Snapshot	The ‘shovel-ready’ Cyclone Zircon Project is considered one of a handful of major zircon-rich discoveries of the past decade. The project has significant potential as one of the largest undeveloped, zircon-dominant heavy minerals projects in the world-class Eucla Basin. Primary approvals in place - project well placed for development, amid constrained supply and rising demand for critical minerals of high-grade zircon and titanium. Diatreme continues to advance discussions with a range of potential development partners for Cyclone, with the aim of maximising returns for shareholders. The Company is also undertaking further metallurgical testing to facilitate HM concentrate product samples and allow interested parties to conduct their own testing (on that sample) both in Asia and the U.S.

Deposit type

• Placer

Summary:

The deposit, an ancient coastal placer, is a surface deposit with low-grade overburden of about 9m to 18m, under which is a mineralised layer with an average thickness of about 13.5m, suitable for mining through an open-pit bulldozer mining method and conveyed by slurry pump. [FS p.28]

The Cyclone Deposit is made up of a number of mineralised strand systems which are interpreted to represent Tertiary beach placer deposits with associated overlying dunal and underlying near shore deposits. Quaternary cover overlies the deposit, and a shallow weathering profile with calcrete and ferruginous induration has developed in the overburden material, with the mineralised sands being free flowing with very little induration (rock) and low slimes contents which are favourable to conventional mining techniques.

Mineralisation occurs within bimodal near-shore fine sands, higher grade beach strandlines, homogenous beach sands, and overlying aeolian dune sands. A schematic stratigraphic column for Cyclone is presented below.

The mineralisation displays a very high value mineral assemblage and is dominated by zircon (31% of the HM) and a range of weathered / altered titanium bearing minerals (42% of the HM), with HiTi (70 85% TiO2) being the most abundant. Siliceous Ti-oxides (>10% SiO2) make up around 22% of the HM, but levels of other "trash" (i.e. low value) HM are very low.
