Almost two years ago, we rounded the corner at the Gift Show and found George
Marchacos and his fabulous mining sluice. We were immediately intrigued and - while
there was no direct connection to an arts & crafts studio - we instinctively knew we had
to have one. Running water, dirt, cool rock treasures....What child could resist?
Our gut instinct proved correct and it was an overnight success. Not only did it set us
apart from other arts & crafts studios, it added another attraction for boys - a harder
target to attract in our industry. While we have yet to really tap the scout troops and
classrooms, they are beginning to find us on their own. The mining sluice is offered to
walk-ins but it's the birthday party add-on that has been key in increasing revenue on
existing sales.
Currently averaging about 350 bags of mine rough a month, the kids keep on coming
back for more. Collecting and trading is quickly becoming a hobby we hope to
proliferate.
Working with George and Cold River Mining has been a positive and rewarding
experience. They are extremely service-oriented and the price/value of the mine
rough/rocks is beyond comparison. Our long term plans include multiple locations and
none of them will be complete without a mining sluice. We hope to maintain our
relationship with Cold River Mining for a long time to come. Thanks Cold River Mining!

Dear George & Adam,
We wanted to take this time to tell you what a pleasure it is to work with you. You have
been very flexible, positive, and helpful from the beginning. You have truly helped us to
find a use for a building that for years had been used simply as storage.
Since bringing Mt. Mooselaukee Mining Co. to our campground, we have had such a
positive feedback. Your novel idea of a buried mine has really been a hit. The kids love
putting on the hard hats and mining lamps and going on a "treasure hunt" into the
mine. In fact we have as many parents as kids go in because they think it is so cool to
be a part of it too.
We cannot thank you enough for all the help and insight you have given us. We look
forward to an on-going relationship for years to come.
Thanks for everything,
The Clark Family







I met George Marchacos at the 2003 IAAPA Show in Orlando, FL. George designed and
developed a mining, panning, and digging experience at my business in the Spring of
2004 for the upcoming tourist season. It turned out to be extremely successful from both
a revenue generating and entertainment perspective. George has also been a complete
resource for rocks, fossils and all types of rockhound merchandise.
On a personal level, George became a very good friend of mine and many staff members
of the Wall Drug Store. I admire his character and work ethic. I feel that I know and trust
George as much as anyone that I have known during my business career.
I give this man and his two sons my highest recommendation if you have the opportunity
to do business with him. I am sure you will enjoy them as much as I have.
Sincerely,
Ted Hustead, President
Wall Drug Store

Dear Cold River Mining Co,
We are very pleased to report that after our first summer with our "Jellystone Gems
Mining Company" attraction in operation here at our campground, the response from
our campers was very favorable. We feel the key to our success would be the location
of the sluice by the Ranger Station and the main roadway entering the park. We also
held a daily demonstration free of charge that demonstrated how to sluice successfully.
The parents enjoyed it as much as the kids!
Thanks for the great service this summer! We look forward to working together with you
and your company in the future!
Yours truly,
Peter L. Clark

Dear Cold River Mining Co.
Just wanted to drop you a note letting you know how much our guests are enjoying the
Gem Mining operations we purchased from your company. This is part of our most
popular party package which also includes inflatables and rock climbing. We call this our
Adventurer Experience and I receive many positive comments from both the kids and the
parents. I think the fact that it is a activity where the parents and children can participate
together makes it even better experience.
I see this as an investment that will provide a fairly quick ROI and most importantly
provides a long term revenue stream and significantly differentiates us from our
competition. Parents often comment about how they used to have to drive the kids to the
mountains to enjoy this experience. Thanks so much.
Sincerely,
Ken Connor
