Hi 1King,

I'll try and dig up that information for you.

As far as the lawsuit, these things tend to drag on and on. Our lawyers are dealing with it. (Two of our board members and lawyers).

Cheers,

Kent

Hi 1King,

Here is what I found on the petrographic examination of the core from Okak Bay:

Preliminary Report on the Petrographic Examination of Polished Thin Sections from the Gallery Resources Limited Okak Property

1998.01.25

Introduction
On 1998.01.23, Mr. Victor French, representing Gallery Resources Ltd., requested that Dr. Derek Wilton, P.Geo., provide a written report on the preliminary petrographic examination of 17 polished thin sections. These sections had presumably been prepared from drill core samples collected from the Gallery Resources Ltd. drilling program at their Okak Property. I have not visited the property, nor collected the samples. It must also be noted that this is a preliminary report and as such may be subject to revision upon more complete examination of the sections; it should not be construed as the final word on the petrography of these samples.

Sample 1-5 494.0 - 494.25
This samples contains ~40% sulphides, of which >90% is pyrrhotite. Pentlandite is present as flames and lamallae within the pyrrhotite, and also as larger masses, up to 0.15 mm across. Minor chalcopyrite and rare pyrite are also intergrown with the pyrrhotite.
The host rock is best described as a pyroxene gabbro with an overall cumulus texture of 45% plagioclase, 40% pyroxene and 15% biotite. The largest biotite grains are up to 8 mm long and are associated with sulphide typically as rims between the sulphide and host rock. This obviously formed from a volatile-rich magma and this particular sample contains the most biotite seen in any of the sections examined. The host troctolite at Voisey's Bay contains abundant biotite.

Sample M155 549.6 - 549.8
This rock is a gabbroic anorthosite with up to 25% intergranular subhedral pyroxene crystals in the plagioclase crystals. There is up to 3% biotite. The rock also contains up to 10% sulphide which is dominantly pyrrhottie with 20% chalcopyrite. Pentlandite flames and lamellae are intergrown with pyrrhotite. There is a further 5% magnetite intergrown with the sulphide.

Sample 588.60
This is an anorthosite containing large anorthite crystals up to >8 mm long. The sample also contains 10% magnetite and 1-2% pyrite. Pyroxene and biotite are intergranular. There is strong carbonate and sericite alteration in places; there is one large carbonate patch up to 4 mm across.

Sample 656.44
This is a graphic granite with coarse intergrowth textures of quartz and microline; the quartz lamellae are up to 0.4 mm wide. Biotite is present as elongate flakes and large masses up to 4 mm across. Muscovite is also present and there is a slight chloritization of the biotite. There are no opaques.

Sample 659.14
This is a pyroxene gabbro with 50% plagioclase, 40% pyroxene, 3% biotite, and 7% magnetite (av. 0.4 mm in dia.) and rare pyrite grains. Plagioclase is mainly anhedral but also slightly subhedral; pyroxene is anhedral. Typical gabbroic texture with no preferred orientation of felted textures within plagioclase.

Sample 714.8
This is an anorthosite with up to 20% pyroxene patches. Some of the pyroxene consists of augite lamellae in hypersthene. There is strong carbonate alteration in places. Pyroxene is locally heavily altered and/or intergrown with biotite. Magnetite is intergranular and contains minor pyrrhotite and pyrite.

Sample 883.0
This is a two-pyroxene gabbro consisting of 30% pyroxene intergrown with subhedral to anhedral plagioclase crystals. Hypersthene contains augite lamellae. 10% of the rock is comprised of intergranular magnetite with 5% pyrite and minute chalcopyrite.

Sample 903.8
This is a granite with carbonate alteration and fracture-fillings, sericite occurs with the carbonate. Relict biotites(?) are pseudomporphed by chlorite. There is an overall reddish tint to the rock indicative of oxidation. The rock is highly fractured in part, and some fractures are actually cataclastic breccia zones up to 1 mm wide.

Sample 1053.1
This is an anorthosite with 92% plagioclase overgrown by sericite and muscovite. There are 3%, small (=/<0.4mm), intergranular, totally pseudomorphed, pyroxene grains and minor biotite. There are 3% magnetite grains, up to 2 mm in dia., with rare intergrowths of pyrite and even rarer, minute, chalcopyrite.

Sample 1077.7
This is an anorthosite with =/< pyrrhotite (and pyrite) and =/< 1% magnetite. There is one very large plagioclase crystal present which is up to 32 x 50 mm. Pyroxene is present as small "droplets" within the large plagioclase. There is slight sericitic dusting of the plagioclase and some fracturing.

Sample 1197.8
This is an anorthosite with subhedral plagioclase laths up to 5 mm long. The rock is broken in places with strong chlorite replacement between plagioclase crystals. The rock is cut by sericite-carbonate-filled fractures. The only opaque is splotchily hematized magnetite crystals and rare pyrite.

Sample 1257.3
This is an anorthosite with cumulus type anhedral plagioclase and round pyroxenes as inclusions within plagioclase; av. dia of pyroxene is 0.8 mm, plagioclase is up to 2 mm diameter. There is abundant fracturing in plagioclase and pyroxene, but no strong alteration. The only opaques are small magnetite grains.

Sample 1321.2
This is an anorthosite with strong carbonate alteration, abundant sericite and strong saussiterization of plagioclase. Pyroxene is highly altered. There is some magnetite present.

Sample 1338.2
This section is basically of one large single plagioclase crystal with a 4 mm wide quartz vein cutting through. The quartz is mylonitied and subgrained. There is strong secondary muscovite developed in the vein with intergrown minute magnetite crystals. Rare pyrite and even rarer chalcopyrite are intergrown with larger magnetite crystals.

Sample 1361.0
This is a granite with quartz, mircoline, albitic plagioclase and biotite; the latter of which is slightly to highly chloritized. The opaques are =/< 5% magnetite which is slightly skeletal in places. Plagioclase is slightly saussiterized.

Sample 1361.9
This is a granite with micrographic to myrmekitic intergrowths of quartz and feldspar. Magnetite accounts for 3-5% of the rock. Biotite, where present, is typically chloritized.

Sample 1378.2
This is an anorthosite with coarse grained lath-like, subhedral, feldspar crystals up to 4 x 10 mm. There is minor muscovite-sericite-chlorite alteration, locally with epidote needles. Opaques are =/< 10% magnetite, which is slightly corroded, are rare pyrite.
