Silver Dollar Resources

Investor Insight

Silver Dollar Resources is advancing its La Joya silver-copper-gold project in Mexico through a fully funded 3,500-meter diamond drilling program targeting deeper San Martin-type mineralization. Supported by extensive historical drilling, high-grade underground sampling and updated 3D geological modeling, the company is repositioning La Joya toward high-grade underground silver potential in the prolific Durango-Zacatecas silver belt.

Overview

Silver Dollar Resources (CSE:SLV,OTCQX:SLVDF,FSE:4YW) is a mineral exploration company focused on advancing silver, copper and gold projects in Mexico. The company’s primary asset is the La Joya silver-copper-gold project located within the prolific Durango-Zacatecas silver belt, one of the world’s most productive silver mining regions.

La Joya is an advanced exploration-stage property supported by more than 60,000 m of drilling across more than 200 drill holes. Historical exploration defined multiple mineralized zones, including the Main Mineralized Trend, Santo Niño and Coloradito deposits.

Earlier work by previous operators primarily evaluated La Joya’s open-pit potential, while Silver Dollar is now advancing a revised exploration model focused on targets outside the historic resource areas, proximal to the sides of the intrusive bodies, that share similarities with the style of mineralization found at the nearby San Martin mine owned by Grupo Mexico.

The company’s 2026 exploration strategy integrates enhanced modelling of known high-grade mineralization, detailed underground and surface mapping and sampling, and the re-logging and sampling of select historical drill core. Through these efforts, Silver Dollar is gaining a better understanding of La Joya’s mineralization and its controls, which have guided target development for the 2026 drilling campaign.

Silver Dollar has commenced a fully funded 3,500-meter diamond drilling program at La Joya. The campaign is designed to test five priority underground targets, including Central Dyke, El Brazo, North Side, Road Zone and the El Puerto magnetic anomaly, which is interpreted to represent a buried intrusive source.

Key Projects

La Joya Silver-Gold-Copper Project

Optioned from First Majestic Silver in June 2020, when silver was US$17.50 per ounce, Silver Dollar completed the acquisition of a 100 percent interest in La Joya ahead of schedule in May 2023. First Majestic initially acquired the property in 2015 as part of its acquisition of SilverCrest Mines; however, no work was carried out on the property between 2015 and 2020.

SilverCrest acquired the Property in June 2010 and initiated geological mapping and sampling, which was followed by two phases of drilling that outlined multiple mineralized zones, the Main Mineralized Trend (MMT), Santo Niño and Coloradito deposits.

SilverCrest completed a mineral resource estimate (MRE) on the MMT and Santo Niño deposits, incorporating data from 56,849.33 metres of drilling across 173 drill holes (see Historical MRE Table). The MRE reportedly conformed to the CIM Definition Standards in effect at the time; however, a Qualified Person of Silver Dollar’s has not yet completed sufficient work to reclassify this historical resource, and the Company is not treating it as a current mineral resource. Independent data verification and an assessment of the mineral resource estimation methods are required to verify the historical mineral resource estimate.

The historical MRE formed the basis for National Instrument 43-101 Preliminary Economic Assessment Technical Report SilverCrest completed in December 2013, which focused on the base case economic estimates for a Starter Pit as the first stage of development at La Joya.

The deposits at La Joya are carbonate-hosted copper skarn deposits with associated silver and gold mineralization, similar in style to the adjacent San Martin mine, located approximately 25 km southeast in Zacatecas, Mexico.

Silver Dollar’s discovery of San Martin-type mineralization at La Joya (specifically at the Coloradito Intrusive, "El Brazo") provides evidence supporting the concept of deeper mineralization around the main intrusions at La Joya.

Both La Joya and San Martin are situated within the Cuesta del Cura Limestone and the overlying Indidura Formation, along the broadly defined San Luis-Tepehuanes fault system, commonly referred to as the Mexican Silver Belt. These intrusions are of the same age, similar in size and composition, and in both cases, mineralization is concentrated along the contact near the outer limit of skarn alteration surrounding the intrusion. Historically, the San Martin mine reportedly contained more than 300 million ounces of silver, with mineralization extending vertically for more than 850 meters. Drilling has indicated that mineralization remains open for an additional 400 meters below known intercepts, suggesting depths well beyond 1,200 meters (approximately 4,000 feet). This makes San Martin an ideal exploration model for targeting deeper mineralization at La Joya.

Silver Dollar’s 3,500-metre drilling program in progress has been developed to test several targets for deep San Martin-type mineralization below known mineralization or magnetic anomalies near the margins of the intrusive bodies. The initial 2026 drill targets include:

Central Dyke: Delineated over a strike length of 770 m with 134 of 170 samples (156 channel and 14 rock grab samples) returning assays >100 grams per tonne (g/t) silver equivalent (AgEq); including sample #161, taken in altered carbonate sediments proximal to the intrusive, that returned 3,823 g/t AgEq.

El Brazo: Situated approximately 1 km west of La Joya's Main Mineralized Trend (MMT), is a carbonate-hosted mineralized system exhibiting characteristics consistent with the San Martin carbonate replacement deposit (CRD) model. Drill hole NOR-22-013 intersected 232 g/t AgEq over 19.35 m, including a higher-grade interval of 535 g/t AgEq (420 g/t silver, 0.41 g/t gold, 0.05 percent copper, 1.97 percent lead, and 3.9 percent zinc) over 5.0 m. Silver Dollar's El Brazo discovery not only confirms the presence of high-grade CRD mineralization but also highlights the potential to expand future mineral resource estimates at La Joya by including lead and zinc credits, which were notably absent from the historical calculations.

North Side: With historic hole LB96-04 intersecting results of 694 g/t AgEq over 8.6 m at a depth of 401 m, this deep high-grade mineralization identifies a "San Martin" type target, along strike and to the north of the MMT. This target is below and beyond the depth of previous drilling and remains open in all directions.

Road Zone: Located just to the northwest of the MMT, is a blind gold-rich target, originally intersected at 126 m in hole NOR-21-004 (that deviated while testing a deeper North Side target). This structure is identified by the presence of rhodonite with fine-grained pyrite-chalcopyrite that assayed 1,099 g/t AgEq over 3 m. Subsequent drilling intersected similar mineralization in holes NOR-22-010 (204 g/t AgEq over 2.09 m) and NOR-22-017 (700 g/t AgEq over 1.87 m) over a strike length of 190 m.
