Dresserite is a hydrous barium aluminum carbonate (Jambor et al., 1969). The original description suggests that dresserite is the barium analog of dundasite, although the formulae of the two species differ in water content. The mineral name honors John A. Dresser (1866-1954), Canadian educator and geologist who contributed to the study of the Monteregian Hills, one of which is this locality.

Dresserite forms translucent spheres to 2.5 mm in a quartz lined cavity. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
