The seed works in the newest minecraft snapshot 18w16a. It has a huge mineshaft in the mountains. Its very visible from outside. Its has two chests full with lots of iron and lapis. Inside the mineshaft there is a zombie spawner with chest that has a golden apple. It can be very good for building or just messing with it. i dont know If it works on other versions of minecraft.
