Bono says the band are recording some good material.
U2 have announced their first album in five years will not reach stores until 2009.
Frontman Bono said in a statement on the band's website the group are on a roll with their songwriting and are reluctant to stop now.
The follow-up to the 2004 album How to Dismantle An Atomic Bomb has been in the pipeline since last year and recording sessions have taken place in Morocco and Dublin, as well as the south of France.
However as they are so confident in the quality of what they are producing at present, Bono claims they plan to continue and not rush the release of the disc.
"We've hit a rich songwriting vein. It gets a bit dark down here but looks like we've found diamonds not coal … why come up above ground now if there's more priceless stuff to be found?," Bono said on the website.
The frontman said everybody involved with the record is pleased with the direction it is headed and the new work will be available next year.
In other news, Bono has been blamed for some of the band's new material being posted on the internet after he played tracks too loudly at his villa in the south of France.
