Combining Classic Mineral Exploration with State of the Art Technology
Does anyone recall JB's previous mention of oil and gas potential in the Tombstone/Bisbee area?
I recall seeing a map of two potential deposits extending from the Sierra Madre in Mexico into SW New Mexico, and another smaller one paralleling the first and extending from Mexico into SE Arizona. ...can't find that link now, though I've looked twice.
Anway, for those who simply have to read everything they can on the geology of SE Arizona, here's something which may eventually bring new kinds of interest to the area.
"The Pedregosa and Bisbee basins in south-eastern Arizona contain up to 25,000 ft of largely marine strata of Cambrian through Cretaceous age. The Bisbee basin of Cretaceous age generally overprints the older Pedregosa basin. Paleozoic rocks and regional unconformities in the Pedregosa basin are similar in age and character to those in the Permian Basin of West Texas, where truncated strata beneath the regional unconformity form important hydrocarbon traps."
"Lower Cretaceous marine rocks contain reefs similar to those that produce oil in Texas and Mexico. Upper Cretaceous rocks in Mexico about 15 miles south of Douglas contain coal seams that may yield coal bed methane in the vicinity of Douglas. Evidence for hydrocarbons in the Pedregosa and Bisbee basins includes shows of oil and gas in wells, including 450 ft of oil-cut mud in one well, and petroliferous rocks. Colour changes in conodonts show that the Paleozoic rocks in south-eastern Arizona are within the oil and gas window."
"Potential of the Pedregosa and Bisbee basins is considered fair to very good. Interstate pipelines cross the area and provide a market outlet. Large blocks of state trust and fee land are available. Drilling depths range from 4,000 ft to 15,000 ft or more. Drilling density is about one well/395 sq miles."

PLEASE NOTE HERE THAT THE ABOVE LINK PREDATES THE DEVELOPMENT AND MODERN APPLICATION OF FRACKING, so recoveries of hydrocarbons could be greatly more significant than suggested by the estimated "one well/395 sq miles".
I would think that company attorney's asked JB to stop talking about this, but it remains in the back of my mind. By the way, I don't think Eurogas having interests in the area is at all related, but it could be. Time will tell.
