Sunrise Resources Plc (LON:SRES) has discovered more potential sources of natural pozzolan at its CS project in Nevada.
A new area named as the Tuff Zone, located 1.7 km southwest of the Main Zone, extends over 1.2 km and a width of 200m, with the area also containing perlite.
A further 22 mining claims have been staked to cover new targets, with the whole project area now covering 2.9 sq km.
Patrick Cheetham, executive chairman, said: "The newly identified Tuff Zone has a significant tonnage potential based on the large surface area mapped so far.
“There are good markets for both natural pozzolan and perlite in Nevada and the adjacent state of California.
“We expect to provide more detailed information on the commercial significance of the positive results we have announced to date when the project development concept study is completed in the next few weeks."
Perlite is used as an insulator in paint, plaster, concrete fillers and in soil aeration with its main characteristic that it expands hugely when heated.
Pozzolan, meanwhile, is a more environmentally friendly cement substitute.
