Osisko Metals (TSX:OM) Looks Fully Valued Following Gaspé Copper Drill Expansion Results

Osisko Metals (TSX:OM) has released new drill results from its 2026 program at the Gaspé Copper Project, combining infill hits with new expansion intercepts beyond the existing resource model.

These fresh drill results land after a powerful run in Osisko Metals’ shares, with a year-to-date share price return of 103.8% and a very large 3-year total shareholder return of about 8x. However, momentum has cooled recently, with the 30-day share price down 7.47% and the latest move a 1-day gain of 1.90% to CA$1.61.

Osisko Metals now pairs a high profile copper asset with a share price that has already multiplied in recent years. The central question is straightforward: Are you paying up for quality drilling progress, or still getting the project at a discount?

Preferred Price-to-Book Multiple of 36.8x: Is It Justified?

Osisko Metals now trades on a very rich P/B tag, with the stock at CA$1.61 and the latest data pointing to a 36.8x multiple on book value. That sits alongside a share price that has already delivered multi year gains and a business that remains loss making with no meaningful revenue reported yet.

P/B compares the market value of the equity with the accounting value of net assets on the balance sheet. For early stage resource developers like Osisko Metals, that ratio often reflects what investors think the underlying projects could be worth in the future rather than what has already been earned. A high reading can signal strong expectations for future drilling success or project advancement, while a low figure can hint that the market assigns little value to the asset base.

In this case, the market is paying a substantial premium. The Canadian Metals and Mining group averages a P/B of 2.4x, and Osisko Metals also sits well above a peer average of 10.9x. Revenue is forecast to grow at 208.2% per year and analysts expect the business to remain unprofitable over the next 3 years, so a lot of optimism around the Gaspé Copper Project is already embedded in that 36.8x reading.

Result: Price-to-book of 36.8x (OVERVALUED).

Still, the story can crack if drilling results disappoint or if prolonged losses, with net income currently at a loss of CA$192.669 million, cause investors to reassess expectations.
