Aurumin Limited provided an exploration update for its 100% owned Sandstone Operations. Sandstone Operations has a combined Mineral Resource Estimate (MRE) of 946koz (19.3Mt at the 1.5g/t) Au. Initial soil sampling results for tenement E57/1140, acquired by Aurumin in June 2022, have been returned.

The tenement is hosted within the Sandstone Greenstone Belt, adjacent to the Youanmi shear zone. The tenement has seen relatively little exploration work and remains under-explored. The Ultrafine (UF) soil geochemistry results identified gold in soil anomalism and has been successful in generating several robust targets with a strike up to 1.4km long on the north-western margin of the Sandstone Greenstone belt.

Additional systematic UF soil sampling northeast of Two Mile Hill, has identified coincident gold and arsenic anomalies corresponding with a felsic intrusive intercepted in historical Rotary Air Blast (RAB) holes. The Two-Mile Hill Deposit is hosted by similar felsic intrusive. A broad-spaced systematic (100m by 200m) UF soil sampling programme comprising 497 samples was completed over the northern portion of the newly acquired tenement, E57/1140, located west of the Sandstone processing plant location.

Soil samples from the southern part of the tenement have been collected but have yet to be submitted for analysis, pending a review of results in the current round of analysis. There is no known drilling on the area of the tenement covered by this survey with the exception of a single line of aircore drilled on a small section of the northern tenement boundary, south of the Golden Raven prospect (Wamex A-107874). A desktop review of historical geochemical and geophysical data presented eight targets before undertaking the programme.

Gold and multi-element results from UF samples were normalised using median values as a proxy 'background' result, with results evaluated relative to these proxy background values. Four of the desktop targets have been confirmed with strongly anomalous gold values and a further two with elevated gold values. New targets have also been generated, including Starling, located at the intersection of two structural trends.
