Overview
The 100% owned Sinclair Nickel Project is located in the world-class Agnew-Wiluna Greenstone Belt in WA’s North-eastern Goldfields (Appendix 1). The Sinclair nickel deposit, developed and commissioned in 2008 and operated successfully before being placed on care and maintenance in August 2013, produced approximately 38,500 tonnes of nickel at an average life-of-mine head grade of 2.44% Ni. Sinclair has extensive infrastructure and includes a substantial 290km[2] tenement package covering more than 80km strike of prospective ultramafic contact within a 35km radius of the existing processing plant and infrastructure.
Talisman Mining Limited (ASX: TLM , “ Talisman ” or the “ Company ”) is pleased to advise that additional results from the recent exploration program of diamond and RC drilling at the 100%-owned Sinclair Nickel Project have now been received. These latest results, when combined with zones of massive sulphide mineralisation from shallow RC drilling undertaken at Delphi North in September 2016, including 9m @ 4.2% Ni from 131m downhole in SNRC019 (refer ASX Announcement – 7 October 2016), provide further evidence of the considerable prospectivity of the Sinclair ultramafic belt to host additional massive sulphide nickel deposits.
In addition to recent drill results at the Delphi and Delphi North Prospects, RC drilling from the recently completed program at the Schmitz Well South Prospect ( Figure 3 ) also confirmed the presence of wide zones of prospective, fertile high-MgO ultramafic rocks.
Talisman is highly encouraged by these recent results and will continue with a cost efficient, staged and focused exploration program at Sinclair during the forthcoming quarter at high priority targets in the near mine Sinclair Trend including further drilling at the Delphi North Prospect.
Delphi North
Delphi North is a high priority target corridor ( Figure 1 ) displaying a strong correlation with the Sinclair mine geological environment. It has confirmed historic nickel sulphide mineralisation over a strike length of 700m and is interpreted to represent a fertile mineralised setting with potential to host significant mineralisation.
As previously reported (refer ASX announcement – 07 October 2016 ) two fences of RC drill holes at Delphi North were drilled to test a shallower area up dip of previously reported massive sulphide mineralisation intersected in hole DED009 ( Figure 1 ). Results from this drilling confirmed near surface high-tenor nickel sulphide mineralisation in multiple zones of massive and stringer nickel sulphide mineralisation with significant intersections[1] including:
-
SNRC010: 4m @ 4.79% Ni from 154m down-hole;
-
SNRC012: 5m @ 2.39% Ni from 73m down-hole, and
-
SNRC019: 9m @ 4.20% Ni from 131m down-hole.
A complete list of all drilling results is provided in Table 2.
Following these successful initial RC drill results the Company extended the planned drill program at Delphi North to include an additional diamond drill hole (SND009) beneath hole SNRC019.
SND009 intersected 1.4 metres of massive nickel sulphides visually similar to those reported from the nearby RC holes in an interpreted basal position approximately 33 metres vertically below the massive sulphides from hole SNRC019. In addition to the massive sulphide intersection the hole also intersected a broad zone (~30 metres) of high-MgO ultramafic rocks containing stringer, disseminated and minor matrix-

style nickel sulphide mineralisation containing visual pyrrhotite and pentlandite nickel bearing sulphide minerals. Assay results are pending.
DHEM in SND009 delivered a number of modelled conductors that align closely with the massive sulphide intersections from recent RC and diamond drilling at Delphi North. A moderate conductance plate (3000 siemens) measuring approximately 140m x 50m intersects the recent sulphide intersections extending both to the north and south from existing drilling. A high conductance modelled anomaly of 15,000 siemens centred above and to the south of SND009 is interpreted to represent the thickest part of the massive nickel sulphides intersected to date. Talisman considers that these modelled conductors highlight the potential for Delphi North to host significant sulphide mineralisation.
Talisman is highly encouraged by the identification of this mineralised host ultramafic unit in close proximity to the previously intersected massive sulphides.

SND006 was drilled to test a conductor identified in the previously completed DHEM survey of SND001, some 50 metres to the south of SND001 ( Figure 1 ). The hole was interpreted by Talisman to intersect the target toward the top of the modelled EM plate and as such has not fully tested the targeted plate. Multiple zones of brecciated to massive sulphides (pyrrhotite, chalcopyrite & minor pentlandite) were intersected in SND006 including 3.5m @ 1.01% Ni from 403.2m down-hole.
Multiple ultramafic and sedimentary lithologies were intersected below the basal contact position and the geology is interpreted to be tightly folded hanging wall stratigraphy within a synclinal structure. It is also interpreted that the basal contact has been folded in a similar manner below the hole in a structural position similar to the Sinclair Mine geology. The brecciated to massive nature of the sulphide intersection in SND006 is consistent with Talisman’s geological interpretation of this position and validates the current exploration strategy to target massive sulphide mineralisation at Delphi North.
The nickel sulphide intersections logged in SND006 are encouraging and further work to confirm Talisman’s interpretation of the stratigraphy and mineralised environment is underway.
A DHEM survey has recently been completed in hole SND006. The survey identified multiple conductors, confirming the presence of nickel sulphide mineralisation in the vicinity of holes SND006 and SND001. The data has been processed and interpreted resulting in modelled plates with dimensions of 250m x 80m located in close proximity to SND006 and extending both north and south at a shallow plunge ( Figure 1 ).
Drill results confirm that the Delphi North prospect remains one of the highest priority target areas and further drilling is set to commence in November 2016.
Delphi
The Company recently completed two diamond drill tails (SND007 and SND008) on historic RC holes SNRC002 and SNRC004 to target untested, previously identified, stratigraphic and Moving Loop Electromagnetic (MLEM) conductors at Delphi ( Figure 2 ). These holes are offset from the main ultramafic trend.
SND007 intersected a wide zone of ultramafic rocks with minor matrix and stringer nickel sulphides . Below the ultramafic unit, the drill hole encountered pyrite-rich sediments which may explain the existing MLEM anomaly. Assay results are currently pending, however the presence of matrix and stringer nickel sulphides within ultramafic rocks in SND007 represents the identification of a new and previously untested, potentially fertile ultramafic unit.
A DHEM survey was recently completed at SND007. The survey was unable to reach the end of hole due to poor ground conditions however the survey identified a growing EM anomaly towards the end of the surveyed interval proximal to the matrix and stringer nickel sulphides and deeper pyrite rich sediments previously logged. Additional geological and geophysical interpretation will be undertaken to accurately define this EM anomaly.
Talisman will continue detailed interpretation of this area.
SND008 intersected a prospective high-MgO ultramafic unit, however no discernible sulphide mineralisation was logged in the drill core to explain the existing MLEM anomaly. A DHEM survey recently completed at SND008 did not return any significant EM anomalism and the original surface EM anomaly remains unexplained. Assays are pending.

Schmitz Well South
A fence of RC drill holes at Schmitz Well South to test an interpreted extension of the ultramafic unit under cover has recently been completed ( Figure 3 ). Talisman secured a grant from the Western Australian Department of Mines of up to $55,000 ($110,000 total drill cost split 50/50) for the co-funding of this exploration drilling.
Drilling intersected broad zones of prospective high-MgO ultramafic rocks, containing multiple zones of trace to disseminated (cloud) sulphides throughout. Assay results returned anomalous nickel grades with the highest grade being 1m @ 0.97% Ni from 193m down-hole in SNRC015.
The confirmation of the presence of fertile, high-MgO ultramafic units at Schmitz Well South is highly encouraging and validates Talisman’s original interpretation that Schmitz Well South represents a continuation of the fertile Schmitz Well and Sinclair ultramafic trend. Detailed interpretation of the results from this drilling will continue to inform Talisman’s interpretation and guide further exploration activities in the area.

Additional planned activity
As part of Talisman’s cost effective and focused exploration strategy at Sinclair a follow-up program of diamond drilling is scheduled at Delphi North and Stirling, as well as RC drilling at Sinclair East, Sinclair North and Parnassus. Drilling will commence in early November 2016 as part of the second phase of drilling over the wider Sinclair Trend.
Delphi North
A series of diamond drill holes are planned along strike and down plunge from recent shallow massive sulphide intersections at Delphi North ( Figure 4 ). It is interpreted that the massive sulphide mineralisation has a shallow plunge to the north similar to the Sinclair, Stirling and Skye nickel sulphides bodies.

Stirling
Stirling represents a mineralised ultramafic environment parallel and approximately 600 metres to the south of Sinclair that has delivered historic intersections of massive and disseminated-style nickel sulphides.
As part of ongoing project assessment and exploration targeting reviews, Talisman has recently completed reinterpretation of historic DHEM and lithologies highlighting the potential for Stirling to host significant thicknesses of massive and disseminated nickel sulphide mineralisation located within a fold hinge structure.
Talisman will complete one diamond drill hole ( Figure 5 ) targeting the interpreted mineralised position as a basis for ongoing work in the future.

Sinclair East
Sinclair East represents a fertile ultramafic unit immediately to the east of Sinclair and existing mine infrastructure. Historic drilling at depth has returned 2.16m @ 2.12% Ni (CWD536B) however the mineralised position remains effectively untested, especially in the shallow environment.
Talisman has completed interpretations projecting this ultramafic position close to surface ( Figure 6 ) and will complete a traverse of RC holes ( Figure 5 ) to test for nickel sulphide mineralisation and the potential of this fertile ultramafic contact position to extend close to surface.
==> picture [468 x 156] intentionally omitted <==
Figure 6: Interpretation of the Sinclair East ultramafic unit projected close to surface.
Sinclair North
Very limited drilling exists up dip and to the north of the Sinclair deposit itself. One of the few historic, shallow RC drill holes (CWWS003) that intersect the Sinclair ultramafic unit up dip of the main deposit intersected high-MgO ultramafic rocks and disseminated nickel sulphide mineralisation returning 2m @ 0.68% Ni from 78m down-hole.
Talisman believes that the potential exists for repeats of Sinclair-style mineralised environments up dip, and to the north of Sinclair itself in a similar manner to those parallel channels identified below, and to the south of, Sinclair at Stirling and Skye. Talisman plans to complete a series of RC drill holes along strike from the historic mineralised intercept ( Figure 5 ) to test the potential of the Sinclair ultramafic unit in the shallow environment.
Parnassus
At Parnassus historical drilling has intersected an additional interpreted basal contact position together with narrow intervals of disseminated nickel sulphides. Talisman will test the interpreted basal contact position for the presence of high-MgO ultramafic rocks and nickel sulphide mineralisation with two RC drill holes ( Figure 5 ).

Sinclair diamond core is HQ and NQ2 size, sampled on geological intervals (0.2 m to 1.2 m), cut into half (NQ2) or quarter (HQ) core to give sample weights under 3kg Samples were selected to weigh less than 3kg to ensure total preparation at the pulverization stage. RC samples are split using a cone or riffle splitter. A majority of RC samples are dry. On occasions that wet samples are encountered they are dried prior to splitting with a riffle splitter. Samples were submitted to ALS Chemex Laboratories for preparation. The sample preparation follows industry best practice where all drill samples are crushed and split to 1kg then dried, pulverized and (>85%) sieved through 75 microns to produce a 1g charge for 4-acid digest with an ICP-MS or AAS finish. QAQC protocols for all diamond drill sampling involved the use of Certified Reference Material (CRM) as assay standards. The insertion ratio of CRM standards was 1 in 25 with a minimum of 2 per batch. OREAS and Geostats standards were selected on their grade range and mineralogical properties.

Sinclair drill samples were submitted to ALS Chemex Laboratories in Perth for multi-element analysis using a 1g charge with a multi-acid digest and ICP-MS or AAS finish (OG62). Analytes include Al, Fe, Mg, Mn, S, Ti, Ag, As, Co, Cr, Cu, Ni, Pb, V, Zn, Zr. QAQC protocols for all drill sampling involved the use of Certified Reference Material (CRM) as assay standards. The insertion ratio of CRM standards was 1 in 33 with a minimum of two per batch. OREAS and Geostats standards are selected on their grade range and mineralogical properties. All drill 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 and reported on a monthly, quarterly and annual basis. Historic results for all standards and duplicates indicate most performing well within the two standard deviation limit. Lab checks (repeats) occurred at a frequency of 1 in 25. These alternate between both the pulp and crush stages. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
The Sinclair Nickel Project is held 100% by Talisman Nickel Pty Ltd, a wholly owned subsidiary of Talisman Mining Ltd. There are no known Native Title Claims over the Sinclair Nickel Project. All tenements are in good standing and there are no existing known impediments to exploration or mining. |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
The Sinclair Nickel Deposit was discovered in 2005 by Jubilee Mines NL drill testing a ground EM anomaly. M37/1275 hosts the Sinclair Nickel Mine which was operated by XNAO from 2007-2013 and produced approximately 38,500 tonnes of contained nickel metal. Exploration work on has included diamond, RC and Air Core drilling, ground and down-hole EM surveys, soil sampling, geological interpretation and other geophysics (magnetics, gravity). |
| Geology | Deposit type, geological setting and style of mineralisation. |
The Sinclair Nickel Project lies within the Archean aged Norseman-Wiluna Greenstone Belt. The Sinclair Nickel Deposit is an example of an Archaean-aged komatiite-hosted nickel deposit, with massive nickel-iron sulphides hosted at or near the basal contact of high-MgO ultramafic lava channels with footwall basaltic volcanic and sedimentary rocks. |
| Drill-hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill-holes: easting and northing of the drill-hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill-hole collar dip and azimuth of the hole down hole length and interception depth hole length. If the exclusion of this information is justified on the basis that the information is not material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
Drill hole information relating to the Sinclair Nickel Project is included in Table 1 Drill-hole Information Summary, Sinclair Nickel Project. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of |
Significant intersections reported from the Sinclair Nickel Project are based on greater than 0.5% Ni and may include up to 1m of internal dilution, with a minimum composite grade of 1% Ni. Ni grades used for calculating significant intersections are uncut. A minimum diamond core sample interval of 0.15m and a maximum interval of 1m is used for intersection calculations subject to the location of geological boundaries. Length weighted intercepts are reported for mineralised |
