The Groundrush deposit (ML22934) became the Company's principal focus of activity following early significant results.

Exploration programs also focused on the extensions of known deposits within Mineral Leases MLS153, MLS167, MLS168 and MLS180. Included with this work were the historic Carbine and Hurricane open pits where the aim was to bring at least one of the prospects into a mineable Resource for inclusion in the Central Tanami Project Feasibility Study.


Diamond drilling continued at Groundrush targeting depth and strike extensions of the current Resource with several holes stepping out to the north and south of previous drilling, while also stepping down plunge of the main zone of mineralisation. 

The Groundrush Resource upgrade drill program has been underway since June 2012 with the key objective of advancing a significant portion of the Mineral Resource to an Indicated and Measured status with close spaced drilling. The purpose of this program is to provide adequate Resource confidence for mine design and planning which is scheduled for completion towards the end of 2012.

Significant intersections include:
(To review all drill intersections please see Quarterly Reports for period ending 30 June 2012 and 30 September 2012)

GRDD116 - 30.1m @ 9.0g/t Au, including 5.6m @  21.9g/t Au
GRDD100 - 31.0m @ 4.7g/t Au
GRRD103 -   5.1m @ 21.7g/t Au, 16.0m @ 3.9g/t Au, 9.2m @ 4.5g/t Au
GRRD63   - 38.4m @ 45.9g/t Au
GRRD74   - 17.0m @ 109.5g/t Au 


In addition, a comprehensive RC drill program commenced in December 2011 at the Ripcord Prospect located approximately 2 kilometres south east of Groundrush. The aim of this program was to delineate strike, depth and lateral extent of the existing zone of gold mineralisation, prior to an open pit Resource definition drilling program. Ripcord has geology and geophysics similar to Groundrush and has additional potential for deeper hidden gold mineralisation.

All results have been received from phase one drilling at the Ripcord Prospect. The RC program has successfully intercepted significant near surface mineralisation which remains open along strike and down dip. Of significance are the results returned from the most southern drilling line. Based on these results and as the mineralisation remains open along strike and at depth, follow up drilling has commenced.

Significant intercepts returned (to view all drill results, refer to ASX announcement dated 5 July 2012):

RPRC5 -   52.0m @ 2.14g/t Au from 24m and 11m @ 4.0g/t Au from 99m
RPRC6 -   12.0m @ 2.2g/t Au from 35m
RPRC8 -   20.0m @ 1.23g/t Au from 63m, including 8.0m @ 1.9g/t Au 
RPRC27 - 11.0m @ 3.7g/t Au from 71m
RPRC33 -   8.0m @ 4.9g/t Au from 27m
RPRC34 -   3.0m @ 10.8g/t Au from 109m
RPRC35 -   4.0m @ 6.7g/t Au from 168m


Diamond drilling has continued at the Carbine deposit, located at the north end of MLS 167. Carbine was identified as a key deposit in the Company's plans to recommence gold production from the Central Tanami Project, due to the robust widths and grades of previous intersections. Infill and extensional drilling of the deeper Resource area being targeted for future underground mining has returned a number of significant intersections including:  

CADD11 - 2.9m @ 5.1g/t Au from 144.2m
CADD16 - 7.6m @ 3.0g/t Au from 174.1m
CADD20 - 6.0m @ 5.1g/t Au from 376.0m
CADD21 - 9.6m @ 2.3g/t Au from 643.7m

The current drilling campaign will focus on extending the lodes at depth, along strike and at testing the shallower mineralisation beneath the northern end of the pit and north east strike extensions below a veneer of younger sedimentary rocks. Results from the deep drilling program will be incorporated into an updated mine design and Feasibility Study.


Hurricane was also identified as a key deposit in the Company's future mine plans due to its proximity to the plant and its robust mining characteristics exhibited by the remaining mineralisation.

Significant gold intersections include:

HRDD5   -   1.1m @ 17.8g/t Au from 372.6m
HRDD7   - 14.2m @ 3.9g/t Au from 396.5m, including higher grade core of 7.1m @ 5.9g/t Au from 400.4m
HRDD10 -   4.3m @ 4.4g/t Au from 377.8m
               -   2.6m @ 5.4g/t Au from 368.2m
               -   3.3m @ 8.6g/t Au from 251.7m
HRDD11 -   2.4m @ 8.1g/t Au from 361.7m
               -  25.2m @ 3.1g/t Au from 368.2m, including 5.1m @ 5.7g/t Au from 385.5m
HRDD14 - 30.2m @ 3.8g/t Au from 144m, including 6.0m @ 5.3g/t Au and 5.2m @ 10.1g/t Au

The results from this campaign at Hurricane confirm that mineralisation continues over 300 metres below the surface with strong potential to extend well beyond this level.   

While exploration at Hurricane is at an early stage, the drill results underline the potential for the Hurricane-Repulse deposit to be an important and significant contributor to the Company's long term production profile.
