The Great White Kaolin Project (GWKP) contains several high-value deposits containing a naturally occurring blend of halloysite tubes and kaolinite plates.

The GWKP is located within the District Council of Streaky Bay, near the community of Poochera on the Eyre Peninsula in South Australia.

We aim to develop the deposit into a world-class mining operation and produce the highest-quality halloysite-kaolin on the market.

By developing the GWKP, South Australia can become a key supplier of minerals that are essential for the world’s transition to a more sustainable future.

Project Approvals

An application for a Mining Lease (ML) for the mine, processing plant and supporting infrastructure was submitted in February 2021 to Department for Energy and Mining and approved in December 2021.

Applications for two Miscellaneous Purposes Licences (MPLs) for an access road to the ML, and a water supply pipeline from Poochera were also submitted and approved. The Mining Proposal, which accompanied the applications describes the Project, and investigates the possible impacts on the environment. Community consultation was a key part of this process.

Now that the Mining Lease is granted, Andromeda will submit a Program for Environment Protection and Rehabilitation (PEPR) for subsequent approval and will continue to engage with our community and stakeholders as part of this. Approval of the PEPR is required to allow the project to progress to the construction phase which is anticipated in 2022.

Frequently asked questions

General

The Great White Kaolin Project (GWKP) is a mining operation that will develop a world class kaolin deposit. Kaolin from the Great White Deposit is a fine white clay typically composed of 50% mineral kaolinite and 50% granitic sand, formed from the weathering of granite. The kaolinite is comprised of flat microscopic platelets approximately 0.003 mm thick along with a rare tubular (nanotube) form called halloysite. Kaolinite is chemically inert and non-abrasive.

The proposed mining process includes removing kaolin ore from the ground using conventional techniques of excavators and trucks. Stockpiled ore is then fed into a wet-processing plant. The plant will separate the two main components of kaolin: kaolinite and sand. Washed sand will be returned to the mined area or stockpiled for sale. The kaolinite concentrate will be dried and bagged for trucking to port.

Direct shipping of ore (DSO) to customers is also an approved operation for the GWKP.

The kaolinite product will be used in a range of applications and everyday products ranging from ceramics, paints, agricultural pest control, and paper, through to advanced technology for medicinal uses, air and water purification, soil remediation and battery technology.

South Australia has a two-stage approval system.

The first stage involved the application for Mining Tenements. Applications for a Mining Lease (ML) and two Miscellaneous Purpose Licences[HT1] (MPLs), supported by a Mining Proposal were submitted to the Department for Energy and Mining (DEM) in February 2021. The Mining Proposal defined the Proposed Development and provided government and the community information on how it will interact with the environment and included studies into the flora and fauna, hydrology, landscape, air quality, communities, businesses, traffic and infrastructure.

DEM granted ML 6532, MPL 163 and MPL 164 ("Mining Tenements") in December 2021, subject to conditions based on environmental outcomes ("Mining Lease Conditions").

A management plan called a Program for Environment Protection and Rehabilitation (PEPR) is currently being prepared as part of the second stage of the approvals process and will be submitted to DEM. The PEPR outlines control and management strategies to ensure that the GWKP complies with the Mining Lease Conditions. An environmental monitoring program is set out in the PEPR to measure any impacts for reporting against regulatory requirements.

Once the PEPR is approved, Andromeda may commence operations within the Mining Lease.

The GWKP will also be subject to a range of secondary approvals controlled by the Environment Protection Agency (EPA) and SafeWork SA.

Community engagement is a critical part of the PEPR process. Andromeda is currently undertaking work on its PEPR submission and will continue to meet with the community and stakeholders to ensure there is a clear understanding of the GWKP.

Community Drop-in Days information and feedback form

The GWKP will provide generational jobs and opportunities for the region for a planned Life-of-Mine of 28 years.

The proposed mining process includes removing kaolin ore from the ground using conventional techniques of excavators and trucks. Stockpiled ore is then fed into a wet-processing plant. The plant will separate the two main components of kaolin: kaolinite and sand. Washed sand will be returned to the mined area or stockpiled for sale. The kaolinite concentrate will be dried and bagged for trucking to port.

Direct shipping of ore (DSO) to customers is also an approved operation for the Development.

Mining will be undertaken during daytime only, 6 days per week. Wet-processing of the ore will be undertaken on a 24-hour cycle, 7 days per week.

Shift schedules for weekday, weekend and evening work are yet to be determined, however, all activities will be subject to the Environment Protection (Noise) Policy 2007.

Initially, diesel generators will power operations. After the construction of the wet-processing plant, [CM1] gas turbines will provide power generation and an opportunity to capture exhaust heat and gas for drying the product. This will provide a significant reduction in greenhouse gas (GHG) production and result in increased energy efficiencies. Gas turbines can be run on hydrogen, and it is anticipated that as hydrogen availability improves, the power generation requirements can be switched to green hydrogen.

Pending all required approvals and finance, on-site works are planned for the second half of 2022. Construction of initial infrastructure will take approximately 3 months from the approval of the PEPR. Mining will commence immediately after the completion of construction, with the associated processing infrastructure to be constructed thereafter.

Kaolin ore from the pit will be mined using conventional techniques using excavators and trucks, to a depth of approximately 40 metres, with shallow angled walls.

Kaolin ore will be fed into the wet-processing plant and washed with water from the granitic sand to produce a concentrated kaolinite product. The washed granitic sand is suitable for the building industry and will be sold where possible. If not sold, the sand will be dewatered before being returned to the pit by truck.

The kaolinite concentrate is refined using hydrocyclones, then dried and bagged. Bags [CM1] of kaolinite product will be transported to port using trucks.

Andromeda is committed to open, transparent, and engaging dialogue with communities, including Indigenous communities. Andromeda is actively engaging with The Wirangu People, who have connection to the country associated with the GWKP and are important stakeholders.

Water

Water is required for wet-processing the kaolin ore to separate the kaolinite from the granitic sand. Water will also be used for dust suppression around the mine, and on local roads. The Great White Kaolin Project has been designed to retain and recycle over 90% of its water.

During construction and initial operations, mains water will be trucked to site from Poochera, as required. After the construction of the wet-processing plant, a water pipeline from the trunk main at Poochera will supply up to 10 l/s, as required.

Both Andromeda and SA Water have a commitment to ensure water supply and pressure in the region to all existing users.

Andromeda will source water for the Great White Kaolin Project (GWKP) from the trunk main at Poochera by duplicating the existing infrastructure along Streaky Bay Road. The existing supply line will be supplemented with a parallel pipe (larger in diameter than the existing infrastructure) to the Poochera – Port Kenny Road offtake. Water supply for the GWKP will be taken at this point while still providing additional capacity for the existing Streaky Bay and Chandada/Inkster water users.

A new water pipeline has been designed to extend supply from Streaky Bay Road to site and will be installed in the Poochera – Port Kenny Road reserve and adjacent to the GWKP’s access road to the mine site. This is currently in engineering and design phase.

Andromeda will duplicate the existing infrastructure along Streaky Bay Road from the Eyre Highway to Poochera - Port Kenny Road. The new pipe will be larger in diameter than the current infrastructure and installed at Andromeda's cost.

A new water pipeline has been designed to extend supply from Streaky Bay Road to site and will be installed in the Poochera – Port Kenny Road reserve and adjacent to the Great White Kaolin Project’s access road to the mine site. This is currently in engineering and design phase.

The new connection from the trunk main at Poochera has been designed to supply water to the Project without any adverse impacts to existing water users.

Water available to the wider community will increase at the intersection of Streaky Bay Road and Poochera – Port Kenny Road, after supply to the Great White Kaolin Project (GWKP) has been taken into account.

Groundwater drawn from the region’s local bores by current users has been included in the Project’s hydrogeological studies. The nearest groundwater user is 4 km away from the GWKP with no impact expected from mining operations.

Andromeda must ensure that there is no adverse impact to the quantity and quality of groundwater available to existing users and groundwater dependent ecosystems as a result of mining operations. Andromeda will implement a groundwater monitoring program of bores located within and around the mine area, measuring quantity and quality of groundwater.

A hydrogeological study was conducted as part of the Mining Proposal to understand groundwater in the area around the Development and the potential effect on current users. The local groundwater is limited and not suitable for use for human consumption. The nearest groundwater user is 4 km from the proposed mine. Modelling predicted potential impacts of the proposed shallow mining and indicates that the Great White Kaolin Project will not affect the ability for existing users to access groundwater.

No. The fracture-bound granite aquifer beneath Great White Deposit is limited in quantity and too high in salinity to be used in the wet-processing operation. It may be able to be used in limited amounts for dust suppression.

Dust and air quality

Andromeda must ensure there are no public nuisance impacts and health impacts from air emissions and /or dust generated from mining operations. Additionally, Andromeda must ensure no impacts to agricultural productivity to third party users as a result of dust generated by mining operations. Andromeda will undertake ongoing air quality monitoring around the ML to ensure and demonstrate that the dust generated from site does not exceed the limits set by the EPA and specified in the Mining Lease Conditions.

Dust management will be undertaken in a number of ways:

  • Roads will be defined and constructed using aggregates and binding agents.
  • Speed limits will be applied on all mine roads.
  • Maintenance of internal and access roads with use of dust suppressants.
  • The mining schedule will allow areas where the kaolin is removed to be backfilled and revegetated to stabilise the area progressively over the Life of Mine.
  • The processing plant will use a wet process, which processes the slurry, dries and seals the product in bags for export.
  • Landscaped earth bunds and boundary vegetation will surround the operating area to provide ground protection and windbreaks.
  • Our workforce employed in the mine area will be trained and focused on safe work practices which minimise dust.
  • A water cart will be used to reduce the likelihood of dust in working areas.
  • Air quality in the region is generally very good, though the area does experience very dusty conditions on occasion. In recognition of the conditions in the region, the Development has been designed to minimise dust generation.

Dust generation from site is unlikely to impact agricultural productivity; in fact, kaolin dust is used in many agricultural businesses to improve soils, control pests, limit sun damage and loss of moisture through transpiration.

Andromeda is currently collecting data using dust monitors and gauges around the Project area to understand baseline dust levels. Andromeda must ensure no impacts to agricultural productivity to third party users as a result of dust generated by mining operations.

Roads and traffic

Andromeda has committed to upgrading Poochera – Port Kenny Road and its intersection with Streaky Bay Road in consultation with the District Council of Streaky Bay, and the Department of Infrastructure and Transport. The proposed upgrade of the Poochera – Port Kenny Road has been designed to improve the vertical and horizontal alignments and widen the road where necessary to ensure safety for all road users.

Upgraded designs for the intersection of Streaky Bay Road and Poochera – Port Kenny Road have been provided to the Department for Infrastructure and Transport for review and approval.

Andromeda has committed to halting haulage trucks along Poochera - Port Kenny Road during the time of school bus runs.

A traffic assessment for the Great White Kaolin Project has been undertaken by Tonkin Consulting. It determined that A-triple trucks are currently the most suitable for the Project. The A-triple combination is a common truck on the roads and is used to transport grain from regional silos to ports across the Eyre Peninsula. Further assessments on suitability of vehicles, sizes and combinations determined that combinations up to quad road trains could be used.

The use of A-Triple trucks will provide a frequency of approximately 10 truckloads of product per day for transport to port for Stage One increasing to approximately 20 for Stage Two.

Andromeda is working in consultation with the District Council of Streaky Bay and the Department for Infrastructure and Transport to determine the appropriate traffic route depending on the port chosen.

Three port options are currently being considered:

  • Thevenard
  • Lucky Bay, and
  • Whyalla.

For all port options, trucks will travel along Poochera – Port Kenny Road and Streaky Bay Road to the Eyre Highway.

Due to the increase in traffic, there will be an impact on local roads. Andromeda has committed to upgrading Poochera – Port Kenny Road and associated intersections to accommodate haulage trucks from the Development. This commitment extends to ongoing maintenance of the road for the life of the mine. The redesign of the road will benefit all road users.

Andromeda has engaged Tonkin Consulting to redesign Poochera – Port Kenny Road and the intersection with Streaky Bay Road to meet the Austroads standards. Upgrade designs have been provided to both the Department for Infrastructure and Transport and the District Council of Streaky Bay for review and approval. The intersection will be widened to cater to all trucking configurations considered for use at the Development.

Yes.

The intersection of Poochera - Port Kenny Road with Streaky Bay Road will be upgraded to support the Project. Upgrade designs have been provided to both the Department of Infrastructure and Transport and the District Council of Streaky Bay for review and approval. The intersection will be widened to cater to all trucking configurations considered for use at the Development.

An assessment of sight distances for vehicles entering Streaky Bay Road from Poochera - Port Kenny Road, was completed and found that the roads exceed the relevant Performance Based Standards (PBS). The existing lane and shoulder widths of Streaky Bay Road to Poochera are also acceptable, based on the PBS.

Safety for truck drivers and the public is a paramount concern for the Great White Kaolin Project. Poochera – Port Kenny Road will be upgraded and maintained to ensure safety for all road users. Andromeda will maintain the road to ensure it remains in safe and in a serviceable condition.

In response to community feedback, Andromeda is committed to halting haulage trucks along Poochera – Port Kenny Road during the time of school bus runs.

Throughout the school year, the school bus will occasionally run outside its normal schedule, such as on sports days and at the end of terms. Andromeda will work with the school community on changes to operational scheduling associated with irregular school bus trips.

Economic opportunity

Yes - up to 70 direct jobs will be created in the Poochera/Streaky Bay region with full-scale operation of the Great White Kaolin Project (GWKP). This will bring combined incomes of over $7 million per annum into the community through salaries alone. Increased economic activity in the area associated with the GWKP will support the development of additional services in the region, such as childcare and health care.

Andromeda has a "shop locally" policy and opportunities for supply, contracting and other services will be available. Once the Project gains the necessary approvals, supply requirements will be communicated through Streaky Bay’s Local Business Directory.

Environment

Andromeda must ensure that noise emanating from operations is in accordance with the current amenity as defined by the Environment Protection (Noise) Policy 2007 and the relevant land use zoning as defined by the Planning, Development and Infrastructure Act 2016 at the date the Mining Lease was granted.

The Environment Protection Authority (EPA) stipulates noise limits during construction and operation under the Environment Protection (Noise) Act 2017 (EPP).

A noise impact assessment undertaken for the GWKP by independent noise experts Resonate Consultants indicates that relevant noise criteria is unlikely to be exceeded during construction or operation. Bunding, site location, design and selection of plant and equipment, will be used to minimise noise impacts.

Andromeda must ensure that there are no adverse impacts to:

  • public safety;
  • human comfort;
  • third party property (including stock);
  • adjacent land use; and
  • aircraft

from airblast, flyrock and vibration caused by blasting.

The deposit is typically free dig, due to the low strength characteristics of the clay and overburden of soil, sand and silts. There are harder overlying rafts of silcrete and calcrete which will generally be ripped with a dozer prior to excavating. Some areas may require limited drilling and blasting, on an as needs basis. Small, controlled blasting will be undertaken to fracture the rock to allow it to be excavated. Andromeda will comply with the Australian blasting compliance limits set out in AS 2187.2-2006 to ensure that impacts are minimised. Any impact is significantly reduced by distance from the mine. The nearest sensitive receiver (residence) is over 1 km from the mine area.

Andromeda must ensure that there are no native fauna injuries or deaths due to mining operations that could have been reasonably prevented.

As with any new development there will be an impact on native flora and fauna. The key is to understand and minimise the impact and where possible, remediate to offset the impact. Desktop studies, followed by field surveys were undertaken by ecologists to understand the existing natural environment. As part of the environmental surveys, a wider area around the Great White Kaolin Project (GWKP) was included to understand if there could be any associated impacts.

The GWKP is located in an area described, on a native vegetation scale, as highly degraded by agricultural practices. Specific attention was given to identifying any listed species that could be impacted by the GWKP, specifically the Malleefowl. There are no expected impacts to the surrounding native flora or fauna or Matters of National Environmental Significance (MNES).

The Great White Kaolin Project (GWKP) is predominantly located within previously cleared agricultural land, but in order to access the kaolin deposit, some clearance of existing vegetation will be undertaken. The GWKP footprint has been designed, where possible, to avoid native vegetation. To offset the reduction in native vegetation, a contribution of Significant Environmental Benefit (SEB) is required. As part of the ongoing mine works, the mined areas will be progressively rehabilitated and revegetated.

Miscellaneous Purposes Licence (MPL) 164 was granted for the mine access road along the northern boundary of the adjacent Crown land which is covered by Native Vegetation Heritage Agreement (HA 511). This includes a small portion of this land, which has been degraded by historic quarrying. The route for the mine access road was selected to minimise impact on both native vegetation and arable agricultural land. The route is also the most direct path to the Eyre Highway and therefore minimises ongoing emissions from product transport.

Andromeda must ensure that the land is progressively and finally rehabilitated to support the future land use agreed with the regulator (DEM). Rehabilitation will involve the backfilling of the pit where possible and reforming the land profile to a stable form prior to the reinstatement of soils. Investigations of the soil profile indicate it is naturally high in boron and may not be suitable for cropping following mining.

Andromeda is committed to reinstating the land to a safe and stable condition which includes re-vegetation. As the mine progresses and overburden is backfilled in the mined area, the rehabilitated landform surface may be lowered due to the removal of kaolin ore with changes to the resulting landform slopes.

A mine closure plan will be approved by DEM as part of the PEPR before any construction works or mining start.
