Evidence: Wheal Eliza Mine was an unsuccessful copper and iron mine on the River Barle near Simonsbath on Exmoor in the English county of Somerset. The mine was originally called Wheal Maria, then changed to Wheal Eliza. The first mining activity on the site may be from 1552. It was a copper mine from 1845–54, although no copper was extracted, despite samples showing 60% metallic ore. It was then examined by Henry Schneider, of Schneider Hannay & Co which became the Barrow Hematite Steel Company, during 1856-57 for iron although none was found.
