It was following diamond drilling that was first commenced in 1954, that Algom had obtained a contract in 1955 for the production of $206,910,000 worth of concentrate from the Quirke, and Nordic Mines. Within the zone it was reported that 47,000 feet of drilling in 109 holes had been spaced at about 250 feet apart on strike and 450 feet downdip to outline the Nordic Reef. This resulted in estimating an average thickness of 10.5 feet, with the strike being N 0.80 degrees W and dip 12 degrees to 25 degrees No with the averaging being 0.17 degrees.
By 1955, the company was well into production when six levels became fully constructed on the mines 100, 310, 450, 600, 750, and the 850 foot level. Generally the whole entire shaft operation was further experiencing shaft sinking phases when it was reaching a depth of 890 feet. Company officials, and its team of dedicated miners would end up opening these section up by drifts and crosscuts, with some raising procedures. More so the Rio Algom Mines Limited had other plans when it was now engineering its own 3,000tons per a day milling facility. Most of this construction phase would all be completed by January 1st 1957, when milling was now being done at the former Nordic Uranium Mine Site. Production from the mine was rather coming from all the levels, and a huge amount of ore was being hoisted, and stock-piled at the time. Underground working and drilling had also indicated ore grade sections in the basal reef particularly in the eastern parts of the mine and in a bed overlying the main reef. By this time it was planned to sink the 6-compartment shaft to a depth of 890 feet by December 1955, and the mine workings laid out for trackless mining using jumbo drillers and bulldozers.
In 1960, the Six Compartment Nordic No. 1 shaft was undergoing its own expansions when the shaft was sunken to a depth of 1,331 feet. Development on the No. 1 shaft was being further commenced when the company's hard-working miners had now constructed 5,653 feet of drifting, 1,728 feet of crosscutting, and 16,684 feet of raising that was done. By the end of December, 1960, the mine it self had total development footage of 57,550 feet of drifting, 9,336 feet of crosscutting, and 92,735 feet of raising. At the time the company also commence its own underground diamond drilling phase of one single hole that totalled 960 feet of core sample.
Within 1960, the Rio Algom Mines Limited had also place construction phase towards a Water-softener building, and its own fuse and cap magazine. The much need installations towards these building had included a Cochrane water-softener, with accessory equipment, and a ventilation fan that was mounted with a 400 H.P Sheldon Motor. Company officials from the Rio Algom Mines Ltd. would also hoist a significant amount of ore that totalled 1,044,600 tons. Never to say but the Nordic Uranium Mine was rather being transformed when several tons of ore became extracted. In addition the company would also open up two newly developed levels that became stationed on the mines 950, 1,050, and 1,300 foot sections.
All development within 1962 was mainly being confined to sinking the six compartment vertical shaft to a depth of 1,780 feet below the shaft collar. Much of this also establish two more levels that became driven on the mines 1,450, and the 1,700 foot section. In general this would also construct more lateral development when 8,819 feet of drifting, 6,275 feet of crosscutting, and 19,759 feet of raising was done within that year. In addition the company would now enlarge its development footage when the mine consisted of 74,106 feet of drifting, 19,394 feet of crosscutting, and 131,561 feet of raising. Company officials from the Rio Algom Mines Ltd. would also further expand a drilling program that was aimed towards the surface and the mines underground workings. A total of six underground diamond drill holes, that totalled 866 feet of core sample was taken, while another 10 surface driven diamond drill holes that totalled 14,700 feet was also being assayed. More so the company and its crew of miners would also hoist another huge amount of ore that totalled 1,111,170 tons. Never to say the company would also add more mining equipment that included 6 slushers, 1 portable compressor, 10 mine cars, 3 trolley locomotives, and 3 loaders.
By the following year in 1963, the whole entire mining operation was rather transforming when mining and milling had taken place. Most of this discovery was also considered to have been located on 140 claims within the townships of 143, 149, and 155. No further shaft sinking phase became establish within this year as the Rio Algom Mines Ltd. would only be confined to the newly developed levels. Development during this time period would end up consisting of 12,031 feet of drifting, 1,780 feet of crosscutting, and 22,840 feet of raising. The Rio Algom Mines Ltd. had also started on a newly developed drilling phase that establish three diamond drill holes that totalled 397 feet of core sample. Within this time period the company, and its hard-working crew member would also end up hoisting a total 1,147,370 tons of ore. Production from the milling facility that year soon had totalled 1,141,500 tons of Uranium Oxide ore that became processed and treated. Milling within 1963, was rather upgraded when the capacity was now reaching a total of 3,309 tons of ore on a daily basis. Generally the Nordic Uranium Mine was now comprising with more lateral development when its had consisted of 86,137 feet of drifting, 21,174 feet of crosscutting, and 154,401 feet of raising. It was also said that the Rio Algom Mines Ltd. would additionally add more equipment that consisted of 1 Exhaust fan for the west raise, 20 mine cars, and a lathe.
By 1964, the Nordic Uranium Mine was rather operating at a heavy pace when the miners had hoisted another huge amount of ore that totaled 1,186,550 tons. From this massive output the company was able to process 1,185,000 tons of ore at a production rate of 3,425 tons of ore on a daily basis. Even development within the Nordic No. 1 shaft was exploding when the company and its workforce was able to construct another 12,711 feet of drifting, 188 feet of crosscutting, and 22,237 feet of raising. Diamond drilling would also take place when nine underground diamond drill holes became driven within that hard rock, and had totalled 10,842 feet of core sample. More so the Nordic Uranium Mine was now becoming pretty massive in size when it had totalled 98.848 feet of drifting, 21,362 feet of crosscutting, and 176,638 feet of raising was done.
Not much was done within the year of 1965, besides some lateral development that took place within all the levels. Much of this development it self had consisted of 8.984 feet of drifting, and 25,364 feet of raising that was done on the Nordic Uranium Mining Operation. During this time period the company did not achieve any construction phase on its crosscutting procedures within the mine. Besides that it was also reported that the company and its miners had hoisted another great amount of ore that totalled 1.187.870 tons. Milling operations within that year alone would end up processing and treating another massive yield of ore that totalled 1,190,000 tons from a daily input of 3,449 tons of ore. As production and development continued the company was now on another move when another series of one surface diamond drill hole was completed, and had totalled 746 feet of core sample. More so the whole entire Nordic Uranium Mine was once again experiencing a new footage towards all lateral development. By the end of 1965, the Nordic Uranium Mine was now comprising of 107,832 feet of drifting, 21,362 feet of crosscutting, and 202,002 feet of raising.
Company officials from the Rio Algom Mines Ltd. would also change many speculations within the year of 1966. Most of this historical change would be added when the company was maintaining the upper levels with bacterial leaching, and had taken extreme measure of treating the water before discharging it. By 1960 the underground water had became so acidic due to bacterial oxidation of pyrite that severe corrosion problems had arisen. The Acidic Ferric Mine water had also leached out uranium compounds and the uranium oxides had rose to 0.03 kg per a ton. All production within the year of 1966, was strongly taken from stope sections that we're being work on from the 7th to the 14th level. Production within that year would end up hoisting a total 1,284,650 tons of ore that came from all eight levels. Further so the company would additionally develop these levels when 9,610 feet of drifting, and 22,827 feet of raising was accomplished. Milling within that year was also averaging a great amount of ore on a monthly basis, that had its own total of 110,000 tons, and would end up processing 1,285,400 tons on a daily output of 3,704 tons. More so the company would end up producing a whack of uranium oxide that totalled 2,749,965 tons.
Milling within 1968 was continued from January till July when the mill became closed down for a short period of time. Company officials from the Rio Algom Mines Ltd. had also estimated that the mill would be back in operation by the year of 1972. However, much of the Nordic Mining zone was rather being transformed when the company was expanding its operation stages. Most of this became completed when the Rio Algom Mines Ltd. decided to test their luck at finding new reserves within the Nordic Uranium Mine. In addition a diamond drilling phase had soon intersected more reserves that we're hidden within the Lacnor Uranium Mine. Much of this was done because the company wanted to extract the rich ore on the South Limb Structure. These new discovery stages would end up expanding the bottom level of the Nordic Mine into the Lacnor Mine shaft. Eventually the company, and its team of miners would end up expanding this mining operation when a whole new series of lateral development became constructed. Much of this expansion phase had included 213 feet of crosscutting, and 2,138 feet of raising that was establish. Hoisting from the mine was rather experiencing a shortage of ore when the company had only obtained 655,657 tons of ore from the Nordic Mining operation. Even milling was considered to be very slow as the company was only able to process a total 733,600 tons of ore. During this time period the Nordic Mill was also processing another huge amount of ore for the Quirke Mine that had totalled 194,524 tons of uranium oxide. Nevertheless, the company would still control water contamination when it had still adapted the bacterial leaching process on the less productive stope sections. Generally these stope sections we're rather considered to be exhausted from any more material, and had no more extractions phases being done on them.
Much of the whole entire Nordic Uranium Mine was now being completely shut down between 1969 and 70. All of this was caused because the mine was not producing enough resources and production from the on-site mill would only process less then 10,000 tons of ore in 1969. Even a small amount of crosscutting cutting was performed but no raising was done within this time period of becoming abandoned. By 1970 the whole entire mining site was experiencing its own shut-down as company officials did not perform any more development, production, or exploration procedures. The Nordic Uranium Mine would start to be rehabilitated as the company no longer had any use for this operation.
The main units that occupy the area are exposed as Keewatin Sedimentary and volcanic rocks, which includes Algoman Granite. Lower Mississagi Green Arkose, and pebble bands of lower Missisagi polymicitic conglomerate along with lower Mississagi Grey Quartzite, lower Mississagi Argillite and argillaceous quartzite. Huronian Units are commonly over which a dip-and-scarp topography is developed, which strikes east-west and dips north at 10 to 25 degrees. The foremost East Striking and Northwest Stiking dikes are known to occur within vicinity of the main mine workings at the Algom Nordic Uranium Mine. One of the major faults that's in proximity of the mine is the Horne Lake Fault that strikes northwest in vicinity of Horne Lake and highway 108. Diamond drilling that was extensively done had also revealed a northwest trending channel of thicker Lower Mississagi Sub-Arkose and conglomerate lying between the approximate granite-metavolcanics boundary and a ridge developed over siliceous metasediments including iron formation that can be traced under the Huronian by means of a magnetic anomaly. Some of the main ore zones that are associated with bed of conglomerate are known for being 19,000 feet over widths ranging from 4,400 to 6,000 feet. It also on the western margin at Nordic, where the beds wedge out against the greenstone basement
One of the main Reefs at the Nordic Mine, is known to consist of Conglomerate or conglomerate with quartzite ribs, and is 10 feet thick with an average grade of 2.5 lbs of U3O8 per ton. Its also at the west end of this mine in the upper levels where it rests on basement, and to the east by as much as 60 feet of arkosic quartzite and conglomerate. For the most part, this bed is referred as the Nordic Reef, the Y Reef or the Buckles Reef. It also in the eastern part of the mine workings, where a basal reef, known as the Lacnor Reef or Z Reef, which lies on the basement and may reach 21 feet in thickness, where only a limited mining was being carried out, and obtained assay grades of 2 lbs of U3O8 per ton, but is generally considerably less. The eastern portion of the Nordic Uranium Mine is within an upper reef, which is also describe as the X Reef, that situated 15 to 25 feet above the Nordic Reef and is minable at a five foot height. This reef is known for continuing to the east over the basement high that seperates the Nordic and Pardee Channels, and is the main reef within the Pardee Channel. Some very high-grades of Uranium content was taken from this section of the workings that would amount to 4 lbs of U3O8 per ton over five feet, but was usually less than 2.30 lbs of U3O8 per ton over 5 feet. For the most part, the Pardee Reef is known for being approximately the same thickness over the eastern part of the mine workings. Another conglomerate zone that's 50 feet thick contains width assaying 0.05% U3O8 per ton. A lower section of the Lacnor Mine is known to currently respond to the basal bed at the Nordic Mine which averages 12 feet thick. Its also the intervening quartzite beds which are associated to conglomerate, which normally are below ore grade and about 12 feet thick.
