Savoyardy Gold Project
Savoyardy Gold Project
Kentor Gold has successfully rehabilitated the existing underground workings which were constructed during the 1970’s. Approximately 150 metres of underground development was also undertaken in 2008 to allow access to additional areas for drilling. Approximately 1,300 metres of railway was constructed in the underground workings to allow transport of the drill rigs and removal of the broken waste rock from the development headings.
Both the underground mining contractor and the diamond drilling contractor performed well with no injuries and all planned work being completed on budget and on schedule.
The drilling encountered mineralisation both above and below the level of the existing adit (entrance). The surface diamond drilling defined an additional parallel mineralised structure to the east of the Rudny mineralisation where the initial gold Resource is located. The surface drilling also demonstrated that the high grade mineralisation continues along strike to the south west of the main zone. Sampling of the backs and walls of the drives was also undertaken.
The initial Resource estimate for the project at Rudny was completed using the results from the drilling and channel sampling.
The Resource estimate was reported in compliance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC code) and is based on 43 diamond drill holes and 335 underground channel samples in the Rudny area of the Savoyardy exploration licence (Figure 1). The Resource estimate was completed by Hellman and Schofield Pty Ltd.
The Resource was estimated using Multiple Indicator Kriging and is shown in Table 1 at a variety of cut off grades. The estimates have been based on the assumption that the deposit will be mined by underground hand held mining methods using the existing development and possible hand sorting of ore.

Figure 2 (above) shows the grades of the resource blocks greater than 3 g/t gold. The existing mine development provides immediate access to the ore.
The gold mineralisation at Savoyardy is mainly hosted by fractured sandstone units within a weakly metamorphosed Devonian clastic sequence. The mineralisation occurs as gold-bearing massive and veined pyrite and arsenopyrite in proximity to fault structures.
Induced polarisation geophysical surveys were conducted over the Rudny area of the Savoyardy exploration licence. The survey has generated a number of promising targets to be followed up with drilling in 2009.
Metallurgical test work was carried out on a bulk sample from Savoyardy. The results showed that high recoveries of gold (94%) could be achieved using gravity and flotation concentration to produce a high grade concentrate (50 g/t gold) for sale to third parties.
Flotation test work on Savoyardy ore.
 The metallurgical test work was conducted at the AMMTEC laboratories in Perth and was supervised by Metallurg Pty Ltd. The test work program included crushing, grinding, gravity separation and flotation to produce sulphide concentrate(s). Further treatment of the gravity and flotation concentrate products was undertaken by testing refractory process routes such as ultra-fine grind(UFG)/CIL, two-stage roast/UFG/CIL, and the Activox Process (oxidation/UFG/CIL) The results of the metallurgical studies have been used to design the optimum flow sheet for the project and to estimate capital and operating costs required to process the Savoyardy ore in to a saleable product.
A pre-feasibility study, aimed at examining the possibility of bringing the Savoyardy project into small scale production in 2010, is now in progress and is expected to be completed by April 2009. The capital costs are expected to be low due to the use of contract mining to access the ore body through the existing underground development. Treatment of the ore will also be carried out using locally available contractors who have equipment available and experience at crushing, milling and flotation operations.
In 2009, Kentor Gold plans to complete the pre-feasibility study for the project and also continue to add to the size of the gold resource at Savoyardy through extending the drilling along strike and commencing the definition of other areas of mineralisation previously identified within the exploration licence.
Kentor Gold is earning a 70% interest in the Savoyardy Property from Manas Resources by spending US$6m before 2012.
Competent Persons Statement:
The data in this report that relates to Exploration Results, the accuracy and quality of data forming the basis of all resource estimates, and the interpretation of mineralisation at Savoyardy, are based on information compiled by Mr Craig Irvine who is a Member of The Australasian Institute of Mining and Metallurgy (MAusIMM) and who has sufficient experience relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the “JORC Code”). Mr Irvine was a full-time employee of Kentor Gold Ltd during the undertaking of the exploration work. He is now a full time employee of Newcrest and he consents to the inclusion in the report of the Mineral Resource in the form and context in which they appear.
