Gold mineralization was probably first discovered in the Atlanta Mine area during the 1860s. Yet, other than some underground mine maps and sections, few records remain of the exploration conducted prior to the Atlanta Mine being put into production during the mid-1970s.
From 1975 – 1985, the Atlanta Gold Mine produced 1.5 million tons of ore containing:
0.09 oz of gold/ton
1.25 oz of silver/ton
During the same time period, it recovered:
Gold Fields Resources (1990-1991)
The first extensive modern exploration program was conducted by Gold Fields Resources from 1990 to 1991 pursuant to an option from Bobcat Properties.
Gold Fields conducted extensive studies of the area, including:
- Geochemical sampling of soil, rock-chips and vegetation
- A broad suite of geophysical surveys
- Geologic mapping
- One Master’s thesis (LeBerge, 1995)
In addition, Gold Fields drilled 56,021 feet in 82 core and RC holes. The drilling included step-out holes that resulted in expanding the extent of the known mineralization.
The quality of Gold Fields’ historic data quality is good, but some of the data is missing. The core and cuttings remain in the mill building and are well preserved. Paper copies of the drill logs and geophysics data are also preserved in files. However, the Company has been unable to locate any originals or reproductions of Gold Fields’ geochemical surveys or geological maps.
Kinross Gold optioned the Atlanta Project from 1997 to 1998 during which time Kinross conducted the second extensive exploration program. While Kinross also compiled maps and conducted geochemical sampling, such efforts were undertaken primarily to corroborate Gold Fields’ historic results. Similarly, Kinross limited its geophysical investigations to re-interpreting the data previously collected by Gold Fields.
Kinross drilled an additional 54,225 feet in 80 RC holes. Using the historic data provided by Bobcat Properties and Gold Fields Resources, together with its own data, Kinross prepared a resource estimate using Datamine computer software.
The Kinross data is generally well preserved. Paper copies of the logs and assay certificates are in the Company’s files and much of the resource estimate is preserved in electronic data files.
Cordilleran Exploration briefly optioned the property in 2000. They drilled five RC holes totalling 2,785 feet before returning the property in 2001. Portions of the Cordex data have been acquired including some of the drill logs with assays and a regional geologic map.
