Geologic structures

Type of structure Regional
Structure description In British Columbia To The North, The Quesnel Trough Partly Controls The Distribution Of Major Porphyry Copper-Molybdenum Deposits. The Starr Molybdenum Property Lies On The Projection Of This Structural Trough.

Ore body information

  • General form ATTENUATED ELLIPSE
    Length 130M
    Width 40M

Controls for ore emplacement

  • Mostly disseminated but some fracture coatings

Comments on the geologic information

  • THE NORTHWEST-TRENDING AENEAS CREEK PLUTON IS 1 MILE WIDE AND 3 MILES LONG. IT CONSISTS OF A CENTRAL PHASE AND A BORDER PHASE THAT IS IN CONTACT WITH PERMIAN ANARCHIST GROUP METASEDIMENTARY ROCKS. THE DEPOSIT IS IN THE CENTRAL PHASE OF THE PLUTON. THE PLUTON CONSISTS OF MEDIUM CRYSTALLINE BIOTITE-HORNBLENDE QUARTZ MONZONITE AND GRANODIORITE. THE PLUTON HAS YIELDED K-AR BIOTITE AGES OF 92.7 +- 6.6 M.Y. AND 98.3 +- 3.5 M.Y. A CONCORDANT K-AR HORNBLENDE AGE WAS 92.3 +- 4.3 M.Y.
