Lead-Zinc-Silver Intercepts in RC drilling above
Southern EM Conductor at Rip n Tear
Deeper diamond drilling now in progress to test underlying MLEM conductors
Highlights:
•
Further assay results have been received from recent Reverse Circulation (RC) drilling designed
to test Moving Loop Electromagnetics (MLEM) conductors at the Rip N Tear Prospect, part of
the Lachlan Project in NSW.
•
Assays have been returned for holes MYRC0004 to MYRC0007, which intersected several
zones of disseminated galena (lead) (Pb), silver (Ag), sphalerite (zinc) (Zn) and pyrite:
o
MYRC0004 – 18m at 0.28% Pb, 5.2g/t Ag and 0.01% Zn from 142m to 160m;
o
MYRC0005 – 6m at 0.81% Pb and 5.6g/t Ag from 44m to 50m;
o
MYRC0006 – 10m at 0.85% Pb, 3.3g/t Ag and 0.02% Zn from 246m to 256m; and
o
MYRC0007 – 10m at 0.81% Pb, 12.35g/t Ag and 0.04% Zn from 222m to 232m.
•
These narrower and lower-grade zones of lead, silver and zinc mineralisation have been
intersected in the weathered rock zone above the 2.0km-long Southern MLEM Conductor.
•
All RC holes at this southern target have not penetrated the MLEM conductor and were
suspended due to difficult RC drilling conditions. The holes will be extended with diamond drill
hole tails to test the deeper, conductive target.
•
The diamond drill rig has completed the first extensional hole at the Northern MLEM Conductor,
extending the suspended RC hole MYRC0003 from 268m to 411m down-hole. Results for the
extension of this hole will be reported as they come to hand.
•
A further three RC holes are planned to be completed at the Northern Conductor during
December to confirm the continuity of mineralisation between the wide intercepts reported in
MYRC0002 and MYRC0003 and to test for extensions of the mineralisation underneath the
MLEM anomaly a further 1,000m to the west of MYRC0002.
•
Diamond drilling is currently in progress to test beneath the Southern Conductor, to extend RC
hole MYRC0004.
•
An expanded ground-based MLEM survey has commenced to extend coverage of the
prospective chargeable Northern MLEM conductor target to the east.

Further to its announcements of 20 October and 6 November 2023, Talisman Mining Limited (ASX:
TLM, Talisman) is pleased to advise that it has received assays from a further four Reverse
Circulation (RC) holes targeting the Southern MLEM Conductor at the Rip N Tear Prospect, part of
its 100%-owned Lachlan Project.
Rip N Tear is the first area to be tested as part of a 7,200m RC drilling campaign currently underway
at four priority prospects within the Lachlan Project area (see Figure 1).
Assays have now been received for the next four RC holes drilled at Rip N Tear, where a maiden
1,650m broad-spaced 7 RC hole drilling program commenced in early September.

The Rip N Tear Prospect is an under-explored target defined by strongly anomalous base metal soil
geochemistry containing two large, coherent conductive MLEM anomalies. (ASX announcement 8 May 2023).
The prospect is situated within a complex structural setting associated with NNE and NE trending
faults, which are interpreted to provide a pathway for mineralised fluids from local granite intrusions.
Historical drilling was limited to three percussion holes (~61m deep, drilled in 1970’s). The current
program consists of seven RC holes designed to test the two, north and south conductive anomalies
at depth at approximately 800m to 1,000m drill-hole spacing.
Results

268m at End-of-Hole (EOH), including:
§
42m at 1.95% Pb, 16.7g/t Ag, 0.19% Zn and 0.01% Cu from 226m to 268m,
including:
§
6m at 2.56% Pb, 14.6g/t Ag and 0.70% Zn from 262m to 268m EOH.
•
Both MYRC0002 and MYRC0003, which are located approximately 1,000m apart, were
suspended in mineralisation due to difficult RC drilling conditions. Diamond tails are planned
for these two RC holes to fully test the targeted MLEM conductor. The first diamond tail at
MYRC0003 has been completed from 268m to 411m.
•
MYRC0002 RC results were first reported in late October (see ASX announcement 20
October). MYRC0003 RC results were reported 6 November (see ASX announcement 6
November).

Geology and Mineralisation
The Rip N Tear Prospect is located within EL8615 on the eastern edge of the Canbelego - Mineral
Hill Rift Zone (Figure 1), adjacent to a large, controlling, basin margin, NW-SE oriented structure.
Devonian-age sediments of the Ewolong Formation (sandstone and conglomerate) and Gwando
Siltstone host the prospect. To the west lies the older Ordovician-age Girilambone Group, which is
intruded by the early Devonian-age Yellow Mountain Granite.
The granite intrusion(s) are interpreted to be the source of heat, fluid and metal for several other
lead-silver-zinc and copper-gold deposits and mineralised prospects along the Mineral Hill Rift.
Rip N Tear is cut by two NW-SE trending faults interpreted to be transverse faults in a rift setting.
Anomalous lead-in-soil geochemistry results and the coincident MLEM response in Figure 2 and
Figure 3 highlight the proximity of the faults to the surface expression of the mineralisation.
Broad zones of disseminated sulphides in fresh rock are associated with sericite alteration in
sandstone, siltstone and coarse angular quartz breccia/conglomerate.
4
At the Southern MLEM anomaly, the majority of the anomalous low-grade lead-silver intersections
occurred in weathered rock above the MLEM target position (see comments section in Table 2
Significant Intersections for details).

Next Steps
The diamond drill rig has completed the extension of MYRC0003 from 268m to 411m down-hole.
Results for the extension of this hole will be reported as they come to hand.
Diamond drilling has commenced on the extension of MYRC0004 from 234m.
The RC rig will return to Rip N Tear imminently to complete further RC drilling (see Figure 2 for
planned RC drill hole locations). These holes will target:
•
In-fill at approximately 500m hole spacing between MYRC0002 and MYRC0003 to
confirm the continuity of the mineralisation beneath the Northern MLEM anomaly.
•
Test the extent of the mineralisation approximately 1,000m west of MYRC0002 at
500m spacing beneath the Northern MLEM anomaly.
•
Potential additional RC drilling at the Southern MLEM anomaly is subject to diamond
drilling progress and interpretation of results.
5
Additional ground-based MLEM surveys have commenced to investigate if other large targets exist
along the structural corridor north-east of the current drilling.
Management Comment
Talisman’s Managing Director, Andrew Munckton, said: “As expected, assay results from holes
MYRC0004 to MYRC0007 returned relatively narrow (generally 6m to 18m) intersections of lowgrade lead-silver and zinc mineralisation. All these RC holes were suspended above the targeted
Southern MLEM anomaly, with the lower-grade intersections in MYRC0001 and MYRC0004 to
MYRC0007 occurring in weathered sandstone units. We will be extending all these RC holes with
diamond tails in the coming weeks to test the targeted deeper source of the conductivity anomaly
with diamond core.
“At the Northern MLEM anomaly, the zones containing disseminated galena, silver, sphalerite, minor
chalcopyrite and pyrite with strong sericite alteration were hosted in fresh sandstone and siltstone.
These zones are being further tested and extended with diamond core. Towards the bottom-of-hole
in both MYRC0002 and MYRC0003, the mineralisation appears to be increasing in grade, with 20m
at 2.7% Pb and 25.4g/t Ag intersected from 194m down-hole in MYRC0002 and 42m at 1.95% Pb,
16.7g/t Ag, 0.19% Zn and 0.08% Cu from 226m to end-of-hole in MYRC0003.
“Importantly, the zones of lead, silver, zinc and copper mineralisation intersected at depth in both
these holes were recorded in fresh rock. The fresh rock intersections also sit above the modelled
Northern MLEM target. The diamond tails program is designed to confirm the source of the conductor
below this mineralised base metal sulphide zone. The Northern MLEM target is extensive and spans
over 3km in length.
“We believe that the current diamond tails and proposed follow-up RC drilling will define the style,
nature and extent of the mineralisation at the two chargeable anomalies. The targets remain open
to the north-east and further ground-based MLEM surveys are underway to test if the conductive
features continue along the interpreted structure.
“Our geologists are looking forward to integrating the knowledge derived from the recently
commenced diamond tails program to gain a more accurate picture of the orientation and style of
lead-silver-zinc-copper sulphide mineralisation and to test this extensive structural corridor and
emerging mineralised system.”

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 several 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 secured access to over 1000 km2 of highly prospective tenure in South Australia’s Gawler Craton known as
the Mabel Creek Project. Mabel Creek is prospective for large scale Iron Oxide Copper Gold (IOCG) deposits and intrusion related
rare earths and battery metals mineralisation. Mable Creek is surrounded by similar tenure owned and being actively explored by
Australia’s biggest resource companies including BHP, Rio Tinto and FMG.

JORC Code explanation
•
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 undergo routine 2 metre composite pXRF
analysis using a Olympus Vanta M-series to aid in logging
and identifying zones of interest.
•
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 for gold
with ICP-AES finish.
Drill type (e.g. core, reverse circulation, openhole hammer, rotary air blast, auger, Bangka,
sonic, etc) and details (e.g. core diameter,
triple or standard tube, depth of diamond tails,
face-sampling bit or other type, whether core is
oriented and if so, by what method, etc).
•
RC drilling cited in this report was undertaken by Strike
Drilling Pty Ltd using a LC36 (KWL 700) truck-mounted
Reverse Circulation drill rig. A truck-mounted booster and
compressor provided high pressure air with an auxiliary

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 a 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.
Field duplicates returned a reasonable level of precision
with some minor variation in Au attributed to nugget effect
of gold mineralisation.
Each 2m composite RC sample undergoes routine pXRF
analysis using a Olympus Vanta M-series to aid in logging

Whether sample compositing has been
applied.
•
Whether the orientation of sampling achieves
unbiased sampling of possible structures and
the extent to which this is known, considering
the deposit type.
•
If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to have
introduced a sampling bias, this should be
assessed and reported if material.

The measures taken to ensure sample
security.
•
OREAS supplied standard reference materials were used
to calibrate the pXRF instrument every 30 samples.
•
Significant intercepts have been verified by alternate
company personnel.
Logging and sampling data is captured and imported using
Ocris software.
Assay data is uploaded to a secure database directly from
the CSV file provided by the laboratory.
Primary laboratory assay data is always kept and is not
replaced by any adjusted or interpreted data
