News: South Boulder Mines (ASX:STB) Colluli Potash Project

.

East Africa focused emerging potash company South Boulder Mines (ASX:STB) (OTCMKTS:SBMSY) is on the development path at its Colluli Potash Project in southern Eritrea, East Africa, where the company's work on a pre-feasibility study is well advanced.

The Perth-based, ASX-listed company's project hosts a large, high grade potassium bearing resource close to surface, in close proximity to the Eritrean coast and geographically favourable relative to key markets.

Colluli lies in an emerging potash province, the Danakil Potash belt, which currently hosts over 4.2 billion tonnes of measured and indicated potassium salts. Danakil compares favourably in terms of size, resource depth and environmental issues against other potash belts globally.

The project itself hosts over 1 billion tonnes of potassium bearing salts including sylvite, carnallite and kainite salts which are all suitable for the production of potash fertilisers.

What makes this project unique is that it is one of only three major global deposits containing kainite salt in solid form. The fact that the salts are in solid form is a major differentiator from other projects which require potassium-rich brines to be evaporated in order to create salts.

Kainite is the most important salt used for low cost production of potassium sulphate (SOP), a premium potash product with a substantial price premium over potassium chloride (MOP).
