Barksdale Intercepts 15m of 1.48% Copper and 21m of 0.61% Copper at San Javier in Sonora, Mexico
Vancouver, British Columbia--(Newsfile Corp. - April 26, 2022) - Barksdale Resources Corp. (TSXV: BRO) (OTCQX: BRKCF) ("Barksdale" or the "Company") is pleased to announce additional assay results from its Phase I, 5,000-meter drilling program at the Cerro Verde zone on the San Javier project in Sonora, Mexico. The latest results from San Javier have expanded the footprint of the Cerro Verde copper zone to the west.
- Drilling results received from holes SJ21-30, SJ21-32, SJ21-33 and SJ21-34 continue to confirm and expand the footprint of the Cerro Verde zone. Key results include 21 meters of 0.61% copper and 0.28 g/t gold from 54-75m (SJ21-30), 15 meters grading 1.48% copper from 153-168 meters (SJ21-30), 12 meters grading 0.80% copper from 75 to 87 meters (SJ21-032), and 66 meters grading 0.33% copper from 99-165 meters (SJ21-32).
- Additionally, hole SJ21-30 intercepted multiple intervals of oxide gold mineralization including 21m grading 0.47 g/t gold from 36 meters depth, 6 meters grading 1.90 g/t gold from 87 meters depth, and 9 meters grading 1.12 g/t gold from 117 - 126 meters depth.
Rick Trotman, President and CEO of Barksdale commented: "Although we faced delays due to laboratory issues, the long-awaited final results from our phase I drilling program at San Javier have not disappointed. Two additional holes on the western flank of Cerro Verde have intercepted broad zones of mineralization further to the west, while hole SJ21-32 has confirmed copper mineralization in addition to further extending oxide gold. We now look forward to completing an initial mineral resource estimate at Cerro Verde while planning the next phase of exploration. This will likely include targets at the La Trinidad and Mesa Grande prospects."
Drill Hole Discussion
Hole SJ21-30 (Figure 1) was designed to add additional confidence within the Cerro Verde zone while providing opportunities to expand the shallow gold oxide zones encountered in nearby holes. The drill hole intersected multiple intervals that successfully extended oxide gold mineralization to the south including: 21 meters grading 0.47 g/t gold, 9 meters grading 1.11 g/t gold, and 9 meters grading 1.9 g/t gold, among others. Additionally, multiple copper oxide zones were encountered including 21 meters grading 0.61% copper and 15 meters grading 1.48% copper.
Drill holes shown in Figure 2 were designed to add confidence within the known mineralized zone (SJ21-32) as well as to test the western expansion potential of Cerro Verde (SJ21-34). Infill drill hole SJ21-32 targeted copper mineralization and intercepted multiple zones of oxide copper, including: 27 meters grading 0.31% copper, 18 meters grading 0.36% copper, 12 meters grading 0.80% copper, and 63 meters of 0.33% copper. Hole SJ21-34 intercepted multiple shallow copper intercepts that successfully expanded the Cerro Verde zone to the west, including: 15 meters of 0.23% copper and 6 meters grading 0.29% copper. At a lower cut-off of 0.10% Cu (vs. 0.2% Cu), these zones form a broader, continuous zone of lower grade mineralization that extends from 3 meters to 102 meters depth, grading 0.17% copper.
Drill hole SJ21-33, shown in in Figure 3 was designed to test the western extension potential at Cerro Verde. It intercepted a broad interval of copper mineralization from surface to 96 meters that graded 0.21% copper (0.10% cut-off) and contained higher grade sub-intervals (0.20% cut-off) that included 33 meters grading 0.29% copper, 3 meters grading 0.42% copper, and 6 meters grading 0.25% copper.

Quality Assurance and Quality Control
Drilling was completed using HQ size diamond drill core and core was logged by geologic consultants engaged by the Company. Drill holes were 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 wooden core box for storage on site. Sample assays are being performed by Skyline Assayers & Laboratories, an accredited (ISO 9001) laboratory. Core samples are analyzed for total copper, acid soluble copper, cyanide soluble cooper, as well as well as a multi element ICP Analysis.
The analytical work has been and is subject to a QA/QC program that includes certified reference standards from OREAS North America. These standards are of similar composition to the rock types at San Javier. 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. Results are all within acceptable limits.
