Market Announcement

For Immediate Release

HIGHLIGHTS

• Value of Talisman project more than doubles on results of

updated Pre-Feasibility Study, NPV

9% increases from $15m to

$36m;

• Recovered gold increases by 50% to 51,000 Gold Equivalent

Ounces;

• Direct operating costs to produce an ounce reduced to $710

NZD per ounce ($490 USD/oz)

• Ore Reserves increase by more than 40% from 30,500 to

44,100 Gold Equivalent Ounces;

• Independent valuation confirms robustness of the project

with a value of between NZ$8.4M and NZ$21.4M

New Talisman Gold Mines Limited is pleased to announce the results of the updated

Pre-Feasibility Study on the Talisman Gold Project. The results of the study, as set out

in this announcement, reaffirm that the establishment of a highly profitable, small-scale

operation, focused on extraction of the higher confidence Measured and Indicated

Resources accessible from 8 Level,

should provide for an excellent return on

investment.

CEO Matthew Hill stated “The updated study demonstrates the robustness of the

project economics, showing an IRR of 118% demonstrating the significant value to

investors of this world class mine. With a scoping study on Talisman Deeps being

finalised in the coming days on the high grade resources and activity at the mine

ramping up we are starting to see the results of the teams hard efforts. ”

In summary, revision of the 2013 Pre-Feasibility study in light of new information has

demonstrated an increase in the Net Present Value, (NPV) from NZD15.4m to

NZD35.9m at a 9% Discount Rate. The key drivers for this increase in value are discussed

below:

1. Increased ounces available for extraction – this is a result of the 2017 (JORC 2012

compliant) Mineral Resource Estimate which saw gold equivalent ounces in the

Measured and Indicated categories increase by some 18,000 ounces. These are

included in the mining plan which has seen an increase in expected gold production

of some 18,800 Oz AuEq.

2. Increased mine life – on the back of the increased ounces life of mine is extended

by a year giving a current expectation of 6 years for this first stage of the larger

project;

3. Grade – Run of Mine grade, on a gold equivalent basis, has increased from 11.2g/t

to more than 27 g/t.

4. Breakeven gold price reduced substantially to $820 NZD per ounce.

5. Unit operating costs significantly reduced with costs to extract the ore and bring it

to surface (C1 cost) of NZD 583 per ounce and cost to produce an economic ounce

of gold (C2 cost) being NZD710 per ounce. With the NZD gold price currently sitting

at NZD1882 per ounce this demonstrates the robust nature of the project.


UPDATED ORE RESERVE STATEMENT AND PRE-FEASIBILITY STUDY RESULTS

6. Independently sourced long term nominal annual average forecasts for gold range from US$1,334/oz in

2018 to US$1,374/oz in 2022, with longer-term (2023-2027) averaging US$1,440/oz.

7. NZ$:US$ exchange rates used in the financial model were based on forecast rates obtained from the

National Australia Bank and the Economy Forecast Agency these point towards a general decline in the

exchange rate which is expected in a range from 0.69:1 to 0.60:1

The outcome of this study supports a 50% increase in the Ore Reserve attributable to the Talisman Mine. Ore

Reserves, based on an average in-situ cut-off grade of 2.6 g/t, are 45,000 tonnes at 30.6 grams per tonne

gold equivalent. Reserves are quoted at the point of delivery to the gold processing plant and are derived

from and contained within, not additional to, the Measured and Indicated portions of the Mineral Resource.

The study was reviewed by independent experts who found that the proposed mining plan is appropriate for

the style of deposit at Talisman, and that determination of Ore Reserves has been attained through

reasonable evaluation of mining costs and process recoveries.

Chief Operating Officer Wayne Chowles stated ”the revised plan is the culmination of several years of

refinement and presents a very solid technical case for development of this world class asset. The robust

economics and low environmental impact of the project make it an absolute winner!”

Supporting Mineral Resource Estimate

In late 2016 the Company began a programme to upgrade the Mineral Resource estimate to be compliant

with JORC 2012 reporting standards. This exercise was prompted by the acquisition of a large database of

historic geological and geochemical information relating the deeper extents of the Maria Vein. Information

on this estimate was released to the market in three modules covering the Dubbo, Woodstock and Talisman

Bonanza zones of the Maria vein.

Figure 1 - Long Section of the Maria vein showing the Woodstock Zone on the left, Dubbo on the right and

Talisman/Bonanza in the middle.

The net result of this exercise was to revise the estimate of mineral resources available to the Talisman

Project from 917,000 tonnes at 6.9g/t Au for 204,000 Oz Au to 950,000 tonnes at 15.1g/t AuEq for 469,000

Oz AuEq. Full details of the methodology can be found in the individual company releases of 12 July 2017, 25

July 2017 and 05 September 2017. Final results are tabulated below:

Mineral Resources Talisman Mine

Category Tonnes AuEq g/t AuEq Ounces

Measured 102,800 17.4 57,480

Indicated 97,700 7.4 23,100

Inferred 750,000 15.9 389,200

Total Resources 950,500 15.1 469,800

Completion of this process considerably enhanced the company’s understanding of the geometry and grade

distribution within the orebody and it was considered necessary to revisit and update the Prefeasibility study

on the Talisman Project, which was previously completed in 2013 (PFS13), in order to examine the design

and modifying factors incorporated in that study. The Company further elected to commission a scoping

study on the Talisman Deeps project which will be the subject of a separate release.

Of note is the fact that in the historical data no individual grades for gold and silver are reported and for

consistency, data integrity and comparison with modern sampling it was decided to carry out the resource

estimates using gold equivalents.

During the period of historical mining the gold price stayed constant at £4-6s-0d per oz, (USD20.47) while

silver ranged from USD0.49 to USD1.03 per oz. Metallurgical recoveries once cyanidation was used were in

the 95% plus range.

In order to make the comparisons between modern channel and drill hole sampling and historical sampling

the ratio calculated used the formula Au equivalent = Au g/t +(Ag g/t *0.031609).

An independent third party reviewed the data and modelling used by NTGM for the Talisman mine Mineral

Resource estimates and Ore Reserves. They completed sufficient checks to ensure that the databases used

for the resource modelling are accurate and consider that the modelling and resource estimation processes

were undertaken in a professional manner to acceptable industry standards and with due consideration of

the validity and quality of the historical data.

They further consider that the 2017 MRE Report and the Appended JORC Code Table 1 contain the majority

of relevant information that investors and their professional advisers would reasonably require for the

purpose of making a reasoned and balanced judgement regarding the Mineral Resources being reported and

is compliant with JORC 2012 reporting standards.

Pre-Feasibility Study Overview

A Preliminary Feasibility Study (Pre-Feasibility Study) is a comprehensive study of a range of options for the

technical and economic viability of a mineral project that has advanced to a stage where a preferred mining

method, in the case of underground mining, is established and an effective method of mineral processing is

determined. It includes a financial analysis based on reasonable assumptions on the Modifying Factors and

the evaluation of any other relevant factors that are sufficient for a Competent Person, acting reasonably, to

determine if all or part of the Mineral Resources may be converted to an Ore Reserve at the time of reporting.

A Pre-Feasibility Study is at a lower confidence level than a Feasibility Study.

The Pre-Feasibility Study on which conversion of Mineral Resources to Ore Reserves is based, has been

carried out and has determined a mine plan that is technically achievable and economically viable, material

Modifying Factors have been considered.

The first step of re-evaluating PFS13 took the form of revisiting the mine design for the Dubbo and Woodstock

Zones where new information was likely to affect the initial parameters. Examination of the geological model

revealed that significant changes were required to the mining infrastructure to allow meaningful extraction

of the very high grade measured and indicated resources. Particularly the highly mineralised portion of the

Dubbo Zone indicated a shortened strike length while the dip extent was longer than previously thought

which necessitates additional legs of the decline and incline system.











Sublevel open stoping remains the mining method of choice as it offers the greatest flexibility and can

accommodate a range of drilling techniques dependent on the variability of the orebody. Development of

the access ramps and sub levels is maintained on reef as far as possible to offset the cost of development.

Figure 3 - Diagram showing previous and revised layouts for Dubbo Zone. The revised layout includes two

additional sub levels.

These drives are, of necessity, placed in the low-grade portions of the orebody which are unlikely to present

an economic target

In determining the economic viability of the mine plan, the following modifying factors were considered:

Mining Factors

Cut off grades - these were based on a preliminary assessment of the likely direct mining costs. A

grade/tonnage curve was used to estimate the likely applicable cut-off grade to achieve the required

Run of Mine, (ROM) grade. These cut off grades have been calculated for each portion of the resource

depending on the individual grade/tonnage relationship of the block.

Mining Method - An option analysis identified sub-level stoping as the most appropriate mining

method which offers the flexibility to adapt to both mechanised and traditional drill and blast

techniques. Excavations required to access each zone, appropriate to the intended method, have

been designed inclusive of drives, traveling ways and ventilation passes.


Geotechnical Parameters - Maximum stope span has been limited to 35m. Strike and dip pillars have

been designed to a hydraulic radius, (HR) of 1.4 which is well above the existing HR of 0.9 observed

in stable pillars immediately adjacent to the planned stopes.


Dilution – Planned dilution of between 9% and 15%, dependent on orebody geometry, has been

included in the modelled stope wireframes. An additional 6% of total stope tonnage has been

allowed as “unplanned dilution” to allow for scaling etc.


Mine Recovery – a 10% loss of metal has been allowed for in the calculations to account for ore

permanently locked up in stopes.


Minimum Mining Widths - No minimum mining widths have been applied as all veins modelled are

equal to or exceed 1.0m in width which is acceptable for removal by the envisaged mining method.

Visual inspection of existing stopes indicates that stope widths of <0.6m are attainable within this

environment.


Utilisation of Inferred Mineral Resources - The study has focused primarily on extracting ore

contained within the identified Measured and Indicated Resources. Some 13% of total tonnage

mined in the plan is extracted from Inferred Resources and is derived from development for

exploration purposes. This tonnage is mined in the last 2 years of the plan. Further to this a portion

of ore reporting to the plant is obtained from on reef development conducted in blocks not classified

as mineral resources as the grade falls below the cut-off grade. This ore does defray costs of

development and contributes positively to project economics.


Infrastructure requirements - Preliminary design of all supporting infrastructure including power

supply, compressed air and water reticulation, ventilation and ore transport is considered and

quantified in the study

.


Metallurgical Factors and Assumptions

The study proposes gold recovery via a gravity concentration and flotation system. This is supported by

testwork carried out on Talisman ore by Pocock and Simpson in December 2017 and announced to the

market on 22 March 2018. This testwork concluded that gold recovery exceeding 94% is achievable through

this process. A recovery factor of 90% is applied in the study to reflect the likely lower silver recovery through

the process.

Environmental

The company currently holds resource consent for a bulk sampling programme, this consent considers the

likely environmental impact of the operation and concludes that the effects would be no more than minor.

The effects of the larger operation are similar to those inherent in the bulk sampling project and no further

adverse effects are likely.


Infrastructure

Talisman is situated within a well-developed area with sufficient accommodation available. The site has a

reasonable infrastructure as a result of being an active mine for more than a century. The hard stand area is

connected to the main tarred road via a gravel road considered adequate for truck sizes up to 10t. 11kVa

power is available to site but will need to be reconnected, sufficient water is available on site to support the

mines requirements.

Costs

Costs associated with provision of capital infrastructure were derived from supplier quotes and costs

available from other mining groups. Operating costs were estimated from first principles based on detailed

costs for employment, personnel training, security, consumables, transport, administration, power, water

and other services.


Commodity Prices

Forecast commodity prices have been taken from Consensus Economics Inc.’s Energy & Metals Consensus

Forecasts , which surveys more than 40 energy and metals analysts every month for a range of commodity

price forecasts. Long term nominal annual average forecasts for gold range from US$1,334/oz in 2018 to

US$1,374/oz in 2022, with longer-term (2023-2027) averaging US$1,440/oz.

A comparison was made with forecasts drawn from The Economy Forecast Agency, while there were

variations in annual forecasts, overall, the two forecast sources resulted in insignificant difference to the

financial model.

Exchange Rates

NZ$:US$ exchange rates used in the financial model were based on forecast rates obtained from the National

Australia Bank and the Economy Forecast Agency these point towards a general decline in the exchange rate

which is expected in a range from 0.697:1 to 0.601:1 over the coming years.

Sensitivity Analysis

In order to understand the sensitivity of the project to various inputs the items shown in the following table

were varied in the ranges set out in

Table 1 below, the results are presented graphically in Figure 4.

Figure 4 - Sensitivity analysis

The consolidated line in the above graphic shows the effect of all items in table 1 occurring i.e. Capex and

Opex exceed budget, the gold price is below forecast, and gold recovery is less than anticipated. This would

be considered as an extreme alignment of circumstances and, demonstrates the robust nature of the project

where an NPV of 15.4m is indicated.

Ore Reserves

Mineral Resources are converted to Ore Reserves via the application of a range of technical and economic

factors (modifying factors) such as metal prices, dilution and estimated recovery, in order to assess project

viability. The 2012 JORC code defines ore reserves as follows:

Ore Reserves are those portions of Mineral Resources which, after the application of all mining factors result

in an estimated tonnage and grade which, in the opinion of the Competent Person making the estimates, can

be the basis of a viable project, after taking account of all relevant Modifying Factors. The relationship between

Mineral Resources and Ore Reserves is illustrated in the following graphic.



Mineral Resource and Ore Reserve categories are tabulated below.

An independent third party review of the PFS found that the mining plan proposed in the supporting techno-economic

study is appropriate for the style of mineralisation found at the Talisman and that determination of Ore Reserves has

been attained through reasonable evaluation of mining costs and process recoveries.

at prevailing speed limits and estimated l/hr consumption. Diesel price was

the current market price

• Refining charges are included, there are no penalties applicable

• Government royalties at 1% of revenue are included in the financial model

Revenue

factors

• The derivation of, or assumptions made regarding revenue factors including

head grade, metal or commodity price(s) exchange rates, transportation

and treatment charges, penalties, net smelter returns, etc.

• The derivation of assumptions made of metal or commodity price(s), for the

principal metals, minerals and co-products.

• Detailed calculations of mine ore flow, inclusive of all modifying factors,

were carried out to support head grade estimates. Recovery rates are based

on historical mine achievements using the same process as proposed.

• Forecast commodity prices have been taken from Consensus Economics

Inc.’s Energy & Metals Consensus Forecasts, which surveys more than 40

energy and metals analysts every month for a range of commodity price

forecasts. Long term nominal annual average forecasts for gold range from

US$1,334/oz in 2018 to US$1,374/oz in 2022, with longer-term (2023-

2027) averaging US$1,440/oz..

market windows for the product.

• Price and volume forecasts and the basis for these forecasts.

• For industrial minerals the customer specification, testing and acceptance

requirements prior to a supply contract.

• Not Applicable


• Not applicable

Economic

• The inputs to the economic analysis to produce the net present value (NPV)

in the study, the source and confidence of these economic inputs including

estimated inflation, discount rate, etc.

• NPV ranges and sensitivity to variations in the significant assumptions and

inputs.

• Inputs regarding metal prices, recovery etc. are described above. A 9%

discount rate has been applied to determine project NPV

• Sensitivity analysis was carried out varying the Capital, Operating Cost and

Metal Price in a ranges of -30% to +30%. The project maintains a positive

NPV under these scenarios although it is most sensitive to gold price

movements

Social

• The status of agreements with key stakeholders and matters leading to

social licence to operate.

• The company is in an advanced stage of negotiations with key stakeholders

Other

• To the extent relevant, the impact of the following on the project and/or on

the estimation and classification of the Ore Reserves:

• Any identified material naturally occurring risks.

• The status of material legal agreements and marketing arrangements.

• The status of governmental agreements and approvals critical to the

viability of the project, such as mineral tenement status, and government

and statutory approvals. There must be reasonable grounds to expect that

all necessary Government approvals will be received within the timeframes

anticipated in the Pre-Feasibility or Feasibility study. Highlight and discuss

the materiality of any unresolved matter that is dependent on a third party

on which extraction of the reserve is contingent.



A risk analysis has been carried out and is included in the Technical Report.

The mine is held under New Zealand Mining Permit no 51-326. The

company holds resource consent from local government and is permitted to

carry out bulk sampling activities which are similar in scope to those

proposed in this study. The company holds an access agreement and

authority to enter the land with the Department of Conservation


Classification

• The basis for the classification of the Ore Reserves into varying confidence

categories.

• Whether the result appropriately reflects the Competent Person’s view of

the deposit.


• The proportion of Probable Ore Reserves that have been derived from

• Measured and Indicated Resources have been classified to Proved and

Probable Reserves respectively

• This result reflects the Competent Persons view on the deposit. Measured

resources are readily accessible with low capital requirements. The Reserve

Estimates amount to a conversion of approximately 48% of the Measured

and Indicated Resources which is considered acceptable for this type of

deposit

Audits or

reviews

• The results of any audits or reviews of Ore Reserve estimates. • None carried out to date

Discussion of

relative

accuracy/

confidence

• Where appropriate a statement of the relative accuracy and confidence

level in the Ore Reserve estimate using an approach or procedure deemed

appropriate by the Competent Person. For example, the application of

statistical or geostatistical procedures to quantify the relative accuracy of

the reserve within stated confidence limits, or, if such an approach is not

deemed appropriate, a qualitative discussion of the factors which could

affect the relative accuracy and confidence of the estimate.

• The statement should specify whether it relates to global or local estimates,

and, if local, state the relevant tonnages, which should be relevant to

technical and economic evaluation. Documentation should include

assumptions made and the procedures used.

• Accuracy and confidence discussions should extend to specific discussions of

any applied Modifying Factors that may have a material impact on Ore

Reserve viability, or for which there are remaining areas of uncertainty at

the current study stage.

• It is recognised that this may not be possible or appropriate in all

circumstances. These statements of relative accuracy and confidence of the

estimate should be compared with production data, where available.

• The approach followed to convert the Mineral Resource to an Ore Reserve

as discussed in the Public Report is a robust approach and technically sound

for this type of deposit. The modifying factors applied in the conversion are

considered appropriate to the mining methods considered. The tonnages

relevant to each category of Reserve are set out in the report
