Smith Mica Mine 1904 - Silver Queen Mine - 1910
In 1906, the Dominion Development, and Improvement Company had rather named this project the Smith Mine. It was originally opened up for apatite, but when a pit was sunk to a depth of 25 feet on the vein, Mica crystals were uncovered throughout the Apatite. Much of the apatite is rather soft, and granular, in which had given the mica a favorable matrix, and had crystallized freely. According to reports the vein in some place was up to 10 feet wide, consisting of apatite, calcite, and mica. It was also reported that the dip has an angle of 050 degrees to the horizontal. On the side of the vein is a mica pyroxene schist, and was a few feet in thickness, in which turn, cuts through the granite gneiss. A belt of mica pyroxene schist was also traced for some distance along the surface, where at different places a little mica had been taken out. Other associations with the pyroxene rock and the mica veins are also marked over the whole mica area.
Production during 1907, was mainly aimed at mining the mica, and apatite as the mine was still being worked by the Dominion Development, and Improvement Company. As mining continued during 1907, a pit was further extended to a depth of 65 feet as it was aimed at following the mica. The first 25 feet of the pit was considered to have been vertical, from which point has a dip to the west at 045 degrees. At the time, no uniform system of development was followed, in which the mica had occurred through the apatite and calcite so irregularly that the workings had merely followed the pockets.Much of the workings at the bottom of this pit had rather measured 25 feet in length by 12 feet in width.It was also at about 50 feet from the surface where the mica was being followed to the north at a distance of 30 feet from the main pit. Power at the time was rather being supplied by a boiler that had operated the drills, and hoisting system.
As mining operations became ceased by the Dominion Development, and Improvement Company, the property was taken over by Edward Smith. In addition to taking over this property, the prospector had rather renamed this operation as it was now known as the Silver Queen Mine Site. At the time, Mr. Smith had rather decided to close the mine site as he was facing some legal troubles that became resolved shortly after. Within this time period, Mr. Smith had rather reopened the mining project on November 1910, and had continuously work it. No additional work was done on the main workings as the surrounding area was being prospect at the time. This had also resulted in blasting, and sinking another pit that had soon reached a depth of 30 feet, and stoping was than commenced. Most of the legal actions were mainly against the Dominion Development, and Improvement Company, as the prospector wanted to change operations to Feldspar mining. Not only was Mr. Edward Smith the Manager of the company, but he was also the rightful owner of this project.
During 1911, Mr. Edward Smith would continued to explore the are further as he was more interested in feldspar production. This would result in abandoning the original workings as several pits were being blasted, and had reach a depth of 30 feet on different part of the property. It was also at this point in time when a minor amount of feldspar was uncovered within these pits, and shipped
Most of the mine is on the side of a small ridge of contorted garnet gneiss in contact with a white pegmatite and parallel to a limestone band. Both limestone and pegmatite are remarkable because of
the fact that they liberate hydrogen sulphide when crushed. The limestone is unusually coarse grained, bluish in color, and the pegmatite is of a pure white with druses showing good crystals of feldspar. Calcite, sphene and pyroxene can also be observed in the Pegmatite. The Mine has been worked primarily for apatite, which occurs associated with pink calcite and pblogopite. Apatite crystals are also found as minor constituents in the adjacent pegmatite. In mineable quantity, apatiteis restricted to an
are around the shaft, and mica pits have been worked more to the east The at the time mine was equipped with a boiler, boarding house, etc..
The deposits occur in irregular shapes with a tendency toward elongated, lenticular shapes, at the most ten feet wide. There is a preferred concordant relation to the enclosing rocks, but cross-cutting is common. The deposits may be asymmetrical in composition but in places show a banding or what might be a kind of crustification. In such cases, the walls are lined with pyroxene crystals, which in turn may be covered by mica books, and finally apatite in a pink calcite matrix grades into pure pink calcite in the center. Some deposits are devoid of apatite or of mica. But apatite, mica, pyroxene and pink calcite are the common association. The pyroxene crystals lining the walls show up very well in places where adjacent calcite has been dissolved. The crystals of mica and apatite range from fine to sizes of about 8 inches. Phlogopite show• at many places a very good asterism.
Other minerals observed within the deposits include hornblende, microcline, Scapolite, pyrite, marcasite. When limestone is the host rock, the mineralogy is slightly different: serpentine, zircon, hematite, a brown pyroxene, tourmaline, actinolite are found and apatite is practically absent. A remarkable feature of almost all mica-apatite deposits is the presence of small drusy cavities less than six inches across, lined with crystals of calcite, quartz, barite and pyroxene. At places, the apatite crystals have a glassy, uneven surface, as if the crystals had been partially fused. The walls, in some cases show alteration but are commonly very sharp. Where the country rock is a gneiss, it commonly grades into a biotite schist near the vein and then merges into the vein material. Some of the exposed walls in worked out pits show striations, but well polished and even grooved surfaces are more common. Most of the grooves have a low dip (15°). Though some of these features might conceivably be due to glacial action, others must have been produced by another process as they can be seen deep in the pits in places inaccessible to the glaciers. This was observed frequently enough to be called a characteristic of those deposits and is possibly the result of polishing from vein material.
