Disclosure Review
Friday, August 22, 2008
Vancouver, B.C.: Bell Copper Corporation ("Bell Copper" or the "Company") (TSX-V Symbol: BCU) reports that as a result of a review by the British Columbia Securities Commission, it is issuing the following news release to clarify its disclosure.
The Company has filed an independent technical report dated May 20, 2005, revised June 20, 2005 (the "Granduc report"). Portions of the Granduc report should not be relied on because it contains disclaimers of compliance for historical resource estimates and other information at the Granduc. All mineral resource estimates at Granduc are historical in nature and have not been adequately reviewed by a Qualified Person to be reported as current resources. They also lack original assay sheets, specific gravity determinations and quality control data, and must only be regarded as historical resources that cannot be relied upon by anyone. The historical resources at Granduc are to be used for geological purposes only. The economic analyses previously disclosed for Granduc in the Company's website and investor materials cannot be supported by any new technical report at this time.
The Company has made reference through its website and other materials to the results of internal economic analysis of both the Granduc and La Balsa projects not supported by a technical report. In response the Company retracts any reference made to any unsupported economic analysis of either the Granduc or the La Balsa projects and has removed any references from its website and materials.
The Company has reported mineral resources in a manner that is contrary to NI 43-101 for the Granduc and La Balsa projects. In response all references to the La Balsa mineral resource have been replaced by the resource table as contained in the Behre Dolbear NI43-101 Technical Report on the La Balsa project.
The Company specifically retracts the estimates of potential exploration targets at its Sombrero project of 10-20 million tonnes of 1.5% Cu to 2.5 % Cu ore in breccias, underlain by 200-300 million tonnes of 1.0% Cu-Mo ore in subjacent porphyry targets. The Company does not have drillhole or other information specific to this volume of rock that could satisfy the reporting requirements of s.2.3(2)(b) of NI 43-101, and it was based on a hypothetical ore deposit model unproven by any exploration to depth. The potential quantity and grade is conceptual in nature. There has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
Furthermore, the Company retracts a previously disclosed 40-150 million tonne estimate of a potential exploration target at Granduc because the known geology at Granduc makes this range of tonnages appear overly promotional. The potential exploration targets at Granduc are retracted and restated adopting a more conservative tonnage range that falls within the small to median tonnage of known Besshi-type deposits world-wide as published by the Geological Association of Canada (Slack, J.F., 1993, Descriptive and grade-tonnage models for Besshi-type massive sulfide deposits, in Kirkham, R. V., Sinclair, W.D., Thorpe, R.I., and Duke, J.M., eds., Mineral deposit modeling, GAC Special Paper 40, p. 343-372). The tonnage range that the Company is targeting in its exploration at Granduc will therefore be between 20 and 40 million tonnes. The grade range that the Company is targeting in its exploration at Granduc will be between 1.5% Cu and 2.5% Cu which is both within the range of previous drill intersections of the Granduc Mine Series rocks and is also within the range of recent exploration drilling results derived up to 800 meters south of and 2000 meters north of the historic resources at Granduc along what is reasonably inferred to be the same geological interval (the late-Triassic Granduc Mine Series) that hosts the historic resources. The potential quantity and grade referred to above is conceptual in nature. There has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
Geological and geophysical support for the Granduc exploration target size and quality comes from successful prospecting in areas of recent glacial retreat, from geophysical surveying, and from Diamond drilling. An airborne EM/magnetic survey flown in May 2005 showed linear high magnetic anomalies and high conductivity anomalies coincident with the Granduc Mine Series rocks, supporting the concept that this same stratigraphic package of magnetite-facies exhalite, massive sulfide, and graphitic argillite extends under ice nearly one kilometre south of and two kilometres north of the Granduc Mine. A former geologic theory which held that the Granduc Mine Series had been faulted away at the north end of the Granduc Mine has been shown to be erroneous by this survey and the subsequent discovery in 2006 of outcropping magnetite- and massive sulfide-exhalite further north in an area recently exposed by melting of the Granduc Mountain icefield. Subsequent Diamond drilling by the Company in 2005 and 2006 of 17 Diamond drillholes which targeted the along-strike continuation of the Granduc Mine Series rocks beneath the South Leduc glacier and the Granduc Mountain icefield demonstrated that the aeromagnetic and EM anomalies were indeed related to exhalative magnetite iron formation, massive sulfide, and interbedded graphitic argillite and tourmaline-bearing chert. The following table summarizes drill intersections from the Company's Diamond drilling campaigns in 2005 and 2006:

*Position is referenced to an imaginary coordinate system having an origin at the south end of historic mining at Granduc and oriented parallel to strike of the Granduc Mine Series rocks. Historic mining of 15 Mt of massive sulfide took place between 0m North and about 840m North.
Historic drilling conducted by Esso Minerals in 1983 and 1984 on very rough 120 meter centers between positions from 1300m North to 1600m North and 1740m North to 2170m North is reported to have cut massive sulfide intervals comparable in thickness and grade to the Company's drill intersections south of the mine. The unassayed halves of these core intervals were preserved in a core shed in Stewart and were personally inspected by Dr. Marsh, the Company's Qualified Person. These intervals represented typical massive sulfide and magnetite iron formation hosted by Granduc Mine Series rocks. Although gaps between drillholes are as great as 400 meters, more than one half of the drillholes that cut the projected Granduc Mine Series rocks north of the area of historic mining also cut massive sulfide mineralization. These historic intersections, together with the results from the Company's 2005 and 2006 drilling programs, support an exploration target that extends south of the area of historic production for at least 800 meters and north of the area of historic production for at least 1800 meters. Massive sulfide drill intersections span a vertical range of at least 300 meters south of the mine to nearly 500 meters north of the mine, and mean true thicknesses of massive sulfide are around 4 meters. Though drill intersections have not yet probed so deeply, no fundamental geological limitation has been encountered at depth to prevent massive sulfide mineralization north of the mine from extending to similar elevations south of the mine where massive sulfide has been demonstrated by drilling. Extension of massive sulfide another 400 meters deeper to sea level along the entire 4 kilometer extent of the Granduc Mine Series rocks would yield a target tonnage near 40 million tonnes. If massive sulfide mineralization is less blanketlike and more podiform in distribution, as some lean drill intersections suggest, the tonnage might be substantially lower. This line of reasoning supports an exploration target size at Granduc of 20 to 40 million tonnes of massive sulfide. Grades of this mineralization might be similar to those already intersected in the Company's Diamond drilling campaigns in 2005 and 2006, or in the range of 1.5% to 2.5% Cu. This potential quantity and grade of the Granduc exploration target is conceptual in nature. There has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource. All other references to potential numerical exploration targets have been removed from the Company's website and other materials.
