Sunrise Resources PLC (AIM:SRES) chairman Patrick Cheetham said momentum is building behind the use of natural pozzolan as an alternative to man-made cement.
Cement production is responsible for 8% of global man-made CO2 emissions, he added, but the manufacture of pozzolan blends allows cement companies to reduce the embodied carbon in their products.
It also increases their cement production per ton of cement clinker capacity at a time when they are already operating at full capacity and cement process costs are soaring.
“We hold one of the few fully permitted and undeveloped natural pozzolan deposits in the western US, momentum is building for natural pozzolan, and we believe our CS and Hazen Pozzolan Projects are well placed to help industry in pursuit of its net-zero goals,” he said.
“In addition, we have a largely overlooked but valuable portfolio of precious and base metal projects that can provide additional growth opportunities in future. “
Sunrise posted a loss of £153,000 (£185,000) in the six months to end of March 2022.
