1. The resources/reserves for the year are based on the equity method, and all relevant volumes of projects/mines are calculated as per the Group’s actual shareholding ratio; and resources include reserves.

2. The Group completed the acquisition of the 3Q Lithium Brine Project in January 2022 and obtained lithium resources (lithium carbonate).
