GARDEN GULLY SHAPING UP
Thundelarra has carried out two work programmes at Garden Gully. Phase 1 was scout drilling (28 holes for 2,278m) that delivered visible gold at Lydia and identified 11 significant geological targets. Phase 2 was 29 Reverse Circulation ("RC") holes for 6,432m, together with associated Down Hole Electromagnetic ("DHEM") surveys, following up the first nine of the targets. The results and interpretation of the data gathered so far show Garden Gully has the potential to be a significant new gold discovery in an area that has hosted several major gold mines over the years. The Lydia, Transylvania, Battery and Granite Well prospects are shaping up as the four main project targets for immediate follow up.
Numerous gold-mineralised intervals from the drilling to date demonstrate the potential.
Significant gold intersections so far:- Lydia: 6m at 2.8 gpt Au from 49m in TGGRC15 7m at 24.5 gpt Au from 11m in TGGRC18 37m at 1.8 gpt Au from 71m in TGGRC26 4m at 3.8 gpt Au from 97m in TGGRC32 8m at 1.8 gpt Au from 120m in TGGRC32 14m at 2.2 gpt Au from 216m in TGGRC33 15m at 1.6 gpt Au from 243m in TGGRC33 80m at 1.9 gpt Au from 79m in TGGRC34
- Transylvania: 6m at 2.9 gpt Au from 103m in TGGRC22 8m at 1.7 gpt Au from 69m in TGGRC24 7m at 1.4 gpt Au from 107m in TGGRC44
- Battery: 5m at 2.0 gpt Au from 115m in TGGRC42 9m at 1.5 gpt Au from 163m in TGGRC52 8m at 2.0 gpt Au from 164m in TGGRC53
- Granite Well: 31m at 0.3 gpt Au from 71m in TGGRC04 8m at 2.2 gpt Au from 44m in TGGRC48 4m at 2.6 gpt Au from 56m in TGGRC51
- Five potentially mineralised off-hole conductors to be tested
- Geological settings intersected are very similar to those hosting known gold mineralisation nearby (Andy Well, Dalgaranga)
- Start of follow-up drilling is imminent

Table 1. Details of the holes drilled at Garden Gully in the Phase 2 follow-up RC programme. All locations on Australian Geodetic Grid GDA94-50. The azimuth shown is the magnetic azimuth of the drilling direction.
Results of most of the holes drilled at Lydia, Battery, Transylvania and Granite Well were reported in announcements dated 03 November 2016, 19 January, 08 February and 13 February 2017.
Assay results from the balance of the holes not previously reported can be found in Appendix 1.
At Lydia, holes TGGRC035 and 036 reported several zones mildly anomalous in gold and arsenic: TGGRC035 was collared to the west of where the other holes have shown the prospective trend to be, and the hole was drilled away from the prospective zone. TGGRC036 was drilled to test one possible structural orientation. Evaluation shows the hole was drilled subparallel to the main trend.
The three holes drilled at Ascuns were test an interpreted black shale package that offered potential for a possible VHMS-style setting. Interpretation of the mapping and geophysical surveys carried out in conjunction with the drilling have shown that the original interpretation incorrectly placed the geological contact tested by the drilling several hundred metres west of its currently interpreted position. Several zones of highly anomalous zinc values were intersected but the area will need to be re-evaluated in light of the new data gathered from the exploration carried out. The principal zone of interest - the tectonic contact between the black shale environment to the west and the resistive greenstone terrain to the east - will be drill-tested again in future programmes.
The four holes drilled at Sabbath were designed to test for possible southerly extensions to the Booty / Transylvania mineralisation and to provide additional information on the most prospective locations and trends for more detailed future follow-up testing. TGGRC056 intersected primary gold mineralisation with anomalous arsenic (7m at 0.6 gpt Au, 414 ppm As) from 124m down hole. The position of the zone initially interpreted to be a prospective shear zone, which coincided with several historical workings, has been adjusted based on the data gathered. It now appears that the old workings were developed in transported cover and the geophysical survey data is indicating that the prospective zone appears to be located further to the west than tested by this programme. This will require re-testing in future programmes.
The geological data from the Phase 2 drilling indicates that the Transylvania, NE Transylvania, Booty and Sabbath prospects appear to be associated and will now be known collectively as Transylvania.
Preparation for Phase 3 follow-up drilling to test the Lydia, Battery, Transylvania and Granite Well prospects is well advanced. Thundelarra will advise the market as soon as the programme starts.
