Century To Develop Newly Discovered High-Grade Ore Zone At Sigma Mine Open Pit

BLAINE, WASHINGTON--(CCNMatthews - July 11, 2005) - Century Mining Corporation (TSX VENTURE:CMM) announces today the Company's geologists have located an unexploited high-grade ore zone immediately adjacent to the current open pit operations in the Sigma-Lamaque Complex located in Val d'Or, Quebec.

The zone, referred to as the Bedard Dyke, is contained within a highly-mineralized subvertical shear coincident with a porphyritic diorite dyke of the type historically known to host high-grade mineralization in the Sigma-Lamaque Complex.

A combination of reconnaissance, mapping in the open pit, and two historic diamond drill holes led to the discovery. Drill hole 18755 returned assays averaging 80 feet (24 metres) of 12.8 grams per ton (g/t) gold and hole 18803 intersected 210 feet (64 metres) of 14.9 g/t gold. The down-hole assay data show a typical log-normal distribution, with an estimated Sichel-t assay grade of 20.1 g/t. This delineates approximately 6,000 ounces within a cubic volume measuring just 25 feet (7 metres) by 50 feet (15 metres) by 100 feet (30 metres) on strike. The dyke remains completely untested down-dip and along strike to the west. The dyke has the potential to host several hundred thousand tonnes of gold-bearing material.

The Bedard Dyke can be accessed from the wall of the open pit, and because of the near-vertical nature of the structure, it can be easily mined by large-tonnage underground techniques. Historically, shears of this type in the Sigma and Lamaque Mines were extensively exploited in the underground workings. Further exploration and development work will be undertaken immediately on this discovery with the objective of developing the ounces to supplement the existing open pit operation.

This discovery is part of a major reconnaissance program which has just commenced at Sigma-Lamaque that combines data from grade control in the open pit, careful review of the historical data, and on-going reinterpretation of the local ore geology, to locate and exploit previously unrecognized resources within the Abitibi Greenstone Belt of Quebec.

Margaret Kent, President and C.E.O. commented: "This significant discovery confirms the potential of the Sigma-Lamaque Complex that we envisioned when we acquired the assets last September. We believe that there is potential to delineate over one million ounces of gold in known extensions to existing structures. We plan to carry out an exploration and development program on the unexploited high-grade ore zone with the objective of providing the material as mill feed within the next six months."
