A series of investments resulting in efficiency and improved safety are key factors to place Gran Colombia Gold along the most important gold and silver mining operations in its territory


Gran Colombia Gold is a company with origins in Canada whose main goal is gold and silver prospecting and extraction. Since 2010, the company’s run has allowed its consolidation as a reliable business with stability and responsibility toward its main operations in Colombia.
Gran Colombia Gold’s work in recent years has experienced high production levels. Just in 2018, the company surpassed 200,000 oz. production for the very first time, increasing by 25% the previous year’s accomplishments. In 2019, production reached 240,000 oz. of gold, besides a cash balance of $84 million by December, 2019.
Besides the Colombian operation, the company also has assets and investments in Canada and Guyana,
both in exploration and extraction phases. Gran Colombia Gold is listed in the Toronto Stock Exchange. These and other achievements make Gran Colombia Gold the most important gold and silver extraction company in Colombia.
Angel Meza is the vice-president of mines for Gran Colombia Gold. He graduated as a mining engineer from Central Peru National University (UNCP) in the higher average class. Meza also earned an MBA from Centrum, the business school of the Pontifical Catholic University of Peru (PUCP); and in 2019 finished a master’s in International Leadership from the EADA Business School (School for High Management, Spain).
Meza has developed his mining experience in areas such as

exploration, perforation, explosive demolitions and mining project management. Work has taken him to Retamas, Minas Buenaventura, Barbastro (a subsidiary of Minsur), Los Quenales and Perubar (both of the Glencore group), Minera Aruri and Tamboraque mine, all of these
in Peru; and also to Kamoto Copper Co. and Katanga Mining, both in the Democratic Republic of the Congo, Africa. Meza is also an international speaker and consultant in mining, taking part in these activities in Peru, Chile, Colombia and Ecuador.

Gran Colombia Gold’s main activity is carried out in the Segovia and Remedios municipalities, both in the northwest of the Department of Antioquia, in central Colombia. The company has also grown by acquisition, after purchasing the old
Frontino Gold Mines company from the Colombian government, as well as those in Segovia, Remedios, and also the El Zancudo mine, located in Titiribi (Antioquia) between 2009 and 2010. Gold production from the company averages 17,000 to 20,000 oz. of gold, monthly, delivering a yearly average



of 200,000 and 220,000 oz., and achieving a 220,194 oz. production in 2020.
During 2021, Gran Colombia Gold’s efforts have been destined toward the exploration of three gold deposits: in southern Cali (in the Cauca Valley), Marmato (Department of Caldas) and Segovia (northeastern Antioquia).
One of the latest findings for Gran Colombia Gold is the Sandra K mine, in Segovia. Currently, levels 6 and 7 of the 7-level facility are being










furnished with important investments: an elevator has already been installed, easing the tasks of 506 workers (374 part of the company staff and 132 from outside contractors), avoiding a 935-step staircase after a $1.6 million injection, reducing the run across the stairs to four minutes, delivering a positive impact in time, productivity and -mostly- the workers’ safety.
Other investments have been made at Sandra K to obtain underground machinery and equipment with a $1.5 million budget, resulting in the acquisition of a Sandvik DD210 drill rig, a Sandvik LH307 low profile LHD (load haul dump) and a 15 ton Aramine truck for underground operations. This investment also considered the required training in heavy mining equipment for the staff dispatched at Sandra K.

“Constant improvement is in Gran Colombia Gold’s DNA, as well as
Maintaining its staff’s wellbeing and safety is a top priority for Gran Colombia Gold, after investing in the installation of underground refuge chambers for every operation. Since 2017, more than $1 million has been used for the construction of four refuge chambers in Segovia and Remedios. At the El Silencio mine, a 40-person refuge has been recently deployed as an addition to the three previous refuge chambers in the El Silencio, Providencia and Sandra K mines, each with a capacity to host up to 60 persons for up to 72 hours. And currently, research is being conducted to consider deploying a fifth refuge chamber in the El Silencio mine which would have capacity for 100 persons. It must be noted that underground

refuge chambers in every Gran Colombia Gold mining site are built under high global mining standards, such as those observed by the MSHA (Mine Safety and Health Administration, from the US), besides complying with the Safety Regulations for Underground Mining Labors -part of Decree 1886 from Colombia’s Ministry of Mines and Energy-, and with regulations from the National Mining Agency.

“We highlight the positive impact created by alliances among government agencies, local mayors, communities, NGOs and the private sector,” Meza pointed out.
