CS NATURAL POZZOLAN PROJECT, NEVADA, USA

The CS Project is "mine-ready" with key operating permits already in place covering 14.5 million tons of natural pozzolan and 1.3 million tons of perlite. An additional area, the Northeast Zone, presents a large additional target with surface dimensions of 1.3km by 0.6km with a drilled thickness of over 40m from surface.

The CS Project natural pozzolan is a supplementary cementitious material ("SCM"), a partial substitute for Portland cement in the production of green cements and concrete.

The Company wishes to advise that, as part of ongoing discussions with potential customers, the Company has now provided a truckload sample, approximately 25 tons of CS natural pozzolan, to a potentially large customer for testing and market trials. Further information will be provided should this result in a material agreement.

Commenting today, Executive Chairman, Patrick Cheetham said:

"We are now starting to see some momentum building in the supplementary cementitious materials space. This was led by Eco Material Technologies' investment in the Kirkland natural pozzolan mine in Arizona, followed by the acquisition of the Geofortis' natural pozzolan operation in Utah by Ash Grove Cement and most recently by the US$2.1 billion acquisition of Eco Material Technologies by global buildings material group, CRH.

"I think these transactions underline that this is the right time to be involved in the natural pozzolan business and we are now seeing increased retail investor speculation in this space as highlighted by the recent steep rise in the share price of LSE-listed Atlas Metals Group, which recently announced a proposed £1 billion acquisition of an Australian pozzolan project."
