Yery rich, but not yet opened. (d. ) Southern Light Ledge. Just opened to a depth of 100 feet. Pay streak 15 inches. Six men take out 2 tons of rich ore daily. Old System, Class II. The number of feet on each ledge is: North Star, 1, 000; Oregon, 1, 000 ; Blue Ledge, 800 ; Southern Light, 900. They are parallel, and sufficiently near each other to be embraced in one comprehensive system of workings. The present shafts and workings, although they have already yielded handsome returns, are to be ...considered rather as pros- specting work than as the proper foundation of systematic and permanent operations. In order to complete our view of the present condition of the property, however, before proceeding to indicate its capacity of future development, we adduce a few statistics from the books of the old Oregon Mill and Mining Company. The mines have thus far furnished, on an average, 7 tons of ore daily, yielding 200 gross returns per ton. The cost of mining and smelting is estimated at $40 per ton.
