Taseko Mines Limited — renamed Trekor Metals Limited in June 2026, ticker unchanged (TGB on NYSE American, TKO on TSX/LSE) — is a Vancouver-headquartered copper producer incorporated in British Columbia. It is, at its core, a two-asset copper company with a development-stage tail:
Revenue model: sell copper (concentrate from Gibraltar; cathode from Florence) and molybdenum at prevailing market prices — a pure price-taker, no take-or-pay pricing power, margin = (metal price − unit cost). The only contractual structure of note is Florence's 81% cathode offtake to Mitsui during initial years. Development tail: Yellowhead (large BC copper, in environmental assessment, now a BC "priority major project") and Aley (niobium, converter pilot ongoing) — real optionality, but both years and heavy capex away. New Prosperity is effectively retired as a Taseko-operated asset (see Lens 10).

segments.csv empty — figures ``, FY2025 basis:
| Segment | FY2025 | Note |
|---|---|---|
| Gibraltar copper | 98.1M lbs produced, 0.22% grade | ~90%+ of revenue; the only material producer in FY2025 |
| Gibraltar molybdenum | 1.9M lbs | Byproduct credit; moly prices volatile |
| Gibraltar silver | streamed 100% to Osisko | No revenue upside to Taseko |
| Florence cathode | ~0 (FY2025); 1.5M lbs Q1'26 | Pre-commercial in FY2025; the FY2026+ growth segment |
| Total revenue | C$673M (record) | Up on higher realized copper (Q4 realized US$5.13/lb) |
Geography: revenue ~entirely Canada-sourced (Gibraltar) in FY2025; the segment story of 2026-2028 is the mix shift to US-sourced Florence cathode — from ~0% to a targeted 85M lbs/yr, which at nameplate would be a similar copper volume to Gibraltar but at less than half the unit cost. The trend that matters: Gibraltar decelerating/volatile (2025 output missed 120-130M lb guidance — see Lens 5), Florence accelerating from zero. The whole equity is a bet on that crossover.
FY2025 (audited, C$ unless noted):
Q1 2026: revenue C$237.1M (+70% YoY), net income C$16.8M (vs a loss a year earlier), EPS C$0.046. Florence produced 1.5M lbs cathode (harvest began end-Feb). Cash C$169M, total liquidity C$322M at Mar 31 2026. Management flagged declining Gibraltar capitalized stripping + winding-down Florence capex → improving FCF and a deleveraging plan. Note: Florence's wellfield acidification only starts in fall 2026, so the ramp is back-half-weighted — 2026 guidance 30-35M lbs cathode.
Balance-sheet flags: US$500M senior secured notes at 8.25%, due May 1 2030 (issued Apr 2024, refinanced the 2026 notes). Total debt ~C$793M, senior notes ~C$706M long-term; net debt ~C$620M. Leverage is meaningful for a company this size — net debt / FY2025 adj EBITDA ≈ 2.7x, and the coupon is a real fixed cash drag until Florence's cash flow deleverages it.
Market reaction / what's priced: stock is up ~18% YTD and has re-rated hard on Florence de-risking + copper's record run. The market is already rewarding the ramp.

Copper mid-cap peer set (same critical-materials/copper bucket).
| Company | Ticker | Mkt cap | EV/EBITDA | 2025 Cu output | Note |
|---|---|---|---|---|---|
| Taseko / Trekor | TGB / TKO | ~US$2.41B | ~17x trailing / ~8-9x fwd | ~98M lbs (~44kt) | Highest growth %, highest copper beta |
| Hudbay Minerals | HBM | ~US$9.3B | n/a | larger, diversified | 0.2% div yield; Q1 adj EBITDA US$421.9M |
| Capstone Copper | CS.TO | n/a | ~4-5x | 224,764 t | P/NAV 0.85-0.90x; net debt US$738M |
| Lundin Mining | LUN.TO | n/a | n/a | ~322,000 t | P/NAV ~0.95x |
| First Quantum | FM.TO | n/a | n/a | ~396,000 t | Steepest P/NAV discount; country risk |
| Ero Copper | ERO | n/a | n/a | smaller | Q1 adj EBITDA US$125.2M |
Read: Taseko is the smallest and highest-beta of the mid-caps and screens expensive on trailing EV/EBITDA (~17x — FY2025 adj EBITDA US$168M vs EV ~US$2.86B ) precisely because FY2025 was a depressed base (bad grade, Florence pre-revenue). On forward EBITDA (Florence ramping + Gibraltar normalizing + high copper), the multiple compresses toward ~8-9x and, at Florence nameplate + $5 copper, toward ~5-6x. The valuation only works if you underwrite the ramp — you are not buying a cheap trailing multiple, you are buying growth delivery. Peers like Capstone at 4-5x are cheaper on today's numbers with less execution left to prove.
The tape says this is a copper-price-torque stock with binary project catalysts layered on:
Pattern: the dominant driver is the copper price (high-cost Gibraltar gives outsized torque), with Florence milestones and permits/tariff headlines as the idiosyncratic movers. It does not trade on Gibraltar volumes except when they miss badly. Forward catalysts: the June 30 2026 Commerce Dept refined-copper-tariff review (decides the 15%-in-2027 duty), fall-2026 wellfield acidification, Q2/Q3 2026 ramp prints, and copper/COMEX.

Regulatory findings:
Built bottom-up from FY2025 actuals + 2026 guidance; all outputs ``, arithmetic shown; no forecast.ts logged (watchlist rule). Reported in C$/share on ~365M shares. Drivers: copper price, Gibraltar volume/C1, Florence ramp (30-35M→~85M lbs), ~US$41M notes interest, D&A, FX.
FY2026 (Florence partial ramp, back-half-weighted):
FY2027 (the inflection year — Florence full-year, approaching nameplate):
FY2028 (Florence at/near 85M lbs nameplate full year):
The dispersion is enormous by design — this is a leveraged, high-cost copper producer with a growth ramp and USD-debt FX overlay. Small copper-price and Florence-ramp moves swing EPS multiples. Suggested (unlogged) Brier forecast: "TGB FY2027 adjusted EPS ≥ C$0.60, p≈0.55, resolves 2028-03-31."
Bull case. Copper is entering a structural, multi-year deficit — surplus 2025 → deficit 2026, acute 2027-2028; AI data centres alone 250-550kt/yr by 2030; IEA demand 27→37Mt to 2050. Into that, Taseko delivers Florence: US-domestic, lowest-quartile (US$1.11 C1), low-carbon LME Grade A cathode ramping 0→85M lbs, into a US market structurally short refined copper with a pending 15% (2027)/30% (2028) import tariff that would hand domestic cathode a durable price premium. Gibraltar (100%-owned, to 2044) is a fully-consolidated, high-torque copper option on top. Deleveraging as Florence cash flows in → equity value transfers from bondholders to shareholders. Analyst targets C$14 (Canaccord) / US$9 (Cantor) / ~C$12.79 consensus imply ~25-40% upside.
Bear case (permanent-impairment lens). (1) Gibraltar is a high-cost, low-grade, guidance-missing asset — a sustained copper move to ~US$3.50 compresses its margin toward zero and the equity is mostly Florence + hope. (2) Florence ISCR carries irreducible hydrogeologic risk — the entire licence rests on demonstrated groundwater containment; any excursion, permit challenge, or slower-than-modeled recovery re-opens the existential question that dogged it for a decade. (3) The balance sheet is levered with 8.25% money — US$41M/yr cash interest is fine at $5 copper and a ramping Florence, punishing at $4 copper and a stalled ramp. Pre-mortem (18 months out, thesis broke): copper mean-reverted to ~US$4, Florence's fall-2026 acidification underdelivered leaving 2027 output at ~45M lbs not 65M, Gibraltar missed again on grade — adj EBITDA halved, the ~17x trailing multiple that "priced the ramp" de-rated to a peer 5-6x, and the stock halved. Contrarian view the market is refusing to see: the tariff "protection" for Florence is weaker and later than the headline — cathode is currently EXEMPT from the 50% Section 232 tariff (only semis/derivatives are hit); the refined-copper duty is merely proposed, contingent on a June-30-2026 Commerce review, and doesn't start until Jan 2027. The durable domestic premium is a 2027 option, not a 2026 fact — and the stock is being priced as if it's already banked.
Dismantling the bull: Revenue is ~90% one aging, high-cost pit (Gibraltar) that just missed guidance by 20% — concentration + execution risk in one sentence. The moat everyone cites (Florence's cost/carbon) is real but unproven at scale — one quarter of 1.5M lbs against an 85M-lb nameplate proves the plant runs, not that the wellfield delivers modeled recoveries over 22 years; ISCR at commercial scale in the US is nearly untested (Florence is basically the commercial reference case). The most dangerous thing bulls underestimate is hydrology, not competition — a single injection-containment problem is a headline-and-permit event, and Arizona groundwater politics are not friendly. Capital allocation: management chose 8.25% secured debt over equity to build Florence — smart if it works, a solvency-tightener if copper and the ramp both disappoint; and they streamed away 100% of silver and 2.67% of Florence copper for modest cash. What must hold for today's ~US$2.4B cap: ~$5 copper and a clean Florence ramp to ~65M+ lbs by 2027 and Gibraltar normalizing. If growth disappoints 20-30% (Florence 2027 at ~45M lbs, copper at $4.25), adj EBITDA is ~C$300M not ~C$500M and the stock is a ~5-6x-EBITDA copper miner worth materially less than US$2.4B. Single permanent-impairment scenario: an EPA/ADEQ groundwater excursion at Florence forcing a suspension — low probability, catastrophic payoff, and it is the whole reason the asset was contested for a decade.

Operationally the best growth story in large-cap mining — ~10%/yr copper+gold volume compounding, ~25% ROE, 60% mineral gross margins — priced two-to-three turns below Western copper peers on a discount that is structural, not temporary (UFLPA listing, China-SOE governance, hardest-jurisdiction asset base). Bullish the metal, skeptical of the re-rating.
Right company, real super-cycle, wrong entry — a world-class tungsten crown jewel buried inside a low-margin battery-materials SOE, already +222% in 52 weeks at ~20x forward earnings on peak tungsten prices; own the thesis, watch the vehicle.
Best-in-class precious-metals streamer — ~78% cash margins, fortress balance sheet, ~50% production growth to 2030 and the largest streaming deal ever (BHP Antamina, $4.3B) locked in — but priced as such (sector-high ~1.97x P/NAV, ~27x earnings). At ~$111 it is a de-risked, leveraged long-gold/silver bet with acute Salobo concentration, not a value entry. Direction hinges on the metal price and the Antamina ramp, not the model.
