I did get an email and message from John Hill and he said, " I was recently at the place where google says the supply store is. I was told by the lady who works at the gun store that housed Eureka that he was running the store mainly out of his house. She gave me his card (he's also a CC firearms instructor) Ken Walls 775-846-6357 i guess he lives a little north of Reno. Good luck!"
So I continued to call Eureka Prospecting and Ken did call me back. I was relieved that he might be able to help with renting out a drywasher if one is available at the time of my trip. I was very grateful that I got a response and it sounds promising. Ken was very nice and helpful and I look forward to doing business with him and maybe finding some of the yellow stuff with one of his drywashers.
I also got a message from Steve Gregory with GPAA of Northern Nevada and he was very helpful as well.
Thank you John Hill, Steve Gregory with GPAA of Northern Nevada and Ken Walls with Eureka Prospecting.
