Peel Mining Limited (ASX: PEX) announced that new broad and high-grade copper-mineralised intercepts were returned from the drilling at the Wirlong deposit within its South Cobar Project in Western NSW.
Significant results included 163m @ 1.08% Cu, 4g/t Ag from 233m to end of hole; 9m @ 1.78% Cu, 5g/t Ag from 294m; 91m @ 0.93% Cu, 5g/t Ag from 254m; 7m @ 5.78% Cu, 19g/t Ag from 249m; 72m @ 1.01% Cu, 6g/t Ag from 120m; and 51m @ 0.94% Cu, 3g/t Ag from 208m.
PEX said that the visual inspection and portable XRF analyses confirmed additional significant zones of chalcopyrite-dominant mineralisation in drilling completed since the last report. The company said that the processing, sampling, and assaying is continuing.
Peel Mining said that the drilling at Wirlong for a maiden mineral resource estimate is continuing.
Drilling at Wirlong
The company had commenced drilling at Wirlong is part of the Company’s “Hub & Spoke” strategy to advance each of the Company’s deposits to mineable resources, to achieve critical mass in support of a new substantial centrally located processing plant.
Drilling at Wirlong was designed to test the upper ~300m of the Wirlong Central Zone where high-grade copper (chalcopyrite) mineralisation is understood to be structurally controlled on an NW-SE orientation.
The resource definition drill program is comprised of up to ~15,000m of drilling and is anticipated to be completed in the June quarter of 2021.
The company said that multiple RC drillholes completed since re-start in mid-January had intersected significant zones of chalcopyrite-dominant mineralisation as determined by visual inspection and portable XRF analyses.
Previously reported drillholes WLRC068, WLRC069, and WLRC071 had each intersected substantial chalcopyrite-dominant sulphide mineralisation over significant downhole widths.
The company has announced that the drilling has returned new broad and high-grade copper-mineralised intercepts.
Further high-grade results
PEX said that drilling returned new broad and high-grade copper-mineralised intercepts.
Important results included WLRC073: 163m @ 1.08% Cu, 4g/t Ag from 233m to end of hole including 21m @ 2.00% Cu, 9g/t Ag from 283m; and 7m @ 2.09% Cu, 6g/t Ag from 310m; and 11m @ 1.73% Cu, 5g/t Ag from 337m; and 19m @ 1.58% Cu, 5g/t Ag from 359m; WLRC075: 9m @ 1.78% Cu, 5g/t Ag from 294m; WLRC077: 91m @ 0.93% Cu, 5g/t Ag from 254m including 11m @ 2.08% Cu, 16g/t Ag from 268m; and 6m @ 1.40% Cu, 6g/t Ag from 303m; and 7m @ 3.58% Cu, 8g/t Ag from 334m; WLRC079: 7m @ 5.78% Cu, 19g/t Ag from 249m; WLRC080: 72m @ 1.01% Cu, 6g/t Ag from 120m including 12m @ 1.70% Cu, 10g/t Ag from 137m and 13m @ 1.83% Cu, 10g/t Ag from 172m; and WLRC088: 51m @ 0.94% Cu, 3g/t Ag from 208m to end of hole including 4m @ 2.17% Cu, 8g/t Ag from 231m and 4m @ 3.35% Cu, 10g/t Ag from 255m (end of hole).
The company noted that the mineralisation is consistent with electromagnetic conductor plates and a revised structural model supporting Peel’s geophysical and geological modelling
The company said that Further drilling (as part of the current resource drilling) and geophysical surveys are planned at Wirlong.
Visual inspection of several drillholes had confirmed significant zones of chalcopyrite-dominant sulphide mineralisation including semi-massive chalcopyrite-dominant sulphides with associated significant grades of copper confirmed by portable XRF analyses. The company said that the processing, sampling, and assaying is continuing and results will be reported when available.
Peel Mining Managing Director Rob Tyson said: “The wide and high-grade copper hits reported herein, as well as those previously reported, point to the potential for a major Cobar-style copper system to take shape at Wirlong.
These results, as well as visuals and XRF analyses for drillholes still to be reported, add to an excellent start to the Company’s efforts to establish a maiden high-grade copper resource at Wirlong.
Importantly, the results lend support to our aspiration to become Cobar’s next copper-dominant base and precious metals mining Company. Once again we look forward to receiving the assays for the additional copper intercepts yielded from drilling since our last report and releasing them in due course.”
