A bulk sample of harvest salt from the Stage 1 Kainite ponds was collected in March to confirm plant feed grades and produce mass samples of sulfate of potash (SOP) for end user customers.
Chemical analysis of these harvest salts has indicated potassium salts kainite and schoenite (as modelled) are present with a potassium concentration of 7.5%, above the modelled assumed plant feed of 6.8%. Sulfate concentration of 20.9% also matched expectations.
Results for other compounds, namely sodium and magnesium align with the anticipated plant feed grade.
The bulk sample confirms the Lake Way operation is precipitating plant feed harvest salts suitable for conversion to premium quality SOP in the designed flowsheet. This will be further confirmed via process testwork at Saskatchewan Research Council (SRC) in Saskatoon, Canada.
Tony Swiericzuk, CEO, said: “These positive results confirm our Stage 1 ponds are operating within design parameters and are producing high grade potassium feed salts which can be converted to premium quality SOP. Following the strong results from pumping our first brine abstraction bore reported last week, today’s results further highlights the extent to which the Lake Way project and our on-lake production process has been de-risked over the last twelve months.”
