Hudbay sets benchmarks to build Copper World/Rosemont mine complex

Toronto-based Hudbay Minerals Inc. has announced benchmarks it must achieve before it proceeds with construction of the Copper World/Rosemont mine complex in the Santa Rita Mountains 35 miles southwest of Tucson.

The requirements include a provision that Hudbay must find a joint venture partner willing to invest an unknown amount in the $2.8 billion project.  Hudbay bought out a previous joint venture partner in 2019.

The benchmarks also include financial targets requiring Hudbay to reduce long-term debt and increase cash reserves. Hudbay’s strategy also limits debt earmarked to the project to $500 million.

In addition, Hudbay states it must renegotiate a metal streaming agreement where it receives $230 million for mine construction in exchange for long term sales of gold and silver at fixed prices.

Copper World’s high production of sulfuric acid poses serious pollution and water depletion threat to Santa Cruz River Valley

Hudbay Minerals’ radically revised plan to mine copper from the Santa Rita Mountains 35 miles south of Tucson increases water use and threatens to further contaminate the Santa Cruz River basin by relying on a rarely used copper ore processing technology that will generate millions of tons of sulfuric acid, according to information released by the company and previous environmental studies.

Toronto-based Hudbay published a Preliminary Economic Assessment (PEA) for the Copper World Mining Complex in a June 8 press release. The PEA provides a general description of a $2.8 billion mining plan that straddles both sides of the Santa Rita Mountain range.

Hudbay’s previous plan to construct the Rosemont mine on the east side of the range was projected to cost $1.9 billion. The company said it would release a technical report providing more details as an addendum to the PEA within 45 days.

According to the PEA, Hudbay intends to blast three, relatively shallow, open-pit mines on the west flank of the Santa Ritas in the initial years of a 44-year project – more than twice as long as the former plan to develop only the Rosemont mine. Hudbay says it will begin processing copper ore from the much larger Rosemont pit, now called the East pit, starting in the third year.

Sulfide ore from primarily the East/Rosemont pit will be used partly to generate millions of tons of sulfuric acid on-site. The acid will be applied to crushed copper oxide ore found primarily on the mountain’s west side to extract a copper-laden solution. Millions of tons of unused sulfuric acid will be offered for sale.

Hudbay says it is developing plans to build at least three open-pit copper mines on west side of Santa Rita Mountains

Four years after stating there were substantial copper resources adjacent to the proposed Rosemont Mine on the northeast flank of the Santa Rita Mountains, Toronto-based Hudbay Minerals, Inc. is now saying it plans to develop at least three open-pit mines on the ridgeline and down the west side of the range overlooking Sahuarita and Green Valley.

The company has outlined a sprawling mining development that would destroy a section of the Santa Rita’s ridgeline and possibly connect the west side mining operations called Copper World with the proposed Rosemont Mine on the northeast flank of the mountain.

Hudbay’s preliminary plans are outlined in a mine reclamation plan submitted to the state and in a recent press release and investors’ report. Hudbay has not completed a formal economic analysis of the project nor a feasibility study required under Canadian mining laws before mining can begin. Hudbay states it expects to complete the reports next year, followed by two years of permitting, three years of construction with mining starting in 2027. Continue reading

Hudbay tells investors and analysts that it owns enough land to mine the western side of the Santa Rita Mountains

Toronto-based Hudbay Minerals executives said Tuesday there is sufficient space on its private 1,250-acre Copper World site on the west side of the Santa Rita Mountains to construct open-pit mines and processing facilities to handle recent discoveries of high-grade sulfide and oxide copper ore.

Screen Shot 2021-08-11“We have adequate land on which to deposit tailings as well as on which to deposit waste rock,” Hudbay CEO Peter Kukielski told stock analysts during the company’s Aug. 9 conference call to discuss 2nd Quarter financial results.

Kukielski said the Copper World project could proceed separately from the $1.9 billion Rosemont Mine on the northeast side of the Santa Rita Mountains, which was stopped after a 2019 federal court ruling that is now on appeal.

“Rosemont remains a priority for us,” Kukielski said, “but Copper World presents a super exciting potential alternative or addition.” Continue reading

Rosemont will destroy Santa Rita Mountains to export copper overseas

Arizona’s unrefined copper concentrate exports are soaring at the same time two foreign-owned, multinational mining companies are planning to construct the Rosemont and Resolution copper mines. The mines would be among the largest in the country, raising questions of whether most, if not all, of the copper would be exported.

Arizona has long been the nation’s leading copper-producing state. And for decades most of the copper concentrate extracted from sulfide ore bodies such as those found at the proposed Rosemont and Resolution mines was processed at giant furnaces called smelters. The smelters transformed copper concentrate into metal that could be further refined into products such as wire and tubing.

The smelters also were notorious for emitting high levels of air pollution and heavy metals including arsenic and lead. One by one, the smelters closed leaving the state today with only two located in the communities of Hayden and Miami.

At the same time, foreign investment in Arizona copper mines sharply increased with Grupo Mexico taking control of three Arizona mines through its Asarco subsidiary and the Japanese conglomerate Sumitomo Corp. purchasing a 28 percent share in Phoenix-based Freeport McMoRan’s Morenci mine, the largest copper mine in the United States.
