VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 30, 2008) - Mr. Harvey Keats, Chief Executive Officer of Donner Metals Ltd. (TSX VENTURE:DON)(FRANKFURT:D4M), reports the expansion of the Bracemac Key Tuffite and McLeod zones at the Company's Matagami Project in central Quebec. At the Bracemac Key Tuffite Zone, diamond drill hole BRC-08-75, intersected massive and semi-massive sulphides down-dip of this zone that returned 7.75 metres averaging 3.79% copper and 5.61% zinc. The Old McLeod Zone, approximately 1 kilometre east of Bracemac, has been extended up-dip by MC-08-55 that returned 11.90 metres averaging 2.26% copper and 7.77% zinc. Drilling up-dip of the New McLeod Zone returned 1.04% Cu, and 13.16% Zn over 2.51 metres in MC-08-47. The West McLeod Zone, located between the Old McLeod Zone and Bracemac Key Tuffite Zone, returned significant copper mineralization in two drill holes, MC-08-46, averaging 4.12% copper over 15.65 metres and 3.02% copper over 5.32 metres, and MC-08-53, averaging 2.96% copper over 7.91 metres.

Bracemac Area
Bracemac Zone: Diamond drill holes BRC-08-75 and BRC-08-76, engineered to target the Key Tuffite horizon, also tested the Bracemac horizon east of known mineralization and intersected heavily disseminated and semi-massive sulphides over thin intervals underlain by strong chlorite alteration. BRC-08-75 intersected the horizon 20 metres east and up-dip of BRC-08-74 and 20 metres down-dip from BRC-07-34, both of which did not intersect mineralization at the Bracemac horizon. BRC-08-76 was drilled 50 metres down-dip and to the east of BRC-07-28 (9.83% Zn, 0.90% Cu, 13.3 g/t Ag, 0.18 g/t Au over 6.90 metres) and 55 metres east of MC-06-27 (13.98% Zn, 3.69% Cu, 38.9 g/t Ag, 0.48 g/t Au over 8.80 metres). BRC-08-77, also targeting the underlying Key Tuffite level, intersected the Bracemac Tuffite 25 metres down-dip from BRC-08-75 and did not encounter mineralization or alteration.
Bracemac Key Tuffite Zone: Drill hole BRC-08-75 extended mineralization 95 metres down-dip from BRC-08-74 (11.46% Zn, 5.63% Cu, 17.73% Ag, 1.47 g/t Au over 23.70 metres) where it intersected massive, semi-massive and stringer sulphides within a thick interval of intense Pipe alteration. BRC-08-76 intersected unmineralized Key Tuffite followed by intense Pipe alteration 40 metres down-dip and to the west of BRC-08-74 and 60 metres west and up-dip from BRC-08-75. Drill hole BRC-07-28 was extended to the Key Tuffite where it intersected unmineralized tuffite 60 metres west and slightly up-dip from BRC-08-74. BRC-06-26 was also extended and intersected unmineralized Key Tuffite followed by chlorite alteration 75 metres west of BRC-08-76. Diamond drill hole BRC-08-77 intersected unmineralized, brecciated Key Tuffite, underlain by Pipe alteration 60 metres east and up-dip from BRC-08-74. Drill hole BRC-08-80 intersected weakly mineralized Key Tuffite, 100 metres east of BRC-07-61 (9.48% Zn, 2.81% Cu, 26.74 g/t Ag, 0.37 g/t Au over 6.00 metres). Mineralization and/or intense Pipe alteration encountered in drill holes BRC-08-74, BRC-08-75, BRC-08-76 and BRC-08-77 warrants continued drill investigation in this area of the Bracemac Key Tuffite Zone. The zone remains open down-dip.
Two widely spaced step-out drill holes investigated the up-dip extension of the Bracemac Key Tuffite Zone. BRC-08-78 intersected weakly mineralized Key Tuffite 225 metres up-dip and west of known mineralization at a depth of 50 metres. BRC-08-79 tested the Key Tuffite 75 metres up-dip from BRC-08-71 (3.53% Zn, 0.33% Cu, 10.56 g/t Ag, 0.08 g/t Au over 8.40 metres) where it encountered a gabbro sill, occupying the Key Tuffite stratigraphic interval.
McLeod Area
New McLeod Zone: Two drill holes were completed up-dip of the New McLeod Zone. MC-08-47 investigated the up-dip extension of the central portion of the zone and intersected high-grade mineralization 65 metres up-dip from MC-07-22 (19.30% Zn, 1.32% Cu, 28.5 g/t Ag, 0.75 g/t Au over 5.04 metres) and 40 metres down dip of MC-07-25 (35.6% Zn, 1.82% Cu, 54.9 g/t Ag, 2.93 g/t Au over 0.96 metres). Drill hole MC-08-51 intersected stringer mineralization 55 metres up-dip and to the east of MC-08-43 (13.98% Zn, 1.15% Cu, 30.03 g/t Ag, 0.94 g/t Au over 8.54 metres) and 50 metres west and up-dip of MC-07-25. Drilling continues to investigate a link between mineralization in the New McLeod and Old McLeod Zones.
Old McLeod: Two drill holes were completed in the Old McLeod Zone. MC-08-52, drilled 80 metres up-dip from MC-07-27 (18.45% Zn, 2.11% Cu, 42.83 g/t Ag, 1.12 g/t Au over 9.80 metres and 10.51% Zn, 3.94% Cu, 92.38 g/t Ag, 0.85 g/t Au over 3.22 metres) encountered weakly mineralized Key Tuffite. BRC-08-55 was drilled 50 metres up-dip from MC-07-27 and 45 metres west of MC-08-52 where it intersected high-grade mineralization related to an off-hole EM anomaly detected in MC-08-52. The Zone is open up-dip from MC-08-55 and its extent remains to be delineated.
Old McLeod, Up-dip: Drill hole MC-08-49 intersected unmineralized, brecciated Key Tuffite underlain by intense chlorite alteration 45 metres west and down-dip from MC-08-45 (8.09% Zn, 2.35% Cu, 5.64 g/t Ag, 0.26 g/t Au over 6.35 metres). MC-08-50 was drilled 125 metres west of M6 (1.7% Zn, 4.21% Cu over 6.95 metres) and intersected weakly mineralized Key Tuffite underlain by Pipe alteration. This hole also intersected pipe alteration stratigraphically above the Key Tuffite horizon at approximately the same stratigraphic position as MC-08-36 (18.10% Zn, 3.14% Cu, 61.28 g/t Ag 1.37 g/t Au over 4.18 metres) drilled 130 metres to the west and up-dip of MC-08-50.
West McLeod Zone: Assay results for drill hole MC-08-46 (previously described in News Release dated May 27, 2008) were returned and yielded high-grade copper over 15.65 metres and 5.32 metres. This hole was drilled at an orientation 90 degrees to the standard drill hole direction to test for vertical, northeast - southwest structures that trend parallel to the standard drill orientation. Pipe alteration, locally mineralized, has been observed at and below the Key Tuffite in previous drilling in the West McLeod Zone and is thought to be controlled by these structures. MC-08-46 undercut the area between MC-07-30W1 (0.89% Zn, 2.77% Cu, 12.23 g/t Ag, 0.05 g/t Au over 2.24 metres) and MC-07-21 (traces of chalcopyrite associated with chloritized structures). Mineralization is hosted within Pipe alteration at and immediately below the Key Tuffite horizon. MC-08-46W1 is a wedge cut up-dip and slightly west of MC-08-46 where it intersected weakly mineralized Key Tuffite followed by weakly mineralized Pipe alteration in the footwall to the Key Tuffite. The true width and the geometry of the sulphides encountered in MC-08-46 remain uncertain and will require continued drill follow-up.
MC-08-53 was drilled between the Old McLeod Zone and the West McLeod Zone where it intersected substantial copper mineralization in Pipe alteration in the immediate footwall to the Key Tuffite. Mineralization is similar to copper-rich sulphides encountered in MC-08-46 and may suggest a link between the Old McLeod Zone and the West McLeod Zone.
Details of the assay results can be found in the attached Appendix 1. Four drills are active on the Matagami Project at Bracemac and McLeod. A total of 70,278 metres of diamond drilling in 145 drill holes has been reported on since the project began in late 2006. Additional geological information, including maps and sections, is available at www.donnermetals.com.
The Matagami Project has an area of mutual interest of 4,750 square kilometres and presently includes 3,340 mineral claims covering 801 square kilometres. Taking advantage of Xstrata Zinc's extensive historical database, Donner and Xstrata Canada Corporation - Xstrata Zinc Canada Division (Xstrata Zinc) are using a combination of 3D data integration, innovative advanced technologies, new concepts and diamond drilling to explore for new deposits in this prolific mining camp.
The Matagami Mining Camp is a world-class mining district, with 18 known VMS deposits, including 10 past producers of varying sizes, including the giant Matagami Lake Deposit (25.64 million tonnes of 8.2% Zn, 0.56% Cu, 20.91 g/t Ag and 0.41 g/t Au) discovered in 1957 and mined from 1963 to 1988. The area is host to historical production of 8.6 billion pounds of Zn and 853 million pounds of Cu and has established infrastructure including the town of Matagami, a railway, a paved road, and a 2,600 t/day mill owned by Xstrata Zinc.
Donner has the option to earn a 50% participating joint venture interest in the Matagami Project by incurring a total of $20 to $25 million of expenditures on exploration and related work on or before May 31, 2011. Upon earn-in by Donner, five separate joint ventures will be formed, covering the property and the area of interest. In each of the five joint venture areas, Xstrata Zinc has the option to earn back a 15% interest in each area by incurring up to $20 million on a feasibility study.
The Company's strategy is to explore for and discover zinc - copper deposits in the Matagami Camp and to leverage the general infrastructure and existing processing facilities within a known and well-established cost structure for developing VMS deposits. Donner's exploration objective is to investigate multiple stratigraphic horizons with potential for VMS mineralization including the prolific Key Tuffite horizon throughout the Matagami Camp. To date Donner has discovered new mineralization at Bracemac in the Upper Bracemac and Bracemac zones and the Key Tuffite horizon. In addition to delineation drilling at Old McLeod, Donner has discovered new mineralization at New McLeod and West McLeod at the Key Tuffite horizon at McLeod.
