LEIGH CREEK, MOUNT HUTTON ACQUISITION

Crest announces it has entered into a Letter of Intent to acquire a 69.5% interest in WitchiMag Pty Ltd. which owns a 100% interest in the Mount Hutton magnesite property; and a 80% interest in MagMetal Tech Pty, which owns a 100% interest in the Leigh Creek magnesite property (together referred to as the "The Leigh Creek Project".) The Leigh Creek Project comprises exploration licences covering over 600 square kilometers in South Australia, hosting a number of magnesite showings.

Jason Cubitt commented: "Historic work on the Leigh Creek Project demonstrates a truly significant near-surface historical resource in a premier mining jurisdiction. This acquisition marks a major milestone for Crest and accelerates its progress into markets supportive of global decarbonization."

Magnesite (MgCO2) is a hard rock mineral which occurs in two main forms: crystalline and cryptocrystalline. Crystalline magnesite makes up around 93% of the world's magnesite resources and is found in carbonate rocks. Cryptocrystalline (also known as amorphous) magnesite makes up the remaining 7% of resources and is mainly hosted in ultramafic rocks and freshwater sediments.

About The Leigh Creek Project

The Leigh Creek Project is located in Southern Australia and is composed of two exploration licences totaling 664 square kilometres. Within the bounds of the project there are several historical magnesite occurrences the Mount Hutton South, Mount Hutton, Mt Playfair, Pug Hill, Termination and Witchelina.

Magnesite is predominantly present as magnesium carbonate and can either be upgraded via calcination into various industrial products or refined into magnesium metal. Crest is also reviewing the significant research that is being done on magnesium-ion battery formulations, as an alternative to lithium-ion chemistry, and will establish research partnerships to actively participate in this aspect of the global electrification initiative.

Magnesite showings on The Leigh Creek Project are of the cryptocrystalline sedimentary type, occurring in eoproterzoic skillogalee dolomite beds which are known to extend over 120 km in a north-west trend. The magnesite beds, which are up to 8 metres thick in places, were formed by almost pure magnesite precipitation in ancient, shallow marginal marine lagoons and mud flats. The cryptocrystalline magnesite clasts are set in a microcrystalline dolomite and talc matrix, and each magnesite bed has unique chemical and mineralogical characteristics making beds.

The magnesite occurrences on The Leigh Creek Project have historical resources associated with them. See table 1 below.

Table 1 - Leigh Creek Historical Resource

The Leigh Creek Project was formerly owned by a succession of related companies including SAMAG, Pima Mining and Magnesium Development Limited and Magnesium International Limited. For simplicity all reference to historic information will be attributed to SAMAG.

These mineral resources are historical in nature and should not be relied upon. It is unlikely they conform to current CIM Definition Standards. They have not been verified to determine their relevance or reliability. The workload required to update these mineral resources to the current CIM standards criteria has not been evaluated.

The historical resources above are all from a 2002 Feasibility study Generated by SAMAG Limited. The parameters use to calculate each of the above historical estimates are discussed below as known. The historical resources are reported using Australasian Code for Reporting of Mineral Resources and Ore Reserves how the categories were calculated are unknown.

The qualified person has not a not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves; and the issuer is not treating the historical estimate as current mineral resources.

Mount Hutton and Mount Hutton South resources are sedimentary magnesite beds were assumed to be tabular bodies, due to their planar top and bottom surfaces and consistent thickness. Tonnage calculations were made considering thickness, vertical depth, dip and specific gravity. All Inferred Resources were calculated to a vertical depth of 60 m. Thicknesses of each bed were calculated by considering the apparent thickness from drill intercepts and the bedding angle of the top and bottom contacts.

A thickness for each bed at an average dip was extrapolated halfway to the neighbouring traverse. Not all magnesite beds were targeted in each traverse as some beds were only intercepted twice. In this situation, beds were identified in outcrop along strike and placed in the Inferred Resource Category. Magnesite beds intercepted in neighbouring traverses are assumed to be continuous between traverses and hence were placed in the Indicated Resource Category. A total of 328 specific gravity readings were taken including 100 of dolomite interburden rock. An average specific gravity was used for lower beds, which were not sampled. Grades represent weighted averages of all intercepts used in tonnage calculations.

Witchelina Resource Measured Resources were calculated using wireframes and digital terrain model volumes. The consistent nature of the shallow marine sedimentary magnesite beds enabled this method to be used with a high level of confidence.

The simple geological structure and thick uniform width of the magnesite beds at Witchelina enabled confident interpretation of cross-sections. Magnesite bed drillhole intercepts were joined with the corresponding surface outcrop, and then interpolated or extrapolated to approximately 60 m vertical depth from the overlying ground surface.

Wireframe bodies were built by interpolating between magnesite intersections in each drill-section. Wireframes were then validated using Micromine, and visually inspected in 3D view. Resources were calculated from the wireframe using the Micromine Modelling Wireframe Reserves function. An average specific gravity of 2.91 g/mL was used for tonnage estimation. The average SG value was calculated from 53 magnesite half-core samples.

MgO and CaO grades from the downhole assay file were assigned to the wireframe using 3D-point method in the Micromine Modelling Wireframe Reserves function. The wireframes weighted average grades were calculated using the "from-to" weighted method available in the wireframe reserve calculation function.

A simple volumetric approach based on the assumption that magnesite beds represent tabular bodies was used to calculate tonnages from Witchelina drilling data. Weighted averages of all geochemical intercepts used in tonnage calculations constitute the grades quoted.

Myrtle Springs and Mount Playfair resources were calculated using a simple volumetric approach based on the assumption that magnesite beds represent tabular bodies was used to calculate the tonnages.

Pug Hill and Termination Hill Resource were calculated using a simple volumetric approach based on the assumption that magnesite beds represent tabular bodies was used to calculate tonnages from Pug Hill drilling data. Weighted averages of all geochemical intercepts used in tonnage clculations constitute the grades quoted.
