Century Mining Launches Major Exploration Project at Sigma and Lamaque Properties

BLAINE, WASHINGTON--(CCNMatthews - June 20, 2005) - Century Mining Corporation (TSX VENTURE:CMM) today announced the initiation of an exploration project at its Sigma and Lamaque properties to guide future mining expansion. The project will merge new information derived by the Company from its open pit mining with significant volumes of historic underground mapping, geochemistry and drill hole information to create a 3-D image of the mineralizing system.

"There are more than 6,000 drill holes on the Sigma and Lamaque properties dating from as early as the 1930s, when the mines first began operations. This does not include thousands of underground channel and face samples from the underground workings. Countless data sources exist, but to date, no one has compiled and interpreted the data," said Ross Burns, the Company's Vice President of Exploration. "Once completed, this project positions the Company for future mining expansion on the Sigma and Lamaque properties and will provide realistic guidance for exploration."

The data compilation project is expected to cost $500,000 and take a year to complete.

In conjunction with this exploration program a feasibility study will be undertaken focused on upgrading some or all of the existing 2.33 million ounces of gold in underground resources into a mineable category. The Sigma and Lamaque properties currently host just over four million ounces of gold in combined open pit and underground resources.

"This project is in line with our corporate strategy of developing properties with previously discovered, yet undeveloped, mineral assets. By creating a comprehensive picture of the properties using current and historic data, we can develop a list of potential targets for exploration and development that were left behind, not developed or not detected. This targeted approach will ensure a good success rate on our exploration resulting in enhancement of shareholder value," said Margaret Kent, President and Chief Executive Officer for Century Mining.
