The mission of the mining industry is to dig up valuable commodities and sell them. Many of those commodities -- gold, silver and iron ore -- are used in everyday items from jewelry and tableware to iPhones and circuit boards. And while the Earth provides some of the most lucrative minerals and metals known to man, it also produces some of the most dangerous.

The following five minerals, although mesmerizing and beautiful, have the potential to kill you.

1. Cinnabar

Cinnabar is visually stunning. It is bright scarlet to brick red in color and resembles quartz in its symmetry and optical characteristics. Overall, it's a gorgeous mineral to look at.

It’s also the deadliest.

Cinnabar (otherwise known as mercury sulphide) is the single most toxic mineral known to man. Generally found in large quantities and in non-metallic crystals around the world, it has been a primary source for mercury since the earliest days of civilization.  The problem with Cinnabar, is when oxidized it produces methyl and dimethy mercury, two toxic compounds that cause terminal damage to the nervous system.

2. Torbernite

Don’t let its beauty fool you. Torbernite is a radioactive mineral from hell.

The rich green crystals, which occur as secondary deposits in granite, contain uranium and have the ability to produce radon gas capable of causing lung cancer. Although the bright green crystals are striking to look at, they’re an obvious factor in identifying radioactivity.

3. Crocidolite

Otherwise known as blue asbestos, crocidolite is a death sentence as the exposure of this fibrous mineral causes fatal diseases including lung and mesothelial cancer.

Mined mostly in South Africa, Bolivia and Australia, this mineral was once widely used for an array of commercial and industrial applications due to its intense resistances to heat. Between 1943 and 1966, the mining of crocidolite killed more than 1,000 miners and residents in the town of Wittenoom in the Pilbara region of Western Australia.

4. Stibnite

Although stibnite does resemble silver in some fashion, it’s actually antimony sulfide, which means those sword shaped crystals have the powers to kill you.

The mineral, which was once used for producing eating utensils, killed thousands of people before it became known that use of the mineral caused fatal food poisoning. Stibnite should be handled with immense caution.

5. Quartz

Believe it or not, quartz is not your friend. While it may be the second most common mineral on Earth, when grinded up and inhaled, this devil of a mineral will cause difficulties in breathing and eventual lung cancer.

Specific industries like mining, abrasives and glass manufacturing have all implemented strict guidelines by OSHA dictating workers wear fumigators to limit their intake.

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.
