Aurumin Limited announced the first stage of exploration at its 100% owned Central Sandstone Gold Project is planned to commence next week, with a vehicle-mounted auger drill programme. All required approvals are in place, an auger rig has been secured, and mobilisation is planned for the week commencing 28th March 2022. The programme is designed to build on, and infill, 5 targets, generated through auger work completed by previous owners Middle Island Resources in 2021, whilst also testing 36 additional areas of interest identified by Aurumin geologists.

849 auger holes have been planned to test the bedrock interface for geochemical sampling. In addition to sampling for gold, the programme will commence building a comprehensive multi-element geochemical data set across the tenement package to assist in refining geological mapping, potential identification of geochemical signatures and improved vectoring towards mineralisation. AUGER PROGRAMME: Aurumin is expecting to commence exploration work at the recently acquired Sandstone Gold Project next week with an auger programme complimenting and extending work commenced by MDI in 2021.

This work identified 5 new targets: 2 Mile West, 3 Mile, Mt Klempt, Nugget Patch 1 & 2, and the Wirraminna North prospects. In addition to these targets, lineament mapping conducted by Aurumin geologists utilising high resolution Radiometric and Magnetic data, coupled with drone imagery, has identified another 49 areas of interest, of which 36 will be tested during the current programme. A suite of drilling has been completed over the tenements historically, however, gaps exist and remain prospective for gold mineralisation.

Multi-element data is limited over the tenement package, and this represents a historical deficiency in the data that has limited the ability to map underlying geology and deposit multi-element signals in the past. Aurumin believes an opportunity exists to identify additional gold-bearing mineralisation and fingerprint known targets for geochemical vectors. Gold will be analysed by fire assay, and a portable XRF will be used to assess first- pass screening of multi-element signatures.

Selected samples will be submitted for whole-rock geochemical analysis for lithological discrimination. The aims of the programme are to: Infill known areas of gold anomalism previously identified in the MDI 2021 auger programme, further defining mineralisation orientation and generating drill targets; Test new target areas for gold anomalism and lithological/geochemical signatures; Identify geochemical signatures of the mineralisation to provide vectoring and better targeting; Provide geochemical background/baseline data to validate and supplement existing data to assist in refining geological mapping. The programme comprises 849 holes with grid spacings ranging from 50m x 50m to 120m x 240m.

Grid sizes are a function of target maturity and the data required to increase the confidence in each target. Aurumin expects to generate drill targets and to highlight areas for further infill auger work from the programme.
