While mining shares are seeing the biggest gains today, oil stocks are also helping to bolster the UK stock market as crude prices rise on news of possible output cuts.
BP shares are up 2.1% while rival oil giant Royal Dutch Shell is up 1.8%.
The FTSE 100 index is currently 21.38 points higher at 7,126.72.
It has been a bumpy trading day for the FTSE 100.
It has ended down 0.46% at 7,095.65.
BT Group is Thursday's best performer on the blue chip index, up 8.7% at 261.57p after publishing its interim results.
Share in BP, on the other hand, shed 4.85% to 539.8p despite revealing that third quarter profits reached a five-year high.
Conversely, the FTSE 250 finished 1.19% ahead at 19,142.82.
More on BP which has reported profits which more than doubled in the third quarter.
Its shares are up 3.8% at 555.70p.
The strength of the oil price over the quarter was of course a factor, particularly with BP’s break even level pinned somewhere around $50 per barrel. A sharp spike in earnings coupled with an increasingly streamlined operation led to a 124% rise in replacement cost profit year on year and a 73% rise quarter on quarter. This has provided an amount of cash which has several positive ramifications. In all, however, these numbers reflect a business which is back on its game and the initial share price reaction is understandably positive.
Profits more than doubled at oil giant BP in the third quarter, thanks to stronger oil prices.
"Underlying replacement cost profit" - the company's definition of net profit - climbed to $3.8bn from $1.86bn a year earlier.
"Operations are running well across BP and we're bringing new, higher-margin barrels into production faster through efficient project execution," boss Bob Dudley said.
The chief executive of BP has told CNBC that oil prices could face extreme volatility when US sanctions against Iran come into force on 4 November.
Bob Dudley said: "I think it's going to be 45 days of extreme volatility, it could spike up, it could also go the other way."
Much depends on whether companies are grated waivers by the US to continue doing business with Iran - earlier this week BP and Serica Energy were granted a new license to run a North Sea gas field partly owned by Iran.
Mr Dudley told CNBC: "If waivers were granted to others, to big oil consuming countries, you could see [the price] go down, there's a lot of uncertainty right now."
