Up to 35% of cement can be pozzolan

Sunrise Resources PLC (LON:SRES) saw its shares surge over 45% higher today on news it has started to prepare samples of cement subsitute pozzolan for potential customers as drill assays confirmed commercial quantities at its CS deposit in Nevada.

Preliminary results showed thick intervals of pozzolan and perlite-pozzolan, while tests on material from the Tuff Zone, which has been given priority by Sunrise, showed it comfortably met the international standard.

In early morning trading, Sunrise Resources' shares leapt 46.7%, or 0.07p higher at 0.22p.

A number of meetings have been held with potential US customers for both perlite and pozzolan and samples are being readied to be submitted to interested parties for their internal laboratory testing.

Additional trenching also showed extensions of the Main Zone towards the Northeast Zone.

Sunrise added that the Pozzolan testwork has now moved onto extensive external certification, starting with the Tuff Zone samples.

Preliminary testing confirmed visual observations

Patrick Cheetham, Sunrise’s executive chairman, said the preliminary testing had confirmed the visual observations while the trenching programme has indicated important extensions to the Main Zone’s perlite and pozzolan.

We have prioritised pozzolan testing on the Tuff Zone and I am pleased to report that the preliminary results show that, in all cases, the pozzolan strength requirements of ASTM C618 required after 28 days curing have been exceeded after only 7 days curing.

The meetings with potential customers had been encouraging, he added.

Pozzolan can replace up to 35% of ordinary Portland cement in cement and concrete mixes.

The manufacture of Portland cement produces significant amounts of greenhouse gases, unlike natural pozzolan.

Perlite is a glassy raw material that can expand to 20 times in volume when heated.
