The Woolgni Project is prospective for gold mineralisation and consists of one of the eight NT Tenements (EL31457).
The Woolgni exploration licence covers a Lower Proterozoic inlier of Burrell Creek Formation, in early Carpentarian Cullen Granite. The Carpentarian Edith River Volcanics appear to have pierced the Cullen Granite and Burrell Creek Formation and in places, extrusives have flowed to form a cap over the older units (Figure 4).

Historical mining extends over several hundreds of metres in the prospective Burrell Creek Formation which also hosts several significant historical gold mines. Previously, exploration has been confined to a series of generally shallow (< 80m) Reverse Circulation (RC) and diamond core (DDH) drill holes. These holes have targeted higher grade quartz veining beneath old workings.
Figure 5 shows the location of the drilling and trenches at the Woolgni Project. The old workings, combined with the recent drilling and trenching, delineate the prospective mineralised zone within the anticlinal structure.

Historical mining and exploration have delineated gold in a structural setting typical of most Pine Creek gold deposits. The Company proposes to expand upon this geological model to explore for and define additional gold mineralisation. Initial work will focus on establishing survey and topographical control over the Project area. Structural and lithological mapping over prospective areas will enable a more refined targeting process as gold mineralisation tends to be focussed on anticlinal axes. This will allow planning of drilling programs to follow up historic exploration results.
RC drilling is planned to target zones of broad mineralisation rather than narrow, individual quartz veins. The target of this exploration strategy is a larger, lower grade deposit similar to other defined gold deposits in the Pine Creek region. Following the RC drilling, and depending on results, a diamond core drilling program will be designed to enable more detailed structural data to be collected and to provide samples for bulk density and metallurgical test-work.
Each step in the proposed exploration program will be conducted contingent upon the success of the preceding activity.
