The concept of the park is awesome. It really does attempt to bring the mining history to life. Unfortunately, the execution isn't quite there. The exhibits in the visitor center are mostly donated artefacts, without much effort to tie them together into a coherent narrative. The grounds of the park have some great points of interest, but the signs are so limited in number, that its often impossible to navigate and know where anything is. The map in the brochure is only so helpful, but when there are literally dozens of foot paths (many of which date back to the mining era), its often unclear where you're walking.
That said, the park is quite interesting. Improving the signs (both inside the visitor center, and on the park grounds) would make a huge difference. We spent just over an hour, however its certainly possible to spend much more time if you're determined to see everything.
