Carolina Rush Intersects 74.5 meters of 1.1 g/t Au and 0.17% Cu, including 13.5 meters of 1.7 g/t Au and 0.68% Cu, at Brewer

Highlights:

• Hole 18 (B23C-018) intersected:
  • 74.50 meters of 1.1 g/t Au and 0.12% Cu from 166.50 meters depth,
  • including 11.50 meters of 3.1 g/t Au and 0.12% Cu from 168.00 meters,
  • and 13.50 meters of 1.7 g/t Au and 0.68% Cu from 203.09 meters (see Figure 1).
• Hole 19 (B23C-019) intersected:
  • 43.32 meters of 0.4 g/t Au from 336.18 meters depth,
  • including 5.61 meters of 1.2 g/t Au from 373.89 meters.

Patrick Quigley, Senior Geologist and Exploration Manager, stated: "Mineralization encountered in Hole 18 is one of the more significant intercepts reported at Brewer to date, confirming mineralization extends at least 115 meters below the former mine and remains open for extension in all directions. Noteworthy is a 6.7-meter zone of intense sulfide replacement within the breccia that averaged 1.02% copper and 1.9 g/t gold, indicating that discrete zones of higher-grade copper-gold mineralization persist at depth."

Layton Croft, President and CEO, stated: "It is useful to review our latest drill results within the context of information and analysis produced since we started exploring Brewer in 2020 (see Table 2). With only 19 holes, we have consistently reported exceptional drill results and demonstrated Brewer's big, exciting potential. What is needed most now is more drilling."

The first three holes of Carolina Rush's 2023-2024 drill program were designed to test the western, down-dip extension of the breccia-hosted gold-copper mineralization that was historically mined from surface to a maximum depth of 65 meters (see the November 20, 2023 news release). Results from Holes 18 and 19 continue to demonstrate that a broad zone of gold+/-copper mineralization exists beneath the former pit. Rush is the first company to systematically evaluate the underlying sulfide mineralization beneath the historic oxide mine. These new results provide a three-dimensional assessment of the 'Brewer breccia' that improves understanding of the geometry and controls on mineralization.

Hole 18, collared approximately 175 meters west of Hole 8 and drilled east at a -50 degree inclination, was designed to test the down-dip extension of breccia-hosted mineralization encountered in Hole 8, and it successfully extended the mineralized zone approximately 65 meters down-dip (see Figure 1). Due to the nature of mineralization in Hole 18, namely massive sulfides, this hole was left open to facilitate future downhole geophysical surveys that may allow for the detection of additional sulfide mineralization beyond Hole 18. Importantly, the dominant copper-bearing mineral identified in Hole 18 is chalcocite, a high-tenor copper sulfide mineral comprised of nearly 80% copper by weight. This validates the Company's prior observations at Brewer, confirming the transition to chalcocite below the near surface copper-enargite historically reported at Brewer.

Hole 19, collared approximately 250 meters west of Hole 5 and drilled east at a -45 degree inclination, was designed to test the down-dip extension of breccia-hosted mineralization encountered in Hole 5. In addition to intersecting breccia-hosted gold mineralization associated with Hole 5, Hole 19 also encountered discrete mineralized zones within the hanging wall of the Brewer breccia, indicating the presence of additional mineralized structures below the former mine.

Quality Assurance and Quality Control Statement

2023 exploration diamond core drilling was HQ and/or NQ size. The core was logged and marked for sampling and assaying by geologists contracted by Rush. Samples, typically 1.5 meters in length, were sawn in half using a diamond core saw and one-half of the core was placed in sample bags and tagged with unique sample numbers, while the remaining half was kept in the core box for storage. Each bagged core sample was shipped to ALS Laboratory in Twin Falls, ID where it was dried, crushed and pulverized to >80% passing -200 mesh. Gold was analyzed by fire assay (30 g) with an AA (atomic absorption) finish (method Au-AA23) with detection limits of 0.005 g/t gold. Samples containing greater than 10.0 g/t gold were analyzed by fire assay with a gravimetric finish (method Au-GRA21). Multielement analyses were analyzed with ICP-MS following a four-acid digestion (method ME-MS61) and samples containing >1.0% copper were analyzed via method Cu-OG62. Strict sampling and QA/QC protocols are followed, and assay integrity is monitored internally with a quality control program including the insertion of gold standards and blanks in the sample stream on a regular basis.
