High Purity Quartz Quarry Project located south-east of Port Hedland, in the Pilbara region of Western Australia, and is host to an Inferred Mineral Resource Estimate of 6.2 Mt at 98% SiO2.
- Significant high grade quartz deposit with potential for premium High Purity Quartz (HPQ) production
- IND holds exclusive option to acquire 80% mineral rights at Pippingarra Quarry
- Granted Mining Lease (M45/258), active mining operation with fixed and mobile plant, site infrastructure and camp facilities
- Located <40km from Port Hedland with public road access to the port
- Direct Shipping Ore (DSO) ore sorting trial to recover pure quartz from existing waste stockpiles
Pippingarra Quarry Inferred Mineral Resource Estimate using 90% SiO2 cut-off within pegmatite lithology domain. Differences may occur in totals due to rounding.
| Resource Classification | Density (g/cm³) | Volume (000,000) (m³) | Tonnes (000,000) (t) | SiO2 (%) | Al2O3 (%) | CaO (%) | Fe2O3 (%) | MgO (%) | Na2O (%) | K2O (%) | TiO2 (%) |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Inferred | 2.60 | 2.4 | 6.2 | 97.99 | 0.92 | 0.00 | 0.06 | 0.01 | 0.10 | 0.20 | 0.02 |
| Total | 2.60 | 2.4 | 6.2 | 97.99 | 0.92 | 0.00 | 0.06 | 0.01 | 0.10 | 0.20 | 0.02 |
The Mineral Resources are reported on a 100% basis, while the option agreement between IND and the lease holder, once exercised, allows for an incorporated joint venture with IND as manager (80% IND / 20% NWQ).

Pippingarra Conceptual Exploration Target within pegmatite body (exclusive of Mineral Resource)
| Target | Lower Tonne Range | Upper Tonne Range | Upper Content Range | Lower Content Range |
|---|---|---|---|---|
| SiO2 | 35M | 50M | 85% | 98% |
| Muscovite Mica | 10M | 20M | 40% | 60% |
| Potassium Feldspar | 10M | 25M | 40% | 60% |
Cautionary Statement: This is an Exploration Target. The potential quantity and grade is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource over this wider area and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
