The Spumoni mine is located near the headwaters of Brohm River, 12 kilometres north of Squamish. It is owned by Northwest Landscape Supply Co. Ltd. It quarries talus blocks of basalt for landscape use.

The property is underlain by flood basalts of the Garabaldi Group. These are typically flow layered, at metre scale, columnar jointed black aphanitic basalt. It usually weathers a rusty-tan colour. Development of the site began in 1995 with production three years later. Production figures are not available.
