There's no doubt that money can be made by owning shares of unprofitable businesses. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

Given this risk, we thought we'd take a look at whether Discovery Silver (TSE:DSV) shareholders should be worried about its cash burn. For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

Does Discovery Silver Have A Long Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Discovery Silver last reported its June 2024 balance sheet in August 2024, it had zero debt and cash worth CA$37m. In the last year, its cash burn was CA$31m. That means it had a cash runway of around 14 months as of June 2024. 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. Depicted below, you can see how its cash holdings have changed over time.

How Is Discovery Silver's Cash Burn Changing Over Time?

Because Discovery Silver isn't currently generating revenue, we consider it an early-stage 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 34% reduction in cash burn year on year does suggest the company can continue operating for quite some time. While the past is always worth studying, it is the future that matters most of all. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Hard Would It Be For Discovery Silver To Raise More Cash For Growth?

While Discovery Silver is showing a solid reduction in its cash burn, it's still worth considering how easily it could raise more cash, even just to fuel faster growth. Companies can raise capital through either debt or equity. Commonly, a business will sell new shares in itself to raise cash and drive growth. By comparing a company's annual cash burn to its total market capitalisation, we can estimate roughly how many shares it would have to issue in order to run the company for another year (at the same burn rate).
