Blackheath Resources Inc. said May 26 that it decided to terminate its option over the Covas tungsten property in northern Portugal.
The company came to the decision following a review of all results of work undertaken to date and of future exploration requirements for the property.
Blackheath held an option to earn up to an 85% interest in the project from Avrupa Minerals Ltd.
The company will continue to maintain its interests in the Borralha and Bejanca tungsten projects, also in Portugal.
