Occasional thin beds of finer-grained, equally altered, sheared arqillites and siltstones

Greywackes - Facing direction by graded turbidite beds is up the hole - i.e. beds young to
the north. Dip of sediments is 65~70ON at 96m and throughout the hole. Sediments comprise
fine or medium grained greywackes with 2fc interbedded siltstone or argillite. Quartz veins are
all narrower than 1 cm, of bedding parallel character in 20^. and crosscutting, brittle
fracture type in 60& of the veins. Some 20^ are of near-bedding oriented foliation, dio
slip type; these latter contain carbonate and fragments of stronqly sheared sediments.

the finer sediments. Thin quartz-Co3~(sericite) veins parallel this foliation
strike, but dip 55 south (93m). A second set of thin (1mm) quartz-Co^ veins strike
130 and dip vertically. A third set of minor tension fractures filled with quartz
lie essentially horizontally. Quartz * carbonate * sheared fragments of foliated
sediments usually less than 5"8 mm thick, constitute a fourth set of veins. These
are directly related to dip slip movements shown by si ickensiding, in the plane of
the azimuth of the borehole, on these vein surfaces. This vein type usually occurs
in fine silty argillites.
95-3-109m - Medium to coarse grained recrystal 1 ized chlorite * minor sericite-al tered
felspathic sandstones flooded by calcite. Some minor disseminated pyrite (less than
Ifc). Medium grained felspathic sandstones occupy 50^ of the interval, and have minor
interbedded silty argillites. A few thin .quartz-carbonate veins of all four sets
mentioned above are present. Veins in the coarse sandstones are "ghost-like". At
98m an oblique or parallel vein suggests the possibility of a fifth, North-South
set not intersected by this N-S oriented drillhole. Bedding parallel, fault dip-slip
veins of less than 8mm occur at 95-3, 98.5, 103.5 m. Some of the thin stratabound
bedding planar, but non-sl.ip, veins have minor skins of pyrite. Sericite is largely
absent from veins and affects none of the sediments except coarse sandstones.

of this style. Some have minor selvages of sericite, but this mineral is only of minor
importance. Alteration . is essentially absent. At 179.5m a 2cm irregular quartz * carbonate
pyrite -*- 5fc sphalerite vein has some sericite microscopic dark grey (Tcarbon) edges.
A similar vein, without sulphides occurs over 176-176. 3™, but lies in a North-South plane.
Other l-2cm veins of quartz-carbonate occur at 157-9m; 163-7; 16?; (176); (179-5); 186.5.
A few 45 -trending, 60 south dipping tension veins in incompetent greywackes are present at
186.5m; 191; and show a comb-structure of quartz-carbonate intergrowths between the walls of
the veins.
Between 191 and 192.5 a north-south vein runs in the plane of the hole azimuth. This
could be a hidden vein set not tested by the drilling.
Between 185 and 197 the argillite units show a change in colour to olive green or khaki,
due to original lithology or alteration - could be sericite alteration, associated with
planar bedding oriented dip slip crush veins.
Foliation fabrics are not clearly evident in this core, due to its dominantly greywacke
character. Carbonate flooding as rhomb i c alteration is essential1y absent except in a
few veins. Sulphides are low in volume. The hole is visually unpromising for gold.

Whole grading into siltstone and then mudstone. Generally massive, except in a few places

GREYWACKE-SILTSTONE/MUDSTONE - several cycles of upward grading generally massive, grey sedimen
tary sequence. Occasional float-up fragment. Quartz-carbonate veins 1 to 3 mm wide mostly
25 to 30 to core axis, also very fine sectional fractures semiparallel to core axis. Some

occasionally contorted. From 105 to 109 a few places pseudobrecciated with quartz cement. At
108.5 graphite flakes in quartz. Bedding faint at 60 /core axis.
GREYWACKE distinctly pale green (as 110.2-114 in GD-02) equigranular, massive, appears
intrusive, but fragments are locally very distinct, calcareous (primary). Also irregular
pale yellow carbonate veins with minor quartz in a few places. Pyrite specks throughout.
Lower contact marked by 2cm's wide quartz carbonate vein with some chlorite and sericite.
GREYWACKE (70S) SILTSTONE/MUDSTONE -very much as 70-111.5. Uphole gradings, fine grained,
greywacke, coarser fraction, calcareous massive. Bedding in siltstone 60 to core axis.
Minor carbonate veining usually at 30CVcA and Ao'VcA. At 130m core broken, some gange - minor
fault. From 142-151 -5m abundant fine carbonate fractures at kS /CA, but also at other angles.
Locally rock in this section has brecciated aspect due to this carbonate veining. Pyrite
blotches and a few veinlets occasionally present.
From 164- 175 'carbonate veining as above but with pyrite blotches locally.
