Diamond testing of primary targets at BM1 to commence next week.
The directors of Encounter Resources Ltd (“ Encounter ”) are pleased to provide the first batch of assay results from the RC drilling program at the BM1 prospect at the Yeneena project.
Assay results have been received from the first 14 holes of a 33 hole RC program completed at BM1 in July 2011 (Figure 1). The drill program was completed at a nominal 80m by 40m spacing over the Northern Area mineralisation, with holes drilled to a vertical depth of approximately 100m. This program was primarily designed to determine the orientation and extent of the high grade copper mineralisation intersected in EPT0751 (10.1m @ 6.8% copper from 31.9m) .
“The RC drilling was highly successful and has confirmed the continuity of the oxide copper. The identification of a native copper and chalcocite zone on the westernmost section is particularly significant as it is an indicator to a possible copper sulphide zone at depth. The diamond rig will re-commence testing these primary sulphide copper targets from next week” said Managing Director Will Robinson
Details of the recent RC drilling completed at BM1 can be found in Table 1.

The mineralisation encountered in the RC drilling is hosted within the black shales of the Broadhurst Formation that have undergone varying degrees of weathering. This ranges from subtle oxidation within the supergene zone to complete leaching within sections of the oxide zone. The higher grade intercepts within the oxide zone are coincident with areas of greater silicification where the mineralised horizon is more resistant to surface weathering and leaching.
The drilling has confirmed the mineralised horizon is generally flat lying through the central core of the Northern Area and then dips off to the west and to the east. This observation supports an earlier interpretation that the overall geology of the BM1 area is dominated by an open antiform that appears to plunge gently to the north.
The western line of RC drilling has intersected significant copper mineralisation below the carbon oxidation front at depths between 50-95m from surface (Figure 2). This indicates the western limb of the antiform is dipping to the west. The mineralisation along this section is dominated by chalcocite and native copper. The progression from malachite dominated mineralisation in the oxide zone to chalcocite and native copper in the supergene zone is typical of the weathering profile of a copper sulphide deposit. This provides a vector to a possible copper sulphide zone further west and at depth.

Drilling along the easternmost section has also intersected copper anomalism below the carbon oxidation front based on handheld XRF results. The anomalism is located at depths from 35-80m and indicates a gentle easterly dip to the eastern limb. The anomalism along this section has provided a second vector to possible primary copper sulphide mineralisation. Assays from this line of drilling are pending.
A schematic cross section has been drafted to illustrate the overall interpreted geology across the Northern Area mineralisation (Figure 3).

Project Background & Location Plan
The BM1 prospect is one of several high quality prospects within the 100% owned Yeneena project. The Yeneena project covers 1300km[2] of the Paterson Province in Western Australia and is located 40km SE of the Nifty copper mine and 30km NW of the Kintyre uranium deposit (Figure 4). The targets identified are located adjacent to major regional faults and have been identified through electromagnetics, geochemistry and structural targeting. The targets are hosted within sediments of the Broadhurst Formation in a similar geological setting to the Nifty copper deposit (total resource of 148.3mt @ 1.3% Cu – Straits Resources Ltd, 2001).
