OUR ENVIRONMENT
BASELINE SURVEYS  
& ASSESSMENT 
JAGUAR NICKEL PROJECT
Various baseline environmental programs 
were undertaken at the JNP throughout the 
year, including: 
	> Surface and groundwater quantity and 
quality monitoring programs 
	> Rainfall measurement
	> Social indicator monitoring 
In March 2025, SEMAS/PA issued the 
Installation Licence (LI) for the project, 
marking another important milestone towards 
the development of the JNP. 
Under the LI and upon commencement of 
construction, Centaurus must implement an 
Environmental Control Plan (ECP). This will 
comprise 39 environmental plans, 11 physical 
environment programs, 13 biotic environment 
programs (including sub-programs), nine 
socio-economic programs and six additional 
general programs, with the objective of 
controlling, monitoring, mitigating and 
managing the impacts associated with the 
Project. 
JAMBREIRO IRON ORE PROJECT
Centaurus’ environmental baseline surveys 
for the JIOP commenced several years 
ago and were renewed in 2023, with some 
environmental aspects continuously 
monitored. A series of surveys and technical 
activities were undertaken covering the 
physical, biotic and socio-economic 
environments of the region and, specifically, 
for the area where the Project is located. Data 
and results obtained are based on previous 
studies, including:
	> Flora and vegetation biodiversity
	> Fauna diversity and habitat
	> Surface and groundwater hydrology and 
quality
	> Social baseline data
Centaurus is progressing the Jambreiro 
environmental licensing with the regulatory 
agencies to obtain the necessary renewal of 
the Jambreiro licences. 
BIODIVERSITY 
Brazil is globally renowned for its great 
variation in ecosystems containing diverse 
animal, plant and fungi populations. Home 
to 60% of the Amazon Rainforest, which 
accounts for approximately one-tenth of all 
species in the world, Brazil is considered to 
have the greatest biodiversity of any country 
on the planet. It has the highest number of 
both terrestrial vertebrates and invertebrates 
of any country in the world, with the most 
known species of plants (55,000), freshwater 
fish (3,000) and mammals (689).  It also ranks 
third on the list of countries with the most bird 
species (1,832) and the second on the list of 
most reptile species (744).
JAGUAR NICKEL PROJECT
The Shannon Index (H’) is commonly 
used in ecology to represent diversity, 
which combines the richness (variety) and 
abundance (number of occurrences) of the 
identified species. The maximum H value 
under the Shannon Index is 5. The Shannon 
Index for the JNP fauna diversity is currently 
3.92, based on the fauna survey from 
2019/2020.
