The San Domingo Gold #1 Placer Claim is a 20.00 acre unpatented placer claim located in the historic San Domingo Mining district within Maricopa County, Arizona.  


The San Domingo wash is extremely competitive for placer claims due to the year round mining season, large amounts of documented gold reserves, and extremely rich ore grades for gold in both fine gold and nugget form.


With Gunnison Gold Prospecting owning 4 unpatented placer claims contiguously thru the San Domingo wash this placer location is ideal for a small operator wanting to purchase all four claims of 80 acres for 140,000 USD total for uninterrupted and continuous mining operations. Or these the San Domingo claims can be sold individually; with a perfect location for both small scale miners and future miners, to mid-cap mining companies.


With extremely valuable historic documentation and very limited production without the high tech gold recovery systems miners now have access to today the San Domingo Claims are a diamond in the rough for a miner wanting to leverage this unexploited gold deposit to its fullest potential.


The San Domingo Gold #1 claim can be dry washed with recreational equipment to full scale mining equipment and everywhere in between.  


Additionally, the San Domingo Gold #1 claim is a nugget hunters paradise with metal detecting due to the large and course gold found within the claim boundaries.


Featuring a dry wash over 300 feet wide and numerous feeder gulches flowing into the main dry wash.  Large banks on either side of the dry wash are excellent locations for metal detecting.


Enjoy a year round mining season and great drivable access to the claim.  

From Phoenix the claim is a short 45 minute drive.


Additionally, camping is allowed onsite for up to 14 days at a time without a permit.
