This post is so far off topic as it bears no comparison to SLI.
Trevali is an active mine.
Trevali is predominantly a zinc mine with lead, copper and some silver.
Despite a recent interest of just over 7% by Glencore, Trevali is still 32% off their high from the last 52 weeks.
Wildly speculative to even compare this action to what may happen with SLI.
