Here you’ll find everything you need to know about our facility and the importance of silica in everyday life. 

About the Mine PPM Our Facility

PPM is located on Gold Mine Road, in the centre of Helidon Queensland, the site is located approximately 110 kilometres west of Brisbane with easy access to all main highways that provide a gateway to Brisbane, the Brisbane port and to other major cities.

Pleasure Point Mine is a sand quarry located in Helidon, having been measured to contain 40,921,600 tonnes and a high (94% unwashed and 97% washed) silica content. 

The silica content is suitable for a variety of uses including:

    • architectural high gloss finish stone for export
    • dimension stone for export and domestic use
    • landscaping and retaining wall boulders
    • road base
    • concrete aggregates and other general-purpose aggregates; 
    • cement & mortar grade sands
    • pipeline bedding, packing and ballast sands and coloured sands.


Since being purchased, the mine has seen an increased valuation from $5.2 million to $122 million.

The current mining lease and permit allows extraction of up to 1 million tonnes of material per year up until 2033. 

The full PPM resource is available for processing and offtake (40.0Mt). Currently there are no requirements to manage waste, overburden or spoil in the project plan due to the full resources being utilised.

The Importance of Silica

Silica, silica sand or silicon dioxide is used for a wide variety of applications, particularly in industrial processing. Silica itself is quartz that over time, through the work of environmental factors has been broken down into tiny granules.

Did you know speciality glass, like your mobile phone screens, are made from sand? Now imagine a world without these devices, we’ve all become accustomed to using our devices to communicate with our loved ones, do work, our banking and always be connected. Sand is the second most mined resource in the world, with demands both globally and domestically here in Australia. 

One of the areas where silica is used, is in all types of speciality glass which includes test tubes and other scientific tools, incandescent and fluorescent lamps, and television and computer CRT monitors etc. In fact, it’s also a crucial ingredient to construction aggregate.

Ultimately, the way in which silica sand is used is dependent on a variety of factors such as the chemical, physical and mechanical properties including colour, grain size, stability and strength. Part of these characteristics are dependent on the way in which the mineral is processed after the mining process. 

The nature of silica makes it much more durable and harder to wear down compared to regular sand. 

When you hear the word sand, you’ll likely to think of the beach or the desert. This form of the mineral will always contain a certain amount of silica but in amounts less than 95%. As this type of sand includes many ‘impurities’ such as iron and potassium it is more chemically reactive, hence the multiple textures.  Thus, regular sand is unable to lock together to create stable forms.
