Thirteen Mineralization Horizons Intercepted At Sunnyside Exploration Project

VANCOUVER – Barksdale Resources Corp. reported on the SUN-003 drill hole, completed as part of the ongoing Phase I drill program at the Sunnyside copper-lead-zinc-silver exploration project in Arizona. Barksdale has intercepted multiple intervals of carbonate replacement style mineralization (CRD) at Sunnyside, extending the footprint of previously known mineralization approximately 90m to the northeast of historic drilling. Additional assay results are expected from the lower portion of SUN-003 soon.

Rick Trotman, President and CEO, said, “We’re excited to with the initial assay results from the Boundary Zone CRD, which show promising signs of a significant mineralizing system, that includes high grade copper from drill hole SUN-003. These results are particularly impressive given the intersections are characterized by stratiform mineralization, which typically occurs peripheral to a higher-grade feeder structure. In addition to returning significant assays, SUN-003 has bolstered our geologic model, providing a refined vector to the feeder structure which is now being drilled with SUN-004.”

SUN-003 is a vertical hole collared 2m from historic hole TCH-2 and was drilled to a total depth of 1,652. It drifted slightly to the north-northeast and intersected the top of the Paleozoic carbonate rocks at 1,239m depth, approximately 65m to the north and 80m deeper than discovery hole TCH-2. This confirms the general dip of the carbonate stratigraphy to be approximately 35 degrees to the north.

Twelve distinct horizons of strata-bound sulfide mineralization were intersected, which correlate with intercepts of historic hole TCH-2, located approximately 65m to the southwest, as measured from the top of the carbonate sequence, and roughly 95m distant at the bottom of SUN-003. TCH-2 displays intense calc-silicate alteration (i.e. garnet and epidote, with frequent quartz veins), suggesting a closer proximity to a heat and fluid source. Based on mineral assemblages present in SUN-003 and weak calc-silicate alteration seen, it is interpreted to be distal to the mineralizing feeder structure/intrusion source.

SUN-003 encountered the Concha, Scherrer and Epitaph Formations within the carbonate sequence, with mineralized horizons present in all three units. The Concha Formation contained two zones of disseminated polymetallic mineralization (Cu, Ag, Pb, Zn) which was hosted by favorable porous “dirty” limestones. Calc-silicate alteration was weak and included minor garnet (Ca/Fe), diopside, saponite, smectite, epidote, chlorite, and actinolite.

Below the Concha, the Scherrer Formation, which is well-correlated across the region, contains distinct intercalated marker beds of sandstone beds within the limestone unit. Within the Scherrer Formation SUN-003 intersected eight zones of polymetallic mineralization (Cu, Ag, Pb, Zn) that contained weak calc-silicate alteration including garnet (both Mn/Al and Ca/Fe), diopside, smectite, saponite, epidote, chlorite, actinolite, and irregular veinlets of pink calcite. Mineralization is stratigraphically controlled and commonly forms ‘patchy’ textures.

Drilling on SUN-003 was completed using PQ and HQ size diamond drill core. The core was logged by experienced geologists engaged by the Company. Drill holes are logged and marked for sampling prior to being sawn in half using a diamond blade saw, with one half of the sawn core being placed in a cloth sample bag, with a unique sample tag, while the second half was returned to the core box for storage on site.
