Triggs Mine
On the same belt as the Stella, with similar formation and ore bodies, is the Triggs mine, situated east of Witch bay on a fairly good wagon road about 2 mile in length extending from a small lake which is crossed by canoe shortly Triggs Mining Company after leaving the landing at Witch bay. The property consists of three locations, McA56, 129 and 148, aggregating 113 acres. It is owned and operated by the Triggs Gold Mining Company of Ontario, Limited. President, F.D. Sargeant, St. Paul. Minn.; vice-president J.W. Millar, Rat Portage; secretary and treasurer, J.H. Triggs, Rat Portage. I visited the place in August. Work has been going on since October, 1897, under the management of J.H. Triggs, secretary of the company. The workings are confined to an elevated portion of ground 40 to 50 feet in height, about 150 feet in width and from 700 to 800 feet in length, surrounded by low, swampy ground. The formation is fine grained trap. The richest ore is confined to veins, and consists of zones of quartz and greenstone mixed, extending along the top of the hill with a strike of nearly east and west. There are two of these veins, one on the north and the other on the south side of the hill, about 150 feet apart: but the manager has made The other 6 repeated tests, resulting in the conclusion that gold is contained to a sufficient extent and sufficiently diffused to warrant treatment of the whole mass between the veins. the quartz in the veins assays exceptionally high, and the greenstone between gives promising returns.
No. 1 vein, on the south side, has been exposed by a number of small test pits two or three feet in depth, sunk at frequent intervals, extending over a distance of several hundred feet. Oxidized material is revealed in most cases, with from a few inches to two feet of quartz. A shaft has been sunk on the vein to a depth of 80 feet, but was not in operation and was partially full of water at the time of my visit, preventing ingress. At a depth of 40 feet a drift has been driven eight feet west along the vein. Mr. Triggs informed me that the shaft followed a very rich pay streak for the greater part of the distance, but this dipped so flatly near the bottom that sinking was continued in the foot “wall. Several hundred tons of rich ore have been dumped separately at the surface, awaiting the erection of a mill. A neat collar and a ladderway have been provided, and a temporary shaft house built. On No. 2 vein, which is traceable for 500 to 800 feet along the northside of the hill, two test pits have been sunk: one 10 feet deep revealed four feet of vein matter consisting of quartz and “greenstone, charged with pyrites and said to assay well. The other,70 or 80 feet west, was six feet in depth and 14 feet in length, exposing about 10 feet of vein matter; the vein branched aggregating about five feet in width. Iron and copper pyrites were abundant and assays w. re satisfactory. Near the foot of the hill, on the north side, a tunnel was commenced which was in tended to be dr. ven through to the south side, cutting both veins. I learned later from Mr. Triggs that this had been driven 40 feet, and work at the mine suspended, with the intention of commencing again during the winter. The force consisted of three miners and a cook. Boarding camps, a stable and a black smith shop had been built.
The Triggs mine closed down on July 14, owing to lack of capital for further development work. One hundred tons of the low grade ore have been brought in for treatment at the Keewatin Reduction Works, and if ^2.50 per ton, or more, is obtained, the result will be considered satisfactory. Mr. Triggs has hopes in the event of such being the case, of being able to obtain sufficient capital for the further necessary development of the mine by the sale of treasury stock. The capital of the company is $500,000, divided into 100,000 shares wit a par value of each. Twenty thousand shares are in the treasury, and these cannot be sold at less than par value. Mr. Triggs gave me the following underground measurements since the closing down of the mine: Main shaft; depth 225 feet, First level: depth, 108 feet. No. 1 crosscut, driven northwest from shaft, 58 feet. Drifting in crosscut at distance of 51 feet from shaft; length 206 feet; direction, west. Drifting from about same point in crosscut, in same drift, at a distance of 186 feet from No. 1 crosscut; length, 58 feet; direction, southeast; driven towards air shaft, which is 242 feet from the main shaft, and 61 feet deep, vertical dip. A crosscut has also been driven 19 1/2 feet northwest from the same drift at a distance of 51 feet from No.1 crosscut. Second level: depth, 208 feet: crosscut, northwest from shaft, 29 1/2 feet, Drifting from end of crosscut, 59 feet west and 50 feet east. Total length or amount of development work on property, 826 feet. Other shafts have been mentioned in previous reports of the Bureau.
