85 EXTENSION IS MAKING GOOD
 SHOWING

Probably no othe: company ever operating ill the ,ocal mining district has n.f tie ds encou gin. progress in Extension Copper Company, which began work at the Atwood mine two weeks ago. This property has been gotten into shape for systematic mining and already a high grade ore body has been opened up and ore broken down ready for shipment.
 The S5 Extension Copper Company came into the district upon the rec ommendation of l.. D. Mcclure it's manager, and Franklin B. Smith it's consulting engineer and geologist. Beside taking over a large number of undeveloped mining claims ad- joining and near the S5 Mining company property the new operators took under bond the Atwood mine be- ginning work on that property at once. MT. Mcclure made a careful examination of all the stopes and levels and believed pay ore could be mined in one of the stopes on the 148 1 foot level. He put force of men to work there and has made one of the most encouraging discoveries of high grade shipping ore ever found in the Atwood mine. The ore will average s per cent copper with a tlne gold and silver content. It should net $50 per ton or $2000 per carload at the shelter where it is in demand for the high grade silicious value Over three carloads are now broken in the stope pending the unwatering of the 120 level from which place it will be hoisted.
 An electric pump is installed in the 210 stump and a torpedo-bucket will aid in the unwatering this week. As soon as the level is cleaned up. the ore will be taken from the chute.
 Beside the work in the 14S foot level stope the S5 Extension Copper company is prosecuting development work on the 110 foot level and doing some open-cut work. At all places they are making an excellent showing and the mine gives all evidence of soon becoming one of the camps big producers.
 All the equipment at the Atwood is in excellent condition. The company plans to soon install an air compress sor and drills and replace coal with an oil burner in the boilers.
 The S5 Extension Copper Company is proceeding with it's work in an efficient manner and is fortunate in getting into a fine body of shipping ore from the start. All indications point to unprecedented success for the new operators.
 The Atwood mine is well situated in the district for ore occurrence. Three of the claims, the Bessie, Henry | Clay and Atwood are located on one of the larger dykes which outcron | prominently throughout the district. This dyke passes from the north side-!ine of the Henry Clay about six hundred feet from the west end of the | claim and enters the Three Heroes Il group On the Atwood therc are three veins along the dyke which may
 be traced a distance of about six hundred feet The dyke is 75 feet Il wide along the main outcrop. The
 main shaft on the Atwood claim is
 800 feet from the east end line. Ii
 is vertical to a depth of 318 feet.
 Levels have been cut at depths of 75
 14S, 210 and BIO. The principa
 development has been done on the 21O level. Beside this work there are
 a large number of large open cuts II and shallow shafts showing ore ir
 place. In the upper levels much oi the vein material shows distinct E teaching. This is most favorable foI : high grade ore occurrence with depth E With proper development work the r Atwood is certain to become one of the camps biggest and best proposi tions.
 On Wednesday of this week a rep resentative of the Western Liberal went over the Atwood and found all
 statements to be exactly as repre- sented by the operators last week.
 There is much ore broken and in every way the mine is looking good
