Welcome to Burrendong Minerals Limited

The Silica Hill Project has an Inferred Mineral Resource reported in accordance with the JORC Code (2012) of ~

18,000 oz gold and ~2,000,000 oz silver – See Table 1

 for the independent Geological Report for further details and Competent Person statements.

The mineralisation at Silica Hill lies between 60 m and 200 m north east of the Commonwealth deposit and comprises of a stockwork of veins and disseminations of gold, silver, zinc, lead and copper minerals typical of certain epithermal styles of mineralisation. Visible silver minerals such as proustite and pyrargyrite are common. The mineralisation is hosted by a large flow banded rhyolite flow or sill with large phenocrysts of quartz and feldspar throughout the unit. Within the rhyolite is a second porphyry unit of a different composition that separates the two main zones of mineralisation.

The Silica Hill Resource strike length is 500 metres and it is open along trend in particular to the south. The mineralisation has been defined to a maximum depth of 290 metres and is still open.

The Mineral Resources comprises two limbs, one being south-south west dipping lode (South Lode) that truncates a north-northeast steeply dipping lode (North Lode). These Mineral resources have a total strike length of 240 metres and extend vertically to about 190 metres below surface for the North Lode and to 290 metres below surface for the South Lode. The horizontal width is variable ranging from 4 metres to 40 metres and averaging 20 metres where the two limbs are separate and 75 metres wide where the two limbs join. Thirty four drill holes (10 RC and 24 diamond), have been completed at Silica Hill, all drilled by Impact. Of these holes, 32 intersected the mineralisation wireframe and were used in resource estimation calculations.

Silica Hill is a virgin discovery by Impact Minerals and is located 60 metres to 250 metres north east of Main Shaft. The mineralisation comprises a North Lode and South Lode both comprising high grade veins and disseminations of sulphide with gold and extensive visible silver minerals (antimony and arsenic sulphosalts: proustite-pyrargyrite). These minerals are exceptionally rare in Australia and contribute to some exceptional silver grades in specific veins.

There are also zinc and lead credits to the mineralisation at Silica Hill with the sulphides present being similar to those at Commonwealth-Main Shaft. They are interpreted as being part of the same overall mineralised system. The disseminated mineralisation between the veins has helped form thick zones of near-surface modest grade mineralisation with the potential for bulk open pit mining. As indicated in the Independent Geologists Report (refer to Schedule 3), three diamond drill holes completed by Impact Minerals have also established that there is a low grade silver halo of up to 10 g/t silver around the Silica Hill mineralisation that is at least 500 m by 500 m in dimension. By example, Hole CMIPT072 returned 146 metres at 0.04 g/t gold and 5 g/t silver, whereas Hole CMIPT078 drilled at the eastern end of the northern mineralised zone returned the thickest intercept of gold and silver to date in this zone recording 117 metres at 0.3 g/t gold and 11 g/t silver.

These results attest to the scale of the mineralised system at Silica Hill which is still open in all directions and further deeper drilling is required as illustrated in Figure 1 below.

In conjunction with the planned drilling of the Commonwealth trend, the Company will at the same time, look to complete a number of diamond/RC drill holes within the Silica Hill trend. As indicated in Figure 1, the mineralisation is open at depth and also presents a very large target zone. The Company believes that the planned drilling of the indicated target zones will substantially increase the Mineral Resource already established. To that end, the Company has submitted an application for Approved Prospecting Operations (APO) with the objective of substantially increasing the Mineral Resources already established. Drilling sites to accomplish this objective have been selected and these are illustrated in Figure 2.
