Interim assay results for 2011 drilling programme

Tri-Star Resources (AIM: TSTR) is pleased to provide details of the first tranche of assay results provided by its drilling contractor, Spektrajeotek AS, in respect of its diamond drilling programme being undertaken at the Company's antimony Goynuk property in western Turkey.

Highlights

·      The drilling performed to date has returned confirmation that the antimony (Sb) mineralisation discovered at Goynuk in 2010 is persistent and extends to the South-East of the property.

·      The drilling programme is ongoing and further announcements will be made as more assay results are received and when results are fully analysed and independently verified.

Brian Spratley, Chief Executive Officer of Tri-Star Resources, commented:

"I am delighted to announce that the drilling programme at Goynuk is advancing and the initial assay results have shown positive results.

"These assay results are a good indication of the high grades associated with the mineralisation at Goynuk and we are pleased that the silicification and alteration hosting the mineralisation appears to be contiguous between most of the holes.  We are all looking forward to extending the drilling programme and the areas of demonstrated mineralisation."

Drilling assay results

A programme of diamond drilling was commenced on 15th July 2011 by the Company's contractor to test for the continuation, or repetitions of, the known antimony (Sb) mineralisation discovered in boreholes GOY10001, GOY10002 and GOY10004 drilled in 2010 at the old Goynuk mine. 

The 2011 drilling programme has been concentrated on the South-East extension area, which is a new mineralised zone lying sub horizontal and down dip of the old Goynuk mine workings. The drill programme commenced with diamond drill hole GOY11021, which was drilled to test basement sediments but which was not sampled.

A total of 27 holes have been drilled to date, of which the first 11 drilled in the South-East zone  were sampled and are reflected in these results, with the [selected] assays shown in Table 1 below indicating the high grades encountered, notably at the following drill holes:

·      Hole 22 - 10.00 metres of 1.92% Sb with a high value of 7.07% Sb

·      Hole 24 - 5.30 metres of 8.02% Sb with a high value of 18.25% Sb

·      Hole 28 - 6.30 metres of 4.04% Sb with a high value of 13,.80% Sb

·      Hole 29 - 2.00 metres of 4.82% Sb with a high value of 7.58% Sb

·      Hole 32 - 2.00 metres of 2.29% Sb with a high value of 4.12% Sb

The drilling has been laid out to intersect the mineralised area on lines running North-West to South-East (300 degrees azimuth to the North-West and 120 degrees azimuth to the South-East). By varying the dip of the holes, a grid of approximately 15 metres by 15 metres has been created.

The contractor is using HQ drilling equipment which results in approximately 72mm diameter core, with recovery being very satisfactory.  The recovered core is logged on site and selected core samples are cut in half and sent for assay. The residual half core is retained at site.

The samples were initially taken to the ALSGlobal laboratories in Izmir, on the west coast of Turkey, where they were crushed, pulverised and prepared for assay, and were subsequently delivered to the ALSGlobal laboratories in Vancouver for assay.
