| Show JENNINGS ON NEVADA DOUGLAS Engineer Submits An Interesting Report to Manager of Ne No Nevada Nevada Novada vada Property REFERS TO THE LUDWIG MINE Condition ls is lq An Splendid from Work ork Planned E 11 p r Jennings of the engineering staff of the Nevoda Douglas Copper company who returned from a trip to 10 the tho properties of the tho last lost named cor corporation a a few days ago ngo has haR submit submitted ted led lila his report to the manager Walter Valter WalterC C C Orem Orom and 11 In It ho describes the tha work dono and developments made mado In inthe the tho Novada Douglas and LudwIg mines since his reports which calc out In December of or last year and In February of bI this year Tho The oro or bodies of tho the Doug Douglas 10 las IllS says sa Mr Jennings occur in three separate areas atens or garnet garet rock thu largest being that known an IU the Douglas Hill 11 The Tho ho second body bod Is la southeast of or Douglas Kill 11 and the tho third body bod extends from Douglas lull Hill Hi south southwesterly westerly for tor 2000 feet For POl tho tim purpose of ot developing this latter body bod together with the tho Douglas Hill Hl area a working tunnel 6 by 7 feet teet In cross cros section was started stared at nt the tho southwestern edge of tho the third ore body boll boI last ye yea and has han been advanced In the direction of Douglas

shallow pits for a n distance of feet teet An Another Another other othel ore ole body has been heen traced and partly developed by shallow workings that has a 1 northeasterly direction and following a 1 contact for 1000 feet This body Is 18 being de do developed eloped by b n a drift beginning near the In the 40 foot crosscut Theo arc the tile most Important work now being h done as they will wi place a large amount or of o ore In Right night Tho The width of these ore bodies Is 18 from to OO feet anil the tIme garnet between them will 1 un undoubtedly undoubtedly contain a n low grade

tho the property Referring to the lie Ludwig property Mr lr Jennings declares the th condition of ho tho property Is very er satisfactory and recent developments there tere have been unexpected He lie 10 adds that it Is in II Im Impossible impossIble possible to predict the size Ilze ot of the tho sul sui oro ore body bOIly but hut judging from tho thio length of ot the outcrop It will wi probably bo be jo nt at least COO feet teet long and from 20 o I to 10 o 60 CO feet In width Mr Jennings be bu believes lel lev n In the bottom of the Ludwig to tobe tolIe tobe be lIe a 1 good place to drive

conclusion to change my m opinion as to ho tho amount or alue of the tho ore In the th Nevada Douglas mine the work vork aa as tar far faras taras as lS It has hal been done lone Is satisfactory In Inthe Inthe inthe the amount and ami quality of ot the tho th ore oro oo dis disclosed disclosed closed and If it It Is II continued as ns now planned the amount or of ore oro In sight eight dx six
