BIG PIT INITIATIVE DRILLING RESULTS
Summary
Westonia Mines Limited releases the first batch of assay data from its current Big Pit Initiative drilling program.
Best results from the first 12 holes are:
WDD 104: 150 - 220m, 70m @ 3.2 g/t (Figure 1) WDD 108: 166 - 188m, 22m @ 10.8 g/t WDD 111: 186 - 202m, 16m @ 6.4 g/t
The recent acquisition of the Big Bell mill will enable a 2.5Mtpa treatment rate of Westonia ore. That accelerated rate has brought forward the plan to undertake further drilling below the Base Case pit which the Company is using for completion of its bankable feasibility study ("BFS"), so as to determine potential for increased project longevity. At depth beyond that pit, the Company's drill database indicates a general continuity of mineralisation which has been used to estimate resources, but the present drill density is insufficient for estimation of mineable reserves.
The Big Pit Initiative will entail infill drilling up to 44 RC and diamond holes. The results from the first 12 holes assayed are as tabulated. The positions of the holes are shown on Figure 2.
The BFS is due for completion this quarter. Subsequent resource and reserve estimates will incorporate the new drilling commencing in December.

Notes:
- All assays are preliminary. Assaying is by a partial extraction technique and a a) small upwards correction will generally be applied in due course.
- b) Diamond tails are still required for WDD 105, 107 and 112. WDD 109 and 110 are currently being drilled and/or assayed.
- C) No cutting has been employed.
- d) All holes are vertical, or inclined towards grid southeast.
- True widths will vary between 70% and 90% of downhole width. e)
The Company is encouraged by the results to date. The next release of assay information is planned to be at the AGM on 25 November.
