Air quality in Mount Isa
Emissions generated by our operations at Mount Isa Mines are monitored and managed around the clock—we check for sulphur dioxide, dust and other particulates that can affect air quality.

Alternately, our Air Quality in Mount Isa (AQMI) app enables you to check current air quality at any time on your smartphone. To download the app, search for 'AQMI' in iTunes or Google Play.
Improvements to air quality control
Mount Isa Mines’ Air Quality Control Centre was established in 1975 and is continually improved as scientific findings and new technologies emerge.
We review engineering approaches, operating procedures and monitoring programs for ways to reduce emissions. We also operate and monitor more air quality sensors than required by our Environmental Authority (EA) to provide additional information to guide our approach.
In line with our Environmental Authority (EA) regulated by the Queensland Government, we measure and track air quality through:
- short-term hourly results
- daily average results
- annual average results.
In addition to our rigorous internal monitoring and auditing processes, the Queensland Government Department of Environmental Science (DES) has independent access to Mount Isa air quality monitoring network data, with information provided hourly and automatically.
DES regulates our performance and is responsible for ensuring we comply with the strict conditions of our EA and all other relevant environmental legislation.
We aim to perform better than the limits in our EA to maintain compliance and to minimise impacts to the community where we work and live.
We encourage Mount Isa residents to review air quality results:
These results focus on managing sulphur dioxide emissions averaged over a 24-hour period of exposure.
Under our EA, daily average sulphur dioxide concentration must stay below 230 micrograms per cubic metre of air 99% of the calendar year. We cannot exceed a daily average sulphur dioxide concentration of 230 micrograms per cubic metre of air for more than three days at any station in Mount Isa.
Our monitoring results are calculated as percentile values at each monitoring location on a calendar year basis with averaging times based on whole clock hours and calendar days.
We encourage Mount Isa residents to contact our Community Feedback Hotline on 1800 982 982 if there are any questions or concerns about emissions from our operations.
