There's no doubt that money can be made by owning shares of unprofitable businesses. For example, although Amazon.com made losses for many years after listing, if you had bought and held the shares since 1999, you would have made a fortune. But while the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.
So should Aztec Minerals (CVE:AZT) 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'. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.
You can calculate a company's cash runway by dividing the amount of cash it has by the rate at which it is spending that cash. As at March 2026, Aztec Minerals had cash of CA$6.5m and no debt. In the last year, its cash burn was CA$6.5m. Therefore, from March 2026 it had roughly 12 months of cash runway. That's quite a short cash runway, indicating the company must either reduce its annual cash burn or replenish its cash. Depicted below, you can see how its cash holdings have changed over time.

Because Aztec Minerals isn't currently generating revenue, we consider it an early-stage business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. In fact, it ramped its spending strongly over the last year, increasing cash burn by 116%. It's fair to say that sort of rate of increase cannot be maintained for very long, without putting pressure on the balance sheet. Aztec Minerals makes us a little nervous due to its lack of substantial operating revenue. So we'd generally prefer stocks from this list of stocks that have analysts forecasting growth.
Since its cash burn is moving in the wrong direction, Aztec Minerals shareholders may wish to think ahead to when the company may need to raise more cash. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund growth. We can compare a company's cash burn to its market capitalisation to get a sense for how many new shares a company would have to issue to fund one year's operations.
Aztec Minerals has a market capitalisation of CA$61m and burnt through CA$6.5m last year, which is 11% of the company's market value. As a result, we'd venture that the company could raise more cash for growth without much trouble, albeit at the cost of some dilution.
On this analysis of Aztec Minerals' cash burn, we think its cash burn relative to its market cap was reassuring, while its increasing cash burn has us a bit worried. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future. On another note, Aztec Minerals has 5 warning signs (and 4 which make us uncomfortable) we think you should know about.
