It also intends to list on Spain's Madrid, Barcelona, Bilbao and Valencia stock exchanges for the same reasons.

Berkeley is developing the Salamanca uranium mine in western Spain where it began construction at the start of the year.

"Given the geographic location of the Salamanca project in Europe and the size and maturity of the company and its operations, the directors consider that a listing on both the Main Board LSE and the Spanish Stock Exchanges is appropriate to provide the company with options for its future growth potential," Berkeley said.

The company said the new listings would give it access to new pools of capital it could not get exposure to previously, including large Spanish institutional shareholders, mutual funds, pension funds and retail shareholders in Europe.

It added that the potential for local Spanish ownership of Berkeley's shares was also an important strategic consideration.

Berkeley managing director Paul Atherley said the move would allow the company to build support amongst European institutional investors while advancing activities at Salamanca.

It said its shares expected to be admitted on the new exchanges on or around June 6-7, subject to FCA approvals, with trading to be cancelled on AIM simultaneously.

The company added that its listing on the Australian Securities Exchange would remain unchanged and shares would be transferrable between the ASX, LSE and Spanish stock exchanges.

Berkeley has a market capitalisation of A$215.08 million (US$161.8 million) in Australia, with shares trading at A84c Wednesday.
