Could be that simple, I read it more as;
Formula: HNO3
Molar mass: 63.01 g/mol
However, moved about 2200lbs of soil yesterday by hand and 64 gallon cart and then about 50 12" by 6" concrete cylinders by legs/shoulders from work to home. Add in a 3am phone call to the homeland. Then read couple of reports on the Kibby basin at work today. A gravity survey model report and the Spartan MT survey on the Belmont site, the latter being the most insightful as far as learning to understand different survey reports. The layout of the reports were detailed, complete and simply explained for the not so experienced. Glad I read them.
I have to say some of this has some fault of yours & a few others over at gln. I was running over a few of their threads, recent results and some believing (not you) that survey info as set in stone.
Anyway, I'm nackered, old and sore, so maybe I'm reading too much into Hole Number 3.
