Cruz Drills Broad Zone of Anomalous Silver-Copper Mineralization at the Hector Cobalt-Silver Property in Cobalt

Sep 14, 2021

Cruz Battery Metals Corp. says during July 2021, the company completed a three-hole, 837 metre diamond drill campaign at the Hector Silver-Cobalt Property. The 2021 drilling targeted the prospective lower contact of Nipissing diabase sills and Archean volcanic basement rocks at depth. 

Drill holes 21HC01 (020az/-60o) and 21HC02 (070az/-60o) drilled from the same collar intersected the base of the Nipissing diabase at 248 and 231 metres downhole respectively (Figure 1). Hole 21HC01 cut a broad zone of anomalous silver-copper mineralized mafic volcanic rocks returning assays of 0.87 g/t Ag (grams-per-tonne silver) and 0.01% Cu (copper) over 32.3 metres from a depth of 279.7 metres; including a higher-grade interval of 1.06 g/t Ag over 19.5 metres from a depth of 286.5 metres yielding individual assays of up to 3.2 g/t Ag. The silver-copper zone within 21HC021 is characterized by the presence of moderate chlorite alteration and silica flooding accompanied by fine grained disseminated chalcopyrite-pyrite mineralization.

In addition to the volcanic hosted silver-copper zone, several cobalt-copper intervals occur within drill holes 21HC01 and 21HC02 that are comparable to values returned during Cruz's initial 2018 drill campaign including: 0.03% Co (cobalt) and 0.088% Cu over 1 metre at a depth of 143 metres; 0.01% Co and 0.12% Cu over 1 metre at 74 metres downhole within 21HC02; and 0.012% Co and 0.07% copper over 1 metre at 153.5 metres downhole within 21HC01.

The true width of mineralization is estimated to be 80-90% of the drilled interval.

Drill hole 21HC03 (0250az/-50o) targeting a north-northwest striking fault structure that juxtaposes Nipissing diabase and Archean basement rocks to the north, remained in diabase to an end-of-hole at a depth of 249 metres. Textural variation within Nipissing diabase, and variation in the observed mineralization and magnetic susceptibility confirm the presence of a west-dipping, multi-phase sill complex.
