Pacific Ridge completed a total of 19 diamond drill holes (KLI-23-051 to KLI-23-069) totaling 10,284 metres at Kliyul this year, the largest ever exploration program at the Project. The Company announced drill results for holes KLI-23-051 to KLI-23-054 in August with drill hole KLI-23-054 returning 305.5 m of 0.59% CuEq or 0.87 g/t AuEq (0.23% copper, 0.51 g/t gold, and 1.22 g/t silver). Pacific Ridge announced drill results for holes KLI-23-055 to KLI-23-059 in October with drill hole KLI-23-058 returning 103.5 m of 0.63% CuEq or 0.93 g/t AuEq (0.18% copper, 0.66 g/t gold, and 0.93 g/t silver) within 388.5 m of 0.42% CuEq or 0.62 g/t AuEq (0.18% copper, 0.35 g/t gold and 1.05 g/t silver). Results for the remaining seven drill holes will be released once they are received and compiled.

Drill hole KLI-23-062 returned 113.0 m of 0.48% CuEq or 0.71 g/t AuEq (0.22% copper, 0.36 g/t gold, and 1.65 g/t silver) within 485.7 m of 0.27% CuEq or 0.40 g/t AuEq (0.15% copper, 0.17 g/t gold, and 0.89 g/t silver).
Drill hole KLI-23-062 is the westernmost drill hole to be completed entirely within the
Drill hole KLI-23-060 returned 61 m of 0.40% CuEq or 0.60 g/t AuEq (0.18% copper, 0.32 g/t gold, and 1.67 g/t silver) within 100.0 m of 0.35% CuEq or 0.51 g/t AuEq (0.16% copper, 0.26 g/t gold, and 1.38 g/t silver).
Drill hole KLI-23-060 was one of three holes, and the westernmost hole, drilled in an east-west fence in KMZ North. KLI-23-060 tested an undrilled area more than 100 m away from any previous drilling and extended porphyry copper-gold mineralization approximately 130 m west of KLI-23-058, which returned 103.5 m of 0.63% CuEq or 0.94 g/t AuEq (0.18% copper, 0.66 g/t gold, and 0.93 g/t silver) within 388.5 m of 0.42% CuEq or 0.62 g/t AuEq (0.18% copper, 0.35 g/t gold and 1.05 g/t silver).
Drill hole KLI-23-060 provides further evidence that KMZ mineralization extends across the Valley Fault. KLI-23-060 is 125 m north of the previous northernmost KMZ drill hole KLI-21-036, which returned 291.7 m of 0.79% CuEq or 1.18 g/t AuEq (0.28% copper, 0.74 g/t gold and 2.04 g/t silver within 437 m of 0.64% CuEq or 0.95 g/t AuEq (0.22% copper, 0.60 g/t gold and 1.62 g/t Ag).
Drilling to date has expanded the known extents of KMZ mineralization to 630 m east-west, up to 600 m north-south, and up to 600 m vertical depth. KMZ remains open in every direction.

Summary of Drill Holes KLI-23-059 to KLI-23-062
KLI-23-059 (azimuth 225-degree, inclination -58-degree, planned length 600 m, drilled length 607 m) was collared at the Parish Hill target, 1 km southeast of KMZ within a broad moderate-intensity RMI aeromagnetic anomaly that follows the Lui fault. A northwest-trending 330 x 100 m lens-shaped MVI magnetic high anomaly comes to surface here following a lithological contact between
Lithology consists of intercalated volcaniclastic andesite, quartz diorite (up to 13.0 m wide) and andesite dykes to 118.9 m. This zone is faulted, sheared and broken to about 90 m. From 118.9-172.2 m there is an augite-phyric pyroxenite unit with a faulted footwall contact. From 223.5-340 m is a zone of alternating plagioclase-phyric flows (up to 28.7 m wide) and a carbonate-volcaniclastic fragmental unit. The remainder of the drill hole is coherent andesite with feldspar porphyry dykes (up to 14 m wide) and a gabbro dyke (53.7 m wide) at 520.6 m.
Alteration is predominantly chlorite-sericite with lesser sericitic and propylitic to 50.0 m after which propylitic alteration intensifies to moderate. Alteration of the pyroxenite unit includes dolomite, illite, fuchsite; magnetite alteration starts at 128.1 m and biotite alteration increases after 143.5 m towards the pyroxenite footwall contact at 172.4 m. In the footwall zone chlorite-sericite again intensifies and magnetite is replaced by hematite; a shear zone at 181-183 m has a skarn altered appearance and Fe-carbonate. Local garnet-epidote +/- wollastonite +/- K-feldspar skarn intervals with carbonate occur from 223.5-275.8 m. Below the skarn zone, chlorite-sericite alteration predominates with lesser carbonate and patchy potassic (magnetite +/- K-feldspar) to 370.5 m, after which propylitic alteration predominates to end-of-hole.
Mineralization includes disseminated chalcopyrite associated with skarn intervals. These locally occur with D-veins (quartz-pyrite-chalcopyrite) at 252.0-253.3 m and 319.6 m and with disseminated and stringer pyrite. Trace chalcopyrite and pyrrhotite is noted after 552 m to end-of-hole.
The 11.9 m interval of 0.12% CuEq or 0.18 g/t AuEq (0.04% Cu, 0.10 g/t Au and 1.02 g/t Ag) from 181.1 m is associated with the skarn altered shear zone. It is also anomalous in tungsten (17.9 ppm). A deeper 16.7 m interval of 0.08% CuEq or 0.12 g/t AuEq (0.06% Cu, 0.02 g/t Au and 0.65 g/t Ag) from 247.1 m is a skarn zone with D-veins and is also anomalous in tungsten (68.3 ppm).
KLI-23-060 (azimuth 90-degree, inclination -85-degree, planned length 600 m, drilled length 617 m) was drilled in KMZ North and was the westernmost of three drill holes comprising an east-west fence across KMZ North. It tested an undrilled area over 100 m from any previous KMZ drilling.
Lithology is mainly volcaniclastic andesite (86%) with feldspar porphyry dykes (up to 64.1 m wide) to 492.9 m. From 492.9-544.3 m is a zone of alternating feldspar porphyry (up to 11.8 m wide) with hornblende andesite dykes (up to 26.3 m wide). From 544.3-613.0 m is volcaniclastic andesite with quartz diorite dykes (up to 9.3 m wide).
Alteration is anhydrite-bearing inner-propylitic alternating with chlorite-sericite. Weak patchy magnetite alteration starts at 122 m. At 409.8-419.2 there is a sericite cemented breccia and a shear zone from 426.5-437.2 m with intensified inner-propylitic and chlorite-sericite alteration; magnetite alteration becomes moderate strength to 509.5 m. From 509.5 m to end-of-hole local sericitic and chlorite-sericite alteration predominate.
Mineralization includes disseminated and fracture-fill pyrite. Disseminated chalcopyrite starts with magnetite alteration at 122 m. There is an apparent zonation of vein types with intermediate-stage anhydrite +/- epidote +/- chlorite +/- sulphide veins more predominant from 80.0-475.0 m, and then early-stage quartz +/- sulphide veins more predominant from 475.0 to end-of-hole. There is a zone of D-veins between 576.6-586.9 m.
The 61 m interval of 0.40% CuEq or 0.60 g/t AuEq (0.18% Cu, 0.32 g/t Au, and 1.67 g/t Ag) from 191.0-252.0 m is associated with disseminated pyrite and chalcopyrite, weak magnetite, and inner-propylitic alteration with anhydrite +/- chlorite and epidote veinlets at the lower contact and footwall zone of a feldspar porphyry dyke. Interestingly, a 30-cm-wide D-vein (quartz-pyrite-chalcopyrite) with strong sericitic alteration at 584.3 m returned 7.96% CuEq or 11.83 g/t AuEq (0.81% Cu, 10.25 g/t Au, and 35.5 g/t Ag) over a 2 m sample. Indium (0.66 ppm) and tellurium (26.8 ppm) are also anomalous with the vein.
KLI-23-061 (azimuth 055-degree, inclination -57-degree, planned length 450 m, drilled length 299 m) was collared at the Ginger South target approximately 1 km south of KLI-23-055, which tested the Ginger target, and 1.3 km west of KMZ. Ginger South lies near the intersection of the ENE-trending Valley Fault corridor with the northwest-trending
Lithology is within the sandstone-carbonate subunit of the
Alteration is chlorite-sericite with lesser sericitic and carbonate alteration. Patchy skarn alteration starts at 84 m and continues to 170.4 m. Weak albite starts at 150.3 m and is bedding controlled. Carbonate volcaniclastic rocks at 170.4 m are dolomite cemented.
Mineralization includes disseminated and vein-hosted pyrite. Pyrrhotite +/- chalcopyrite starts after 38 m associated with late-stage quartz +/- calcite veins. Disseminated pyrrhotite, chalcopyrite and sphalerite occur locally.
The 3.0 m interval of 0.18% CuEq or 0.26 g/t AuEq (0.03% Cu, 0.21 g/t Au and 0.61 g/t Ag) from 224.0-227.0 m is associated with a massive white quartz D-vein (quartz-sericite-chlorite-pyrite). Tellurium is also anomalous (5.8 ppm).
KLI-23-062 (inclination -90-degree, planned length 350 m, drilled length 563 m) is the farthest west drill hole to be collared and completed entirely within KMZ. It was drilled vertically to test a gap between KMZ and KMZ West near the intersection of the northwest trending Lui Fault and east-northeast trending Valley Fault.
Lithology is mainly volcaniclastic andesite host rock to 295.3 m. Narrow dykes (< 2.8 m wide) of feldspar porphyry and quartz feldspar porphyry occur at 150 m and 170.2 m. From 295.3-452.5 m is a swarm zone of narrow dykes (1 m to 14.7 m wide) including quartz diorite, feldspar porphyry and hornblende porphyry with intervening volcaniclastic andesite host rock. From 452 m to end-of-hole, volcaniclastic andesite again predominates with local narrow dykes (1 m to 12.2 m wide) of quartz diorite, feldspar porphyry and hornblende porphyry. A flat-lying ductile shear zone is noted at 517-521 m.
Alteration includes moderate patchy magnetite with overprinting sericit and chlorite-sericite to 142.0 m. After 142.0-170.2 m, magnetite is weak and patchy, occurring with chlorite-sericite and local sericite +/- albite +/- quartz bleaching. From 170.2-452.5 m, in the dyke swarm zone, is a mix of chlorite-sericite with inner-propylitic (epidote +/- albite) alteration and patchy magnetite. From 452.5 m to end-of-hole, sericitic alteration and bleaching again intensifies with locally weak to nil magnetite.
Mineralization includes disseminated and vein-hosted pyrite and chalcopyrite. Vein types are a mix of intermediate-stage (epidote +/- anhydrite +/- sulphide) and early-stage (quartz +/- magnetite +/- chlorite +/- sulphide). Within the mineralized dyke swarm, intermediate-stage veins predominate. Intermediate-to-late-stage pyritic D-veins occur with sericitic alteration at the shallow (hangingwall) margin of the dyke swarm and may be related to a megacrystic feldspar porphyry dyke.
The 113.0 m interval of 0.48% CuEq or 0.71 g/t AuEq (0.22% copper, 0.36 g/t gold, and 1.65 g/t silver) from 13-126 m is associated with moderately strong magnetite alteration with early-stage and intermediate-stage veins. Within this interval at 54-84 m, Zn is anomalous (1,089 ppm) and indium (0.20 ppm). The deeper interval of 0.27% CuEq or 0.40 g/t AuEq (0.16% copper, 0.15 g/t gold, and 0.73 g/t silver) from 276.0-440.3 m is associated with intermediate-stage veins and weak patchy magnetite.
