Shares in Sunrise Resources (LON:SRES) surged 14% on the day as the group staked claims over a second industrial minerals project - a pozzolan project - in Nevada, USA.
It comes after the group said last week it had leased out its County Line Diatomite claims to EP Minerals for 25 years.
The Pozz Ash project is now being assessed with a view to its use as a greener replacement for Portland cement in the manufacture of cement and concrete mixes.
Executive chairman Patrick Cheetham told investors: "Climate change legislation and pressures are driving strong interest in natural pozzolans and so we are very pleased to have identified this opportunity during recent prospecting in Nevada.
Speaking to Proactive, he added: "Cement is one of the main greenhouse polluters."
He explained how there were already other sources of pozzalan, for example from the ash from coal fired power stations but these sources were unevenly distributed regionally and becoming less abundant as such power stations are being phased out.
On the costs of exploiting the new site, he said: "Pozzalan is not a high value product but it's friable and free digging so it will be very cheap to mine and so it's really just an issue of transport costs to the cement plant."
Earlier the firm said the project had significant tonnage potential and aligned with its strategy to seek out potential cash generative industrial minerals projects at low cost - a strategy validated by the recent agreement with EP Minerals.
That lease agreement, announced last week, allows EP Minerals to continue its evaluation of the company's 109 claims for an 18 month period and the terms mean Sunrise receives a revenue-based royalty every six months from the start of production.
Cheethham told Proactive: "What we are essentially doing is piggy-backing on the back of EP Minerals' business."
They are experienced diatomite producers, and already have plants in Nevada, so this deal is a shortcut for Sunrise to get into production, he explained.
The production of cement is responsible for 5% of the global man-made carbon dioxide emissions with nearly one tonne of CO2 generated for each tonne of cement produced.
Sunrise said cement manufacturers are under strong pressure to minimise their carbon footprint and the use of pozzolan as a partial replacement for Portland cement in cement and concrete mixes is one way.
City broker Northland rates the shares a 'speculative buy', and said: "Pozzolan may well be something you have never heard of, but it is becoming an increasingly important environmentally friendly addition to cement manufacture.
"A Pozzolan is essentially a siliceous or siliceous and aluminous material that in finely divided form and mixed with lime and water at low temperature will form compounds with cementitous properties.
"The use of the material dates back to the Roman times but the significant reduction in the production of CO2 associated with its use compared to more traditional Portland Cement is driving the cement industry towards increased pozzolan consumption. An additional benefit of pozzolan is it strengthens and stabilises the cement improving its durability."
