Cluff Natural Resources has allowed another deal with Verus Petroleum, over assets in the North Sea, to expire amid "uncertainty concerns". 

The move follows a deal made last year with Verus to acquire a 25% interest in licences P1944 (Block 14/20e) and P2156 (blocks 15/11 & 16f), which contain the Fynn and Penny prospects.

The Fynn & Penny prospects are estimated to contain approximately 220 million barrels of potentially recoverable oil.
