[1] | The Group voluntarily changed its disclosure policy for exploration and evaluation assets to be disclosed separately as Exploration and evaluation assets rather than as part of Property, plant and equipment; similarly lease liabilities were classified separately from trade and other payables (refer to note 4(b)(i) and 4(b)(ii)). The new disclosure policies were adopted from December, 2020 and have been applied retrospectively.
