PHASE ONE OF THE SUMMER HILLS DRILLING PROGRAM COMPLETE
HIGHLIGHTS
-
Five diamond holes drilled – four at Dalcouth and one diamond tail at Extended confirm geological model at the Summer Hills Mining Lease
-
This is Phase One of a three phase program to further define an early and easily mineable resource close to the Mt Veteran Mill, in order to provide near term cash flow generation

-
Like previous programs at Summer Hills it was shallow (approximately 50 metres vertical depth) and did not attempt to test the mineralisation at depth.
-
Encouraging tin intersections including:
-
3.8m @ 0.4% (DDHDAL104) between 17 and 21m, including 1m @ 0.72%
-
5m @ 0.43% (DDHDAL108) between 33 and 38m, including 1m @ 1.0%

-
2.8m @ 0.32% (X23 tail) between 59.2 and 62m, including 1m @ 0.4%. This extends the mineralised zone at the bottom of the original hole to 5m @ 1.0% between 57 and 62m.
-
An extensive brecciated zone was identified in all four Dalcouth holes which correlates with the mineralised zone
-
The rhyolite porphyry dyke was intersected

Overview
MGT Resources Limited (MGT or the Company) is pleased to announce that Phase One of the 2013 drilling programme at the Dalcouth and Extended Prospects has been completed, comprised of five diamond holes (230m).
Both prospects lie within mining lease 20547 “Summer Hills” which surrounds the Mt Veteran Tin Processing Plant, and is 86.48% owned by the company, through its subsidiary MGT Mining Limited.
The Dalcouth prospect is approximately 500 metres from the plant. The resource is shallow (down to approximately 50 metres), the host rock is easy to drill and it has favourable metallurgical characteristics. The Company’s strategy is to prove up sufficient tonnages at Dalcouth to provide near term cash flow generation.
The diamond drill holes were drilled through the centre of the main Dalcouth mineralised zone to improve our understanding of lithology, structure and mineralisation. The holes were also essential for providing geotechnical information. A diamond tail (30m) was also drilled at the end of percussion hole X23 at Extended, to close off the mineralised zone at the bottom of that hole.
The Dalcouth prospect
Drilling commenced on the 23[rd] April and was completed on the 3[rd] May. This is the first phase of a three part drilling program. Phase Two of the program was recently completed with assay results pending. This phase was a reverse circulation (RC) program. MGT geologists were able to use initial petrographic studies on the core from the Phase One diamond holes to help plan Phase Two. Planning of Phase Three (follow-up RC holes) will be completed when the assay results from Phase Two are returned, allowing the new information to better target follow-up holes.

+Cut-off grade of 0.1% used to delineate intersections. Assaying of half-case samples was conducted initially by Australian Laboratory Services Ltd using a pressed pellet XRF technique (XRF05). Samples that returned a value of >1000ppm were reanalysed using the ore-grade fused disc XRF technique (XRF15b). These results are reported in percentages and are more accurate than the ppm results reported for the XRF05 analysis.
Brecciated Zone at Dalcouth and porphyry dyke intersections
The diamond holes at Dalcouth intersected a wide brecciated zone, which appears to be associated with the rhyolitic porphyry dyke and is roughly correlatable with the higher grade mineralised zone present in the central part of the deposit (see figures 1-7). The plotted mineralised zones appear to be locally offset which may have taken place along one of the faults that have been mapped at surface. Further structural interpretation is necessary to determine if this is the case.
Diamond Tail at Extended
A diamond tail was drilled from RC hole X23 which ended in mineralisation. Samples from the bottom 3m of the RC hole averaged 1.68% Sn. The diamond tail showed that this mineralised zone extended for a few more metres, bringing the overall intersection to 5m @ 1.0% between 57 and 62m. A mineralised vein was intersected at 87.4m with that metre returning *0.27% Sn. Results from the tail at Extended suggest that the mineralised zone may be narrow but high grade with significant mineralisation also carried in veins through the system.
*further analysis is planned on this interval as there was a difference between the assay values for the original sample and a duplicate sample from that metre – 0.27% is the mean value.
