Hardie Pacific is committed to reducing carbon emissions. With the global focus on greenhouse warming and the rapid increase in international carbon pricing, the race is on to find new forms of permanent carbon dioxide removal (CDR). Aotearoa NZ and NSW, Australia’s Mg0 endowed ultramafic rocks, notably Dunite and Serpentinite, chemically react with CO2, forming stable minerals. This process has become an acceptable, permanent form of carbon removal. Our aim is to become the Southern Hemisphere’s major Carbon Sequestration hub.
Weora Limited
Weora Limited, another Aotearoa NZ registered company, holds 7 Mineral Permit applications totalling 1,886 km2. Our first deep drilling well located at Green Hills, has reached its target depth of 800m. The second well is progressing well. Aotearoa NZ is recognised as one of the worlds largest ultramafic rock deposits.
Weora plan to either:
- inject CO2 deep underground (in-situ) or
- quarry, crush and mix with CO2 (ex-situ) to form stable carbonate material suitable for industrial material manufacturing such as CO2 neutral cement, plasterboards and other construction materials.
This process is today naturally occurring wherever these ultramafic rocks are surface exposed at Green Hills, and West Dome, Southland, Fiordland National Park Red Hills and the Dun Mountain complex near Nelson.
Our established team in Aotearoa NZ is engaging with large CO2 emitters, Iwi, Government at all levels. Sampling and laboratory test work with research organisations is underway.
Carbozorb Pty Ltd
Carbozorb Pty Ltd, an Australian NSW registered company, holds 6 Mineral Exploration Licence applications: EL9377 ‘Bingara’, EL9351 ‘Boggabilla’, EL9352 ‘Clarence’, EL9374 ‘Coolac’, EL9420 ‘Nyngan’, and EL9407 ‘Nyngan North’ totalling 2,282km2.
Carbozorb is evaluating the potential suitability of surface and buried ultramafic rocks within the NSW Great Serpentinite Belt (GSB) and Coolac Serpentine Belt for sequestration of CO2 either through using direct air capture or emissions direct from polluting industries. The advantage of these deposits are that they are located in the high sun belt zones, suited for solar powered direct air capture (DAC) and sequestration.
The target commodities are Olivine and serpentinite.
Australian researchers have been studying the prospects for mining these serpentinites for the past decade, crushing them prior to mixing with CO2 to manufacture various building and construction components.
