Colluli – World’s shallowest known potassium bearing evaporate deposit

By ABN Newswire,

EAST AFRICA focused potash company South Boulder Mines (ASX:STB) has announced Pre-feasibility Study results that show its flagship Colluli potash project could become one of the lowest-cost, and most significant, potassium sulphate operations in the world.

Operations will focus on the production of high quality potassium sulphate which commands a price premium over the more common potassium chloride product.

It is also the world’s shallowest known potassium bearing evaporate deposit.

Cash costs are forecast at US$189 per tonne of potassium sulphate, with the premium Anfile Bay potassium sulphate expected to fetch US$588 per tonne on market.  Continue reading PFS Proves Colluli a Low-Cost World-class Potassium Sulphate Project

South Boulder Publishes Prefeasibility Study (PFS) for Eritrea Potash Project

South Boulder Mines has delivered the Pre-Feasibility Study (PFS) on its 50% owned Colluli Project, located in the Danakil region of Eritrea. The PFS demonstrates that Colluli is expected to become one of the world’s most significant and lowest cost potassium sulphate operations.

By Esmarie Swanepoel,

THE prefeasibility study (PFS) into the Colluli potash project, in Eritrea, has estimated that the project would require an initial investment of some $442-million.

The PFS examined a two-module development with an expected production of 425 000 t/y sulphate potash for the first five years of operation, increasing to 850 000 t/y for the remainder of the proposed 30-year mine life.  Continue reading South Boulder Publishes Prefeasibility Study (PFS) for Eritrea Potash Project

Eritrea’s Unique and Unrivaled Potash Opportunity

Colluli is a considerably large and world’s shallowest deposit with a unique mineral composition and a coastal access that is unmatched

By Potash Investing News,

SOUTH Boulder Mines Ltd. (ASX:STB) is currently developing the emerging, world-class Colluli Potash Project located just 75 km from the Red Sea coast in Eritrea, Africa.

A large deposit and the world’s shallowest known potash resource, Colluli boasts a uniquely rare composition of three key potassium bearing salts in solid form. Combined, these favorable attributes make Colluli highly amenable to low energy, high potassium yield production of potassium sulphate (SOP).  Continue reading Eritrea’s Unique and Unrivaled Potash Opportunity

INTERVIEW: Colluli is the Most Exciting Potassium Sulphate Project Globally

Mr. Zeray Leake, Country Manager/ Chief Geologist of South Boulders Mines, Asmara

By Kesete Ghebrehiwet,

THERE have, of course, been a number of sites that harbor Eritrea’s natural treasures. Such wealth has by far been discovered in the post independence period. Bisha mining has become a key which opened the gate to the country’s natural resources. Zara mining which is nearing to start production has also become the next gold mine. Asmara Mining Project which covers mine sites in Dubarwa, Adi-Nfas, and Embaderho has ensured the sustainability of Eritrea’s booming mining industry.

Above all, Colluli, a world class deposit of potash, has been under development. Thus, every national has been eager to see what such resources of exceptional quality would bring to the national economy. As described at the 5th Asmara Mining conference, the mine life of Colluli potash contains over one billion tones of potassium. In a joint venture owned by South Boulder Mines and ENAMCO, each of the two parties has a 50% ownership of Colluli Mining Share Company.  Continue reading INTERVIEW: Colluli is the Most Exciting Potassium Sulphate Project Globally
