INTRODUCTION
The author and O stowell prospected the Pine and Woods
Claims August 11 and 12 1987 and the author returned to the
claims on April 27 1988 via helicopter to gather additional
information Traverses were plotted by means of compass and
pace survey Detailed measurements in the vicinity of the main
showings were made with a survey tape Traverses were designed
to cross anomalous areas indicated by an earlier regional survey
o
Samples were collected on both trips to the property
Sections were cut from these and observed under 40x magnification
with the aid of a microscope Measurements of grain sizes were
made utilizing the scale built into the microscope An unusual
silver mineral was observed in one of the samples The sample
was sent to Vancouver Petrographics for further study where two
sections were made of the sample Their report is included in
Appendix B All samples were examined under ultra violet
lightThe property was also visited by representatives of
MineQuest Explorations in November 1987 who consented to the the
use of their sample results in the submission of this report
The helicopter provided a bird s eye view of the property
to give a better idea of the structures present on the property
and to locate other gossanous showings While weather conditions
did not permit landing on any of the sites observed their
locations were recorded and elevations determined by hovering at
eye level with the showings and determining the elevation by
means of the helicopter altimeter Photographs of these showings
are contained in Appendix A to this report
LOCATION AND ACCESS
The Pine Woods claims are located 257 km west of Williams
Lake B C and 16 km southwesterly from Kleena Kleene B C on the
Klinaklini River Figure 1 The Claims are accessable via the
Bella Coola Highway to Kleena Kleene and from there a four by
four forestry access road leads to the claims A spur road leads
to the main showings on the property The forest access road
runs along the southern margin of the Woods claims The property
is located in a sandy soiled pine forest between the elevations
of 820 and 1400 m The claims are located on the margin of the
coast plutonic complex where it comes in contact with the Nechako
Plateau

They are currently held by O stowell and S Fadenrecht
as a group under private agreement between the parties All
claims h ve been staked on the two post system Figure 2
HISTORY
The property was found by Mr Woods while searching for
the source of substances which had made his horses sick from
drinking the water The claims were privately held until their
option to Cadillac Explorations and McLeod Copper in 1973 when
three diamond drill holes were completed in the vicinity of the
main shdwing The ground was mapped by Asarco in 1975 and a
geochemLcal survey was conducted but never recorded for
assessm nt In 1979 the ground was staked by Mr Stowell and
subsequ ntly optioned to Rhyolite Resources Inc who conducted a
regional geochemical program staked additional ground and
conducted a follow up geochemical program The ground was
allowed to lapse Mr Stowell restaked the main showing in 1985
and S Fadenrecht staked the adjacent Woods Claims in 1987
REGIONA GEOLOGY
o Inclusions of altered sediments and volcanics occur in
granitic to dioritic terrain in the immediate vicinity of the
property To the northeast of the property the dominent
lithologY appears to be an andesitic lapilli Tuff with clasts up
to 15cm in diameter In places the tuff has been hydrothermally
altered to a serecitic assemblage The tuff appears to be in
fault oontact with granitic rocks to the southwest Taylor Creek
Group shales siltstones and greywackes are reported to occur on
the banks of the Klinaklini River
Northeast Southwest and North South striking faults cut
through the property and are splay faults to the main Tchaikasan
faultThe Perkins Peak Gold Prospect of Kleena Kleene Gold
Mines lies 19 km southeast of the main showing
PROPERTY GEOLOGY
Hornfels metasedimentary volcanic roof pendants occur
within an intrusive complex of dioritic to granodioritic
composition Figure 3 The pendants are commonly grey and
brown fine grained volcanic sand or siltstones Variability in
composition results in alternate color banding 2 mm thick
Outcrops are generally small and appear more as subcrop There
does notappear to be any sulfide associated with the hornfels

o
The predominent lithology present on the property is a
dioritic to granodiorite intrusive Several phases of intrusion
are present The dominent phase appears to be a grey to white
hornblende diorite In places the hornblende is partiallyaltered to chlorite In some phases minor biotite is also
present in the matrix The percentage of quartz in the matrix is
variable upto 5 Quartz eyes approximately 5 em in diameter
may also be seen in some samples The intrusive forms well
rounded outcrops which are sparsely vegetated It weathers to
form a sandy soil in most places although in the western portionsof the Woods claims the intrusive appears to be more silicified
and forms resistant ridges which are especially dominent when
observed from the air Trace pyrite is present in the matrix in
areas away from the main showing In the vicinity of the main
showing trace amounts of disseminated chalcopyrite arsenopyriteand sphalerite are visible
At the main showing it appears as if three different
dioritic phases occur Massive arsenopyrite occurs near or at a
dark grey black microdioritic to andesitic dyke which has been
interpret d by some geologists as hornfels mafics Microscopicexamination however indicates a primary origin See Appendix B
XINERAL I ZATION
o
Gold and silver mineralization occurs with arsenopyritein subhor zonal fissure viens cutting the microdiorite The five
most significant viens each average 15 em thick but locally may
swell upto 40 em The veins are undulating and appear to occur
along structural breaks There are reports of similar viening in
the hornfels Faulting is evident in the area of mineralization
An assemblage of galena sphalerite arsenopyrite chalcopyriteargentite pyrite and pyrrhotite is present in the fracture
fillings The dominent sufide appears to be arsenopyrite which
is a silver grey in color There also appears to be a largepercentag of pyrrhotite in the matrix although it is hard to
differentiate from the arsenopy rite as it has only a slightbronze tinge to it The presence of pyrrhotite is best detected
through its magentic affinity Only trace amounts of chalcopyriteappear to be present in the mineralization at the main showingThese app ar as small isolated blebs within the the sulfide mass
or on the margins of fracture viens Chalcopyrite does however
appear to be one of the trace minerals associated with higharsenic gold values from the work done in the previous RhyoliteResources survey
Another significant trace mineral indicated by the
Rhyolite survey is elevated values of bismuth A petrographicstudy on sample 87M2L is included in Appendix B It identifies
possible bismuth tellurides as being presentThe petrographic study conducted by Vancouver
Petrographics also reported the presence of fine grains of free
gold within the arsenopyriteSample MS 02 88 showed an elevated value 19 ppm in
Scandium which is anomalous Scandium has recently been the

CONCLUSIONS
While the lenses of sulfide at the main showing are
discontinuous and small within themselves their abundance and
good gold values may lead to a bulk tonnage target The deposit
appears to be structurally controlled and oriented in a
north south direction Interpretation of the data gathered
previously by Rhyolite Resources along with the gossanous areas
detected on during the course of this survey indicate the
potential for other mineralized zones parrellel to the main

in locatiqn of other showingsA strong structural fabric is evident from the air as
shown in the photographs in Appendix A The terrain appears to
have been ifaulted in at least two dominent directions which makes
correlation of the existing showings difficult without further
detailed surface work These structures may be the source of
silicific tion observed in some of the outcropThis survey did determine that the property merits
continued exploration Within its limited scope no new showingswere located on the surface A much more detailed survey is

The host rock is dominated by very fine grained quartz intergrownwith patches of extremely fine to locally very fine grained sericite
Locally quartz forms fine to medium grained patches mainly adjacentto arsenopyrite These arsenopyrite grains commonly have euhedral
terminations against quartz Chlorite forms ragged flakes and patchesaveraging 0 2 0 5 mm in size It is light greyish green in color
Associated with many chlorite patches are patches of extremely fine
grained Ti oxide
Arsenopyrite forms very fine to medium grained aggregates It is
brecciated very strongly along one side of the sample locallychalcopyrite and pyrite occur in fractures up to 0 01 mm wide in these
brecciated zones
Chalcopyrite also forms a very few lensy inclusions up to 0 06 rom

associated with arsenopyrite It is moderately soft light grey with
a low reflectivity and moderate anisotropism with a distinctive blue
color It has one good cleavage and is altered slightly along this
and moderately along grain borders to secondary high relief minerals
It may be stibnite or a more complicated sulfo salt of bismuth or
leadIn Sample lB native gold occurs in a few patches enclosed in
arsenopyrite one grain 0 05 mm long occurs interstitial to very fine
grained submosaic arsenopyrite A few occur in a cluster of
irregular grains averaging 0 005 0 02 mm in size enclosed in a medium
grain of arsenopyrite Associated with native gold in this cluster
are a very few grains averaging 0 005 mm in size of two phases one
cream colored and one grey colored these may be Bi tellurides
Another cluster up to 0 15 mm long of inclusions in a coarse
arsenopyrite grain consists of three or four phases including two
minerals which may be Bi and or Ag tellurides and minor native gold
Grain size averages 0 005 0 02 mm One phase forms a few grains from

chalcopyrite are also apparent as are occasional grains of red brown
resinous sphalerite A bright silvery mineral was also observed but
unidentified
A fine grained metallic steel blue sulfide which formed rods
in a semi radiating texture were also observed associated with mafic
clots In some places these give the sample a feather like texture
where they were associated with quartzA single trace grain of apatite was observed
o ULTRAVIOLET LIGHT
There were no ultraviolet reactive minerals present in this
sample when exposed to ultraviolet radiation

oSAMPLE MS 03 88
LOCATION 30 ro down stream from 87M1L at creek level near vertical
fault gouge zone Out crop in creek weathers to a bright orange and
brown gossanous colour
HANDSAMPLE DESCRIPTION Mottled white and grey black equigranulardiorite with upto 2 mafics CDntains up tD 3 sulfides disseminated
as clDts The matrix has been stained Drange by the DxidatiDn Df
sulfides In places it is cut by hairline fractures which have been
annealed with sulfides The sample is strDngly magnetic
CUT SECTION This sample cDntains very fine grained sulfides of which
arsenopyrite makes up 1 and the remaining 2 is cDmposed of lightbronze to grey bronze cD1Dred pyrrhDtite fDrmed in irregular masses
and clots The pyrrhotite is magnetic Associated with it is a fine
grained cubic black sulfide mineral which may be tetrahedrite Dr
tennantite The sulfides tend tD be associated with mDre mafic rich
areas of the sample Crystal size is generally 1 rom in diameter
Fractures are 1 2 rom wide and have been generally fi ed with
quartz and sulfide minerals giving the fracture a vuggy appearanceTrace stibnite Dccures in the fractures 5 pyrite Dccures
as a bright yellDw sulfide generally associated with fractures as does
traces of galenaTrace fine grained hDney tD brown resinous sphalerite Dccurs
as disseminations and in fractures
o A dendritic bright silver metalic mineral as sketched below
was seen tD occur in this sample and may be a silver mineral
The sulfides appear tD follow lineatiDns and are assDciated
with more mafic bands in the matrix The sample appears tD have been
fractured and annealed in at least two directiDns The mDst prDminentfractures intersect at 20 degrees to each Dther
ULTRAVIOLET LIGHT
No UltraviDlet reactive minerals were nDted when this samplewas submitted tD ultraviDlet light

oSAMPLE 87112L
LOCATION Main showing 10 ft above creek level and 5 ft verticallyabove DDH 3 on a narrow arsenopyrite showing up to 10 em thick Grab
sample from subhorizontal upper vein
HANDSAMPLE DESCRIPTION Massive arsenopyrite with up to 2 quartzoccuring as fracture filings Sample has the appearance of crushed
and fractured crystal mush Sulfides weather to a light buff brown
color band with in fine grained diorite which weathers to cream brown
in color Sample is weakly magnetic in spots
o
CUT SECTION Predominently arsenopyrite composed of ragged crystalsup to 2 mm in diameter Crystals show signs of having been fractured
prior to healing with quartz Arsenopyrite is barely distinquishablefrom pyrrhotite which has a faint bronze coloration to it There
appears to be up to 2 pyrrhotite contained within the arsenopyritematrix Pits are observable in the arsenopyrite grains and may
indicate inclusions Possible very fine grain of gold observable
Sample also contains a trace grey black metallic cubic to
rectangular crystals The sulfide is very fine grained lmm diameter
and occurs in hairline frac ures cutting the arsenopyriteTrace to 1 stibnite randomly dispersed or occuring in small
clots or aggregatesTrace chalcopyrite lmm diameter as discrete grains
Quartz forms 3 of the matrix It also occurs as crystalsalong fractures and results in a vuggy texture The translucent
euhedral crystals are up to l 3mm in length and 1 mm in dia eter
ULTRAVIOLET LIGHT
No ultraviolet reactive minerals were noted when this samplewas submitted to ultraviolet light

Appendix B B 7
oSAMPLE MS 04 88
LOCATION Arsenopyrite float from creek at main showing
HANDSAMPLE DESCRIPTION Arsenopyrite containing a framboidal silverymineral associated with pistachio green alteration mineral Sampleappears to have formed as a frothy crystal mush Contains crystalsof quartz up to 1 cm in length and 4cm in diameter The crystalsare subeuhedral and milky white in color The arsenopyrite crystalsalso appear elongated subparrallel to the long dimension of the
quartzThe sulfide crystals are fractured and have been annealed with
quartz
SAMPLE FMS 01 88
LOCATION from creek at main showing
HANDSAMPLE DESCRIPTION Dark grey to black microdiorite in contact
with quartz viening contain ng irregular blebs of pyrrhotite upto 1 cm
in diameter The pyrrhotite is distinquishable from the blebs of
arsenopyrite also present in the sample by its strong magnetism faint
bronze color and slightly larger masses
The microdiorite itself is moderately magnetic
o CUT SECTION Fine grained 1mm equigranular groundmass composed of
approximately 3 quartz 5 serecite up to 15 hornblende 70 dark
blue grey to grey feldspars
Sulfides are variably distributed within the groundmass and
make up approximately 5 of it The dominent sulfides appear to be
pyrrhotite and minor pyrite Sulfides are more prevalent near openvugs or fractures and are associated with quartz as fillings A steel
blue grey sulfide was seen to occur with bronze pyrrhotite Because
of the extremely fine grained nature of the sulfide it is impossibleto identify at this magnification
The sample also contins a trace amount of brown resinous
sphalerite concentrated mainly along the quartz microdiorite
contact
