LETTER TO:        ELEMENTIS

We act as an Investment Manager for a number of large institutional investors
and for a number of commingled funds. In acting for our Clients, we are given
full discretion over the investments, and are empowered to vote on their behalf.
However, we do not act as their Custodian, and therefore shares are not held in
our name, but in the nominee name of their Custodian Bank.

Recent purchases of shares in your company by ourselves, on behalf of our
clients, have resulted in our having control over the following shares (also see
below):

SILCHESTER:                 47,692,570               Ordinary Shares

Our records show that you have the following shares in that class

ELEMENTIS:                 431,400,000               Ordinary Shares

As such, we exercise control over 11.06% of the shares of that class.
