PERTH, WESTERN AUSTRALIA--(Marketwire - Oct. 12, 2011) - Troy Resources NL ("Troy") (TSX:TRY)(News - Market indicators) -
NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES
Troy Resources NL advises that further to the Casposo Resource Upgrade announcement released on 29 August 2011, an updated Technical Report (NI 43-101) has been completed as required by the Canadian Securities Regulators. The report documents the Resource additions at Kamila Southeast – Inca Vein Zone and the new increase to the Julieta Zone.
- Initial Mineral Resource Estimate for the Kamila Southeast – Inca Vein Zone Discovery of 119,900oz Au_Eq (Measured and Indicated – using 2.0g/t Au_Eq cut-off) and 51,000oz Au_eq of Inferred Resource includes a "high grade" Measured and Indicated core zone (5g/t Au_Eq cut-off) grading 6.6g/t gold, 796g/t silver or 18g/t Au_Eq for 113,100oz Au_Eq.
- This discovery represents a 19% increase in the Casposo Measured and Indicated Resource Inventory and more than doubles the contained gold equivalent ounces in the Underground Measured and Indicated Resource Inventory.
- A new Inferred Resource Estimate for the Julieta Zone has been calculated at 433,000t grading 4.0g/t, gold and 23g/t silver or 4.3g/t Au_Eq for contained metal of 55,700oz gold and 320,200oz silver or 60,300oz Au_Eq which is double the 2010 Inferred Resource of 268,700t grading 3.21g/t gold and 15.44g/t silver or 3.43g/t Au_Eq for 29,700 Au_Eq ounces.
- Casposo Updated Mineral Resources summarized in Table 1 and Table 2 below.
The updated NI 43-101 report for our wholly owned Casposo Project in Argentina can be found on the Troy Resources website (www.troyres.com.au) and under our profile on the SEDAR website (sedar.com).
Readers are cautioned that the Technical Report is principally focused on new Resource additions. The portions of the Report which are based on the Mining Reserve, being the mining schedule and project economic analysis, have not been updated because Troy has not yet prepared an updated Reserve for the Casposo Project. It is expected that a new JORC compliant Mining Reserve and corresponding NI 43-101 report will be released in early calendar 2012.
Commenting on the new Resource Troy CEO Paul Benson said; "Today's release updates the market on the Resource inventory at Troy's wholly owned high-grade Casposo mine in Argentina. In addition to the Resource estimate for the Kamila SE discovery that was reported to the market on August 29, 2011 the report includes the new Resource Estimate for the Julieta Zone, at the northwest end of the main Casposo structural corridor.
"The doubling of the Julieta Resource is a result of the inclusion of the 2011 "ore grade" drill intercepts announced earlier this year.
"Julieta is strategically important because we now have ore grade mineralisation 5km along the structure to the northwest of Kamila, 4kms of which has a thin layer of cover and has yet to be mapped or drilled. We are just about to commence geophysical surveys with the aim of prioritising drill targets along the structure.
"It is important to note the new NI 43-101 Report only updates the Casposo Resource estimate. The Company is currently completing the relevant work to update the Mining Reserve and production schedule. We expect these to be completed and announced to the market in early calendar 2012."
Troy and its Resource Estimation Consultants – Auralia Mining Consultants utilised computer software to construct three-dimensional solid shapes of the five domains. Top cuts were applied to gold and silver grades for all domains. Gold and silver grades are interpolated using an inverse distance squared (ID2) methodology.
The Qualified Person (QP) for the Mineral Resource estimates is Keith Whitehouse MAusIMM (CP) of Auralia Mining Consulting.

Au_eq grade calculated using gold to silver ratio of 1:70. As per May 2010 Current Casposo NI-4310 Technical Report. The gold equivalent cut-off was determined according to the parameters below: |
|
Au/Ag ratio 1:70.00 |
|
Au Price US$933.33/oz |
|
Ag Price US$15.50/oz |
|
Au processing recovery 93.7% |
|
Ag processing recovery 80.6% |
Gold equivalency is determined by metal price and recovery factors. |
Metal prices are the average prices assumed in the Casposo life of mine plan. |
Processing recoveries were determined by metallurgical testwork carried out by independent consultants on Diamond drill core from Casposo. |
The equivalency is calculated by the formula: |
Gold:Silver ratio = (gold price ÷ silver price) x (gold recovery ÷ silver recovery) |
|
= (933.33 ÷ 15.5) x (.937 ÷ .806) |
|
= 70.00 |
Gold equivalency is calculated by the formula: Au_eq g/t = Au g/t + (Ag g/t ÷ 70.00) |
NSR No significant Results All samples were prepared and assayed by Alex Stewart (Assayers) Argentina Laboratory in Mendoza, Argentina. |
|
Gold by FA and either a gravimetric or AAS finish, using method gold 4-50 or gold 4AAA50 for samples with gold>10g/t |
Silver by three techniques: four-acid digestion followed by AAS reading for check samples up to February 2006, aqua regia digestion followed by inductively coupled plasma with optical emission spectroscopy (ICP-OES) reading for all samples in mineralised intersections after February 2006. Method numbers were GMA, ICP-AR-39 and silver 4A-50. |
