A discovery of quartz bearing pyrite was considered to have been the first reported rock formation to have place exploration states. At the time it was rather stated that the property was known as the Guelph Claim, before it became the Munro Copper Mine. Development within 1909, was also being conducted by the claim owners known as the Munro Mining Company. The Munro Asbesto Property was first uncovered within the staking rush in which was taking place within the Painkiller Lake area. With development proceeding there was a level that was establish, and cut on mines 61 foot section. This development procedure at the time was reported to have been extended within a quartz pyrite vein traveling to the east, and west before mining operations became ceased. Reports from the company had stated that the whole entire mining operation was entirely within the slates of the Timiskaming Series. In addition to this, the Munro Copper Property was rather reported to have been situated on Lot. 11, of Concession 2, within Munro Township, Northern Ontario, Canada.
1949- Staked by the Canadian Johns Manville Company, Limited
For the most part the Canadian Johns Manville Company was a wholly owned subsidiary of the Johns Manville Corporation, that was incorporated on September, 1918. It was also known that a great asbestos discovery was within limits of this property which the company might of been looking for at the time. Much of this asbestos discovery was reported to have first been uncovered on Lot 10, Concession 2, of Munro Township, Ontario, Canada. This prospect was rather known to have also carried several veinlets of fibrous asbestos that were up to one-half inches in width.
At the time it was rather stated that explorations on the property had been confined to the Munro Copper Mine Property. For the most part explorations on the Munro Property would continue from from August, 23 to December, 31, 1949. Diamond drilling within this property had totalled 56,369 feet in total length within that time period. It was rather stated that the company's main attention was aimed at preparing mining operations in order to develop a large open-pit operation. Further explorations on this property soon had resulted in more stripping in order to get this property ready for development. Other construction phases would also follow suit when a mill, crusher building, machine shop, store room and repair shop, office, and change room became constructed.
1950 - Staked by the Canadian Jonhs Manville, Company, wholly owned Subsidiary of Johns Manville Corporation.
Development of what was known as the Munro Property was continued throughout 1950. The company within this time period had also staked a total of 55 claims, which became situated in Munro, Beatty, Garrison, Harker, and McCool Township, within the District of Cochrane, Ontario, Canada. It was within 1950, when a huge amount of land stripping had commence that year. In total land stripping within the second quarter of 1950, had consisted of 599,065 tons of overburden which became stripped, and by the end of that year it had totalled 725,245 tonnes. By this time period the much need buildings were officially developed in which included the Mill, Crusher Building, Service Building, Office Building, Truck Garage, Pump House, explosive magazine, pit office, coal shed, and gate house. Diamond drilling within this time period had consisted of 90 surface holes, totalling 55,106 feet in length. Even development would start to escalate when the first reported production of 244,697 tonnes of ore became mined, and the mill had treated 228,498, at a daily average of 822 tonnes over a 278 day period.
1951- Canadian Johns Manville Ontario, Limited (Newly Incorporated in 1950)
For the most part the main mining operation of the Munro Property was being conducted in Munro, Beatty, and Garrison Townships, Porcupine area, within the District of Cochrane. Mining operations on what was known as the Munro Property had commence at full scales within 1951. Production that came from the mine had milled a total of 506,232 tonnes of ore with a daily average of 1,385 tonnes. This was rather taken from the open pit operation in order to sink a shaft, and to do bulk sampling on the C Ore Zone, which had lied 2 miles away from the A Zone. It was during 1951, when a two compartment shaft was sunk to a vertical depth of 314 feet, and a level became opened at 300 feet on claim L. 25634. Development work had amounted to 1,176 feet of drifting, and 2,972 feet of crosscutting. In addition to this, some overburden that totaled 159,528 tonnes was reported to have been stripped from the A Zone. By the end of December, the A Zone had officially totaled 884,773 tonnes of stripped overburden from this location. Diamond Drilling that was conducted by the company had totaled 28 surface holes, totalling 17,408 feet in length. Some more construction also continued when a Dry Rock Storage Building was partially developed, a compressor and Gate house addition was made, prior to development of Truck Tire Storage shed. A new incorporation was reported to have been made on March, 1950, when the Canadian Johns Manville Ontario, Limited became incorporated. It was a subsidiary company of the Canadian Johns Manville Company, Limited.
1952- Canadian Johns Manville, Ontario, Limited
Underground mining operations were continued on the C Zone of the Munro Mine Property during 1952. Development withing the underground working was taking place on the 300 foot level, when a total of 1,176 feet of drifting, and 2,972 feet of crosscutting was completed. No further underground mining operations were reported to have been done in 1952. Preparations were being made to mine the A Ore-body, when a total of 246,675 tonnes of overburden was stripped. This resulted in development of the Open Pit operation that had end up mining a total of 595,100 tonnes of ore from the A Zone, in which 566,348 tonnes was milled. It was also reported by the company that the Dry Storage Building was completed in 1952, and other construction had then taken place. Construction within 1952 had resulted in the development of a bunkhouse, ten family dwellings, and a lunch room at the pit. Additions also became made when the Concrete ore-bin was enlarge during that year also.
Mining operations on the Munro Mine Property continue to progress throughout 1953. In addition to this, there was no active underground development that had taken place the C Ore-Body Shaft location. Most mining operations were confined to removing 244,018 tonnes of overburden that became stripped from the A Zone, in Munro Township. A huge amount of ore was reported to have been mined from the open pit that end up totalling 634,087 tonnes of ore from the Open Pit on the A Ore-body. Production during this time period was rather escalating when the on-site mill had treated 665,930 tonnes of ore in 1953.
1954 - Canadian Johns Manville, Ontario, Limited
It was in 1954, when the Canadian Johns-Manville Company of Ontario, Limited, had continued active work on the Munro Property. It was during this time period of operation when development was being focus on the open-pit operations, with no underground development taking place. With development continuing the company had removed 360,696 tonnes of overburden that became striped from the A Ore-body. Another expansion project was underway when a vertical, four compartment shaft was sunken to a depth of 30 feet. The shaft at the time was known as the No. 1 Main Shaft which was sunken on Claim P. 1152, in Munro Township.
Mining operation in 1954, were mainly being confined to mining the A Ore-body when a total of 523,654 tonnes was hoisted. At the time it was also stated that milling operations were being done on a daily rate of 2,227 tonnes, in which had treated 552,654 tonnes of ore that year. Other construction within the Munro Property had included the development of a hoist-room, and electrical control room. Some construction also continued outside of the property when a six room house, and 11 new garages were built in Matheson, Ontario, Canada. Prior to development a considerable amount of work was done within the mill to control dust levels from the Asbestos.
1955 - Canadian Johns Manville, Ontario, Limited
Another huge amount of overburden was removed from the mine site in 1955, in which totaled 97,622 tonnes that was stripped from the A Ore-Body. Most of the construction in 1954, was being aimed at preparing mining operations further shaft sinking. With the much needed surface structures completed, the company had continued to sink the shaft further as it was now reaching a depth of 822 feet. Prior to development the company had constructed a haulage level that was cut on the mines 637 foot level, and a crusher level at 693 feet. Lateral development of both shaft operations is given in the section below

Diamond drilling in 1955, had consisted of 8 holes, totalling 3,464 feet from the surface, and 2 holes, totalling 410 feet from underground. It was at this time period when a steel head-frame became erected, which followed by the completion of a collar house, hoist house, dry house and office, and a boiler house that were built. It was at this time period when the Mill also became enlarge, and three more five room houses became built in Matheson. During 1955, the mine produce 667,326 tonnes of ore that became mined from the open-pit on the A Ore-Body. Production during this time period was rather heavy, when the on-site mill had treated 638,175 tonnes, at an average daily rate of 2,170.7 tonnes.
At the time it was rather reported that the main shaft was slash to have four compartments in 1956. Sinking had also continued when the main shaft operation was sunken to 882 feet. There was also a vertical three compartment service shaft that became sunk at a distance of 629 feet below the surface on Claim L. 4510. This resulted in cutting several levels that became opened up on the mines 80, 160, 430, 515, 560, 600, and 613 foot levels .The following gives the lateral development of all three shaft operations on the property.
No. 1 Main Shaft Drifting Crosscutting Raising Shaft Depth

Further diamond drilling on the property had consisted of 31 surface holes, totalling 12,211 feet, and 47 underground holes, totalling 15,959 feet. During this time period the company had also removed 552 tonnes of overburden that became stripped from the A Ore-Body. Other preparations were being escalated on the C Shaft when it was dewatered and re-condition, followed by diamond drilled, and bulk sampled. From all mining the company had mined a total of 641,832 tonnes from the open-pit, and 620 tonnes from underground. Production from the mill had treated a total of 622,317 tonnes of ore with an average daily rate of 2,095.3 tonnes.
1957 - Canadian Johns Manville Ontario, Limited
It was at this point in time when the C Shaft became made into a separate mining operation known as the Barton Creek Mine. As development escalated the shaft was sunken further to a depth of 571 feet, with a new level establish at 525 feet. For the most part diamond drilling within the Barton Creek Mine Property had consisted of 38 surface holes, totalling 17,833 feet. Other major structures also became added when a hoist house, core storage building, and an addition to the office, and dry house was built. Much of the new equipment that became installed had included two portable compressors of 600 Cfm, and a diesel generating set. Underground lateral development within the Barton Creek Shaft or the C shaft had totaled the following in 1957.
C Shaft Drifting Crosscutting Raising Shaft Depth
300 foot level 1,176 feet 2,973 feet ---------- 571 feet
525 foot level =======- 217 feet ----------
Besides developing the Barton Creek Mine, the company also focus on operating its Murno Asbestos Mine Property in 1957. Diamond drilling on the Munro Property had amounted to 2 holes, totalling 427 feet from the surface, and 41 holes, totalling 17,608 feet in length. A total of 3,100 tonnes of overburden was reported to have been stripped from the A Ore-body within this time period. From all mining the Munro Asbestos Project had produce 774,820 tonnes of ore, in which 292,574 tonnes was treated from the Pit, and 35,979 tonnes came from the underground workings. Milling operations within 1957, were reported to have operated on a daily rate of 1,990 tonnes.
Other construction projects within that year were being aimed at developing buildings to houses equipment. These structural development project included a mine air heater, a concrete mixing plant, and a furnace for the concrete plant. As these structures became developed, the company would installed a mine fan, and two air heaters on the surface. New Crushing and Milling Equipment had consisted a 4 by 8 foot Jaw Crusher, a vibrating feeder, and a dust collector, a fiber Mixer, and two impact crushers in the milling facility. The following provides the total lateral development that was completed to date below.

1958 - Canadian Johns Manville Company, Limited
All development within this time period had been taken over by the Canadian Johns-Manville Company, Limited. The company at the time had two holdings that consisted of the Munro Asbestos Property in Munro Township, and the Barton Creek Asbestos Mine in Beatty Township. In addition to this, the company reported that now work was commenced on the Barton Creek Mine at the time. Mining followed by milling operations were rather continuous on the Munro Asbestos Property throughout 1958. All development within this time period was focus on all the levels of the No. 1 Main, and No. 1 Service Shaft. From all development that became completed the company was able to finish 6,613 feet of drifting, 5,106 feet of crosscutting, and 1,479 feet of raising. A huge amount of ore was mined from the Open Pit, which totaled 445,429 tonnes, and another 210,654 tonnes was mined from underground. From all production the mill had ended up treating a total of 370,876 tonnes of ore, and was operated at a daily of 1,665 tonnes.
1959 - Canadian Johns Manville Company, Limited
Mining operations at the Munro Asbestos Property had continued to take place throughout 1959. It was during this time period when Open Pit Mining Operations became ceased in January, and most of the work was confined to underground mining operations. Mill feed within this time period was mainly taken from Underground Mining Operations, and the Open Pit Stock Pile. Development in 1959, was once again expanding the mining operation, when the No. 3 Internal Shaft was collared on the 637 foot level, and was sunk 94 feet below the collar. For the most part the company had also completed a total of 4,551 feet of drifting, and 2,053 feet of crosscutting. In total development footage the company had completed 1,837,436 tons of overburden stripping, 21,429 feet of drifting, 13,373 feet of crosscutting, and 4,329 feet of raising. Diamond drilling within this time period had consisted of 105 underground holes, that totaled 14,257 feet in length. A large tonnage of ore was milled, which 10,464 tonnes was taken from the open pit, 176,099 tonnes was mined from underground, and 218,397 tonnes was removed from the Stockpile. From all production that year, it was reported that the mill had treated 394,850 tonnes, with a daily average of 1,734 tons.
1960 - Canadian John Manville Company, Limited
Sinking the No. 3 Internal Shaft had continued when it was advanced by 71 feet, and had reach a depth of 802 feet below the surface. With the No. 3 Internal Shaft expanding, the company had establish a new level at 737 feet. For the most part it became reported that the company's workforce of 75 miners had completed 3,904 feet of drifting, 2,492 feet of crosscutting, and 824 feet of raising. Some overburden was also removed from the surface during 1960, which had totaled 4,700 tons of overburden. With development escalating the mine now had a total lateral development footage of 1,824,136 tons of overburden stripped, 24,344 feet of drifting, 15,865 feet of crosscutting, and 5,153 feet of raising. As the mine continued to expand, the company would end up completing 75 diamond drill hoes from underground, in which totaled 13,470 feet in length. Prior to production, the company had also completed extensive altercations to the milling plant. Much of this became done in order to improve the grade of the Asbestos fiber, and to increase daily production rates. By 1960, the company was able to hoist a total of 268,184 tonnes of ore which became hoisted from underground, while another 191,519 tons was removed from the surface ore-stockpile. With production escalating, the company's mill had ended up treating a total of 427,500 tonnes of ore with a daily production rate of 1,750 tons.
1961 - Canadian Johns Manville Company, Limited
Development within 1961, was mainly being confined to further sinking the No. 3 Internal Shaft to a depth of 949 feet below the surface. It was at time when another level became establish at a depth of 900 feet below the surface of the Munro Asbestos Mine. For the most part development within the mine had consisted of 3,779 feet of drifting, 1,943 feet of crosscutting, and 265 feet of raising. With this completed the mine now had a total lateral development footage of 1,842,136 tonnes of overburden stripped, 29,113 feet of drifting, 17,808 feet of crosscutting, and 5,418 feet of raising. Exploratory work within this time period had consisted of 79 diamond drill holes, totalling 15,130 feet from underground, and 31 holes, totalling 12,989 feet in length from the surface. Other major underground development was also advancing the westerly drive from the 635 foot level towards the Barton Creek Property. All hoisting within 1960, had resulted in 792,375 tonnes of ore from underground, and 202 tonnes from the surface. Production that came from the mill had treated 635,358 tonnes of ore, with a daily production rate of 2,093 tons.
1962 - Canadian Johns Manville Company, Limited
Fuether expanding had once again continued when the No. 1 Main shaft was advanced to the 1,200 feet below the surface. This resulted in establishing a haulage level on the 941 foot level, and a crusher level at 997 feet. For the most part the company had completed 2,415 feet of drifting, 1,658 feet of crosscutting, and 698 feet of raising. Diamond drilling within this time period had consisted of 68 holes, totalling 13,052 feet in length from underground. Mining within the Munro Asbestos Property was completed by blast holes stoping, and slusher drifts. Prior to development the company had replace the slusher drifts within the No.6 west stope, while being readied for production.Company predictions during this time period had predicted that this method of mining will be used as a standard in all future stoping operations. With the mine continuing to expand, the company would continue the drive westerly from the 635 foot level towards the Barton Creek and Beatty Areas. Prior to advancing this drive it was also stated that the B-1 Zone was encounter, and became extensively diamond drilled. Mining operations at the Munro-Barton Creek Mines had continued to produce ore when another 887,092 tonnes was hoisted from underground. A total of 207,367 was discarded, while the mill had treated 647,957 tonnes with a daily production rate of 2,300 tons.
1963 - Canadian Johns Manville Company, Limited
No additional sinking was done during this time period as the company had establish the 737, 835, and 941 main haulage levels. These newly developed level became cut on vertical depths of 712, 810, and 920 feet below the collar of the No. 1 Service Shaft. In all development that year it was reported that 600 feet of drifting, 2,063 feet of crosscutting, and 309 feet of raising was done. For the most part it was strongly reported that blast hole stoping, and Slusher drifts became the main source employed for removing the ore. At the time it was also stated that the company had replace the slusher drifts with mucking machines. Even a great amount of development had soon extended the 941 foot main haulage level in which had connected with the No. 1 and No.2 shaft operations. Other installations on this level had establish crusher chambers, and sumps prior to this development. For the most part the company had stop the westerly drive on the 635 foot level towards the Barton Creek Mine and Beatty Area. In addition to this, the mine it self was known for producing three types of Asbestos Fibres, that included the new 7-H grade used in asphalt mixes. Even more ore was hoisted from the underground workings during that year, and had totaled 1,081,708 tonnes. From all production the mill had treated a total of 785,522 tonnes, with an operating daily average of 2,410 tons.
1964 - Canadian Johns Manville Company, Limited
Milling and mining operations at the Munro Mine had continued from January, 2, to July, 31, 1964, when mining operations ceased. No additional development work was reported to have been completed within the Munro Mine in 1965. A total of 409,877 tonnes of ore was hoisted from underground, in which the mill had treated 360,980 tons at a daily average of 2,028. For the most part it was during this time period when active development was focus on the Reeve Mine Site that was located in Reeve Township at a distance of 40 Km from Timmins, Ontario, Canada.
