Thare are 2 different areas with unique water characteristics for Sombrero Butte and for the Miami properties
This is the river near Sombrero

Notice it only flows during rainy seasons and we know where those are headed
Also notice the recent court action denying one of our major defense establishments access to this river
This is the region that covers the Miami properties

Here again, access to water is tightly managed and competes in this case with the Phoenix metro area
There may be ample water for an explorer
Any mine developer wil extract a hefty holdback for the uncertainties associated with water availability
