[Goldstrike]

Ah... the question is... are you...???

This isn't about me, but to answer your question, a general definition of trenching is to strip overburden (that's gravel, rocks, and soil) from a site to expose bedrock in the search for mineralization.

could also be entrenching... digging in for the long haul... expanding living quarters... support structures... etc...

In a word, no.

Any Google search could have turned up this result:
"Trenching is usually completed at right angles to the general strike to test and sample over long lengths, as across a mineralized zone. Excavation can be either by hand, mechanical digger, or by bulldozer on sloping ground. Excavated depths of up to 4 m are common."

I prefer to have some rudimentary knowledge of the sector I am investing in.
