PURPOSE AND METHOD OF 1990 SURVEY
The purpose of the 1990 Brief Geological Survey of the Haggard and
Ayesha Claims Area was t o t r y t o shed more l i g h t on a few par t i cu la r
geological queries encountered during and a f t e r the 1989 survey (discussed
in the 1990 Assessment Report, c f . pp. 11 -1 5 ) .
The megascopic descript ions i n the 1990 Assessment Report and previously
in the 1979 Assessment Report by R . R. Culbert were mainly f i e l d descript ions.
In the present study the typical rocks were sampled, th in sections were cu t ,
and a careful petrographic study of these rocks from the l o c a l i t i e s shown on
Map I by A . Skupinski followed.
Samples of the following rock types were collected: ( see Map I )
Basement: Granodiori t e ;
Quartzi te ( ? ) Breccia of 1990 Report referred t o as "Enigmatic Breccia" by R. R. Cul bert (1 979 Report) ;
Springbrook Conglomerate (1 990 Report) ;
White Tuffaceous Sandstone (1 990 Report) ;
Dacite of the lowermost Yellow Lake Member sequence ( R . R . Cul bert 1979);
A few gold assays of rock chips collected were a l so done. However, the
primary purpose of the present survey was t o f ind the t rue petrography of the
rocks 1 i s t ed in order t o eventually t r ace t h e i r possible gold prospects in
the f i e l d .

MIDDLE EOCENE - MARRON FORMATION
YELLOW LAKE MEMBER
The Marron Formation of the area was described in f a i r detail by
G . D. Nordin (1978). The Yellow Lake Member i n the Haggard and Ayesha Claims
area consists in the south predominantly of Phonolite and minor Ash beds and
c las t ics ; and in the northern area Tephrites predominate.
The Questionable Daci t e (?)
R. R . Cul bert with R. J . Beaty (1979) identified a sequence of lava flows
in the Yellow Lake Member in the northeastern map area. The lowermost flow
was referred to as Dacite. This rock forms extensive outcrops to the east
and southeast of Brent Lake. I t i s uniform in appearance, l i gh t grey,
grading to reddish further south, f inely crystal l ine, and dense lava, with
d is t inc t , scattered black el ongated basal t i c Hornblende and Pyroxene
crystals , and with l e s s frequent phenocrysts of felspathic crystals and grains.
This rock forms steep c l i f f s and platy scree.
In hand specimen th i s rock could be mistaken for a Dacite. However Dacite
lavas are not usually present in the Yellow Lake Member. Therefore two thin
sections were made of th i s rock from loca l i t i e s DAC and SB1 and petrographic
descriptions are on pages P7 and P8. The petrography indicates that the rock
i s Tephri t e grading to Nephel ine Basalt. These 1 i thologies are in general
agreement w i t h the remaining basic l i thologies of the Yellow Lake Member.
KITLEY LAKE AND YOUNGER MEMBERS OF THE MARRON FORMATION
The younger members of the Marrow Formation, i .e. Kitley Lake member
and younger, were described by B. N . Church (1 973 & 1982). Please see Table
of Formations on p. 8. The basalts on the eastern side of the Marron Valley
Fault are probably of younger Marron age.

MARAMA FORMATION
Four consecutive Andesite lava flows overlie the Yellow Lake member of
the Marron Formation in the northeastern corner of the map area. These rocks
are assigned on our Map I to the Marama Formation according to the map by
B. N. Church (1982). Otherwise these Andesites - defini te ly younger than
Yellow Lake - m i g h t have been considered to be possibly s t i l l of Marron age.
** The rocks are commonly shattered and cut by numerous thin Chalcedony and
Quartz vein1 e t s ( t o date go1 d assays were inconclusive) .
INTRUSIONS
ANDES ITE DYKES
A dyke of reddish brown, dense, hard and heavy rock shot with quartz was
observed, intruding the pre-Tertiary grani te a t l oca l i t y 1-5. A grey Fe l s i t e
dyke continues south-south-westerly from the Astro 45 Claim into the northern
Sukasu Claim area a t l o c a l i t i e s F2-5 and S11. The l i tho log ies and weathering
habits of the two dykes d i f f e r s ign i f ican t ly . Both dykes are Andesite and
both s t r i k e in a north-northeasterly di rect ion. Undoubtedly other dykes are
present in the map area but have not been investigated t o date.
** Assays of the Andesite from local i t y 1-5 yielded abnormally high quan t i t i es
of 1 ead (3077 pprn) , 3.4 ppm of s i 1 ver and 103 ppb of go1 d during the 1989
survey.

SPECULATIVE COMMENTS
12 'thin sections represent three genetically different groups of rocks: plutonic basement, mainly . granitic and granodioritic with some contribution of the hornfelses; rhyolites; and foidal basalts.
The rhyolitic rocks (including rhyodacites) are genetically related to the basement and result from basement remelting. Common relics of not completely remelted plutonics and hornfelses, and also mineral components of basement material e.g. paleocrystals of microcline, are abundant within rhyolites. Foidal basalts undersaturated with silica, represent a completely independent stage of the volcanic activity within this area.
From the point of view of gold economies, the best prospects appear to be primarily in rhyolitic volcanics.The chance of gold mineralization is best within the porous and tuffaceous representatives of that family. The alteration processes and intensive siderite carbonatization of the tuffogenic varieties of the rhyolites are excellent indicators of the possible gold mineralization in the area. Siderite seems to be the pr'oduct of the post rhyolitic hydrothermal activity and was found also in feldspathized hornfelses.
The problem of the hornfelses within this area is not fully resolved. The samples: 116, 17m and 2 were described as hornfelses only on the basis of the typical sieve texture. The lack of typomorphic minerals e.g. cordierite, pyroxene could. result from the intensive fcldspathization very close to the contact with the granitic intrusion.
The most probable sequence of events within investigated area could be as follow:
1. Granitoid intrusion changes preexisting pelitic rocks to hornfelses. Further metasomathosis is responsible for their intensive microclinization.
2. Increasing temperature within the area is producing the rhyolitic lavas in the deeper parts of the basement. Rhyolites are products of the remelting bcth: granitoids and hornfelses. New lava is intensively rejected toward the shallower horizons through the tectonical discontinuities (faults, shearing zones ? ) . Energetic movement of rhyolitic lavas results in strong brecciation of their minerals.
3. Hy.drotherma1 sideritization ends the rhyolitic stage of the volcanic activity.
4. The younger volcanics within the investigated circa are mainly undersaturated with silica nephelinic basalts and tephrites. The andesitic sequence in the northeast is youngest.
5. The relation of the andesitic dyke 1-5 to the rhyolites and the andesitic seguence is not clear at present.

This desktop evaluation of data from the Ostro 45 claim is carried out at the request of Petro-Canada Resources. The review includes nork carried out by INCO at the VCKhT property, data recently gathered by Uhiterabbit Resources Ltd. and Lossan Explorations Ltd, and relies on the writer's personal experience in the area.
This report suggests that the 'pink grit. (Church, 1984; See Figure No. 3) cored by Petro-Canada's DDH 78-5 is equivalent to the bottom unit found at the VCWLT property near Kaleden, where INCO Gold and partner Seven Wile High Resources Ltd. have defined an epithemal gold deposit with a resourea potential in the Central Zone of 1.342 million tonnes of 2 grams Flu/t, a mineral resource of 150,000 tonms of 14 grams Ru/t in the North Zone a d an undisclosed resource of grade similar to the Central Zone on the West Zone.
In the Farleigh Lake and Brent Lake areas, the 'pink grit* unit, the underlying* Rhyolite Complex found at the bottom of DDH 78-5 and Churchss Felsic Intrusions (See Figure No. 3) are all linked a d included in the Lomr Uaraaa Formation, These units are reported laltercd and minbralized ,by Whitcrabbit, who describes the hydrothermal alteration at Farleigh Lake as ". .. infillings of calcite, ankerite, zeolite, chaleedony and chlorite with several grab samples assaying fr# 70 to 103 and 280 ppb gold and up to 2.3 ppm Rg.,,* associated to a soil gold anomaly, Rt Brent Lake, chloritization, impregnation of matrix by Fe-oxides, and propyl it ic alterat ion of plagioclases are p-nt,,,", Their geochemical analysis of grab samples fwrr the area rhous highs of 3,077 ppr Pb and 3.4 ppm fin. Other assays reported by Uhiterabbit indicattr that this zone of hydrothermal alteration may indeed covcr a large portion of the CIItro 45 and Urnlopogaas claims.
Ue strongly recommend that m exploration prepraw consisting of r ~ ~ ~ n n a i s u n e m prospecting, soil and rock sampling and geolopical mapping be carrid out in the Farleiph Lake - Brent Lake arras, Should the peological model be confirmed and shonings with cscomrmically significant assays be foud, a program including trenching, griddd suweying <soil sampling, magnetometer, geological mapping) and diamond or rotary drilling would follow,

INTRODUCTION
This report reviews and updates reports on the Flstro 45 claim written on behalf of Whiterabbit Resources Ltd. (Whiterabbit") and Lwsan Exploration Ltd. (*Lossan"). Fllso reviewed is information released by Seven Mile High Resources Ltd- and INCCl GOLD f r o m the nearby VCWLT property. The report uas commissioned by Mr. David C, Kinton of Petro-Canada.
PROPERTY DESCRIPTION *.
The ClSTRO 45 claim (Record No. 257, 19 units, in good standing until March 9, 1993) is owned by Petro-Canada Resources and is under option to Whiterabbit. Details of title mre updated by Mr. David C. Kinton, Regional Landman, Western Canada Exploration, Petro-Canada. See Figures No, 1 and 2.
The Chtro 45 claim is located about 11 kilometres nwt of Pcnticton, B,C. The claim is acccsrible by paved road to Farleiqh Lake, then by logging roads which traverse the north and south portions of the claim.
PREVIOUS EXPLORRTION
Virtually no exploration or prospectin4 was carried out on the property until the uranium rush days of the late 197OVs, Xort of the White Lake Basin, including this around, uar proteetad with the M T R O claims during Petro-CarmdaBr search for uranium- The claim a m clammed as DESIMTED URCINIUM B R O W under the uven year Uranium Uoratoriua, Sin- the terminat ion of the Uorrtoriun in February of 1987, all exploration on claims so clasrified is g w . r m c d by the Exploration Reflulation - Uranium and Thorium (Order in Council No, 335) w e n if such work is directed towards prrcious metals,
The claims protect a similar geological environment eo the Vault property of Seven Mile High Reimurcer Ltd. and operator INCO 6dd, Recent reports indicate that the partners have defimd three mineralized zones. They ares

and 3. The West Zone, which is reported to contain .,.9higher grade zones similar to those indicated in the Central Zone but at depths less than 100 a.
Whiterabbit has incorporated the FISTRO 45 claim within its H6IGWlRI) GROUP OF CLCIIMS, with a total of 113 units, which also includes its Brent Lake showing. Since optioninp the claim, Whiterabbit has carried out preliminary detailed reconnaissance and minor soil, rock, water, grasr/aoss sawpling and thin section petrographic studies in the area.
The Basin has been geologically mapped by D, Tempelman-Kluit (1989) of the Geological Survey of Canada and by B. N. Church (1973, 1980, 1984) of the B,C. Geological Suwey, The former carried out regional geological mapping of Tertiary rocks whereas Churdr9s work was restricted to the Basin and, thus, is more detailed,
The CIstro 45 claim lies along the northwestern wargin of the White Lake Basin, mich is a strongly block-faulted and deep Successor Basin. The estimated preserved thickness of Eocene volcanic and sedimentary roeks within the basin is of wore than 3,600. metres.
Church (1984) describes the geological setting (Sea Figure No, 3) of this area as *,,, underlain by an eroded Jurassic- Cretaceous granitic complex that is partly rovarcd by basal Tertiary volcanic and sedimentary r#zks, Tho Kettle River Formation is the oldest Tertiary unit and consists of granite boulder conglmrate, ark-, and rhyolite tuff that unconformably overlies the granite, Disconformably above this are purple and grcy volcanic wckr, wackes a d siltstones of the Yellow Lake Member of the WIrron Formation, Thwe units are succeeded upwards by slightly younger trachytes of the Nirpit Lakc h b e r of the Marron Formation and dacitic lavas and feeder dykes of the Mar- Format ion,, , *,
The k r m n Valley fault slices north-mwthnesterly through tho eastern portions of the claim, The Tertiary beds are gently inclined to the south and southwest,

Two rtructurally controlled epithrrrmal gold deposits are known within the Basin, They are the Vault and the Dusty Mac- R showing at Brent Lake, located iwmediately north of this property
and within Uhiterabbitls property holdings in this area, displays the same characteristics, strong hydrothermal alteration and weak Ru-Rg-Pb mineralization,
DISCUSSION
Groeneweg & Hunter (Cksessr#ent Report # 15,535) described the bottom of the Eocene stratigraphy at Incols WULT property as followsr
+ 'The Hamon F m t i m (hit 1) is rude up of extensive flom of porphyritic trrchyte consistiq of up to 70% of fine k-spar laths and up to 30% lugc tabular phenonyrts of k-spar to 3 r in size. Minor constituents of the t ~ & y t c m quartz, heutitc, dolaritc, scricitc and clay resulting fnm alteratim ud silicification. The top of the trrhytc appears to k m t h m d and is consided to k an m#iaul surface.'
Church (19841 deserihes a SO metre thickness of beds of 'pink gritv in Petro-Canada9s DDH 78-5 as followsr
'They ocwr below the lowest rrfic phonolite lwas of the Yellow Lake llerkr ud onrlic tuffamus sandstom ud siltstonca The grit is well layered, however, it displays few exvples of grading, mKcbeddiq or scour structures. The ink m l m of this rock iq paused bv mrmwr broken rlkali-fclds~rr ms ta l s md uebbles of f c l b t h i c rhab wc'lll)Lm
Hm the grit is lostly eroded several tuffxwus laym ud r few my thin coal rserrs, 1 t o 3 u t h i c k , mapomd.'
These two units are essentially the saaae, Thm possibility that the 'phk grit* unit at Farleigh Lake was deposited along a creek channel or topographic depression is suggested by Wro- Canada9s 1979 work and by Churrh (1984), In this interpretation, ChurehVs 'pink grit9 unit, the underlying Rhyolite Complex found at the bottom of D m 76-5 and Church,s Fclsic Intrusions (Sem Figure No, 3) arm included in the Lower H a r m Foraation volcanic (and intrusive) went and would correlate geologically to the baseaumt of mineralization at the WKlLT property, as described by Braenamp & Hunter,
Whiterabbit describes tho hydrothermal alteration at Farleiah Lake as . i f l i n g of calcite, ankerite, zcolitc, chalemdony and chlorite with several prab samples assaying f r o m 70 to 103 and 280 ppb pold and up to 2-3 ppm Clg-. ,, associated to a roil gold anomaly,
Whiterabbit also describes the showing at Brent Lake as #I ,,,cut by abundant (although thin) cryrtallina quartz and
chalcedony veins- Intensive chlorit izat ion, impregnat ion of matrix by Fe-oxidn, and propylitic alteration of plagioclaws arm present,-, '- Their goochmicrl analysis of grab samples from the area shows highs of 3,077 ppr Pb a d 3-4 ppm fig. Other assays reported by Whiterabbit indicates that this zone of hydrothnral alterat ion may indrrd cover a large port ion of the Chtro 45 and

Umslopogaas claims.
CONCLUSIONS & RECOMMENDClTIONS
High geochemical backgrounds of Pb, g and Cu in rock samples collected by Whiterabbit appear to be associated with +I00 ppb gold analyses in rocks described to have crystalline quartz, chalcedony veins, intensive chloritization, strong Fe- oxides, and propylitic alteration of plagioclases. These rocks are found in the north-central portion of claim Rstro 45 and portions of the adjacent Umslopogaas claim. This environment is favourably compared to that found at the VFWJLT property. Systematic exploration and prospecting of these areas nith a Vault type of target in mind has yet to be carried out.
We strongly r-nd that an exploration prograw consist ing of reconnaissance prospecting, soil and rock sampling and geological mapping k carried out in the Farlcigh Lake - Brent Lake areas. Should thm geoloqical model be confirmed and showings nith cconowically sigdificant assays be found, a program including trenching, pridded surveying (rsoi 1 sawpling, magnetometer, geological mapping) and diamond or rotary drilling would follow.
