A Look at Capstone Copper (TSX:CS) Valuation Following Sustainability Milestones and Mantoverde Launch

Capstone Copper (TSX:CS) has released its 2024 Sustainability Report, highlighting a series of achievements on the environmental and operational front. These include newly launched production at the Mantoverde concentrator, steps forward in renewable energy adoption, and improved water management.

See our latest analysis for Capstone Copper.

Capstone Copper’s year has been eventful, with momentum building around the launch of its Mantoverde concentrator and strategic deals such as the sale of a 25% stake in the Santo Domingo Project. Despite some large insider sales, the 90-day share price return of 43.5% and a strong five-year total shareholder return of 549.7% reflect sustained outperformance. However, the one-year total return softened to 6%.

If you’re looking to expand your search after Capstone’s surge, now is a great opportunity to discover fast growing stocks with high insider ownership.

But with the stock up sharply over the past three months and trading near its price target, the big question is whether Capstone Copper is still undervalued, or if the market has already factored in its future upside.
