If quality characteristics of the receiving water at the downstream monitoring points exceed any of the trigger levels specified in Table E4 - Receiving Waters Contaminant Trigger Levels during a release event the environmental authority holder must compare the downstream results to the upstream results in the receiving waters and: a) Where the downstream result is the same or a lower value than the upstream value for the quality characteristic then no action is to be taken; or b) Where the downstream results exceed the upstream results complete an investigation in accordance with the ANZECC & ARMCANZ 2000 methodology, into the potential for environmental harm and provide a written report to the administering authority in the next annual return, outlining: i. Details of the investigations carried out; and ii. Actions taken to prevent environmental harm. Note: Where an exceedance of a trigger level has occurred and is being investigated, in accordance with E15(b) of this condition, no further reporting is required for subsequent trigger events for that quality characteristic.

The environmental authority holder must develop and implement a REMP for all stages of the activity to monitor, identify and describe any adverse impacts to receiving water environmental values, quality and flows due to the authorised activity. This must include monitoring the effects of the mine on the receiving environment periodically (under natural flow conditions) and while contaminants are being discharged from the site.

Permit OFFICIAL Environmental Authority EPML00770913 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). Mobile and temporary activities If you operate a mobile and temporary ERA, other than regulated waste transport, you are required to maintain a work diary. You must: - keep the work diary records for 2 years after the last entry; - inform the administering authority within 7 days of the work diary being lost or stolen; - record the information required in the work diary for each location within 1 day of leaving the location. Contaminated land It is a requirement of the EP Act that an owner or occupier of land give written notice to the administering authority if they become aware of the following: - the presence of, or happening of an event involving, a hazardous contaminant on the land that is causing, or is reasonably likely to cause, serious or material environmental harm (notice must be given within 24 hours); or - if the land is contaminated land - a change in the condition of the land that is causing, or is reasonably likely to cause, serious or material environmental harm (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 land (notice must be given within 20 business days). 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(1) 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 (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, in accordance with section 200(2) of the EP Act, the day that the EA takes effect may not be before: (a) if the authority is for a resource activity--the day the relevant tenure is granted to the applicant; or (b) if a development permit for a material change of use of premises under the Planning Act 2016 is necessary for carrying out an activity that related to the authority--the day the development permit takes effect; or

Permit OFFICIAL Environmental Authority EPML00770913 (c) if an SDA Approval under the State Development and Public Works Organisation Act 1971 is necessary for carrying out an activity that relates to the authority--the day the approval takes 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 EA. 27 August 2026 Signature Date Giles Bezzina Enquiries: Delegate of the administering authority PO Box 7230, Cairns QLD 4870 Environmental Protection Act 1994 Phone: (07) 4222 5352 Email: ESCairns@detsi.qld.gov.au

Permit OFFICIAL Environmental Authority EPML00770913 Obligations under the Environmental Protection Act 1994 In addition to the requirements found in the conditions of this EA, the holder must also meet their obligations under the EP Act, and the regulations made under the EP Act. For example, the holder must comply with the following provisions of the Act: - general environmental duty (section 319) - duty to restore the environment (section 319C) - duty to notify environmental harm (section 320-320G) - offence of causing serious or material environmental harm (sections 437-439) - offence of causing environmental nuisance (section 440) - offence of depositing prescribed water contaminants in waters and related matters (section 440ZG) - offence to place contaminant where environmental harm or nuisance may be caused (section 443). Other permits required This permit only provides an approval under the EP Act. In order to lawfully operate you may also require permits / approvals from your local government authority, other business units within the department, and other State and Federal Government agencies prior to commencing any activity at the site. For example, this may include permits or approvals with your local Council (for planning approval), the Department of Transport and Main Roads (to access State controlled roads), the Department of Natural Resources and Mines, Manufacturing, and Regional and Rural Development (to clear vegetation), and the Department of Primary Industries (to clear marine plants or to obtain a quarry material allocation). Obligations under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) Matters of national environmental significance (MNES) are regulated under the Commonwealth EPBC Act rather than under state legislation. You may need to submit a referral if your project potentially impacts any matters protected under the EPBC Act.

Details of the investigations carried out; and ii. Actions taken to prevent environmental harm. Note: Where an exceedance of a trigger level has occurred and is being investigated, in accordance with E15(b) of this condition, no further reporting is required for subsequent trigger events for that quality characteristic. E16 The environmental authority holder must develop and implement a REMP for all stages of the activity to monitor, identify and describe any adverse impacts to receiving water environmental values, quality and flows due to the authorised activity. This must include monitoring the effects of the mine on the receiving environment periodically (under natural flow conditions) and while contaminants are being discharged from the site. For the purposes of the REMP, the receiving environment is all underlying groundwaters and the waters of the Dawson River and connected waterways within 15km downstream of the release. The REMP should encompass any sensitive receiving waters or environmental values downstream of the authorised activity that will potentially be directly affected by an authorised release of contaminants. E17 The REMP must address (but not necessarily be limited to) the following: a) Description of potentially affected receiving waters including key communities and background water quality characteristics based on accurate and reliable monitoring data that takes into consideration any temporal variation (e.g. seasonality); b) Description of applicable environmental values and water quality objectives to be achieved (i.e. as scheduled pursuant to the Environmental Protection (Water) Policy 2009); c) Any relevant reports prepared by other governmental or professional research organisations that relate to the receiving environment within which the REMP is proposed; d) Water quality targets within the receiving environment to be achieved, and clarification of contaminant concentrations or levels indicating adverse environmental impacts during the REMP; e) Monitoring for any potential adverse environmental impacts caused by the release; f) Monitoring of stream flow and hydrology; g) Monitoring of toxicants should consider the indicators specified in Table E2 - Contaminant Release Limits to assess the extent of the compliance of concentrations with water quality objectives and/or the ANZECC & ARMCANZ 2000 guidelines for slightly to moderately disturbed ecosystems; h) Monitoring of physical chemical parameters as a minimum those specified in Table E2 - Contaminant Release Limits (in addition to dissolved oxygen saturation and temperature); i) Monitoring biological indicators (for macroinvertebrates in accordance with the AusRivas methodology) and metals/metalloids in sediments (in accordance with ANZECC & ARMCANZ 2000, BATLEY and/or the most recent version of AS5667.1 Guidance on Sampling of Bottom Sediments) for permanent, semi- permanent water holes and water storages; j) The locations of monitoring points (including the locations specified in Table E5 Receiving Water Upstream Background Sites and Down Stream Monitoring Points which are background and downstream impacted sites for each release point); k) The frequency or scheduling of sampling and analysis sufficient to determine water quality objectives and to derive site specific reference values within two (2) years (depending on wet season flows) in

Permit OFFICIAL Environmental Authority EPML00770913 accordance with the Queensland Water Quality Guidelines 2009. For ephemeral streams, this should include periods of flow irrespective of mine or other discharges; l) The tailored inclusion of dry season monitoring along Boughyard Creek to ensure water quality and potential impacts of shallow groundwater expressions during the dry season; m) Specify sampling and analysis methods and quality assurance and control; n) Any historical datasets to be relied upon; o) Description of the statistical basis on which conclusions are drawn; and p) Any spatial and temporal controls to exclude potential confounding factors. E18 A report outlining the findings of the REMP, including all monitoring results and interpretations in accordance with condition E17 must be prepared annually and made available on request to the administering authority. This must include an assessment of background reference water quality, the conditions of downstream water quality compared against water quality objectives, and the suitability of current discharge limits to protect downstream environment values. E19 All determinations of water quality must be: a) Performed by a person or body possessing appropriate experience and qualifications to perform the required measurements; b) Made in accordance with methods prescribed in the latest edition of the administering authority's Water Quality Sampling Manual; c) Collected from the monitoring locations identified within this environmental authority, within ten (10) hours of each other where possible; d) Carried out on representative samples; and e) Laboratory testing must be undertaken using a laboratory accredited (e.g. NATA) for the method of analysis being used. Note: Condition E19 requires the Water Quality Manual to be followed and where it is not followed because of exceptional circumstances this should be explained and reported with the results. E20 The release of contaminants directly or indirectly to waters: a) Must not produce any visible discolouration of receiving waters; and b) Must not produce any slick or other visible or odorous evidence of oil, grease or petrochemicals nor contain visible floating oil, grease, scum, litter or other objectionable matter. E21 The following information must be recorded in relation to all water monitoring required under the conditions of this environmental authority and submitted to the administering authority in the specified format with each annual return: a) The date on which the sample was taken; b) The time at which the sample was taken; c) The monitoring point at which the sample was taken; d) The measured or estimated daily quantity of the contaminants released from all release points; e) The release flow rate at the time of sampling for each release point; f) The results of all monitoring and details of any exceedances with the conditions of this environmental authority; and g) Water quality monitoring data must be provided to the administering authority in the specified electronic format upon request. E22 A Water Management Plan must be implemented and maintained that provides for the proper and effective management of the actual and potential environmental impacts resulting from the mining activity and to ensure compliance with the conditions of this environmental authority.

E24 Each year the environmental authority holder must undertake a review of the water management plan prior to the wet season (i.e. by 1 November) and a further review following the wet season (i.e. by 1 May the following year) to ensure that proper and effective measures, practices or procedures are in place so that the mine is operated in accordance with the conditions of this environmental authority and that environmental harm is prevented or minimised. E25 A copy of the water management plan and/or a review of the water management plan must be provided to the administering authority on request. E26 The environmental authority holder must ensure proper and effective measures are taken to avoid or otherwise minimise the generation and/or release of saline drainage. E27 The environmental authority holder must ensure proper and effective measures are taken to avoid or otherwise minimise the generation and/or release of acid and metalliferous drainage. E28 An erosion and sediment control plan must be developed by an appropriately qualified person and implemented for all stages of the mining activities on the site to minimise erosion and the release of sediment to receiving waters and contamination of stormwater. E29 The maintenance and cleaning of any vehicles, plant or equipment must not be carried out in areas from which contaminants can be released into any receiving waters. E30 Any spillage of wastes, contaminants or other materials must be cleaned up as quickly as practicable to minimise the release of wastes, contaminants or materials to any stormwater drainage system or receiving waters. E31 The administering authority and the environmental authority holder both acknowledge that the conditions for release of contaminants to Orange Creek, Boughyard Creek and the Dawson River in this environmental authority have been calculated without the benefit of the findings of projects proposed to be undertaken as per recommendations 2 and 3 of the Study of cumulative impacts on water quality of mining activities in the Fitzroy River Basin (April 2009). The administering authority may, based on the information provided in the study report when it becomes available, all relevant information available at the time and the regulatory framework applicable at that time, consult with the environmental authority holder about the conditions in the environmental authority concerning the treatment and disposal of waste water. The aim of the consultation shall be the meaningful review of the contaminant release limits imposed in this authority having regard to: a) The study results; b) Near field monitoring results; c) QLD Water Quality Guidelines; and d) Best practice environmental management. If this review leads to a change in the requirements on this environmental authority holder, this shall be advanced by way of an authority amendment or a Transitional Environmental Program and as is necessary or desirable. Groundwater E32 Contaminants must not be released directly or indirectly to any groundwater. E33 The taking of or interference with groundwater must not cause environmental harm to any groundwater dependant ecosystems.

Permit OFFICIAL Environmental Authority EPML00770913 E34 The Groundwater Management Program developed by an appropriately qualified person must be implemented and maintained by the environmental authority holder. E35 The Groundwater Management Program required by condition E34 must: a) identify potential sources of contamination and impacts to groundwater from the activity; and b) ensure that all potential groundwater impacts due to the activity are identified, mitigated and monitored; and c) document sampling and monitoring methodology; and d) ensure that adequate groundwater monitoring and data analysis is undertaken to achieve the following objectives: i. detect any impacts to groundwater levels due to the activity; and ii. detect any impacts to groundwater quality due to the activity; and iii. determine compliance with condition E45; and iv. determine trends in groundwater quality showing decreasing and increasing trends; and e) include an appropriate quality assurance and quality control program; and f) include a groundwater model which includes an assessment of current seepage rates and predicted post- mining seepage rates; and g) include a review process to identify improvements to the program that includes addressing any comments provided by the administering authority. E36 The Groundwater Management Program must be reviewed annually by an appropriately qualified person. The review must include at a minimum: a) an assessment that the Groundwater Monitoring and Management Program continues to meet the requirements stated in condition E35; and b) a review of all the historical groundwater data against the limits specified in Table E7 - Groundwater quality limits; and c) determine the representativeness of current groundwater conditions and suitability of Limit A and Limit B in Table E7 - Groundwater quality limits; and d) an assessment of the suitability of the monitoring network for groundwater specified in Table E6 - Groundwater monitoring locations and frequency to detect impacts from the mining activities; and e) where relevant information gaps or uncertainty are identified as pertinent to the accuracy of the investigations finding/conclusions, include recommendations and associated timeframes to address those information gaps and resolve uncertainty. E37 The Groundwater Management Program and annual review required under condition E36 must be provided to the administering authority annually from 30 January 2022. E38 The holder of the environmental authority must report the results and analysis of groundwater monitoring to the administering authority on request. E39 Groundwater levels must be monitored, and groundwater draw down fluctuations in excess of two (2) metres per year, not resulting from the pumping of licensed bores, must be notified as per conditions A10 - A11.
