You were almost there. Just cross the creek and go up a little hill and you are right in the claim. Most people go into the trail at the right as you crest that hill. The trail goes down to Castle Creek. Walk around and you will see many digs.

Thank you Jon. Wasn't quite sure, and didn't want to do any panning until we were.

This maybe a little late but as you past those buildings the bike trial will go straight and the road will go up to the left. once you go up the hill and turn left on the curve start looking for a dirt road that goes down to the right.  This road is in rough condition but if  you walk down it there will be a sign saying Marry Ann.  There is a sign or I should say a square piece of wood nailed to a tree that does have gpaa etched in it on the main road it is hard to see. So just walk down the entry road and find the good sign close to the creek.

Thank you Josh!! We were right there, we seen a white pickup down that dirt road and wondered if that was the pace, now we know. Thanks for your help!!
