This quarry, also known as Lottah Road Quarry, Fieldwicks Quarry or the Weldborough Pass Quarry, is an operating road metal quarry located in Tertiary basalt on Lottah Road near Weldborough Pass.

Known for particularly nice gmelinite, natrolite, thomsonite and analcime in blocky, vesicular basalt, and also anorthoclase-sanidine rich granulite and lherzolite/peridotite xenoliths in surrounding and overlying massive to columnar basalt.

Site is under an active mining lease and permission to enter is required from the Tenement Holders, No public Access.
