(TSXV:BLV BLV bovine leukemia virus. ) (Blackstone) entered into an Option and Joint Venture agreement on August 15, 2003, to explore the Espedalen nickel project in Norway. The project is located approximately 180 km north-north-west of Oslo. Blackstone can earn a 60% interest in the property by funding $2.25 million in expenditures by September 30, 2007. Sulfidmalm has the option to back in up to 75% in stages. It can reach 60% in the property by incurring 220% of Blackstone's expenditures, a further 10% by completing a Feasibility Study "A Feasibility Study" is an episode of the original The Outer Limits television show. It first aired on 13 April, 1964, during the first season. It was remade in 1997 as part of the revived The Outer Limits series with a minor title change. and a further 5% by providing loan guarantees for production financing. Sulfidmalm agreed to take subscriptions in Blackstone equal to 25% of the first year's program, 20% of the second year, 15% of the third year and 10% of the fourth year. Sulfidmalm is the Operator of the project. Highlights of the 2004 exploration program at Espedalen include: - Drill intercepts of significant nickel mineralization at the Stormyra Discovery where two drill holes spaced 200 metres apart intersected 6.91% nickel over 1.9 metres within a 14.6 metre intersection grading 1.73% nickel; and 2.07% nickel over 2.7 metres. Only two holes have been drilled on this zone and it is open in all directions. - Extension of the conductor associated with Stormyra to the south, indicating a total conductor strike-length of 1,100 metres. - 15 drill-holes completed on the entire property, testing 11 conductors; 13 of the drill holes intersected nickel-bearing sulphide mineralization. - 12 new geophysical ge·o·phys·ics n.

Background The Espedalen area is a historical copper and nickel mining area having produced copper from 1666 to 1750 and nickel from 1848 to 1878. Indeed, the Espedalen project area could be considered the birthplace of nickel sulphide mining. The mining operations ceased production due to poor metal prices as the result of the development of the laterite laterite Soil layer rich in iron oxide and sometimes aluminum, derived from a wide variety of rocks by leaching. It forms in tropical and subtropical regions where the climate is humid. nickel deposits in New Caledonia New Caledonia, Fr.

Small stockpiles of "ore" (direct shipping and low grade) are still present on the property. Mineralization occurs within a detached portion of the Jotun Nappe nappe In geology, a large body or sheet of rock that has been moved by faulting or folding a distance of about 1 mi (1.5 km) or more from its original position. A nappe may be the hanging wall of a low-angle thrust fault (a fracture in the rocks of the Earth's crust caused Complex, which is a large (100 x 200 km) dominantly Precambrian thrust block that overlies non-detached Precambrian Gneisses and Lower Paleozoic rocks. It is composed of metamorphosed syenites, norites, anorthosites, gabbros, pyroxenites and peridotites. Cross-cutting relationships suggest multiple periods of intrusion from 1698 Ma for the oldest syenites to 1250 Ma for the youngest gabbros. The nappe was emplaced in its current position during the Caledonide Orogeny orogeny Mountain-building event, generally one that occurs in a geosyncline. Orogeny tends to occur during a relatively short geologic time frame. It is usually accompanied by folding and faulting of strata and by the deposition of sediments in areas adjacent to the orogenic during the Mesozoic period. The original position of the unit is interpreted to have been west of the current Norwegian coastline. Reconstructions place this position close to the east coast of Labrador. The similarity in the types and ages of the rocks supports such a possible connection. The Espedalen area is underlain un·der·lain v.

In the mid 1960s, Sulfidmalm conducted some reconnaissance prospecting and geophysical surveys Geophysical survey refers to the systematic collection of geophysical data for spatial studies. Geophysical surveys may use a great variety of sensing instruments, and data may be collected from above or below the Earth's surface or from aerial or marine platforms. in the Espedalen area.

All holes hit low grade disseminated sulphides and the highest grades were encountered on the Megrundstjern Grid (27.4 metre of 0.60% Ni, 0.16% Cu). From 1975 to 1977, 38 holes totaling 3,186 metres (84 metre average) were drilled to test geophysical anomalies.

Sulfidmalm, initially acquired 150 preclaims, totaling 45 square km, over the Espedalen area in January 2003. An additional 158 preclaims, totaling 43.45 square km, have subsequently been added bringing the current property position to 308 preclaims, totaling 88.45 square km. In early 2003, a 28 km UTEM program was completed over a portion of the southwestern part of the property where Sulfidmalm had conducted most of their previous work. Results included the identification of two good to excellent quality conductors that merited drill testing.

Following the signing of the Sulfidmalm-Blackstone agreement, a 932 line km Hummingbird hummingbird, common name for members of the family Trochilidae, small, strictly New World birds, related to the swifts, and found chiefly in the mountains of South America. Hummingbirds vary in size from a 2 1-4-in. AEM AEM Applied and Environmental Microbiology (journal) AEM Association of Equipment Manufacturers AEM Academic Emergency Medicine (journal) AEM Agnico-Eagle Mines Limited AEM Advanced Engine Management survey was flown during October 2003. The depth penetration of this system is thought to be around 50 metres. The survey identified nine high priority conductors and eight secondary conductors while the magnetics demonstrated that the ultramafic ul·tra·maf·ic adj.

Dunite is an ultramafic rock. units were more extensive than previously thought. From February to March 2004, a 123 km UTEM survey was completed over these newly detected conductors and the historical workings on the northeastern part of the property. This resulted in the identification of 29 conductors of interest, including eight high priority conductors. Field ground check of conductors and limited mapping were completed in the summer. A diamond-drill program consisting of 1,842 metres in 18 drill-holes (3 holes were abandoned due to drill equipment difficulties) testing 11 of 29 prospective EM conductors was completed from July to September 2004. All but two of the completed holes intersected Ni bearing sulphide mineralization, indicating the effectiveness of the geophysical methods. Please refer to maps provided at www.falconbridge.com for drill-hole locations. A significant result of this program was the discovery of the Stormyra nickel mineralization on the P2-P2a conductor (6.91% Ni over 1.9 m). The discovery is within a swampy area with little bedrock exposure in the southwestern part of the property. It is located at the southern limit of the 2003 AEM survey and subsequently AEM coverage was extended in this area in October 2004. The combined results of these surveys indicate that the conductor associated with Stormyra has a strike length of 1.2 km. The new geophysical survey also identified 12 other conductors in the southern and eastern property area that will require follow-up work. The conductor at Stormyra has been modeled as a shallow dipping plate that is approximately parallel with foliation foliation Planar arrangement of structural or textural features in any rock type, but particularly that resulting from the alignment of constituent mineral grains of a metamorphic rock along straight or wavy planes. and lithological contacts, as observed in the drill holes and therefore, the thickness of the mineralized intercepts are interpreted to be close to true thickness. The Stormyra mineralization is open to expansion in all directions. Three of the other drilled conductors are identified as priorities for follow-up work. An example is the Dalen area (P4 conductor) where drilling intersected 34.4 metres grading 0.45% nickel on the northern edge of a UTEM conductor. The UTEM conductor is associated with a large magnetic feature that trends to the southeast under Espedalen Lake and has not been fully covered by UTEM.

Renaissance Zinc - Copper Project, Matagami, Quebec Matagami is a small town in Quebec, Canada, part of the Baie-James Municipality. It is located north of Amos, on Matagami Lake, and marks the start of the Route de la Baie James (James Bay Road). Matagami was founded in 1963 with the development of mining in the area. In a press release dated October 26, 2004, Noranda announced that one of its exploration drilling programs in northern Quebec intersected a new zone of massive sulphides at moderate depths on one of its wholly-owned properties near Matagami, Quebec. The Renaissance showing is located within the Matagami mining camp South Flank stratigraphy stratigraphy, branch of geology specifically concerned with the arrangement of layered rocks (see stratification). Stratigraphy is based on the law of superposition, which states that in a normal sequence of rock layers the youngest is on top and the oldest on the , approximately 7 km southeast of Noranda's Matagami milling infrastructure. This release provides an update on exploration activities at the Renaissance project, in the Matagami camp. A drill hole plan and section, plus details of assay intervals, are available on the Noranda website at www.noranda.com. The sulphide zone reported in hole MC-04-07 ran a length weighted 14.81% Zn, 1.65% Cu, 36.4 g/t Ag and 0.68 g/t Au over 9.5 metres core length from 527.25 to 536.75 metres. Estimated true width of this portion of the intercept is approximately 7.3 metres, with the mid-point centred at approximately 465 metres vertical depth. The massive to semi-massive portion of the zone is followed by mineralized exhalite, and stringer string·er n. 1. One that strings: a stringer of beads. 2. Architecture a.

An extended intercept to the end of this mineralization returned a length weighted 11.15% Zn, 2.04% Cu, 41.9 g/t Ag and 0.61 g/Au over 14.05 metres. Estimated total true width is approximately 10.8 metres. Since the discovery a total of six new holes (MC-04-08 to MC-04-13) have been drilled on the Renaissance showing. This drilling has focussed on rapidly delineating the possible extents of the mineralized zone at wide-spaced centres. Summary descriptions of this drilling are presented below; diagrams illustrating the Renaissance drill program in plan and longitudinal views are posted on the Noranda website (www.noranda.com).

While the results of the 2004 drill program have limited the extents and tonnage potential of the Renaissance showing, it should be noted that all Matagami deposits are known to have satellite lenses. Future work will concentrate on wider-spaced step-out drilling that will target the favourable synvolcanic fault structure that is host to the Renaissance showing, and sectors previously untested by diamond drilling. Quality Control Drill programs in Matagami are supervised by Grant Arnold (Geology Superintendent - Noranda Inc.) who is a Qualified Person under National Instrument 43-101 guidelines.

The secondary lab was ACME in Santiago, Chile Santiago, officially Santiago de Chile (Spanish: (helpinfo)), is the capital of Chile, and the center of its largest conurbation (Greater Santiago). . The analytical method used was multi-acid digestion, atomic absorption assay analysis for copper and molybdenum. Noranda's Drill Core Sampling and Analysis Protocols, a rigorous protocol procedure developed internally for all advanced drill programs, has been employed throughout the drill program to ensure quality assurance and quality control. The sampling protocol specifies that assay samples are taken from drill core (NQ size) sawed in half with one half sent to a commercial laboratory and the other half retained for future reference. Additionally, the insertion of three project specific standards and blank samples, has been part of all Project activities. The results for the analysis of samples collected by Noranda were considered to be within the required standards for Noranda's protocols although Mo was less precise than Cu, partly because Mo values were frequently near the detection limit. However, as there was a significant amount of drilling prior to Noranda's involvement it is important to the resource estimate to note that the QAQC QAQC Quality Assurance/Quality Control QAQC Quality Assurance/Quality Checks (US DoD) procedures in assaying were variable prior to Noranda's involvement in the project (holes up to P-237). A major re-assaying program was undertaken (on pulps, rejects or remaining core, depending on available material) with proper QAQC procedures in order to compare previous assays with those of the latest campaigns. This resulted in a slight increase in total metal in the resource but the average grade did not change, probably due to the smoothing effect of kriging. The Mo re-assaying failed to identify any biases in the datasets because of highly variable original assays but this exercise at least provides a better assessment of the distribution of Mo within the deposit.

Strong potassic alteration accompanied the main stage of mineralization, and is locally overprinted by phyllic and intermediate to advanced argillic assemblages. An 8,000 metre diamond drill program is in progress on the La Fortuna zone. The in-fill drilling is designed to explore the extent and distribution of higher-grade supergene copper mineralization, and the distribution and geologic controls of potentially higher-grade gold zones. Successful outcome would allow those zones to be more accurately modeled in the resource estimates. Drilling is not planned elsewhere on the property. Quality Control ALS Bondar Clegg, of Coquimbo, Chile, using Gannet certified standards, has completed all of Noranda's analytical work on the project to date. The analytical method used is geochemical analysis for copper and fire assay with an atomic absorption finish for the gold values. Noranda's Drill Core Sampling and Analysis Protocols, a rigorous protocol procedure developed internally for all advanced drill programs, has been employed throughout the drill program to ensure quality assurance and quality control. The sampling protocol specifies that assay samples are taken from drill core (HQ and NQ size) sawed in half with one half sent to a commercial laboratory and the other half retained for future reference. Additionally, the insertion of project specific standards and blank samples, has been part of part of all Project activities. Sampling protocols and procedures for all historic holes, not drilled by Noranda, are not known.

Exploration work consisted of nearly 6,500 metres of diamond drilling along with engineering concept studies to examine conceptual process, potential mining scenarios and infrastructure design. A total of 32 holes were completed on December 17, 2004 on four target areas at Nena North, Nena West, Nena South and North Debom. Drilling at Nena West and Nena South is targeting possible extensions to the established Nena resource. Within both these targets, drilling has intersected high grade enriched secondary copper. To date assays have been received for all but part of hole 044NOR04. Significant results are summarized in the table below.

Nena-style mineralization has also been discovered 1.5 km to the south at North Debom in drillhole 027NOR04 which produced an intersection of 1.22% Cu over 32 metres including intervals of 2.65% Cu over 6m and 2.30% Cu over 6 metres. Assays are pending on the second hole to intersect the mineralized zone. Once the current drilling program is complete, the results will be consolidated into an ongoing compilation of historical geological information which will be used as the basis for a new interpretation of the geology of the deposit in advance of a revised resource estimate scheduled for completion in the first half of 2005. Recommendations for future work include a 9,900 metre drilling program in 2005 that will comprise: - 5,400 metres of drilling to: - Delineate the Nena deposit; - Investigate the extensions of the North Debom deposit; and - Test the Hiro ridge, mineralized breccia target. - 3,000 metres of drilling on the Ekwai Debom high sulphidation target and on porphyry targets; and - 1,500 metres of PQ drilling for metallurgical sampling. Once the Nena deposit has been completely defined, a revised resource estimation will be undertaken that will include all the results of the 2004 drilling program. A metallurgical sampling program comprising approximately 1,500 metres of PQ drilling will be undertaken on the Nena deposit to investigate the predictive metallurgy metallurgy (mĕt`əlûr'jē), science and technology of metals and their alloys. Modern metallurgical research is concerned with the preparation of radioactive metals, with obtaining metals economically from low-grade ores, with of this mineralization type for which previous studies indicated complex metallurgy. Diamond drilling is planned to resume in mid February 2005. Quality Control Quality assurance procedures were adopted to ensure quality data were obtained for all measurements. All drill collars have been surveyed by a qualified land surveyor. Downhole attitude (dip and magnetic north) were measured with a single-shot photographic system. The drilling program is operated by Highlands Pacific, Noranda's partner at Frieda River, and supervised by an employee of Noranda Inc./Falconbridge Limited, project manager Charles Beaudry, P.Geo. and Qualified Person under National Instrument 43-101 guidelines. Mr. Beaudry spent 12 weeks in total at project site during the 2004 drilling program. All core is moved daily to a core logging and sample preparation facility established at the project site. Representative core samples are tested for density determinations using the immersion method after waxing. Core is logged (geology, geotech) by a geologist and photographed. Mineralized intervals are subdivided by a geologist on 2.0 metre composites and sawn in half with one half retained and the other sent to the sample preparation facility. Due to the reactive nature of the mineralization in the hot humid climate special precautions are taken to avoid oxidation: - Rapid processing of the samples on a daily basis; - Nitration of all samples prior to shipping; and - Nitration of rejects. The half sawn core samples are processed for assay according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2.

Notes: (greater than or equal to 90% passing -40mesh). A minimum of 200 g of pulp is scooped from the LM5 bowl and this material is sent to the lab for analysis/assay. Crushing and milling are monitored with sieve tests (5%) and with 10% duplicates. Blank material consisting of broken glass (from soft drink bottles) is inserted in 5% of samples, particularly after a run of high grade material. The pulp samples are sent to ALS in Townsville for gold fire-assay (50 g - Au-AA26), ICP-AES ICP-AES Inductively Coupled Plasma Atomic Emission Spectroscopy ICP-AES Inductively Coupled Plasma Atomic Emission Spectrophotometry (ME-ICP41s and ME-MS42) analysis for 36 elements including Cu, As, Sb, Hg, and Te and for sulphide S by difference (S-CAL07). All samples with copper values above the upper detection limit of 1% Cu are sent to ALS Brisbane for Cu assay by strong acid digestion and atomic absorption (Cu-OG46) determination. Standards are inserted in the batches in every 20th sample. Initially an internal project standard (Sierita) was utilized but when high grades were encountered in the Nena drilling three additional commercial standards were acquired to improve the monitoring of analytical performance for both copper and gold (GBM GBM 1 Glioblastoma multiforme, see there 2. Glomerular basement membrane 304-11 and 16 and G301-8). The standards are rotated and selected for the type of mineralization encountered in the core.

As a result, the high grade copper assays in the first half of the drilling program were mainly monitored from the extensive QAQC results published by ALS with the analytical reports. These data were reviewed and found to be acceptable. Except for one short period in the early part of the program the blanks performed very well. At least 10% of the pulp samples were submitted to Genalysis as a secondary lab for check analysis for Cu and Au. A slight bias of 5% in favour of ALS was observed in the assays ranging between 1% and 4% Cu. Higher and lower grade assays results showed no bias. Falconbridge Limited (TSX:FL) Noranda Inc.
