AbstractIn March 2021, an Australian publicly listed company agreed to acquire the Colosseum Gold Mine, a past-producing precious metal property in San Bernadino County, California. GeoGRAFX Consulting LLC of Tucson, Arizona, was contracted to organize the existing data. The company received 122 boxes of files and maps for the Colosseum project. The data was generated from 1972 through 1993. The quality of the files and maps was degraded due to their age and storage conditions. GeoGRAFX compiled a verified digital project database of all obtained land status, geology, topography, drill hole, assay, and lithology data used in the resource evaluation from the files provided for the Colosseum project. Previous companies for the Colosseum Mine created three local mine grids between the early 1970s and 1987. The challenge and purpose of this Master’s Project was to use these three local mine grids to integrate with real-world coordinates, and field verify the results. The data verification checks performed internally by GeoGRAFX staff and external and independent reviews have resulted in sufficient validation of the entire historic database at the Colosseum Project. The company used the data to model the geology and calculate a Mineral Resource.
