Confirming this quote: "Congo has three-quarters of the world’s cobalt, as well as monopolies on coltan and tungsten—which are vital for batteries and circuits, and enable devices to vibrate." It didn't pass a sniff test and I checked the numbers - it took about 10 minutes to confirm the errors via multiple sources

- Tungsten is mined in many countries with China, Russia and Vietnam being the largest producers. Not that those countries are fabulous, but DRC doesn't have a monopoly.

- As of 2022 Brazil plus Rwanda mine as much Coltan/Tantalum as DRC. Again, not a monopoly.

- The USGS estimates on Cobalt Reserves place DRC at slightly less than 50%. By production, the numbers are closer to 80% of current estimates. The 75% value seems to mix up stocks and flows.
