On the north-west side of Douglas Channel, opposite the north end of Hawkesbury Island, British Columbia; Skeena Mining Division.
The following quote is from B.C. Government site βMinfileβ- Minfile No. 103H 018:
βIrregular shaped pegmatite masses of feldspar and quartz occur in quartz diorite of the Coast Plutonic Complex. Erratically distributed and irregular shaped pods of chalcocite, bornite and covellite with minor chalcopyrite, gold and silver occur mainly with the feldspar near the margins of the pegmatite and locally within the country rock. A large pegmatite mass, measuring at least 100 by 30 by 15 metres, which has been explored by underground workings contains lenses of bornite and chalcocite up to 1.2 metres wide. A 4.5 tonne sample assayed 50.6 per cent copper, 606.9 grams per tonne silver and 57.3 grams per tonne gold (Minister of Mines, Annual Report 1921).
Recorded production for 1918 to 1926 totals 1,773 grams of gold, 49,018 grams of silver and 33,423 kilograms of copper.β
Comments by Giles Peatfield regarding some of the minerals reported:
Anorthoclase: This mineral was reported by Dolmage (1922). Although not recognized as a valid species in the most recent edition of Fleischerβs Glossary of Mineral Species 2018 (Back, 2018), it is widely recognized, as a K-rich albite, by numerous other authorities. If for no reason other than historical interest, it should be allowed to stand.
Covellite: Clothier (1918) reported covellite. This was not reported by Dolmage (1922), but given the association should be allowed to stand.
βGreen micaβ: Dolmage (1922) reported green mica, with no further information. However, at the Surf Inlet Mine, which is in many ways geologically similar to Drum Lummon, he reported (p. 33A) that βA bright greenish coloured mica with optical properties closely approximating those of mariposite, or chrome mica, was found in small quantities . . . .β Green micas are a mineralogical minefield, and it would be best to simply refer to βgreen micaβ in this case.
Tetrahedrite: Clothier (1918) reported tetrahedrite. This was not reported by Dolmage (1922), but given the association should be allowed to stand.
