The Colosseum Gold Mine was a historic gold mine that still had gold deposits when the project stopped drilling in 1992. In March of 2021, investors bought the mine in hopes of drilling the remaining gold ore left in the area. One of the first things that happens when a company takes on a new project is the compilation and verification of the existing data. The data had to be shipped over from the old mine offices that were now closing. The data arrived in boxes completely unorganized and there was a mixture of paper maps and files with lists of drill holes coordinates and assay data. The 3 different companies that had worked in the Colosseum area had created 3 different mine grids to map out the mine and drilling activities. Most of the mapping was done before total stations and GPS units were readily available. The challenge and purpose of this Master’s Project was to use these 3 local mine grids to integrate them to real world coordinates and field verify the results. Once the real-world projection is integrated, the data originally mapped historically can be used digitally in different mapping software applications including Datamine Discover 3D and MapInfo Professional. The verification of the projection is critical in this project because the drill hole locations and gold ore deposits are not very big and miscalculating this projection can result in the loss millions of dollars. This project is still on-going and Colosseum Mine is still drilling for gold.
