Channel sampling of the Candy Vein projection returned assays of 162 grams per tonne (g/t) silver equivalent (AgEq) over 12.48m within an oxidation zone over 100m wide. Mineralization appears to be widely disseminated, with strong iron oxidation and manganese pervasive in the zone and locally concentrated along fractures of multiple orientations. Trace concentrations of galena have been identified within the oxide zone. Outcrop is only partially exposed along an old road cut, and in small pits. Three areas were contiguously channel sampled as if they were trenches, with average assays as follows.

TRENCH	INTERVAL m	Au g/t	Ag g/t	Pb %	Zn %	AgEq g/t
NOR-Z-08	12.48	0.02	39	0.39	2.28	162
NOR-Z-09	4.27	0.01	27	0.13	0.76	68
NOR-Z-10	2.3	0.01	46	0.12	0.43	72

Table 1: North Canyon Channel sample averages.

Silver equivalent is calculated using the following metal prices in USD: Au $1,750/oz, Ag $22/oz, Pb $1.25/lb, Zn $1.50/lb. Recoveries of Au 66%, Ag 93%, Pb 87%, Zn 84% historically reported from Pan American Silver's La Colorada mine have been used in the AgEq calculation, and are assumed to be comparable to anticipated recoveries at Nora.

Procedure, quality assurance/quality control and data verification:

All rock samples were collected, described, photographed, and bagged on-site. The samples were delivered by Silver Dollar staff to ActLabs in Zacatecas, Mexico for analysis. ActLabs is ISO 9001:2015 certified. Soil samples were screened to -80 mesh at the lab, prior to analysis. Gold is analyzed by a 30g Fire Assay with AA (atomic absorption spectroscopy) finish, then gravimetric finish if greater than 10ppm Gold. Silver and 34 other elements were analyzed using a four-acid digestion with an ICP-OES (Inductively Coupled Plasma Optical Emission spectroscopy) finish. Silver, lead, zinc, and copper over limits were re-assayed using an ore-grade four-acid digestion with ICP-AES (Inductively coupled plasma atomic emission spectroscopy) finish. Control samples comprising certified reference samples and blank samples were systematically inserted into the sample stream and analyzed as part of the Company's quality assurance and quality control protocol.

"We are encouraged by the discovery of the most widespread mineralization found to date on the Nora Property," said Greg Lytle, President of Silver Dollar. "We have mobilized a crew to begin follow-up trenching, sampling and detailed mapping of the North Canyon Zone. The objective is to expand on and gain a better understanding of this new zone of disseminated mineralization."

The drill permit Silver Dollar received is valid for three years. It allows for the repair of access roads and the building of up to 18 drill pads on the Property. The Company expects to provide a detailed drilling plan when priority targets have been identified and fully delineated.

About the Nora Property:

Silver Dollar acquired a 100% interest in the Nora Ag-Au property (the "Property") from Canasil Resources, subject to a 2% net smelter returns royalty (See news release of February 8, 2024 ).

Located in the Eastern Sierra Madre sub-province in the transition to the high plateau of Mexico, the Property lies centrally within the "Silver Trend" that runs from the northwest to the southeast through Durango State (See location map ). Significant deposits in the region include Endeavour Silver's Guanaceví mine and Fresnillo's San Julián mine on-trend to the northwest, with Endeavour Silver's Pitarrilla project approximately 50 kilometers (km) to the east. Pitarrilla is one of the largest undeveloped silver deposits in the world and was discovered by Perry Durning and Frank (Bud) Hillemeyer, Silver Dollar's technical advisors.

The Property is located approximately 200 km north-northwest of the city of Durango, with excellent year-round access via Federal highway, paved road, and local dirt roads. Local infrastructure is available in the towns of Tepehuanes and Santa Maria del Oro and the city of Santiago Papasquiaro, all within 50km of the Property.

Dale Moore, P.Geo., an independent Qualified Person (QP) as defined in National Instrument 43-101, has reviewed and approved the technical contents of this news release on behalf of the Company. The QP and the Company have not completed sufficient work to verify the information on the Nora property, particularly regarding historical exploration, neighbouring companies, and government geological work.
