(Kitco News) - A junior buys into a junior, a trading house commits to a decade of output, and a billion-tonne copper deposit gets its first real balance sheet
A Canadian junior miner with a processing plant under construction in Colombia has agreed to spend C$28.8 million buying a piece of one of the largest undeveloped copper deposits in the Americas.
Denarius Metals will take 15.6% of Copper Giant Resources, anchoring a C$31 million private placement announced Thursday, Copper Giant said. On the same day, Copper Giant granted the commodities trading house Trafigura long-term offtake rights over a fifth of the future output from its Mocoa copper-molybdenum project in Putumayo, in southern Colombia.
Frank Giustra, already the company's principal shareholder at about 13.5%, is adding to that position and will hold roughly 15.8% on a partially diluted basis once the deal closes. Ian Harris, Copper Giant's president and chief executive, is also subscribing. All three have agreed to two-year lock-ups.
Giustra told Kitco News by email Thursday morning that the appeal was both the partner and the politics.
"Great long-term partner," he said. "And with the new pro-mining President who considers this project vital to Colombia's interest, we can advance the Mocoa deposit very quickly."
The reference to timing is not incidental. Colombia swears in President Abelardo De La Espriella on Friday, replacing an administration that had banned new hydrocarbon exploration contracts and clashed with multinational coal producers. Copper Giant's investor presentation quotes the president-elect saying it is "time to restore investor confidence" and that Colombia "must return to exploring and developing our strategic resources such as copper, silver, and gold."
Juan Camilo Nariño, head of the Colombian Mining Association, has said between $3.6 billion and $4 billion of mining investment could materialise over the next four years across five gold, copper, coal and nickel projects that have completed exploration or obtained licenses but never moved into construction.
Investors liked it. Copper Giant traded as high as C$0.97 on the TSX Venture Exchange after the release crossed at 11:18 a.m. ET, about 15% above Wednesday's close of C$0.84, on more than 3 million shares. It held above the prior close through the afternoon. The stock has risen roughly sixfold over 12 months, from a low of 14.5 Canadian cents, and is trading near its 52-week high of C$1.
The deposit
Mocoa is large and it starts at surface.
Copper Giant reports 1.12 billion tonnes of inferred resources grading 0.51% copper equivalent, or 0.31% copper and 0.039% molybdenum, containing roughly 7.6 billion pounds of copper and about 450,000 tonnes of moly. The estimate was completed by APEX Geoscience with an effective date of Nov. 18, 2025, and the technical report was filed in January.
Inside that footprint, the company identifies about 190 million tonnes grading 0.94% copper equivalent as a potential starter zone, with mineralization from surface and what it describes as clean metallurgy. That is the part a preliminary economic assessment can build a case around, and it is why a trading house can commit to volumes years before a mine exists.
One note on the arithmetic that works in the company's favour. The copper equivalent grade is calculated using $4.00 a pound copper. Copper is currently trading well above that, which makes the disclosed figure conservative on the copper side.
What Trafigura gets
The offtake agreement, dated Aug. 5, gives Trafigura the right and the obligation to purchase 20% of the copper concentrate and 20% of the molybdenum concentrate produced at Mocoa. It runs for 10 years from the start of commercial production, on arm's-length market terms. If minimum volumes are not delivered over the period, Trafigura may elect to extend.
That last clause is the tell. This is a firm commitment on both sides rather than an option, and it hands a company that has not yet made a construction decision something most developers never get: a guaranteed route to market.
The molybdenum matters more than it might appear. Beyond hardening steel alloys, moly sits on China's export control list alongside tungsten, tellurium, bismuth and indium, which puts a Western-hemisphere source in the critical minerals conversation rather than the byproduct column.
"Colombia has the geological conditions and the opportunity to become an important copper producer," said Edmundo Vidal, Trafigura's director for Latin America, citing "the country's recognition of copper as a strategic mineral."
Trafigura is employee-owned, operates in more than 150 countries, and already has a financing relationship with Denarius through a prepayment facility on the Zancudo project.
Why anyone is writing cheques for copper right now
The deal lands in a week that has been unusually loud for copper supply.
Copper for September delivery touched $6.7045 a pound on the Comex this week, an all-time high in the United States. The metal is up roughly 17% in New York this year and more than 50% over 12 months. In London, it reached $14,369.50 a tonne Thursday, the highest since January, after the Democratic Republic of Congo banned exports of copper and cobalt concentrate, effective immediately, according to a government order reviewed by Reuters.
Two other supply stories broke in the same stretch. Codelco paused expansion work in the Andes Norte section of El Teniente, the world's largest underground copper mine, saying six months of study had identified seismic risk different from anything it had previously monitored.
And the chemistry is tightening. Disruption in the Gulf has knocked out around half of seaborne sulphur shipments and China has halted its own sulphuric acid exports until December, together removing close to a quarter of global acid supply. A study published this week by GEM Mining Consulting estimates more than 15% of the world's copper production, about 3.6 million tonnes a year, depends on acid-leach processing.
There is also a shift in who buys mining assets at all. Zijin Gold walked away from a $3.9 billion takeover of Canada's Allied Gold this week after Chinese regulators declined to sign off, taking a 9% stake instead. Bloomberg reported the decision reflects Beijing pulling back from large mining acquisitions after two decades as the sector's most acquisitive buyer.
Against that backdrop, a junior taking a strategic position and a trader locking up concentrate looks less like an outlier and more like the model.
The people, and the permit
Colombia's obstacle has never been geology. It has been getting anything approved.
Harris advanced Mirador, the first large-scale mine in Ecuador, to construction at Corriente Resources, which sold for $690 million. Director Mark Gibson is a former chief operating officer of Ivanhoe Electric and Cordoba Minerals. Thyana Alvarez, vice-president and country manager, is credited by the company with securing Colombia's first new mining permit in 20 years, and was named by Semana among the country's most influential women in 2024 and 2025.
The groundwork shows. The company says updated cadastral records confirm no overlap between the regional forest reserve and the known Mocoa resource, and that it secured a unified concession in June covering long-term development. Mocoa sits roughly 426 kilometres from the Pacific port of Tumaco and 531 kilometres from Buenaventura, and the company reports an 85% local workforce and an operating water plan based on rainwater harvesting rather than drawing on nearby sources.
The board seat
Copper Giant will appoint Carlos Augusto Suárez Rojas to its board effective on closing, subject to TSX Venture Exchange approval.
Suárez is a Colombian attorney and political strategist and the founder and chief executive of Estrategia & Poder, a Bogota public affairs consultancy. According to Copper Giant, the firm designed and executed the campaign strategy for De La Espriella's presidential run and advises several state governments in Colombia.
Federico Restrepo-Solano, Denarius's chief executive, joins Copper Giant's advisory board.
Terms
The placement is priced at C$0.72 a share for 43,055,550 shares, a 14% discount to Wednesday's close and roughly a quarter below Thursday's high. Shares carry a four-month-and-one-day hold period, and no finder's fees are payable.
The two-year lock-ups are the offset. Denarius, Giustra and Harris are buying at a discount into a stock that rose on the news, and none of them can sell into that move for 24 months.
On closing, Copper Giant will have 256,429,248 shares outstanding, alongside 88.6 million warrants and 18.1 million options. Denarius becomes a new insider under Canadian securities law.
Because Harris is an insider and Giustra a significant shareholder, their participation is a related-party transaction under Multilateral Instrument 61-101. The company expects it to be exempt from the formal valuation and minority approval requirements, on the basis that the insider portion will not exceed 25% of market capitalization.
Denarius is making the investment while completing a 1,000 tonne-per-day plant at Zancudo, in Colombia's Cauca Belt, expected to produce high-grade gold-silver concentrates in the fourth quarter.
Proceeds will fund exploration and project development at Mocoa, including district-scale exploration, beyond a preliminary economic assessment now underway and toward a construction decision. The financing is expected to close on or about Aug. 21, subject to TSX Venture Exchange approval. The Trafigura offtake is conditional on it completing.
