Barksdale Resources (TSXV:BRO)(OTCQX:BRKCF) has reported the interception of significant base metal sulfide mineralization at its ongoing exploration drilling program at the Sunnyside Project in Arizona. The discovery, identified as carbonate replacement deposit (CRD) style mineralization, contains copper-rich sulfide phases. Company geologists believe this may indicate proximity to a porphyry source.
The drill hole, designated as SUN24-002B, is part of a broader program targeting both near-surface copper-silver deposits and deeper extensions of lead-zinc-silver-copper CRD mineralization. The region is known for hosting similar deposits, including the nearby Taylor deposit, which is being developed by South32, an Australian mining company.
Drilling Progress and Mineralization Details
Drill hole SUN24-002B has encountered a 93-meter section of intensely altered and variably mineralized Triassic-Jurassic volcaniclastic tuffs and breccias. These volcanic rocks overlie highly altered carbonate lithologies, converted into silicified marble and calc-silicate skarn. The unconformable contact between volcanic units and carbonate rocks was identified at a down-hole depth of 1,305 meters (4,281 feet).
The mineralized section extends between 1,265 meters and 1,358 meters (4,150 feet to 4,455 feet), containing semi-massive to stockwork sulfide mineralization. Geologists report up to 50% sulfide content within this zone. The sulfide assemblage includes coarse-grained chalcopyrite, galena, sphalerite, and chalcocite. A significant interval of mineralization measuring 9.75 meters (32 feet) from 1,348 meters to 1,358 meters (4,423 feet to 4,455 feet) showed dense sulfide networks. These networks formed after calcite veins dissolved, creating open spaces filled by base metal sulfides.
As of the latest update, drilling has reached 1,370 meters (4,492 feet) and remains ongoing. The company anticipates encountering additional mineralized zones deeper within the carbonate stratigraphy. Barksdale emphasizes that while the visual observations of mineralization are encouraging, the final significance of the results will not be confirmed until laboratory assays are completed. Samples for testing are currently being prepared and will be sent to ALS Global’s laboratory in Tucson, Arizona.
Barksdale Resources is a base metal exploration company focused on acquiring and developing high-potential projects in North America. The company’s primary projects include the Sunnyside copper-zinc-lead-silver project and the San Antonio copper project, both located in the Patagonia mining district of southern Arizona. Additionally, Barksdale is advancing the San Javier copper-gold project in central Sonora, Mexico.
Barksdale’s latest findings highlight the potential for significant CRD mineralization at the Sunnyside Project. While the reported copper-rich sulfides are encouraging, further drilling and assay results will provide clarity on the discovery’s scale and economic viability. The company’s exploration efforts continue to focus on defining the resource potential within this historically mineral-rich region.
