Measured Mineral Resources are located in Galalar west, Main and East.
Indicated Mineral Resources are located in Galalar West, Main, east, North and Extended.
Inferred Mineral Resources are located in Galalar North and Extended.
A small proportion of Mineral Resource is located outside the Mining Lease Application area within EPM 27265. Mineral Resource extends below the water table in areas of Galalar east but the depths and extents are untested.
In 2019 a Scoping Study was completed, outlining the potential economics of the Galalar project resulting in the application of a Mining Lease.
As a component of the 2021 PFS, an initial mineral reserve for the Galalar project was estimated at 32.5Mt.
A maiden Inferred Mineral Resource was established in January 2022 within the Cape Flattery target area of Si2 North.
The initial resource comprises 53.2 million tonnes @ 99.32% SiO2. This high-purity silica sand, subject to further mineralogical testing, should be suitable for high-end glass manufacturing.
The project potentially seeks to exploit processed high quality “low iron” silica sand for photovoltaic applications (solar panels), and “ultra-low iron” silica sand for potential photothermal grade applications (ultra-thin electronics, computer and mobile phone screens).
The basis for this Maiden Mineral Resource Estimate comprises a vacuum drilling campaign carried out by Diatreme in November 2021, including accompanying field work. This Maiden Mineral Resource Estimate has been undertaken in accordance with JORC 2012 by carrying out comprehensive geostatistical evaluation by independent resource consultant Ausrocks Pty Ltd.
Diatreme identified Exploration Targets within the wider EPM 17795 totalling 210 million to 2.1 billion tonnes of silica (ASX announcements DRX 25/3/19, 11/4/19, 20/6/19). Within the northern section of the EPM 17795, Diatreme has high-graded four primary targets with an exploration target ranging from 40-160 million tonnes of silica.
