Likewise, silver and zinc anomalies point to a large, long-lived hydrothermal system. Zinc (along with lead and silver) often travels farther out from the heat source and can precipitate in cooler, outer parts of the system (for instance, in carbonate rocks as sulfides like sphalerite and galena). The fact that JUD001 intersected nearly 2% Zn in the upper 100 m (in presumably unmetamorphosed cover rocks)

suggests that mineralising fluids moved upward and outward quite a distance from the source, scattering base metals. This could be akin to an “exhaust plume” of the IRGS – much like how the giant Fort Knox IRGS in Alaska has broad low-grade halos, or how large porphyry systems have far-flung halos of zinc/lead. Silver often accompanies those base metals (e.g., as silver-bearing galena or sulfosalts), so hitting almost 2 g/t Ag at 174 m depth in JUD001

is another sign of a big fluid system. In essence, finding Ag and Zn along with Au tells us the Juno system had the capacity to mobilize multiple metals and deposit them in surrounding rocks – a positive indication of a robust, chemically rich hydrothermal system rather than a trivial, gold-only occurrence.
From an exploration perspective, these associated metals can be used as pathfinders. For example, a high zinc reading might indicate you are in the cooler outer shell, prompting you to drill deeper or further towards the intrusive center where gold might concentrate. The Juno team will be looking at ratios like Au:Cu, or Zn:Au, etc., in the core samples. In IRGS deposits, often bismuth or tellurium can be critical pathfinder elements too (though not mentioned in the press release, they likely have that data from the 49-element assays). If those elements show up, it further strengthens the IRGS affinity.
