BHD8	Sock Creek	0	7	PP	pr	90	6	CY	bx	10				Yel	Brn	b	HW	Pale yellow-brown very strongly weathered Quartz-Feldspar Porphyry.  Comprises broken clay rich bleached massive intrusive with abundant quartz and feldspar phenocrysts to 5mm.  Alteration is very weak and obscured by weathering. No veining or mineralisation. Core is incompetent with broken and puggy zones common. Lower contact is transitional into fresher porphyry.
BHD8	Sock Creek	7	20.2	PP	pr	100	6							Gry	Brn	m	SW	Grey brown weakly weathered and oxidised Quartz-Feldspar Porphyry.  Comprises a massive quartz-feldspar (phenocrysts to 5mm) Porphyry intrusive with decreasing oxidation to the base of this interval where only oxidised fractures are present.  Only trace silica alteration obvious. The lithology is not veined or mineralised.  Core competency is good with 5-7 bpm except below 17m where strongly broken core dominates. The lower contact is sharp but smeared by broken puggy core as lith changes into a black shale.
BHD8	Sock Creek	20.2	25	BL	fg	98	2	VC	fg	1	PP	pr	1	Blk	Gry	m	Fr	Dark grey to black weakly bedded Black shale unit.  Comprises broken weakly laminated fine grained black shale with thin (2-5cm ) qtz-feld Porphyry and volcaniclastic siltstone beds. Unaltered unmineralised and not veined.  Core is not competent with blocky fracture throughout this interval. Some puggy shear at 23.8m.  Lower contact is bedded into a paler green volcaniclastic siltstone atop a mass flow unit.
BHD8	Sock Creek	25	75.9	VC	po	95	7	VS	mg	5				Gry	Kh	mo	Fr	Grey to khaki classic graded Mass Flow volcaniclastic unit.  Comprises a complete transition from fine grained sandstone to coarse (+50mm) polymict volcaniclastic breccia at base of interval.  At least 6 compositionally distinctive volcanic and lithic clast types apparent. Matrix is weakly silica altered and the fine grained top 3m of the unit is sericitic. The bottom 15m has weakly chloritic pumice fragments to 1%.  Trace pyrite is evident below approx 60m increasing to 0.5% close to the lower contact. Very minor qtz-carb veins to 10mm increasing lower in the unit. The core is moderately competent with 3-6 bpm except for the top 5m of the interval where the fine grained portion of the mass flow is blocky fractured (>12 bpm). The lower contact is confornmable into a dacitic lava unit.
BHD8	Sock Creek	75.9	107.8	LB	hy	98	7	DA	m	2				Kh	Gry	mo	Fr	Mottled grey-brown Dacitic lava breccia. Comprises uniform 10-20mm autclastic fragments of aphyric dacite in a dacitic matrix. Minor zones to 1.5 m of non-brecciated dacite lava throughout. Alteration is insignificant (trace) sericite+/-silica+/-chlorite. Rare pyrite disseminations and veinlets observed. Rare quartz+/-carb veins to 10mm in lower part of interval.  The core is poorly competent with several zones of broken rock between zones of reasonable competency.  The lower contact is gradual but marked here by a broken and sheared zone.
BHD8	Sock Creek	107.8	138.5	DA	m	80	5	LB	hy	20				Kh	Brn	m	Fr	Massive Dacite lava with lesser zones of lava breccia.  Comprises very weakly altered Dacite lava (aphyric to weakly ?mafic-phyric) with minor zones of lava breccia identical to the previous interval. Alteration is negligble sericite-silica. Trace disseminated pyrite observed. Veining is very minor carb-sil veinlets to 2mm. The core is mostly competent (3-5bpm) with several more broken zones over 1-2m. The lower contact is marked by a change in alteration into a new lava unit.
BHD8	Sock Creek	138.5	158	DA	m	100	4							Kh	Ora	b	Fr	A more coherent massive Dacite lava unit.  Comprises fine to medium grained aphyric to ?hornblende-phyric dacite lava.  Faint perlitic textures and weak autoclastic textures also. Weak silica-pyrite+/- trace Kspar? alteration pervasive throughout (no other sulphides). Minor to common quartz-carbonate+/-chlorite veining.  The core is moderately competent with 5-8 bpm and only minor broken zones. The lower contact is conformable and gradational over 5cm into a more brecciated lava.
BHD8	Sock Creek	158	163.5	LB	hy	98	7	DA	m	2				Oli	Brn	mo	Fr	Another zone of Dacitic Lava Breccia - almost identical to 107.8 to 138.5m. Comprises up to 25mm clasts of hyaloclastic dacite (weakly ?Hbl-phyric) in a dacitic matrix. Relic perltc textures evident in clasts. Alteration is very weak (silica-sericite+/_chlorite).  Rare races of pyrite observed.  1-2mm stringer veinlets of silica-carbonate to 2%.  The core is poorly competent with minor puggy zones and several thin broken sections. The lower contact is marked by such a broken zone which ends in a more massive dacite lava.
BHD8	Sock Creek	163.5	201.1	DA	m	98	4	LB	hy	2				Kh	Ora	m	Fr	A coherent very weakly altered massive Dacite lava.  Comprises fine to medium grained aphyric to perlitic to moderately mafic-phyric dacite lava. Possible amygdoils at top contact and elsewhere through this interval.  Alteration is weak silica+/-sericite+/-Kspar.  Very minor pyrite is disseminated throughout.  Veinlets of silica-pyrite are common.  The core is moderately competent with 4-6 bpm except for the last 9m which are increasingly broken.  The lower contact sudden but obscured by broken core.
BHD8	Sock Creek	201.1	230.4	RD	ph	100	5							Brn	Ora	m	Fr	Brown-grey to orange feldspar-phyric rhyodacite ?lava.  Comprises massive uniformly feldspar-phyric Rhyodacite.  Very minor hyaloclastite textures. Ateration is weak silica-albite often as phenocryst replacement.  Core is not mineralised but has very minor pyrite disseminated throughout.  Veining is rare - usually as thin carbonate-silica stringers.  This section of core has improved competency with 2-4 bpm.  The lower contact is preserved as an intrusive contact of the rhyodacite against a fine grained sediment.
BHD8	Sock Creek	230.4	235.4	BL	br	75	2	ST	cg	20	HY	pe	5	Blk	Brn	d	Fr	Dark grey to brown sedimenary hiatus between volcanic phases.  Comprises disrupted black shale interbedded with coarser siltstone (?volcaniclastic) and minor peperite due to basalt intrusive beneath this interval. The sediments show evidence of baking.  Alteration is variable but weak - mostly silica+/-carbonate+/-sericite.  There is elevated pyrite especially in the coarser more porous units.  Minor sphalerite observed at 232.1m in silica-carbonate veins. Vein density slowly increases through the interval.  The core is poorly competent with variable 3-12 bpm.  The lower contact is obscure - peperitic sediment marks the transition into an amygdoloidal basalt.
BHD8	Sock Creek	235.4	239.9	BS	am	100	5							Gry	Kh	m	Fr	Massive grey basalt ?sill.  Comprises amygdaloidal (to 8mm) to hornblende-feldspar phyric basalt with an upper peperitic contact and a lower ?depositional contact.  Virtually unaltered.  Numerous small carbonate-silica veinlets.  Unmineralised.  Moderately competent with 3-5 bpm.  Lower contact is sudden - marked by a 2-4mm light grey shale unit above a coarser volcaniclastic sandstone unit.
BHD8	Sock Creek	239.9	245.4	ST	mg	80	3	VS	mg	20				Gry		d	Fr	Dark grey sedimentary sequence of interbedded fine to coarse volcaniclastic units.  Comprises interbedded volcaniclastic siltstone and sandstone beds showing occassional grading.  Bedding commonly disrupted.  Unaltered and weakly veined by carbonate-silica stringers plus rare 50mm veins.  Minor to trace pyrite only especially within coarser more porous units.  Core has low competency with minor puggy broken zones throughout.  Lower contact is marked by peperitic contact into a dacitic volcanic.
BHD8	Sock Creek	245.4	250.4	RD	pe	100	7							Gry	Oli	mo	Fr	Mottled dark grey rhyodacitic peperite.  Comprises well developed peperite of rhyodacite in a pale grey siltstone.  Matrix decreases with depth through the interval leaving massive feldspar-phyric rhyodacite.  Weak chlorite alteration appears to pick out the rhyodacite clasts.  The core is not mineralised except for a bleb (20mm) of pyrite at 248.3m.  Minor carbonate-silica veinlets occur throughout.  The core is quite competent with only 3-4 bpm.  The lower contact is gradual and transitional into more massive rhyodacite.
BHD8	Sock Creek	250.4	303.6	RD	m	100	5							Grn	Oli	l	Fr	Light olive to light green-grey massive to feldspar-phyric rhyodacite.  Comprises variable feldspar-phyric rhyodacite ?lava.  Phenocryst % is decreasing down this interval and some weak compositional banding is evident near 275-278m and from 290 to 302m.  Alteration varies slightly over this unit with moderate chlorite staining the core dark green at the start through silica bleaching and into sericite-silica alteration lower in the interval.  Common 1-3mm silica-carbonate veinlets.  No mineralisation observed.  The core is quite competent with 2-4 bpm.  The lower contact is sharp with minor veining increasing in the last 20cm before the contact.
BHD8	Sock Creek	303.6	398.4	BL	fg	80	2	GY	mg	20				Blk	Gry	d	Fr	Black to dark grey interbedded mix of unalered black shale and gritty greywacke.  Comprises mostly black shale with poorly defined bedding interbedded with medium to coarse grained greywacke.  Unit is Animal Creek Greywacke.  No alteration observed. The contact with the Rhyodacite above is sharp - howeve there are two 10 to 20cm thick dacitic intrusions within the shale just below the contact (at 304.3m and 305.5m) showing interfingeing of he volcanic and sediment.  Bedding is consisently at 5-20 degress to core axis (mostly 10-15 degrees).  Trace to minor pyrite observed throughout both as fine disseminations and as coarser blebs to 25mm.  Veinlets of silica-carbonate to 30mm common but decreasing in intensity towards bottom of hole.  The core is reasonable competent with 2-5 bpm but several weakly broken zones disrupt this consistency.  The lower contact is not seen due to end of hole.
