Did you know you can visit our Porcupine Flat Processing Plant and see our gold processing operation in action?

Our public viewing platform provides an opportunity to see how ore is crushed, ground and processed to recover gold. Visitors can watch the different stages of the gold recovery process and gain a better understanding of the technology and infrastructure involved in modern gold processing.

The platform is located to the left of the processing plant entrance and is freely accessible to the public.

OUR OPERATIONS
OUR ENVIRONMENT

Following a recent geotechnical assessment, we are progressing plans for a new Tailings Storage Facility (TSF) at the Porcupine Flat Processing Plant.

The new facility, known as TSF4, will provide additional storage capacity to support processing operations. TSF4 forms part of an approved Work Plan and Planning Permit, with detailed engineering design work currently underway.

As part of the project:

🔹 New fencing will be installed around the site in the coming months

🔹 The existing Processing Plant Viewing Platform will remain unchanged

🔹 An additional groundwater monitoring bore has been installed, with further monitoring to be implemented if required

🔹 Site preparation works are expected to commence later this year

Tailings are the material remaining after gold is recovered during processing. These materials are placed in purpose-built storage facilities that are subject to ongoing oversight and regulation, including groundwater monitoring, geotechnical stability assessments, dust management, and cyanide management.

We remain committed to ensuring our tailings storage facilities are managed in a safe and responsible manner, protecting both the environment and the surrounding community while supporting the long-term operation of the Maldon Gold Project.

OUR COMMUNITY

Did you know that surplus water pumped from the Union Hill mine is distributed to around thirty local landholders?

The Nuggetty Water Group pipeline was established in 2007 by one of our predecessor companies, Alliance Resources, as part of an ongoing community initiative to help support local farmers and landholders.

In 2024, we undertook a comprehensive review of the program, including updating the pipeline mapping, environmental improvement plan, and community agreements, while also developing an audit system to support ongoing monitoring and review.

While water pumped from Union Hill is already suitable for stock watering, we’re currently installing a Lamella Clarifier, which will further improve water quality. The unit was previously used at our A1 mine near Gaffney’s Creek, where it significantly improved the quality of mine discharge water.

The Nuggetty Water Group is one of several ongoing community initiatives that we support. Others include maintaining water levels at the South German Dam, which provides an important water source for firefighting, and providing firewood donations to local residents.

These photo collages from our archives show the pipeline being installed in 2007, along with the historic moment water first began flowing through the system 🥳💧

Our latest quarterly Environmental Review Committee (ERC) meeting was held recently at the Porcupine Flat Processing Plant, providing community representatives and stakeholders with an update on activities across the Maldon Gold Project.

Updates presented during the meeting included an overview of operations, environmental monitoring activities, community engagement, and future planning across the project area.

Water monitoring programs continued throughout the reporting period, with results reviewed as part of ongoing environmental management activities.

Dust monitoring and suppression measures also remained ongoing, with no dust complaints recorded during the reporting period.

A number of community noise concerns were raised during the quarter and were investigated. Monitoring confirmed operational activities remained within approved conditions. These concerns were discussed during the meeting, together with measures being undertaken to monitor and manage operational impacts.

Community engagement activities continued, with a focus on maintaining communication with residents and stakeholders. This included media updates, direct engagement with neighbouring residents, and participation in the In Maldon Today radio program.

Ongoing initiatives to support the local community included continued supply of surplus mine water for local use, firewood deliveries, and the establishment of a text message notification system to provide notice of blasting activities.

We thank ERC members for their continued involvement and feedback, and we remain committed to ongoing communication and transparency as activities continue across the Maldon Gold Project.

OUR OPERATIONS

A surface drilling program planned for the Nuggetty area later this year is expected to build upon historical drilling and mining records, targeting both known mineralised zones and areas that have seen little or no modern exploration.

The proposed drilling campaign will focus on testing the main lode and southern strike extensions of the Nuggetty line of reef, including a recently identified section of previously untested ground.

Planned drilling targets include:

🎯 Main Nuggetty deposit – targeting mineralisation up to 120 metres below the historic Nuggetty adit

🎯 Nuggetty South – testing a previously unexplored 170 metre section of ground along the southern extension of the reef

Nuggetty Reef was first discovered during the 1850s gold rush and is recognised as one of the highest-grade historic gold deposits in Australia. The reef has an estimated historical gold production of 301,000 ounces from around 50,000 tonnes of ore, equating to an incredible average grade of approximately 187 grams per tonne.

Permitting for the program is currently underway, with drilling anticipated to commence in September and continue for several months.

The Union Hill team recently celebrated an exciting milestone, with a jumbo drill rig returning to service in the Union Hill decline for the first time in many years.

This moment marks the return of modern mechanised underground operations at one of Victoria’s most significant historic goldfields.

The jumbo will support ongoing underground rehabilitation, mine development, and the installation of modern ground support as work continues at Union Hill.

👏 Great work team!

Introducing the Mine Rehabilitation Team

Underground rehabilitation and site preparation form an important part of our ongoing work at Union Hill. Before further underground activities can begin, access, ground and site conditions must be carefully managed.

This work is carried out by the mine rehabilitation team:

🔹 Mingma Sherpa - Project Manager (centre)
🔹 Jackson McMahon - Jumbo Operator (right)
🔹 Kristen Grubb - Loader Operator (left)

Together, the team undertakes rehabilitation activities across the site, including drilling and blasting, installing ground support, moving waste rock, and maintaining infrastructure.

This work helps ensure conditions are suitable for personnel to operate safely and efficiently, supports access for modern mining equipment, and enables the development of exploration drives and underground diamond drilling.

The mine rehabilitation team plays an integral role in our work at Maldon, forming part of a structured and staged approach to site development at Union Hill. Rehabilitation works continue alongside ongoing exploration and reclamation activities across the broader Maldon Gold Project.

A text message notification system has been set up to provide updates ahead of blasting activities. If you would like to receive notifications, please get in touch at:

We recently hosted an underground training exercise run by the Central Victorian Mine Rescue Group (CVMRG) at our Union Hill Mine, with our own Sean McCubbin taking part.

The exercise involved ISH24, CFA’s Oscar 1, and emergency response teams from mines across Victoria, working together in a realistic underground scenario.

Sean also hosted a tour of our Porcupine Flat processing plant for attendees, providing an overview of site operations.

We were pleased to support the exercise through the use of our site and commend all those involved in the CVMRG for their ongoing work and commitment to mine safety across the industry.

OUR HISTORY
OUR COMMUNITY

Work on our Maldon Historical Data Compilation Project is continuing, with almost 1,000 historical items now digitised and consolidated into a structured archive.

The project focuses on researching and digitising historical records from across the Maldon Goldfield. This includes drill logs, maps, plans and reports from our own records, along with material sourced from government, museum, library and private collections.

Large-format maps and plans are being scanned at the Maldon Museum & Archives Association, creating a valuable exchange of information. Digitised items contribute to the museum’s collection, while its records continue to support our research.

This work is helping preserve the district’s mining history while building a clearer understanding of how the goldfield was explored and mined over time.

📌 Do you have historical material to contribute?

We are interested in hearing from anyone who may hold historical mining records, maps, photographs or documents relating to the Maldon Goldfield.

If you have any material that could assist in supporting this ongoing research, please get in touch:

Underground rehabilitation at Union Hill will begin in May, following recent infrastructure upgrades to support this next phase of activity.

The works involve rehabilitation of underground areas to the west of the pit, with controlled blasting required as part of the process. Blasting will be short in duration, occur as needed, and be carried out in line with relevant regulations and safety requirements.

We recently held a small meeting with residents living within 200 metres of the planned work area, providing an opportunity to share information, outline what to expect, and answer questions.

A range of measures are in place to minimise impacts, including:

• Careful scheduling of blasts
• Maintenance of equipment
• Use of a noise bund
• Dust suppression
• Blast design to minimise ground vibration

A text message notification system has been set up to provide updates ahead of blasting activities. Community members who would like to receive notifications can contact:
