Minefinders Corp has announced a mineralised zone discovery at its Dolores mine in northern Mexico.

Chief executive Mark Bailey said the initial drill results of the North Dome deposit are encouraging and demonstrate the presence of a well mineralised area extending over 600m of strike length.

A core drilling campaign will be started in the quarter to test the deeper potential of the North Dome target, the company said.

The Dolores mine is located in the Sierra Madre occidental range of northern Mexico and has a deposit and an open-pit mine life of 15.5 years.
