How the stated figures have moved

The same figure, as management put it on the earliest and the latest recording we hold. A difference may be a genuine update, a different measure of the same thing (total against indicated), or a mis-heard number — both quotes are here, and both recordings are one click away.

Management view vs outside view

Management interviews are promotional by nature; the outside view is the counterweight. Both are quoted from the recordings, not added by us.

What management spends its time on

Bull · Bear · Watch next

Weighed from the statements on this page — management's pitch and the outside view. Not financial advice, and not our opinion of the company.

▲ Bull case

Management says Arizona deposit of 800+ million tons of mostly oxide copper, with an oxide project delivering $2 billion NPV after tax at a 22.7% IRR, positioned to produce up to 10% of US refined copper.

Read the full case

Management says Arizona deposit of 800+ million tons of mostly oxide copper, with an oxide project delivering $2 billion NPV after tax at a 22.7% IRR, positioned to produce up to 10% of US refined copper. A major commodity investor names it as a core portfolio holding and warrant position.

▼ Bear case

Predecessor Excelsior Mining faced technical problems that forced a 2022 shutdown on this same deposit.

What it rests on
Evidence: 3 moments from 2 interviews
Read the full case

Predecessor Excelsior Mining faced technical problems that forced a 2022 shutdown on this same deposit. Mineral sorting—a $90 million NPV driver—has only been tested on one of multiple rock formations; applicability to others is unproven. Key economics rest on unvalidated assumptions: 68% recovery rate, $460/lb copper, and a novel sulfide leach technology still being developed.

◆ Watch next

Prefeasibility Study due in 18–24 months; permit amendment submission in ~6 months, with 12-month approval process.

Read the full case

Prefeasibility Study due in 18–24 months; permit amendment submission in ~6 months, with 12-month approval process. Q3 2025 commercial production and year-end full production from oxide mine. Satellite project north of main pit (25M tons at 8% copper) construction decision targeted mid-2028.

Each moment links to the exact point in the source recording. The cases are drawn from the transcripts, weighed as written — they are not a rating, a target or a recommendation.

Project 12 statements

The deposit 5

Key takeaway. Management reports that the deposit is mostly oxide copper, with a resource of over 800 million tons at about 0.3% copper overall as of July 2026.

Jurisdiction 2

Key takeaway. Management says the project is located in Arizona and that the permitting path involves amending existing permits, a process they expect to take about 12 months.

Stephen Twyerould· 18 Mar 2026·

Technical risk 5

Key takeaway. Management acknowledges two key technical risks.

Read the full summary

First, they note that predecessor company Excelsior Mining faced technical problems that led to the mine shutting down in 2022. Second, while mineral sorting added $90 million to the NPV, management cautions that this technology was tested on only one rock formation in 2025, and its applicability to other formations is unknown. The company also assumes that sulfide leach technology will work on future sulfide ore projects.

What was actually said
key assumption
sulfide leach technology for future sulfide ore projects
“This is a new technology that could potentially change the game here in the United States. Because for future sulfide ore projects, instead of making a concentrate and shipping that off to Asia, losing control, all those emissions, all those costs, essentially all those bad things, tailings, um tailings dams, nobody wants those.”
Craig Hallworth· 13 Jul 2026·
stated risk
predecessor company Excelsior Mining had technical problems and mine shut down in 2022
“the predecessor company, Excelsior Mining, they'd done an in situ leaching mine on the main deposit. They'd had some technical problems and that mine had to be shut down in 2022.”
Craig Hallworth· 13 Jul 2026·
key assumption
mineral sorting added 90 million to the NPV
“like the the mineral sort of probably added 90 million to the NPV.”

Economics 13 statements

Economics 8

Key takeaway. Management says the project has an after-tax NPV of about $2 billion (at 8% discount) and a 22.7% IRR, using a copper price assumption of $460 per pound.

Read the full summary

The company reports that capex is about $1.5 billion including the acid plant—though a separate claim from July 2026 puts capex at $2 billion. On recent improvements, the company says a satellite project added about $190 million to NPV compared to the prior PEA, the acid plant contributes about $100–$250 million to NPV, and overall NPV has increased by $700 million US after tax in the last 12 months.

How to read this page

What is here

Statements made by company representatives in the interviews listed above — each one carrying the words that made it, the date, and the recording. Nothing is added from any other source: if it was not said on a recording, it is not on this page. The one exception lives in the Claims & Checks record, which cites a metal price from our own feed so a stated cost can be set against it — and labels it as ours wherever it appears.

What is not verified

All of it. Resource figures, economics, timelines and promotional framing are management's own representations, checked against no filing and no technical report. Transcripts are automatic; we repair a clearly mis-heard word but never a number, a date, a unit or a speaker's hedge — “about 8.6 million ounces” keeps its “about”.

How to use it

Treat it as a map of what has been said, not as a source of fact. Where a figure matters to you, open the recording and read the company's filings. Nothing here is financial advice, a recommendation, or an offer to buy or sell any security — these are interested parties discussing their own company.
