The Temagami Sulphide District of Ontario, Catnada was rather known as a small native village that grow into a major industry for logging, fur trading and eventually mining that took place here. Dan O'Connor was rather a well known individual who had lots of capital to fund a whole new mining area along with building a reliable transportation route that at the time could only be reached by the way of canoe transportation. This was rather Dan O'Connor's first time in this settlement town which resulted in a discovery of mispickel ore deposits and sulphide zones containing gold and silver values. The Big Dan Claims were rather the first to be further prospected at a much larger scale during the year which resulted in a large amount of exploratory work that was completed by a small workforce of men that made this mine the first to be discovered in this new area. Net Lake at the time was being widely prospected and land was eventually purchase from Dan O'Connor that was taken up by the Canadian Copper Company of Sudbury, Ontario, Canada.
The Big Dan Claims were mainly situated on the southwest shore line of Net Lake, and were being extensively prospects by Dan O'Connor at the time of securing this portion of the claims. Much of the deposit was described as a high tonnage auriferous mispick ore-body that was mainly deposited into an altered slate country rock, and had contained pyrite, Arsenopyrite, and Chalcopyrite. Most of the area was rather being further explored when the sinking of test pits had commenced in order to evaluate this major deposit of mispickel further. Much of the gossan sheared zone was traced N. 030 degrees E, and had been stripped for more than a quarter of a mile that had a width of 100 yards in some places. Test pitting at the time was rather ongoing when several of these pits were sunk, and two of them had also reach significant dimensions in regards to exploring this virgin land further. The most southerly pit was 27 feet long by 4 feet wide and 3 feet deep, in which the ore pile beside it had consisted of pyrite, chalcopyrite, and arsenopyrite. It would also result in the next large opening to the north which was a trench that was sunk along the steep hill side of the workings. For the most part, this trench had also disclosed a solid band of mispickel, that was 59 feet long and about a foot thick on average, running down at least 10 feet as shown in the trench, but having no distinct walls. Assays that were taken from this section had shown the ore to contain $3.72 in Gold (Au), $2.52 in silver (Ag) and 14.4% arsenic per tonne of ore mined. At the foot of the hill and little bit northwest of the Trench, there is another pit yielding rich ore of mispickel, and containing a considerable quantity of copper pyrite with very low gold and silver values in association. At about 100 yards to the north, there was another fairly large pit that had showed a band of ore that was very rich in mispickel, a sample of which had assayed $9.30 in gold (Au) and $1.32 in silver (Ag) per ton of ore mined. Much of the assays made on these ores had also ran as high as $1 to 31.20 in gold and silver values, and had average roughly $5.75 per tonne, which all the samples of ore had average more or less arsenic. Prior to this, it was also stated that the carefully selected arsenic could also be mined as a secondary resource due to the fact that arsenic was at a high value at the time which range from 4 1/2 to 5 cents per pound of mined arsenic. Estimations on the ore reserves at the time were hard to manage due to the charcturistic of the ore-body within these workings, but it was rather stated that they would hold a great amount of reserves to this property. Other statements reported that the arsenic ore was fairly different from that of the Deloro arsenic gold deposit of Ontario, Canada, in which they were mixed in with sulphides, and had very little quartz to no quartz and occurred in ore-bodies within shear zones in slate, penetrated by dikes and disease.
Dan O'Connor at the time had also sold large number of his stakings to the Canadian Copper Company that had interest in further evaluating the deposits on Net Lake at the time. Exploratory work by the company had mainly taken place to the west of the Big Dan Claims that were evaluating the copper pyrites in the area. This had resulted in sinking two shafts to explore this ore-body further in which the first shaft was sunk to s depth of 30 feet and the second one had reach a depth of 15 feet below the surface. Due to the isolation the company would also build a camp containing four log cabins on the west shore line of Net Lake, in which had closed down on Nov, 1, 1898, for the time being. Most of this had mainly been done in regards to exploring the Western side of Net Lake known as the Mukwa Claims that carry a considerable amount of copper-nickel ore in great quantities. More work was also done on the Friday No. 1 and 2 claims that were similar in appearance to that of the great Sudbury copper-nickel ore-bodies and the Mukwa Claim group. At the Friday No. 2 claim, there was two opening made on this part of the Big Dan Claim group which showed masses of chalcopyrite and pyrrhotite, and the rusty rock surface could be traced on top of the hill for quite a long distance. For the most part, the Red Hill Claims were fairly different from that of the ore discovered in the area as they carry copper pyrites with very minor pyrrhotite in quartz veining up to 4 feet wide and had resembled the copper deposits of Bruce Mines, but carry important gold values.
Prospecting on the Big Dan Claims, and around Net Lake had continued onward for about 8 years, when the property was taken up by the Temagami Mining and Milling Company in 1905. It was at this point in time when much of the ore that was taken from the mine had been mainly done by open-cut methods, and hoisted by a skip for further processing. As the ore had become hoisted, it would be loaded onto a Blake Jaw Crusher in order to be crushed at decent sizes mesh of 3inchs for concentrating purposes. Much of the ore that was crushed had undergone a secondary crushing for the purpose of resizing the ore that came from the Big Dan Open Cut at the time. The ore that was crushed would move onto further processing when it was place into Kriem Air Separators in the concentrators compound at the time. It was later dry and baggage in order to be hauled by horse wagon to the newly designed Grey Siding which was a drop off and pick up place for supplies and processed ore that came from this mine.
Before this individual had entered the business game he was commonly born and raised in Pembroke, Ontario, Canada. But eager enough he decided to move from Pembroke to Sudbury to face is real dreams in learning more about the economy, life and industry when he became Sudbury's second Mayor in 1894. While serving as a mayor for three years in Sudbury he decided to move on to bigger and better things. While prospecting the far north this small business men came across a native settlement which wasn't really name or anything. So with power to do so he establish a small community which was found as Temagami. He also created his owm hotel operations on Temagami Lake which are identify as Lady Evelyn Hotel, The Temagami Inn and the legendary Ronnocco Hotel.
By 1906 the mine was considered to be at a steady pace when company officials decided to hire the Temagami Milling and Mining company to develop their own Mining and milling facility. As ore resource came from the mine it eventually became extremely exhausted as it went on to further processing. Besides constructing their own mining mill company officials even created a railway siding which was identify as Grey's Siding. This network of railway became the main shipping network for ore that was processed at the mill. Generally mill processing was conducted for the purpose of refining gold and silver from ore material which came from the mine. This material was extracted by an open cut method commonly known as an adit which haul the ore with a skip. As this massive piece of machinery operated it would then dump the ore into a blake Jaw Crusher. In general this piece of machinery is commonly design to break up rock particles for further processing. By the time this stage was complete the massive ore was then dry before it went on to roll crushers for sizing. This method later processed the ore in three Kriem Air Separators in the mills compound, Once these separators had concentrated the ore resource it was then baggage and shipped away to their clients. Nevertheless another material known as arsenic was also mined at this time period. The Arsenic vein which was discover in the Big Dan Mine was estimated to be 59 feet long and 1 foot wide.
Mining operations had continued throughout the year by Temagami Mining and Milling Company in 1907, and had shortly ceased on April, 1908. Most of the work at the time was mainly being confined to opening up an Adit level that was driven into the hill side for further exploratory work of the mispickle deposits. Other development at the time had also escalated when two shafts were sunk on the deposit, and had been approximately 50 feet deep before ceasing mining operations at the Big Dan Gold Mine. Before ceasing mining operations a fatality had occur on January, 3, 1908, when Andrew Gowanlock had been instantly killed as he work as a Machine operator within the Big Dan Project. Most of this incident had occurred when 4 holes were being load and fired off in the morning time hours in order to obtain ore for further processing and shipping. Prior to this, his partner who was with him at the time had stated that only three blasts went off, and that a remaining explosive cap was still hurried under the pile of rubble. It was at this time when his partner and Andrew Gowanlock had started looking for the undischarge explosive when all a suddenly Mr. Gowanlock had hit the explosive with his pick that would kill him instantly.
Mining operations at the Big Dan Mine were fair large and consistent as the mine had operated from 1898 to 1908, in which had been active for 11 years of its life time. The property was shortly after staked by the newly formed Big Dan Gold Mines, Limited, who had re-examined this property in 1949. Most of the work by the Big Dan Mines, Limited had consisted in carry out a resistivity survey on the property, and additionally drilling eleven diamond drill holes, totalling 2,664 feet in length. There was also additional sampling work that was also done on the property prior to exploring the deposit of mispickle ore further. The best assay that was taken from sampling had average 0.64 ounces of Au per tonne, and 11.2 ounces silver per tonne over 0.4 m, but for the most part assays returned trace or nil values in gold. These assays were most likely done on the section of copper pyrites that had contained relatively low gold values but high silver values. Diamond drilling that was undertaken had relatively showed that the deposit was systematically zoned with a central done of arsenopyrite, and carbonated veinlets passing outwards into a zone of pyrrhotite, then pyrrhotite with carbonated veinlets, and finally an outer zone of country rock intersected by carbonated veinlets. The ore-body mainly consists of chalcopyrite, pyrites, arsenopyrite, calcite, quartz, and pyrrhotite that's associated with the shear zone. Much of the shear zone that contains associations of all the mineral listed above strikes north and south with a steep dip to the west. This zone is rather to Sean stained on the surface, and has a width at the tunnel to about 50 feet, and a length of about 1,000 feet. There is also two shafts that were sunk to the north and south ends of this deposit in the early years of mining. It's also occupied by an open cut and a tunnel that is midway between the two shafts operations, the open cut is about 18 feet wide and the tunnel rather goes on for a short distance where it intersects with a stope section. Further so, the area is rather known to be extensively sheared, and brecciated into zones that are associated with basalts of Keewatin Age. The basalt that was described as slate in the golden days is massive except for within the Shear Zone. Ore at the Big Dan Mine had mainly been associated with this shearing and basalt to a point where it normally occurred as small veinlets, and grains dessiminated throughout the rock. Some pure ore can be seen in which contains angular fragments of rock, showing that the country rock had been brecciated, and that the ore had mainly filled in between the fragments. There is also a total of 3 dikes on the property, mainly a quartz porphyry dike, a diabase time and a much basic dike. The quartz porphyry dike rather occur at about 25 to 200 feet west of this ore-body, and is known to strike a little east of north. To the east of this ore-body, at about 300 to 1,000 feet there is a very basic dike striking north westward, and the second dike mentioned is known to be a basic Diabase Dike. The dike referred as basic is an altered gabbro dike that is exposed immediately east of the railway tracks. The dike is rather post granite in age, and in addition to the basic dike, a northeast trending biotite-lamprophyre is known to exposed in rock cuts on the railway line to the east of the Big Dan Deposits.
Other changes had occurred in 1965, when United Reef Petroleums, Limited had taken over the Big Dan Property. Most of the work at this time had consisted of geological mapping and a ground magnetometer survey coupled with additional sampling. Some of the best results obtained from the sampling program had indicated 0.21 ounces of Au, and 2.19 ounces of silver per tonne of ore bulk sample.
The Big Dan Mine was commonly destroy by a massive forest fire which had swept through the city of Temagami, Ontario, Canada. It was commonly known for the closure of several mine operation within this area. Besides destroying mines it also burn down the Temagami railway station which was built two years before this massive fire happen. By no time the train station was rebuild and served as a junction point for the Timiskaming & Northern Ontario Railway line once again.
The Big Dan Mine is commonly known to be apart of the Green Stone Belt which dates back to 2,687 million years ago. However, indications of this formation have indicated that this land was apart of active volcanism which took place 49 million years ago. Geological identification has claim that this partial land formation is made from Metamorphosed igneous and Sedimentary rock deposits. The big Dan mine is commonly apart of the younger volcanic complex that's made from Mafic Vocanic Rocks in the Temagami Greenstone belt. Indication of this formation are known to consist of Intrusions which penetrate the complex and its three major zones. These zones are commonly characterize as the Northeast Arm Deformation Zone, the Link lake deformation zone, and not least the Net lake- Vermillion Lake Deformation Zone. Mineral formation at the Big Dan mine is commonly known for consisting of Arsenopyrite, Chalcopyrite, Pyrite, and Pyrrhotite. The metals which were extracted from this location are also identify as a Nickel, Copper, and Zink shear zones.
Besides just the big Dan Mine Dan, O'Connor also own and operated two other mining ventures which were identify as Little Dan Mine and the O'Connor Mine projects. The Little Dan Mine was mainly an underground gold producing mine located on the shores of Arsenic Lake in Temagami, Ontario Canada. Beside only little Dan Mine, the business man also own his own surface mine operation at the O'Connor mine projects. This mining venture was known for the development of several open trenches and pits which extracted many different resources. Some of the resource which became extracted from this area include primary commodities like Copper, Sulphur, Pyrite, and Nickel. The other secondary commodities are considered to be a low grade gold and zinc veins.
However, many mines soon face difficulties when the Temagami Land Caution had hit in 1973. This massive regulation soon enforce a territorial dispute between the Teme-Augama Anishnabai.culture. It was commonly known for abandoning the sales and development of mines in Strathy Township that's located in Temagami, Ontario, Canada. Some of these operations which fell under this act included mines like The Kanichee Mine, Beanland Mine, Big Dan Mine, Hermiston- McCauley Mine, J.W Barten Mine, L.D Norrie Mine, Manitoba and Eastern Mine, Ousloud-Hurst Mine, Sey Bert Mine, Sherman mine and the Temagami Mines. Nevertheless, the Temagami Land Caution had only lasted for a few years before the Supreme Court of Canada had decided to lift this act in 1995. From this point onward the Temagami Region was officially open for any kind of mining operations and sales. Some very odd structures do exist in the region when looking at satellte images of different parts of the Temagami area of northern Ontario Canada.
