- Sunrise Resources said it had successfully completed processing trials at its CS pozzolan-perlite fertilizer project in Nevada.

The company said it had also expanded horticultural-grade perlite in further customer trials.

Sunrise is progressing a low-capital-cost concept to produce a horticultural-grade raw perlite and by-product of finely-crushed natural pozzolan using mobile processing equipment.

Work was completed with equipment suppliers to trial mobile primary and secondary crushers and high-frequency screens to prove the concept.

A 7-ton bulk sample of perlite was processed to produce a horticultural-grade raw perlite and a finely-crushed perlite for sale as natural pozzolan.

A larger trial was planned for 100-ton bulk sample already collected to produce larger amounts of horticultural-grade perlite for supply to a wider range of potential customers.

'This is an important step in proving the concept for a low capital cost start for perlite and natural pozzolan production at the CS Project,' executive chairman Patrick Cheetham said.

'We have demonstrated that the perlite can be crushed and screened to the sizes required for expanding to horticultural grades of perlite using mobile processing equipment commonly used in the quarry industry.'

'This equipment is widely available for rent, lease or purchase, new or second-hand, which is consistent with our low capital cost concept.'

This should allow us to get into production quite quickly once permitting is completed later this year.'
