MOUNT CROSS KEY RESOURCE AREA – KRA 79
LOCAL GOVERNMENT AREA: Gatton Shire
LOCATION:
The resource is located adjacent to Seventeen Mile Road about 16 kilometres northeast of
Helidon (see map KRA 79).
EXTRACTIVE RESOURCE: Quarry Rock
EXTRACTIVE RESOURCE DESCRIPTION:
The extractive resource consists of a deposit of greenstone, which occurs adjacent to
Seventeen Mile Road northeast of Helidon. Only a limited proportion of the resource area has
been investigated in detail to date but large resources are likely to be present. Testing
indicates the rock to be suitable for good quality aggregates for the full range of applications
from road bases, road sealing aggregates and concrete aggregates. The greenstone deposit has
not been worked to date.
SIGNIFICANCE:
The resource is sufficiently large and of such quality that it represents a significant regional
resource for the long-term future.
SEPARATION AREA:
The separation area is largely defined on the basis of a full separation distance of 1000 metres
from the resource boundary. The separation distance has been reduced where intervening
ridges or high relief allow a lesser distance from the resource boundary than the 1000 metres.
TRANSPORT ROUTE:
Seventeen Mile Road is already used to transport building stone from several sandstone
quarries closer to Helidon onto the Warrego Highway at Helidon. The use of the part of the
road north of the sandstone quarries for the transport of extractive materials would be
consistent with this designation.
SPECIAL CONSIDERATIONS:
The KRA contains areas having State biodiversity significance under the Environmental
Protection Agency's Biodiversity Planning Assessment and encompasses three cultural
heritage sites of State significance. The Xanthorrhea Nature Refuge is adjacent to the western
end of the resource/processing area. The KRA is adjacent to the Lockyer Forest Reserve.
The KRA contains land classified as good quality agricultural land (mostly Class C1
improved pastures, with small areas of Class B and Class D non agricultural land).
