Dear Shareholder

Provision of Shareholder Documents and Information in Electronic Form

In line with the shareholder approvals granted at the Annual General Meeting of Hochschild Mining plc (''the Company'') on 4 July 2007, the Company now communicates with its shareholders electronically. This means that shareholder documents and information such as Notices of Shareholder Meetings and Annual Reports & Accounts are published on the Company's website www.hochschildmining.com unless paper form documentation is specifically requested.

Electronic communications result in cost savings to the Company and also reduce the environmental impact of printing large quantities of the Annual Report & Accounts.

Shareholders are required to consent individually to this method of publication; hence the reason for this letter.

There are three choices available to you.

• 1. If you would prefer to receive notification by post each time the Company places a statutory communication on its website, no further action is required in response to this letter;
• 1. If you would prefer to receive notification by email each time the Company places a statutory communication on its website, you can register your email address either via the share portal at www.capitashareportal.com or by completing and returning Part A of the enclosed form to our Registrars; and
• 1. If you would prefer to continue receiving hard copies of statutory communications issued by the Company, please complete and return Part B of the enclosed form to our Registrars.

Please note that if you do not register an email address or return Part A or Part B of the enclosed form within 28 days from the date of this letter, we will assume that you have consented to website publication and you will be notified by post each time shareholder documents and information are made available on the Company's website. As a result, you will no longer receive hard copies in the post unless we are instructed otherwise.

Yours faithfully

R D Bhasin Company Secretary
