| Subject category | Comment text |
|---|---|
| Deposit | Model Name = Polymetallic veins |
| Deposit | Other Comments = the name Bevacque (Bervaqua) has been associated with this occurrence (Buddington, 1929).? Elliott and Koch (1981, p. 13, loc. 43) list silver and gold as queried commodities at the North Star prospect, but do not mention them in their description of the deposit. Nor is silver or gold mentioned in any of the earlier published descriptions of the prospect. |
