- Goldphyre set to take the next pivotal step in its strategy to become a significant WA potash producer with the installation of four test-production bores at its Lake Wells Potash Project
- These simple, low-cost bores will measure the rates at which the brine containing the potash can be produced from the aquifers; Results will underpin further economic assessments of the Project
- The bores will be installed in the core high grade zone of the Resourcei (10.5Mt of SOP at a grade of 9.03 kg/m3) less than 5km from the proposed trial evaporation pond site
- The tests are aimed at confirming Lake Wells' position as a leading WA potash project, building on its superior Resource and close proximity to existing infrastructure
- Lake Wells has the distinct advantage of not requiring the more expensive trenching brine production method or the need to build from scratch costly logistics infrastructure
- Lake Wells has a superior Resource - using specific yield1 (drainable porosity), the Inferred Mineral Resource Estimate is:
18.4 million tonnes of SOP at 8.05 kg/m3 including
High-grade zone: 10.5 Mt of SOP at 9.03 kg/m3
- Geo-technical studies have started on the clays surrounding the lake surface to assess proposed site for trial evaporation ponds
- Laboratory evaporation trials testing salt crystallisation phases underway with second stage plan (1,000L bulk sample) being developed using local and North American-based process consultants
"Lake Wells is a leading WA potash project because it has a core of high-grade palaeochannel brine mineralisation, amenable to low-cost, proven brine extraction using conventional bores, and is close to infrastructure. We enjoy a strong supportive shareholder base, and a clear strategy to bring the Project to fruition as quickly as possible." - Goldphyre Executive Chairman Matt Shackleton
The first phase of the testing will involve the installation of four (4) test-production bores at two sites, A and B as shown in Figure 2 (see link below).
The installation of the simple, low-cost test production bores will be followed by test pumping, with the aim of confirming Lake Wells' status as a leading WA potash project, building on its superior high-grade Resource and close proximity to infrastructure.
The four test-production bores will be installed at two sites, with a shallow bore into the upper aquifer and a deeper bore into the basal aquifer at each site. The Company is reviewing consultant proposals to conduct the test-pumping program, scheduled to commence upon the completion of the bore installation program, with results expected in the December quarter.
At the same time, geotechnical test-work on potential trial evaporation pond sites, and laboratory evaporation and crystallisation trials, have commenced.
