# Mines

Mines play a crucial role in the game. By finding a Mine, Explorers are entitled to a Mine Owner Fee paid in WAX after their Mines are fully depleted. First, the Mine has to be opened through a Mine Opening Raffle.

Mines can be found by Explorers during explorations and they charge the Zombie Miners to let them enter in their mines.

There are 6 types of mines:

1. **Small Mine (old version)**: has a capacity of 1000 mining tasks. Grants the Mine Owner a 1-time fee of 40 USD (paid in WAX)
2. **Small mine (new version)**: has a capacity of 500 mining tasks. Grants the Mine Owner a 1-time  fee of 20 USD (paid in WAX)
3. **Medium mine (old version)**: has a capacity of 2500 mining tasks. Grants the Mine Owner a 1-time fee of 200 USD (paid in WAX)
4. **Medium Mine (new version)**: has a capacity of 1500 mining tasks. Grants the Mine Owner a 1-time fee of 120 USD (paid in WAX)
5. **Big Mine (old version)**: has a capacity of 7500 mining tasks. Grants the Mine Owner a 1-time fee of 700 USD (paid in WAX)
6. **Big mine (new version)**: has a capacity of 3000 mining tasks. Grants the Mine Owner a 1-time  fee of 280 USD (paid in WAX)

Once the mine is fully depleted, the Mine Owner receives a trade offer of his depleted Mine for a Mine Owner Certificate. After accepting the trade offer, the Mine Owner will receive the Mine Owner Fee. The Mine Owner Certificate can be used to craft a Mystical Tablet that can be staked to earn ZBC passively.

PS: The trade offer comes from the account **zombielandsc** or **fd3u.wam**<br>

The Mine Owner Fee is converted to WAX considering an average WAX:USD ratio (considering the close ratio daily) from the day the Mine was opened to the day it depletes.
