HANSON – ABORIGINAL CASE STUDIES RED HILL QUARRY WA Red Hill Quarry is located on the Darling Scarp, 20kms to the north-east of Perth on country of the WHADJUK Noongar people who have lived in the south-west of Western Australia for more than 45,000 years. Red Hill Quarry is a key strategic operation for Hanson in Western Australia and an important source of concrete aggregates, road building materials, rail ballast and rock products for the Perth metropolitan area and surrounding regional communities. Red Hill has a number of significant heritage sites including the Owl Stone, lizard traps, ochre deposits, other noted rock formations and scattered artifacts. Buffer zones and detailed management plans are in place to protect sites from quarry activities. We have ongoing engagement with Traditional Owners at Red Hill, both in facilitating visits to sites such as the Owl Stone (Pictured) and also working with Traditional Owners and archeologists in understanding the significance of artifacts associated with the site. Four grinding stones were identified during surveys over the site some years ago. In recent years, post achieving the relevant development and environmental approvals required for the quarry, we have continued to support sub-surface archaeological investigations and study of the area from which the grinding stones were collected. Working under the supervision of the local Aboriginal people, archaeologists have completed technical investigations using non-invasive short wave infrared Figure 1: Owl Stone - Red Hill Quarry. spectroscopy and hyperspectral core imaging Hanson Photo stock in order to determine the specific past uses of the stones. Going forward we continue to support access to significant sites and study of artifacts including the griding stones, along with exploring ways to further recognition of and promote the significance of Red Hill to the Noongar people.
