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. For example, Zacatecas Silver (CVE:ZAC) shareholders have done very well over the last year, with the share price soaring by 150%. 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 notwithstanding the buoyant share price, we think it's well worth asking whether Zacatecas Silver's cash burn is too risky. 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). Let's start with an examination of the business' cash, relative to its cash burn.
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 September 2025, Zacatecas Silver had cash of CA$2.8m and no debt. Looking at the last year, the company burnt through CA$1.9m. Therefore, from September 2025 it had roughly 18 months of cash runway. That's not too bad, but it's fair to say the end of the cash runway is in sight, unless cash burn reduces drastically. You can see how its cash balance has changed over time in the image below.

Zacatecas Silver 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. While it hardly paints a picture of imminent growth, the fact that it has reduced its cash burn by 28% over the last year suggests some degree of prudence. Zacatecas Silver 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.
Even though it has reduced its cash burn recently, shareholders should still consider how easy it would be for Zacatecas Silver to raise more cash in the future. Companies can raise capital through either debt or equity. Many companies end up issuing new shares to fund future 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).
Since it has a market capitalisation of CA$31m, Zacatecas Silver's CA$1.9m in cash burn equates to about 5.9% of its market value. 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.
The good news is that in our view Zacatecas Silver'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. Based on the factors mentioned in this article, we think its cash burn situation warrants some attention from shareholders, but we don't think they should be worried. Taking a deeper dive, we've spotted 4 warning signs for Zacatecas Silver you should be aware of, and 2 of them can't be ignored.
