Colluli Pilot Tests Produces Ultra High Purity Potassium Sulphate

South Boulder Mines pilot tests conducted for the Colluli SOP project DFS have produced ultra-high purity potassium sulphate grades. i.e 98% K2SO4 achieved in final Colluli product vs typical industry product of 94% K2SO4

By Proactive Investors,

SOUTH Boulder Mines (ASX:STB) pilot tests conducted for the Colluli SOP project Definitive Feasibility Study (DFS) have produced ultra-high purity potassium sulphate (SOP) grades.

Potassium sulphate is a premium potash fertiliser used for chloride intolerant crops and arid climatic conditions.

The pilot tests have provided SOP samples that can be introduced to potential commercial partners.

Samples are still being generated as the pilot plant trials progress from 20 hours trial runs to 40 hour trial runs.

These results were consistently achieved from a series of pilot plant runs conducted throughout March 2015.  Continue reading Colluli Pilot Tests Produces Ultra High Purity Potassium Sulphate

Colluli Potash Mine Life Estimate Exceeds 200 Years

Colluli Potash Project in Eritrea: It is the world’s shallowest deposit – the only open pit deposit in the world – the world’s closest to the coast (65Km) potash deposit, and – the lowest mining cost in the industry (US$75 per tonne). Under the new estimation, its mine life has now increased from 50 to 200 years

Colluli Potash mine is the closest to coast potash deposits in the world and located near to the key growth markets for potassium fertiliser – primarily India and China

By Proactive Investors,

SOUTH Boulder Mines (ASX:STB) is making steady progress at its Colluli Potash Project in Eritrea, where it is conducting economic assessments and project planning that could confirm its potential to process all salts present.

This includes potassium sulphate, a premium potassium fertiliser which currently carries a price premium of approximately $300 per tonne, is ongoing.

This could deliver a significant boost to Colluli’s economics, including a considerably lower strip ratio and therefore reduced costs.  Continue reading Colluli Potash Mine Life Estimate Exceeds 200 Years

Colluli Potash Project in Eritrea will Define a New Path Forward
