Permit Environmental Protection Act 1994 Environmental authority EPML00928813 This environmental authority is issued by the administering authority under Chapter 5 of the Environmental Protection Act 1994. Environmental authority number: EPML00928813 Environmental authority takes effect on - 18 February 2026. Environmental authority holder(s) Name(s) Registered address DGR GLOBAL LIMITED Level 27, 111 Eagle Street BRISBANE CITY QLD 4000 Environmentally relevant activity and location details Environmentally relevant activity/activities Location(s) Resource Activity, Schedule 3,16: Mining gold ore ML3678, ML3741, ML3749, ML3752, ML3753, ML50059, ML50099, ML50148, ML50291, ML6622

Permit Environmental authority EPML00928813 Additional information for applicants Environmentally relevant activities The description of any environmentally relevant activity (ERA) for which an environmental authority (EA) is issued is a restatement of the ERA as defined by legislation at the time the EA is issued. Where there is any inconsistency between that description of an ERA and the conditions stated by an EA as to the scale, intensity or manner of carrying out an ERA, the conditions prevail to the extent of the inconsistency. An EA authorises the carrying out of an ERA and does not authorise any environmental harm unless a condition stated by the EA specifically authorises environmental harm. A person carrying out an ERA must also be a registered suitable operator under the Environmental Protection Act 1994 (EP Act). Contaminated land It is a requirement of the EP Act that an owner or occupier of contaminated land give written notice to the administering authority if they become aware of the following: - the happening of an event involving a hazardous contaminant on the contaminated land (notice must be given within 24 hours); or - a change in the condition of the contaminated land (notice must be given within 24 hours); or - a notifiable activity (as defined in Schedule 3) having been carried out, or is being carried out, on the contaminated land (notice must be given within 20 business days); that is causing, or is reasonably likely to cause, serious or material environmental harm. For further information, including the form for giving written notice, refer to the Queensland Government website www.qld.gov.au, using the search term `duty to notify'. Take effect Please note that, in accordance with section 200 of the EP Act, an EA has effect: a) if the authority is for a prescribed ERA and it states that it takes effect on the day nominated by the holder of the authority in a written notice given to the administering authority-on the nominated day; or
- Page 3
Permit Environmental authority EPML00928813 b) if the authority states a day or an event for it to take effect-on the stated day or when the stated event happens; or c) otherwise-on the day the authority is issued. However, if the EA is authorising an activity that requires an additional authorisation (a relevant tenure for a resource activity, a development permit under the Planning Act 2016 or an SDA Approval under the State Development and Public Works Organisation Act 1971), this EA will not take effect until the additional authorisation has taken effect. If this EA takes effect when the additional authorisation takes effect, you must provide the administering authority written notice within 5 business days of receiving notification of the related additional authorisation taking effect. If you have incorrectly claimed that an additional authorisation is not required, carrying out the ERA without the additional authorisation is not legal and could result in your prosecution for providing false or misleading information or operating without a valid environmental authority.

E1-2 All reasonable and practicable fire prevention measures must be implemented, including removal of grass and other materials within a 10m radius of the scrap tyre storage area. Flue Dust Containment Cell E2-1 The flue dust containment cell must be covered with a minimum of a 500 mm thick layer of grass- covered topsoil, or a low permeability layer such as bitumen or concrete. The layer must be constructed and maintained to ensure that there is a barrier between site users and flue dust and to minimise the potential for contaminants to enter the environment due to remobilisation by wind and surface water and leaching by infiltrating surface water. E2-2 No excavation or penetration of the approved capping may be carried out without written authorisation from the administering authority. E2-3 All persons who are proposing to undertake construction or excavation works within the Shamrock Leases must, prior to the commencement of such works, be provided with a plan indicating the location of the flue dust containment cell, and be made aware of conditions of this authority. E2-4 Unexpected Contamination. If during any site earthworks or excavation, offensive or noxious odours and/or evidence of contamination not previously detected is observed, site works must cease in that area and action must be taken to immediately abate the environmental harm. The administering authority is to be notified in writing within 2 business days of detection and advised of appropriate remedial action. Any remedial action is to be developed by an appropriately qualified and experienced person in accordance with Section 565 of the Environmental Protection Act 1994. E2-5 A site inspection is to be undertaken by a suitably qualified and experienced person at biennial intervals to ensure that capping and protective barriers associated with the flue dust containment cell remain in sound condition at all times in accordance with Condition (E2-1). E2-6 Records are to be kept of all inspections conducted to satisfy Conditions (E2-5) and forwarded to the administering authority on request.

Excavated soil must be managed and disposed of/ reused in a manner determined appropriate based on the results of this analysis. F1-2 Sampling and analysis of soil from excavations in contaminated areas must be representative and managed by a suitably qualified and experienced person. Contaminated soil must not be removed off-site without a disposal permit in accordance with Section 424 of the Environmental Protection Act 1994.

Inspection of Dams F2-5 High hazard dams containing hazardous waste shall be inspected by a Registered Professional Engineer (RPEQ) on or about 1st October but definitely before 1st November each year or at any time if alarming, unusual or otherwise unsatisfactory conditions are observed. F2-6 For each inspection, the engineer shall assess the condition of the dam and its foundations determine the hydraulic adequacy of the dam and assess the adequacy of the works with respect to dam safety.

Decommissioning of Dam - Objective F2-8 Dams containing hazardous waste must not be abandoned, must be decommissioned to a situation where water can no longer be stored in the dams and the dams and their contained waste(s) are stable, where after the dams are no longer dams and they become landforms on the operational land and must comply with the rehabilitation requirements of this Environmental Authority. Decommissioning of Dam - Documentation and Compliance F2-9 Decommissioning activities for dams containing hazardous waste must be documented in detail in the plan of operations under which the activities are to occur. Where the detailed documentation is not already contained in the Design Plan for the dam, the detailed documentation is considered to be an amendment to the design plan and must be submitted as an amendment to the design plan required by the Code of Environmental Compliance for Environmental Authorities for High Hazard Dams Containing Hazardous Waste. Exploration Activities F3-1 Exploration activities carried out on the mining leases which are the subject of this environmental authority must, as a minimum, be carried out in accordance with the Code of Environmental Compliance for Exploration and Mineral Development Projects.
