Alaska has drawn prospectors for well over a century, from the gold rushes of the Klondike and Nome to the large mines that operate there today. Its geology is unusually generous: the same forces that built Alaska’s mountains also concentrated gold and copper deep underground. Many of the state’s most valuable deposits are what geologists call porphyry systems, large bodies of rock where gold and copper are spread through huge volumes at relatively low grades. These are not the narrow, high grade veins of mining lore. They are broad targets that can support decades of production when the economics work, which is why companies keep returning despite the distance and cold.
What makes copper interesting right now is demand. Electric vehicles, power grids, and the rapid buildout of data centers all lean on it, and prices have climbed to levels rarely seen before. Copper recently traded around $6.15 to $6.20 per pound, close to record highs and far above its level of a few years ago. The catch in Alaska is infrastructure. Many deposits sit far from roads, power, and ports, so a promising find can take years and heavy investment to become a mine. That tension, rich geology on one side and remoteness on the other, shapes almost every project in the state, including the one that opened a new drilling season this week.
That project belongs to U.S. GoldMining Inc. (NASDAQ: USGO), a small exploration company that owns 100% of the Whistler Gold-Copper Project, about 105 miles northwest of Anchorage. The company today announced that it had started drilling for the year, putting its first rig to work on a group of high priority targets called the Whistler Orbit while a second rig headed to the site. First assay results, the laboratory measurements that tell explorers how much gold and copper the rock actually holds, are expected by the end of the third quarter.
For a company at this stage, drilling is the main event. Explorers live and die by what comes out of the ground, and fresh results can quickly change how the market values a project. The Whistler Orbit is what geologists call a porphyry cluster, an area of roughly 7.5 kilometers by 4.5 kilometers where the technical team has mapped more than 25 separate targets using geology, geophysics, and soil chemistry. Because porphyry deposits tend to form in groups, testing close to an existing one raises the odds of finding another.
The drilling builds on a study the company released earlier in 2026 called a preliminary economic assessment, or PEA, an early look at whether a deposit could make money. Using cautious assumptions and only part of the known resource, that study estimated an after-tax net present value of $2.0 billion, an internal rate of return of 33%, and a payback period of about 2.1 years. At the higher metal prices seen in the market today, the same study pointed to a net present value nearer $4.9 billion. Those numbers carry the usual caveats of early work, but they show the scale of the prize.
Copper prices add another layer. The base study assumed a copper price well below where the metal trades now, so every move higher lifts the theoretical economics on its own. Infrastructure may be shifting too. A neighboring company, Terra Energy Center, recently received $89 million in federal funding from the U.S. Department of Energy to study a large power plant about 30 miles from Whistler, and the state has proposed a new access road through the area. Neither is owned by U.S. GoldMining, yet both would ease the remoteness that has long held such projects back.
None of this guarantees a mine. Exploration is a long and uncertain business, and most targets never turn into one. What this week marks is the start of a fresh test, with real drill core coming out of the ground and answers due within months. The wider story is straightforward: an early stage company is putting its central idea to the test in a place where the geology is generous and the logistics are hard, while the metals it is chasing are worth more than they have been in years.
