Beyond the Headline
Barksdale announced on July 20, 2026, results from an additional 10 reverse circulation drill holes at Sunnyside. Copper and silver highlights reported in the release are as follows:
- 3% Cu over 77.7 m from 187.5 m hole depth, including 1.93% Cu over 7.6 m from 187.5 m in SUN26-013R
- 32% Cu over 12.2 m from 228.6 m hole depth in SUN26-010R
- 3% Cu over 4.6 m from 620 ft hole depth in SUN26-011R
- 0 g/t Ag over 182.88 m from 5 m hole depth in SUN26-007R
- 59 g/t Ag over 91.44 m from a depth of 15.2, including 36.58 m grading 8.77 g/t Ag from a depth of 18.3 m in SUN26-012R
- 62 g/t Ag and 0.058 g/t Au over 111.25 m from 189 m hole depth in SUN26-009R
The newly released results indicate that copper grades decrease to the east, transitioning into a zone of lower copper and higher zinc grades, which may suggest movement away from the high-grade copper-mineralized shell. Holes drilled to the northwest show declining copper grades with increasing silver, lead, zinc, and manganese credits.
The Company concluded that “Assay results from the recent holes define an outward zonation pattern from the high-grade copper of proximal Cu-Ag mineralization, to a transition zone of Cu-(Zn-Ag) mineralization to a distal zone of Mn-Ag-(Zn-Pb) mineralization, mirroring zonation patterns found in Large Copper Porphyry systems throughout the world.” (Figure 2)
The Company has engaged VRIFY Technology to refine and identify new mineralized targets on its Arizona properties using AI analysis and expects to release a preliminary target model from that work in early August. Further, Ellis Geophysical Consulting has been retained to review all geophysical surveys in hand and oversee an airborne ZTEM survey with possible follow-up targeted IP surveys on the Company’s Arizona properties.
