In June 1981 the twin dredges 'Guaycura' and 'Pericue' were christened in Baltimore for Roca Fosforica Mexicana SA de CF (Rofomex) of Mexico. The Rofomex dredges were named after two local Indian tribes, "joining the ancient traditions of the peninsula with modern technology". The Ellicott Series 3000E electrically powered "Super-Dragon®" dredges were used in a phosphate mining project in LaPaz, Baja California, Mexico.
The project utilized 100 percent Mexican labor, dredging 2,000 tons of hard phosphate-bearing sand per hour, and transferring it to floating processing plants. Tailings were returned to the pond and the mineral underwent further processing in a shore-based plant.
Standard transportable 24" dredges converted to shore power electric for specialized mining. Dredges shipped fully assembled by heavy-lift ship.
Rugged construction accommodated very hard digging.
