- SCR-044 intercepted 12.19 m averaging 11.22 g/t Au, including 6.09 m averaging 21.58 g/t Au
- SCD-008 intercepted 11.7 m averaging 0.92 g/t Au, including 4.55 m averaging 1.84 g/t Au
Three of the four new holes successfully tested the southeastern and northwest periphery of the higher-grade shoots:
- SCD-026 intercepted 8.4 m averaging 0.718 g/t Au
- SCD-027 intercepted 7.2 m averaging 0.601 g/t Au
- SCD-028 intercepted 6.0 m averaging 0.885 g/t Au
At the southeastern periphery, SCD-027 extended the shoot's lengths by approximately 50 meters whereas at the shoot’s northern periphery, SCD-028 intercepted three different mineralized intervals. SCD-028 is located approximately 30 meters north of where previously announced drill hole SCD-016 also intercepted several mineralized intervals including 11.25 meters averaging 1.08 g/t Au. Furthermore, the SCD-028 intercepts appear to be the western splay of the adjacent Guadalupe or
At the Guadalupe gold mineralized zone, located in the western region of the concession, scout drill hole SCD-029 intercepted 3.9 meters averaging 0.358 g/t Au, including 3.9 meters averaging 0.234 g/t Au. The drill hole investigates the northernmost area of the Guadalupe zone and is approximately 250 meters north of the previously announced SCR-030 which intercepted 22.86 meters averaging 0.725 g/t Au. Additional drill holes are planned to determine the potential for Guadalupe to increase the project’s gold mineralization.

- SCD-030 intercepted 9.3 m averaging 0.719 g/t Au
- SCD-031 intercepted 15 m averaging 0.503 g/t Au
At the southeastern end of the Veta de Oro gold mineralized zone, four core drill holes, SCD-032, SCD-033, SCD-034 and SCD-035, and two RC holes, SCR-156 and SCR-157, tested an area of vein stockwork and confirmed narrowing vein zone in the covered area between the Veta de Oro zone and the Abejas zone, located 500 meters to the south.
SCD-032 through SCD-035 were the final core drill holes of 2020 and are located directly south of drill hole SCD-015 which, as announced on

Japoneses Zone Infill Drilling
The following assay results are the final six of 33 RC holes drilled during the 2020 drill program. A total of 70 holes have been drilled within the Japoneses zone (which now includes Boluditos and Chinos NW zones) as the Company works to define the 1,300 meter long by 400 meter wide zone’s shallow oxide gold mineralization. These holes are intended to infill gaps in the drill pattern. Selected RC drill hole Intercepts from the Japoneses mineralized zone include SCR-151 with 27 meters averaging 0.694 g/t Au which is a wide addition to the zone’s near surface mineralization. A high-grade vein with a width of 3.05 meters averaging 3.355 g/t Au, which was intercepted within the 27-meter interval, is interpreted to be a section of the main Japoneses vein. Intersections in the Japoneses zone appear to have true widths approximately 15 percent less than reported as drill length intersections.

Quality Assurance/Quality Control (“QA/QC”) Measures and Analytical Procedures
Drill samples are collected with an airstream cyclone and passed into a splitter that divides each sample into quarters. The quartered samples are then bagged and sealed with identification. The sample group has blanks, standards and duplicates inserted into the sample stream.
Bureau Veritas (BV) collects the samples and transports them directly to the preparation laboratory in
No QA/QC issues were noted with the results received from the laboratory.
