| Basis for focus area |
Polygons extracted form Hibbard and others (2006). Serpentinite-associated deposits along the Baie Verte Brompton line (Auclair and others, 1993; Mosier and others, 2009; Stephens and others, 1984; Trottier and others, 1991). Numerous VMS deposits occur in Quebec, Canada in correlative rock units associated with the Peri-Laurentian Arc system focus area. Two well documented Ni deposits occur at the margin of this focus area in Connecticut. |
| Identified resources |
Unknown (numerous VMS deposits occur in Quebec, Canada in correlative rock units associated with the Peri-Laurentian Arc system focus area). |
| Production |
None. |
| Status |
Past mining in Quebec. |
| Estimated resources |
Unknown. |
| Geologic maps |
Horton and others (2017), scale 1:500,000; Rodgers (1985), scale 1:125,000; Gates and Christensen (1965), scale 1:24,000; Gates and Bradley (1952), scale 1:31,680. |
| Geophysical data |
Inadequate Rank 5 aeromagnetic and aeroradiometric coverage. |
| Favorable rocks and structures |
St. Daniel mélange and ultramafic rocks along the Bai Verte Brompton line in Quebec extend into far northern Maine. Correlative rocks occur along strike to the south in the United States and include the Hawley mineral belt in Massachusetts. |
| Deposits |
Quebec, Canada: Eastern Metals (also known as Panet Metals), near the Maine border (see Auclair and others, 1993; Mosier and others, 2009; Stephens and others, 1984; Trottier and others, 1991); Connecticut: Hodges nickel prospect (MRDS dep_id: 10068172), Mount Prospect (MRDS dep_id: 10067868). |
| Evidence from mineral occurrences |
MRDS; Auclair and others (1993); Mosier and others (2009); Stephens and others (1984); Trottier and others (1991). |
| Geochemical evidence |
Favorable mineralogy and rock type. |
| Geophysical evidence |
Unknown. |
| Evidence from other sources |
Unknown. |
| Comments |
Numerous VMS deposits in Quebec (Canada) are in correlative rock units that extend into the United States in this Peri-Laurentian Arc system focus area. Potential tie-in with USGS-MRP priority efforts towards cross-border collaborations with Canada as a part of the "US-Canada-Australia Critical Minerals Initiative". |
