Over the last 40 years, iron ore prices have been decided in closed-door negotiations between the small handful of miners and steelmakers which dominate both spot and contract markets. Traditionally, the first deal reached between these two groups sets a benchmark to be followed by the rest of the industry.

05-06-2018Mankind started mining for precious metals between 20,000 and 40,000 years ago. For the last century, mining has been one of our planet's largest industries (it generated 683 billion dollars in revenue in 2018 alone). This only underscores the fact that our desire for precious metals and minerals has grown exponentially since we first started digging through the topsoil
