THE DRILL SERGEANT: Kalium Lakes (ASX: KLL) has completed Bankable Feasibility Study (BFS) sonic monitoring bore installation and air-core geological programs at the company’s Beyondie sulphate of potash project (BSOPP) in Western Australia.
Kalium Lakes conducted some 8,504 metres of drilling throughout the program, which it said had continued to confirm the PFS Resource and Reserve Assumptions, reaffirming the project’s high-grade potassium results while indicating new aquifer targets.
The drilling returned potassium results up to 11,100 milligrams per litre (mg/L) – equivalent to a sulphate of potash (SOP) grade of 24,736mg/L.
The company has test pumping activities ongoing, with results being utilised to update the BFS numerical hydrogeological modelling of the project’s Ten Mile and Sunshine Stage 1 production areas.
Kalium Lakes explained the program is aimed at achieving future Measured Resources and Proved Reserves to support project financing requirements.
“The program has continued to confirm the Pre-Feasibility Study Resource model within our initial Stage 1 Mining Lease Areas,” Kalium Lakes managing director Brett Hazelden said in the company’s announcement to the Australian Securities Exchange.
“We envisage these results will enable an upgrade of the deposit to include a future Measured Resource and Proved Reserve, which in turn will support the Bankable Feasibility Study and project financing.
“The current assumed Stage 1 Area has a mine life of 23 years at 75,000 tonnes per annum SOP, when utilising our existing Probable Reserve, which has enabled Kalium Lakes to have very detailed discussions with both domestic and international offtake parties and financial institutions.”
