As the economy begins to reopen after countless lockdowns and mine closures, the copper mining industry is poised to soar. In the coming future, experts project that the price of copper will continue to rise due to limited supply and rising demand. Copper is a key raw material for the production of high-tech products which are only becoming more and more valuable as technology advances.

With the price of copper projected to rise, many investors likely want to get in on the action and perhaps earn huge dividends in the coming years. However, it can be difficult to tell which copper mining stocks to purchase since there are many factors to consider. Current market price and price growth rate are too good indicators, but another valuable method of judging the viability of a stock investment is its price-to-earnings (P/E) ratio.

Put simply, a P/E ratio is the stock’s current share price divided by its earnings per share (EPS) over the course of a year. For example, let us say your stock is $60 per share and your EPS is $3. This would give you a P/E ratio of 20. This means that the investor will pay $20 per $3 in earnings.

As with other stocks, some of the best copper investments you can make will be based off of a low P/E ratio. A low P/E ratio means that you will pay less money for each profit earned.

Here are some options for the three best copper companies to invest in for the September of 2021.

Turquoise Hill Resource Limited (TSX:TRQ)

Turquoise Hill Resources is a Canadian mining company that explores and develops copper and gold mines across Asia and Australia. Currently, its primary source of profit is the You copper-gold mine in Southern Mongolia. As of the first quarter of 2021, the net income attributable to the company owners went up by 423.9%.

The company’s current stock price is about $19, and its current P/E ratio is 5.2, the lowest copper stock P/E ratio this quarter.

Copper Mountain Mining Corporation (TSX:CMMC)

The Copper Mountain Mining Corp is a domestically owned mining company with a focus on copper mining in southern British Columbia. The company released its financial results in late April and recorded a net income of CAD$52.1 million, a leg up from the net loss of CA43.5 million reported a year ago. The 227.3% rise in revenue is massive, and according to sources is projected to rise.

Its P/E ratio is 7.3 which is slightly higher than Turquoise Hill, but the stock price is only about $3.25 per share.

Capstone Mining Corp (TSX:CS)

Capstone is a more diversified mining company than the other two, mining a variety of different minerals like gold, zinc, iron, lead, as well as copper. The company currently has operations on a global scale, with mining projects across the United States, Chile, and Mexico. Capstone released its financial results last April for the first quarter of 2021 and reported a net income of $127 million.

Capstone’s P/E ratio is one of the highest on the list, but the stock is only sitting around $5.60 and is one of the most profitable mining companies at the moment. It also still remains the 3rd lowest P/E ratio available.
