[1] The operations were transferred to the current site at the turn of the 20th century, becoming known as Gwavas Quarry.

The full-scale aggregate operations ran throughout most of the century, reaching peak output in the 1960s and 1970s.

This connected the quarry with the south pier of Newlyn harbour, approximately ½ mile away to the east.

Stone was shipped from Newlyn to destinations around the Bristol Channel and the south coast and in later years to as far afield as Germany.

Penlee Quarry is a Site of Special Scientific Interest, designated in 1997,[2] noted for its geological formations and igneous rocks.
