GCM MIning Corp is a Canadian-based gold and silver exploration, development and production company with its primary focus in Colombia. Gran Colombia is currently the largest underground gold and silver producer in Colombia with several underground mines and two processing plants in operation at its Segovia and Marmato Operations.


We are continuing to expand and modernize our high grade production stage Segovia Operations. Recently extended Segovia mine life to 2026; further upside in resource expansion and exploration assets. In recent years, GCM has successfully implemented a number of cost savings initiatives, bringing its All-In Sustaining Cost (AISC) to US850 per ounce in 2016 and expected to be below US900 in 2017.


‘Beyond Gold’ Video Premiere





GCM MIning is building the leading Colombia focused gold producer. The Company is building a strong production growth profile through exploration, development and bringing to production gold projects in Colombia. The Company’s focus is on the development of the Segovia Operations and Marmato projects to generate strong cash flows in the short, medium and long term.


To be successful, GCM Mining must also be a positive agent of change for the communities where it operates. The Company can only succeed if the communities are changed in a positive way and share in that success. GCM’s success will drive positive change in the communities; positive changes in health and safety, wages, pensions, the environment, economic growth and diversity, education and stronger communities.


The Company’s third focus is Valuation Growth. The GCM team believes strongly in the Company’s potential for great success and seeks to build shareholder value by having a great plan, executing through hard work & collaboration, and by achieving targets.

Why Colombia?


Colombia is a country of opportunities with a growing economy, one of the lowest inflation rates in Latin America and free trade agreements with eight trading partners including the USA, European Union and more than 100 designated free-trade zones. Colombia’s government is very supportive of foreign investment and it has the best investor protection in Latin America, 6th worldwide, according to the World Bank (2013). Mining is a significant sector in the Colombian economy and one of the country’s largest export sectors.

GCM produces gold from the Segovia Operations, an area of approximately 9,000 hectares in the Segovia-Remedios mining district of Antioquia. These high-grade mines have been in continuous operation for over 150 years and over that time have produced more than an estimated 5 million ounces of gold. The Segovia Operations include the El Silencio, Providencia and Sandra K underground mines in the Municipality of Segovia, and the Carla underground mine in the Municipality of Remedios, located approximately 10 km southeast of the Segovia mines. Mining operations incorporate both Company-operated areas and an artisanal miner model that contracts local third party miners to work in GCM’s concessions and to deliver the ore to GCM’s mill for processing.


Since taking control of the assets in 2010, Gran Colombia has initiated an extensive exploration and drilling program around the existing mines to identify new resources to be able to expand production and has commenced exploration in new areas of its concessions to identify potential new production areas. Simultaneously, the Company is in the midst of an extensive modernization program at the historical mines to introduce mechanization, to improve production efficiency and safety, and to reduce its all-in sustaining costs.

1 No open pit Mineral Resources have been declared. Derived from the Company’s Press Release dated October 4, 2017 which will be supported by a NI 43-101 Mineral Resource Estimate which will be published and filed on the Company’s website and SEDAR profile.



Acquired in the 2011 merger with Medoro, the Marmato Project contains total estimated resources of approximately 8 million ounces of gold and almost 38 million ounces of silver located in the Caldas department in the heart of the Middle Cauca gold district. The Marmato Project has excellent infrastructure, being located by the Pan American Highway with access to Medellin to the north and Manizales to the south, and has access to the national electricity grid which runs near the property.


The Marmato district has been exploited since pre-Colonial times by the Quimbaya people. The Spanish colonists assumed control of the Marmato mines in 1527 and the area has been in almost continuous production ever since. The gold resource of Marmato was so significant that Simon Bolivar, the revolutionary leader who liberated much of South America from Spanish rule, used the mines as collateral with British banks to secure funding for a war of independence against Spain.


The various areas of the Marmato mountain were consolidated in 2009 and 2010 by Medoro: the Zona Alta exploration project, the producing Marmato underground mine in Zona Baja and the Echandia exploration project to the north. The consolidation of the different areas means GCM is in a position to explore, develop and, subject to feasibility and permitting, expand mining operations at Marmato.


On October 4, 2017, the Company announced a change in the focus of the mining style from open pit to underground mining which includes an increase in cut-off grade for the mineral resource estimate and the addition of new material from the deep mineralization below the existing Mineros Nacionales mine. The Company will be filing a NI 43-101 Mineral Resource Estimate to support the most recently announced resource estimate.

Ownership Location
100% Gran Colombia Gold Titiribi mining district of Antioquia 27 km south of Medellin


The Zancudo project in the Titiribí mining district of Antioquia comprises a historical gold mine, the Independencia Mine, in the Middle Cauca Gold Belt that produced about 130,000 ounces of gold with recovered grades of 14.6 g/t Au and 108.4 g/t Ag. The Independencia Mine exploited an epithermal to mesothermal, intermediate sulphidation type vein system that was exploited over 3.5 km with known depths of over 900m. Gran Colombia completed a 14,000m drilling program at Zancudo in 2011 and 2012 that focused on defining new potential resources by following the strike and shallow dip extensions of the Santa Catalina and Manto Antiquo structures that represent the extension to the south of what was mined in the historical Independencia Mine. GCM halted further exploration work on this property following the gold price collapse in 2013 to focus on the modernization project at its Segovia Operations.
In March 2017, GCM announced it had signed an option agreement with IAMGOLD Corp. for the exploration and potential purchase of an interest in the Zancudo Project
