Antimony market

A cubic metre of stibnite: antimony economics

What does a near-surface discovery of near-pure antimony actually mean?

Here’s one way to think about the latest Howells Lake result.

One cubic metre of stibnite-rich material at 70.2% Sb contains roughly 3.25 tonnes of antimony.

At an antimony price of US$35,000 per tonne, that equals about US$114,000 of gross contained antimony value.

This theoretical illustration shows why grade matters.

Now the focus turns to the next holes: proving size, continuity, recoverability, and the path to market.
