Diamonds in the Rough? Mountain Province's Price Revision Sparks Valuation Concerns

Mountain Province Diamonds' recent correction of its Q2 2024 average selling price per carat—from an initially reported CA$166 to a revised CA$102—has sent shockwaves through investor circles. The 38.6% downward revision, which translates to a loss of CA$64 per carat, underscores the fragility of valuations in the diamond industry and raises critical questions about the company's path forward.

The corrected figures, disclosed in a July 10, 2025, update to the original news release, highlight a material error in pricing data. While the revision does not alter other financial metrics, such as production volumes or costs, the drop in selling prices directly impacts revenue projections and investor confidence. For Mountain Province, which operates a 49% stake in Canada's Gahcho Kué mine—one of the world's largest diamond mines—the stakes are high.

Valuation at Risk: The Math of Lower Prices

Mountain Province's Gahcho Kué mine comprises key kimberlite deposits: Kelvin, Faraday 1-3, and Faraday 2. The revised sales price has immediate implications for the valuation of these reserves.

• Kelvin kimberlite: Contains 13.62 million carats, valued at US$63 per carat under the original price. With the corrected price of US$74 (CA$102), the per-carat value actually increases slightly due to currency fluctuations. However, this is a minor bright spot.
• Faraday 2 kimberlite: Originally valued at US$140 per carat, now revalued at US$102 (CA$102), reducing its per-carat worth by nearly 27%.
• Faraday 1-3 kimberlites: Decline from US$75 to US$74 per carat, a marginal drop but indicative of industry-wide softness.

The revised prices suggest that Mountain Province's total resource value has been downgraded, particularly for its higher-value Faraday 2 deposits. This could pressure the company's asset-based valuation metrics, such as net asset value (NAV) per share, which investors often use to gauge undervalued mining stocks.

Financial Woes and Strategic Crossroads

Beyond valuation, the company faces operational and financial headwinds. Mountain Province reported net losses in recent quarters, a negative P/E ratio, and a steep 47.8% YTD stock decline. Its market cap of just C$12.74 million reflects investor skepticism about its ability to sustain profitability amid declining diamond prices and production volumes.

The company's efforts to secure capital through refinancing highlight its liquidity challenges. However, with technical indicators neutral and the stock's low trading volume (94,753 shares on average), institutional investors appear hesitant to commit.

Investor Confidence and the Bigger Picture

The price revision raises red flags about transparency. While Mountain Province attributes the error to a data misstatement, the incident could erode trust, particularly in an industry where accurate reporting is critical for resource valuation. For example, if future discoveries or production data are similarly misreported, the consequences could be severe.

Yet, the company's partnerships—most notably with De Beers Canada—remain a strategic advantage. The Gahcho Kué mine, a joint venture with one of the world's diamond giants, provides operational stability and access to De Beers' marketing network. Additionally, Mountain Province's focus on high-grade kimberlites like Faraday 2 could still yield returns if diamond prices rebound.

Investment Takeaways

1. Caution Advised: The corrected sales price and ongoing financial struggles suggest Mountain Province is a high-risk play. Investors should prioritize downside protection, such as stop-loss orders, or wait for clearer signs of stabilization.
2. Valuation Sensitivity: The stock's valuation hinges on diamond price assumptions. Bulls might argue that the revised figures are a one-time correction, but bears will point to structural declines in demand (e.g., Chinese market softness) and oversupply risks.
3. Watch for Catalysts: Key events include production updates from Gahcho Kué, progress on refinancing, and broader trends in diamond pricing. A recovery in Faraday 2's per-carat value could be a critical turning point.

Final Verdict

Mountain Province's revised sales figures are a stark reminder of the risks in resource equities: valuations can unravel quickly if commodity prices or operational metrics sour. While the company's asset base remains substantial, its ability to navigate financial and market challenges will determine whether it becomes a “diamond in the rough” or a cautionary tale. For now, the path is narrow—and littered with pitfalls.

Investors looking for exposure to diamonds might instead consider larger, more diversified players like De Beers parent company Anglo American (AAL.L), which have greater financial flexibility. For Mountain Province, the road to recovery is long—and the corrected sales price is just the first bump in the road.
