Carmacks Copper Belt


  • 180km long by 60 km wide belt of intrusion hosted Cu-Au-Ag mineralization in the Dawson Range.
  • Centered on the Minto Mine the belt extends from north of the Yukon/Pelly River confluence southeast to the community of Carmacks.
  • Occurrences are hosted in, or close to the contacts of, intermediate to felsic intrusive and meta-intrusive rocks of the Early Jurassic Minto Suite.
  • Minto Suite members the Granite Mountain Batholith (GMB) and the Minto Pluton host the Minto, STU and Carmacks Copper occurrences.
  • On the STU property the GMB is the dominant rock type. It is cut by aplite, microganite and pegmatite dykes and contains lenses of foliated to gneissic quartz-feldspar-hornblende-biotite granodiorite which contain most of the mineralization. The foliation strikes northwest and dips from moderate to steep to the southwest or northeast.
  • Copper mineralization is contained in the foliated to gneissic granodiorite, probably formed as shear zones, similar to the Minto mine & the Carmacks Copper deposit.
