Donner Metals Ltd.: Bracemac Yields Additional Results With New Mineralization Identified at the Productive Key Tuffite Horizon Below the Bracemac Zones

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 6, 2007) - Mr. Harvey Keats, Chief Executive Officer of Donner Metals Ltd. (TSX VENTURE:DON)(FRANKFURT:D4M), announces new results from the Bracemac Area on the Matagami Project, Quebec, and a new discovery of massive sulphide at the Key Tuffite Horizon below the Upper Bracemac/Bracemac Zones.

In the Upper Bracemac Zone, BRC-07-35 intersected two massive sulphide intervals grading 36.70% zinc and 0.05% copper over 0.65 metres and 10.70% zinc and 0.41% copper over 2.8 metres. BRC-07-39 intersected 3.5 metres grading 9.02% zinc and 0.56% copper. The intersections are 60 and 103 metres vertically below surface respectively.

Additionally, a drill test below the Bracemac Zones intersected the first indication of significant mineralization at the Key Tuffite horizon where BRC-07-38 intersected mineralized Key Tuffite over 2.6 metres, including a massive and semi-massive interval that graded 11.41% zinc and 0.26% copper over 1.3 metres, 230 metres below surface.

Reported results show a continued trend of mineralization towards surface in the Upper Bracemac Zone while delineation of the Bracemac Zone suggests an elongate trend that extends down-dip and down-plunge. Drilling is continuing where practical during break-up.

The intersection of massive sulphides at the Key Tuffite Horizon below Bracemac and Upper Bracemac is significant because it is a positive indicator of vertically stacked mineralizing activity at three levels, including the Key Tuffite horizon that hosts the majority of the deposits in the Matagami Camp. It is important to note that vertically stacked horizons can be exploited by single development infrastructure, providing a significant savings in development costs.

The Company's strategy is to explore for and discover Zinc - Copper deposits in the Matagami Camp and to leverage 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. Donner has discovered new mineralization at the Bracemac and Upper Bracemac levels and now reports an additional discovery in the Key Tuffite immediately below the Bracemac Zone discoveries.

Work completed since the last press release (April 3, 2007) includes the completion of seven drill holes and one hole deepening in the Bracemac area leading up to break-up which has limited access to planned drill collar locations. A total of 20,500 metres have been drilled of the planned 45,000 metre drill program. Three drills are active on the Matagami property with two drills active at Bracemac and one drill active at McLeod where results will be forthcoming.

Bracemac Area

Delineation continues on both of the new discoveries in the Bracemac and Upper Bracemac Zones, as well as an investigation of the Key Tuffite in the Bracemac area. Break-up has limited access to some planned drill set-ups and these holes will be drilled once surface conditions improve.

The sulphide intersections in diamond drill hole BRC-07-35 and BRC-07-39 continue to expand the Upper Bracemac Zone that extends 125 metres along plunge, trending towards surface, with a lateral extent of 50 to 60 metres. Drill hole BRC-07-35 was drilled 35 metres up-dip and to the east of drill hole BRC-07-31 that intersected 12.13% zinc and 0.7% copper over 9.3 metres. Drill hole BRC-07-39 was drilled 50 metres east and up-dip from drill hole BRC-07-30 that intersected 10.08% zinc, 0.49% copper over 2.3 metres and 25 metres down-dip of BRC 07-31 described above. BRC-07-33 was drilled 50 metres due east of BRC-07-31 and BRC-07-37 was drilled a further 100 metres due east of BRC-07-33.

In the Bracemac Zone, drill hole BRC-07-36 intersected 0.91% copper over 4.75 metres. This hole was drilled 60 metres to the west and down-dip of BRC-07-32 that returned 1.98% copper and 2.99% zinc over 21.25 metres. All of the drill holes designed to test the Upper Bracemac Zone also tested the up-dip portion of the Bracemac Zone where the extent of mineralization is now limited. The Bracemac Zone remains open down-dip, and down-plunge as well as to the east and west of known mineralization. Presently, the Bracemac Zone extends over approximately 200 metres in the plunge extent and between 20 and 100 metres in the lateral extent.

A significant mineralized interval at the Key Tuffite was discovered by BRC-07-38 that intersected 11.41% zinc and 0.26% copper at a vertical depth of 230 metres. This intersection occurs immediately below mineralization in the Bracemac zones and is open in all directions. In addition, BRC-86-4 EXT-W was drilled to test the Key Tuffite at a vertical depth of 900 metres and intersected weak mineralization at the targeted horizon.

West Camp

Three reconnaissance holes were drilled 50 kilometers west of Matagami to test Mag and EM (VTEM) geophysical anomalies in an area with geological potential to contain Matagami-type VMS Mineralization. Two of the three holes intersected weakly mineralized graphitic sediments (pyrite and pyrrhotite) within a sequence of felsic volcanic rocks. The third hole intersected weakly mineralized felsic volcanic rocks (pyrrhotite).

About the Matagami Project

The Matagami Project has an area of mutual interest of 4,737 square kilometres and presently includes 2,138 mineral claims covering 499 square kilometres. Taking advantage of Xstrata Zinc's extensive historical database, Donner and Xstrata Zinc Canada (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 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 2,350 t/day mill owned by Xstrata Zinc.

Throughout the Camp, mineralization occurs as bedded and pinnacle sulphides at the Key Tuffite (e.g. Matagami and Bell Allard Deposits) as well as vertical cone-shaped sulphide bodies hosted within the "Alteration Pipe" that occurs immediately below the Key Tuffite (e.g. Perseverance). Multiple, stacked mineralized zones and associated alteration pipes are now demonstrated (e.g. Bracemac). "Alteration Pipes" are identified by two styles of alteration; strong chlorite developed proximal to the hydrothermal vents and "Pipe style" characterized by intense chlorite with quartz stringers and local talc indicating the core of the hydrothermal vent system.

Donner has the option to earn a 50% participating joint venture interest in the Matagami Project by incurring a total of $20 million of expenditures on exploration and related work on or before May 31, 2011. Upon the expenditure of $20 million 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 such area by incurring up to $20 million on a feasibility study.
