McEwen’s Los Azules copper project gets key environmental approval
The company anticipates construction to begin as early as 2026.
Quebec-focused NuVau Minerals aims to go public this month, a move it says will help it access provincial government support for exploration and development of its past-producing Bracemac McLeod copper-zinc project in the Matagami camp.
The company already has a three-year, C$30 million earn-in agreement with Glencore (LSE: GLEN), and a preliminary economic assessment (PEA) for the project, where mining goes back more than 60 years. Glencore was among a handful of miners in the region, and from 2013 until 2022 operated Bracemac McLeod.
Peter van Alphen, NuVau president and CEO, says listing on the TSX Venture Exchange will help NuVau tap some of the billions of dollars in the province’s funding agencies aimed at mining.
“Quebec is…I would say one of the best if not the best jurisdiction to be in mining,” van Alphen told The Northern Miner in an interview. “(Government funds) will work with you to finance development. But some of them won’t do it for a private company. We’re not primarily an exploration company, we’re a mining company looking to do exploration.”
NuVau is approaching the end of its deal with Glencore to explore and gain full interest in the Matagami camp, located in the province’s west, about 800 km north of Montreal.
The agreement, which ends next March, includes the option to acquire the infrastructure at Matagami, comprising the Bracemac McLeod mine and its mill
NuVau’s 2023 PEA, which focused on the Caber Complex deposits west of Bracemac McLeod, outlined a project of almost 10 years with a net present value (at 8% discount) of C$115.9 million. Initial capital costs were pegged at C$172.3 million, with a 20% internal rate of return.
Quebec is well-known for its institutional funds that back mineral activity, such as Investissement Québec, the provincial pension fund Caisse de dépôt et placement du Québec, and Diversification of Exploration Investment Partnership (Sidex). Tapping into that ecosystem will help NuVau advance its project faster, van Alphen said.
“We saw them coming as an investor, (and) the credibility that these groups would add to us is of great value to us,” the CEO said. “So we decided to take the company public to bring these groups in.”
While van Alphen says NuVau could use the existing mill at Bracemac McLeod, it needs to build a tailings facility before it’s ready for production, as well as raise C$50 million.
“We’re lucky with our access to infrastructure that we can take advantage of,” he said. “(The mill) has 3,000-tonne-per-day capacity, there’s a rail siding there, and we can ship concentrate there by rail. I don’t like the term, but it’s a hub and spoke. We can own the hub.”
If the listing is successful, the company’s milestones for next year are an updated PEA and submission of permits to the Quebec government. In 2026 it aims to complete a feasibility study, with production starting the same year or in 2027.
“We believe we will be able to take advantage of revenue from production from the existing resource to fund part or possibly all of this exploration going forward,” he said.
Van Alphen stresses that the real prize for NuVau is exploring its vast land package along the Abitibi Greenstone belt. Roughly bordered to the east by the Bracemac McLeod mine, the property runs 85 km to the west, and 30 km from north to south. Maple Gold’s (TSXV: MGM) Joutel mine sits just south of the property.
“It’s very large… and less than 5% of it has had significant exploration,” he said. “It has potential to be a major producer in base metals and precious metals as well.”
Exploration in the Matagami area dates back to 1957, when six companies including Leith Gold Mines, Dome Mines and Iso Uranium Mines merged to form the Mattagami Syndicate. A year later, an agreement between that syndicate, Canadian Exploration and Noranda and McIntyre Mines was made to create Mattagami Lake Mines. Production by various companies, including Glencore, ran from 1963 until 2022, during which almost 60 million tonnes of copper and zinc were produced from 12 mines.
The Caber deposit, part of Caber Complex, hosts 2.6 million measured and indicated tonnes grading 6.11% zinc, 1.15% copper, 10 grams silver per tonne and 0.21 gram gold for 91,200 tonnes zinc, 17,100 tonnes copper, 481,000 oz. silver and 9,990 oz. gold. Inferred resources total 109,000 tonnes at 4.96% zinc, 1.01% copper, 8.12 grams silver and 0.19 gram gold.
Caber Nord, also in the Caber Complex hosts 1.1 million indicated tonnes at 4.96% zinc, 1.23% copper, 18.1 grams silver and 0.13 gram gold for 54,900 tonnes zinc, 13,600 tonnes copper, 645,000 oz. silver and 4,700 oz. gold. Inferred tonnes come to 5.7 million grading 1.96% zinc, 1.34% copper, 10.3 grams silver and 0.11 gram gold for 112,300 tonnes zinc, 76,700 tonnes copper, 1.8 million oz. silver and 19,800 oz. gold.
Remaining resources under Bracemac McLeod, such as the McLeod Deep and Extension could yield another three or four years of production, according to the PEA. Another target, the Renaissance discovery, a volcanogenic massive sulphide deposit northeast of Caber North, could hold a mine life of more than 20 years. The company plans to start a 10,000-metre drill program at Renaissance this winter.
