Mount Morgan Mine Upper Mundic Gully TSF EA Amendment

features) have a clear boundary demarcating the spatial extent of a polygon or polyline. In the case of the surface exploration mine features, which are point features located within a much larger mine domain, progressively certifying the rehabilitation of each point feature would also apply to the polygon underneath. This is considered a perverse outcome as the progressive certification can not apply to two separate domains that occupy the same physical area. The progressive certification process articulated in the Progressive Certification for Resource Activities Guideline (ESR/2022/5900 Version 1.02) states that the content of a progressive certification report must, amongst other things, include GPS Coordinates of the corners of the certification area or metes and bounds of the perimeter of the certification area. As the size of the boreholes are estimated to be between 50-200mm in diameter, it is not considered practical to obtain GPS coordinates of the corners of the disturbance. Removal of the exploration mine domain does not prevent the EA holder from undertaking any future exploration works at the mine features listed in Table A1 as condition A14 of the EA states the following: “ A14 All exploration activities carried out at the licensed place must comply with each of the Standard Environmental Conditions contained in the most recent version of the Eligibility criteria and standard conditions for exploration and mineral development projects -ESR/2016/1985 ”. There are no impacts on any environmental values and this proposed amendment does not significantly increase the level of environmental harm caused by the relevant activity. 2.2.3 Justification for Proposed Amendment 3 The justification for the proposed amendment is that the maximum value currently in the EA was either erroneously applied for or erroneously transposed into the EA during a previous amendment. The maximum value of 11,52,416m 3 is incorrect and the EA should be amended to authorise the correct value of 11,532,416m 3 . The International System of Units promotes decimal separators to demarcate a factor of 1,000. It is abundantly apparent that the value of 11,52,416 incorrectly provides for a decimal separator of 100 associated with the numbers “52”, further supporting that the number “3” was erroneously omitted. There are no impacts on any environmental values and this proposed amendment does not significantly increase the level of environmental harm caused by the relevant activity. A revised Table H2 has been provided within Section 2.3.2 of this report. 2.3 Proposed Conditioning Proposed conditions to support the amendments are provided within this section of the report. Items proposed to be removed from the EA are crossed out whilst items for inclusion in the EA are highlighted in red. The proposed conditions have been organised into the following categories for ease of understanding: ∕ Section 2.2.1. Conditions within the EA proposed for inclusion and amendment; ∕ Section 2.2.2. Tables within the EA proposed to be amended; and ∕ Section 2.2.3. Figures within the EA proposed to be amended. Conditions within the EA Proposed modifications to existing EA conditions and proposed new conditions for inclusion in the EA are provided in Table 5. 2.3.1
