Capstone Mining Stock – 3 Metrics to Consider

Debt to Equity Ratio

Total Liabilities/Total Share Holder Equity

$460 million/ $871.3 million =.52

A debt to equity ratio of .52 indicates that Capstone has relevant amounts of debt in its capital structure, but uses more equity financing then debt financing. They should not be overly reliant on any one form of financing in the future.

Price to Book Ratio

Current Share Price/Book Value per Share.

$.53/$2.06 = .26

Based in fully diluted shares outstanding, Capstone has a book value per share of $2.06. At the current market price this implies a price to book ratio of .26, meaning the company’s stock currently trades at a significant discount to the book value of the company.

Working Capital Ratio

Current Assets/Current Liabilities

$123.4 million/ $55.4 million = 2.2

A working capital ratio of 2.2 indicates adequate short term liquidity. Capstone should not have a problem meeting its short-term obligations.

Capstone has two solid producing properties as well as an intriguing exploration portfolio. The company is operating at a net loss and debt levels are concerning. Dilution is also a concern.

I am not currently investing in Copper stocks, so I will not be investing in Capstone, however due to the company’s undervaluation based on book value, I will continue to monitor the stock.
