All depends on how you want to mine. There are several options and all of the costs are listed on their well maintained website.
The website will have the most current pricing. Buckets that are seeded with gems from other areas or from EH are available, as is digging in the creek and digging in the flat areas. So it ultimately depends on what you want to do.
Fairly inexpensive fun. Five gallon buckets of dirt range from $15 to$500 and more.
There many options, small buckets, enhanced buckets etc, prices vary, their website is spot on, check it out for current information, enjoy!
