Superdow- I don't think you have a good grasp of overburden yet. What you need to look at is the stripping ratio as a rule of thumb to use lacking other information about the economics of the deposit. (Ton of ore)/(tons of overburden needed to remove to get to the ore) So for example-if you have 300 meters of overburden and only 50 meters of minerlization-that works out to approximately 50/300 or .1666- very bad. If you have 300 meters of overburden but you have 1000 meters of ore- 1000/300 a stripping ratio of 3.33. Very good. Understand? With a breccia pipe with narrow horizontal dimensions and tremedous vertical dimensions-overburden won't be a problem. Don't let the Bullies of the thread confuse you on this issue. The yet to be discovered porphyry ore deposit will have very large horizontal dimensions-much more likely overburden will be a problem. (ie underground mining maybe the preferred option instead of strip mining.) Of course-what does it matter-it won't be Medinah who will find it!
