By 1923, the No.2 shaft was officially being added towards this medium scale mining empire that was being engineered to about 81 feet below the ground. Some other smaller scale prospecting shafts we're also being put to the test when company officials had developed the No,3 shaft to about 59 feet and the No.4 shaft to about 120 feet. Another 125 feet of drifting was also being conducted on the No.2 shaft zone as some gold was being recovered from this area. Further surface drilling had soon indicated valuable ore resources within the Main No. 1 shaft which would end up deepening this mining section. Over 10,000 feet of core sample had soon sent company officials towards expanding the No.1 shaft to about 1,455 feet below the surface. All of this medium scale development had soon developed further mine levels that became situated on the mines 150, 275, 400, 525, 675, 825, 975, and the last level to become developed was establish on the mines 1,425 foot section. Lateral development from all eight levels had soon rose significantly as it had now contributed 19,715 feet of development towards this massive extraction business.
As development continued from the two shallow shaft operations, the company it self did not come across anything encouraging. The deepest of all the shallow shaft operation was only considered to have been sunken to a depth of 125 feet. It had also consisted of a small amount of lateral work that was known for totalling 600 feet, and a minor diamond drilling phase of 10,000 feet was also driven within this section. With not enough encouraging results the company had decided to further conduct another extensive diamond drilling program to uncover any more potential resources. Sure enough the company was once again going through its own exploration stages when it had discovered another ore-body. Much of this newly discovered ore-body soon had place new development procedures in 1936, as the company was now constructing a three compartment shaft operation. As development continued the newly engineered shaft was rapidly expanding when it was now reaching a depth of 52. Company officials from the Moneta Porcupine Mines would also place construction phases on a steel head-frame., and its very own processing plant. Within 1937, the whole entire head-frame was completed, and had included its very own 2 Canadian Ingersoll Rand Model XVHE-2, a 815 cubic foot compressor, with a 150 H.P motor, and a Canadian Ingersoll Rand Double Drum Hoist that was driven by a 75 H.P Motor.
As spring had slowly rolled in, the three compartment shaft operation was being further driven as it had reach 540 feet below the shaft collar in 1938. This newly developed shaft had also started to open up by four newly constructed levels that became cut and stationed on the mines 150, 275, 400, and 525. Development on the 150 foot level was also transforming this operation when it had been opened up by 488 feet of drifting, 263 feet of crosscutting, and 71 feet of raising. Even more development phase became conducted on the 275 foot level when it was opened up by 448 feet of drifting, 282 feet of crosscutting, and 166 feet of raising. The 400 foot level of this shaft operation was said to have been opened up by 472 feet of drifting, 232 feet of crosscutting, and 133 feet of raising. Almost all development on the 525 foot level was rather being opened up by 456 feet of drifting, 221 feet of crosscutting, and 126 feet of raising.
Within 1938, the Moneta Porcupine Mines Limited had also completed the construction phases of its newly developed 200 tonnes cyanide milling facility. Much of this whole entire construction phase was being aimed to increase its production from 150 tonnes to 200 tonnes of processed ore on a daily basis. As mill construction was still taking place the company, and its employees had soon deepened the shaft 956 feet. This whole entire shaft sinking phase would additionally open up new levels that became stationed on mines 650, 775, and 900 foot levels.
By 1941, the whole entire mining operation was now being owned by the Moneta Porcupine Mines Limited, who had owned 8 claims that were situated on 320 acres of land. In addition the company had started to further expand the vertical three compartment shaft to about 1,455 feet below the ground. The first level that was located at 150 feet, had totalled 1,398 feet of drifting, 301 feet of crosscutting, and 336 feet of raising. Another level that was found on the mines 275 foot level had totalled 936 feet of drifting, 398 feet of crosscutting, and 145 feet of raising. The third level that was established at 400 feet, had totalled 2,733 feet of drifting, 840 feet of crosscutting, and 147 feet of raising. Company officials had even started further production on the mines fourth level that was situated on the mines 525 foot section, and had 1,757 feet of drifting, 315 feet of crosscutting, and 220 feet of raising. All development on the fifth mine level was soon carried out on the mines 675 foot level, and had 1,430 feet of drifting, 204 feet of crosscutting, and 322 feet of raising. Further development by the company and its employees was also achieved on the mine's 825 foot level, and had consisted of 820 feet of drifting, 150 feet of crosscutting, and 92 feet of raising. Another major development phase was also being conducted on the mines 975 foot level, and would end up developing this mine further by adding 3,021 feet of drifting, 291 feet crosscutting, and 145 feet of raising. Company officials who had owned the Moneta Gold Mine had even started on developing two stations that were to be establish on the mines 1,125 foot section and its 1,275 foot section. Below the two stations, the company had now further started to commence construction on the next production level that was situated on the mines 1,425 foot level. Development on this section was started by further expanding the drift to about 3,327 feet, while expanding the crosscut sections to about 247 feet. No further raising was done on this level at the time as it was just being opened up by the newly establish company who was on a mission to find more gold.
Besides further developing this mine, the company was on another move when it had started on a small diamond drilling phase on the surface and underground levels. All of this was said to have consisted of five surface diamond drilling hole that totalled 1260 feet, while another 56 underground diamond drill holes had totalled 12,306 feet. The Moneta Porcupine Mines Limited had also obtain 60,632 tons of ore that was hoisted from the underground workings. All of this ore that was hoisted was made up of 58,800 tons from the stopes, 385 tons from taking down backs, and 1,447 tons from development. No further production or development was said to have commenced by the company during that year.
In 1943, the Moneta Porcupine Mines Limited had start to further develop this mining site by hoisting and milling all the extracted that came from the mine. Production during that year had processed a total of 14,101 tons of ore that came from the underground stopes. Almost all development was being focused on two levels that were known to be located on the mines 525, and 1,425 foot level. Another 51 feet of drifting was drilled and blasted on the 525 foot level, and the last level had achieved 6 feet of drifting during that year. Further diamond drilling was also being conducted that had drilled two surface diamond drill holes to about 160 feet into the ground. Another small scale drilling phase of four underground diamond drill holes was also achieved below ground and had totalled 4,053 feet of core sample to be examined. After not producing enough tonnage, the company and its employees had decided to fold from this production and allowed the shaft to flood in with water.
