  • JU-11-34: 18.75m grading 4.71g/t gold and 32g/t silver or 5.16g/t Au_eq from 60.35m downhole including 8.45m at 9.18g/t gold and 61g/t silver or 10.04g/t Au_eq from 60.35m downhole and a narrow high grade interval of 0.65m grading 10.30g/t gold and 73g/t silver or 11.34g/t Au_eq from 73.85m downhole.

Troy Resources is pleased to announce the following:

In 2010, Reverse Circulation "RC" drilling produced two encouraging gold assays intervals on the Southern Vein system. These included; RC-10-38 with 8.0m at 6.96g/t Au_eq from 33.0m plus 5.0m at 3.55g/t Au_eq from 52.0m and 3.0m at 5.66g/t Au_eq from 81.0m; and RC-10-39 with 12.0m at 9.86g/t Au_eq from 44.0m and 3.0m at 6.65g/t Au_eq from 60.0m. These intercepts are open down dip/plunge. Diamond Core "DC" Drilling commenced at the Julieta Main Zone in March 2011 with the current program testing the area below the existing Resource. The objective of testing the possibility at depth for a change in vein mineralogy from calcite dominant to more silica dominate and a change in vein texture changes hopefully associated with an improvement in grade. This drilling is targeting the vein systems at depths between 40.0m – 80.0m below the existing drilling.

The first three 2011 DC drill holes were planned to test this potential northwest trending vein system: Holes JU-11-32 to JU-11-35 targeted the Southern Vein set at the Julieta Main Zone.

Significant assay intervals include:

JU-11-32; 0.65m at 2.85g/t au and 65.0g/t Ag or 3.78g/t Au_eq from 62.40m downhole.

JU-11-33;12.7m grading 4.54g/t gold and 18g/t silver or 4.80g/t Au_eq from 56.75m to 69.4m downhole including 2.0m at 6.73g/t gold and 37g/t silver or 7.25g/t Au_eq from 56.7m to 58.75m downhole and 1.8m grading 19.24g/t gold and 66g/t silver or 20.18g/t Au_eq from 61.6m to 63.4m downhole.

Additional mineralised intercepts in JU-11-33 include 1.96m at 1.96g/t gold and 7g/t silver or 2.06g/t Au_eq from 85.5m – 86.5m as well as 4.7m at 0.95g/t gold and 3g/t silver or 0.98g/t Au_eq from 94.5m to 99.2m downhole.

JU-11-34: 18.75m grading 4.71g/t gold and 32g/t silver or 5.16g/t Au_eq from 60.35m to 79.1m downhole including 8.45m at 9.18g/t gold and 60g/t silver or 10.04g/t Au_eq from 60.35m to 68.8m downhole and a narrow high grade interval of 0.65m grading 10.30g/t gold and 73g/t silver or 11.34g/t Au_eq from 73.85m to 74.5m downhole.

JU-11-35: 4.76m grading 4.24g/t gold and 43g/t silver or 4.85g/t Au_eq from 84.34m downhole and 4.68m at 2.54g/t gold and 29g/t silver or 2.96g/t Au_eq from 94.1m downhole.

The current program will include a test of the Northern Vein system at depth (see Figure 1, Figure 2, Figure 3 and Table 1).

Commenting on the news Troy's CEO, Paul Benson said: "These results are significant for Troy as we are seeing ore grade intercepts at Julieta. Although at depth, the topography at Julieta is such that this mineralisation could be accessed by a short adit from an adjacent valley and thus the hurdle for development in terms of minimum size is relatively low.

"The results are also strategically very important. Julieta lies at the other end of the property from the existing Reserves at Kamila. The Julieta Main Zone and Kamila Deposit are about 5kms apart on the main northwest - southeast trending fault structure that we know played a key role in the emplacement of the mineralisation.

"We obviously will need more drilling to delineate the Resource potential of the Main Zone at Julieta, but it does prove we now have ore grade intercepts at both ends of the main 5km northwest – southeast structural corridor at Casposo. We have identified and mapped in detail outcropping veins for 1km of this corridor immediately southeast of Julieta, known as the Julieta SE Target, that will be drill tested. Between Julieta SE and the mine area we have more than 4kms of the structure that is masked by a thin layer of younger volcaniclastic cover. Thus, even if mineralised veining does occur along the full strike length of the structure, it is impossible to identify with surface prospecting and mapping. We are currently planning detailed airborne magnetics to be followed by ground IP geophysical surveys to identify drill targets below the volcanic cover.

"The results are also important because they demonstrate what we have been saying about the need to systematically drill test veins at depth to identify the boiling zones - the "sweet spots" associated with higher grade gold and silver mineralisation. The Julieta veins have anomalous gold at surface and we have now seen higher grades and thicknesses at depth. This is significant because we have numerous outcropping veins with anomalous gold values reported from channel sampling with little or no drilling on the Casposo and Castaño Nuevo properties. All of these are targets that need to be ranked and systematically drilled."
