The Whistle Copper-Nickel Property was first discovered in 1907, which became situated on Lot. 6 within the fourth, and fifth concessions of Norman Township. It was during the winter season when extensive diamond drilling was commenced in ore to define the ore-bodies. After obtaining satisfactory results the company had now prepared the engineering phase of a prospect shaft. For the most part this property was rather located 4 miles from the Moose Mountain Branch of Northern Canadian Railway. Prior to development the company had also made a contract to connect a spur line from the railway line to its mining operation. During this time period much of this copper-nickel discovery was made by the Dominion Nickel Copper Company.
1908 - 1909 - Dominion Nickel Copper Company
No extensive development was done during that year as diamond drilling had still continued, and the exploration shaft had reach a depth of 50 feet. By 1909, the company had started on constructing a spur line from the Canadian Northern Railway to the mine property.
1910 - Dominion Nickel Copper Company
It was in 1910, when the Dominion Nickel Copper Company had officially completed the spur line connection from the railway to the mine. This resulted in further purchases when the company had also added locomotive, and ore cars towards its operation. Even more extensive development had taken place when a rock house was construct. Following the completion of this development the company had installed 18 by 36 Jaw Crusher driven by two motors of 75 H.P.and 40 H.P capacity. Electric power during that time period was also taken under contract from the Wahapitae Power Company. Other development during that time period had also included the power house that was equipped with a 1,800 foot compresor driven by 300 H.P. Motor. With the power nearly complete the company had also added a transformer house that was built on concrete.
With the mine operating steady it was also within this time period when mining was officially started by open-cut methods. A total of 50 miners became employed during the start up production year for this copper-nickel project.
1911 - Dominion Nickel Copper Company
Mining operations at the Whistle Property were operated on a steady basis throughout the year of 1911. Development during this time period was mainly confined to developing the main adit that was driven for a distance of 1,200 feet into the hill by the rock house. Far more development would continue to take place when a 50 foot raise was driven at the end of this adit.
1912 - Dominion Nickel Copper Company
Mining operations on the Whistle Property were continued on the North Nickel Range Portion of this property in 1912. Most of the development during that time was mainly focus on developing its main adit level further. By this time the company had rather continued this adit for a length of 1,200 feet before raises became driven to test the ore-bodies. This development phase was also followed by a minor amount of drifting, and crosscutting in which raises became driven to the surface. No other development was done by this company as it was re-organized in order to place the Murray Mine into production. No production was ever reported to have been achieved at this mine site as the company didn't ship any ore from its copper-nickel property.
1994 - International Nickel Company of Canada, Limited.
Even more openings were made when INCO had re-opened it Whistle Copper-Nickel Property for explorations. For the most part it was reported that the property was place under exploratory phases in 1907. It was later operate again once INCO had take over this operation in 1988. By 1994, INCO had once again decided to place the Whistle Copper-Nickel Property into production Mining operations at this property were continued till September, 21, in which a total of 3.1 million tonnes of ore was produce. Prior to its closure the company had also reported that 8 cuts were mined in which four more cuts were to be taken. A total reserve estimation of 1.5 million tonnes of ore was left to be mined with some underground potential.
1995 - International Nickel Company of Canada, Limited
Mining operations at the Whistle Nickel Property had continued on as eleven benches were mined, with three remaining. Production was rather high during this time period of operating as the daily rate was between 4000 and 5300 tonnes of ore. Even more changes became made when an magnetic separator was installed in order to improve the pyrrhotite grade, but decrease production by 2300 tonnes daily. Assays which were conducted had rather range between 1.1 to 1.2% Nickel. By 1995, the company had kept ore reserves increased as explorations indicated 1.8 million tonnes of ore grading between 1.1 to 1.2% Ni.
1996 - International Nickel Company of Canada, Limited
Production amounted to 5,000 tonnes of ore on a daily basis, which produce 150,000 tonnes of ore in 1996.
1997 - International Nickel Company of Canada, Limited
Total ore reserves estimated at 1,650,000 tonnes grading 1.20% Ni - Cu?
All mining operations at the Whistle Mine became place on-standby procedures as ore was yet to be exhausted from this location. A total ore reserve estimation of 1,650,000 tonnes ore, grading between 1.1 to 1.2% Ni at closing time. This was followed by several other mining operations which included the Levack, McCreedy West, and Little Stobie Mines.
1999 - Falconbridge, Limited. - Explorations conducted on the Norman Copper-Nickel Property to the west of the Whistle Property.
Total inferred resources estimated at 7.6 million tonnes of ore, grading 1.58% NI and 1.28% Cu on the Norman Property
Diamond drilling was commenced in 1999, by Falconbridge, Limited who had conducted explorations on the Norman Copper-Nickel Property. The property is rather situated to the west of the present ore reserves of 1,650,000 tonnes of ore within the Whistle Copper-Nickel Property. Most of this exploration phase was being conducted on the northeast corner of the Sudbury Igneous Complex. Prior to this diamond drill program the company had encounter a high-tonnage inferred ore reserve estimation of 7.6 million tonnes, grading 1.58% Ni, and 1.28% copper. For the most part the Whistle Copper-Nickel Property was also owned by INCO during this time period of exploring the ground further.
Full history, production, assaying, and development to be continued.
