Even when a business is losing money, it's possible for shareholders to make money if they buy a good business at the right price. By way of example, Koryx Copper (CVE:KRY) has seen its share price rise 122% over the last year, delighting many shareholders. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.
In light of its strong share price run, we think now is a good time to investigate how risky Koryx Copper's cash burn is. For the purposes of this article, cash burn is the annual rate at which an unprofitable company spends cash to fund its growth; its negative free cash flow. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.
A company's cash runway is calculated by dividing its cash hoard by its cash burn. In August 2025, Koryx Copper had CA$30m in cash, and was debt-free. Looking at the last year, the company burnt through CA$14m. Therefore, from August 2025 it had 2.2 years of cash runway. Arguably, that's a prudent and sensible length of runway to have. You can see how its cash balance has changed over time in the image below.

Because Koryx Copper 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. Remarkably, it actually increased its cash burn by 247% in the last year. With that kind of spending growth its cash runway will shorten quickly, as it simultaneously uses its cash while increasing the burn rate. Clearly, however, the crucial factor is whether the company will grow its business going forward. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.
While Koryx Copper does have a solid cash runway, its cash burn trajectory may have some shareholders thinking 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. 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).
Koryx Copper's cash burn of CA$14m is about 6.4% of its CA$219m market capitalisation. Given that is a rather small percentage, it would probably be really easy for the company to fund another year's growth by issuing some new shares to investors, or even by taking out a loan.
Even though its increasing cash burn makes us a little nervous, we are compelled to mention that we thought Koryx Copper's cash burn relative to its market cap was relatively promising. Cash burning companies are always on the riskier side of things, but after considering all of the factors discussed in this short piece, we're not too worried about its rate of cash burn. On another note, Koryx Copper has 4 warning signs (and 3 which are significant) we think you should know about.
