Century Mining Outlines Five New Mineralized Veins in the San Juan Mine-Sampling Returns an Average Grade of 20 g/t Gold

BLAINE, WASHINGTON--(CCNMatthews - Aug. 21, 2006) - Century Mining Corporation (TSX VENTURE:CMM) announces today that a total of 465 chip samples to test ore blocks within the San Juan Mine in Peru returned an arithmetic average grade of approximately 20 g/t Au. This sampling was completed to assess the available ore blocks in the San Juan Mine for mine planning purposes. A table of the ore blocks sampled is presented below:

The grades vary from a tenth of a gram to 302 grams per tonne gold while the average grade of the samples taken on each block varies from 3.3 to 69.0 g/t Au. The variability of the grades within the San Juan, Mercedes and Diagonal veins is typical of gold veins.

The San Juan Mine has historically produced 1.2 million ounces of gold from the San Juan and Mercedes veins, which have been mined over a strike length of one and a half kilometers and a vertical extent of 800 meters. The workings are accessed through interconnected adits in the hill above the river bottom where the mill is located. The veins remain open to depth and on strike and outcrop on the high plateau above the mine in an area called the Pampas zone.

Surface exploration in the Pampas zone has located several new veins adjacent to the northeast side of the San Juan Mine and parallel to the San Juan and Mercedes veins. These veins can be tested by surface drilling and have the potential to be mined over a strike and dip extent similar to that of the San Juan and Mercedes veins.

Recent surface sampling has confirmed that these veins are mineralized as shown in the table below. However, the average grade of the veins tested should not be inferred from these samples due to the small number of samples and the typical large grade variation found in gold bearing veins, as demonstrated by the assays from the San Juan and Mercedes veins.



---------------------------------
Vein and Chip Grade
Vein Sample Width g/t Au
---------------------------------
Veta A 1.70 m 1.80
---------------------------------
1.50 m 2.78
---------------------------------
Veta B 7.80 m 2.08
---------------------------------
Veta C 1.30 m 1.85
---------------------------------
Veta D 1.00 m 5.53
---------------------------------
Veta E 1.70 m 4.56
---------------------------------


The new veins in the Pampas zone represent a previously untested area measuring 200m x 250m and 600m x 150m.

The above channel samples averaged 2 kilograms in weight and were assayed by ALS Chemex in Arequipa, Peru. The samples were taken under the supervision of the Chief Geologist of the San Juan Mine, Hector Lazo Fernandez and Exploration Manager Erika Shepard. The samples were maintained in a secured area until delivered to the laboratory by company truck.

Diamond drilling is planned to test this area in addition to extensions of the San Juan and Mercedes veins as soon as drilling permits have been received. Drilling permits are being applied for and an archeologist is currently on site to fulfill the permit requirements for an archeological survey. The archeological survey will include all of the potential drill targets on the San Juan property. Recent bulldozer work has established drill roads to the area and water is available from the mine for the diamond drills.

The results herein described have been prepared under the guidance of Mr. Ross F. Burns, P.Geo., LG, Vice President of Exploration, who is designated as a Qualified Person with the ability and authority to verify the authenticity and validity of the data.

Margaret Kent, President and CEO, said, "We have now commenced exploration programs in Peru on the Golden Champune, Veta Clara and Santa Clarita properties as well as the San Juan Mine. We will have a very exciting fall as we start to produce results from this exploration work."
