Project Development

Crossland’s project development strategy remains focused on updating the Resource Model and Charley Creek Scoping Study, as a necessary step for further funding of the project pre-feasibility study.

Results from our 2019 drilling programme will redefine the project. The infill drilling density is significantly greater than prior work and will allow us to identify higher-grade areas. Currently, SRK Consultants Perth is reviewing data from the drilling programme. Using this information, SRK will develop a resource model. Further metallurgical test work is required as support for the JORC 2012 Resource Estimation. These parameters will be used in the economic base case, as a requirement to establish reasonable prospects for eventual economic extraction (RPEEE).

Previously work focused solely on the recovery of monazite/xenotime minerals by gravity separation. Non-heavy minerals also contain a significant proportion of Rare Earth Elements (REE). Work is in progress to investigate the potential of REEs not recoverable by gravity separation and also the recovery of scandium. As of May 2020, the following tests are in progress:


  • heavy media tests and analyse concentrates,

  • bulk material feed preparation and tabling tests, to confirm indicative mineral process recovery for different material horizons,

  • preliminary 'sighter' tests to investigate the leaching potential of rare earth mineral mineralisation not heavy-mineral related,


  • assess the significance of scandium detected in the metallurgical test samples. Scandium was identified but not assayed in previous drill programmes.


Our metallurgical test work will challenge our existing process plant flow-sheet. This is an opportunity to further improve the current process flow-sheet, potentially reduce project capital, hopefully, simplify the process route and maximise the value of saleable products. At the same time, we seek to gain confidence in the preferred process flow-sheet for the larger scale "Proof of Concept" test work planned for later this year.

With the JORC resource report update can seek further funding to commence work necessary to complete the Scoping Study. Additional refinery product test-work is required to provide greater confidence in the refining process, product yields and specification. Large scale laboratory test-work, involving bulk material processing, is required to obtain sufficient concentrate for refinery test work. This work also serves to provide metallurgical and engineering “proof of concept” for several of the concentration processes; normally these tests are completed during the pre-feasibility stage.


By completing the described work programmes, Crossland can update the Stage 2 Scoping Study, the basis to raise funds at significantly higher market value. The total budgeted cost of the process/refinery test work programmes and the Stage 2 Scoping Study update are estimated to be $750,000 to $1M.


Following our air-core drilling programme completed in March 2019, our project team spent the next few months processing drill samples. By June 2019, our team completed :

  • logging of 139 holes (3,744 samples),

  • dispatch and receipt of assays for 105 holes (1,200 composite assays), and

  • preparation of 17 tonnes of metallurgical samples
