Lithium pegmatite mines can vary in depth depending on the location and size of the deposit. Some open pit lithium pegmatite mines can be several hundred meters deep, while others may only be a few tens of meters deep. Underground lithium pegmatite mines can also vary in depth, with some reaching depths of over 1,000 meters.
.

Examples of open pit lithium pegmatite mines include:
.

1. Greenbushes Lithium Mine in Western Australia, which is one of the largest hard rock lithium mines in the world and has an open pit that is approximately 300 meters deep.
2. Whabouchi Lithium Mine in Quebec, Canada, which has an open pit that is approximately 200 meters deep.
3. Pilgangoora Lithium-Tantalum Project in Western Australia, which has an open pit that is approximately 120 meters deep.

Examples of underground lithium pegmatite mines include:
.

1. Mount Marion Lithium Project in Western Australia, which has an underground mine that reaches depths of up to 400 meters.
2. Cinovec Lithium-Tin Project in the Czech Republic, which has an underground mine that is expected to reach depths of up to 500 meters.
3. Sonora Lithium Project in Mexico, which has an underground mine that is expected to reach depths of up to 300 meters.
