Much of the eastern side of the very large, 5,745 square km saline playa Lake Torrens, which occupies one of the most arid parts of Australia, was taken under licence by a Northern Territory - based company with the intent of systematically sampling deep sulphate-rich brines from aquifers buried beneath the lake's salty surface crust, and assessing their potential to produce potash minerals which could be used to make fertiliser. Potash and/or schoenite fertiliser can be produced by simple staged solar evaporation and flotation and/or other onsite treatments. Australia has no producing potash mines. Around 350,000 tonnes of potash, worth around $200 million, are imported into Australia annually from Canada. Potash of sulphate and schoenite are utilised as high-end fertiliser products globally, as they have a lower salt index than muriate of potash and are often preferred in feeding crops sensitive to chloride or susceptible to fertiliser burn. Sulphate of potash and schoenite attract premium pricing in comparison to the more common muriate of potash. During the initial year of tenure, no field work was able to be done (reasons why are given below). Instead, literature reviews and a desk-top assessment of the prospectivity for potassium, lithium, bromine and boron alkali salts were undertaken. A single-pass helicopter reconnaissance flyover was conducted across Lake Torrens on route to another destination, without landing. The lake surface was observed to be gypsiferous clay with very little white halite at all. Numerous camel tracks cross the northern third of the lake. These tracks looked to be quite old. A straight-line set of wheel tracks was obvious crossing the entire central lake east-west from shore to shore. No birdlife was observed, and there was no other wildlife visible on the lake. A Lake Torrens work program proposal (PEPR application) was submitted to DSD on 19/5/2015. This was for brine sample collection from shallow hand-auger dug holes. On 4/6/2015, a Form 27 was sent to Native Title custody parties and relevant Government departments, and was followed-up by sending a copy of the PEPR to the Native Title custodians' legal representatives. On 9/7/2015, a request for further information was received from DSD, noting that a new template was needed, that approval would take 3-5 months minimum, and that no approval would be given until Native Title heritage protection considerations had been addressed in accordance with Part 9B of the Mining Act. In particular, this meant that that the Kokaltha Aboriginal Corporation would defer presenting its views in relation to Rum Jungle Resources’ proposal until the then current Lake Torrens litigation had been completed in the Federal Court. Alternative, helicopter-facilitated access was proposed for the hand-auger sampling program. The proposed hand-augering was determined not to be “drilling”. Subsequently, land access negotiations stalled pending receipt of further advice from the Kokaltha Aboriginal Corporation, so the viability of the Lake Torrens Project was reviewed by the licensee. It was recommended to fully surrender all four tenements and abandon the project because of: - no clear line of sight to being able to engage with and negotiate an agreement with Traditional Owners; - the impost of high holding costs without the ability to undertake on-ground work; - results of an assessment of the geology and hydrology, which downgraded the eastern portion of the lake relative to the western portion which Rum Jungle Resources did not hold; - anticipated logistical and technical difficulties in performing any future deep drilling on the soft and boggy lake surface; - potential future difficulties of undertaking any mineral extractive development within a National Park; and - the requirement to reduce the exploration portfolio to better utilise limited funds.
