ISSUE-282 Initial trial editing matrFacility with specific mining concepts

[skybristol]

In response to the issue I posted for this, I'm throwing this in as a trial balloon. I want to see what is involved in contributing to SWEET via the process set up currently. For this area, I have a couple dozen additional mining facility type concepts pulled from the 1997 AGI resource indicated in prov:wasDerivedFrom.

I would specifically welcome comments on the following:

• Is this the correct way to cite a source like this that has not been published in formal ontology form (at least not in a usable/citable way)?
• What's the gold standard we are shooting for in terms of additional detail in annotations? There's more I could provide here within the established namespace properties.

I should add that I believe this simple addition of three mining facility concepts can be merged as is. I'll open another issue to complete work in this area once I understand the contribution pattern.
