Mining company Gold Fields expects to be in a position to decide on the establishment of a wind power project at the South Deep gold mine, west of Johannesburg, in the third quarter of this year.
The project is currently undergoing scoping and feasibility and one of the key pieces of work has been around its environmental impact in general and its effect on a bat colony that exists in the nearby area in particular, Gold Fields CEO Mike Fraser said in response to Mining Weekly at this week's first-quarter results and environmental, social and governance (ESG) presentation.

"We believe, at an economic level, the South Deep wind project is viable but we just need to close out the full feasibility," Fraser said.
Since early 2023, a metrological tower has been in place at South Deep, measuring wind availability at a number of different heights above ground level.
"We should have all the data we need during the third quarter, and we'll be in a position, at that point, with all of the wind availability data, and the environmental-impact assessment (EIA) having been completed, to then make a decision," said Gold Fields VP environmental performance Andrew Parsons.
"We've now got a years' set of data and that work is more or less done. We'll be getting the report quite soon," Parsons added.
The EIA studies currently underway have got another three months or so to run.
BACKFILL ISSUE
South Deep is finding that as it backfills its underground workings, there is significant leakage of backfill materials, which is restricting access to stopes and the availability of future stopes.
Some 2 000 m of backfill, which is causing significant challenges across different working and open areas, needs to be cleaned up before advanced development can be achieved.
Graphs displayed showed the considerable re-handling that is having to be done.
"I almost look at this as an opportunity for South Deep," said Fraser. This is because if successful rework can be achieved, it sets South Deep up for getting well ahead of what's perceived to be possible at the mechanised, long-life mine.
"We're working with a number of experts to help us. It's hard for me to give you a clear answer as to when the backfill issue will be solved.
"We have forecast lower production this year because we expect this to take some time and if we can fix it, the opportunity is there for South Deep to get to where it needs to be as an asset," added Fraser, who will provide an update in the second quarter.
DECARBONISATION COMMITMENT
Johannesburg- and New York-listed Gold Fields this week reiterated its commitment to decarbonisation across the business.
"I do believe that Gold Fields is one of the leaders in our sector when it comes to mitigating its climate change impact. The programmes and projects that are underway to reduce our carbon footprint demonstrate our willingness to make a difference," said Fraser.
"We all have a role to play in combating climate change, and the impact that it is having on our planet, our mines, and our people.
"We can just see by the report that we've spoken about in terms of production, the impact of severe weather events is having and we certainly believe that that is going to become more prevalent," he said.
Targeted is a 30% net emission reduction and 50% absolute emission reduction by 2030, based on an assumed production volume of around 2.8-million ounces by 2028.
Like many other corporates, it is committed to net zero by 2050, against its 2016 baseline.
"We also re-baselined our Scope 3 emissions during 2023 and set a 2030 target to reduce our Scope 3 emissions by 10%, against our 2022 baseline.
"The Scope 3 emissions make up around 37% of our total emissions. And whilst not in our direct control, we will continue to be working with our major suppliers to achieve this target." Fraser added.
