Stroud Resources Discovers New Silver Vein System at its Santo Domingo Silver Project, Jalisco, Mexico
TORONTO, May 09, 2023 (GLOBE NEWSWIRE) -- Stroud Resources Ltd. (TSXV: SDR) (“Stroud” or the “Company”) is pleased to provide a summary of its 2021-2022 drilling program, completed at its Santo Domingo Silver Property (“Santo Domingo” or the “Property”), located in the municipality of Hostotipaquillo, State of Jalisco, Mexico.
The 2021-2022 exploration drilling program consisted of approximately 9,936 m in 32 diamond drill holes (Table 1) and selected results from this drilling are provided in Table 2. The drilling program was designed to explore the extent of known epithermal vein-hosted silver mineralization on the Property and to begin to define additional silver-mineralized zones and vein systems which were anticipated to run parallel to the existing La Raya and Guadalupe silver vein systems. To date, the Santo Domingo Project has approximately 85 drill holes totalling 18,184 metres (Table 1).
Highlights:
- Discovery of third silver-vein system (Zopilote Zone) parallel to the Guadalupe and La Raya zones (Figure 1).
- SD-21-49: 625 g/t AgEq1 over 1.55 m (Guadalupe East Zone).
- SD-21-74: 680 g/t AgEq over 1.65 m (Guadalupe East Zone).
- SD-21-50: 230 g/t AgEq over 10.35 m (La Raya Zone).
- SD-21-71: 159 g/t AgEq over 36.80 m (La Raya Zone).
- SD-21-75: 152 g/t AgEq over 34.70 m (La Raya Zone).
- SD-21-52: 196 g/t AgEq over 15.10 m and 233 g/t AgEq over 6.45 m (La Raya Zone).
- SD-21-58: 173 g/t AgEq over 1.05 m (Zopilote Zone).
- SD-21-81: 147 g/t AgEq over 32.15 m (Zopilote Zone).
(1AgEq is calculated using a silver to gold ratio of 75:1, US$1,500/oz gold, US$20/oz silver, and recoveries of 100%.)
Figure 1 shows the new Zopilote vein system that is west and parallel to the La Raya and Guadelupe zones. The La Raya vein system is approximately 35 m wide by 300 m down-dip and over 700 m along strike. The Guadalupe vein system is typically 15 to 30 m wide.
Hostotipaquillo Region, Mexico
The Hostotipaquillo region has seen extensive drilling over the last three years. In particular, GoGold Resources Inc. (“GoGold”) has been drilling their Los Ricos South Project of which their Jamaica II property is adjacent to Stroud’s Santo Domingo Silver Property.
GoGold’s Los Ricos South Project has a mineral resource estimate containing Measured & Indicated Mineral Resources of 10.0M tonnes containing 63.7M ounces AgEq grading 199 g/t AgEq and an Inferred Mineral Resource of 3.3M tonnes containing 19.9M ounces AgEq grading 190 g/t AgEq (see GoGold news release dated July 29, 2020).
The Company’s NI 43-101 Mineral Resource Estimate and Technical Report on the Santo Domingo Property was issued on November 20, 2017. It comprises Measured & Indicated Resources of 6.0M tonnes containing 25.7M ounces AgEq grading 134 g/t AgEq and an Inferred Mineral Resource of 3.4M tonnes containing 13.3M ounces AgEq grading 120 g/t AgEq. The Mineral Resource Estimate was calculated using a cut-off grade of 45 g/t AgEq over a three-metre true width and a gold-silver ratio of 72:1 Continuity of mineralization was established by drilling on 50 metre centres and using a specific gravity of 2.65.

Drill Core Assay Results
Geological modelling of the Santo Domingo Silver Project identified additional silver and base metal mineralized zones running parallel to the previously announced Mineral Resource Estimate on the La Raya Silver Vein System.
Focus of the 2021 drilling campaign was to confirm the geological and mineral resource model for the La Raya Silver Deposit, as well as deepen exploration drilling to test expected mineralization of the La Raya vein beyond where historical Spanish miners were active. The 2021 drilling campaign confirmed the extension and geological interpretation of the La Raya and Guadalupe vein systems and identified a new silver-vein system to the west, named the Zopilote Zone.
The 2022 drilling campaign focused on the newly discovered Zopilote silver-mineralized zone, primarily beginning to test the extension, continuity and interpretation of the Zopilote vein system. The location of drill hole collars was limited by the previously approved drilling permit and its planned drill pads which had not accounted for the discovery of the new Zopilote Zone.
