Carolina Rush (TSXV:RUSH) has recommenced drilling operations at its Brewer Gold-Copper Project in South Carolina. This move follows the completion and analysis of the first seven holes from the Phase IV drilling program. The renewed drilling efforts aim to further explore and delineate the mineralized zones within the property, with a particular focus on the recently identified Tanyard Breccia Zone.
Focus on the Tanyard Breccia Zone
The current phase of drilling concentrates on the Tanyard Breccia Zone, a new discovery located to the south of the historic Brewer Mine. This zone was highlighted in a news release by the company on February 28, 2024. Initial assay results from the area have confirmed the presence of a mineralized breccia body, characterized by significant gold-copper mineralization. This mineralization is hosted within a zone of intense quartz-pyrophyllite alteration, a geological environment typically associated with precious metal deposits.
Higher grade gold concentrations have been identified within discrete zones of highly silicified, pyritic breccia. The company has planned an additional four drill holes in the Tanyard area to target concealed mineralization beneath the maar sedimentary sequence. These new holes will also seek to extend the high-grade gold-telluride mineralization encountered in a previous drill hole (hole 21), which reported a significant intersection of 2.5 meters at 169 grams per ton (g/t) of gold.
Extension of Historic Drill Hole B21C-016
In addition to the new drill holes in the Tanyard Breccia Zone, Carolina Rush has announced plans to deepen a previously drilled hole (B21C-016) located in the northwest part of the property. This hole, which was initially drilled to a depth of 380 meters, is situated approximately 500 meters northwest of the historic Brewer pit.
The decision to deepen this hole stems from the discovery of strong quartz-pyrophyllite alteration with gusano textures near the bottom of the initial drill. These features, coupled with elevated molybdenum levels, suggest the potential presence of a primary porphyry copper system. To explore this possibility, the company will extend the hole by an additional 200 meters, bringing its total depth to nearly 600 meters. The results from this extended drilling are anticipated to provide further insights into the property’s mineral potential.
Recent Drill Results
The company has also released new results from two recent drill holes, B24C-031 and B24C-032. These holes confirmed the presence of the Tanyard Breccia, although they reported low gold values from the periphery of the structure. Despite the lower gold content, the confirmation of the breccia body’s presence is seen as a positive indicator for the ongoing exploration efforts.
Samples, typically 1.5 meters in length, were sawn in half, with one-half sent for analysis and the other half retained for future reference. The samples were sent to ALS Laboratory in Twin Falls, Idaho, where they underwent drying, crushing, and pulverization before being analyzed for gold content using fire assay methods with atomic absorption (AA) finish. For samples containing greater than 10.0 g/t gold, a gravimetric finish was applied. Multielement analyses were conducted using ICP-MS following a four-acid digestion, with specific methods employed for samples containing over 1.0% copper.
The resumption of drilling at the Brewer Gold-Copper Project marks a significant step in Carolina Rush’s ongoing exploration efforts in South Carolina. With a focus on the newly discovered Tanyard Breccia Zone and the potential extension of mineralization in other parts of the property, the company is poised to further understand the mineral potential of this historically significant mining area. As the drilling progresses, Carolina Rush anticipates gaining deeper insights that could shape the future development of the Brewer project.
Carolina Rush (TSXV:RUSH) has provided new results from its recent drilling program at the Brewer Gold-Copper Project in Chesterfield County, South Carolina. The program, conducted between October 2023 and January 2024, consisted of eight core holes totalling 2,022 meters.
Layton Croft, President and CEO, commented in a press release: “Our recent drill program had three objectives: i) To define and extend the mineralization beneath the former Brewer gold mine; ii) To follow up on newly discovered mineralization in the southern Tanyard zone; and iii) To test a geophysical target ~350 meters west of the former mine. We achieved all three objectives and implemented the program as planned, which gives us 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.”
The most recent holes – numbered 18, 19 and 20 – accounted for 941 meters of the total program. These holes were directed eastward, testing the extension of the breccia-hosted gold and copper mineralization below the former Brewer open pit mine. Assay results from these holes have now been received and released by the company.
Four additional holes – numbered 21, 22, 23 and 25 – were drilled south of the former Brewer mine at the Tanyard target area. These holes totalled 809 meters in length. Samples from holes 21 and 22 have now been submitted for analysis at ALS Laboratories, while samples from 23, 24 and 25 are still being processed and prepared for shipment to the lab. Final assay results from all outstanding holes are expected within 4 to 5 weeks.
Carolina Rush also drilled one vertical hole (number 24), located approximately 350 meters west of the former Brewer mine. This hole was targeting a large geophysical anomaly identified through prior surveys.
The Brewer Project is located on a 397-hectare former mine property, just 17 kilometres from the operating Haile Gold Mine along the same mineralized trend. Carolina Rush Corporation holds exclusive rights to explore, lease and purchase the Brewer property. The company also recently signed agreements to explore historic gold mine sites in Randolph County, North Carolina.
Patrick Quigley, Senior Geologist and Exploration Manager, also commented: “Hole 21 was the first hole following up on Hole 15, the new southern gold-copper zone we discovered in 2021 (62.40 meters @ 1.03 g/t Au and 0.15% Cu from 44.60 meters). The photos below in Figure 3 highlight characteristics of the mineralized breccia in Hole 21, including intense sulfide replacement and notable concentrations of copper sulfides, which are very encouraging. This newly discovered southern Tanyard zone is located near surface and near the former mine, providing further testament to how under-explored the Brewer property is. We still have a lot to learn about this new zone, and we believe there is a lot of potential in this overlooked area.”
