Show 0 importance OF THE BLIND LEDGE it is generally the rule that the average prospector following up the float scattered along the mountain side is always looka looking ing for its source expecting invariably to find that it has broken away from an aute oute outcrop ping ledge further up toward the crest of the th e range it nearly always transpires that the ledge is found and that it forms the dincov ery point for a location and it I 1 is S here generally that the first development work is done and it is from such discoveries that many producing and dividend payi paying ng mines are added to the splendid string of wealth producers with which so many of the mn ing camps of the west are endowed it often happens however that with the development of such discoveries in the running of cross cuts in the making of up raises and in the sinking of dinzes blind ledges are found which in many instances carry higher values are larger in pont point of size and which are stronger and more permanent than were the outcropping out cropping ledges upon which the first locations were made As a matter of fact so many valuable discoveries of this character have been bee made in a number of our mining camps of late that the mining review feels impelled to call attention to their value and importance and to the further fact that mine owners in the operation and development of their properties should pay more attention to the many hints so often thrown out by dame nature to the signs in the rocks as to the probable existence of deposits of the precious metals heretofore unsuspected oxidized spots and patches on the walls or of the vein should be investigated and promising stringers should be followed as they often lead to the main ore body of the mine former operations having been confined to nothing more than an offshoot off shoot of the lode or a smaller parallel deposit and this supposition is reasonable as it is often the case that the main ledge has been eroded at the surface to be covered later on with debris or in its origin it may not have reached the surface at all it is also often the case that what was at first supposed to be the wall ot of the vein is merely a false wall beyond which exists the richest and largest ore deposits in the mine in many cases the life and value of a mine is not confined to a single ledger ledge as it has often been found by thorough investigation ti that the boundary lines line s of mining properties embrace parallel veins loaded with immense deposits of high grade and low grade ore the existence of which were W ere not even dreamed of before by experts and mining operators the history of mieng in the east is replete with instances of this character and recent discoveries ln in this lin hnz should encourage the search fr for the the hidden vein kor for the blind ledge |
