OUR PEOPLE

There’s a lot that goes on behind the scenes here at Kaiser Reef, and none of it would be possible without the dedication and commitment of our fantastic support team.

Led by Administration Coordinator Kerri Mason, the team includes Office Assistant Alisa Lim and Head Cleaner and Driver Sabrina Smythe.

Affectionately nicknamed “The Sheriff”, Kerri brings a wealth of experience to her role and seamlessly manages everything from procurement and payroll to supplier communications, property inspections, and organisation of staff housing, cleaning and accommodation.

Before joining us at Kaiser Reef, Kerri worked at a 5-star hotel on the Gold Coast. She traded high heels and dresses for hi-vis and safety boots when she arrived here at the Porcupine Flat Processing Plant. During her first eighteen months with us, when the team was much smaller, she even assisted with pouring gold bars!

Alisa recently joined us as Office Assistant and is the friendly and capable face of the front office at the Porcupine Flat Processing Plant. In addition to assisting with payroll, she manages accounts payable, IT coordination and daily office duties.

Keen to expand her knowledge and understand all things mining, Alisa has embraced her role with determination and enthusiasm. She is a welcome addition to the team and plays an important part in keeping the office running smoothly each day.

Head Cleaner and Driver Sabrina is a dedicated Maldon local who manages cleaning and deliveries across our operations. Along with keeping the Porcupine Flat Processing Plant and Union Hill Mine clean, Sabrina transports mine and plant samples to the laboratory in Ballarat every day for assaying.

Sabrina’s cheerful nature and can-do attitude make her a valued member of our team, and she continually goes above and beyond in her role.

Together, Kerri, Alisa and Sabrina work tirelessly behind the scenes, helping keep our operations across the Maldon Gold Project running smoothly. Thank you for everything you do! 👏

OUR ENVIRONMENT
OUR COMMUNITY

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 minimal dust complaints recorded during the reporting period.

A number of community noise concerns were raised during the quarter and were investigated. While monitoring confirmed operational activities remained within approved conditions, additional measures were taken to help minimise noise impacts. These concerns were discussed in detail during the meeting.

Ground vibration monitoring confirmed all vibration related to blasting remained within regulatory limits.

Community engagement activities continued, with a focus on maintaining communication with residents and stakeholders. This included media updates, direct engagement with neighbouring residents, letterbox flyer distribution, and a text message notification system to provide notice of blasting activities.

Ongoing initiatives to support the local community included firewood deliveries and continued supply of surplus mine water for local use.

The Union Hill lookout was repaired and refurbished, and sponsorship was provided for the Maldon Winter Festival.

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

Exploration is advancing at Maldon following the completion of preparation works in the Union Hill decline. Underground drilling is now underway, targeting potential mineralisation in the vicinity of Union Hill and marking another important milestone for the Maldon Gold Project.

🔹 Drilling is being undertaken from a newly established underground drill location approximately 200 metres from the portal, at a vertical depth of about 85 metres.

🔹 The primary targets are the Linscott’s and Eaglehawk vein systems in the Union Hill area, with several holes also planned to test Ladies Reef, located approximately 150 metres west of the existing underground workings.

🔹 The initial drilling program is expected to continue for at least three months and could be extended depending on assay results.

🔹 Decline refurbishment and blasting remain ongoing at Union Hill.

Drilling from underground allows drill holes to begin closer to the target vein systems and can reduce drilling distances compared with testing the same targets from the surface.

Results will be reviewed by the Exploration Team and incorporated into a three-dimensional geological model. This model will help geologists assess the extent and orientation of potential mineralisation and assist in planning further exploration targets.

Each completed hole will add another piece to the geological picture as exploration continues across the Maldon Gold Project.

OUR HISTORY
OUR OPERATIONS

Have you ever wondered what lies beneath your feet here at Maldon? As well as our Union Hill decline, Maldon is home to hundreds of historic mines, with a vast network of underground workings developed over more than 170 years of mining.

Our exploration team combines historical mine plans and geological records with modern exploration data to reconstruct some of these mines in three dimensions. These models allow our geologists to visualise the relationship between the historical workings, geological structures and mineralisation, providing greater insight into the ground below the surface and helping guide future exploration.

We are fortunate to be working in a goldfield with such a rich and interesting history. More than 170 years after gold was first discovered here, we’re proud to be continuing Maldon’s mining story today.

OUR OPERATIONS

We would like to thank the local community for their patience and understanding during the recent airborne magnetic and radiometric survey. Thanks to favourable weather conditions and the efficient progress of the survey team, the program was completed earlier than anticipated.

During the survey, a helicopter measured subtle variations in the Earth’s magnetic field and naturally occurring radiation, collecting detailed geophysical data that will help our exploration team better understand the geology beneath the surface.

We appreciate that the low altitude and associated noise of the helicopter may have caused some disruption over the past few days, and we are grateful for the community’s patience and support as we continue to improve our understanding of the Maldon goldfield.

OUR COMMUNITY
OUR OPERATIONS

We’re progressing plans for a new Tailings Storage Facility at the Porcupine Flat Processing Plant, with detailed design work expected to be finalised by the end of August and site preparation works set to commence within the next week.

🔹 The new facility, known as TSF4, forms part of an approved Work Plan and Planning Permit and will provide additional storage capacity to support processing operations.

🔹 Initial works will include fencing the site, followed by earthworks and clearing of vegetation. Cleared trees will be retained, stored and seasoned on site for future community donation.

🔹 Access to the existing Processing Plant Viewing Platform will remain unchanged throughout the works, allowing visitors to continue viewing processing operations.

Tailings are the material remaining after gold is recovered during processing, and their safe and responsible storage is a vital part of processing operations. Tailings are stored 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’ll continue to share updates as work progresses on TSF4, helping keep our neighbours and the wider community informed about what’s happening here at Porcupine Flat.

Did you know…

There’s a wide range of activities that can take place across the Union Hill site and they don’t all operate to the same schedule.

Different activities have different permitted days and hours of operation, so while some work is limited to weekdays or Saturdays, other work may take place seven days a week.

Here’s a quick guide to what you might see or hear happening around Union Hill:

🚧 Site haulage of ore and/or waste material
🕑 Permitted hours: 7:30 am to 6:00 pm, Monday to Saturday

🚧 Above ground earthworks
🕑 Permitted hours: 7:30 am to 6:00 pm, Monday to Saturday

🚧 Maintenance and other low-impact activities
🕑 Permitted hours: 7:30 am to 6:00 pm, seven days a week

🚧 Geological works
🕑 Permitted hours: 7:30 am to 6:00 pm, seven days a week

🚧 Trucking of ore on public roads
🕑 Permitted hours: 7:30 am to 6:00 pm, Monday to Friday (public holidays excepted)

🚧 Underground operations
🕑 Permitted hours: 24 hours a day, seven days a week

🚧 Surface activities associated with underground mining operations
🕑 Permitted hours: 24 hours a day, seven days a week

🚧 Blasting activities
🕑 Permitted hours: 24 hours a day, seven days a week
🕑 Current operating hours: 7:30 am to 6:00 pm, seven days a week

So, if you notice activity at Union Hill on a Saturday or Sunday, it may relate to an activity permitted to take place seven days a week, while other works are limited to certain days.

While blasting is permitted 24 hours a day, seven days a week, at this stage we are undertaking blasting activities between the hours of 7:30 am and 6:00 pm. These hours reflect our current operations and may change as operations develop.

We hope this helps our neighbours and the wider community stay informed about what’s happening at Union Hill and what to expect at different times.

OUR COMMUNITY

An airborne magnetic and radiometric survey commenced yesterday, later than the planned early-August start due to weather and technical delays.

The survey is focusing on the northern part of the Maldon goldfield and is expected to be completed within seven days, weather permitting.

During the survey, you may notice a helicopter flying systematically across the area while measuring subtle variations in the Earth’s magnetic field and naturally occurring radiation. The helicopter, with registration VH-XGU, will be flown at an altitude of approximately 30 metres.

Magnetic and radiometric surveys are commonly used, non-invasive exploration tools, providing valuable geological data with no ground disturbance.

The data collected will help guide future exploration activities, assisting in identifying targets for further geological investigation.
