Osisko Metals Reports Deepening Losses. Two Tier-One Miners Just Bought at a Quarter of the Current Price.

In an ironic move, Osisko Metals (TSX: OM) stock jumped 20.8% after reporting a C$84 million quarterly loss that brought its first-half 2026 burn to C$159 million. The market's reaction to deepening losses was to bid the stock higher. That doesn't happen by accident — and it's not because Wall Street fell in love with the burn rate.

The narrative around Osisko is straightforward: a cash-burning explorer with no revenue, a P/B ratio of 12.8x (versus 2.8x for the Canadian metals and mining industry average), and widening losses. On a spreadsheet, it looks expensive.

The key to the story is that two of the largest mining operators in the world have been buying at prices the market has already left behind.

The variable the market is focusing on: losses. The variable it should be focusing on: what Agnico Eagle and Glencore are paying, and what the drill bits are returning.

Agnico Eagle didn't just dabble — it committed real money at real prices. Agnico Eagle Mines, a C$65-billion gold producer, holds a 13.5% stake in Osisko. It built that position through public purchases on February 7, June 2, and July 30 of 2026, plus a C$12.48 million private placement at C$0.48 per share in December 2025. The latest public purchases came at prices well above C$0.48, and Agnico now holds 100.9 million shares plus 20.6 million warrants. Agnico also has pre-emptive rights to maintain its ownership threshold against future dilution. This isn't a speculative seed bet from a major. It's a structural position from a company that knows how to evaluate copper deposits, and that's been adding as the resource has grown.

Glencore entered at C$0.40, then sold part of the position at roughly C$1.60. Glencore Canada converted a US$25 million convertible debenture into Osisko equity in mid-July 2026, taking a roughly 14.4% stake at C$0.40 per unit (each unit: one share plus half a warrant). Glencore then sold 21.5 million shares through a private agreement on July 29, pocketing C$34.3 million — an exit price of roughly C$1.60 per share, about 80% above the conversion price. Glencore still retains approximately 11.9% of the company, or about 106.6 million shares, plus warrants expiring August 7. The partial exit is worth noting — it shows Glencore took profit after a 4x return on its conversion price — but it doesn't negate the signal. The remaining 11.9% stake is still the single largest position in the company. Glencore didn't abandon the position; it trimmed the top.

What the drill bits are returning is what's driving the resource — not the P/B ratio. Osisko's Gaspé Copper project in eastern Québec is the largest undeveloped copper resource in eastern North America. The April 2026 mineral resource estimate was the inflection: measured and indicated resources grew to 1.83 billion tonnes at 0.27% Cu, representing a 119% increase in contained copper metal versus the prior Indicated resource from November 2024. The upgrade wasn't from a grade revision — it was from drilling. Osisko completed 160,000 metres of drilling from 2022 through 2025 that converted untested ground into defined resource.

The 2026 drill program has continued that trend. On June 9, hole 30-1196 returned 80 metres averaging 1.93% Cu, including a 30-metre subinterval averaging 3.49% Cu. That's not porphyry-grade mineralization; that's high-grade skarn copper. And it was classified as in-pit expansion — meaning it's converting what was previously categorized as waste rock inside the modeled pit shell into new mineralization. On July 23, a separate hole returned 320 metres averaging 0.38% Cu. Seven drills are currently running across the 50,000-metre program. The company also launched a Deep Porphyry Exploration project (DPEX) at the historic Porphyry Mountain deposit, where earlier testing confirmed 852 metres averaging 0.95% CuEq.

The catalyst chain. Osisko has mapped out the next milestones. The 2026 drill program targets three objectives: upgrading remaining inferred resources to indicated category, extending mineralization toward the former Needle Mountain open pit (south/southwest), and testing depth extensions at Porphyry Mountain. A preliminary economic assessment (PEA) — the study that defines projected mine life, capital costs, operating economics, and IRR — was targeted for the 2026 calendar year according to the company's investor materials. The PEA is the gate that separates exploration from development economics. If the numbers support a viable operation, the path moves to permitting and feasibility. The Québec government has already signaled strong political support for the project.

The counterargument. The losses are real. C$159 million in the first half of 2026 is not trivial, and Osisko has no revenue. The P/B ratio of 12.8x sits far above the industry average. Simply Wall St's fair value model puts the stock at C$2.82, which would imply modest upside from the current price near C$1.92. And Glencore's partial exit — selling at roughly C$1.60 and reducing from 14.4% to 11.9% — shows that not every major holds through the whole cycle. These are legitimate bear points. The question is whether they override what the drill results, the tier-one investment prices, and the catalyst timeline are saying.

The break condition. If Osisko's PEA delivers economics that support a positive net present value, the resource's scale becomes monetizable — and the market re-rates from explorer to developer. Agnico Eagle's continued accumulation at prices 75-80% below the current level already anchors a floor below where the stock trades today. The 119% resource metal increase from the last update shows the growth trajectory hasn't stalled; it's accelerating. The risk is a prolonged burn without near-term study completion, or dilution to fund the next phase. But at a C$1.44 billion market cap with 2.07 billion pounds of contained copper in measured and indicated resources alone, the implied price per pound of in-ground copper is well below what tier-one operators pay for production assets.

The stock may need to consolidate after its recent jump before the risk/reward looks cleaner. But the math between what Agnico and Glencore paid, what the drills are returning, and where the stock currently trades is the kind of disconnect that doesn't persist when a PEA confirms the economics.
