Sun Summit Minerals Delineates 12-Kilometer Porphyry Copper-Molybdenum Exploration Corridor

en.Wedoany.com Reported - On November 12, Canadian company Sun Summit Minerals announced the 2026 summer exploration results for its Buck project in central British Columbia. Through the addition of new direct-current induced polarization (DCIP) surveys and the integration of historical geophysical and geochemical data, the company identified a north-south-trending porphyry copper-molybdenum exploration corridor approximately 12 kilometers long and expanded the high-chargeability anomaly at the CR South target. Integrated interpretation results show that the corridor hosts multiple overlapping zones of magnetic anomalies, chargeability anomalies, and copper-in-soil anomalies, with only two targets having been tested by historical drilling to date.

This round of work focused on the CR porphyry trend in the western part of the project, completing 8.8 line-kilometers of DCIP surveying along four north-south-oriented survey lines spaced 400 meters apart. A total of 430 soil samples, 26 rock samples, and 13 stream sediment samples were collected, and integrated interpretation was carried out in conjunction with more than 61 line-kilometers of historical IP data accumulated between 1994 and 2019. The new survey primarily targeted the CR South target, focusing on investigating the extension of sulfide mineralization east of the previously identified high-chargeability anomaly.

The CR South target currently has an identified anomaly zone with chargeability exceeding 20 mV/V, covering approximately 1.7 km × 0.7 km, spatially coincident with an elliptical magnetic anomaly and a copper-enriched zone in potassically altered rocks, with rock samples returning copper grades of up to 1.3%. Mineralization in this area occurs mainly in granodiorite, hydrothermal breccia, and quartz-feldspar porphyry, with copper-molybdenum mineralization dominated by quartz–chalcopyrite–molybdenite veins and stockworks. Historically, 15 shallow drill holes totaling 3,570 meters have been completed at this target, including hole CR05-03 in 2005, which returned 68 meters grading 0.50% copper and 0.015% molybdenum, and hole CR07-14 in 2007, which returned 168 meters grading 0.37% copper and 0.017% molybdenum. The new IP interpretation indicates that unverified mineralization potential remains to the east of and at depth below the existing drill holes.

The CR North target, located approximately 1.8 kilometers north of CR South, has an identified anomaly zone of approximately 2.7 km × 1.0 km with chargeability exceeding 20 mV/V, partially overlapping a copper-in-soil anomaly of approximately 1.2 km × 0.6 km. This area has thick overburden and limited surface exposure, with only 2 historical drill holes totaling 876.5 meters completed in 2019. One of these holes returned 4.1 meters grading 1.05% copper. The company has also identified two additional targets, CR Far North and CR Far South, at the northern and southern ends of the exploration corridor; however, soil geochemical coverage in these two areas is incomplete, and the southern target also lacks IP survey data.

The Buck project is located approximately 10 kilometers south of the town of Houston and comprises 62 mineral claims covering approximately 53,638 hectares. This exploration program expanded the previous copper-molybdenum target studies, which were focused mainly on CR South, to a longer structural corridor. The company's next steps will be to integrate the new geophysical, soil geochemical, and historical drilling data to prioritize anomaly zones and rank drill targets.
