In January 2020, Carolina Rush (formerly Pancontinental Resources) won the exclusive right to explore and purchase the former Brewer Gold Mine property, with an option period through 2030.
Between 1987-1995, Brewer produced 178,000 ounces of oxide gold from open pits that extended to 65-meter depths, where gold (Au) and copper (Cu) sulphides were exposed but could not be processed by the oxide heap leach operation.
Located in Chesterfield County, South Carolina, Brewer is approximately 17 kilometers along trend from the producing Haile Gold Mine. Brewer is a large, epithermal, high sulphidation gold-copper system driven by a sub-volcanic intrusive, possibly connected to a copper-gold porphyry system at depth (Schmidt, R.G., 1978, The Potential for Porphyry Copper-Molybdenum Deposits in the Eastern United States, U.S. Geological Survey).
Rediscovering the Former Brewer Gold Mine in South Carolina
As of January 31, 2024, Rush has drilled more than 11,000 meters of: diamond core, rotary air blast (RAB), and sonic drill hole samples, with the latest drill program (October 2023 – January 2024) adding 8 core holes for a total of 2,000 meters. Drill results to date have been very encouraging with the latest drill program having three main objectives
To define and extend the mineralization beneath the former gold mine;
To follow up on newly discovered mineralization in the southern Tanyard zone; and
TO test a geophysical target ~ 350 meters west of the former mine.
Rush achieved all three objectives and implemented the program as planned, which provided useful new insights into the geometry and controls of Brewer’s gold-copper mineralization. Results have been received and reported for the first 3 holes. Initial visuals on pending holes are promising, and we anticipate more results in coming weeks.
Compelling Results to Date
Rush takes a data-driven approach to exploration, using historic and new geological, geochemical, mineralogical and geophysical data to target, discover and define new gold-copper mineralization. To date Rush has released results for 20 diamond core, 94 RAB, and 6 sonic drill holes at Brewer. True widths are not yet known.
Grade x Thickness (GT) values are a common way to measure the significance and future potential of early-stage drill programs. By taking core lengths multiplied by the gold + copper (gold equivalent, AuEq), grades, one can calculate GT values in terms of gram-meters. Paradigm Capital, a research-driven, independent, institutional equity investment dealer based in Toronto (www.paradigmcap.com), characterizes:
*Compositing parameters: Minimum grade = 0.3 g/t Au, Minimum width = 5m, Maximum consecutive waste allowed = 3.1m, Maximum total waste allowed = 9.1m
**Au_GxT Sum calculation includes all intervals meeting composite criteria for each drill hole, only most significant intervals listed in table
Summary of Best Intersections in Each Hole
Notes: *Reported intervals are drilled widths and do not represent true thicknesses. Holes ranked in terms of best GxT value (GxT = Au grade x thickness). Table shows reported intersections with a GxT value > 10 with new results highlighted in blue.
