Ann: Siren Significantly Extends Mineralisation at Big River, page-7

Is that what you meant? Massive sulphides in the footwall?

11.4grams per tonne gold in the footwall?


"The A2 shoot is in a second anticline 200m to the west of the Sunderland anticline (Figures 4 & 5). Mapping and
channel sampling identified outcropping quartz reef up to 1m thick surround by sulphide rich sediments which
contain lenses of massive sulphide in the footwall. Channel sampling indicate that the quartz reef is relatively
low grade, but the footwall mineralisation assayed up to 11g/t Au.



"Five diamond holes drilled into the A2 shoot tested 100m strike to a depth of around 25m. Drillhole BRDDH020
intersected 4m stope (possible mined quartz reef), a 2m low grade zone then 5m @ 4.15g/t Au in the footwall
from 24m. BRDDH022 - BRDDH024 were drilled along strike to the north (Figure 4)."

These holes intesected a 10m wide zone with lower grade gold mineralisation but with the same high arsenic and sulphur mineralisation.
BRDDH023 has very high sulphur averaging 10.9% over 8m with a high of 36% over 1m.

4.42g/t, 21.9g/t, 18.5g/t 8.8g/t gold, some excellent gold results below. Are there any base metals in the sulphur?


Previous holes drilled around mine level 3 in shoot 4, including BRDDH03 (2m @ 12.1g/t Au), BRDDH05 (5m @
3.2g/t Au) and BRDDH027 (6m @ 5.1g/t Au), have a single reef intersection, while deeper drillholes have two
intersections indicating that there may be a hangingwall and footwall reefs in this area that may extend at depth
(i.e. BRDDH04, 4m @ 4.42g/t Au from 128m and 6.6m @ 21.9g/t Au from 136m; BRDDH09, 3m @ 18.5g/t Au
from 147m and 7m @ 8.8g/t Au from 158m; and BRDDH12, 3m @ 5.4g/t Au from 170m and 3m @ 2.0g/t Au
from 205m).
