The Project sites are located approximately 2,200km (direct distance) north of the capital city of Perth, or 3,200km if travelling by road.

It is in the Kimberley Region of Western Australia. This region has a long history of exploration and is home to a number of mining operations, including that of the successful, but recently closed Argyle Diamond Mine, which is nearby.

Infrastructure in this region is well developed despite being so remote. It has all-weather roads, hydro-electric power, an abundance of water and good communication structures for mobile and internet connectivity. The tenements have access to the Great Northern Highway, rated to operate quad-trains (4 trailers on a prime-mover), and are located between 90km – 110km from the Port of Wyndham.


Exploration History

The region of the project area has an extensive exploration history mainly targeting diamonds and base metals. There has been no recorded exploration targeting high quality silica sands. Diamond exploration has been focussed on the search for kimberlite pipes and alluvial diamonds.

In 2021, Allup Silica conducted a sampling program within E80/ 5524.

These were grab samples taken from the surface with a shovel. Sample locations are shown alongside:

Details for the Argyle Silica Exploration Project


The surficial deposits covering the area of E80/5629 and E80/5524 are dominated by alluvium and colluvium associated with the confluence of the Dunham River and Cabbage Tree Creek. This consists of sands, gravels and clays overlying the Devonian, Cambrian and earlier Proterozoic rock units. The following graphic shows the two tenements with the surface geology mapping from the 1:250000 Lissadell mapsheet, SE52-2.

The colluvial and alluvial deposits are shown in yellow with the occasional outcrop of the underlying Devonian sandstone (labelled DC on map).


And this graphic shows the geology of E80/5652 from the Cambridge Gulf 1:250000 SD52-14 map-sheet, with the recent alluvial sediments associated with the Eight Mile Creek making up the majority of the tenement area.
