South32 working to reduce dust from manganese mine

The South32 share price has suffered on the ASX today.

Meanwhile, reports emerged that hair and nail samples from people residing nearby the company's Gemco mine have been found to contain high levels of manganese.

According to ABC News, the Anindilyakwa Land Council commissioned a report into the effects of dust from the manganese mine 8 years ago. Its CEO, Mark Hewitt reportedly told the publication that the report's results can't be released as it hasn't been published.

The publication states that the World Health Organisation has found inhaling manganese can cause "damage to brain functions controlling dexterity as well as the respiratory and reproductive systems".

However, the land council has decided to stop funding the research. Instead, it's working with the company to reduce the amount of dust impacting the community. ABC News quoted Hewitt as saying:

South32, to their credit, immediately embarked on extensive measures to prevent their manganese dust entering into the communities, which are in proximity to mining activities, and that work has been going on for three to four years, and it has definitely made a significant reduction.

The company has since begun spraying the site with water and avoiding the use of machinery nearby residential areas when wind conditions would allow dust to travel.  

South32 is also reportedly monitoring to make sure dust levels don't breach national air quality guidelines. The company's head of external affairs, Liam Stower was quoted as saying:

That monitoring has shown that the ambient dust in the community of Angurugu is below the National Environmental Protection Measure, the NEPM guidelines, so that gives us a high level of confidence about the health and wellbeing of our community.

South32 has been mining at Gemco for more than half a century. It's the largest Manganese mine in the world.
