Barrick and Rio Tinto Rushed Into One Idaho Copper District. Zeus Owns the Ground Next Door.

October 31, 2026

In 2023, a company called Hercules Metals (TSXV: BIG) drilled into a blind copper porphyry system in western Idaho and named it Leviathan.1 What happened next tells you how the market reads a discovery of that kind. Barrick, one of the largest gold and copper miners on earth, made a strategic equity investment of roughly C$23.4 million into Hercules.2 Rio Tinto, Scout, NevGold, and other names staked ground around it. More than 60 kilometers of claims went down in what the area now calls a staking rush.3

Directly beside that discovery sits a property that was staked before Leviathan was found. It belongs to Zeus North America Mining Corp. (CSE: ZEUS | OTCQB: ZUUZF | FSE: O92), and it is the company’s flagship. It is called Cuddy Mountain.4

That is the whole setup. The majors are in the district. Zeus is in the district too, on the parcel next door, and it trades for a fraction of the neighbor that drew them in.

The discovery that rewired a quiet corner of Idaho

For most of a century, this part of Idaho was known, if at all, for historic high-grade silver workings. Then Hercules ran modern, systematic exploration and located the Leviathan porphyry in the volcanic rocks underlying the area.1

The drill results that defined Leviathan belong to Hercules, and it is worth being precise about that. Hercules reported intervals such as 185 meters grading 0.84% copper with silver and molybdenum, including a higher-grade core, and a separate interval of 420 meters grading 0.60% copper.1 Those are Hercules’ holes on Hercules’ ground. They are the reason Barrick wrote a check and the reason the majors moved in. They are not Zeus’s results, and nothing about them guarantees what lies beneath the property next door.

What they do establish is that a genuine porphyry copper system exists in this district, confirmed by the drill, backed by a major. That is the backdrop against which Zeus’s position has to be read.
