Go down to Kakariko Village, you can buy a replacement shield there for 50 rupees. Alternatively, you can just go through the mines without it (I did after mine burnt up) then leave Kakariko after being warped back there. You'll get a letter saying that there's something exclusive in a shop in Kakariko. Turn back and find the shop, you'll find a Hylian shield there for 200 rupees.
