The Nahlin River Ni-Cu occurrence is located on the west side of Nahlin River about 1.6 kilometres south of Chastot Creek, approximately 131 kilometres north of the community of Telegraph Creek, British Columbia.
The following quote is from B.C. Government site βMinfileβ- Minfile No. 104J 031, current to 2013:
βChalcocite and native copper are reported to occur in veins and stringers in upper Mississippian-Permian serpentinite of the Cache Creek Complex. Selected samples assayed better than 15 per cent copper; an adjacent band of mineralization is reported to have assayed 0.48 per cent nickel (National Mineral Inventory card).β
Comments by Giles Peatfield regarding some of the minerals reported:
Antigorite?: Morton (undated) listed antigorite as βpossibleβ.
Chrysotile: Morton (undated) listed chrysotile as βpossibleβ.
Covellite: Morton (undated) reported traces of covellilte.
Digenite: Morton (undated) reported traces of digenite, basing the identification on etch tests. I would regard this as tentative.
Diopside?: Morton (undated) reported a β. . . green mineral in a contact β limestone with ultrabasic rock.β that he thought was possibly diopside.
βGarnetβ: Morton (undated) described an unknown mineral that he thought at first appeared similar to phrenite, but later reported that it was βGarnet by X-raysβ. He gave no specific information.
Heazelwoodite: Archer (1957) noted that heazelwoodite was confirmed by an X-ray pattern interpreted by Dr. R. M. Thompson.
Magnesite: Morton (undated) described rocks that he thought looked like β. . . some form of skarn material, [which effervesces] with HCl and hence seem[s] to be partially calcium carbonate.β This is followed by a pithy comment in Dr. Thompsonβs hand-writing β βMagnesite rich.β
