Ann: Significant Copper in Second Hole into A4 Dome, page-15

Really liked that news release today.

The reference to "stockwork" veining I thought was very intriguing. In the corresponding Metal tiger release, their CEO highlighted it, and made reference to it being “a style previously unseen by the JV drilling.”

If you go with a generic definition for "stockwork" such as that of AGI Glossary of Geology (Jackson and Bates, 1968) a "stockwork is a mineral deposit consisting of a three-dimensional network of planar to irregular veinlets, closely enough spaced that the whole mass can be mined." - then on a general level that sounds like a general description of the T3 deposit. But they’ve previously characterised the T3 deposit as “sheeted-veins” or “stacked veins” associated with the thrust-fault, on the northern side of the dome. So Metal Tiger highlighting that it is different style is significant imo: perhaps we’re seeing a new type of deposit here – the sheeted vein deposits on the northern sides of the domes a la T3, and this new type of stockwork deposit on the southern sides of the domes?

I’ve seen the term “stockwork” used a lot to describe the veining/mineralisation in copper porphyry systems where the fractures form above an intrusion, but I think the principle is the same here, where the sediments have presumably been extensively fractured due to the stresses involved in folding and then the hydrothermal fluids have filled the fractures creating the mineralisation. Given the stresses would have been regional in scale, it could point to an extensive strike-length. Have to wait and see whether that is the case. The fact they’re referring to “stockwork” to me suggests to me that it’s a pretty dense network of veins, which bodes well for grade, and the fact they’re drilling to the north and south of it (whereas they haven’t with the first hole in A4) suggests they like the look of it.
