Jul 18, 2016 (Andrew Tims) - The style of gold mineralization in the 433 Zone is comparable to that observed in the ODM/17 Zone, although some differences are apparent. These include an overall dominance of chlorite alteration (relative to dominant sericite in the ODM/17 Zone) of quartz-phyric host rocks, occurrences of chlorite-pyrite altered heterolithic conglomerates, and the occurrence of chalcopyrite and chlorite with high-grade quartz-pyrite-gold veinlets. Several subsidiary zones of gold mineralization are the HS and New Zones. The HS and New Zones are located north of and structurally beneath the ODM/17 Zone and slightly above the 433 Zone.
Nov 25, 2019 (Therese Pettigrew) - In RC 433, 808 grains of visible gold were found. The samples returned assays of up to 14.22 g/t Au (Assessment report 52C13SW0007). The 433, HS and New Zones form three of several anomalous gold occurrences in the footwall of the ODM/17 Zone, hosted by a combination of massive and fragmental felsic to intermediate rocks. The overall 433 Zone was also subdivided into three grade sub-domains based on the following divisions: 1) Greater than 0.9 gpt gold; 2) Between 0.5 and 0.9 gpt gold; and 3) Below 0.5 gpt gold. The 433 Zone therefore comprises of three geostatistically distinct geo-domains (Cole et al., 2011).
