"We see the Two Mile Hill Deeps resource as a key part of the project going forward, with the scale to potentially underpin future production. This extra drilling could prove important in better understanding the deposit's potential."

DRILLING PROGRAMME

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(Figure 1).

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(Figure 2through Figure 5). 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.
