• All five drillholes in the 2011 program intersected mineralization.
• Better grade mineralizations were intercepted at depth in the 2011 drilling program.
• The greatest exploration potential is in the Lower Zone, which has been traced for approximately 300 m of strike length and remains open both along strike and dip of the vein. At depth the zones widen and grades appear to increase.
• Three holes (AMT-11-01 to AMT-11-03) were planned at 50 m centres to test the 45-degree easterly plunge at staggered vertical depths.
• Two holes (AMT-11-04 & AMT-11-05) were planned to test near-surface mineralization intersected by the previous drilling.

VANCOUVER, British Columbia, Canada--(BUSINESS WIRE)--Jun. 2, 2011-- Abitibi Mining Corp (TSX-V:ABB) (“Abitibi”)/Sedex Mining (TSX-V:SDN) (“Sedex”) are pleased to announce a diamond-drilling progress report on their Tannahill gold property, which is favourably situated 16 km south of the past-producing Holloway and Holt-McDermott gold mines and can be reached by road from Kirkland Lake, 35 km to the southwest. Please see the location map. Abitibi and Sedex are 50/50 partners and joint venture operators.

Previous drilling has identified two parallel gold-bearing structures – the Upper and Lower Zones – oriented northeast and dipping to the north. Please refer to the attached cross section. The Lower Zone holds the greatest exploration potential and has been traced for approximately 300 m of strike length and remains open both along strike and dip of the vein. At depth the zones widen and grades appear to increase. Two holes below the 75 m level along 100 m of strike length have excellent widths with high gold grades (5.16 g/t over 5.0 m in drillhole T-96-9 and 7.02 g/t over 3.7 m in drillhole T-96-15). The drilling appears to substantiate the hypothesis of gold emplacement along radiating fractures. The Upper and Lower mineralized zones exhibit similarities with the style of mineralization in the Holloway and Holt-McDermott mines.

The 2011 program was designed to test a possible easterly plunge to the Tannahill mineralization suggested from the forty historic diamond-drill holes drilled in 1996 and 1997. Three holes were allocated to test the 45-degree easterly plunge at staggered vertical depths on section 3+50 East (AMT-11-01), 4+00 East (AMT-11-03), and 4+50 East (AMT-11-02). The remaining two holes (AMT-11-04 on section 1+50 East and AMT-11-05 on 2+00 East) were planned to further resolve near-surface mineralization where an upper and a lower zone were articulated by the historic drilling. Some 1380 meters were drilled in the five holes and 711 samples were submitted for gold assay to Expert Laboratories of Rouyn-Noranda, Quebec.

All five drillholes in the 2011 program intersected strongly-fractured to micro-fractured zones with alteration flooding and sulphide mineralization. The zones also had a common fault association. Drillholes AMT-11-01 (on 3+50 East) and AMT-11-03 (on 4+00 East) intersected the mineralized zones at depths of 270 m and 315 m, respectively, and encountered the best mineralization in the program. AMT-11-01 assayed 1.36 g/t gold over 4.15 m from 308.85-313.00 m, including 2.37 g/t gold over 2.0 m from 310.0-312.0 m. The mineralized zone in AMT-11-03 assayed 0.95 g/t gold over 11.1 m from 357.90-369.00 m including 1.11 g/t over 1.0 m (359.0-360.0 m), and 2.31 g/t over 2.9 m (364.10-367.00 m).

Drillhole AMT-11-02 tested the easterly plunge of the mineralization at a similar elevation as AMT-11-01 but was 100 m further east on section 4+50 East. It appears to be above the down-plunge extension of the main mineralized corridor, and assay results were low. Holes AMT-11-04 (section 1+50 East) and AMT-11-05 (section 2+00 East) intersected altered, fractured, and mineralized corridors. Assays reached up to 4.0 g/t gold over 1.09 m in the upper zone in AMT-11-05, but, in both drillholes, adjacent assays tended to be much lower and fragmented across the zone, such that a competent aggregate was not sustained. Please refer to the significant assay table below.

Historic mineralization is characterized by a strong-fracturing to micro-fracturing of both the mafic volcanic sequence and the felsic intrusive rocks. The fracturing is accompanied by an alteration flooding with ankerite and silica, along with varying proportions of sericite, fuchsite/paragonite, hematite, and, up to 7-10% pyrite. Most intersections also have a fault component. Historic intersections of 7.02 g/t gold over 3.7 m in T96-15, and 5.16 g/t gold over 5.0 m in T96-9 highlight the upper level of historic assay results. The historic results are pre-National Instrument 43-101 and must be verified by a QP before they can be relied upon.

The 2011 drill program appears to confirm a moderate easterly plunge in the order of 45 degrees for the main altered and mineralized corridor. Within this corridor, however, some of the historic, better-grade elements tentatively suggest a steeper plunge approaching 60 degrees east for the flanking mineralization. Moving forward, the mineralized zones need to be re-evaluated and new longitudinal sections constructed before proceeding with a deeper drill program.
