Show MOIIIAIBIMJIIJ MAKES A FIIIE SUB Supt. J. Benton Leggat of the Montana Mon-tana Bingham, who has been looking after operations reports that he is getting the work well under way and expects to show results within a reasonable reas-onable time. For the nine months ending September 30 the shipments of ore aggregated $26,936, according to a recent official report. Mr. Leggat recently made a report on the property. The main tunne' is iMQ feet to the Mayflower vein. Trlfts were sent south and some lead silver or encountered about 800 feet southwesterly south-westerly from the main transportation transporta-tion tunnel. " The main body under the Fortuna workings is expected to be cut iu about 300 feet, or 1700 fe.t southerly from the main tunnel. The No. 2 crosscut has 130 feet to go to fhe Fortuna vein, and there is s'rong possibility of developing a good grade of ore In this sec Ion of the Fortuna vein, as indicated in the Fortuna mine workings above, the report says. "The mill, which was erected in 1917, was operated several months by the company at a loss, and finally closed down in March, 1918. The construction con-struction and equipment of the mill were found to be faulty, and the percentage per-centage of recovery of values was very low," the report declares in part. "The recent development work in the Fortuna mine consists of certain crosscuts and drifts run on the copper cop-per ore body in the Mayflower vein to determine the width and extent of said ore at certain points, which have proved up even a larger tonnage of milling grade ore than was formerly form-erly estimated. Also a drift and raise has been driven on the Fortuna vein, developing the existence of a body of good milling ore, with some shipping grade, in what was undevel- oped territory on tnis vein. "This particular development is important, as it is in virgin territory and over 500 feet south of any workings work-ings on this Fortuna vein, and would Indicate a similar body of copper ore as that developed on the iMayflowur vein in this section of the mine to the east. This will add a large tonnage ton-nage to the known ore bodies in the Fortuna mine, which was the basis of former estimates. "I am confident that with intelligent intelli-gent development, good mining practice prac-tice and economical business management man-agement that a larger tonnage of shipping ship-ping ore can be mined from both the iMayflower and Fortuna veins, and a substantial profit made over and above the current expense of mining operations. "When these Fortuna m'ne ore bodies bod-ies are proven at the transportation tunnel horizon, which will give, from engineer's estimates, over 3,000,000 tons of ore, these veins or ore bodies can be developed through the Mascot tunnel of the Ohio Copper, to an additional ad-ditional depth of 550 feet vertically, or on the dip of the veins of approximately approx-imately 1700 feet. Tills would add millions mil-lions of tons of ore to the Montana-Blngham Montana-Blngham ore reserves available for transportation through the Mascot tunnel. This tunnel crosses vertically vertical-ly below the main copper ore body In the Fortuna mine, in an easterly and westerly course, it connects the Ooio Copper ground and shaft to the west of the Fortuna group with the Ohio mill at Lark, a distance of about three miles. The Ohio ore, as well as Bingham Bing-ham Mines, is all transported through this tunnel by an electric tram system sys-tem st low cost for transportation." |
