The licence is host to the Bailieston gold exploration project and had been due to expire on March 27.
Asiamet Resources Ltd (LON:ARS) was also in the news as it said it continues to intersect high-grade polymetallic and copper mineralisation in drill core from the BKZ project in Kalimantan, Indonesia.
Highlights of recent results include up to 2.7% copper over a 1 metre intercept, as well as high-grade polymetallic mineralisation, with up to 25.5% zinc, 10% lead, 188 gram per tonne silver and 2.8 grams gold.
These results go to confirm further high-grade massive sulphide or vein style polymetallic mineralisation and copper-silver mineralisation, with both systems remaining open in several directions.
Meanwhile, Rainbow Rare Earths Limited (LON:RBW) sai dit expects to commission a new processing plant at the Gakara mine in Burundi later this month, after which the scale of mining should pick up sharply.
The plant is now running as designed, said Rainbow, and final adjustments have been completed.
Up until the end of December, 270 tonnes of material had been manually mined but with new plant Rainbow has a target of shipping 400 tonnes per month by the end of this year and 500 tonnes per month in 2019.

African Battery was formally known as Sula but changed its emphasis to cobalt from gold in January, with the target the emerging electric vehicle market.
Dr Boucher has extensive exploration experience in the region, and has now visited most of the known prospects and carried out geological mapping in key zones. A programme of geochemical sampling at the higher priority prospects is already underway, and this will help define drill targets.
The gold and copper exploration company, which has the Tulu Kapi project in Ethiopia, said its activities have been unaffected in terms of its daily interaction with the various government agencies and the community at Tulu Kapi.
