Grants and Grants Basin Iron Ore Project
Grants and Grants Basin are very large iron ore deposits that are favourably located within 10 km of the Transcontinental railway line and approximately 75km west-southwest of Broken Hill.
Grants iron ore deposit contains a JORC Inferred Resource of 304 million tonnes of 24% Fe at a cut-off grade of 18% Fe. The deposit forms a homogeneous hull-shaped body of iron ore up to 180 metres thick from surface and covering approximately 130 hectares, with minimal internal waste and almost no overburden.
Grants Basin, lying immediately to the east, contains an Exploration Target* of 3.5-3.8 billion tonnes of 24-28% Fe . Drilling to date has discovered iron ore mineralisation in a large basinal shape over about 25% of the total area of the Grants Basin. The deepest drillhole so far is 624 metres, that includes a 488 metre continuous iron ore intersection grading 24.6% Fe.
(*noting that the Exploration Target is conceptual in nature and there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource)
Investment opportunity
Havilah is seeking an investment partner to assist in funding a pre-feasibility study (PFS) with the right to participate in financing development of the project for an equity interest. Investment terms are flexible. Discussion is welcomed with interested parties who have the financial capability.

Project status update
PFS work planned to commence with a resource drilling program at Grants Basin in late 2020.
Project dependencies
Expected start date - Planned PFS work over the next twelve months includes drilling at the western outcropping end of Grants Basin in order to delineate a JORC resource of 500-800 million tonnes of iron ore. Metallurgical test work will be carried out on available drill core.
Expected end date - Grants and Grants Basin combined are vast iron ore deposits and potentially, once in production, could sustain large scale operations for many decades.
Funding round finish date - Available for immediate investment to progress the PFS.
Technology utilised
Planning for a modern energy efficient conventional open pit mining operation and an iron ore upgrading and pelletising plant that utilises the latest technology including:
Low CO2 emissions with the majority of power from renewable sources due to the abundance of sunlight and wind in the area (energy storage via hydrogen production).
Surveying and pitwall stability monitoring to be controlled by a state of the art I-Site laser scanner.
Highly automated and innovative dry processing magnetic separation plant that minimises water usage and environmental impacts such as tailings storage.

Project highlights
- Simple orebody geometry and large resources – thick basin shape from surface to 180 metres depth (for Grants) and almost 500 metres deep (for Grants Basin) with minor overburden and consequently a very low waste:ore ratio. Indications are that Grants is a very large Pilbara-scale iron ore deposit that could support a large, long term mining operation over many decades.
- The ore is comparatively soft and the processing characteristics are likely to be similar to Maldorky i.e. iron minerals are readily liberated with a low energy grind and beneficiation (upgrading) to a high quality 65% product grade by conventional, mostly dry processing methods. Unwanted element levels such as Al and P are very low. The fines product is suited to pelletising using locally sourced bentonite.
- Favourable logistics, including a continuous, heavy duty rail link to the Spencer Gulf ports of Whyalla, Port Augusta and Port Pirie (and Port Waratah and Port Kembla in the east). The deposits lie from 8 to 10 km south of the Transcontinental Railway and the Barrier Highway and 75 km west - southwest of the major regional mining centre of Broken Hill, with its skilled workforce.
