The market's sentiment towards QMN doesn't appear to have changed much after the Tank Hill drilling results. My enthusiasm about encouraging drilling results is still tempered by my ignorance about what it all means from a commercial point of view. In very simplistic terms, QMN could have let's say 100 000 tons of copper spread around several deposits in something around 10 000 000 tons of ore. Is this worth anything?
How much resource at a little under 1% copper, do you need for a potentially profitable mine?
Are there any similar scale Australian operations for comparison purposes?
