal mines including the CSA, Tritton, and Hera/ Nymagee mines. This region contains highly prospective geology that
has produced many long-life, high-grade mineral discoveries. Talisman has identified a number of areas within its Lachlan Cu-Au
Project tenements that show evidence of base and precious metals endowment which have had very little modern systematic
exploration completed to date. Talisman believes there is significant potential for the discovery of substantial base metals and
gold mineralisation within this land package and is undertaking active exploration to test a number of these targets.
Talisman also has a majority participating interest in a joint venture with privately-owned Lucknow Gold Limited in relation to the
Lucknow Gold Project (EL6455) in New South Wales. The Lucknow Goldfield was discovered in 1851 and was one of the earliest
goldfields to be mined commercially in Australia. Historic production records at the Project are incomplete, however in excess of
400,000 ounces of gold has reportedly been produced at grades of 100 to 200 g/t gold 3.Very little modern exploration has been
completed outside of the existing mine workings and Talisman intends to undertake a program of geochemical surface sampling
and mapping at the Project ahead of a drilling program to test for potential down plunge extensions of the high-grade gold ore
shoots and repeat structures throughout the Project area.

where ‘industry standard’ work has been done
this would be relatively simple (e.g. ‘reverse
circulation drilling was used to obtain 1 m
samples from which 3kg was pulverised to
produce a 30 g charge for fire assay’). In other
cases, more explanation may be required, such
as where there is coarse gold that has inherent
sampling problems. Unusual commodities or
mineralisation types (e.g. submarine nodules)
may warrant disclosure of detailed information.

oriented and if so, by what method, etc).
Commentary
•
RC samples are collected at two metre intervals via a drill
rig mounted cyclone and static cone splitter set to a 12%
split to produce a nominal 4-7kg sample which was
collected in a pre-numbered sample bag.
•
Sampling is controlled by Talisman protocols and QAQC
procedures as per industry standard and a chain of custody
maintained through transfer to ALS Laboratories in Orange,
NSW
•
RC samples were dried, crushed (where required), split
and pulverised (total prep) to produce a master pulp. From
this master pulp, a 0.25g sub sample was taken for multielement analysis by four acid digest with an ICP-MS finish.
A 30g sub sample was also taken for fire assay with ICPAES finish.
•
RC drilling cited in this report was undertaken by
Resolution Drilling Pty Ltd using a UDR650 multipurpose
track base-mounted drill rig operating in a Reverse
Circulation configuration. A truck-mounted booster and
compressor provided high pressure air with an auxiliary
compressor used where ground conditions warranted.
RC drilling was completed with a face sampling hammer of
nominal 150mm size.

RC logging records lithology, mineralogy, mineralisation,
alteration, structure, weathering, colour and other primary
features of the rock samples and is considered to be
representative across the intercepted geological units.
RC logging is both qualitative and quantitative depending
on the field being logged.
All RC drill-holes are logged in full to end of hole.
RC samples were dried, crushed (where required), split
and pulverised (total prep) to produce an 0.25g sub sample
for base metal analysis or a 30g sub sample for gold
analysis by fire assay
QAQC protocols for all RC sampling involved the use of
Certified Reference Material (CRM) as assay standards.
All QAQC controls and measures were routinely reviewed.
Sample size is considered appropriate for geochemical
sampling for base-metal and gold mineralisation given the
nature of drilling and anticipated distribution of
mineralisation.
Field duplicates were collected at a 1 in 30 sample rate.
QAQC protocols for all RC sampling involved the use of
certified reference materials as assay standards, inserted
at a 1 in 50 sampling rate.
Blank samples were inserted at a 1 in 50 sampling rate
using a certified reference material coarse blank.
All assays are required to conform to the procedural QAQC
guidelines as well as routine laboratory QAQC guidelines.
All QAQC controls and measures were routinely reviewed.
Laboratory checks (repeats) occurred at a frequency of 1 in
25.
Significant intercepts have been verified by alternate
company personnel.
Logging and sampling data is captured and imported using
Ocris software.
