This is exactly what this is all about. Rewarding their time and efforts, without them expecting to be paid.

[AskSN] How much would you offer volunteers??

If they are volunteering, they are probably already happy to contribute to the project as they can. In the other side, you cannot expect much as if they were employees. 

However, a nice thank you gift, a warm way to recognize their efforts and provide rewards every times they accomplish something is probably a better way to have them   more motivated to pursuit volunteering.
