Canadian junior Los Andes Copper (TSX-V: LA) is moving forward with plans to build a 110,000 tonne per day operation, which it believes will be Chile’s next major copper mine.
The company’s Vizcachitas project — a copper-molybdenum porphyry deposit 150 km northeast of Santiago — is one of the largest undeveloped deposits not held by a major mining company.
The proposed open-pit mine and concentrator is located at a relatively low elevation of 2,000 metres above sea level, and is just 65 km from a railway in San Felipe, with connections to the Port of Ventanas and two smelters, located 140 km and 90 km from the deposit.
It also sits in the same mineral belt as Antofagasta’s Los Pelambres, Codelco’s Andina and El Teniente, as well as Anglo American’s Los Bronces mines.
“The advantageous size and location of the resources allow the development of the project with a potential lower capital investment in infrastructure than most of the presently considered potential new green-field developments,” Los Andes Copper’s executive chairman, Fernando Porcile, told MINING.COM.
After the recent publication of a preliminary economic assessment (PEA) for the project, released in June, management is preparing a prefeasibility study (PFS) that expects to submit by the end of 2020. If all goes well, the company expects the approval process to take about two years.
Based on the PEA, Vizcachitas would be in operation for 45 years and would require an initial investment of $1.87 billion.
Chile’s President, Sebastián Piñera, recently submitted to Congress a series of modifications to a bill introduced earlier this year.
The proposed law would set stiffer fines and jail time for serious violations of the country’s environmental laws.
It would also make it a crime to mislead environmental inspectors or to obstruct the enforcement of environmental regulations in the world’s top copper producing country.
Referring to those developments, Porcile said that while the proposed modifications could eventually bring additional difficulties to the approval of projects, they reflect the need for companies to increase their commitment to environmental compliance.
“The mining sector in Chile has been heavily regulated for a long time,” Porcile noted. “These changes are being particularly resented by industries that have not been properly supervised in the past and need to adopt more drastic cultural changes.”
The South American nation is highly dependent on mining, and the government is conscious that more projects are needed, said Porcile, who has been in the mining business for more than 50 years.
Copper output in Chile is expected to exceed 6 million tonnes for the first time this year and continue to rise by about 30% over the next 10 years, according to the country’s state copper agency, Cochilco.
Output of the red metal, the agency says, could reach a record of 7.25 million tonnes as early as 2025, thanks mainly to new projects and planned expansions to come online this decade, as Chilean miners confront falling ore grades at older mines.
Production from existing, aging mines, Cochilco notes, will decline by 19% to 4.46 million tonnes annually, but the drop will be offset by new ventures and mine expansions.
The metal’s price has dropped by about 10% since April, and following a trend that many commodities have seen amid global economic instability, demand for the mineral has weakened.
Analysts, however, remain generally bullish about the red metal’s future as China pushes to develop the largest electric vehicle (EV) industry in the world. This effort means Chile’s copper industry, worth $31.5 billion a year, may soon become stage a major comeback.
