Donner Metals Ltd.: 6 New Massive Sulphide Intersections, Including 19.75
Metres of 22.95% Zinc, 21.40 Metres of 12.47% Zinc at Bracemac and 11.42 Metres
of 8.91% Zinc at McLeod

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 2, 2007) - Mr. Harvey Keats, Chief Executive Officer of Donner Metals Ltd. (TSX VENTURE:DON) reports significant results from delineation drilling at both Bracemac and McLeod. At Bracemac, high-grade massive sulphides have been intersected in three drill holes that tested the Key Tuffite Horizon, the horizon that hosts the major deposits of the Matagami mining camp. At McLeod, high-grade massive sulphides have been intersected in three drill holes, also at the Key Tuffite stratigraphic level. McLeod is located approximately 1 kilometre southeast of Bracemac which is located 4 kilometres southeast of Xstrata's Matagami mill.

A summary of important intersections reported in 2007 at both Bracemac and McLeod are presented in Table 2. Additional geological information, including maps and sections, on both areas is available at www.donnermetals.com. Twelve holes have been completed on the Matagami Project since the Company's news release dated June 14, 2007 for a total of 6310 metres of drilling. Three drills are active on the Matagami Project.
Bracemac
The two new intersections encountered in BRC-07-46 and BRC-07-47 indicate a substantial thickness of high grade massive sulphides at the Key Tuffite level. Encouragement was initially encountered at the Key Tuffite level in previously reported BRC-07-38 (11.41% zinc over 1.3 metres) (see News Release dated June 6, 2007) and in BRC-07-42 which intersected 9.09% zinc over 2.0 metres with an off-hole EM response that lead to the discovery of the thicker sulphide intervals in BRC-07-46 and 47. BRC-07-42 was drilled 100 metres east of BRC-07-38. BRC-07-46 was drilled 25 metres down-dip of BRC-07-42 and BRC-07-47 was drilled 50 metres due east of BRC-07-46. This new mineralization occurs stratigraphically below the massive sulphide mineralization in the Bracemac and Upper Bracemac Zones and confirms both the presence of three vertically stacked mineralized horizons and a robust VMS hydrothermal system in this area.
Drilling also continued to investigate the up-dip extension of the Upper Bracemac Zone with the drilling of BRC-07-41 which intersected unmineralized tuffite underlain by 18 metres of chlorite alteration and sulphide stringers.
The down-plunge and up-dip extension of the Bracemac Zone was investigated by drill holes BRC-07-43 and 44 respectively. Both holes limited the extension of massive sulphides, however very well developed pipe alteration with stringer sulphides over a width of 90 to 100 metres was encountered in both holes and suggests a very robust hydrothermal system can be further investigated for additional massive sulphides down plunge and to the east of the known massive sulphides.
Reconnaissance drilling that targeted magnetic and EM anomalies at the Key Tuffite elsewhere on the Bracemac property was conducted by drilling three widely spaced holes, BRC-07-40, 45 and 48. These holes did not return significant results.
McLeod Zone
One drill hole and two wedge holes were completed at McLeod targeting the well developed mineralization encountered earlier in the program at the Key Tuffite horizon. The two new wedge holes (MC-05-18W3 and W4) were drilled to follow up the results previously reported from diamond drill hole MC-05-18W2 that intersected 27.95 metres of 9.24% zinc, 0.99% copper, 26.1% silver and 0.56g/t gold (see News Release dated June 14, 2007). MC-05-18W3 and MC-05-18W4 intersected the mineralized Key Tuffite 40 metres west and 50 metres up dip of MC-05-18W2 respectively. New drill hole MC-07-25 intersected 0.96 metres grading 35.6% zinc, 1.82% copper, 54.9 g/t silver and 2.98 g/t gold, 100 metres up dip from MC-07-22 that intersected 5.04 metres of 19.30% zinc, 1.32% copper, 28.5 g/t silver and 0.75 g/t gold (see News Release dated June 14, 2007).
Other Activities
The Geological Survey of Canada (GSC) as part of the Abitibi TGI III initiative (http://ess.nrcan.gc.ca/tgi/index_e.php) released in early June an extensive gravity survey covering large portions of the Matagami Camp, the West Camp and the area between the two. A number of encouraging gravity targets have been identified and, combined with whole-rock geochemistry, suggest that the productive Key Tuffite stratigraphic package may be close to surface in areas not previously explored. A Titan 24 ground geophysical survey is underway over selected gravity targets.
About the Matagami Project
The Matagami Project has an area of mutual interest of 4,737 square kilometres and presently includes 2794 mineral claims covering 717 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 Mattagami 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 $23 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. Donner has discovered new mineralization on the Bracemac Property in the Upper Bracemac and Bracemac Zones and at the Key Tuffite horizon in both the Bracemac and McLeod areas.
Supplementary Information
