Show Exploration in Deep Levels Leves In n Older Zones loses Promising Future of Tintic District Is Discussed in Book Issued by Geological al Survey WHAT HAT the future holds for the Tintic district as a whole is discussed dis dis- dis- dis V V cussed as follows in the book recently issued by the United I States geological survey and entitled Geology and Ore are Deposits of the tile Tintic Mining District Utah I. I I Prospecting and development at Tintic have always been difficult and extensive for tor the ore Is confined to certain zones I of ot deposition separated by long stretches of ot barren ground and in each zone the theore theore theore ore bodies may be disposed without much regularity or continuity The latest great developments have been In the theIron theIron theIron Iron Blossom zone and at present the themore themore themore more important explorations are being directed northward from the Gemini and Chief mines All the valuable ore zones zone between the thO Gemini a and the Iron Blossom have I I ol IYa probably O IY been discovered West of the Gemini zone there is little encouragement encouragement encourage encourage- ment the unfavorable formations soon giving place to the still more unfavorable quartzite The character of ot tion lion shown at a few tew places In the workIngs workIngs work- work Ings logs of this area indicate that the solutions lions were weak weal
