JAMBREIRO IRON ORE PROJECT
The local rivers of the JIOP were sampled to collect baseline water 
quality data. This is useful when comparing water quality around the 
JIOP site once the project is in operation to pre-development baseline 
values. Any adverse changes in water quality can be acted on with 
further management intervention. Sixteen sampling points were 
tested, with most sampling points recording naturally high values of 
many parameters that exceed the National Water Quality Standards, 
including: iron, aluminium, cadmium, copper, manganese, fluoride, 
phosphorus, E.coli, turbidity, oxygen, biochemical oxygen demand 
(BOD5), nickel, cobalt, chrome and zinc. 
Flow rates for the two primary rivers around the JIOP from 2020 
through to 2025 are shown in the following box plots. The yellow stars 
are the 2025 monthly averages. Differently from the Jaguar Project, 
at Jambreiro, the 2025 flow rates at the two monitoring stations were 
within the first quartile as the precipitation in 2025 was below average.
