SHANNON COPPER.
An Expert Reports on the Property
 Status of UndererOund Reserves.

Boston-R B. Watson, the mining
 engineer of the Shannon Copper Co
 in charge of the mining operation.
 of that company. furnishes President
 George C. Gill the following report
 of mining developments:
 After q careful inspection of the
 mine recently, I am glad to state
 that the development of the last few
 months has shown some very satiS-
 factory results.
 West Ore Body: The most import ant is the proving up of the West ore Body. This name has been given to the ore body lying along the north and south Assure which outcrOps on the Shannon claim in the Green open cut and dips west into the Black Hawk claim. On the Boulder level it makes the No Boulder stOpc; and on the Ore level it makes the No. , Black Hawk and Native Copper stopes.
 Recent work on the Harrison level and raises from one level to another nave utHlDINli dltAl that llit h'Shit ' lo continuou, from the surface to the Ore level: and while there are barren areas along the Assure, the good re- suits already obtained prove this fracture to be of great importance and shows the advisability of pros pcctiug it all over the mine.
 The old No. Boulder stopc on the north side of the double track tunnel was only three sets wide: the new stopc on the south side is 10 feet wide and has reached q length of 90 feet, with the Assure and the ore badly still strong in the south end. There are no developments south of here in the Boulder level and COnsd- ering the long ore body on the Harri- son below, the outlook for the Boulder is very favorable.
 On the Harrison level the Assure has been driven on for 42J feet, show ing q streak of high grade ore the entire distance: the drift is still go- ing north, recent samples of the breast asSaying over 20 per cent. cop per.
 Three crosscuts from this drift show good width of concentrating ore lying west of the high grade streak. The south CrossCut assays 90 per cent. for 65 feet: the middle one 90 per cent. for 40 feet, and the north croSScut l5 feet of ore
 
 A winze recently sunk on the Assure shows good ore to within p feet of the Ore level. This is bv far the longest continuous ore body yet opened up in the mine; preparations are being made to start stope on it at the bottom of the ore.
 No. 2 Black Hawk stopc is on the south end of the Assure; on the sill floor the stopc is l95 feet long with the south face still in good ore.
 Recent development on the east side of No. , Black Hawk stope has opened up d body of ore 20 feet long. The stopc on the west side of the main stope continues to run south in ore.
 This gives us three parallel ore bodies separated by low grade ma terial on the sill floor. but which will no doubt run together above. making one great ore body l50 feet wide and more than POO feet long.
 East Ore Body: When the east ore body. Stopc No. 569, was opened up | on the Ore level, it was supposed to | be the continuation of the same shoot l of ore that was taken out on the ! Boulder level. But after further 1 it has been found that on the Harrison level there are really | two ore bodies and stope No. 569 is 1 on the west side. A raise now being | put through from the Harrison indi- CatcS that this west side stope will 1 connect with the No. shannon stope | on the east side is the downward cX- tension of the East Ore Body on the Boulder level. This has not been stopped on below the Boulder. On the Harrison level it has been opened up | for 300 feet in length and two cross | cuts show D to 40 feet of ore. One | winzc went through the ore at 20 feet, another still going down has ore | for 56 feet below the Harrison level. | X Stopc will be started on this ore | body as near as possible to the Ore | level.
