The Boss tin mine is about 1 1/2 miles northeast of Gaffney, on the northwest side of a small hollow that drains northeastward into a tributary of Providence Branch. The work consists %of many open cuts and placer washings, pits, and trenches, and a shaft more than 130 feet deep, with levels, all within a space about 600 feet long from northeast to southwest and 100 feet wide. Placer mining has been done on the lower part of the slope, where water was avail- able, and material obtained above this place has been carted down to the sluice boxes. In this way the greater part of the hill slope from a point near the shaft northeastward to the branch, a distance of about 400 feet, has been worked over.The shaft and underground workings were not accessible at the time of visit, but portions of the vein were exposed in shallow workings, and these, with descriptions by Sloan and Graton, furnish material for the notes here given. A crosscut was driven from the shaft northwest to the vein on the 63-foot level, and "winzes were sunk on the vein from this level to the 90-foot level and there con- nected by a drift. The shaft cuts the vein at a depth of nearly 100 feet.
