ECU is the silver SGR imo:

So we have an increasing and already impressive gold grade and they haven’t hit the favorable intrusive contact yet. The Massive Sulfides are also rich in silver and base metals. The second vein is around 1 oz per tonne of gold equivalent! This is already spectacular but it is likely to increase as the intrusive contact is encountered as inferred by ECU! What is even more exciting is that the intrusive contact body could well be in excess of 3 million tonnes (these are my estimates base on a 500m x 100m x 15m mineralized intrusive contact which is reasonable considering the size of the intrusive) . The math on those numbers is stupendous! Judging by the response of the market investors are not paying attention to this. This latest news is showing that ECU has indeed very likely hit the "MOTHERLODE" which will transform the company but it seems that investors need it to be spelled out!

Another impressive aspect of the press release was the fact that this drill hole will allow an inclusion of an inferred resource block that is 160% taller in height than what is currently included (2.6x). The current block is 70 million ozs but the new drill will also increase average grades so the inferred category could increase by more than 2.6x to over 180 million ozs of silver eq.

I saw one pathetic analyst report today that only mentioned the increase in the inferred category as the implication of this new drilling!! Hello! The lights are on but is anyone home? What about the implications of hitting the mother lode; the evident source of all the Santa Juana mineralization? It is difficult to know how some people become analysts. It seems they don’t even have basic reading skills!

The fundamentals for ECU are now getting explosive. It will take very little additional drilling for this to become OBVIOUS to even a six year old and perhaps some analysts!
Cheers
