Minsur Stock – Summary and Conclusions

Minsur is an impressive company. They are one of the largest tin miners in the world with a diversified production portfolio of several operating mines and a smelting business. The company is in decent financial health, with sufficient liquidity and reasonable liability levels, although they are slightly leveraged.

I do not know enough about the tin market, so I will not invest in Minsur stock. I am very intrigued by the company’s global scale relative to its financial position. I am going to further research the tin market and revisit Minsur stock once I am more informed.

Investors can compare Minsur stock to the zinc mining company Nexa Resources.


This is not investment advice. Nothing in this analysis should be construed as a recommendation to buy, sell, or otherwise take action related to the security discussed. If I own a position in the security discussed, I will clearly state it.

This is not intended to be a comprehensive analysis and you should not make an investment decision based solely on the information in this analysis. I hope this serves as a useful starting point for a more comprehensive analysis, and hopefully draws attention to aspects of the company that were overlooked or merit further investigation. This is by no means intended to be a complete analysis. Again, this is not investment advice, do your own research.
