Silver Dollar Samples Up to 2,753 g/t AgEq in Underground Sampling Campaign at its La Joya Silver Project
Executive Summary
- Silver Dollar reported high‑grade underground channel sample assays from historic La Embotelladora workings at La Joya, including a standout intercept of 2,753 g/t AgEq over 0.4 m (Sample R‑300).
- The results support the Company’s strategic shift from open‑pit to underground mining by confirming localized high‑grade mineralization within ENE and NNE structural zones.
- Preliminary numerical modeling of historic drillhole data has identified additional prospective E‑W trends, guiding future exploration targeting.
Key Details
- Sample Intercepts:
- R‑300 – 2,753 g/t AgEq (0.4 m) – highest grade reported.
- R‑291 – 328 g/t AgEq (0.4 m).
-
Additional samples ranged from 1 g/t to 244 g/t AgEq over widths of 0.26–1.1 m (see Table 1 for full list).
-
Assay Methodology: Samples analyzed by ActLabs (ISO 9001:2015) using fire assay with AA for Au, ICP‑OES for Ag and 34 other elements; QA/QC included certified reference and blank controls.
-
AgEq Calculation Assumptions:
- Metal prices: Au $1,750/oz, Ag $22/oz, Pb $1.25/lb, Zn $1.50/lb, Cu $4.30/lb.
-
Recoveries: Au 66%, Ag 93%, Pb 87%, Zn 84%, Cu 70% (based on comparable regional mines).
-
Geologic Modeling: Preliminary numerical model trended existing drillhole assays along emerging E‑W structural trends; ongoing work will incorporate NNE trend and stratigraphic‑structural intersections to refine underground potential.
-
Strategic Implication: Results bolster the Company’s plan to transition La Joya from an open‑pit to an underground project, focusing future drilling on identified high‑grade zones and underground mining methods.

“With silver, copper, and gold prices all reaching record highs this year, it's an opportune time to re‑conceptualize La Joya from a new underground perspective,” said Greg Lytle, President & CEO.
“The goal of our geological modeling is to assess La Joya's underground potential … and identify high‑priority exploration targets to add value to the Project.”
