RDP

• Overview

• About RDP

  Owned 100% by Pacific Ridge, RDP is located 40 km west of the Company’s flagship Kliyul. RDP is over 10,000 hectares in size and lies within the Stikine Terrane, which is host to numerous significant porphyry deposits in northern British Columbia, including Kemess, Red Chris, Kerr-Sulphurets and Galore Creek. 

  RDP contains several porphyry copper-gold targets (Roy, Day, Porcupine, and Bird - see Figure 1), that have been explored intermittently since the early 1970’s, including prospecting and mapping, various geochemical surveys, ground and airborne geophysical surveys, trenching and a limited amount of drilling. The Project is underlain by lower Hazelton Group volcanic and sedimentary rocks (Lower Jurassic) of andesitic and dacitic composition and the Gyr rhyolite porphyry; and by Late Triassic to Early Jurassic plutonic rocks including the Fir gabbro and Roy plutonic suite with porphyritic plugs, sills, and stocks of monzodiorite composition.

  RDP Target Areas

  

  Day Target

  Mineralization at Day includes pyrite, magnetite, chalcopyrite, minor molybdenite, and local bornite as disseminations, sheeted veins and vein stockworks in diorite and adjacent altered volcaniclastic rocks. Historical drilling includes 2,472 m in 19 drill holes. Drill highlights include 0.67% Cu and 0.93 g/t Au over 58.8 m (drill hole D-74-1) and 0.54% Cu and 0.69 g/t Au over 57 m (drill hole C-92-1)¹.

  Roy Target

  Mineralization at Roy consists of a quartz-magnetite-chalcopyrite stringer stockwork within a monzonite intrusion. Trench sampling in 1990 encountered 0.121% Cu and 0.55 g/t Au over 62 m within an 80 m trench. Shallow diamond drilling programs have been completed at Roy, but results are incomplete or unavailable except for drill hole EQ-11-01. This hole was drilled in 2011, the last time RDP was explored, and returned 0.11% Cu and 0.64 g/t Au over 122.95 m¹.

  Porcupine Target

  Discovered in 1972, the Porcupine target, was explored as a stratabound massive sulphide target. Float samples assayed as high as 17.2% Cu and 0.19% Cu with 7.98 g/t Au¹. Four holes drilled in 1972 returned sporadic results. More recent evaluation of the alteration and soil geochemistry at Porcupine suggests it is epithermal in nature and possibly related to an underlying porphyry system.

  Bird Target

  The historical Bird Target, located between Roy and Porcupine target areas, about 1.8 km west-southwest of Roy, was reassessed with mapping and prospecting. A nearby mineral occurrence with several percent chalcopyrite, quartz-chalcopyrite vein stockwork and potassic alteration (K-feldspar, magnetite), was identified in a topographic low where porphyry dykes intrude prospective (subaqueous type) volcaniclastic host rocks.

  2022 RDP Drill Program

  Pacific completed 1,861 m of drilling at RDP in six drill holes in 2022.

  Highlights

  • Starting near surface, hole RDP-22-005 returned 497.2 m of 0.37% copper, 0.40 g/t gold, and 1.6 g/t silver, including 107.2 m of 0.63% copper, 1.10 g/t gold, and 2.91 g/t silver².
  • The longest, highest-grade interval ever returned from RDP.
  • Drilling intersected zoned sulfide mineralization including a central bornite-chalcopyrite mineralized interval over approximately 260 m, from 75 m to 335 m.

  2023 RDP Drill Program

  Completed 1,428 m of diamond drilling in three drill holes at RDP.

  • 987 m in two broad step-out holes (over 300 m each) from drill hole RDP-22-005, which returned 107.2 m of 0.63% copper, 1.10 g/t gold, and 2.91 g/t silver within 497.2 m of 0.37% copper, 0.40 g/t gold, and 1.6 g/t silver at the Day Target in 2022 (see news release dated October 25, 2022) (see Figure 4).
  • 441 m in one drill hole completed at the Bird target where the Company discovered porphyry copper-gold mineralization in an outcrop exposed in a stream cutbank in 2022.
