Barksdale Intercepts Copper-Rich CRD Sulfide Mineralization

In This Article:

Vancouver, British Columbia--(Newsfile Corp. - December 12, 2024) - Barksdale Resources Corp. (TSXV: BRO) (OTCQX: BRKCF) ("Barksdale" or the "Company") is pleased to announce that its ongoing exploration drilling program at its Sunnyside project (the "Sunnyside Project") in Arizona has intercepted significant base metal sulfide mineralization at depth. Mineralization is best described by Barksdale's geologists as carbonate replacement deposit ("CRD") style, and the mineralogy of the sulfide assemblage includes copper-rich phases, a possible indication of proximity to a porphyry source.

Rick Trotman, President and CEO of Barksdale comments, "We are thrilled that the top of the Paleozoic carbonate section is highly altered and has already given us a great ~10-meter intersection of copper-dominant semi-massive sulfides. We are confident in our geologic model and are continuing the hole to depth. It is exciting to see what comes next as we get deeper into the carbonates."

Drill hole SUN24-002B (see Figures 3 and 4), still in progress, was designed to test multiple targets, including known near surface copper-silver mineralization as well as deep extensions of massive to semi-massive lead-zinc-silver-copper CRD mineralization found elsewhere in the district including the nearby Taylor deposit, currently being developed by Australian mining company South32.

Thus far drilling has encountered approximately 93m (305ft) of intensely altered and variably mineralized Triassic-Jurassic volcaniclastic tuffs and breccias, that overlie intensely altered and mineralized carbonate rocks that are typically converted to silicified marble and calc-silicate skarn. The unconformable contact between the volcanic rocks and underlying carbonate units occurs at a down hole depth of 1,305m (4,281ft). Given the intensity of alteration and overprinting mineralization, the protolith carbonate stratigraphic units are difficult to ascertain because none of their original characteristics have been preserved.

Mineralization within altered volcanic and carbonate lithologies from 1,265 to 1,358m (4,150ft to 4,455ft) is comprised of intervals of semi-massive to stockwork textured sulfide mineralization containing up to 50% sulfide composed of coarse grained, chalcopyrite and galena with accessory sphalerite and chalcocite. Over a 9.75m (32ft) interval of semi-massive sulfides, from 1,348-1,358m (4,423-4,455ft), Barksdale's geologists believe that early-stage calcite veins were removed leaving a dense network of open spaces that were subsequently filled by coarse-grained base metal sulfides (see Figures 1 and 2).
