(Stock code: 1164) ANNOUNCEMENT PRICE SENSITIVE INFORMATION AND PROFIT WARNING

This announcement is made pursuant to Rule 13.09 of the Rules Governing the Listing of
Securities on The Stock Exchange of Hong Kong Limited.
Reference is made to the announcements dated 12 March 2012, 8 December 2011 and 4 August
2011 (the "Announcements") and the 2011 annual report (the "Annual Report") of CGN Mining Company Limited (the "Company"). The Company and its subsidiaries are collectively referred to as the Group (the "Group").
As disclosed in the Announcements, the Group discovered that since June 2011, there has been a substantial decrease in the sales of Osteoform compound calcium amino acid chelate food capsule ("Osteoform Food Product"). The food hygiene licence obtained by the Group was expired on 25
November 2011. Due to the change of relevant rules and regulations relating to food hygiene, the food hygiene licence for Osteoform Food Product was unable to obtain its renewal and therefore the Group had stopped the production of Osteoform Food Product in 2011.
As a result of the above events and after reviewing the available financial information of the Group, the Board expects that the profits of the Group for the three months ended 31 March 2012 will record a substantial decrement when compared with the corresponding three months ended 31
March 2011, as a result of the substantial decrease in the sales of pharmaceutical and food products like Osteoform Food Product, Osteoform Vitamins with minerals dispersible tablet and Madaus products.
The Company is in the process of preparing the unaudited quarterly results of the Group for the three months ended 31 March 2012. The information contained in this announcement is only based on the preliminary assessment by the Company's management according to the preliminary draft consolidated financial statements of the Group. Details of the Group's performance will be disclosed as and when the unaudited quarterly results for the three months ended 31 March 2012 are announced.
