How Is Great Western Mining's Cash Burn Changing Over Time?

Because Great Western Mining 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. In fact, it ramped its spending strongly over the last year, increasing cash burn by 162%. It's fair to say that sort of rate of increase cannot be maintained for very long, without putting pressure on the balance sheet. Great Western Mining makes us a little nervous due to its lack of substantial operating revenue. We prefer most of the stocks on this list of stocks that analysts expect to grow.

Can Great Western Mining Raise More Cash Easily?

While Great Western Mining 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. Many companies end up issuing new shares to fund future 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.

Since it has a market capitalisation of €18m, Great Western Mining's €2.3m in cash burn equates to about 13% of its market value. Given that situation, it's fair to say the company wouldn't have much trouble raising more cash for growth, but shareholders would be somewhat diluted.
