Sunrise Resources completes concept trials at CS deposit in Nevada

AIM-listed mining group Sunrise Resources has successfully wrapped up proof of concept trials for a horticultural grade of perlite from its CS deposit in Nevada.

Sunrise said a seven-tonne bulk sample of perlite was processed to produce a horticultural grade raw perlite and a finely crushed perlite for sale as natural pozzolan.

The horticultural grade raw perlite product was then expanded successfully in a customer's commercial-scale plant.

Looking forward, Sunrise said it was progressing a low capital cost concept to produce horticultural grade raw perlite and finely crushed natural pozzolan using mobile processing equipment.

Sunrise also noted that it had a larger trial planned for a 100-tonne bulk sample already collected to produce larger amounts of horticultural grade perlite for supply to a wider range of potential customers.

Chairman Patrick Cheetham said: "The test was primarily designed to provide operating data for the raw perlite processing rather than samples for expansion testing so it is a bonus that we have now been able to complete a further successful commercial-scale expansion trial with a second customer."

As of 1125 BST, Sunrise shares had shot up 26.94% to 0.11p.
