MONTREAL, QUEBEC -- (Marketwire) -- 03/02/13 -- Mr. Harvey Keats, Chief Executive Officer of Donner Metals Ltd. ("Donner" or the "Company") (TSX VENTURE: DON)(FRANKFURT: D4M), reports that important high-grade sulphide mineralization has been discovered in drill hole MCL-13-25 between the Mineral Reserves in the McLeod Zone and the Inferred Mineral Resources in the McLeod Deep Zone. The hole intersected massive and semi-massive sulphides that returned 12.80 metres (7.33 metres estimated true width) grading 9.42% zinc, 2.51% copper, 35.71g/t silver and 0.81g/t gold from 932.40 to 945.20 metres. This result dramatically increases the likelihood that the two zones, separated by a 200-metre un-drilled gap, are connected by continuous high-grade sulphide mineralization. Five surface drills and one underground drill are currently active on the project, including three surface rigs at McLeod Deep.
Important high-grade sulphide mineralization has been discovered between the Proven and Probable Mineral Reserves in the McLeod Zone (2.1 million tonnes grading, 9.25% zinc, 1.18% copper, 24.98 g/t silver, 0.49 g/t gold) and Inferred Mineral Resources in the McLeod Deep Zone (2.47 million tonnes grading 9.20% zinc, 1.22% copper, 40 g/t silver and 1.1 g/t gold). This new result dramatically increases the likelihood that the two zones, separated by a 200-metre un-drilled gap, are connected by continuous high-grade sulphide mineralization, which has important implications for additional resources and extended mine life (Figure 1).
The current program on McLeod Deep is an aggressive 35,000-metre drill program designed to: 1) confirm the presence of mineralization between the bottom of the McLeod Zone, currently included in the mine plan, and the top of the McLeod Deep Zone (Figure 1); 2) provide the 50-metre drill hole spacing needed for the estimation and classification of the McLeod Deep Zone and its extensions as an Indicated Mineral Resource; and 3) to assess the continuity and distribution of gold grades previously encountered within the base metal sulphide mineralization in McLeod Deep. Importantly, the program will also investigate possible extensions of mineralization to the southeast, northwest and down-dip.
Two diamond drill holes were completed and three are in progress on McLeod Deep. The first three drill holes will also act as "pilot" holes from which multiple wedge cuts will be taken on an approximate 50-metre spacing. The program consists of 54 planned holes focussed on both the exploration and delineation of the McLeod Deep zone and its immediate area, including the area connecting the McLeod zone.
Diamond drill hole MCL-13-25 intersected massive and semi-massive sulphides over 12.80 metres (7.33 metres estimated true width) from 932.40 to 945.20 metres that returned 9.42% zinc, 2.51% copper, 35.71g/t silver and 0.81g/t gold. This intersection is located approximately 110 metres directly up-dip from the McLeod Deep Zone and 90 metres down-dip from the McLeod Zone. The intersection was followed by two well-mineralized zones of Pipe alteration and tuffite from 995.50 to 1,001.70 metres (6.20 drilled width - 3.59 metres estimated true width) and from 1,014.90 to 1,017.20 metres (2.30 drilled width - 1.34 metres estimated true width). These zones are characterized by Pipe alteration containing intermittent stringer, semi-massive and massive sulphide mineralization with variable amounts of sphalerite and chalcopyrite. The two intervals are separated by an unmineralized felsic dyke. Assays are pending for these two mineralized intervals.
