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.
