Big deal for minnow

POTASH miner Emmerson is close to inking a supply deal that could be worth as much as £4.4bn over the next 20 years.

It has signed an initial agreement to provide a global fertiliser trader with all of the product from its Morocco-based mine for the next five years.

But the Mail understands it is in discussions to provide all of its potash to the international firm, which it has not named, for the next two decades.

Emmerson listed on the London Stock Exchange last year and has a current market value of £24m.

It is understood that the international fertiliser trader is headquartered in Switzerland and has a large presence in Brazil.
