Canadian junior Kenorland Minerals (TSX-V: KLD) has inked an earn-in agreement with Antofagasta (LON: ANTO) that gives the Chilean miner an option to acquire a 70% interest in the Tanacross copper-gold project in Alaska.
Antofagasta could become the project’s majority owner by spending $30 million on exploration over eight years and delivering a preliminary economic assessment on the asset, near the Yukon-Alaska border.
The Santiago-based miner will also make cash payments of $1 million to Kenorland and another $4 million upon exercise of the option.
During the option period, Antofagasta will fund all exploration and Kenorland will be the initial operator, the companies said.
“The property, which covers numerous mineralised systems and target areas, warrants significant exploration to unlock the discovery potential that we believe exists,” Kenorland Minerals chief executive Zach Flood said in the statement.
Once Antofagasta has earned its 70% interest, the companies will form a 70:30 joint venture. If either party’s interest in the JV falls below 10%, its interest will convert into a 2% net smelter returns (NSR) royalty of which a 0.5% NSR can be purchased by the other party for $2 million.
Back to North America
Antofagasta’s move comes as the company reported a drop in production for the second quarter of the year, which forced it to lower its full-year output target to 640,000-660,000 tonnes.
Becoming involved in the Tanacross project marks the company’s come-back to North America. In January, Antofagasta lost its battle on its proposed Twin Metals underground copper-nickel mine and processing facility in Minnesota.
The US Department of the Interior cancelled two mineral leases for Antofagasta’s proposed mine, effectively killing the project and handing a major win to environmentalists.
Kenorland currently holds three projects in Quebec where work is being completed under joint venture and earn-in agreement from third parties.

Drought, operational issues bring Antofagasta guidance down
Antofagasta had disclosed in early June a leak in a pipeline at its flagship Los Pelambres copper mine’s concentrator plant.
It had also said that the operation had been one of the company’s mines hardest hit by the lack of rainfall in the home country.
Copper miners across Chile have been forced in recent years to find alternative means to feed water to their mines as the country’s longest drought in decades and receding aquifers have hampered operations. Many have sharply reduced use of continental freshwater or turned to desalination plants.
The country’s copper agency Cochilco estimates that mining’s use of seawater — either used directly or desalinated — will increase 167% by 2032, while freshwater use will decline 45%. By the end of that period, 68% of water used by the industry will come from the ocean, the agency has said.
Antofagasta noted that throughput at Los Pelambres was 36.2% lower than in the first half of 2021, while grades at its Centinela Concentrates were 35.4% lower.
Second-quarter output fell by 6.5% quarter-on-quarter to 129,800 tonnes. The concentrate pipeline incident at Los Pelambres reduced production by about 23,000 tonnes in the quarter.

Antofagasta had previously said it expected to produce between 660,000 and 690,000 tonnes in 2022.
“Looking to the second half of the year, we expect production to increase quarter-on-quarter as throughput recovers at Los Pelambres with increased water availability, grades improve at Centinela Concentrates and as the copper in concentrates, stockpiled at Los Pelambres’ concentrator plant, is moved to the port,” chief executive Iván Arriagada said.
The company, majority-owned by Chile’s Luksic family, one of the country’s wealthiest, highlighted that from April this year all mining operations have been operating solely using renewable energy. This has “significantly” reduced the company’s Scope 2 emissions, Antofagasta said, without providing further details.
Expansion
Antofagasta is close to finishing a much-needed $2.2 billion expansion of Los Pelambres. The project, which was 82% completed by the end of the second quarter, will add 60,000 tonnes of copper a year over the first 15 years to the company’s overall production.
The plan includes boosting throughput at the plant from 175,000 tonnes of ore a day to an average of 190,000 tonnes a day.
It also contemplates the construction of a desalination plant and water pipeline, which is scheduled to be completed in early 2023.
The facility will benefit the existing operation in cases of prolonged or severe drought, such as the one currently hitting miners and wine makers alike. It could also be used for a potential further expansion, which may follow if Antofagasta can secure the required environmental and regulatory approvals.
