Market Announcement

For Immediate Release

QUARTER HIGHLIGHTS

 Sampling results from Mystery Vein show extension of

high-grade gold and silver mineralisation following

initial refurbishment and sampling

 Auxiliary fan commissioned and loading at Dubbo Zone

underway

 Development of the Keillors 8A return airway

commences

 Blasting Extraction and stockpiling continues

underground

 Access to Dubbo Zone advances substantially


The beginning of the 2019 calendar saw another busy quarter at the Talisman

mine with great strides being taken to secure access to the BM37 Rise in the

Dubbo Zone area. Following completion of refurbishments and testing of the face

at Mystery the focus this quarter has been on gaining access to Dubbo and

finalising resource consent for pilot plant operations. While the Dubbo area has

been slower to progress than expected the material removed to date shows

significant promise as set out in this report. Over the next quarter the company

will focus on progressing further into Mystery vein extension, moving ore to the

pilot plant for processing and making safe the Dubbo area in order to commerce

sampling of the vein faces.

Following the initial proving of the vein extension at Dubbo all underground resources were mobilized

to gaining access to this high grade area. Access was gained into the Dubbo area during the quarter

and revealed extensive excavations with refurbishments needed prior to extraction of samples from

the exposed vein. Following the end of the period the team had progressed the excavations and

improvements.

Now that access has been gained to Dubbo and the program of works needed in order for the team

to safely access the vein has commenced, technical resources have been deployed to the blasting and

excavation activities at Mystery and commencement of metallurgical testwork to determine

requirements for a higher volume plant.


Dubbo Zone Access

With installation of the underground auxiliary fan complete, the fan has been commissioned and air

ducting in place through the single-entry Dubbo extension of No 8 Level, mobile machinery was

deployed to the BM37 Cross-cut to commence loading of waste rock so that clearing access to the

BM37 rise could get underway. This zone was identified by borehole BM37 which assayed 656 g/t Au

over 1.8m including 1154 g/t Au over 1.0m and was the location of the last mining activity to take

place under the mines previous owners in the late 1980’s.

Initial inspection of the area indicated that there had been a fall of ground in the on vein rise at the

end of BM37 Cross-cut, completely blocking access to vein.



As loading progressed it became apparent that the hangingwall in the excavation had fallen against a

fault zone, filling the rise with fine material that was overlain with large blocks of andesite. Removal

of the material was complicated by the presence of a wooden scaffold, previously erected to gain

access to the rise above, which acted as a canopy preventing the free flow of rock from the excavation.

Sufficient rock has now been removed to allow partial access to the rise and a small area of the vein

exposure. From preliminary inspection of the size and physical conditions further up in the area, it is

apparent that the rise extends approximately 15m upwards at a dip of approximately 80 degrees and

has been opened to approximately 8m wide along the strike of the vein. There is also evidence of two

drives extending north and south from the base of the cross-cut along the vein although the complete

strike extent of these cannot be measured as yet. The vein itself is evident in the upper part of both

drives.

Support requirements have been assessed and a staged approach has been adopted to making the

area safe for human access. Stage 1 of this programme involves the construction of wooden and steel

sets from the brow of the cross-cut extending into the lower portion of the rise at approximately the


5

elevation intersected by the BM37 borehole. This will allow the remaining rock to be removed from

the base of the cross-cut, which will, in turn, provide access to the vein material exposed on the faces

of the Northern and Southern drives and sampling of this material will get underway. The sets will

also provide a platform from which work can commence on removing remaining rocks hanging up in

the rise and constructing a suitable platform from which to work in these very difficult conditions.

To date, from the Dubbo area alone, approximately 200 tonnes of rock, comprising mainly host

andesite mixed with fine vein material, has been removed from the area using a small bogger and

handheld equipment. Where possible the quartz has been trammed separately from the andesite.

Where larger sized blocks of ore could be identified they have been removed and are stored separately

for later testing in the pilot plant. Assays of grab samples from run of mine ore have ranged between

trace and 515g/t gold for an average of 34.8g/t Au, and trace and 4070g/t silver for and average of

296g/t Ag.

Representative samples have been taken of broken ore removed from northern face and removed to

rom stockpile Has yielded grades between 2.65g/t and 130g/t gold for an average of 36g/t Au, and

between 35g/t and 441g/t silver for an average of 146g/t Ag.

Dubbo Return Airway and Second Escape

Development of the Dubbo Return Airway continued, an additional flat blast was taken to attain the

position where the inclined end will begin. This drive will connect Keillors Cross cut with the BM37 rise

to provide a route through which air will return from the Dubbo workings and will also create a second

escape route from the area. This incline is targeted to intersect the Maria vein approximately 15m

above the existing Dubbo extension and, from that point, will follow the vein to the intersection of the

BM37 rise.

Mystery Vein

Due to the focus on the Dubbo area during the quarter, work on the Mystery Vein Northern Drive was

limited to the removal of the waste rock left behind during the first stage of the resue mining method.

This has proven effective and, with the opening of Dubbo area for access now nearing completion,

resources will again be directed towards advancing this drive with ore moved to ROM stockpile. The

Mystery Vein poses the most significant potential for expansion given the positive results achieved on

proving the extension of high grade gold and silver mineralization.

The Mystery Vein was discovered in the 1980’s, by then operator Cyprus Mines Corporation in joint

venture with New Zealand Gold Fields Ltd, when developing Keillors Crosscut to connect the Talisman

Mine with the adjacent Crown Mine. This cross-cut intersected a previously unidentified vein, now

called Mystery Vein, approximately mid-way between the historically productive Maria and Crown

vein systems. It is believed that this vein had not been identified previously because of its location on

the boundary between the two historic mining permits, although there is evidence that the vein may

have been encountered in the lower levels of the Talisman Mine. The vein has been exposed over a

strike length of some 50m and regular sampling carried out by New Talisman (then called Heritage

Gold) identified samples on the face of Mystery with grades of up to 50 g/t. Recent check sampling of

ore exposed at the drive face yielded grades of up to 40 g/t Au (please see

https://www.asx.com.au/asxpdf/20180508/pdf/43tvlpmv420f4f.pdf. )

The Mystery vein shows similar geological characteristics to the adjacent veins and follows a similar

north south strike direction, suggesting that this may be the same vein system worked at the historic

Rhoderick Dhu Mine which is located roughly mid-way between the Talisman and Crown Mines

around 100m below the current exposure on No 8 Level. Current activities at the Talisman prioritize

enhancing the Company’s understanding of the full extent of the vein given its potential to be a major

contributor to mine life.

Metallurgical Testwork Pilot Plant

Commissioning of the pilot processing plan has been delayed by land use consent applications which

are being processed. All components of plant have arrived and are awaiting assembly off site. It is

anticipated that resource consent issues will be resolved by end May following which the plant can be

commissioned. In the interim the ROM stockpile continues to grow and will remain stored inside the

mine until the plant is operational. One aim of this test batch is to prove that the required precious

metal recovery rates can be achieved and any potentially acid forming minerals can be removed from

the waste material leaving a chemically inert commercially viable by-product.

While the capacity of the pilot plant is relatively low the aim is to replicate the recovery rates which

were achieved using a similar flowsheet in the testwork carried out in South Africa in February 2018

(please see https://www.asx.com.au/asxpdf/20180322/pdf/43sn63s00fjnz6.pdf ) . Once recovery

rates are confirmed a larger plant, suitable for the longer-term needs is planned, dependent on other

options as the company continues to assess enquiries regarding altenative potential treatment

options.
