Environmental, social, governance (ESG) initiatives are further delaying mining projects while critical metals are in high demand, creating tension within the mining industry, says Matt Watson, founder of Precious Metals Commodity Management LLC.
The other problem is that metals necessary for the green transition are difficult to process, namely nickel, cobalt and rare earths.
On April 3, Watson recorded an episode of Green Rush with guests James Gavilan, principal of Gavilan Commodities, and Lyle Trytten, president of Trytten Consulting Services. The subject was ESG in the context of scaling responsibly mined minerals.
Watson pulled up a chart from the U.S. Geological Survey showing we will use all our nickel and cobalt reserves by 2050. It takes up to 17 years to develop a mine, longer if ESG criteria must be met.
“They're adding to the timelines, and unfortunately, I think we're getting into a genre of metals that are dirty,” he said, cueing up nickel processing expert Lyle Trytten.
There are two types of nickel deposits — sulfide and laterite. Sulfides tend to be in North America and Europe, whereas laterite nickel deposits are clustered around the equator. Indonesia is by far the largest nickel producer. Nickel mined there is processed using high-pressure acid leaching (HPAL), which generates less air pollution than traditional smelting but creates fine tailings (2-10 microns) that are difficult to dispose of.
Trytten said sulfide deposits are easier to handle from a pollution perspective, but “the reality is that we need nickel from a variety of sources. We're not going to bring it all from the sulfide deposits that we have in North America and Europe.” That means that, one way or another, the industry must deal with tailings.
“They're a necessary evil, and you're in these areas that have high rainfall, high seismic risks, and steep topographies,” he said. “There are no good answers, there's a succession of bad answers.”
Gavilan said his clients are seeking security in mineral supply, and that is shining a spotlight on problematic mining jurisdictions like Indonesia. He pointed to the recent explosion at a Chinese-owned nickel plant on Indonesia’s Sulawesi Island that killed 13 workers.
“This type of mining in Indonesia and other areas helps make the case greater when we look at clients that are operating in better jurisdictions,” he said.
Cobalt mining in the Democratic Republic of Congo has come under scrutiny due to the use of child labor, environmental degradation, and civil unrest.
Trytten said there are also no good answers regarding mining in the DRC, “except driving through the supply chains to understand where things come from, how they are developed, mined, processed, etc., what the full supply chain looks like and having that actually visible right down to the customer level.”
