| Show jackrabbit JACK RABBIT DISTRICT prospering in an article on the old jackrabbit Jack rabbit district out of pioche nevada the record of that place says the old day mine acquired by the black metal mines inc in march 1919 1619 from the uvada copper mining company after negotiations extending over a period of about a year is now producing seventy five tons of iron manganese fluxing flexing ore carrying an average of between twelve and fifteen ounces of silver to the ton the last settlement sheet from the american smelting smelling Sm elting and refining company demonstrated the fine profit derived from this ore four cars brought a net smelter return of the analysis showing 52 per cean of combined iron manganese and lime with but 14 per cent of insoluble content the silver content averaged ounces and the treatment charge was the ore being shipped on a favorable long term contract new equipment the new equipment recently installed at the mine which consisted of a sixty horse power fairbanks morse gasoline engine and a 32 5 cubic foot sullivan air compressor is now responding splendidly and enabling the management with a reasonable sized crew to easily maintain the expected increased tonnage new equipment to more economically bring the ore out of the shaft loading pockets is now in operation and a long train of up to date one ton cars is being hauled out by horses quickly and cheaply ore is being mined on four principal levels in the mine and every face shows an improved grade with development work there is a larger tonnage of ore in sight than at any time in the old mines previous productive history the bulk of the iron fluxing flexing ore is coming from the and levels and a smaller tonnage from the level on the level intelligent study and mapping of the geological conditions revealed the possibility lity of the extension of the bedding planes from the enriched area adjacent to the old level bonanza through which the shaft passed to connect with the main day tunnel and prosecution of the development plan soon demonstrated a large body of good ore in this section of the mine on the level on the level a twelve toot foot bed of ore has been opened up carrying an average of over twelve ounces in silver with enriched areas this ore made off from the old mill hole which produced in its ramifications ficat ions a large tonnage of silver lead carbonate ore and it is from this same mill hole that these lower grade beds of silver iron manganese ore connect correlative to the strong cross fissure and mineral bearing channels at the present time a raise is being run to connect up with this newly developed ore bedding which is bearing off to the east and daily adding to the ore contained in territory of this portion of the mine on the level a favorable showing of silver copper ore is being developed close to what is known as the may day fissure A carload of this ore assaying an average of twenty five ounces in silver with 4 per cent copper per ton is expected to be marketed shortly visitors to the mine who are familiar with this grand old producer return enthusiastic as to its present condition and the heavy movement of ore over the pioche pacific railroad is the best justification of their optimistic views the ida may mine to the north of the jackrabbit Jack rabbit territory lies the ida may mine owned by the E and F mining company and which is at present under lease to arthur murphy this property is a steady shipper of silver copper ore over tons having been dispatched to the smelters shelters sm elters during the last six months the ore which is being followed in miner like fashion by an incline shaft occurs along the intersections of fissures in the limestone and makes back from these fissures into the permeable lime beds the lower ore bodies at present being mined below the old tunnel level are similar in metal content and grade to the bodies shipped from the upper levels of the mine recent assays essays from the ore as exposed in the lowest workings give from six to fifteen ounces in silver and 8 per cent copper plans are at present under consideration to install the recently purchased equipment and thus insure more economical handling of the ore and promote the development of the property to a greater depth activity in bristol increased activity is now evident in the bristol district tributary to jackrabbit Jack rabbit an increased tonnage of copper silver ore being daily received at the terminal bins at jackrabbit Jack rabbit this ore is being mainly produced by leasers leaders from the dumps and superficial workings of the old bristol mines and when plans at present being considered fully mature a still greater tonnage will be mined from the lower workings which are far from being worked out the jackrabbit Jack rabbit district is at the present time certainly responding well to intelligent development work and encouraged by good metal prices should continue and correspondingly spon increase its already substantial shipments of ore to the salt lake smelters shelters sm elters |
