Abstract The Brewer Gold Mine is situated within the Carolina Slate Belt of the Piedmont physiographic province approximately 1 km west of Jefferson, SC and 13 km northeast of the Haile Gold Mine, Kershaw, SC (Figure 1). Regionally, the mine is located about 80 km southeast of Charlotte, NC and 80 km northeast of Columbia, SC. The mine was discovered in 1828 and began as a placer operation. Butler (1985) provides a chronological history of production. Historic production was from four main pits that are, from largest to smallest, Brewer, Hartman, Hilford Cut, and Topaz. Minor underground workings were developed from these pits. Gold production occurred in various intervals with the last time period from 1934 to 1940. Pre-modern gold production is estimated at a minimum of 22,000 ounces. A number of companies have prospected and drilled at the Brewer including the USBM. Exploration drilling on the property (core and rotary) totals 44,026 ms. Approximately three-quarters of the drilling was performed by Nicor/Westmont/Brewer both in pre-production exploration drilling and development drilling while in production. In 1987, Westmont Mining Inc. formed the Brewer Gold Company and production began in mid-1987 as an open-pit, heap leach operation. The reserve base at the onset of mining was 5.1 million tons @ 0.042 opt Au (4.6 Mt @ 1.4 g/t). Mining continued from three different pits; Brewer, B6, and Northwest Trend (Figure 2) and ceased January 1993. A total of 5.66 million tons of ore was mined with 177,674 ounces of gold being recovered. Table

Abstract Renewed gold exploration in the Carolina slate belt of North and South Carolina that led to the discovery of the Ridgeway gold mine (#5 on Figure 1) by Amselco (now Kennecott) began at about the same time as the last Geological Society of America field trip to focus on southeastern metal deposits. That trip occurred in the fall of 1980 as part of the national GSA meeting in Atlanta, Georgia (Bell, Carpenter, and Feiss, 1980). On that trip at stop 8, Henry Bell described abundant hydrothermal alteration similar to the Haile and Brewer mines in an area with no known gold mines. He noted that auger cuttings from a hole drilled by the South Carolina Geological Survey in the 1960’s near stop 8 at Mount Rehovah church contained 0.06 ppm gold and 220 ppm copper in the upper 9 feet of rock and 10 ppm molybdenum from 30-40 feet. Because the values decreased with depth, the gold was attributed to surface enrichment (Bell, 1976). Samples collected by Bell (1976) of small drainage basins in the region contained up to 1000 ppm tin in heavy mineral concentrates that were also anomalous in gold, boron, lanthanum, niobium, beryllium, and copper (Figure 16 of Bell, Carpenter, and Feiss, 1980). Bell et al. (1980) stated “Geochemical data suggest that this region is on the periphery of an area having many of the ore-bearing characteristics of the Haile and Brewer mines” Stop 8 was only hundred’s of feet west of the present site of the

Abstract The Haile gold mine is located in southern Lancaster County, South Carolina, near the town of Kershaw. Gold was discovered at the site in 1827, and four periods of mining have yielded 360,000 ounces of gold. The mine is located between the past producing Ridgeway and Brewer mines that, when all are combined, constitute a significant amount of historical gold production in the southeastern United States. These mines are hosted within Neoproterozoic to lower Cambrian Carolina terrane rocks and are dominated by volcanic and epiclastic units that have experienced greenschist facies metamorphism. Saprolitic weathering is present in the near-surface portions of the deposit and is locally covered by Cretaceous-aged Coastal Plain sediments. The gold mineralization at the Haile mine is hosted within silicified meta-sediments containing fine-grained disseminated pyrite and pyrrhotite and is a replacement type-epithermal deposit. Re-Os ages from molybdenite associated with the mineralization indicate that the deposit formed shortly after major, arc-related volcanic activity. Haile currently has a measured and indicated resource of 4.03 million ounces at an average grade of 1.77 g/t Au with an additional inferred resource of 801,000 ounces at an average grade of 1.24 g/t Au. Included in the resource is a reserve of 2.02 million ounces of gold at an average grade of 2.06 g/t. Mine construction began in May 2015, and gold production is expected by the end of 2016. The construction cost is expected to be US$380 million. Ore will be extracted from eight open pits with mill extraction and the current mine life is 14 years.

Abstract First, this volume explores the Haile gold mine, which is located in southern Lancaster County, South Carolina. Gold was discovered at the site in 1827, and the mine is located between the past producing Ridgeway and Brewer mines that, when all are combined, constitute a significant amount of historical gold production in the southeastern United States. The second guide focuses on the geology and geomorphology of the Carolina Sandhills in Chesterfield County, South Carolina, an area in the updip portion of the U.S. Atlantic Coastal Plain province. The third guide provides a structural analysis of the Kiokee belt and its framing elements: Savannah River transect.
