A review of the mine plan for the zinc/lead project in Greenland has delivered an extra 90,000 tons of zinc over the first six years of production...

The project owner, the Australian miner Ironbark Zinc, announced to its shareholders on Monday that the review had brought the optimum scale of the project up to 3.3 million tons of zinc per year. The life of the mine has been established at 14 years.

According to the company, this additional output has been made possible thanks to new twin declines installed to access the main orebodies, which will allow for much improved metal recovery.

Ironbark’s managing director Michael Jardine commented on the review: “This study represents the first instalment of several reviews currently being undertaken to ensure that the feasibility study for the Citronen project is completely refreshed by taking advantage of the many changes in technologies, standards and pricing that have occurred since the original study work was completed in 2012”.

“These initial findings, focused on the mining operations, demonstrate the wisdom of this approach and serve to reinforce the magnitude of the opportunity that the Citronen ore deposit represents. These mining study results further de-risk the project by the adoption of updated mining practices, an optimised new mine plan and more efficient production schedule.”

Jardine added that the Citronen project is being positioned as a priority for investment among Ironbark’s major zinc projects, due to the site’s long mine life, its potential for substantial exploration, its valid mining licence, and the support available to Ironbark from base metal traders Glencore and Trafigura.

Offtake agreements with Glencore and Trafigura would allow around 70% of ore concentrate produced at Citronen to be committed.

While focussed on northern Greenland, Ironbark’s mineral assets in Australia comprise three base and precious metal projects in New South Wales.

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.
