BARKSDALE REPORTS FINAL ASSAYS FROM SUN-003

Barksdale Resources Corp. has provided assays from the lower portion of the SUN-003 drill hole, completed as part of the continuing phase I drill program at the Sunnyside copper-lead-zinc-silver exploration project in Arizona.

Highlights

Barksdale has intercepted multiple intervals of carbonate-replacement-style mineralization (CRD) in SUN-003, including assays released previously (see news release dated Feb. 12, 2024).

Additional assays from the lower zones of polymetallic CRD mineralization intersected in SUN-003 include the following results:

• 2.28 metres grading 1.72 per cent Zn, 0.63 per cent Pb, 13.5 grams per tonne Ag and 0.016 g/t gold from 1,480.57 m depth;
• 1.01 m grading 0.46 per cent Cu, 11.9 per cent Zn, 3.8 per cent Pb, 377 g/t Ag and 0.028 g/t Au from 1,550.67 m depth.

Barksdale aims to provide guidance for the remaining 2024 drill campaign within the next 30 to 45 days.

Rick Trotman, president and chief executive officer, states: "The final assays from the lower portion of SUN-003 contains multiple additional zones of narrow polymetallic CRD mineralization outboard of the higher-grade feeder structure. We look forward to drilling to the southeast of SUN-003, where our model suggests that we'll vector into areas of increased structural preparation, heat and fluid flow. Once we have multiple pierce points into that higher-grade corridor, we can begin stepping out to determine the true scale of the zone as it trends back towards the porphyry. The company is actively exploring a range of strategic opportunities for our upcoming drilling initiatives. We look forward to sharing these advancements with our valued investors in the coming 30 to 45 days."

About SUN-003

SUN-003 is a vertical hole collared two m from historic hole TCH-2 and was drilled to a total depth of approximately 1,653 m. It drifted slightly to the north-northeast and intersected the top of the Paleozoic carbonate rocks at 1,239 m depth, approximately 65 m to the north and 80 m deeper than discovery hole TCH-2. This confirms the general dip of the carbonate stratigraphy to be approximately 35 degrees to the north.

Over a dozen distinct horizons of strata-bound sulphide mineralization were intersected, which correlate with intercepts of historic hole TCH-2, located approximately 65 m to the southwest, as measured from the top of the carbonate sequence, and roughly 95 m distant at the bottom of SUN-003. TCH-2 displays intense calc-silicate alteration (that is, 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 favourable porous dirty limestones. Calc-silicate alteration was weak and included minor garnet (calcium/iron), 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 manganese/aluminum and Ca/Fe), diopside, smectite, saponite, epidote, chlorite, actinolite and irregular veinlets of pink calcite. Mineralization is stratigraphically controlled and commonly forms patchy textures.

The final carbonate unit encountered was the Epitaph formation, which contained three visually confirmed narrow zones of polymetallic base metal (Pb, Zn greater than Cu) mineralization in silty limestone. Mineralization is typically associated with weak calc-silicate alteration including the presence of smectite, saponite, diopside, green garnet, reddish hematite, rhodochrosite and potassium feldspar in patches. The hole was terminated at approximately 1,653 m depth.

Quality assurance and quality control

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. Sample assays are being performed by ALS Geochemistry, an accredited (ISO 9001) laboratory. Core samples are analyzed for total copper and gold as well as a multielement inductively coupled plasma analysis.

In addition to the ALS quality assurance program, Barksdale has an internal QA/QC program that includes certified reference standards from OREAS North America. These standards are of similar composition to mineral deposits found at Sunnyside. Several different standards are included in each batch of samples submitted to the lab. These controls are tracked to ensure the integrity of the assay data.
