V Lambourne who wh received his training under John J J. J Daly a pioneer Park City operator became convinced as a result of a study of the district that the east side had as great possibilities as the west So more than a score of years ago Mr Lambourne quietly began to buy pr properties in the eastern section George D. D Blood another of Park City's most capable operators had also formed the same theories concerning concerning concerning con con- the east side aide agreeing with those those those-of of Mr Lambourne As a result re re- re- re sult suit the holdings of the two men were merged other calms acquired the Park Utah Mining company organized organized organized or or- and financed by Mr Lambourne Lam Lam- bourne Preliminary surface work was begun In 1917 and actual exploration exploration exploration started under the direction of Mr Blood in January Januar 1918 In spite of the many discouragements discourage discourage- ments meats under ulder which operations were conducted the conducted the difficulty of securing I adequate labor and funds in wartimes wartimes war war- times and of exploring at great ex ex- ex- ex pense a formation about which little was known the known the work was carried on daunt essly Three years later almost to the week the great ore body began to appear In the face of 4 15 drift COMPARISON l MADE B.

hoisted feet to the Ontario No 1 tunnel out of which It is two and a halt bait miles to the Ontario loading station at Park City All Allore ore supply and passenger trains are by electric locomotives By lIy hauling to the Daly West Wed shaft the twelve mile wagon haul to Heber is eliminated and the cost reduced from a tun ton to 1175 After the first of the year Superintendent Super Hunt plans to 10 Increase pro Iro- production to a n total ranging from 10 BOO to 1000 1 tons tone can be he handled bandied or tOts torn can be handled through the West Daly shaft the overflow will probably be
