We offer guided mineral collecting for the serious mineral collector of Herkimer Diamonds.
Beginning Friday, May 29th, we will be open for camping only. Although we will continue to be closed to the public for day mining, those registered to camp will be allowed to purchase a mining ticket. If you would like to reserve a campsite, please call our office at (315) 891-3855 between 9AM and 5PM. As a reminder, there is a limit of 6 people per campsite. At this time, only registered guests will be allowed at the campsites (no visitors). In addition, we have also made the difficult decision to not accept reservations for the Guided Mining (trophy dig) experience for this year's mining season.
Below is a list of COVID-19 guidelines that we have established to help keep everyone safe:
1) Anyone entering the mine office must wear a mask.
2) We ask that only one person per group enter the mine office to check-in for camping, purchase mining tickets, rent tools, etc.
3) Social distancing (6 foot distancing) should be observed at all times.
4) No more than 6 people will be allowed in the mine office at any given time.
The safety of our staff and patrons remains our top priority and we will make a further announcement on our website and Facebook page as soon as we know when we will be able to open to the public for day mining.
Thank you for your patience, understanding, and continued support.

Ace of Diamonds Mine
The success of your collecting trip is assured
before you even start! Before your arrival we will have removed up to
20 feet of glacial overburden and
up to 8-10 feet of limestone bedrock. Upon your arrival the pocket layer,
which is about 24 inches thick, will be exposed. To make this possible
we have on site at the mine:
three 100,000-pound excavators
a Cat track loader
a Cat bulldozer
a Mack tandem axle dump truck
an air compressor
a rock drill
jackhammers and other related tools
You and your guide will drill the pocket layer until the drill drops
into a large cavity. Then a 350 ton hydraulic rock splitter is inserted
in the drill hole and the rock cracks as if by magic! These cavities
usually range from 1 to 2 1/2 feet or even larger and will contain from
approximately 2 dozen or more crystals. Sometimes up to several hundred
At this point you can start removing the crystals that have been waiting
for you for about 450 million years. Your guide will assist you, if you
desire, in removing your crystals from the pocket and help you wrap them
for your trip home.
Since this is a personalized service, reservations and a $350 deposit
are required. The total cost of your once-in-a-lifetime experience is
$1,900. (Credit Cards are acceptable for deposit only). Payment in cash or Travelers’ checks, USA funds. No personal checks. If you are satisfied with your experience, a 5% to 10% gratuity to your guide is standard practice.
Rock collecting, like most thrill sports, has a certain amount of inherent
risk and collecting is done at your own risk. We are, however, very safety
conscious. For your own protection, you should wear suitable mining
clothes, work shoes, safety glasses, ear protectors, and gloves. Flip flops or other open-toed shoes are not allowed.
