Other companies have tried to develop natural pozzolan sources within California more local
than the CS Project to areas of demand but have failed for one of the following reasons;
� Bad timing � historical competition from fly ash.
� Permitting difficulties.
� Poor quality pozzolan.
6.4 Pozzolan Market Entry Strategy.
Natural pozzolan can be supplied as either:
� a crushed material (minus 1�) to exiting cement producers
� a finished ground pozzolan raw material to cement producers and ready mix supply
companies.
A cement company taking minus 1�crushed material would add the material to its
intermediate product, cement clinker, for intergrinding with the clinker to produce a Type 1P
Portland-Pozzolan cement. Such a cement is of interest to cement users who do not
separately source, store or mix a pozzolan.
Discussions with cement companies have already identified interest in this potential supply.
Similarly to the production and supply of a raw perlite product, this would involve a relatively
simple plant crushing and screening only and, in fact, would not require the same careful size
control that would be required for perlite production.
Whilst the market for a finished ground pozzolan will have a higher value and a larger market,
the supply of crushed pozzolanic material to cement producers provides a lower risk, low
capital and operating cost means to enter the market. Transporting crushed mine grade
materials in tipper trucks is, generally speaking, about half the cost of transporting a finished
pozzolan which usually requires a pneumatic truck for transport and unloading
It is estimated that there may be a demand of up to 110,000 ton per year of crushed raw
natural pozzolan that could be supplied from the CS deposit to Nevada, California and Utah
in the current market.
