AuRico Gold
Canadian intermediate gold mining and exploration company with gold, silver, and copper assets in Canada and Mexico.
Last updated August 26, 2026
Overview
AuRico Gold was a Canadian intermediate gold mining and exploration company whose principal assets were located in Mexico and Canada. The company evolved through several corporate identities before adopting the AuRico Gold name in 2011. It was incorporated as Golden Rock Explorations, Inc. in 1986, became Gammon Lake Resources in 1998, changed its name to Gammon Gold in 2007, and rebranded as AuRico Gold in May 2011. The name combined “Au,” the chemical symbol for gold, with “Rico,” a Spanish word meaning rich. The company’s early development centered on Mexican exploration and mining opportunities. In 2004, the business moved beyond exploration and began producing gold. Its Mexican portfolio included the Ocampo operation in Chihuahua, the El Chanate mine in Sonora, and the Guadalupe y Calvo gold and silver project. Ocampo was acquired from Bolnisi in 2003 and entered production in 2007. It comprised an open-pit mine and underground workings, supported by a mill designed to process more than 3,000 tonnes of ore per day. El Chanate, operated through a Mexican subsidiary, also began production in 2007 and produced both gold and silver. AuRico expanded through a series of acquisitions. In August 2006, it completed the approximately $451 million acquisition of Mexgold Resources, bringing the Guadalupe y Calvo project into its portfolio. In 2011, it acquired Capital Gold for approximately $408 million after approval by Capital Gold shareholders. That transaction added the El Chanate mine and the Orion gold project in Mexico. The company then agreed to acquire Northgate Minerals in August 2011 in a transaction valued at approximately C$1.46 billion. The combination transformed AuRico from a company focused exclusively on Mexico into a broader intermediate producer with major Canadian exposure, including the Young-Davidson mine in Ontario and the Kemess project in British Columbia. The Northgate transaction also materially increased AuRico’s gold resources and reserves. Young-Davidson, near Matachewan, Ontario, became one of the company’s most important Canadian assets. The property was described as having close to three million ounces of gold reserves and an estimated mine life of about 15 years. AuRico also advanced the Kemess Underground project near the former Kemess mine in British Columbia and maintained other exploration interests, including a gold project in the Mount Ida region. AuRico Gold remained a diversified precious-metals producer rather than a single-mine operator. Its business covered exploration, mine development, extraction, processing, and the production and sale of gold and silver, with copper exposure associated with certain projects. Its Mexican operations supplied established production, while the Canadian assets provided a larger long-term development and production platform. In 2015, AuRico Gold merged with Alamos Gold in a transaction valued at approximately C$1.5 billion. AuRico shareholders received about half of the ownership of the combined company, which continued under the Alamos Gold name. The Kemess project was separated into AuRico Metals as part of the transaction and was later acquired by Centerra Gold in 2017. AuRico Gold therefore no longer exists as an independent operating brand, although its former assets and corporate history continued through successor companies.
History
AuRico Gold originated as Golden Rock Explorations, Inc., incorporated on February 23, 1986. The company adopted the name Gammon Lake Resources in 1998 and initially focused on exploration. Its principal growth path developed in Mexico, where the company built a portfolio of gold and silver opportunities and entered production in 2004. The Ocampo property was acquired from Bolnisi in December 2003 and became a producing operation in 2007. Located in Chihuahua, Ocampo combined an open pit with underground mines and included an on-site processing mill. Its ore was associated with epithermal mineralization, and the property produced both gold and silver. The company also developed El Chanate in Sonora, which began production in May 2007. El Chanate was operated by a Mexican subsidiary and covered exploration, extraction, processing, and commercialization of gold and silver minerals. On June 18, 2007, Gammon Lake Resources changed its name to Gammon Gold. The company continued to expand through acquisitions. In August 2006, it completed the acquisition of Mexgold Resources for approximately $451 million, adding the Guadalupe y Calvo project in Mexico. In April 2011, it acquired Capital Gold for approximately $408 million following shareholder approval. Capital Gold contributed the El Chanate mine and the Orion project. The company adopted the AuRico Gold name in May 2011. The new name referenced gold through the chemical symbol Au and used the Spanish word “Rico,” meaning rich. The rebranding coincided with a broader strategic shift from a Mexico-focused exploration and production company toward a larger, geographically diversified intermediate producer. That shift accelerated with the August 2011 acquisition of Northgate Minerals for approximately C$1.46 billion. Before this transaction, AuRico had operated only in Mexico. Northgate brought Canadian assets into the group, most notably Young-Davidson in Ontario and the Kemess project in British Columbia. Young-Davidson was described as having close to three million ounces of gold reserves and an estimated mine life of approximately 15 years. Kemess Underground represented an advanced development opportunity near the former Kemess mine and was supported by existing regional infrastructure. Following the Northgate transaction, AuRico’s portfolio included two Mexican operations, one Canadian operation, and several advanced development and exploration properties. Its activities covered gold and silver production, mine development, mineral exploration, and associated copper exposure. The company’s Mexican operations provided established production, while Young-Davidson and Kemess strengthened its longer-term Canadian growth profile. AuRico Gold ceased to exist as an independent company after its 2015 combination with Alamos Gold. The transaction was valued at approximately C$1.5 billion, and AuRico shareholders held about 50 percent of the combined business. The surviving company operated under the Alamos Gold name. As part of the arrangement, the Kemess project was separated into AuRico Metals, which Centerra Gold later acquired in 2017. AuRico Gold’s corporate identity was therefore retired, while its assets and projects continued under successor ownership.

Products and positioning
Intermediate precious-metals producer combining operating mines in Mexico with Canadian production and advanced development assets.
GoldPrecious metals
Gold was AuRico Gold’s principal commodity and the basis of its intermediate-producer strategy. The company produced gold from Mexican operations including Ocampo and El Chanate and later added the Canadian Young-Davidson operation through the Northgate Minerals acquisition. Its portfolio combined current production with exploration and development assets intended to support longer-term gold output.
SilverPrecious metals
Silver was produced alongside gold at Mexican properties, particularly Ocampo and Guadalupe y Calvo. At Ocampo, the orebody and processing system supported both gold and silver recovery, making the operation a polymetallic precious-metals asset rather than a gold-only mine.
CopperBase metals
Copper was an associated commodity within parts of AuRico Gold’s broader mining and development portfolio. It was not the company’s principal positioning, which remained centered on gold and silver production and exploration.
