Dear Mr. Superintendent.

      We have received your Ordinary Form Number 00427 dated January 14, 2005.
Regarding that Form and as requested by it, we may indicate the following:

        1.      On January 10, 2005, and as established in the "Environment
                Law", SQM Salar S.A., an affiliate of Sociedad Quimica y Minera
                de Chile S.A. ("SQM"), filed for its study before the COREMA of
                the II Region an Environmental Impact Study titled "Changes and
                Improvements of the Salar de Atacama Mining Operation Project"
                ("Project"). Said Project involves several changes and
                improvements in the mentioned operation and include those
                published by the "Estrategia" newspaper on January 13, 2005.

        2.      The future implementation of said Project will depend upon,
                among other things, its approval by the COREMA of the II Region
                and other relevant institutions, the mineral content of the
                respective brines, market conditions and future technological
                developments. The Project, if carried out, will involve an
                approximate amount of US$234.2 million that will span a period
                of 26 years, beginning in 2005, with an initial investment of
                US$35 million for the years 2005 and 2006. This initial
                investment is included in the "2004/2006 Capital Expenditure
                Plan" referred to in the previously indicated Form, and that
                will be financed with internally generated cash flows.







      We remain at your disposal to clarify any additional aspects that you may
deem relevant in relation to the above.

Yours truly,


                               SOCIEDAD QUIMICA Y MINERA DE CHILE S.A.

Dear Mr. Superintendent.

      We have received your Ordinary Form Number 00428 dated January 14, 2005.
Regarding that Form and updating what was exposed in the filings sent to you on
April 8 and May 12, 2004 -Essential Issue-, we may indicate the following:

        1.      SQM and Distrinor S.A. ("Distrinor") subscribed, on May 22,
                2001, a Natural Gas Supply Contract, of a "fixed nature",
                pursuant to which Distrinor, among other aspects, is required to
                supply and sell to SQM -for a period of 10 years beginning on
                June 1, 2001- all the natural gas the Company requires for "heat
                generation" at its industrial facilities located in Chile's
                Second Region and that the parties have estimated to be
                approximately 3,850,000 million Btu per year.

                Said contract is currently in effect, notwithstanding the
                reductions in the natural gas supply that Distrinor implemented,
                with SQM's consent, during some days of 2004 and that the latter
                was able to overcome with a higher production cost by using
                diesel as an alternative energy source.

        2.      The effects of any new reduction in the supply of natural gas
                will depend on, among other things, the volume of the reduction,
                its timing and the existence of industrial equipments that can
                use diesel or fuel oil instead of natural gas. In that sense,
                Distrinor has already informed SQM that there could be future
                temporary reductions in the supply of natural gas. On the other
                hand, SQM is in the period (summer) in which it has lower
                requirements of natural gas and has carried out or is about to
                carry out most of the necessary investments in its productive
                systems to replace -as an alternative fuel- part of its natural
                gas consumption with fuel oil and diesel. In fact, SQM's current
                projections indicate that it will be able to meet its annual
                production and sales programs.



         The potential lower consumption of natural gas and the consequent
         higher consumption of fuel oil and diesel will result in higher
         production costs that at this time and with the current available
         information is very hard to assess. SQM will, however, timely notify
         this Superintendence and the market about the financial effects that
         may arise as a consequence of any reduction in the natural gas supply
         contracted with Distrinor. This, regardless of the actions that SQM may
         exercise against Distrinor and third parties involved to request the
         fulfillment of their contractual obligations and indemnifications
         arising from the reduction in natural gas supply.

      We remain at your disposal to clarify any additional aspects that you may
deem relevant in relation to the above.

      Yours truly,
