The production of gold is a lengthy one that involves the process of mining, extracting and smelting. From the moment it’s dug out of the ground to when it become the gold we all know and love, watch out how the precious metal is made.

Mining

The process of gold mining is somewhat straightforward. Once a site is located, companies will construct mining operations (underground or surface) and begin searching for gold ore. The ore is then collected and separated depending on two categories -- low grade or high grade ore – and dispatched according to refinement.

Extracting

If the gold ore is low grade, which means it contains less additional minerals, it can be crushed into small pieces and soaked in cyanide dilute, dissolving the gold throughout the heap.

High-grade ore requires the grinding of ore into powder form with additional processing before cyanide dilute is used.

Smelting

Once the gold ore has been mined for and extracted, the process of turning it into pure gold begins. The ore is first extracted from the cyanide solution by combining carbon to absorb the gold with special chemicals used to strip the carbon from it. Last but not least, the gold is melted using extreme temperatures and then pressed into gold bars.

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.
