Three thousand, nine hundred and ninety-six. That's how many new federal lode claims were staked across the American West in April 2026, according to Stake & Paper's Staking Report data — enough new ground, after 236 closures, to push the total number of active claims on U.S. public land past 579,000.
The number matters because it tells a story the price charts can't. Copper miners' ETF is up sharply over the past year, gold sits near record territory, and the easy read is that everyone already knows where the money's going. But claim staking is a leading indicator — miners plant flags on ground months or years before a shovel goes in. April's filings show the flags are still going up in two very different places: a quiet county in eastern Oregon, and the copper heartland of southeastern Arizona.
Oregon's surprise leader
The month's single biggest staker wasn't a major. It was Scout Discoveries Corp, a small exploration company that filed 607 new claims covering more than 12,000 acres, almost entirely in Baker County, Oregon, per ClaimWatch data — good for the largest share of any single company's activity that month. Scout has built its business on staking ground first and partnering later: it struck a US$30M earn-in agreement with Centerra Gold for the Lehman Butte Au-Ag project in Idaho, and separately reported high-grade results from the Speed Goat Porphyry Au-Cu-Ag Project, Nevada. The Baker County filings extend that same playbook — stake a district, prove it up, then let a larger partner write the check.
Arizona's copper corridor
Second on the list was a name investors know for very different reasons: Anglo American. The company filed 509 new claims across roughly 10,300 acres, concentrated in Graham and Greenlee counties, Arizona, according to ClaimWatch data. Greenlee County is not obscure ground — it's home to the Morenci Mine, which Wikipedia and Freeport-McMoRan's own materials describe as the largest copper mining operation in North America, owned by Freeport-McMoRan. Anglo isn't a stranger to the district either. Nearly a decade ago the company took over the nearby Copper Springs porphyry project in the adjacent Globe-Miami district, where Anglo American manage[d] and operate[d] the Project after optioning it from Eurasian Minerals. New claims this close to Freeport's flagship pit suggest Anglo is doing generative exploration in a district it already knows, even as the company works through the biggest transaction in its history: its merger with Teck Resources, which CEO Duncan Wanblad said in July remains on track... with the expected completion window of September 2026 to March 2027 unchanged.
That a company mid-merger is still filing new claims in Arizona is itself a data point. Exploration budgets rarely survive a corporate reorganization intact; here, they clearly have.
The churn underneath
Staking new ground and walking away from old ground happen simultaneously, and April's data shows both. La Paz County, Arizona, logged 37 claim closures — the most of any county tracked that month, per ClaimWatch data — while Freeport-McMoRan itself closed 25 claims in Grant County, New Mexico, even as it opened 112 new ones nearby, ClaimWatch data shows. That's not contraction. It's portfolio management: miners drop the ground that didn't pan out and replace it with ground that might.
A rotation within energy
The staking data lines up with what the market is pricing. Copper miners have run hard — the sector's ETF has gained a striking amount over the past year, according to market data, and closed Wednesday's session with copper miners' ETF (COPX) at $89.90, up +0.74% on the day. The broader energy sector ETF (XLE) closed at $65.10, up +0.51%, with its 14-day RSI reading deep in overbought territory per market data — a sign traders have already priced in a lot of good news. Gold traded at $4,385.39 an ounce, up +1.41%, and silver at $65.34, up +1.91%, both near record levels that make even marginal exploration ground worth staking. Oil, by contrast, sat still: WTI crude futures settled at $90.63/bbl a barrel, down -0.06%, and Brent at $95.23/bbl, essentially flat. Capital inside the energy complex is voting with claim stakes, not drilling permits, and this month it voted for copper and gold.
None of this proves a boom. It proves that the exploration cycle behind the copper and gold rally hasn't stalled — it's just moved to Baker County and Graham County, where nobody's watching yet.
