Mining operations at the Colonial Silver Mine had all taken place in 1909, when a foundation was being poured for the concentrator. This whole entire project was also being developed under the direction of Mr. G.W. McCaskell at the time. No other development had taken place as the mine was not put into operation at this time period.
Mining operations were shortly after resumed by the Colonial Silver Mines, after being reported to have been suspended for about a year. Almost all the work within this time period was mainly confined to developing an adit that was located 100 feet from the mill. It was also during this time period when it became further driven, and had opened the adit for a distance of 400 feet. The whole entire adit was rather stated to have been driven in a southwest direction. At about 250 feet from the mouth of adit there was also a shaft, which became collared to a depth of 250 feet on the vein zone. From the bottom of this shaft there was also level extended for a distance of 250 feet that had been opened up to run with the vein zone. Even far more development would continue when the company had sunk a winze shaft to the depth of 75 feet. There was also a raise which was put throught in order to connect with another adit level that was located 30 feet above. As development continued the company would also commence stoping operations on the 250 foot level. Much of the equipment which was installed had included a hoist that was now place on the adit level of the winze shaft. It's main function was to hoist all the ore from the lower workings, where it would then be trammed from the adit level to the milling facility. Development had also occurred on the old adit working which were located 500 feet east of the working adit. For the most part it was reported that this adit became extended by 1,000 feet of drifting, and crosscutting. Some more work was also done on the adit, which was south of the main office, and had consisted of 1,000 feet of drifting, and crosscutting also.
Development would still continue when the company had officially constructed it's 10 stamp milling facility. Ore from this mine is trammed from the adit, and dumped into the crushing facility, from which it passes into rolls, and over trommels. Much of the fine product is then place through a classifier, while the course material goes to a Hartz Jig. Tailings from the Jig are then passed through the 10 stamp milling facility, and make their way to the classifier. As the product passes through the classifier it makes it's way to a Wiilfey, Deister Table, and Deister Slimer. Company officials also had place a tube mill in order to re-crush the ore that comes from this mine. Power to the mine, and mill is commonly considered to have been electrically operated by the Cobalt Power Company.
Development on the Colonial Mine was mainly being confined to the adit level, and the 140 foot winze shaft. Hoisting within this time period was mainly being taken from the 125 foot level of this mining operations. It was rather reported that the 125 foot level became opened up by a west drift for a distance of 300 feet, and another drift known as the east had been driven for 350 feet. A crosscut was also started when it had reach a distance of 350 feet to the south, and another southwest crosscut became opened for a distance of 300 feet north-east, and 125 feet south west on the east drift Far more expanding continued when the company had also sunk a winze to the depth of 70 feet on east drift. As this occurred there was also a level establish on the bottom of this shaft, and was opened for a distance of 200 feet by a drift. The whole entire 10 stamp milling facility also had its own daily production rate of 25 tonnes of ore.
A small amount of development work had been achieved by the Colonial Silver Mines, :Limited within this time period. It was rather at this time when stopes were being prepared in order to keep up with the production of the 10 stamp mill. Nothing else had taken place during this time period of operating the Colonial Silver Mine Site.
The whole entire 10 stamp mill was shortly after lease to the Right of Way Mining, Company, and had treated its ore for the last seven months. For the most part it was reported that a small amount of work was being confined to the 350 foot level. Nothing else had taken place at this mine site prior to the company leasing it's milling facility.
More explorations continued when the Colonial Silver Mines, Limited had operated one drill for the first seven months. Much of the company's milling facility was still being leased to the Right of Way Mining, Company, when it was closed on September, 15.. No other development occurred when all mining operations became suspended by this company.
