Sedex Mining Corp.: Tannahill Gold Project 2010-2011 Drilling Update

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 6, 2011) - Sedex Mining Corp. (TSX VENTURE:SDN) -

HIGHLIGHTS

  • The winter 2010-2011 drill program visually indicates all holes intersected varying degree of mineralization of up to 15m of cored lengths.
  • Previous drilling returned 5.16 g/t gold over 5.0m and 7.02 g/t gold over 3.7m in two separate drill holes.
  • Previous drilling has identified two parallel gold-bearing structures – the Upper and Lower Zones.
  • The Lower Zone traced for 300m of the strike length holds the greatest exploration potential and resembles Holloway and Gold Corp's Holt-McDermott style mineralization.

Abitibi Mining Corporation and joint venture partner Sedex Mining Corp are pleased to announce a diamond drilling progress report on their Tannahill gold property, which is favourably situated 16km south of the past producing Holloway and Holt-McDermott gold mines and can be reached by road from Kirkland Lake, 35km to the southwest. Abitibi and Sedex are 50/50 partners and joint venture operators. Please see the location map.

The Tannahill property is underlain by a sequence of metamorphosed volcanic rocks, which in the southern portion of the property have been disturbed by a large syenite intrusion. Emanating from the intrusion and cross-cutting the host volcanic rocks are a series of radial syenite dykes, which are thought to have been formed when the syenite was intruded into the volcanic rocks, fracturing them. The radial fractures would be ideal passageways for the transportation of gold-bearing hydrothermal fluids and the deposition of gold mineralization.

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 drill hole T-96-9 and 7.02 g/t over 3.7 m in drill hole 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 winter 2010-2011 drill program consisted of five drill holes totaling 1380m. The exploration rationale was to extend the plunge of the high grade intersections contained with the Lower Zone, both up and down plunge. Three drill-holes were drilled to test the easterly down-plunge direction and another two drill holes were designed to infill data in the up-plunge direction. Core logging indicates all holes intersected varying degrees of mineralization from 0.5m to 15m of cored lengths.

All drill holes have been logged and selected sections are being sent for assaying. Assay results will be released as they become available.
