Hemlo Mining (TSX:HMMC) Slides On Power Outage As Valuation Questions Grow

Hemlo Mining (TSX:HMMC) has been in focus after reporting a temporary electrical outage at an underground substation at the Hemlo Gold Mine on September 4, 2026. The incident affected part of its Alimak production area.

That outage coincided with a sharp pullback in Hemlo Mining’s recent trading, with the share price down 6.31% over the past day and 17.61% over the past week, following a 36.60% year-to-date share price return and a very large 1-year total shareholder return that points to strong momentum over the longer period.

Scan how Hemlo Mining stacks up against other producers under fresh operational headlines by comparing it to our hand picked 36 elite gold producer stocks in similar situations.

After a sharp pullback, Hemlo Mining now trades well below both its analyst target and intrinsic estimate range. Is that discount a fair reflection of risk, or has the price slipped too far from fair value?

Price-to-Earnings of 88.6x: Is it justified?

Hemlo Mining now trades at CA$6.83 per share, while screening as expensive on earnings with a P/E of 88.6x compared with both peers and the wider Canadian metals and mining group.

The P/E ratio compares the current share price with the last 12 months of earnings per share, so a higher figure usually reflects strong profit expectations or temporarily low earnings. For a gold producer like Hemlo Mining that only recently moved into profitability and carries a large one off loss of $15.1m in its latest 12 month period to 30 June 2026, that single snapshot can be skewed by unusual items.

Analysts are forecasting annual earnings growth of 40.8% and revenue expansion of 23.7%, and the SWS DCF model currently estimates fair value at CA$39.55, which is well above the current CA$6.83 price. Against that backdrop, the P/E of 88.6x screens very elevated versus the Canadian metals and mining industry average of 17x, the peer group average of 24.9x and the estimated fair P/E of 26.1x that the market could move toward over time if cash flows and profitability normalise.

Result: Price-to-Earnings of 88.6x (OVERVALUED)

Still, a single-mine profile at Hemlo Mining and the recent electrical disruption at the Hemlo gold operation could both pressure sentiment if setbacks persist.
