Talisman Mine Maiden Ore Reserve Statement and Metallurgical Testwork
- 28,800 Oz Gold and 127,800 Oz Silver Ore Reserve for start-up phase of the mine development underpinned by Pre-feasibility Study
- Analysis of Pre-Feasibility Study Conducted by International Consultancy
Metallurgical Testwork and sampling
Recovery of visible physical gold and silver from metallurgical samples using non chemical extraction equipment recently purchased
Recent samples of Talisman ore tested by SGS showed up to 453g/t gold which was processed.
New Talisman Gold Mines Limited (NTL) is pleased to announce the maiden JORC compliant Ore Reserve for the Talisman Mine. Ore Reserves at the Talisman gold project, based on an average in-situ cut-off grade of 1.7g/t, are 82,500 tonnes at 10.8 grams per tonne gold and 48.1 grams per tonne silver. Ore Reserves are derived from and contained within, not additional to, the Measured and Indicated portions of the Mineral Resource. This ore reserve estimate reflects the outcome of the Pre-Feasibility Study conducted on Phase 1 of the Talisman Mine Project, and forms a solid basis for the company to proceed with further project development.
A gap analysis on the Pre-Feasibility Study was carried out by Hatch Goba. Hatch Goba is an employee-owned, multidisciplinary professional services firm that delivers a comprehensive array of technical and strategic services, including consulting, information technology, engineering, process development, and project and construction management to the Mining, Metallurgical, Energy, and Infrastructure sectors. Hatch has served clients for over 80 years and has project experience in more than 150 countries around the world. With over 11,000 people in over 65 offices, the firm has more than $35 billion in projects currently under management.
Based on the Hatch analysis NTL are confident that the Pre-Feasibility Study conforms to the requirements of a Technical Study as defined in the Joint Ore Reserves Committee Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves 2004 (the JORC Code).
While the volatility in gold price has affected other juniors gold operations particularly in New Zealand, New Talisman has continued to press forward. This has paid off with these positive results showing the potential for an accelerated development in getting Talisman into production. With the development of an ore reserve New Talisman has continued to de-risk the project on the path to bulk sampling and mining.
Significant progress has been made with regard to consents and we are confident that consenting arrangements will be finalised in the coming months.
The company has more recently entered into discussions with a major group for the toll treatment of the Talisman ore and test work and sampling is underway to test the suitability of the ore for processing by the potential treatment plant.
Matthew Hill Executive Director said “We continue with the company’s strategy to reopen the Talisman mine and the recent analysis of the Pre-Feasibility study by an international firm gives us great confidence in our pathway chosen and phased approach toward production. This is the first Ore reserve from Talisman since the mine was in full production many years ago.
With a difficult climate and depressed gold price felt by junior and major gold companies alike NTL has been able to deliver positive outcomes to our shareholders”.
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. Ore reserves are defined 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.
A technical report, titled “Ore Reserves Definition – Talisman Gold Project, August 2013”, in support of this maiden ore reserve statement has been prepared in accordance with the JORC Code. This technical report “Ore Reserves Definition – Talisman Gold Project, August 2013”, has been prepared at the request of the board of New Talisman Gold Mines Limited with the purpose of supporting the definition of a maiden Ore Reserve attributable to NTL’s Talisman Gold Project, based on the outcome of the Pre-Feasibility Study completed in March 2013. The report is for the general information of Directors and shareholders of the company, potential investors and for the general disclosure of information to the market and is a Public Report as defined under the JORC Code 2004. The full report is available on the company website.
Information on Mineral Resources has been sourced mainly from the companies own exploration activities. The Mineral Resource estimate used as the basis for conversion to Ore Reserve is set out in the public report titled“TALISMAN GOLD RESOURCE INCREASES TO 205,000 OZ” released to the market on 11 May 2005also available on the company website.
The Pre-Feasibility Study on which conversion of Mineral Resources to Ore Reserves is based, has been carried out and determined a mine plan that is technically achievable and economically viable; all material Modifying Factors have been considered.

Wayne Chowles, Principal Mining Engineer commented that “the rigorous approach taken in the Pre-Feasibility Study has identified a robust course of action to bring the Talisman asset to account. Upon initiating the bulk sampling program currently under application we are confident in our ability to develop a sustainable high grade mining operation. With areas such as the Mystery vein relatively untouched, NTL has the flexibility needed in the current climate for junior miners”
Metallurgical Testwork
The recent purchase of non-chemical recovery equipment to test samples recovered from Talisman has given us further insight into the various non-chemical processing routes which have resulted in recovery of sample amounts of physical gold and silver using gravity concentration and flotation techniques.
Samples were sent for chemical analysis at SGS New Zealand’s Waihi Laboratory with the following preliminary results:

Further testwork is in process to ascertain recovery efficiency.
The purpose of the testwork was to identify an efficient grain size required to extract and concentrate gold and silver using gravity and flotation methods. This information will assist in developing the most efficient route for the processing of the ore once mining commences.
