    .... just read the announcement... !! Hooray!!!!!!

    Maybe someone (SWC?) at the meeting should move a special Vote Of Thanks to Tony for the huge effort he is putting in that benefits all of us shareholders.!!

    Here is an interesting exercise.

    Examining the three cross-sections shown in the latest announcement (p4,5,6) . They are (in sequence) on three Eastings 7850, 7800, 8000.

    It would have been better to list them in the correct order.... 8000, 7850, 7800 so the change in section as you progress along strike to the SW could be better visualised. Anyway...

    1. The section at N-S Line 637850E is projected as solid and wide sulphide. It is the result of 8 holes!! and hence is drawn with high confidence.

    RVD-02A, RVD-02, AAND-01, AAND-13, AAND-12, RVD-06, NRV-00-02, AAND-44

    It does not particularly show an improvement of grade with depth, but that is OK as AAND-44 suggests any amount of 1% at depth (and open)!! Richer zone 3-6%Cu is actually 50 - 100m below surface.

    2. The section at 638000E is really the result of only one hole AAND-37. AAND-39 appears to be drilled a bit too far south to be in the action, and the small shallow intercept it has is likly to be 0.13% - 0.37% Cu, as per nearby assay. However the last hole AAND-41 should be very revealing as it is on the other (active) side of AAND-37. Look forward to an update of this cross section when AAND-41 result is included.

    One thing this hole demonstrates is a big improvement in grade as depth increases! 0.4% through to 7% (incl some 26%) at 120m below surface.

    Plotting AAND-41 (285) on that section is easy. It finishes below and goes right through the 7-26% zone. IF it strikes more of the same grade, 100m below the other, wow! we shall see!

    3. On line 7800E, Cu grades maximise again at 70m below surface, and then go the usual 1%+ at depth. Again it is open at depths below surface of 100m so lots of 1% ?

    OK... I tried to plot the next section 32, 34, 36 but two are still at lab.

    ... then next one... 30, 28, 38
    30 contains nothing as could be expected. 38 is at lab and 28 is a big disappointment. It is almost on that latest VTEM hot-spot. So unless it was too shallow and too far south and missed, it is a mystery perhaps... but I am no geo.

    then....

    Finally the question. For each step-out along strike of 50m which represents say 3 holes, what gain is there in copper metal?

    Allow for 35m width of deposit, then reduce section by say 0.8 to allow for it not being at right angles to strike. Then guess(!!) at a nominal depth of 130m and step out of 50m

    So 35 x 0.8 x 130 x 50 x 2.5 t/m3 x 1%Cu (ignoring shallow oxide)

    4500 t of copper-in-sulphide per each 50m step-out along strike. Conceivably.

    Very Rough. And would need verification by those here who are technically much more savvy, before taking it as gospel.... but it is a discussion point I guess.

    Excellent news today. A BIG step forward.
