ADHO14.

Drill hole ADH014 encountered a thin layer of boulder terrace at the surface and drilled straight into a felsic diorite unit. Down to a depth of 150m, the hole encountered an extensively brecciated and silicified unit. The breccia displays monolithic to polymictic textures with clasts of diorite only and clasts of diorite and andesite respectively. The diorite clasts are strongly bleached and moderately altered to clay while the andesite clasts a fresh with chlorite +-epidote +- trace pyrites. Most of the clasts are angular and rotated with open spaces partially filled with pyrites . Late stage of pyrite + sericite veinlets cuts through with fine hairline magnetite veins. The weak to moderate pyrite mineralisation on the class may be related to the late phyllic alteration which is overprinted by weak clay alterations.

==> picture [491 x 165] intentionally omitted <==

Polymictic breccia (40m-150m)

This breccia unit appears to be at the top part of an intensely shattered and variably brecciated rock sequence which continues from 150m to half way down the hole. The predominant rock-type within this sequence is a diorite unit (and microdiorite) with some occasional quartz diorite. Small dykes of andesite/basaltic units intrude the above unit. The shearing and shattered event in the breccia is perhaps related to this intrusive activity.

Brecciated bleached rock with late qz-py-sulph [email protected] – 463.30m

Polymictic breccia bands within this unit range from a couple of meters to up to ten meters thick. The rocks appear to have been subjected to strong pervasive silicification with strong qz-ser-py alteration with weak to moderate clay enrichment in the fractures. The silicification appears to have been overprinted by a bleaching event, possibly related to the late andesite and diorite intrusive stages which appear to have given it the vuggy appearance. Some milky white qz-cb? pyrite veining cuts the above units, pyrite is ubiquitous and constitutes up to 3% of the rock.

From halfway down the hole to the end at 1004 m, the down hole geology is dominated by mafic rich rocks. Pyroxene andesite appears to be the dominant host rock, intruded in places by diorites/microdiorite.

The potassic alteration correlates well with the occurrence of weak to trace disseminated chalcopyrite moly mineralisation. Blebs of chalcopyrite were also noted towards the end of the hole. Late vuggy qz-cb sulphide (py-cpy-mo) veins are also common in some parts of the hole and cut through the ubiquitous narrow grey white –quartz-carbonate veins.

In summary, hole ADH014 encounted a thick unit of intensely shattered, silicified and brecciated rocks in the top part of the hole. This structural activity appears to be related to a series of felsic and andesitic dykes which intrude the rocks. From here to the bottom of hole at 1004 m, the hole encounted a rock sequence dominated by pyroxene andesites and basalts but also with wide intrusions of miccrodiorite, diorite and pyroxene rich porphyries. Chlorite-epidote-magnetite and carbonate and pyrite (disseminated) is the dominant alteration aseemblage throughout this hole, with a zone of weak potassic alteration characterised

by biotite-actinolite-chlorite-magnetite developed in the lower portion of the hole. Some clay-sericitechlorite-magnetite enrichment is noted in areas of structural weakness. Hematite blebs are conspicously present througout the hole in less silicified rocks.. Rimmed quartz-carbonate and pyrite veining is ubiquitous and occurs across all lithlogical boundaries. Pyrite, chalcopyrite and molybdenite are the main sulphide minerals present, with pyrite normally occuring as blebs and veins especially wihin vugghy quartz sulphide veins which are normally sub parallel to core axis. Trace disseminated chalcopyrite-molybdenite mineralisation is associated with the potassic phase.

ADH 015

From surface to 300m, hole ADH015 drilled through a pyroxene rich andesitic sequence which was intruded by occasional felsic and mafic dykes. The dykes consisted principally of fine grained equigranular rocks mainly of dioritic and or dacitic composition. They appear to occur within a couple of clay shear zones which were tens of meters thick. Abundant clay-sericite-pyrite-fuchsite development is common within these shear zones. Silicified and brecciated rock fragments containing visible chalcopyrite-molybdenite mineralisation were sampled within these shear or fracture zones. The chalcopyrite-molybdenite occurs as blebs in veins and in mineralised clasts within these brecciated fragments. The dykes are usually light green in colour due to the pervasive epidote alteration throughout this unit.

Chalcopyrite-molybdenite blebs on vein in brecciated clasts within the shear zone.

From 300 m to 700 m the hole encountered a sequence of pyroxene rich andesites with alternating narrow bands of fine grained pyroxene basalts. The rocks appear to have been intruded by wide dykes of microdiorite which are relatively fresh and unaltered compared to the andesitic host. Fine disseminated magnetite is common and moderately pervasive throughout with haematitic (reddish) alteration.

Chlorite + epidote +-pyrite alteration is moderate throughout. Veining is weak to moderately selective throughout with pyrite + quartz +- calcite. Thick quartz-carbonate –sulphide veining is common throughout the pyroxenes andesite unit and veins are usually parallel or sub parallel to core axis.

==> picture [491 x 154] intentionally omitted <==

Quartz-calcite-sulphide vein sunb parallel to core axis at 458m.

This event may be related to the weakly mineralised microdiorite intrusives. Narrow grey white quartzcarbonate veining is quite common within both the pyroxene andesites and the microdiorite suggesting this event postdates the microdiorite intrusive activity. They sometimes form a halo around pyrite veins also suggesting that a pyrite phase may postdate the quartz-carbonate stage.

Pyrite is the main mineralisation mineral throughout and is confined to veins and structures (minor faults) exploiting the pre-existing fractures. Trace moly is associated with pyrite + quartz + sericite vein and confined in the centre of the vein bounded by quartz and pyrite. Also moly presence is noted in moderately sheared and clay altered fractures.

The last 200m of this hole to 850m is dominated by a sequence pyroxene andesites and basalts with lesser microdiorites. These rocks have been subjected moderately pervasive chlorite-epidote-carbonate-magnetite alteration with abundant narrow quartz-carbonate stockwrking.Weak to trace chalcopyrite mineralisation is

noted towards the end of the hole as blebs usually in quartz-cab-sulph veins.These veins are generally parallel to core axis.

In summary, weak to trace chalcopyrite-molybdenite mineralisation is observed in most parts of this hole especially from 200-500m and thence from 700m down to the end of the hole. It usually occurs as blebs, associated with quartz sulphide veins and in fragments within clay-sericite-pyrite enriched shear or fracture zones. The middle part of this hole is dominated by relatively fresh weakly mineralised microdiorites. The dominant alteration assemblage throughout the hole is propylitic (epidote-chlorite-magnetite-carbonate and pyrite).
