CBC-22-01

View Drill Section

This drillhole targeted a magnetic high-to-low transition and a chargeability high and resistivity low. The dominant lithology was a fine-grained tuffaceous volcanic with the alteration dominated by a propylitic assemblage with pervasive chloritization and patchy epidote bands. Mineralization can be generalized as minor but ubiquitous pyritic stringers and disseminations with uncommon chalcopyrite in quartz-pyrite veins. The most promising mineralization was from approximately 106–120 m and included several loose bands and veins of coarse pyrite-magnetite-chalcopyrite associated with quartz veins and local flooded silica. (Fig. 3).

This drillhole targeted near a linear magnetic trend and into a chargeability high and resistivity high and collared south of the historic Betts workings. The dominant lithology was a fine-grained tuffaceous volcanic, interrupted by minor augite-phyric flows and locally clast-bearing volcanics. The alteration was dominated by a propylitic assemblage with pervasive chloritization and patchy epidote bands. Mineralization was not as strong as in CBC-22-01

This drillhole targeted a magnetic low and chargeability high and collared southeast of the historic Betts workings. The dominant lithologies were fine-grained tuffs and limestones, although the tuffs were clast-bearing over larger intervals and with larger clasts than in the previous two drillholes. The limestones are locally strongly altered over up to 19 meters to skarn assemblages variably including epidote-magnetite-garnet-chlorite-hematite-carbonate-quartz with pyrite and trace chalcopyrite.

CBC-22-04

View Drill Section

This drillhole targeted magnetic and resistivity lows and a chargeability high, and a Au soil anomaly. The tuffaceous rocks here are relatively texturally variable and overall relatively clastic and fragmental, including multiple intervals of plagioclase-phyric crystal tuffs which are ruled out as an intrusive unit based on their unaltered contacts and occasional interbedding with other volcanic units. The pervasive background chloritization and patchy epidote is locally bleached near intrusive contacts and shears, as well as the common quartz-carbonate-clay brecciation fills and flooding. These quartz-carbonate-clay zones can exceed 20 m in length and are accompanied by pyrrhotite-pyrite disseminations and breccia fills with trace chalcopyrite, locally exceeding 10–20% pyrite.

CBC-22-05

View Drill Section

This drillhole targeted a NNW-trending magnetic anomaly and a mapped NE-trending monzonitic dike, as well as trending towards the historic Iron Chief workings. Lithologies are mostly variable crystal-rich and fragmental tuffs with minor limestone. Propylitic alteration includes pervasive chloritization and patchy epidote within volcanics, and weak to moderate chlorite-epidote within intrusives; near intrusive contacts or shears, moderate to strong bleaching can occur. Aside from a 9 m interval at top of hole containing similar sulfidic quartz-carbonate-clay breccias to those in CBC-22-04, mineralization is overall similar to CBC-22-01 and -02.

CBC-22-06

View Drill Section

This drillhole targeted the same magnetic and resistivity lows and a chargeability high as CBC-22-04, but from the CBC-22-05 pad to the southeast of CBC-22-04. The dominant lithology was again tuffaceous volcanics and subordinate limestone. Other lithologies include 39 m of relatively augite-rich magnetic diorite (seemingly distinct from the magnetite diorite of earlier holes), and a fine-grained crystal tuff or volcanic sandstone with fine depositional bedding preserved (26 m). Lithological complexity in the mixed volcanics generally increased down-hole. Propylitic alteration is dominantly chlorite and epidote with local bleaching near some shears and brecciation, and the diorite contains broad patches of weak to moderate bleaching and sericitization. The best mineralization resembled the breccia-related pyrrhotite-pyrite from CBC-22-04, although here is relatively pyrite-rich with less pyrrhotite and chalcopyrite.
