Gold mining holiday...?

If you ever been to Malaysia before, you will notice that there's a country named Johor that have a gold mine in a district called Segamat. The villagers always busy with their gold mining activities.

Even though the activity was conducted by the villagers, but they were not allowed to use any modern machine to do the mining. All they can do is only a traditional way and it takes a lots of work to get the gold.

I wondering if they can use sieves to separate the unwanted things... definitely they can save their time and energy.

Well, sometimes life can be simple for certain people.. but sometimes not. Agree?
