The Red Hill Prospect is an exciting recent discovery for Heavy Minerals Limited with shallow high grade garnet being observed over a 1 km x 1 km area. The company believes this could be a significant resource in the near term.
The Red Hill Prospect is approximately 37 km South of the Port Gregory Garnet Project and approximately 70 km by road to the Port of Geraldton.
Given the proximity to Geraldton Port (approximately half the distance to Port compared to the RDG Lucky Bay Mine) any potential future operation here could have an advantage compared to similar operations in the region, due to lower transport costs.
The Geology at the prospect is analogous to the Port Gregory project with dunal sands overlying the Tamala Limestone formation. The frontal dunes and beaches in this area of the coastline have anomalous levels of very coarse garnet. This garnet has likely been washed down by the Bowes River from source rocks further inland. The target sand packages on the eastern side of the foredune area are also aeolian in nature and considered by the HVY team to be analogous to the sand packages hosting the identified mineralisation at the Port Gregory Project.
Wide spaced auger holes have identified significant garnet mineralisation over an area of at least 1 km x 1 km with notable intercepts including:
- 6.9% THM over 2 m from surface (HA037)
- 4.8% THM over 1.5 m from surface (HA040)
- 4.1% THM over 2.3 m from surface (HA029)
- 5.7% THM over 1 m from surface (DM001)
The high grade, shallow mineralisation intercepted in the recent auger campaign has elevated this prospect to a priority exploration target, with follow up drilling planned for 2022 to firm up the discovery.
