Donner Metals Ltd.: High Grade Discovered Between Bracemac and McLeod
|
VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 10, 2008) - Mr. Harvey Keats, Chief Executive Officer of Donner Metals Ltd. (TSX VENTURE:DON)(FRANKFURT:D4M), reports that exploratory drill hole MC-08-36 has discovered previously unknown massive sulphides at a depth of 110 metres that grade 18.10% zinc, 3.14% copper, 61.28 g/t silver and 1.37 g/t gold over 4.18 metres. This interval is 190 metres stratigraphically above the Key Tuffite horizon and located between the Bracemac and McLeod areas. High grade sulphides, grading 15.64% zinc, 0.51% copper, 31.19 g/t silver and 0.65 g/t gold over 2.75 metres, were also encountered in drill hole BRC-08-67 that extended the Bracemac Key Tuffite Zone. Exploratory drill hole MC-08-34, a deep test 470 metres down-dip from the New McLeod Zone, intersected 2.12 metres grading 10.81% zinc, 1.35% copper, 37.72 g/t silver and 0.59 g/t gold also at the Key Tuffite horizon. Two drill holes (MC-05-20W2, drilled west of the New McLeod Zone and MC-08-35, drilled up-dip of the Old McLeod Zone) both intersected high grade copper stringers in the alteration zone near the Key Tuffite horizon.

(i)Mineralization associated with "Pipe" alteration. "Pipe" alteration is
defined as intense chlorite alteration typically underlying or surrounding
zones of sulphide development and indicative of a hydrothermal vent system
associated with mineralization in the Matagami Camp. Magnetite,
chalcopyrite, pyrite, sphalerite, silica and talc may occur with chlorite.Bracemac Area
Bracemac Key Tuffite Zone
Three holes were completed up-dip of the Bracemac Key Tuffite Zone. Drill hole BRC-08-67 extended the zone with massive and semi-massive sulphides intersected 47 metres up-dip of BRC-07-64 (11.62% zinc, 0.39% copper, 17.74 g/t silver and 0.14 g/t gold over 10.2 metres). Drill holes BRC-07-68 and 69 were drilled 50 metres up-dip from BRC-08-65 (29.84% zinc, 0.04% copper, 6.62 g/t silver, 0.03 g/t gold over 2.50 metres) and BRC-08-67. Both of these holes intersected a gabbro-granodiorite dyke. The thickness of the dyke is unknown and further exploration up-dip is required to determine if mineralization extends to the other side of the dyke. The zone remains open down-plunge and to the west.
McLeod Area
Exploratory Drilling
Previously unknown high grade sulphides were encountered by diamond drill hole MC-08-36 at a stratigraphic level roughly equivalent to the Bracemac Zone that is located 900 metres west of this new intersection. Mineralization occurs at 110 metres below surface. It is cut by gabbro dykes and is underlain by a very strong "Pipe" alteration system that can be traced 190 metres downward to the Key Tuffite horizon. The alteration zone contains 5 to 50% disseminated, stringer and semi-massive pyrite with traces of sphalerite and chalcopyrite from 168.18 to 182.93 - assays are pending. This new system indicates strong potential for additional sulphide mineralization at both the new upper horizon and at the Key Tuffite stratigraphic level in this area.
The potential down-plunge of the New McLeod Zone was investigated by two deep, step-out drill holes. MC-08-34 intersected massive sulphides 470 metres down-plunge of the New McLeod Zone. The sulphides occurred within a well mineralized Key Tuffite which in turn was underlain by 10 metres of "Pipe" alteration. MC-05-20W2 was drilled 200 metres northwest of and down-plunge of MC-05-18W3 (6.48% zinc, 0.39% copper, 21.77 g/t silver, 0.44 g/t gold over 9.4 metres) and encountered 16 metres of "Pipe" alteration with local copper stringer mineralization. Both holes demonstrate that strong potential exists down-plunge of the New McLeod Zone.
Diamond drill hole MC-08-35 was drilled 250 metres up-dip of the Old McLeod Zone and intersected high grade copper stringers in the immediate hanging wall to the Key Tuffite. This mineralization occurs at approximately the same level as, and 120 metres east of, drill hole M-6 (1960) that returned 1.77% zinc and 4.21% copper over 6.95 metres. Underlying the Key Tuffite in MC-08-35 is 174 metres of "Pipe" alteration and strong chlorite alteration.
New McLeod Zone
Two wedged drill holes were completed in the New McLeod Zone. Diamond drill hole MC-07-31W3 was drilled 50 metres east and slightly down-dip of MC-05-18W5 (5.36% zinc, 4.55% copper, 65.22 g/t silver, 0.07 g/t gold over 1.40 metres). MC-07-33W1 was drilled 35 metres west of MC-05-18W3 (6.48% zinc, 0.39% copper, 21.8 g/t silver, 0.44 g/t gold over 9.40 metres) and 70 metres down-dip from MC-07-33 (13.30% zinc, 0.64% copper, 18.05 g/t silver, 0.71 g/t gold over 2.00 metres). The extent of the zone remains to be tested, particularly up-dip and down-dip of known intersections.
Four drills are active on the Matagami Project with continued step-out drilling at Bracemac and McLeod. A total of 51,788 metres of diamond drilling has been completed 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 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 $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.
