For those having trouble with this, this tip is from Microsoft Solitaire Collection's Facebook page:
"Some of our fans were wondering how to get the Mining for Gold achievement. As you can see in this video, the easiest way to play with one card (instead of 3 card) Klondike. Use only the cards from the deck that you need to reveal the rest of the face-down cards on the board. Above all else, make sure you have at least 5 cards in your deck unplayed. Once you have it set, go to the very end of the deck and work backwards. After you've played 5 cards in a row from your deck, you'll get the Mining for Gold Achievement."
Now in summary, make sure all the cards on the board are flipped using as few cards from the deck as possible. Once you have 5 or more cards left and all other cards flipped over, just start putting cards to the foundation! If it doesn't work out, remember where you get stuck and use undo.
Here is the video that they used to demonstrate their method (All credit to Microsoft Solitaire Collection):
