Monty Exploration Update
Massive sulphides intersected up-dip in Lower Zone
High-grade copper assay results from RC drilling in Upper Zone
Talisman Mining Limited (ASX: TLM 'Talisman') is pleased to announce that Sandfire Resources NL (ASX: SFR; 'Sandfire') has provided an update on ongoing activities at the Monty copper-gold discovery within Talisman's Springfield Project located approximately 10km east of the DeGrussa Copper- Gold Mine (see Appendix 1).
Monty is the first significant VMS copper-gold discovery in the Doolgunna region outside of DeGrussa and Sandfire is continuing drilling to define the extents of mineralisation at Monty itself and to target other prospective areas; both in the immediate vicinity and further afield.
The collar locations of holes drilled to date by Sandfire are shown in the plan view diagram below (see Figure 1) and Table 1.

Massive sulphides intersected up-dip in Lower Zone
Diamond drill hole TLDD0021 was drilled approximately 64 metres up-dip of TLDD0009 (7.9m @ 8.3% Cu and 2.4 g/t Au from 363.1m down hole and 4.8m @ 4.9% Cu and 1.1 g/t Au from 385.8m down hole) (see TLM ASX announcement - 8 September 2015) and approximately 104 metres down-dip of TLDD0016, which did not intersect massive sulphides (see TLM ASX announcement - 14 September 2015).
Sandfire have advised that TLDD0021 intersected four zones of massive sulphides within the host sequence of the Lower Zone:
-
0.6 metres of massive sulphides from 239.8m to 240.4m down-hole
(true width not known at this time, top of intercept is approximately 211m vertically below surface);
-
1.4 metres of massive sulphides from 241.0m to 242.4m down-hole
(true width not known at this time, top of intercept is approximately 212m vertically below surface);
-
7.3 metres of massive sulphides from 286.2m to 293.5m down-hole
(true width not known at this time, top of intercept is approximately 250m vertically below surface); and
-
1.2 metres of massive sulphides from 299.8m to 301.0m down-hole
(true width not known at this time, top of intercept is approximately 263m vertically below surface).
Assay Results - TLRC0008
Sandfire have also advised that it has received assay results from the relatively shallow Reverse Circulation (RC) drill hole TLRC0008 (refer Figure 1 and Table 1) located south west 40 metres along strike from the initial Upper Zone discovery hole TLRC0004 (18m grading 5.7% Cu and 2.4g/t Au from 107.0m) (see TLM ASX announcement - 13 August 2015). These assay results are:
-
6.0 metres grading 7.8% Cu and 0.9g/t Au from 89m to 95m down-hole
(true width not known at this time but likely to be considerably thinner than down-hole width, top of intercept is approximately 90m vertically below surface); and
-
11.0 metres grading 15.0% Cu and 1.9g/t Au from 112m to 123m down-hole
(true width not known at this time but likely to be considerably thinner than down-hole width, top of intercept is approximately 100m vertically below surface).
Sandfire have advised that the upper intersection of TLRC0008 (6.0 metres at 7.8% Cu and 0.9g/t Au) visually exhibited weak oxidation of the massive sulphides. Sandfire have also advised that they therefore believe that it is possible that the grades in this upper intersection may have been elevated by supergene processes.
Geological Discussion / Interpretation
Ongoing work at Monty has provided sufficient detail to enable Sandfire to provide an updated interpretation of the geological setting of the known mineralisation at Monty. An updated vertical longitudinal projection (looking to the south-east) is shown in Figure 2 below. Specific interpretation of the upper and lower mineralised zones at Monty is discussed below.
Figure 2 - Vertical longitudinal projection of Monty showing drill-hole piercepoints at the top of the primary intercept shown in bold. All intercepts are down-hole widths.
Initial interpretation of the Lower Zone
The Lower Zone at Monty incorporates the massive sulphide mineralisation intersected in TLDD0004A, TLDD0005, TLDD0009, TLDD0010 (previously reported) and TLDD0021 (reported above, assays pending).
The mineralisation seen in the drilling so far, can be interpreted as a dominant primary lens (as seen in holes TLDD0004A and TLDD0005), with possibly stacked subordinate lenses, above and below the primary lens, in certain areas (as seen in holes TLDD009, TLDD0010 and TLDD0021). This is illustrated in the interpretive cross-section for the Lower Zone as shown in Figure 3 on the following page.
Other minor intersections of massive sulphides in surrounding holes, and the top of alteration and disseminated sulphides in the periphery of the mineralisation, have informed this interpretation by Sandfire. The primary zone of mineralisation strikes approximately 220° and ranges in dip from 65°- 85° to the north-west.
Figure 3 - Interpretive cross-section of the Monty mineralisation (Lower Zone)
Initial interpretation of the Upper Zone
The mineralisation in the Upper Zone, and its host stratigraphy, is currently defined by RC holes TLRC0004, TLRC0008 and TLRC0009 (as previously reported, see Figure 1 and Figure 2 on preceding pages). Sandfire interpret the geometry of the Upper Zone to be steep to sub-vertical in dip.
As a result, Sandfire interpret that the RC holes in the Upper Zone are likely to have intersected the mineralisation at a low angle, with the reported down-hole intersections potentially being considerably thicker than the anticipated true width. The grades reported in this Upper Zone may also therefore not be fully representative and further drilling is required to confirm the interpretation and determine the optimum angle for drilling to further define the mineralisation.
All current drill holes in the Upper Zone at Monty are drilled towards the south-east. In order to confirm and refine the above geological interpretation additional holes are planned by Sandfire to be drilled towards the north-west. Sandfire advise that these holes will be drilled both up-dip and down-dip of the existing intercepts in holes TLRC0004, TLRC0008, and TLRC0009.
Other Exploration
Sandfire have also advised Talisman of the results from two other drill holes; TLRC0012 and TLDD0022.
TLRC0012 was drilled to the south-east (approximately 110 metres up-dip) of TLRC0009, after penetrating the transported cover, intersected a 13 metre interval of sediment before entering dolerite. This sediment is interpreted by Sandfire to be the lower part of the host horizon (below the level of mineralisation in the Upper Zone) and is considered to be consistent with the geological interpretation that the mineralisation in the Upper Zone, and its host stratigraphy, has a steep to sub-vertical dip.
TLDD0022 was drilled approximately 130 metres down-dip of TLRC0008 and was designed to define the margin of the mineralisation in this area. The hole intersected the host horizon sediments, with weak chloritic alteration, without intersecting any massive sulphide mineralisation.
Further Exploration Activity
Sandfire are continuing drilling at Monty with further Diamond holes underway and planned to test the interpreted extents of the mineralisation in the Lower Zone, as well as to confirm the dip of the mineralisation in the Upper Zone.
In addition to continuing definition drilling around the currently known mineralisation, Sandfire are also working towards generating potential exploration targets along the highly prospective 5km Monty corridor as part of the search for additional lenses of mineralisation at Monty.
Further afield within the Springfield Project, Sandfire consider the Homer Prospect to be a high priority exploration target area which lies within the immediate eastern extension of the DeGrussa Mine Corridor. Additional drilling at Homer is planned by Sandfire
The Springfield Project is subject to an exploration farm-in joint venture between Sandfire and Talisman where Sandfire has the right to earn up to a 70% interest in Talisman's Doolgunna Projects by the expenditure of $15 million on exploration at the Projects.

Commentary
|
Sampling techniques
|
-
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down-hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.
-
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
-
Aspects of the determination of mineralisation that are Material to the Public Report.
-
In cases 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 3 kg 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.
|
-
The sampling method employed by Sandfire i s h a l f -core sampling of NQ2 core from Diamond drilling (DD)
-
Sandfire collect RC samples by cone splitter for single metre samples or a sampling spear for first pass composite samples using a face sampling hammer with a nominal hole diameter of 140mm
-
Sampling is guided by Sandfire protocols as per industry standard.
-
Diamond drill core sample size reduction is through a Jaques jaw crusher to -10mm and a second stage reduction via Boyd crusher to - 4mm.Representitive sub samples are split and pulverised via an LM5 mill.
-
RC samples are crushed to -4mm through a Boyd crusher and representative sub samples are split and pulverised with an LM5 mill.
-
Pulverising is to nominal 90% passing -75µm and is checked using wet sieving technique.
-
Samples are assayed using Mixed 4 Acid Digest (MAD) 0.3g charge and MAD Hotbox 0.15g charge methods with ICPOES or ICPMS.
-
Fire Assay is completed by firing 40g portion of the sample with ICPMS finish.
|
Drilling techniques
|
-
Drill type (e.g. core, reverse circulation, open-hole 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).
|
-
Sandfire Diamond drilling is completed using NQ2 size coring equipment.
-
RC drilling is with a face sampling hammer of a nominal 140mm hole diameter.
-
All drill collars are surveyed using RTK GPS.
-
All core, where possible is oriented using a Reflex ACT II RD orientation tool.
-
Downhole surveying is undertaken using a gyroscopic survey instrument.
|
Drill sample recovery
|
-
Method of recording and assessing core and chip sample recoveries and results assessed.
-
Measures taken to maximise sample recovery and ensure representative nature of the samples.
-
Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.
|
-
Sandfire Diamond core recovery is logged and captured into the database. Core recoveries are measured by drillers for every drill run. The core length recovered is physically measured for each run and recorded and used to calculate the core recovery as a percentage of core recovered.
-
Appropriate measures are taken to maximise sample recovery and ensure the representative nature of the samples. This includes Diamond core being reconstructed into continuous intervals on angle iron racks for orientation, metre marking and reconciled against core block markers.
-
RC sample recovery is good with almost no wet sampling in the project area
-
Samples are routinely weighed and the information captured into the central secured database.
-
No sample recovery issues have impacted on potential sample bias
|
Logging
|
-
Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
-
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.
-
The total length and percentage of the relevant intersections logged.
|
-
Sandfire Geological logging is completed for all holes and is representative across the orebody. The lithology, alteration and structural characteristics of core are logged directly to a digital format following procedures, and using Sandfire NL geologic codes. Data is imported into Sandfire NL's central database after validation in LogChief™.
-
Logging is both qualitative and quantitative depending on field being logged.
-
All cores are photographed.
-
All drill holes are fully logged.
|
Sub- sampling techniques and sample preparation
|
-
If core, whether cut or sawn and whether quarter, half or all core taken.
-
If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.
-
For all sample types, the nature, quality and appropriateness of the sample preparation technique.
-
Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
-
Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.
-
Whether sample sizes are appropriate to the grain size of the material being sampled.
|
-
Sandfire complete Diamond core orientation where possible and all core is marked prior to sampling. Half core samples are produced using an Almonte Core Saw. Samples are weighed and recorded.
-
RC samples are split using a cone or riffle splitter. The majority of samples collected are dry. On occasion that wet samples are encountered they are dried prior to splitting with a riffle splitter.
-
All samples are sorted, dried at 80° for up to 24 hours and weighed. Samples are then crushed through a Jaques crusher to nominal -10mm. A second stage crushing is through a Boyd crusher to nominal -4mm.
-
Sample splits are weighed at a frequency of 1:20 and entered into the job results file. Pulverising is completed using LM5 mill to 90% passing 75%µm using wet sieving technique.
-
1:20 grind quality checks are completed for 90% passing 75%µm criteria to ensure representativeness of sub-samples.
|
Sub- sampling techniques and sample preparation (Continued)
|
-
Sampling is carried out in accordance with Sandfire protocols as per industry best practice.
-
No field duplicates have been taken.
-
The sample sizes are considered appropriate for VHMS and Gold mineralisation types.

The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
-
For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.
-
Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.

Samples are assayed using Mixed 4 Acid Digest (MAD) 0.3g charge and MAD Hotbox 0.15g charge methods with ICPOES or ICPMS. The samples are digested and refluxed with a mixture of acids including Hydrofluoric, Nitric, Hydrochloric and Perchloric acids and analysis conducted for multi elements including Cu, Pb, Zn, Ag, As, Fe, S, Sb, Bi, Mo, Re, Mn, Co, Cd, Cr, Ni, Se, Te, Ti, Zr, V, Sn, W and Ba. The MAD Hotbox method is an extended digest method that approaches a total digest for many elements however some refractory minerals are not completely attacked. The elements S, Cu, Zn, Co, Fe, Ca, Mg, Mn, Ni, Cr, Ti, K, Na, V are determined by ICPOES, and Ag, Pb, As, Sb, Bi, Cd, Se, Te, Mo, Re, Zr, Ba, Sn, W are determined by ICPMS. Samples are analysed for Au, Pd and Pt by firing a 40g of sample with ICP AES/MS finish. Lower sample weights are employed where samples have very high S contents. This is a classical FA process and results in total separation of Au, Pt and Pd in the samples.
-
The analytical methods are considered appropriate for this mineralisation styles.
-
No geophysical tools are used in the analysis.
-
Sandfire DeGrussa QAQC protocol is considered industry standard with standard reference material (SRM) submitted on regular basis with routine samples. SRMs and blanks are inserted at a minimum of 5% frequency rate.

Verification of sampling and assaying
|
-
The verification of significant intersections by either independent or alternative company personnel.
-
The use of twinned holes.
-
Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
-
Discuss any adjustment to assay data.
|
-
Significant intersections have been verified by alternate Sandfire personnel.
-
None of the drillholes in this report are twinned.
-
Primary data is captured on field Toughbook laptops using Logchief™ Software. The software has validation routines and data is then imported into a secure central database.
-
The primary data is always kept and is never replaced by adjusted or interpreted data.
|
Location of data points
|
-
Accuracy and quality of surveys used to locate drill holes (collar and down- hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.
-
Specification of the grid system used.
-
Quality and adequacy of topographic control.
|
-
The Sandfire Survey team undertakes survey works under the guidelines of best industry practice.
-
All drill collars are accurately surveyed using RTK GPS system within +/-50mm of accuracy (X, Y, Z).
-
Downhole surveys are completed by gyroscopic downhole methods at regular intervals.
-
Coordinate and azimuth are reported in MGA 94 Zone 50.
-
Topographic control was established from LiDar laser imagery technology
|
Data spacing and distribution
|
-
Data spacing for reporting of Exploration Results.
-
Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.
-
Whether sample compositing has been applied.
|
-
Drill spacing is currently defined by geological criteria and is regarded as appropriate to determine the extents of mineralisation. This spacing is nominally 80m x 80m. Spacing is shown by the accompanying tables and figures.
-
Exploration drilling at Monty is preliminary and spacing and distribution of exploration results is not sufficient to support Mineral Resources or Ore Reserves.
-
No sample compositing has been applied to these exploration results.
|
Orientation of data in relation to geological structure
|
-
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.
|
-
No significant orientation based sampling bias is known at this time.
-
The drill holes may not necessarily be perpendicular to the orientation of the intersected mineralisation. All reported intervals are downhole intervals, not true widths. This will be established with additional drilling.
