Ruby Hill Mine

The  is located just off the path to Jacobstown, in the Northwest corner of the map. Mojave Wasteland.

Layout
The main room of the mine features several Lakelurks. Going up the stairs and down the path that follows leads to a large water-filled cavern, with more Lakelurks.

 * Pushy can be found on a dead Jackal Gang member in the big hall with a lake.
 * A key can be found on the dead Jackal Gang member that opens a locked explosives crate.
 * Multiplas rifle (see easter egg section below)

Easter egg
At the back of the cave there is small lake with an island in the middle. There are three explosives crates on this island. Walking across the plank onto the island, pass the crates to the left and walk off the back of the island into the water. Dive under water to find a round table with four chairs, four human skeletons in or near a chair, and the corpse of a Super Mutant Brute. On the table is a deck of cards with two cards dealt in front of each seat, 1 up and 1 down, as if the four skeletons had been engaged in a card game, maybe blackjack, when they died. There doesn't seem to be any items for pick-up laying about, but you can search the super mutant for a significant item pick-up including a Multiplas rifle.
