The Goldbay Hardrock experience is like no other.
This is a fabricated white proprietary concrete/cement mix with natural quartz crystals and rock.
There are 18k plus gold veins encased in the block as well as some natural gold ore from Greens Creek in Alaska (the gold ore is silver/gold and quite unique)
The $99 block has just over 1 1/2 grams of gold guaranteed and its up to you to get it ALL out!
You can use metal detectors or pinpointers on many of these to locate the larger pieces encased in the rock 🙂
