Summary Exploration title EL29029 was granted to Darwin Mining & Exploration PTY LTD on 6 June 2012. During the last twelve months, geological reconnaissance has been carried out in October and early November. Two local people had been organised to join us for the geochemical sampling using their vehicals or motorcycles because our hired vehicle was not suitable to drive into the bush. Unfortunately, the local people were not available when we first arrived in the field in October 2013. For this reason, we had to change our schedule. Three weeks later when we returned, the locals had had an accident and could not go with us. A short geological reconnaissance was undertaken by us. We failed to access Clark Cu1-3 old mining area with our hired vehicle and did not find the old Ringer mine. Twelve rock chip samples were taken from the Mt Irene old pit area by us on foot. It was slow and ineffective. We had to give it up and plan the sampling for next year.

Geological Setting Geologically EL29029 sets at Mount Doreen Mineral Field in the Arunta Region of the Aileron Province. The major rock types include Mesoproterozoic-Paleoproterozoic variably metamorphosed clastic sediments, meta volcanic rock, calc-silicate rocks, dolerite, mafic rock and intrusion granite. Minerals hosted by the rocks include metamorphosed VMS and carbonate replacement Pb-Zn-Cu, iron- oxide Cu-Au, orogenic Au, W(-Mo), Sn, mafic-hosted Ni-Cu, vermiculite, hydropthermal U, and apatite- and pegmatite-hosted REE-U(-P). Major explorations in the region target for base metals, Ni-Cu, uranium, mafic-hosted vanadiferous magnetite, REE and orogenic gold. Unfortunately, still large areas remain significantly under-explored.

Reconnaissance and Mineralisation in the tenement of EL29029

Mineralisation occurring in the tenement of EL29029 and adjacent area includes tungsten at Mount Doreen mine, base metal (Cu-Pb-Zn-Ag) at Silver King mine, Tungsten at Ringer mine, base metal (Cu-Pb-Zn-Ag) at Mount Irene mine and Clark Cu No’s 1,2 &3 mines (Fig. 2).

It had been planned to take geochemical samples systematically at the eastern Silver King mine area along the northern wing of the big fault where there is an uranium anomaly (Fig. 3) and high contents of uranium in the rock chip samples taken by Rio Tinto Ltd in 1998 (Fig. 4).

Unfortunately the local’s we organised had to travel away for a funeral when we arrived to the field in October 2013. When we returned three weeks later, the local’s had an accident and were not able to do the sampling for us.

In this case we carried out the geological reconnaissance ourselves on the western mineral occurrences; Ringer W mine, Mount Irene and Clark Cu 1,2 &3 base metal mines which we failed to access by our hire vehicle previously. Due to the local’s not being available, we had to use the hire vehicle again. Like before, the vehicle could not be driven in the bush and we had to walk several kilometers to the sites each day. We failed to access Clark Cu No’s 1, 2, & 3 mines and the Ringer W mine. The Ringer W mine area is all flat and the old mine pit could have been refilled as the mine has been closed for decades. Only the Mount Irene old mining area was visited during the reconnaissance. A shallow old open pit can be seen (Fig. 5).

Some abandoned ore had been found several metres away. Most of the ore are iron rich, like gossan sample, with some malachite (Fig. 6).

Generally the ore bodies are present in small size stockwork or small veins which are controlled by a shear zone. Twelve samples have been taken from the old open pit and near the area. The results are listed in the Table 2.

During the field investigation, geologists had to walk on foot for several kilometres to the mining sites without the help of the local people. It took so long for the field investigation and the program was ineffective on foot. Eventually, Darwin Mining and Exploration P/L geologists run out of time in the NT and had to give up the further investigation and leave all the work for next year with help from the local people.

Work Planned

1. Geological survey and sampling in the Ringer tungsten mine and Clark Cu 1,

2 & 3 base metal mines which we failed to find and access; 2. Geochemical and geophysical methods will be used to target subsurface

structures, unexposed granite and associated mineralisation if the initial reconnaissances in the area returns interesting results;

3. Ground investigation of the major E-W fault and its secondary shears at south of the Silver King Mine. Rock chip and soil geochemical sampling will be carried out.

4. Testing the anomalies targeted by geological, geophysical and geochemical surveys by drilling.
