I believe they are in 105H9. There are 5 lapsed claims specifically called "3Ace" I hope it's not them, because they don't appear to be registered!

There is also a strip of 20 claims encompassing about 4.5 kilometers right next to these lapsed claims called "Ace." If it's these only, then it's not a big property and likely that the mineral will stray off the property.

If the neighbouring "King" claims are included, it is a substantial property. I believe Selwyn owned a lot of gold claims along Nahanni Range Road. I'll see if I can figure out if the "King" claims are theirs.
