Joint Venture Proposal Galore Creek British Columbia Jan E. Christof fersen, P. Eng. Q £ 1 7 7 C. President U U U J J Pass Lake Resources Ltd. 1.0 INTRODUCTION Pass Lake Resources has assembled a large claim holding (101.5 sq. km. or 39.2 sq. mi.) in the emerging Galore Creek gold camp i n north western British Columbia (Fig 1). The Company believes that Galore Creek has the potential to host economic precious-metal deposits equivalent to the high-grade Delaware and Skyline vein-type orebodies just 50 km (30 miles) to the south. This proposal constitutes an invitation for an incoming party to participate in the early exploration phase of certain claim blocks held 100% by Pass Lake. 2.0 REGIONAL SETTING Galore Creek lies in the centre of British Columbia's most exciting gold belt, which extends at least 300 km (180 miles) from the Stewart camp in the south to the Golden Bear mine in the north (Fig 2). Major developing mines in the belt include Silbak-Premier (Westmin), Sulphurets (Newhawk - Granduc), Doc (Echo Bay - Magna Ventures), Reg (Skyline), Snip (Cominco - Delaware) and Golden Bear (Chevron - North American Metals). Total contained gold in these deposits exceeds five million ounces based on known ore reserves. Several other promising silver-gold properties are at various stages of exploration. Most of the deposits occur in an Upper Triassic volcano-sedimentary assemblage along the eastern flank of the Coast Crystalline Complex, which comprises plutonic rocks of Upper Triassic to Tertiary age. Several of the vein gold deposits are spatially related to Upper Triassic alkalic intrusions (syenite, monzonite, diorite). A genetic relationship is also stongly suspected. 2.1 Gold Deposit Types Four types of deposits are recognized within the belt, porphyry gold-copper, volcanogenic massive sulphides (Cu-Au, Cu-Pb-Zn-Au), vein/shear replacement (Au-Ag-base metals) and skarns (Cu-Au-Ag).

1.0 INTRODUCTION Pass Lake Resources has assembled a l a r g e c l a i m h o l d i n g (101.5 sq. km. or 39.2 sq. mi.) i n the emerging Galore Creek gold camp i n north western B r i t i s h Columbia ( F i g 1). The Company b e l i e v e s t h a t Galore Creek has the p o t e n t i a l t o host economic precious-metal deposits equivalent t o the high-grade Delaware and S k y l i n e vein-type orebodies j u s t 50 km (30 miles) t o the south. This proposal c o n s t i t u t e s an i n v i t a t i o n f o r an incoming p a r t y t o p a r t i c i p a t e i n the e a r l y e x p l o r a t i o n phase of c e r t a i n c l a i m blocks h e l d 100% by Pass Lake. 2.0 REGIONAL SETTING Galore Creek l i e s i n the centre of B r i t i s h Columbia's most e x c i t i n g gold b e l t , which extends at l e a s t 300 km (180 miles) from the Stewart camp i n the south t o the Golden Bear mine i n the north ( F i g 2). Major developing mines i n the b e l t i n c l u d e Silbak-Premier (Westmin), Sulphurets (Newhawk - Granduc), Doc (Echo Bay - Magna Ventures), Reg ( S k y l i n e ) , Snip (Cominco - Delaware) and Golden Bear (Chevron - North American M e t a l s ) . T o t a l contained g o l d i n these d e p o s i t s exceeds f i v e m i l l i o n ounces based on known ore reserves. Several other promising s i l v e r - g o l d p r o p e r t i e s are a t v a r i o u s stages of e x p l o r a t i o n . Most of the d e p o s i t s occur i n an Upper T r i a s s i c volcano-sedimentary assemblage along the eastern f l a n k of the Coast C r y s t a l l i n e Complex, which comprises p l u t o n i c rocks of Upper T r i a s s i c t o T e r t i a r y age. Several of the v e i n gold deposits are s p a t i a l l y r e l a t e d t o Upper T r i a s s i c a l k a l i c i n t r u s i o n s ( s y e n i t e , monzonite, d i o r i t e ) . A genetic r e l a t i o n s h i p i s a l s o s t o n g l y suspected. 2.1 Gold Deposit Types Four types of de p o s i t s are recognized w i t h i n the b e l t , porphyry gold-copper, volcanogenic massive sulphides (Cu-Au, Cu-Pb-Zn-Au), vein/shear replacement (Au-Ag-base metals) and skarns (Cu-Au-Ag). (1) Porphyry Gold-Copper

These l a r g e low-grade deposits are t y p i f i e d by the Galore Creek gold-copper body owned by S t i k i n e Copper (Kennco - 60%, Hudson Bay

Page 2: Joint Ventur Proposae l - propertyfile.gov.bc.ca

Mining and Smelting - 35%, Cominco - 5%). This deposit alone contains 125 m i l l i o n tons grading 1.08% copper and 0.012 ounces/ton gol d , equivalent t o 1.5 m i l l i o n ounces of gold. Higher-grade gold s e c t i o n s ( l e . up t o 0.10 ounce/ton) are b e l i e v e d t o e x i s t w i t h i n the much l a r g e r low-grade body. The r e c e n t l y announced discovery of Western Canadian Mining at Sulphurets (66 m i l l i o n tons of 0.84% copper and 0.01 ounces/ton gold) i s another good example. Both of these and s e v e r a l sm a l l e r porphyry prospects ( i e TREK) alona; the b e l t are c h a r a c t e r i z e d by t h e i r a l k a l i c - s u i t e a f f i n i t i e s - s y e n i t e , monzonite porphyries. These a l k a l i c i n t r u s i o n s are b e l i e v e d t o be subvolcanic e q u i v a l e n t s of the Upper T r i a s s i c v o l c a n i c assemblage i n which they occur. (2) Volcanogenic Massive Sulphides

The importance of t h i s type has been recognized only r e c e n t l y i n the b e l t . Two v a r i a n t s e x i s t .

The f i r s t i s gold-copper r i c h and i s a s s o c i a t e d w i t h mafic t o intermediate v o l c a n i c rocks of Upper T r i a s s i c age. This subtype i s ex e m p l i f i e d by the G u l l y Zone on Pass Lake's TREK property at Galore Creek. The G u l l y Zone was discovered i n the summer of 1988 and c a r r i e s 4-5% copper w i t h 0.2 ounces/ton gold over widths of 2 - 4 metres. I t s s t r i k e l e n g t h c o u l d reach 800 metres (2600 f t ) .

The second v a r i e t y i s represented by the Calpine g o l d - s i l v e r (lead-zinc) d i s c o v e r y at Eskay Creek announced i n November, 1988. D e t a i l s of t h i s f i n d are sketchy at t h i s stage but the dep o s i t i s s a i d to be a s s o c i a t e d w i t h f e l s i c v o l c a n i c s . A volcanogenic o r i g i n has been po s t u l a t e d by Calpine g e o l o g i s t s although the ore i s not thought to be massive i n nature. (3) Vein/Shear/Replacement

This c l a s s of de p o s i t has r e c e i v e d the most a t t e n t i o n i n recent years due t o the p o t e n t i a l f o r bonanza ore grades. T y p i c a l deposits are Snip (1.65 m i l l i o n tons of 0.65 ounces/ton Au) , Reg (1.0 m i l l i o n tons of 0.72 ounces/ton Au), Sulphurets (1.6 m i l l i o n tons of 0.34 ounces/ton Au and 22.9 ounces/ton Ag), S i l b a c k Premier (4.7 m i l l i o n tons of 0.39 ounces/ton Au and 8.8 ounces/ton Ag) and Doc (207,000 tons of 0.35 ounces/ton Au). Several of these ore bodies occur p e r i p h e r a l to porphyry gold-copper systems a s s o c i a t e d w i t h s y e n i t i c i n t r u s i v e bodies. (4) Skarns

This type i s a s s o c i a t e d w i t h the contact of i n t r u s i v e rocks and carbonate-bearing rocks. The carbonate hosts may l i e w i t h i n the Upper T r i a s s i c volcano-sedimentary assemblage or o l d e r P a l e o z o i c limestones which underly much of the v o l c a n i c b e l t . Examples i n c l u d e the Gulf I n t e r n a t i o n a l property i n the Iskut R i v e r d i s t r i c t and Pass Lake's TREK property. In the l a t t e r i n s t a n c e , l e a d , z i n c and s i l v e r (30% Pb-Zn, 49 ounces/ton Ag) have been found i n epidote-garnet-bearing skarn f l o a t .

Taken as a whole, the e n t i r e Upper T r i a s s i c package i n north western B r i t i s h Columbia appears t o have been remarkably productive f o r precious and base metals throughout the e v o l u t i o n of the b e l t from e a r l y volcanism and sedimentation (volcanogenic deposits) through l a t e - s t a g e plutonism (porphyry gold-copper, skarn g o l d , v e i n g o l d - s i l v e r ) . 3.0 GALORE CREEK CAMP 3.1 Overview

Wi t h i n the l a s t year, Galore Creek has been recognized as a n a t u r a l northward extension of the Stewart, Sulphurets and I s k u t gold camps t o the south. Major gold e x p l o r a t i o n p r o j e c t s c u r r e n t l y underway include C o n t i n e n t a l Gold's Trophy p r o j e c t and Pass Lake/Lorica's TREK j o i n t venture. A major s t a k i n g rush during 1988 i n v o l v i n g both major and j u n i o r companies promises t h a t the 1989 season w i l l witness a much higher l e v e l of a c t i v i t y ( F i g 3). Pass Lake's c l a i m holdings now comprise e i g h t w e l l - l o c a t e d blocks (406 u n i t s ) of which seven are a v a i l a b l e f o r j o i n t venture p a r t i c i p a t i o n i n four packages. 3.2 Geology and Ore Deposits

The Galore Creek camp i s u n d e r l a i n by Upper T r i a s s i c intermediate to mafic flows and b r e c c i a s and r e l a t e d sediments deposited on a basement of P a l e o z o i c carbonates and f i n e grained c l a s t i c rocks ( F i g 4 ). The Coast C r y s t a l l i n e Complex of mainly J u r a s s i c and younger g r a n i t o i d i n t r u s i o n s dominates the western margin of the map sheet. The l a r g e Galore Creek a l k a l i c complex forms the core of the camp. S t r u c t u r a l l y , the reg i o n i s very complex, being dominated by major steep-angle f a u l t s t r e n d i n g north west, north east and north. Thrust f a u l t s are b e l i e v e d t o be much more extensive than i n d i c a t e d on the map.

Several mineral occurrences are shown on the map d a t i n g from the e a r l y days of porphyry copper e x p l o r a t i o n i n the camp during the 1950's and 1960 * s. Foremost among them i s the Galore Creek porphyry gold-copper d e p o s i t (occurrence 2) as p r e v i o u s l y described.

Other s m a l l e r p o r p h y r y - s t y l e prospects i n c l u d e Copper Canyon (occurrence 12) h e l d by Canamax and Goat (occurrence 15) comprising a small c l a i m b l o c k h e l d by Consolidated S i l v e r Standard and completely encompassed by Pass Lake's TREK property.

The JW (occurrence 11) i s reported t o have returned g o l d assays up to 2 ounces/ton from a quartz v e i n sampled i n the e a r l y days of e x p l o r a t i o n i n the region. Recent r e p o r t s by the present property owners (Sarabat, B e l l e x ) confirm high-grade g o l d (4-6 ounces/ton) from quartz-sulphide v e i n s on the claims.

The P a y d i r t property (occurrence 13 - formerly Ann and Su) of Consolidated S i l v e r Standard/Longreach Resources has d r i l l - i n d i c a t e d reserves of 204,000 tons grading 0.12 ounces/ton gold i n s i l i c i f i e d and s e r i c i t i z e d v o l c a n i c rocks adjacent t o a s y e n i t e stock.

3.3 Current E x p l o r a t i o n A c t i v i t y

1988. Two major e x p l o r a t i o n p r o j e c t s were i n i t i a t e d i n the camp during

C o n t i n e n t a l Gold expended over $1,000,000 on i t s l a r g e Trophy property (184 sq. km/ 71 sq. m i l e s ) .

On Pass Lake's TREK claims (111 u n i t s / 28 sq. km) immediately to the south of the Trophy block, L o r i c a Resources spent $100,000 i n the f i r s t f u l l season of e x p l o r a t i o n on the property. The program y i e l d e d f i v e base/precious-metal t a r g e t s of s i g n i f i c a n c e . Of these, the G u l l y Zone i n i t i a l l y appears t o be the most i n t e r e s t i n g . I t i s a volcanogenic massive sulphide deposit w i t h a p o t e n t i a l s t r i k e length of 800 metres (2600 f t ) based on geophysics and geochemistry. Where exposed over a 60-metre length, two channel samples assayed as f o l l o w s :

APPENDIX "A" JD 1, 2 AND PL 1 GROUP

4.1 Geology and P r i o r Work The group comprises 60 u n i t s (15 sq.km) i n two separate blocks s t r a d d l i n g Scud R i v e r ( F i g 5). According t o the GSC, they are u n d e r l a i n by P a l e o z o i c c l a s t i c sediments/greenstones and carbonates ( u n i t s 2 and 3) 15 km north west of the Galore Creek porphyry gold copper d e p o s i t . On PI 1, the sedimentary rocks have been in t r u d e d on the west s i d e by a g r a n o d i o r i t e p l u t o n ( u n i t 17) of u n c e r t a i n age. I t i s t o be noted, however, t h a t there are known s e r i o u s i n a c c u r a c i e s i n the GSC mapping such t h a t the c l a i m geology must be considered t e n t a t i v e at the present time. D e t a i l e d mapping i s c l e a r l y r e q u i r e d . P o t e n t i a l t a r g e t s on these claims are volcanogenic massive sulphide, skarn and v e i n d e p o s i t s .

There i s no record of e a r l y work on the JD c l a i m s . During 1988, Pass Lake conducted p r e l i m i n a r y heavy-sediment, s o i l and rock sampling and p r o s p e c t i n g on p a r t s of the property. Three of four heavy-sediment samples c a r r i e d between 700 and 3720 ppb Au i n the main creek d r a i n i n g the n o r t h - c e n t r a l p a r t of the block. Of the 15 s o i l samples c o l l e c t e d , one returned 40 ppb Au i n the same area. Ten of 15 rock samples returned anomalous gold of 70 - 9620 ppb, s i l v e r of 3.6 + over 200 ppm and base metals, a l s o i n the n o r t h - c e n t r a l s e c t o r . Five of these exceeded 34 00 ppb Au. Selected rock geochemical anomalies were confirmed by four f i r e assays, which gave 0.102 - 0.270 ounces/ton Au and up t o 6.25 ounces/ton Ag.

No p r i o r work i s known to have been c a r r i e d out on the PL 1 c l a i m , which was staked by Pass Lake i n mid-October, 1988. However, the u n d e r l y i n g geology i s considered to be favourable and the ground l i e s only one k i l o m e t e r north west of a high-grade g o l d showing l o c a t e d on Jack Wilson Creek.

In c o n c l u s i o n , the JD 1, 2 and PL 1 claims o f f e r a unigue opportunity t o p a r t i c i p a t e i n a promising g o l d p r o j e c t i n an emerging gold camp. The presence of gold and s i l v e r i n rock has been demonstrated on the JD claims i n the course of a very p r e l i m i n a r y e x p l o r a t i o n campaign and the PL 1 c l a i m i s s i t u a t e d c l o s e t o a known high grade v e i n occurrence. A major e x p l o r a t i o n program i s needed to e s t a b l i s h the mine-making p o t e n t i a l of the p r o p e r t i e s .

APPENDIX "A" PL 2, 3 AND PL 4, 5, 6 GROUP

The group comprises two blocks t o t a l l i n g 75 u n i t s (19 sg. km) l y i n g t o the west of the Galore Creek porphyry gold-copper d e p o s i t ( F i g 5). The PL 2, 3 claims are shown as e n t i r e l y u n d e r l a i n by g r a n o d i o r i t e ( u n i t 17) of u n c e r t a i n age. However, i t i s known t h a t the contact between the p l u t o n and Upper T r i a s s i c v o l c a n i c rocks ( u n i t 9) t r a v e r s e s the eastern s i d e of the block. PL 4, 5 and 6 are u n d e r l a i n by Upper T r i a s s i c v o l c a n i c rocks on the margin of the Galore Creek a l k a l i c complex ( u n i t 12). P o t e n t i a l t a r g e t s on these claims are volcanogenic massive su l p h i d e s and v e i n d e p o s i t s .

No p r i o r work has been recorded on these c l a i m s , which were staked by Pass Lake i n mid-October, 1988. In 1964, Conwest h e l d a l a r g e c l a i m block t o the north but t h e i r work focused on the porphyry-copper p o t e n t i a l of the t e r r a i n west of the l a r g e Galore Creek gold-copper deposit. P r e l i m i n a r y prospecting i n 1988 on the Consolidated S i l v e r Standard claims immediately t o the west of the PL 4, 5, 6 block i s reported t o have encountered gold-bearing v e i n m a t e r i a l grading up to 1.5 ounces/ton.

In c o n c l u s i o n , the PL 2, 3 and P 4, 5 and 6 claims represent two p r i s t i n e p r o p e r t i e s w e l l l o c a t e d w i t h respect t o the Galore Creek gold-copper d e p o s i t and other gold-bearing p r o p e r t i e s i n the area.

APPENDIX "A" PL 7 - 11 GROUP

The l a r g e contiguous block of 100 u n i t s (25 sq. km) i s s i t u a t e d adjacent t o the P a y d i r t property of Consolidated S i l v e r Standard and Longreach Resources where d r i l l - i n d i c a t e d reserves of 204,000 tons of 0.12 ounces/ton g o l d have been announced ( F i g 5). Pass Lake's claims are shown as u n d e r l a i n e n t i r e l y by Upper T r i a s s i c v o l c a n i c rocks ( u n i t 9). A s m all g r a n o d i o r i t e stock ( u n i t 17) on the south-east edge of the c l a i m block i s s a i d to c a r r y some disseminated molybenite. On the P a y d i r t property, plugs of g r a n o d i o r i t e and a l s o s y e n i t e have been mapped, the l a t t e r l y i n g immediately north-east of the ore zone discovered on the property. S i m i l a r favourable i n t r u s s i v e rocks could e x i s t on the PL 7-11 c l a i m s , which have been p o o r l y mapped and explored.

L i t t l e p revious work has been done on the PL 7-11 c l a i m s , which were staked by Pass Lake i n the mid-October, 1988. In 1965, Bralorne-Pioneer Mines c a r r i e d out a program of g e o l o g i c a l mapping and s o i l geochemisty f o r copper on a small c l a i m block l y i n g west of S p l i t Creek near i t s confluence w i t h Porcupine R i v e r . R e s u l t s were i n c o n c l u s i v e .

In c o n c l u s i o n , the PL 7-11 claims represent a l a r g e p r i s t i n e property w e l l l o c a t e d i n the Galore Creek camp. S i g n i f i c a n t g o l d has been found on adjacent ground and the l a r g e Galore Creek porphyry gold-copper d e p o s i t l i e s only e i g h t k i l o m e t e r s t o the north east.

APPENDIX "A" WISER 1, 2 AND CUTTY

These two c l a i m blocks c o n s t i t u t e 60 u n i t s (15 sq. km) lo c a t e d a short d i s t a n c e west and north of Pass Lake/Lorica's impressive TREK property and w i t h i n a rad i u s of 10 kil o m e t e r s from the Galore Creek porphyry gold-copper deposit ( F i g 5). The Wiser claims are u n d e r l a i n by Upper T r i a s s i c v o l c a n i c rocks ( u n i t 9) intruded by a g r a n o d i o r i t e stock ( u n i t 17) near the western boundary. The Cutty c l a i m i s un d e r l a i n by Upper T r i a s s i c v o l c a n i c s ( u n i t 8) and Permian limestones (un i t 4) i n f a u l t contact along a major north-south s t r u c t u r e . No previous work i s recorded f o r the two c l a i m b l o c k s . During 1988, Pass Lake conducted p r e l i m i n a r y heavy sediment (3 samples), s o i l (26 samples) and rock (13 samples) sampling and prospecting on the eastern part of the Wiser c l a i m s . One heavy sediment sample returned 53 0 ppb Au and one s o i l sample 370 ppb Au. F i v e rock samples c a r r i e d 35 -75 ppb Au w i t h one sample r e p o r t i n g 4.0 ppm Ag.
