Aurumin Limited announced the first drilling programme at its 100% owned Central Sandstone Gold Project is expected to commence in May, with Reverse Circulation (RC) and Diamond (DD) drilling planned. All required approvals are in place and an RC drill rig has been secured. The RC drill rig is expected to mobilise the week commencing 9th May 2022, following completion of current works at its Mt Palmer Project.

The programme will focus both on testing depth extensions at the Two Mile Hill Deeps Deposit, and on testing the down plunge position of the high-grade core of the Shillington-Two Mile Hill Banded Iron Formation (BIF). Most of the drilling at Two Mile Hill to date has focussed on the top 250m of the deposit and has defined an open pit resource of 71,000oz. The deeper drilling that is present, although wider spaced, has identified high grade intercepts in the tonalite, often within larger moderate grade intersections (>2g/t Au), to a depth of 650m below surface; the deposit is considered open below this depth.

The existing inferred UG resource is 500,000 oz Au from 160m to 500m below surface. The drill programme at Two Mile Hill will target improving the data density in the area of sparser drilling between 250m and 500m below surface. This area is relatively under-drilled, however, the drilling that is present shows good vein frequency and high-grades typical of the tonalite style mineralisation at Two Mile Hill.

Five (5) holes for circa 3000m are planned. The programme will test hypotheses of controls on mineralisation. The overarching goal being to determine ore shoot controls and demonstrate that the broad >2g/t intersections can be linked into continuous zones.

This work aims to build towards defining a higher-grade resource that can be progressed towards production. The programme will use RC precollars with DD tails completing the holes through the area of interest. The focus of the diamond programme is on the tonalite body, however, mineralisation is also expected in the mafic and BIF units hosting the Two Mile Hill Tonalite.

The programme at the Shillington - Two Mile Hill BIF deposit targets the down plunge position of the Shillington Open Pit Resource (2,270kt at 1.2g/t for 86,500oz) and a hypothesised structural control to the BIF hosted mineralisation. The positions targeted correspond to the interpreted intersection of the structure into which the Two Mile Hill Tonalite has intruded. The linear structure hosting the tonalite broadly corresponds to a north plunging fold within the BIF unit and a series of narrower intrusive dykes.

Mineralisation currently modelled in the BIF units is discreet and laterally constrained suggesting intersections of, or interaction with structural features is key to localising mineralising fluids and allowing the deposition of high-grade gold within the BIF, making this area an attractive target. This programme will be completed with RC drilling. A main aim for this part of the programme is to intercept and/or identify geochemical vectors towards pods of BIF hosted mineralisation.

Thereby, seeking to link the core of the Shillington open pit resource with the well-defined high-grade pod of BIF mineralisation located on this structure at ~200m below surface and in the immediate hanging-wall to the Two Mile Tonalite. This BIF zone has been closely drilled from surface and is currently estimated to contain 200kt at 3.1g/t for 20koz. By targeting this position up plunge and along the intersection Aurumin seeks to add underground resources to complement the primary tonalite hosted system.
