Show ID Gold Dusi Mine finds a Big Reef Ten-Stamp Mill to Be Enlarge to fl Two Hundred Tons Daily Capacity. Epecial to The Tribune. SALMON, Ida"., Jan. 13. The Gold Dust LLt mine, in Ixcsburg camp, twelve miles from this place, has developed Into a bit; reef proposition. A SaIL Lake cim-Iany cim-Iany has been developing one of the Old-est Old-est prospects In the Stats In a desultory v ay for two years, but tho nature of frold-btarlnn formation was not fully ... monstratod until recant analysis rc-sealed rc-sealed tho fact that what was supposed CO be a (tranltn country rock proved to lie an auriferous conclcimerate with work-able work-able values In very largo tones. The Gold Dust lead was considered the mother lodo of thu Leesburg placer IkmIs by the pioneers, and wus ilrst located In i he 'COs. Persistent exploration wns car-rled car-rled on, with tho main object of rovi il-lug il-lug a vein of quart?, that had enriched IHBB Ward's gulch by the process of erosion. Some of the richest ground that ever was v. orked for placer gold was found Just below this mother lode. Ono whole- claim "turned to tho liffes of the owner In IW $1000 for every square foot of surface. sur-face. Of course, this w:is a small claim. The, streaks of pay were followed hv Irlfis to tho apex of this mother li !. Bui those pioneers were not familiar with It ef formations.

Their energy was devoted to tho bid prejudice that ledge rold must bo In a regulation Blllcioue formation. The Gold Dust company nn a rr-vs-in to n contact Where this had was supposed sup-posed to be concealed by a deep (rranite deposit of waste. At this point tho reef formation chanced to lx tUtcd and in contact with an altered fiuartzlto formation forma-tion that had also been fiat at one time. The Quartz lead was not found, but the prominent evidences of values caused tests to be made which revealed re-vealed good gold values MOT the contact. A ten-stamp mill was installed to work what was supposed to bo a vein of a few feet In width. The p ly zone' was traced to wider and wider limits, until the country ruck was all classed as val-I val-I ible ore. The little mill was a plaything play-thing In comparison to the demands of the proiierty. It has aNo been demon-strntfd demon-strntfd thrit the nr.- renins ;i eviinlde treatment.
