There's no doubt that money can be made by owning shares of unprofitable businesses. For example, although software-as-a-service business Salesforce.com lost money for years while it grew recurring revenue, if you held shares since 2005, you'd have done very well indeed. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

So should First Mining Gold (TSE:FF) shareholders be worried about its cash burn? In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

Check out our latest analysis for First Mining Gold

How Long Is First Mining Gold's Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. In June 2019, First Mining Gold had CA$11m in cash, and was debt-free. Looking at the last year, the company burnt through CA$8.6m. Therefore, from June 2019 it had roughly 16 months of cash runway. While that cash runway isn't too concerning, sensible holders would be peering into the distance, and considering what happens if the company runs out of cash. You can see how its cash balance has changed over time in the image below.

How Is First Mining Gold's Cash Burn Changing Over Time?

First Mining Gold didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. So while we can't look to sales to understand growth, we can look at how the cash burn is changing to understand how expenditure is trending over time. Even though it doesn't get us excited, the 40% reduction in cash burn year on year does suggest the company can continue operating for quite some time. Clearly, however, the crucial factor is whether the company will grow its business going forward. So you might want to take a peek at how much the company is expected to grow in the next few years.

How Hard Would It Be For First Mining Gold To Raise More Cash For Growth?

Even though it has reduced its cash burn recently, shareholders should still consider how easy it would be for First Mining Gold to raise more cash in the future. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. Many companies end up issuing new shares to fund future growth. By looking at a company's cash burn relative to its market capitalisation, we gain insight on how much shareholders would be diluted if the company needed to raise enough cash to cover another year's cash burn.

First Mining Gold has a market capitalisation of CA$134m and burnt through CA$8.6m last year, which is 6.4% of the company's market value. That's a low proportion, so we figure the company would be able to raise more cash to fund growth, with a little dilution, or even to simply borrow some money.

So, Should We Worry About First Mining Gold's Cash Burn?

The good news is that in our view First Mining Gold's cash burn situation gives shareholders real reason for optimism. Not only was its cash burn reduction quite good, but its cash burn relative to its market cap was a real positive.
