Santiago, Chile, September 11, 2017 – Sociedad Química y Minera de Chile S.A. (“SQM” or the “Company”) (NYSE: SQM; Santiago Stock Exchange: SQM-A, SQM-B) announced today that the Company and its subsidiary SQM Australia Pty Ltd (“SQM Australia”), have signed a purchase agreement with MH Gold Pty Ltd, Montague Resources Australia Pty Ltd and Kidman Resources Limited (“Kidman”, all together as the “Sellers”) to acquire 50% of the assets in the lithium mining project called Mount Holland, located in the State of Western Australia, Australia (the “Agreement”). The Agreement is subject to compliance with usual terms and conditions for this type of transaction, including but not limited to the granting of government approvals for the transfer of mining property (the "Conditions").

Pending compliance with the Conditions, SQM Australia has committed to grant Kidman up to US$21.5 million in credit (“Credit”) which will be used by Kidman to continue the development of the Mt. Holland project.

Once the Conditions are met, SQM Australia will pay the Sellers a price of (a) (i) US$5 million, plus (ii) US$10 million in capital contributions to the project on behalf of the Sellers and (b) (i) a deferred price amounting to US$25 million, plus (ii) US$30 million in capital contributions to the project on behalf of the Sellers. This price is subject to certain adjustments described in the Agreement, including the repayment of the Credit. SQM Australia, has also committed to make capital contributions of US$10 million and US$30 million, together with the contributions from the Sellers, to finance the development of the project.

In compliance with the Conditions, SQM Australia and the Sellers will sign, among others, a joint venture agreement for the development, construction and operation of the mining project, a concentration plant and a refining plant to produce lithium carbonate and lithium hydroxide, and the agreements allowing said joint venture to explore and exploit lithium on the mining property of the Sellers not included in the Agreement.

Patricio de Solminihac, CEO of SQM, commented: “We are very pleased to have finalized the documentation required to begin this partnership with Kidman. We are convinced that the capabilities we have developed in over 20 years producing and commercializing lithium products, will be fundamental to successfully develop this project together with our partners”.

Then he continued: “Mount Holland enters our portfolio of lithium projects in Chile and Argentina, as a very low-cost project with large reserves. We continue to see strong fundamentals in the growth of this market, and that encourages us to continue looking for new projects, where we can add value using our experience and capabilities.”
