Below are some of the main news-driven share price changes today.
RISERS
LGO Energy (LON:LGO), up 36.8%. No news from the company but it did put itself up for sale a month ago so maybe some action is imminent.
Aminex (LON:AEX), up 15.0%. Another oiler on the rise; the company now now has a signed gas sales agreement for the Kiliwani North gas field, which means it can begin production and generate its first revenues from Tanzania.
Rockhopper Exploration (LON:RKH), up 14.8%. It is a hat-trick for energy companies, with the Falklands-focused explorer revealing plans have been upgraded for the first phase of the Sea Lion oil field development, in the North Falkland basin.
LOSERS
Kimberly Enterprises (LON:KBE), down 23.5%. The good news is the AIM-quoted Eastern European residential property developer has completed the disposal of two Canadian residential developments for a total cash consideration of C$ 20.2mln. The less good news is the company will cover less than half the outstanding debt to Engel Resources and Development.
Coal of Africa (LON:CZA), down 15.6%. The Integrated Water Use Licence for its Vele Colliery in the Limpopo Province has been renewed for a further twenty years. The company is, however, still waiting on a decision relating to a non-perennial stream diversion.
Webis (LON:WEB), down 11.7%. The company's WatchandWager.com subsidiary has signed a further three-year contract with the Hong Kong Jockey Club. The shares shot up to 2.74p this morning but crashed to 1.625p in the afternoon, down 0.22p on the day.
