There is no MIFARE Ultralight 1K. Perhaps you mean MIFARE Classic 1K? — NFC guy

The card seems to me like MIFARE Classic 1K.

I think you have mistake in the key number that you are tying to authenticate with. Try this:

ff 82 00 01 06 FF FF FF FF FF FF  //Set key with on slot 1
ff 88 00 01 60 01                 //Auth with key from slot 1 to block 1

I hope this will help.
