Carnegie potash project prospectivity confirmed

Kalium Lakes Ltd (KLL) and BCI Minerals Ltd (BCI), the owners of the Carnegie potash project (CPP) via the Carnegie joint venture (CJV), have reported brine analysis results for the initial auger sampling programme completed at the project.
The CJV has also presented recent geophysics results associated with identifying the potential palaeochannel location, and provided an update on other works undertaken on the CCP so far.
The auger holes completed are located on granted tenement E38/2995, which is the eastern tenement of CPP. Assays from this initial programme returned potassium grades of up to 4790 mg/L (equivalent to a SOP grade of 10 674 mg/L). These results are positive and compare favourably with other SOP exploration and development projects in the region.
Brine samples were also collected in order for evaporation and processing bench scale testwork to begin. This work is scheduled to start this month and will take several months to finish.
The CJV has completed an initial geophysics desktop assessment to identify the potential palaeochannel locations and followed up with a field geophysics programme consisting of 123 km of traverses.
The field data has been analysed and interpreted. When combined with publicly available information from other projects to the south, the data has identified the likely continuation of a palaeochannel from Lake Wells extending north through CPP’s E38/2995 tenement. Drilling targets designed to test both the location and depth of the interpreted palaeochannel system have been identified and will be tested throughout the next few months.
Scoping study activities have been underway since 2017 and are progressing to plan. So far, hydrogeological desktop study works have been completed and environmental and regulatory approvals requirements have been identified. The CJV is targeting completion of the scoping study in April this year.
The works completed so far, as well as Carnegie’s extensive area, confirm the project’s potential scale and prospectivity, with positive initial brine assays results and a lake surface footprint that is much larger than other SOP exploration projects in the area.
Alwyn Vorster, the Managing Director of BCI, said: “These results are encouraging and confirm BCI’s original assessment of Carnegie’s potential compared with numerous other Australian SOP exploration projects. Carnegie offers multiple technical and commercial synergy points with BCI’s Mardie Salt Project and forms part of BCI’s diversification into agricultural and industrial commodities.”
Brett Hazelden, the Managing Director of Kalium Lakes, added: “The works undertaken to date have benefitted from our significant intellectual property developed, in conjunction with our key consultants, during the past three years. The prospectivity of the Carnegie system is now evident and these results confirm its status as a significant second project in our portfolio, although it has received little recognition from the market to date. This project also provides a growth opportunity to expand from our initial development of the Beyondie sulfate of potash project and will utilise all of the synergies and learnings that go with it.”
