A new lead and zinc mine in China has been discovered in the far-western region of Xinjiang.

With almost 19 million tonnes of lead and zinc reserves, the mine in Hotan county becomes the largest lead and zinc mine in the country.

Zinc, has been a mined commodity since as far back as the 18th century.

Here are ten things you need to know about Zinc:

  1. Zinc, was used for making brass and medicinal purposes a good few centuries before it was identified as an element
  2. Pure metallic zinc wasn’t actually discovered until 1746, where it was credited to the hands of Andreas Marggfraf
  3. Zinc is, wait for it, the fourth most widely consumed metal in the world. The other three? Iron, aluminium and copper – but you knew that already
  4. One of the most common uses of zinc in the modern world is to combat rust. Yes, rust. While it may give it an old fashioned look with a bit of character, it is dangerous to steels. Zinc is used in zinc galvanising, what with its anti-corrosive properties and all. The process sees thin layers of zinc added to iron or steel to prevent rusting.
  5. Zinc is used for Zinc alloys. Combined with aluminium and copper, zinc alloys are used widely in the production of many components and die-casting fittings in the automobile manufacturing industry and the mechanical industry. For example, zinc alloy is used as a covering material for roofs
  6. Zinc alloys make up around 20 percent of all zinc applications in the world.
  7. Zinc is also used in batteries, but Alkaline batteries are more commonly used these days
  8. In 2016, the top three zinc producing countries are; China 4.9m MT, Australia 1.58m MT and Peru 1.37m MT
  9. Zinc as a mineral is naturally present in some foods, added to others and can be taken as a dietary supplement. Studies have shown that zinc may have antioxidant defects, is effective against infection and good for tissue repair.
  10. Foods which are a good source of zinc are red meats, poultry, oysters, seafood and whole grains

Vale’s $150mn investment in operations at Thompson, Manitoba will extend mine life by 10 years

Vale has announced a $150mn CAD investment to extend current mining activities in Thompson, Manitoba by 10 years while aggressive exploration drilling of known orebodies holds the promise of mining well past 2040.

Global energy transition is boosting the market for nickel

The Thompson Mine Expansion is a two-phase project. The announcement represents Phase 1 and includes critical infrastructure such as new ventilation raises and fans, increased backfill capacity and additional power distribution. The changes are forecast to improve current production by 30%.

“This is the largest single investment we have made in our Thompson operations in the past two decades,” said Mark Travers, Executive Vice-President for Base Metals with Vale. “It is significant news for our employees, for the Thompson community and for the Province of Manitoba.

“The global movement to electric vehicles, renewable energies and carbon reduction has shone a welcome spotlight on nickel – positioning the metal we mine as a key contributor to a greener future and boosting world demand. We are proud that Thompson can be part of that future and part of the low carbon solution.”

Vale continues drilling program at Manitoba

Coupled with today’s announcement, Vale is continuing an extensive drilling program to further define known orebodies and search for new mineralization.

“This $150mn investment is just one part of our ambitious Thompson turnaround story. It is an indicator of our confidence in a long future for the Thompson operations,” added Dino Otranto, Chief Operating Officer for Vale’s North Atlantic Base Metals operations.

“Active collaboration between our design team, technical services, USW Local 6166, and our entire Thompson workforce has delivered a safe, efficient and fit-for-purpose plan that will enable us to extract the Thompson nickel resources for many years to come.”

The Thompson orebody was first discovered in 1956 by Vale (then known as Inco) following the adoption of new exploration technology and the largest exploration program to-date in the company’s history.  Mining of the Thompson orebody began in 1961.

“We see the lighting of a path forward to a sustainable and prosperous future for Vale Base Metals in Manitoba,” said Gary Annett, General Manager of Vale’s Manitoba Operations.
