But a few months have elapsed since the discovery of the X ray, and layer men are now prepared to accept almost any claim that a scientist may choose to make, but expert chemists and metallurgists seem inclined to deride the Emmens proposition. Two old Utah mining districts that have made great strides during the present season are TIntic and Marys-val- e. Many old abandoned properties in the former district are receiving intelligent and vigorous development, and the number of shipping mines steadily increases. In the Marysvale region the production has been of little importance, but more development work has been performed than for several years past, and extensive prospecting has resulted in several important discoveries. The results of the seasons operations In these districts, the opening up of the new and rich State Line district and the progress made in the development of the Camp Floyd gold field fulfill the predictions made early in the year that this season would be one of importance to the mining Interests of the State. There are other sections concerning which considerable ado has been made, but in which developments thus far have not revealed any great merit. The old districts of Park City and Bingham are producing steadily, and more properties have been operated than during recent years. After the Presidential election, no matter how it results, money will circulate more freely, mining investments will increase and silver and lead will command better prices than now prevail. Inexperienced prospectors and mine-owne-rs sometimes make serious mistakes concerning the actual market value of their ore, and these mistakes occasionally lead to the development of property from which they are never able to extract a pound of shipping ore. There is a vast difference between the assay value and the market value of ore, as every ore producer well knows, but which some owners of prospects do not seem to know. One day this week a Salt Lake man was complaining bitterly because a shipment he had recently made just paid freight and treatment charges and left him nothing, although the assay value of the ore was much above the cost, and he had expended nearly $5000 in developing the property. By way of illustration we will take an ore that assays, say, 10 ounces silver, 30 per cent lead and half an ounce of gold per ton. The silver would be worth $6.60, the lead $15 and the gold $10.33, a total assay value of $31.93. Suppose the cost of mining was $3, freight $8 and treatment $10, a total of $21. This is $10 below the assay value of the ore, and, strange as It may seem, there are prospectors and others interested in |
