The three main types of waste streams and effluents generated in our projects are: 1.Hazardous waste (waste oils) 2.Inert waste (largely non-biodegradable, non-flammable and not chemically reactive) 3.Putrescible waste (containing organic materials such as food and wood wastes, which readily biodegrade within a landfill environment) Centaurus tracks all types of waste stream volumes and calculates the waste generation. In 2024, the volumes of waste generated from the projects were: hazardous waste1.7t, inert waste1.3t and putrescible waste0.9t. Of the inert waste stream, the Company maintains the segregation of recyclable wastes (plastic, paper, aluminium etc) prior to disposal, thus saving volumes of waste going to landfill. The waste generated at the JNP exploration site and at the offices, once segregated, is temporarily stored in separate bins before being collected for recycling and reuse by third party contractors. Waste oil from vehicle maintenance and installed water:oil separators is collected by a hazardous waste transport and disposal company. The waste oil is transported and disposed of offsite and is often used as a fuel source. The organic waste is composted and used in the Cana camp plant nursery. Regarding Greenhouse Gas (GHG) emissions, Centaurus adopts the following definitions to report against: 4Scope 1 Emissions - The total global direct emissions from sources owned or controlled by the reporting facility or business unity (Stationary combustion; Mobile combustion; Process emissions; and Fugitive emissions) 4Scope 2 Emissions - Indirect GHG emissions that the facility or business unit has caused through its consumption of energy in the form of electricity, heat, cooling or steam The air emissions resulting from the Companys exploration activities is carbon from diesel exhaust, power consumption and vegetation clearing.Given the nature of the Companys current activities, the amount of carbon emitted into the atmosphere is insignificant, with total Scope 1 and Scope 2 emissions of 267t of CO 2reported during the year from JNP. Data for carbon sinks has not been included.2024 CTM Sustainability Report Text_FINAL DRAFT 20Mar25.docxPage 17 of 38'
