					o	Hole was lost at the top of the target zone, follow-up drilling planned

Alex Davidson, Vice President, Exploration commented: "We are very pleased with the assay results from the Vortex - Camel high-grade silver dominant trend. The drilling was designed to test the west dipping low angle structures responsible for brecciation that is allowing for the significant mineralization at Vortex. This new drilling not only adds significantly to the known high-grade silver mineralization by extending Vortex to the west and south, but also vertically ties together what were previously considered to be discrete zones of high-grade. Furthermore, the drilling contributes significantly to our understanding of how these low angle structures open exploration potential to the east of the current resource."

Holes 6001 and 6002 were designed to test continuity of more than 150 meters of spacing between holes drilled in 2023 and to test downdip extensions of Vortex. Both objectives were achieved in growing Vortex vertically as well as extending laterally, confirming the system continues to remain open in all directions and at depth.

Hole 6007 targeted the farthest western extension of the Vortex trend. The intercept from this hole extends mineralization past the current resource to the west by approximately 100 meters. Additionally, 6007 targeted a potential feeder zone for Vortex mineralization, based on a large area of native sulfur mapped near the surface above the target an indicator of a zone of high fluid flow. Unfortunately, the hole was lost in the top of the target zone where it intersected 1.5 meters of 950 g/t silver and 4.78 g/t gold. Follow up drilling is planned for 2024.

Hole 6000 was lost in a fault zone but not before encountering mineralization from 71 meters to over 300 meters at depth. The hole will be re-entered at a future date.

Assays are pending for the Brimstone high-grade trend (Holes 6003, 6004, 6009 – 6012).

About the 2024 Exploration Drill Program

The drill program is designed to improve continuity within the recently discovered high-grade silver trends (Vortex – Camel and Camel – Brimstone), extend mineralization along strike and at depth, and test new exhibiting potential for high-grade within and outside the currently known resource. Through this work the Company hopes to develop opportunities to mine higher-grade ore early in the mine plan, thereby enhancing the project's economics. The 2024 Drill Program, consists of a total of 8,500 meters of core drilling. The drilling is being conducted by Timberline Drilling Incorporated of Elko, NV. Assays are being completed by ALS Geochemistry of Reno, NV. The Company's Qualified Person is Alex Davidson, Vice President, Exploration.
