DRILL RESULTS EXTEND DEPTH OF SPRING HILL GOLD
THOR MINING PLC
DRILL RESULTS EXTEND DEPTH OF GOLD MINERALISATION
SPRING HILL GOLD PROJECT
Dated: 17 September 2012
The Board of Thor Mining Plc ("Thor") (AIM, ASX: THR), is pleased to advise that further assay results have now been received from the 2012 Spring Hill drill program at its Spring Hill Gold Project south of Darwin in Australia's Northern Territory.
Highlights include:
• SHDD008B 8.4m at 1.47 grams/tonne (g/t) gold (Au) from 189.5m
including: 0.5m at 5.45 g/t Au from 189.5m
and: 0.25m at 22.73 g/t Au from 193.0m
3.0m at 4.70g/t Au from 217.8m
including: 0.6m at 22.1 g/t Au from 219m
39.7m at 0.49 g/t Au from 326.2m
• SHDD010 7.0m at 2.34 g/t Au from 385m
including: 1.0m at 12.73 g/t Au from 387m
21.0m at 1.02 g/t Au from 397m
including: 3.0m at 4.08 g/t Au from 404m
and: 1.0m at 2.12 g/t Au from 417m
· Refer to Table 1 for the full report of significant intersections including estimated
true widths for assays received to date
The results for these two holes indicate depth extension in the order of 100m to the gold mineralising system for the Hong Kong lode. Resource estimation modelling will follow final assays to determine the grade distribution within the lode.
Commenting, Mr Mick Billing, Executive Chairman of Thor Mining, said,
"This is an encouraging extension to the known mineralisation at Spring Hill. While we do not have all the assays from the program and therefore cannot speculate on any possible resource extensions, it is encouraging to confirm the extensions to the mineralised system."
Project Equity - Thor to increase to 51%
Expenditure at Spring Hill has exceeded the amount required for Thor to exercise its option to increase its equity to 51%, and notice has been provided to joint venture partner Western Desert Resources (WDR) which has commenced a verification review of that expenditure.
Drilling of the initial six holes is now complete and all samples have been dispatched for assay. Final assay results including the remaining assays for holes 9 through 12 are not expected until late September. Logging of the core has not indicated further significant veining, however not all Spring Hill mineralisation has a strong veining association.
Callie Mineralisation Model
The drill hole to test for Callie style mineralisation beneath the existing Spring Hill resource, SHDD009 was completed. The hole successfully intersected and tested the structural target which comprised the sheared Spring Hill anticline axial plane. Despite the final hole depth of 922 metres the hole was unsuccessful in reaching the Koolpin Formation stratigraphic target.
Assays have not yet been received however based on visual inspection of the core it is unlikely that significant mineralisation was intersected. The hole demonstrated that at the northing of the known Spring Hill mineralisation, any Callie style mineralisation, if it exists is at a depth which is beyond likely economic extraction. The mineralising model is still valid and is scheduled for testing in future programs, along strike to the north as the stratigraphy shallows.
Satellite Targets
A high resolution helicopter based magnetic (helimag) survey was conducted over the Thor tenements in July2012. This data which has now been received and processed will be used to finalise targeting of drilling to test satellite resources once permitting has been finalised.

Intersection selection criteria:
· Intersections are calculated using 0.2 g/t gold cutoff with a minimum interval of 1 metres and maximum of 3 metres internal dilution
· High grade intersections (shown in bold) are calculated using 2 g/t gold cutoff with a maximum of 3 metres internal dilution
· 'Interval' refers to the down-hole length of intersection
· 'True width' is estimated from the outline of mineralisation interpreted on the relevant cross section
