STOCKS NEWS EUROPE-AIM index flat; Arian Silver jumps

Junior-listed AIM shares close flat, lagging the FTSE Small Cap index and the midcaps, which notch up respective gains of 0.5 percent and 0.6 percent, but outperforming the blue chips, down 0.3 percent.

Arian Silver Corporation (CDNX: AGQ.V - news) jumps 15.2 percent in volume around 1-1/2 times its 90-day average after it says that good progress is being made on the refurbishment of a processing plant in Mexico.

"Operating its own mill will allow the Company to significantly reduce the costs of production and improve silver recoveries, enhancing the project's economics," analysts at Northland Capital write in a note.

"The refurbished plant also allows Arian to increase production levels by three times that of each of the company's toll milling operations, once it reaches its maximum capacity of 1,500 (tonnes) per day."

Good Energy closes 0.6 percent higher after it announces that its Hampole wind farm in South Yorkshire has begun to generate electricity.

"This is encouraging news as the site has begun generating power quicker than we had expected (June 2014)," analysts at N+1 Singer write in a note.

"The company has now almost doubled the volume of renewable power generated by its own sites, and takes it a step closer to reaching the goal of generating 50 percent electrons by 2016."
