Please excuse my lack of knowledge, but trying to work out what would be needed for AUL to be a 100mil market cap company. I get the share price needs to be 0.054c based on current shares. but after searching i have found that a rough formula is 4 times earnings, meaning AUL would need to make 25mil a year to be worth 100mil? so then at $1700 bucks an ounce roughly, we would need to mine 15k ounces. Is this right as a rough way of looking at it? Or am i completely wrong? Any help would be appreciated. New to valuing a company. I Also get that expenses need to be included. Grade and waste are all factors, But just as a very rough idea.
