1.0 INTRODUCTION

This is a short report on the Black Bay Opal Property located near Monte Creek in the Kamloops Mining Division of British Columbia and was requested by the owner. There have been several recent discoveries ofcommon and precious opal in the ridge area on the Black Bay mineral claim in the northern pari of the property. This report is based on a two day field examination of the opal occurrences and surrounding area in the company of the owner Mike Bobyk. The fieldwork was followed by research, opal sample examination and preparation of this report.

This report has a dual purpose and is being used for both assessment work credit and property promotion-reference. The author is an independent consulting geologist based in Kamloops, BC. He is not and accredited gemologist but does have an extensive background in mineralogy, petrology and mineral exploration including epithermal (lower temperature) gold deposits.

1.1 LOCATION AND ACCESS

The Black Bay Property (the property) is located in south-central British Columbia, 25 kilometres cast of Kamloops (Figure 1 ) and approximately 6 kilometres southeast of the settlement of Monte Creek. Map coverage is by NTS sheet 82L112 (west half) with the centre of the claim group having approximate UTM coordinates of 0294540E and 5608700N.

The Kamloops-Vernon Highway 97 and CN rail line follow the Monte Creek valley proximal to the eastern property boundary. Access to the property from Highway 97 is via the Barnhartvale road from the Ducks Meadow railway crossing west for 2.5 kilometres. From this point access is through a locked gate (north side) opposite the Flatt ranch then north and cast via a series of ranch trails with sever.31 gates. These yield excellent access to most parts

I Figure 1: PROPERTY LOCATION MAP 3 of the property. The area covered by the mineral claims is on private ranchland, permission is required for access to the property from the gate on the Barnhartvale road.

1.2 PHYSIOGRAPHY

The property lies in an upland area of gentle rolling hills and northwest trending ridges with the South valley to the north and Monte Creek valley to the east. Elevations on the property are in the 640 to 5'20 metre range. Local outcrops of bedrock occur along ridge tops and low cliffs (up to 20 metres high) mainly in the northern area. Much of the property area is cleared ranchland with local stands of mature pine on the higher ground. There is little surface drainage which is largely restricted to a few small swamps and intermittent drainages.

1.3 PROPERTY

The Black Bay Property consists of 5 continguous mineral claims in the Kamloops Mining Division of British Columbia and are 100% owned by Mike Bobyk of Falkland BC (owner number 143560). There are in total 5 two-post (single unit) claims covering approximately 125 hectares with locations shown on Figure 2 and tenure data in Table 1.

c, As mentioned earlier the mineral claims are on private land. In 2002 M. Bobyk made agreements with both R. Nichol and H. Flatt (ranchers) for access and surface work.

1.4 EXPLORATION HISTORY

There are no records of any previous exploration for semi-precious or precious stones in the claim area. The Tertiary age volcanic rocks between Vernon and Kamloops have been explored by rockhounds for semi-precious and decorative stones such as agate, chalcedony, amethyst and common opal throughout the last century. Significant interest was generated by the discovery of precious opal near MiGregor Creek in 1991 followed by the development of the Klinker Opal Deposit by Okanagan Opal Inc. (23 kilometres WNW of Vernon). Adequate reserves have been identified for a small scale mining operation, commercial production is however dependent on developing a market for Klinker precious opal (R. Yorke-Hardy, 1999).

c) Preliminary exploration for agate in 2001 resulted in the discovery of common and precious opal (and agate) in float ;and bedrock basalt by the owner. This was followed by the staking of the Black Bay mineral claim. Further opal discoveries along the cliff by the owner and friends in 2002 resulted in the resi:aking of the Black Bay and addition of Black Bay 1,2,3and 4 two-post claims between July and October 2002. Further prospecting and limited stripping of bedrock in 2003 has revealed common opal and local patches of precious opal in several areas proximal to the original discoveq. These are spaced over a 150 metre length along the cliff.

1.5 REGIONAL AND LOCAL GEOLOGY

The Monte Creek area is located in the Intermontane Belt of the Canadian Cordillera in the southern part of the Quesnellia Tenane. Within this section of Quesnellia the Upper Triassic to Lower Jurassic age Nicola Group features basic metavolcanic rocks with local metasediments (siltstones and phyllite). These unconformably overlie metasedimentary and metavolcanic rocks 10 R. C. Wells, P.Geo., FGAC. Kamloops Geological Services Ltd. 6 L, of the Harper Ranch Group (Devonian to Triassic). Both these formations are intruded by Middle Jurassic age granitic rocks. An extensive cover of volcanic (dominated) rocks of the Kamloops and Penticton Groups (Eocene age) stretches from Kamloops Lake to Okanagan Lake and forms much of the higher ground.

The extent of the Kamloops Group volcanic cover is clearly apparent in Figure 3 taken from the geological map by A.G. Jones in GSC Memoir 296 for the Vernon map area (1959). More detailed mapping of the Kamloops Group in the area is available from Peter Read’s work in 1996 (Explore BC.). This mapping covers Robbins Range and Ducks Meadow west and south of the property. The most widespread unit consists of grey aphanitic to weak porphyritic (augite i olivine) basalt, andesite and lesser dacite volcanic flows (EDva) with some interflow breccia. A large component of volcanic breccia (Edvax) is indicated in the Robbins Range area.

The same report by Read i(1996) also addresses the industrial mineral and precious metal potentials. Read draws attention to the widespread occurrence of agate in lavas, scattered common opal and rare precious opal. The discovery of precious opal on the Klinker claim in 1991 and Ewer in 1992 (Figure 3)were the first recorded in British Columbia and Canada. Read identified 2 precious opal occurrences all on NTS sheet 82L/5E. These are shown on Figure 3 and outlined in the Table below.

(See Figure 3)

The Klinker property of Okanagan Opal Inc. features several concentrations of precious opal hosted by Kamloops Group volcanic breccias and lahar with thin andesite or basalt flows and intrusions. These lie within 100 rnetres of the basal unconformity with underlying Paleozoic age rocks. Precious opal, agate and common opal fill fractures and cavities in the volcanics. The opal exhibits variable base colours ranging from transparent, water clear to clear amber to translucent opaque white to dark brown and exhibits a variable intensity ‘play of colour’ in a flash pattern. The following was taken from an article by R. Yorke-Hardy (Canadian Rockhound 1999, Vol. 3. No. 1) and covers the base coloW:j of opal at Klinker.

0 Transparent to opaque common and precious opal in a broad range of base colours is found on the property.

0 The transparent precious opal and non-precious opal ranges from water clear to light to yellow to amber to orange similar to Mexican ‘fire opal’.

0 In 1997 the first “Eloulder Black” and “Boulder Brown” opal was produced from the Klinker Property. To date precious opal (opal with a play of colour) has been found in all of the various base colours except the grey-black types. To date no “precious black opal” has been found on the Klinker Property.

2.1 INTRODUCTION

The property features several closely spaced common and precious opal occurrences on the Black Bay mineral claim number 394767 (Figure 2). All of these are prospecting discoveries by the property owner and friends over the last two years and lie within the northwest quarter of this claim. There are no records of opal occurring within the claim area. Some references have been made by local rockhounds to common opal in the Robbins Range area several kilometres to the west.

~ I This section documents a two day property examination by the author on April gthand 30'h I I j at the request of the owner. A significant amount of time was also spent examining opal and agate specimens taken earlier by the owner from the showing area. Photographs taken by the author of selected specimens and the discovery showing (Plates 1 to 7) are located in Appendix A for reference.

2.2 APRIL FIELD EXAMINATION

This examination was mainly of the known opal occurrences and surrounding area along the main ridge and cliff on the Blxk Bay claim. A visit to the initial post and claim line indicated that they were correctly located (hy GPS) with coordinates 0295042E and 5608792N.

There is excellent truck access to the property and showing area by ranch trails. One trail follows the valley along the west side of the ridge and cliff within less than a hundred metres of some of the opal occurrences. The cliffs forming the Southwestern side of the ridge are subvertical up to 20 metres high with steep talus slopes below. Patchy outcrop occurs along the

R. C. We&, P. G,?o.,FGAC. Kamloops GeoIogicaI Services Ltd. 10 ridge crest above and the southea:sternslopes. This area on the claim features patchy tree coverage, care has to be taken on the steep cliffs and unstable talus slopes.

The ridge features a sequence of massive to columnar jointed basalt to andesite-basalt flows. These are medium to dark greys to green greys, fine grained to aphanitic and probably belong to unit Edva (Read, 1996). Columnar joints plunge NNE at 40' to 50' suggesting that flow units strike NW. with SW. clips. This is supported by the attitudes of high vesicular to amygdaloidal units (flow tops-bottoms?) in the showing area at the cliff top.

The Main Opal Occurrence is illustrated in Plate 1 and features a stripped area of about 50 square metres at the cliff top with patchy outcrops above. A narrow vertical slot in bedrock lies just to the south and follows ,3 steep westerly trending fracture set. Since discovery in 2001 a significant number of common and precious opals have been extracted from this area ( some shown in Plates 1 to 7). The hosl basalts are full of elongate commonly aligned vesicles and amygdales up to several centimetres in length, some larger cavities are up to 20cm long. Precious-common opal, agate-chalcedony and a variety of other white to greenish coloured minerals including clays and probable zeolites form space and fracturing fillings. The opal and agate often occur together, both fill primary cavites such as vesicles as well as fine fractures (often interconnecting) as illustrated in Plate 3. Opal filled fractures based on this preliminary examination appear to have three preferred orientations, striking 050 (N. dip), 290 (S. Dip) and 325 (NE dip) with widths locally exceeding 1 metre. Variably banded agates up to lOcm in diameter have grey, white and clear bands with local semi transparent colourless and white opal bands and laminae (Plates 4 and 5). Transparent to opaque opals are common and precious opal occurs in a broad range of base colours including transparent, white, green, orange and browns. Precious opals display pinfire, mosaic (harlequin) and flash play-of-colour with variable brightness. Colours often include red, green and some blue, local violet. Opal characteristics are discussed further in Section 2.3.

R. C. Wells, P. Geo., FGAC. Kamloops Geological Services Ltd. 11

The Cliff area below the main showing features more massive basalt with local fracture controlled, lensy veinlets of white to dark coloured common opal up to 4mm wide. Many of these have NNE strike with vertical to steep east dips. No precious opal was observed during a relatively short examination. The talus at the base of the cliff contains surprisingly little opal on initial inspection considering the fairly abundant material at the cliff top. Closer examination however reveals local numerous small white opals and local veinlets.

The cliff top area 15 to 30 metres NW. of the main showing features a prominent joint- fracture set striking 340' with intermediate to steep west dips. A traverse down this feature on the upper cliff face revealed fairly abundant centimetre scale, light coloured agates. There are also local concentrations of small (

0 A fourth area of opal occurs 100 metres east of the main showing along some low cliffs of amygdaloidal basalt. This area has fairly abundant dark coloured agate with black (flint like) and banded browns as well as the more common light colours-grays and whites. Some dark coloured opal may also be present as local weak red flashes were observed (in fractured material!). Some small white opals were observed but are common, rarely precious with low brightness pinfire.

A very limited amount of time was spent examining outcrops along the ridge top and cliffs to the northwest of the showings. Local agate and sparse small white opals? were observed in the lower cliff and talus. A significant amount of more detailed prospecting is required especially along the poorly exposed ridge top. Patchy lichen growth on outcrop often make prospecting for opals, especially when small difficult.

0 2.3 PRELIMINARY COMMENTS ON BLACK BAY OPALS

During and after the field examination the author examined well in excess of fifty opal samples mainly from the main showing area. Precious opal samples previously collected from this area by the owner have similar characteristics, size and host rock to those observed at the showings. The author has no reason to believe that they were taken from elsewhere. A few preliminary comments follow on Black Bay opal characteristics. Reference should be made to Plates 1 to 7 in Appendix A.

The first important observation is that virtually all the opal and opal-agate samples displayed cracks. The density of cracks was highly variable depending on the sample. Almost all of the opal material was taken frc’m surface (or very close) and extracted using hammer, chisel and pry-bar. Dehydration cracking appears to be a problem with some (but not all) of the older samples held by the owner, lacquer coated samples appear to have faired better. 0 As mentioned earlier the opal at Black Bay displays a variety of base colours including colourless, white, grey, green, pink, orange, brown and possibly black? These can be transparent, translucent to opaque. The precious opals display variable, locally brilliant ‘plays of colour’ with common reds, greens, blue-violels as shown in Plate 4 to 7. Pinfire, mosaic (harlequin), flame and flash were all observed in the sample suite. Some crystal opal exhibits red flash with strong directionality (Plate 1).

The size and shape of opds are highly variable in both bedrock and float. Some centimetre scale common and precious opals exhibit good oval shapes (vesicle fillings) as shown in Plates 2,6 and 7. Others can be highly irregular and vein like (Plate 3) or interbanded- laminated with agate (Plates 4 and 5). The latter exhibit impressive often brilliant plays in colour (reds and greens) and were some of the larger precious opal samples. Opal size ranges from

0 R. C. Wells, P.Geo., FGAC. Kamloops Geological Services Ltd. 1

millimetre to several centimetres. One of the larger was an irregular shaped, space filling crystal opal ( fragments illustrated in P1ai:e 1) that featured local flashes of red.

Some of the precious opal examined with darker green and brown body colour and two or more flash and millimeter patch colours probably qualifies as 'black opal'. Black opal has not been recorded from the known precious opal occurrences nearer to Vernon including the Klinker. Deposit.

'ci R. C. Wells, P.Geo., FGAC. Kamloops Geological Services Ltd. 14

3. CONCLUSIONS

The Black Bay mineral claim hosts a very significant common and precious opal occurrence in massive to columnar jointed Kamloops Group (Tertiary) mafic volcanic flows.

This is the first documentation of precious opals in the Monte Creek area. Three separate occurrences do occur on adjacent map sheet 082L/05 closer to Vernon including the Klinker deposit of Okanagan Opal Inc. (only known deposit in Canada). Black Bay may also represent one of the first occurrences of ‘bl.ack precious opal’ in British Columbia.

I The author was impressed by the density and variety of opals in the discovery area with a I range in base colours and plays in colour often including red. All of the opals observed in bedrock were primary or secondary space fillings and there appeared to be a fairly strong I fiacture/joint control on distribution. The main occurrences at the cliff top occur within a 0 vesicular to amygdaloidal unit.

The potential for further precious opal discoveries and enlarging the known showing area are considered excellent. It is too early to comment on the economic potential of this occurrence without expert opinion and some test finishing of opal gemstones.

4.0 RECOMMENDATIONS

The author is non an accredited gemologist but does have a background in mineralogy, petrology and mineral exploration. Based on personal examination the potential for gemstone opal on this property appears excellent.

Further prospecting for opals on the property is strongly encouraged as ‘nests’ of betteI grade opal are probable especially in areas with the correct fracture age.

Several opinions on the qoality and potential of Black Bay precious opals (by accredited gemologists) are required at this lime. This would be of great help in guidance for future exploration and development.

It would be very useful to compare opal characteristics following different extraction techniques in particular rock-chisel compared to rock saw. It would also be useful to compare if possible opals from different lev& relative to surface. The longer term stability of opal from Black Bay is an unknown. At the Klinker deposit surface opal is hydrophane but becomes more solid with depth (Minfile capsule geology).

All opal samples extracted from the property should be kept in a safe place and numbered by locality with date for future reference and control. Access to the opal showings should be restricted to visits with the owner.
