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?
So, the natural question for Unico Silver (ASX:USL) shareholders is whether they should be concerned by its rate of cash burn. In this article, we define cash burn as its annual (negative) free cash flow, which is the amount of money a company spends each year to fund its growth. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.
Does Unico Silver Have A Long Cash Runway?
A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Unico Silver last reported its December 2025 balance sheet in March 2026, it had zero debt and cash worth AU$67m. Looking at the last year, the company burnt through AU$30m. So it had a cash runway of about 2.2 years from December 2025. Arguably, that's a prudent and sensible length of runway to have. The image below shows how its cash balance has been changing over the last few years.

How Is Unico Silver's Cash Burn Changing Over Time?
Because Unico Silver 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. Its cash burn positively exploded in the last year, up 489%. Given that sharp increase in spending, the company's cash runway will shrink rapidly as it depletes its cash reserves. While the past is always worth studying, it is the future that matters most of all. So you might want to take a peek at how much the company is expected to grow in the next few years.
Can Unico Silver Raise More Cash Easily?
While Unico Silver 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. Companies can raise capital through either debt or equity. Commonly, a business will sell new shares in itself to raise cash and drive 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.
Unico Silver's cash burn of AU$30m is about 5.2% of its AU$576m market capitalisation. 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.
