1. INTRODUCTION
Goldbrook Ventures Inc. (GBK) conducted prospecting, geological mapping and sampling work on its Belanger and Bravo properties, in Nunavik Québec, from July to September in 2007. The two properties are part of six claim blocks owned 100% by GBK, namely Wakeham, Ungava, Masuparia, Nuvilik , Bravo and Belanger. The purpose of the summer 2007 prospecting and geological mapping program was to continue to explore for magmatic nickel sulfide deposits, in conjunction with airborne geophysical surveys, ground geophysical surveys, and diamond drilling that were also conducted in the summer of 2007.
Prospecting and mapping was conducted in 13 areas on the GBK property, including Bravo West, Bravo East, Delta South, Delta East, Echo, Hellcat, Kozmo, Pillow Lake, East Pillow, PAD, R2, SuperFortress and Timtu. The following compilation report is a summary of the geology encountered in these areas together with assay results for select samples. At the end of the 2007 exploration season, 361 geological stations had been made and 93 grab samples had been collected for assay analysis. Appendix 2 and 3 contain all the raw geological and geochemical data, respectively. All grab samples were sent to ACCURASSAY Laboratories in Thunder Bay, Ontario and the samples were analysed for base and precious metals. Assay certificates have been included in Appendix 4 of this report.
Several areas showed favourable geology and encouraging assay results, and maps with the best nickel, copper and PGE+Au grades have been included in this report. Several geologists were responsible for mapping and prospecting in the summer of 2007, and Appendix 1 is a stand alone report compiled by M. Liard, one of the six geologists. The property geology section in this report is a compilation and summary of the notes made by the above mentioned geologists. Recommendations and suggestions for further exploration in 2008 are primarily based on their comments.

The Wakeham, Ungava, Masuparia, Nuvilik, Belanger and Bravo properties are located within National Topographic System (NTS) sheets 25E/05, 35F/01, 35F/02, 35F/08, 35G/04, 35G/05, 35G/06, 35G/07, 35G/09, 35G/10, 35G/11, 35H/12, 35H/05, 35H/09, 35H/11, 35H/02, 35H/06, 35H/07, 35H/08, 35H/10, and 35H/11 (Fig. 1) in northern Quebec (Nunavik). The centre of the project area is located approximately 10 km south of Xstrata's (Katinniq) mine. From the centre, the project area extends 70 km to the east and 100 km to the west and southwest (Fig. 2).
The hamlet of Salluit located on the arctic coast approximately 93 km north of the properties, serves as the primary access point to the project area, with daily scheduled commercial flights (First Air, Air Inuit) from Montreal, Ottawa and Igaluit. Heavy equipment, fuel and freight can be shipped to Kangiqsujuaq by ocean barge, with arrivals in July, August and September, and transported to the field area by ski-equipped aircraft before the spring ice-breakup or by large helicopter (e.g., B214ST or Sikorsky S61).
The base of field operations for the Goldbrook Raglan Project was the Guindeau camp, located on the south shore of Lac Guindeau (572282 mE, 6828269 mN; NAD 83 Zone 18). During the summer, the properties are best accessed by helicopter. Float planes can land at the Esker Lake airstrip and supplies transported by helicopter 30 km east to Guindeau camp. There are at least three other airstrips in the region: Katinniq (Raglan mine), Purtuniq (Asbestos Hill), and Deception Bay. The Katinniq airstrip is a private airfield controlled by Xstrata Nickel (formerly Falconbridge Ltd). The remaining airstrips are listed in the 1995 VFR Aeronautic Navigational Map as abandoned and in uncertain condition.

The project area is located north of the tree line. Topography ranges from rolling hills at -300 metres above sea level on the Belanger property in the west to >600 metres above sea level on the Wakeham property in the east. Outcrop exposure ranges from very poor to excellent. In some areas, exposed rock has been affected by frost action, reducing many outcrops to heaved rubble and angular blocks. Lowland areas are typically covered by till and boggy tundra to swamps, with scattered boulder fields of frost-heaved blocks and cobbles. The entire region is subject to permafrost to depths of up to 540 metres. Vegetation consists mostly of grass and moss.
Typical fauna in the region include caribou, wolf, fox, hare, snowy owl, Peregrine Falcon, Canada geese, and rodents. There are no black bears this far north, but Polar Bears have been sighted sporadically on the properties since 2004. Local rivers and lakes contain char and trout.
Summers are short, with temperatures ranging from 0°C to 20°C during late June to early September. Lake and river ice breaks-up in early July and lakes and rivers freeze in late September to early October. Weather becomes increasingly unpredictable in late summer and early autumn with fog, freezing rain, snow squalls and high gusty winds. The unpredictable weather increases stand-by time for helicopters and diamond drill rigs, and therefore affects exploration costs adversely, particularly in June and September. Ground work during the winter months is possible, but is largely restricted to ground geophysical surveys as insufficient daylight, extreme cold weather and lack of water hamper other kinds of work.
The properties are located immediately adjacent to claims currently held by Xstrata Nickel (formerly Falconbridge Limited), Canadian Royalties, Knight Resources/Anglo American, and Resolve Ventures (among others).

3. REGIONAL GEOLOGY
Regionally the GBK Raglan Project is underlain by rocks of the Cape Smith Belt, which extends for 375 km across the Ungava Peninsula of northwestern Quebec. The Cape Smith Belt is a thin-skinned foreland thrust belt that constitutes the northeast extension of the Trans-Hudson Orogen (known locally as the Ungava Orogen), an early Proterozoic collisional zone between the Archean Superior Craton and the Archean-Proterozoic Churchill Craton (Hynes and Francis, 1982; Hoffman, 1990). The Trans-Hudson Orogen also includes the Thompson Belt of Manitoba, which contains the productive Thompson Nickel Belt, and the Labrador Trough to the southeast of the Cape Smith Belt.
In the Goldbrook Raglan Project area, the Cape Smith Belt consists of two major Proterozoic units, the Povungnituk Group and the Chukotat Group (Bergeron, 1959). The Povungnituk Group consists of a lower sedimentary sequence (Lamarche and Dumas sub-groups; PPoi and PPosd), a middle volcanic sequence (Beauparlant sub-group; PPob and PPoga), and an upper sedimentary sequence (Nuvilik sub-group; PPos). The lower sequence consists of conglomerate, sandstone, iron formation, semipelite and dolomite in the base and sandstone, semipelite, pelite, minor basalt and mafic volcaniclastic sedimentary rocks in the top. The middle sequence of the Povungnituk Group consists of basalt, rhyolite and mafic volcaniclastic sedimentary rocks. The basalt is tholeiitic with continental affinity (Hynes and Francis, 1982). The upper sequence of the Povungnituk consists of sandstone and shale with minor basalt. The Povungnituk Group represents a continental rifting sequence.
The Chukotat Group (Bergeron, 1959) consists of massive and pillowed basalt, hypabyssal ultramafic and mafic intrusions, and discrete and interflow sedimentary rock units. The basalt ranges in composition from Mg-rich olivine-phyric komatiitic basalt at the base through pyroxene-phyric to plagioclase-phyic tholeiitic n-MORB equivalents at the top. The basalts are of oceanic affinity (Hynes and Francis,
10 GOLDBROOK VENTURES INC. Geological Mapping & Prospecting 2007
1982) and record the change from continental rift volcanism to oceanic crust volcanism (Francis et al., 1983; Picard et al., 1990).
Pre-tectonic mafic and ultramafic sills of gabbro, pyroxenite and peridotite intrude the Povungnituk and Chukotat sequences along and adjacent to major structures and fed the overlying basalts. The intrusions within the upper Povungnituk and lower Chukotat host nickel-copper-PGE sulfide deposits, as described in the following section. Regional structure is dominated by east-west oriented fabric. The oldest structures are south verging, east-west striking D1 and D2 thrust faults, which splay off a basal décollement at the Archean basement—Proterozoic cover interface (St-Onge and Lucas, 1990, 1993). All the rock sequences and stratigraphic groups are bound by thrust faults. The Cape Smith Belt was subsequently deformed by east-west trending D3 folds and north-northwest trending D4 folds during the Hudsonian Orogeny.
4. MINERAL DEPOSIT TYPES
The ultramafic bodies of the Cape Smith Belt host many Ni-Cu-PGE (nickel- copper-platinum group element) sulfide deposits (Avramtchev, 1982; Naldrett, 1989; Barnes et al., 1992). These deposits are of three types (Lamothe, 1986; Giovenazzo et al., 1989; Giovenazzo, 1991): 1) magmatic segregation deposits of massive to disseminated sulfides located at the base of ultramafic units; 2) stratiform, disseminated sulfide deposits ("reefs") located within layered, differentiated mafic-ultramafic sills; and 3) remobilized sulfides in shear zones. The Ni-Cu-PGE mineralization occurs mainly within two currently defined geologic horizons (Giovenazzo et al., 1989; St-Onge and Lucas, 1993). The first is the Raglan (or north) horizon, located at the base of the Chukotat Group (Fig. 2) and host of many of the known economic nickel deposits in the Cape Smith Belt. The second defined favourable horizon is the Delta (or south) horizon, located within the Povungnituk Group. Ultramafic intrusions hosting nickel sulfide showings also
11 GOLDBROOK VENTURES INC. Geological Mapping & Prospecting 2007 occur elsewhere within the Povungnituk (Avramtchev, 1982). A third horizon, the Rinfret horizon, is located to the north of the Raglan horizon, and is underexplored.
The Raglan horizon consists of a series of mafic-ultramafic bodies traceable along a strike length of 85 km. These units have been variously interpreted to be subvolcanic sills (Barnes et al., 1982) or channelized komatiitic basalt flows with peridotite (olivine cumulate) zones up to 150 metres thick (Barnes and Barnes, 1990; Lesher and Charland, 1999) within the upper sequence of the Povungnituk Group. Nine major magmatic segregation deposits have been discovered along the Raglan horizon, located at the base of host ultramafic units. These deposits from east to west are: Donaldson, Boundary, Zone 13-14, Zone 5-8, Katinniq, Zone 2, Zone 3, East Lake and Cross Lake (Fig. 2). The ultramafic units hosting mineralization contain pervasive sulfides, mainly 1%-3% finely disseminated to blebby pyrrhotite and pentlandite. The ore lenses vary considerably in size and shape, and are generally situated in footwall embayments at the base of the peridotite zones. Individual ore lenses consist of narrow zones of massive sulfide (up to a tens of metres thick with strike lengths of up to 200 metres), located along the footwall contact. Massive sulfides are overlain by net-textured and disseminated sulfides. Cobalt and platinum-group elements (PGE) are associated with the Fe-Ni sulfides.
The Katinniq deposit, currently mined by Xstrata Nickel (formerly Falconbridge Ltd. New Quebec Raglan Mines Inc.), consists of >20 discrete mineralized lenses (Chisholm et al., 1999). The lenses vary in size from 10,000 tonnes to 1.4 million tonnes, with diluted nickel grades of 2.5% to 5.0% Ni (Falconbridge Ltd., 2002). Altogether, the deposits along the Raglan horizon form an aggregate Reserve (proven and probable) of 18.1 million tonnes of 2.9% Ni and 0.8% Cu, in addition to an aggregate Resource (measured and indicated) of 2.88 million tonnes grading 2.0% Ni and 0.7% Cu.
12 GOLDBROOK VENTURES INC. Geological Mapping & Prospecting 2007
The Delta horizon occurs within the central part of the Povungnituk Group and consists of a series of mafic-ultramafic sills and dikes (Fig. 2). The Delta horizon hosts numerous nickel sulfide deposits, such as Delta (Xstrata Nickel) and Expo- Ungava, Mesamax, Ivakkak and Allammaq (Canadian Royalties). The Delta deposit is hosted by a gabbro-peridotite sill and includes all three types of mineralization noted above (Giovenazzo, 1991). The Expo-Ungava and Mesamax deposits are hosted by discordant gabbro-peridotite bodies and could be magmatic segregation deposits.
5. GBK PROSPECTING AND MAPPING PROGRAM 2007
The 2007 field program strategy was to revisit the entire Belanger Horizon from Kozmo to Delta, as well as to reassess NovaWest's interpretations and conclusions of the Bravo claim block. Geologists Michal Russer, David Clark, Matt Liard, Dominic Lussier and prospector Sebastien Allard shared the task of mapping and prospecting the Delta-Belanger properties in the summer of 2007. Thirteen areas were the focus for geological mapping and sampling, including Bravo West, Bravo East, Delta South, Delta East, Echo, Hellcat, Kozmo, Pillow Lake, East Pillow, PAD, R2, SuperFortress and Timtu. The target areas were variably mapped and sampled (Appendix 1 and 2). Geological stations were made at 361 separate locations, and 93 grab samples were sent in for geochemical analyses to ACCURASSAY Laboratories in Thunder Bay, Ontario for base and precious metal analysis. A news release was submitted on the 14th September 2004 describing the assay results for 21 of these samples (Appendix 4).
