in 1968, the No. 1 Lockerby Shaft was additionally sunken to a depth of 49 feet below ground levels. During this time period the mine was rather reported to have been transforming when the company decided to establish the much needed structures to run this operation. Most of this development and installation had included 1 steel head-head frame, one hoisting house, one pump house for water supply, another pump house for sewage disposal, a dry and shop building, one water line, a substation, and one sewage disposal line. Nothing else during that period was commenced as the Lockerby Mining Property was just becoming developed.
Another transformation was being made when the company had decided to sink the No. 1 Lockerby Shaft to a depth of 1,674 feet below ground levels in 1969. Much of this development had also constructed stations that we're cut on the mines 275, 575, 850, 1,000, 1,175, 1,350, and another level cut on the mines 1,525 foot section. More so the company, and it's crew members had also constructed 400 feet of crosscutting within these levels. Never to say the company also had underwent its first underground diamond drilling program that totalled 214 feet of core sample. Much of the work was also place under contract as the Macisaac Explorations Limited had taken control of this site. Further development was also taken place when the company was well constructing this mining area with the much needed structures to run this operation.
By 1974 this mining operation was well underway and producing good amounts of ore resource while developing underground workings. At this point the Production shaft was at about 1000 feet below ground levels when another expansion to the exploration shaft occur. This time the shaft was deepen to the same level as the Production shaft and two other shafts became constructed. Both of these newly design shaft had been sunken down to 500 feet in no time. As this mine boom the workings became carry out on 3 producing levels which connected them with the other shafts.
By 1978 the Lockerby Mine soon came to its first short closure as upgrades we're needed to keep productions going. After one year of fully upgrading this mine site, the Lockerby Mine once again enter production phases. After a long period of development and ore extraction the mine was once again close due to more upgrades on this mine.
Another buy out was made in 1995 when First Nickel Incorporated purchase this claim from Falconbridge Nickel Mines Limited. Soon after First Nickel Corporation started to take charge of the Lockerby Mine when it reopen in 2005. At this point the mine was producing heavy ore resources till it came to another closure in 2008. Most of the reasoning for this closure was due to Metal prices being to low to operate. For now the mine still stands under a maintenance program to keep it in operational condition.
