Sierra Gorda

We always find better ways for our customers.

We look forward to doing the same for you.

What We Do

Get you just what you need, when you need it, wherever you are.

Sierra Gorda Molybdenum is a joint mine venture between partners KGHM and Sumitomo. Backed by a network of more than 100 offices in close to 70 countries and decades of collective experience, we create and deliver innovative, flexible solutions that are the right fit for your ever-evolving needs.

Our partners already handle over 13% of world’s molybdenum supply. With Sierra Gorda Mine, we’ve added a premier ore body and the largest single molybdenum mine in the world to our roster.

Our technology and experience allow us deep insights into the steel and alloy ecosystem to best manage materials for our customers. Using multi-year, multinational conversion capabilities through Molymet and others, we can satisfy all of your molybdenum needs.

We are singularly focused on the steel and alloy markets – your markets – to fulfill your long-term visions instead of managing by short-term trends. We listen to you to create reliable, custom supply solutions tailored to your business, and to learn about your specific needs so our plan evolves as your business moves forward. We work together to help you capitalize on every opportunity today and tomorrow.
