{{#badges: CoalSwarm}} The Port of Guaymas is in Sonora, Mexico. A coal terminal has been proposed at the port.


The port lies on the shores of the Gulf of California off the Pacific Ocean in the southwestern area of the State of Sonora, Mexico, about 200 miles south of the border from the United States. The port sits at the mouth of the Río Yaqui and is surrounded by mountains.

Puerto (Port) de Guaymas is a shipping, manufacturing, commercial, and tourism center. Major exports include sulfuric acid, copper, wheat, and other crops grown in the region. In 2012 it was reported the port is planning an expansion that will extend the port into the bay between Guaymas and neighboring Empalme. The Mexican government will fund the expansion, but future terminals for minerals, oil, coal and grains will be leased to private companies.[1]

Coal exports

MEXPORT Coal & Minerals Terminal has proposed to build a US$700 million terminal at the Port of Guaymas. The project aims to ship 30 million tonnes a year to Asia, sourced from the US Powder River Basin and other mining regions in the Western region of the US.[2][3]

In April 2012 it was reported that Union Pacific was working with Mexican railroad Ferromex to possibly export coal through the Port of Guaymas, about 240 miles from the US border.[4]

Critics of the proposed export route through Puerto Guaymas point out that the rail journey for the PRB coal would be longer than the journey to the Westshore Terminals near Vancouver, British Columbia, and that shipping distance from Puerto Guaymas to Asian markets would also be longer than from Canada.[2][5]

The Port of Guaymas website shows the Union Pacific/Ferromex rail corridor that would be used to transport coal from the United States to Puerto Guaymas. Trains would cross the border at Nogales, Arizona.[6]

As of March 2018 there have been no developments on the terminal since its proposal in 2012.
