WASTE MANAGEMENT &  
GREENHOUSE GAS (GHG) EMISSIONS
JAGUAR, BOI NOVO & 
JAMBREIRO PROJECTS
During 2025, Centaurus remained focused 
on opportunities to effectively manage and 
mitigate our waste streams and emissions. 
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 2025, the volumes of waste generated from 
the projects were: hazardous waste – 2.5t, 
inert waste – 0.6t and putrescible waste – 
0.8t. 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 site and at the 
offices is segregated and 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 are 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 Canaã camp plant nursery.
Regarding GHG emissions, Centaurus adopts 
the following definitions to report against:
	> Scope 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)
	> Scope 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 
Company’s exploration activities is carbon 
from diesel exhaust, power consumption and 
vegetation clearing.  Given the nature of the 
Company’s current activities, the amount 
of carbon emitted into the atmosphere is 
insignificant, with total Scope 1 and Scope 2 
emissions of 166t of CO2 reported during the 
year from JNP and BNP. Data for carbon sinks 
has not been included.  
Centaurus recognises the global importance 
of addressing climate change and remains 
committed to proactively managing climate-
related risks across its operations and 
development activities.
While the Company’s projects are expected 
to have a comparatively low carbon footprint, 
Centaurus continues to prioritise climate 
considerations within project planning and 
design. As part of this commitment, the 
Company reassessed the projected carbon 
footprint of the JNP following its decision 
to adopt a staged development approach, 
commencing with a concentrate-only 
processing phase.
