Ganajur Main gold resource increases 16%<br />
Outcropping of gold-bearing rocks at Deccan’s Ganajur Main project.<br />
<strong>The</strong>re are an estimated 93,000 tonnes of inferred resources in the<br />
sulphide zone @ 1.82 grams/tonne for 5000 ounces and a further<br />
17,000 tonnes in the oxide zone @ 3.26 grams/tonne for 2000<br />
ounces. <strong>The</strong> total inferred resource is now estimated at 109,000<br />
tonnes @ 2.06 grams/tonne for 7000 contained ounces.<br />
<strong>The</strong> new estimate is limited to the material that has reasonable<br />
prospects for eventual economic extraction by constraining this within<br />
an optimized pit shell. <strong>The</strong> modelled gold zones extend from surface<br />
to a depth of about 120 metres and the resources are reported at a<br />
cut-off grade of 1.0 gram/tonne gold.<br />
Deccan Gold Mines has also carried out comprehensive metallurgical<br />
studies at the AMMTEC Laboratory in Australia as part of the<br />
scoping study. <strong>The</strong> results are being studied in association with SRK<br />
to derive a suitable flow sheet and plant design for a proposed processing<br />
plant at Ganajur Main with a daily capacity of 2000 tonnes.<br />
<strong>The</strong> Government of Karnataka has issued an order agreeing to allot<br />
land and water required for the establishment of a gold processing<br />
plant near Ganajur and Deccan is working with local authorities to finalize<br />
a site. <strong>The</strong> mining lease application of Deccan’s subsidiary, Deccan<br />
Exploration Services Private Ltd, over the Ganajur Main prospect<br />
and covering an area of 0.29sqkm is under consideration of the Indian<br />
Government’s Ministry of Mines to whom it was recommended by the<br />
State Government of Karnataka.<br />
THE mineral resource at Deccan Gold Mines’ Ganajur Main gold<br />
prospect in southern India has increased by more than 16% to 308,000<br />
ounces, of which more than 90% is in the indicated category. <strong>The</strong> revised<br />
estimate is part of an ongoing scoping study at the prospect to<br />
evaluate the economic viability of an open pit mine at Ganajur Main.<br />
<strong>The</strong> JORC-compliant estimate was prepared by SRK Mining Services<br />
India, which estimated the initial resource statement for the project<br />
in 2010. Deccan retained SRK in February 2011 to undertake a<br />
scoping study to assess the mining potential of the prospect, which<br />
is in the Ganajur-Karjagi Block of Haveri district in the State of Karnataka.<br />
This process has involved Deccan carrying out further exploration,<br />
including infill and step-out drilling.<br />
<strong>The</strong>re are now estimated to be 1.921 million tonnes of indicated resources<br />
in the sulphide zone @ 3.83 grams/tonne gold for 237,000<br />
contained ounces and 631,000 tonnes in the oxide zone @ 3.19<br />
grams/tonne for 65,000 contained ounces. This makes for total indicated<br />
resources of 2.552 million tonnes @ 3.67 grams/tonne for<br />
301,000 ounces.<br />
