Barksdale Continues to Delineate the Copper Porphyry System at Sunnyside, and Provides a Drilling and Results Update - Connecting the Upper and Lower Porphyry
Barksdale’s weak step-out holes dilute high-grade narratives as large future drill plans cannot offset today’s sub-economic copper intercepts.
Barksdale Resources Corp. (BRO) released assay results from 10 reverse-circulation holes (SUN26-005R to SUN26-014R) at its Sunnyside copper-porphyry project. The data highlights an outward geochemical zonation pattern, transitioning from proximal copper-silver to distal manganese-silver-zinc-lead deposits. The company also announced plans for a 15,420-meter diamond drill program scheduled for Fall 2026.
Key intercepts from the recent drilling include: - SUN26-013R: 0.3% Cu over 77.7 m, including 1.93% Cu over 7.6 m - SUN26-010R: 0.32% Cu over 12.2 m - SUN26-011R: 0.3% Cu over 4.6 m - SUN26-007R: 2.0 g/t Ag over 182.88 m - SUN26-012R: 4.59 g/t Ag over 91.44 m, including 36.58 m at 8.77 g/t Ag - SUN26-009R: 1.62 g/t Ag and 0.058 g/t Au over 111.25 m
Barksdale Resources Corp. is nearing the completion of a 25,000-foot reverse-circulation program, a requirement to increase its ownership stake in the deposit to 67.5%.
Barksdale Resources Corp. (BRO) saw its stock price rise from approximately $0.20 to $0.53 following discovery holes in May 2026. The price has since retreated to $0.23, suggesting the market had already priced in a high probability of follow-up success.
The recent step-out results are materially weaker than the discovery holes and do not confirm a large, economically viable porphyry system. These results dilute the thesis and increase the risk that the earlier high-grade hits were localized. For a junior explorer with no revenue, a discovery hole is critical; failing to repeat it is a material negative.
The company has announced a 15,420-meter diamond drill program, which serves as a future catalyst but cannot offset the poor near-term assay news.
Barksdale Resources Corp. (BRO) is a junior explorer that owns a 51% stake in the Sunnyside copper-porphyry project in Arizona, which sits adjacent to South32’s Hermosa property. The company is currently earning in to a 67.5% interest in Sunnyside. Barksdale also holds the San Javier copper-gold project in Mexico, which has a preliminary economic assessment, along with several early-stage porphyry targets in Arizona. The company’s capital structure includes 225.4 million shares outstanding, 95.2 million warrants, and $4.5 million in convertible debt.
