The Gold Star mine is just east of Skull Valley. With this weather forecast there is no reason that GDSM/WSRA cannot work.
Here is the 7 day forecast and it is cooler than many states. Not a single 100 degree day in sight and it does not get that hot until mid afternoon. Many outside workers start at 5:00 AM and are done by 2:00 to avoid working during the heat of the afternoon. And this is a DRY desert heat with low humidity.
