Updates from Game Digital, Polymetal and Segro

More momentum for the FTSE 100 on Tuesday with shares climbing 2.6%, a 157-point climb taking it to 6,240.9. Miners, again, gained with Anglo American surging more than 9% to 323.35p and Glencore up 8.4% to 93p, helped by a lift in oil prices and bullish OPEC comments. There were also steep gains for BHP Billiton, Rio Tinto and BG Group - all saw shares climb more than 6%. However, outside the FTSE 100, shares in Game Digital collapsed by almost 40% on fresh profits worry.

Stateside, optimism was carried into the third consecutive day with the Dow up more than 185 points to 17,602.6. However the Dow remains 1.2% down on the year as a whole.

We start Christmas Eve with news of a Polymetal joint venture with OJCS Polyus Gold in the development of the Nezhdaninskoye gold deposit in Yakutia, Russia. Polymetal says there is significant potential of a high-grade mine with a long mine-life.

The Russian London-listed gold producer says it will acquire up to 50% in the joint venture entity holding. The total amount of Polymetal's investment - at this stage - will be US$18m in cash.

"We believe," says Vitaly Nesis, Group CEO of Polymetal, "Nezhdaninskoye fits perfectly with Polymetal's core competencies in remote asset development, selective underground mining, and refractory ore processing."

Next, grim earnings news for Game Digital saw a precipitous fall, as just mentioned, in the company's share price yesterday. Game Digital said earnings are likely to come in at around the £30m mark rather than £43m a year ago.

"The switch over from the older gaming formats to PlayStation 4 and Xbox One software has impacted profitability across the UK market," said chief exec Martyn Gibbs.

However the fall-off in sales comes at the most crucial time of the year for Game and suggests future concern on the durability of console sales in particular.

Lastly, real estate investment trust Segro says it's to offload its portfolio of offices on the Bath Road in Slough for £325m to clients of AEW Europe.

The sale price represents a net initial yield of 5.6% says Segro and a small premium to book value at 30 June 2015. The transaction is expected to complete during January 2016.

The proceeds will be used to reduce the Company's gearing and to fund the trust's development pipeline.
