Stone Ridge Quarry Project
Geological Resource
The Project is located on a northeast-southwest trending zone within the Eagleton Volcanics - one of the few geological formations in the Lower Hunter that is considered prospective for hosting quarry resources suited to the production of high-quality / high-specification quarry products. Boral's existing Seaham Quarry is located on the same zone, immediately southwest of the Project.
ARDG's comprehensive quarry resource assessment program was undertaken to a best-practice standard that exceeds the typical level of investigation undertaken by proponents of quarry developments in Australia. The detailed work program included extensive surface geological mapping and sampling, high-resolution ground magnetic surveying, approximately 1800 metres of diamond core drilling, downhole geophysics and exhaustive geotechnical testing on multiple bulk samples of diamond core.
Investigations confirmed the existence of a very large hard rock quarry resource, that upon receipt of planning approval translates to the following 'Reserves' and 'Resources' estimates in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the ‘JORC Code’):
The resource was confirmed by multi-parameter geotechnical testing to be suited to the production of a broad range of high-quality quarry products that include the following:

- Proved Reserves - 50.56 Mt
- Measured Resources - 80 Mt
The resource was confirmed by multi-parameter geotechnical testing to be suited to the production of a broad range of high-quality quarry products that include the following:
- Coarse concrete aggregates
- Fine concrete aggregates (manufactured sand)
- High-PAFV (Polished Aggregate Friction Value) asphalt aggregates
- Sealing aggregates
- Gabion
- Armourstone
- Roadbase and crushed rock products
