Tanren Mines

Tanren Mines (Mines, TM) is a mainly Rock-, Ground-, and Poison-type dungeon in Tanren, found north of the road fork south of Tanren City. The dungeon has 28 Floors, and supplies. You can continue onto Tanren Mines Depths optionally, with a Pokémon that can learn or has Rock Climb. Starting on Floor 23, Hippowdon can spawn so sandstorms may appear due to its Ability Sand Stream.

Boss
A Nidoking and Nidoqueen are found after the last floor of Tanren Mines. The two Pokémon try to break down a wall, but then, they quickly mistake the player as an enemy and attack. After defeat, Nidoking apologizes to Nidoqueen for failing, but then they realize that the player is friendly after Nidoqueen points out how blind they were, and Nidoking and Nidoqueen ask the player to rescue some miners while Nidoking explains about the monster that Nidoking and Nidoqueen mistook the player for. Nidoqueen praises the player before a pathway is revealed. Nidoqueen wishes the player good luck before walking off with Nidoking.

They know the following moves:
 * Nidoking: Earthpower, Fire Blast, Sludge Bomb, Thunderbolt
 * Nidoqueen: Bulldoze, Helping Hand, Toxic, Venoshock

Boss drop:

There are several quicksand warps further in the same room. The correct warp is the smallest sand pool in the top-left section. You'll be warped into a room containing a single Rock Climb HM, Kangaskhan Storage statue and Chimecho Assembly post. Going into the wall on the right leads you to Arid Cavern.

Arid Cavern
The Arid Cavern is a puzzle where the objective is to get through the map using the newly obtained Rock Climb, going through various sand pool warps. At the start of the map is a warp that exits to Tanren City Plaza. Completing the puzzle successfully gets you to the entrance to Tanren Mines Depths.

Secret Room
Tanren Mines has Secret Rooms starting on Floor 15. There's two Deluxe Boxes in them.

Dungeon Objective
This dungeon offers HM Rock Climb after the boss, giving access to various new dungeons and locations. Players commonly run Tanren Mines for Poké, because of the amount of Diamonds you can find, or to get to Tanren Mines Depths.

Tips

 * Do not complete missions from this dungeon if you wish to visit Tanren Mines Depths. This is because the dungeon completion sound effect plays after leaving the boss room, teleporting you back to the mission board in Grassroot Town if you have a mission completed.

Trivia

 * On March 25 of 2019, Tanren Mines was split into another dungeon; Tanren Mines Depths. It was created so players could use HM Rock Climb right after obtaining it, rather than doing all 42 Floors it had been.
 * This dungeon was one of the first to featured on the official PMU Tumblr page.
 * The Quarry is similar to the "Lost Woods" from the Legend of Zelda series.
 * When this dungeon was released the location of the correct warp changed every few days.
 * In the player house "Gaia", players can find what appears to be an early sketch for the mines' outer entrance.
