Property No. 2

Shades of Green - Tenure #1024589
4 cell units - 80.66 hectares

Latitude                51º 23' 59.7" N
Longitude            119º 24' 04.3" W

This tenure does not have a MINFILE reference.

Centered on coordinate 51º 23' 59" N, 119º 24' 04" W, the Shades of Green mineral tenure is located on the east side of Adams Lake, 36 kilometres northwest of Seymour Arm.  Access is by way of Forest Service Roads, which meanders and services most areas of the claim.  The prior tenure holder indentified the presence of 'green crystals' but no other information had been made available.  The general location is consistent with other reports of iolite and varied semi-precious stones.

Bedrock over the claim area is divided along a contact zone, with metamorphic rock types intruded by quartz monzonitic intrusive.  Tsikwustum Creek drains south-westward along the southern sector of the claim area, with Michael Creek draining south-westerly along the northern side of the tenure.  A regular fault cuts through the entire length of Adams Lake. 

This property is ideal for further exploration.

Cream Minerals Ltd

Results from the exploration program on the Kootenay Gemstone Property (Beryl Three) has defined several beryl occurrences and has led to the definition of areas with potential for additional occurrences. Several brilliant blue gem quality beryl (aquamarine) crystals have been found. The majority of the beryl crystals located by prospecting are pale to medium blue in colour and often opaque with occasional clear (gemmy) crystals or clear patches within the crystals. Many pale olive-green or blue-green beryl (emeraldlaquamarine) crystals have also been found, as have minor clear, white and yellow (heliodor) coloured beryls. Soil and rock sample results have shown areas of elevated beryllium consistent with the occurrence of beryl-bearing pegmatite dykes. Also of importance, soil and rock amples with high chromium values have been obtained, indicating areas with higher potential for green emerald crystals.

The main showing contains bluish-green beryls (aquamarine), some with significant gemmy sections. Of particular interest to emerald exploration at this location is the presence of Cr-rich gabbroic host rocks that contain up to 364 ppm Cr. This value falls well within average Cr values of mafic host rocks proximal to emerald mineralization at Regal Ridge in the Finlayson District of southeast Yukon (Groat et al., 2002).

In the southern claim units (Topaz, Columbian), 1 to 1.5 metre wide pegmatite sills are most common, hosted in biotite-muscovite schists of the Middle Aldridge Formation. Light bluish-white and yellowish white, opaque beryls are the most common, while translucent beryl crystals up to 5 centimetres long have been noted

Commodities             Beryl    Deposit Types    O01 : Rare element pegmatite - LCT family

Capsule Geology    The Humm and Toby claims are located on southern ridge of Hulme Peak, between Toby and Topaz Creeks. From 2003 to 2005, the claims were explored as a part of the Kootenay Gemstone property of Cream Minerals Ltd., including the Laib Creek, Rusty and Cultus showings to the north.

The area is underlain by granites and granodiorites of the middle Cretaceous Bayonne Batholith (Shaw Creek stock) and sediments of the La France Group and Middle Aldridge Formation. Pegmatites cut all rock types and host beryl crystals.

Locally, the area straddles the contact between the Shaw Creek stock and the Mount Nelson Formation and pegmatite dikes are hosted predominantly within metamorphosed sediments of the Middle Aldridge Formation. Medium grey quartz feldspathic biotite-muscovite schists with rare kyanite are most common. Lesser volumes of dark grey biotite-amphibole± garnet schists may be interlayered with the above.

The main showing contains bluish-green beryls, some with significant gemmy sections. The largest beryl collected to date is a euhedral, hexagonal, translucent crystal with dimensions of 4.0 by 0.8 centimetres (Assessment Report 27850).

SUMMARY

Beryl        Deposit Types    O01 : Rare element pegmatite - LCT family

 

Capsule Geology  The Rusty claims are located on the western flank of Mount Burnett Mountain, approximately 1.5 kilometres south of Cultus Creek. From 2003 to 2005, the claims were explored as a part of the Kootenay Gemstone property of Cream Minerals Ltd., including the Laib Creek and Cultus showings to the north.

The area is underlain by granites and granodiorites of the middle Cretaceous Bayonne Batholith (Shaw Creek stock) and sediments of the La France Group. Pegmatites cut all rock types and host beryl crystals.

Locally, two significant beryl showings have been located within the Rusty claims (Assessment Report 27850).

The original showing, known as the Rusty showing, is located approximately 3 kilometres south of the Cultus showings. It is characterized by trace amounts of blue, opaque, subhedral beryl and trace pyrite in simple, narrow quartz-feldspar pegmatite veins oriented 048/44SE.

The second showing, also known as the Jarrod’s showing, is located approximately 2 kilometres south of the Cultus showings. It is characterized by a sparse swarm of fine- grained pegmatite veins and narrow dikes, containing 90 per cent feldspar, 8 per cent grey quartz, and minor muscovite, hosted in a K-feldspar–phyric quartz monzonite. Rare to occasional beryls occur as white to blue, opaque to translucent, euhedral crystals up to 1.5 centimetres in diameter.

Rusty Claims
Two significant beryl showings have been located within the Rusty claims. The original
showing, located approximately 3 kilometres south of the Cultas showings, is
characterized by trace amounts of blue, opaque, subhedral beryl and trace pyrite in
simple, narrow quartz-feldspar pegmatite veins oriented 048144SE. Along the ridgeline,
approximately 200 metres east of this showing is a rusty clearing, from which the claim
group gets its name. The rusty zone is underlain by a gossanous actinolite bearing skarn,
and minor pyroxenite float. Limited prospecting in the area has revealed only poor
quality beryl specimens. However, the showing is unique and of interest from a
mineralogical point of view, as it is hosted in dolomitic limestone. The presence of
pyroxenite is also of interest as a potential chromium source.

The second showing within the Rusty claim group is located approximately 2 kilometres
south of the Cultas showings, on and just west of the ridge, 1 kilometre west of Mount
Burnett. This showing is casually being called "Jarrod's showing", by field personnel. It
is characterized by a sparse swarm of fine grained pegmatite veins and narrow dykes,
containing 90% feldspar, 8% grey quartz, and minor muscovite. Rare to occasional
beryls occur as white to blue, opaque to transleucent, euhedral crystals up to 1.5
centimetres in diameter. Two or three specimens were collected from this locale. The
host is entirely K-feldspar phyric quartz monzonite. It appears that the showing is located
a significant but unknown distance from the country rock contact. Quality of the beryls
(aquamarines) in this area is encouraging. More work should be done to determine the
extent of the beryl mineralization and to locate the contact in this area along strike of the
known beryl occurrences.

Significance of Host Rock and Pegmatite Character in the Northern Claim Areas
Pegmatite veins and dykes at the OMG claims are predominantly hosted within the fineto
medium-grained, equigranular, leuco-quartz-monzonite (unit G). To date, this phase of
the Shaw Creek Stock, has only been observed in the OMG claim area. This phase
appears to comprise the northwestern limit of the Shaw Creek Stock, with approximate
maximum dimensions of 300 x 300 metres. Its southeastern limit, close to the Linda
Showing at approximate grid coordinate O+OON 6+00E, trends approximately 060'. Here
it is in contact with the preeminent and extensive K-feldspar megacrystic biotite
monzonite (unit Gk).

In the OMG grid area, pegmatites occur in both phases of the Stock (G and Gk). There
are however some distinct differences, in terms of pegmatite texture and beryl
mineralogy, between pegmatites found in the G-phase as opposed to the Gk-phase.

Pegmatites mapped within the OMG grid, are all hosted in the G-phase (with exception to
the Linda vein). The coarsest and most chemically fractionated pegmatites found on the
entire property are located within this area. Beryl crystals, where present, can attain
diameters in excess of 20 centimetres. Crystals this large are extremely rare elsewhere.
On the downside however, blue colouration of aquamarines within the OMG grid area,
are on average, less intense than aquamarine crystals in pegmatites hosted in the Gkphase.
The best colour blue crystals, found to date, are found at the Linda Vein and at the
Cultas claims, both of which are hosted in the Gk phase.

Pegmatites of the northern claim units normally occur in swarms. At the OMG grid, the
percentage of P and PG within unit G is relatively high, perhaps as much as 10% by
volume of the total volume of intrusive. This is in contrast to a significantly lower
density of pegmatites everywhere else in the northern claim areas. Pegmatites at the
Cultas and Rusty claims generally occur within distinct structural corridors, perhaps
limited to 50 to 100 metres wide. What controls the distribution of these pegmatite-rich
corridors in the area is still not understood. More detailed prospecting and mapping of
the contact in this area would begin to address this question.

Capsule Geology    The Lloyds Mine beryl occurrence is located on a north east ridge of Mount McGregor, approximately 2 kilometres west of Kootenay Lake. In 2001, the area was prospected by L. Addie.

Regionally, the area is underlain by granite and granodiorite of the middle Cretaceous Bayonne batholith and interbedded grey siltite and black argillite of the La France Group.

Locally, pegmatite dikes host beryl in the Bayonne biotite granite and at the contact of the La France sediments. The dikes trend north east and dip south east. Eocene syenite is noted cutting off beryl- bearing pegmatites. The majority of beryl occurs as blue-green and opaque crystals ranging in size from a few millimetres to one centimetre wide and three centimetres long.

In 2001, sampling returned up to 400 parts per million beryllium and one “tiny” clear blue aquamarine beryl (Assessment Report 26955).
