The phlogopite mica of Canada occurs in pyroxenite dikes.
Chromite is a common minor constituent of basic igneous rocks of the peridotite and pyroxenite type.
The main mineralized body dominantly consists of oxide-bearing pyroxenite and peridotite, and massive and semi-massive iron and titanium oxide.
TTC-031 was drilled towards the NW at a dip of -45 degrees, and intersected multiple pyroxenite and peridotite dykes containing weak mineralization.
The hole intersected pyroxenite at 178m and encountered intermittent local oxide mineralization throughout and to the base of the hole.
The Jurassic age Cu-Ag-Pt-Pd mineralization at the Sappho area is associated with semi-massive to massive sulphide veins, blebs, pods and disseminations consisting of chalcopyrite-pyrite-magnetite hosted by pyroxenite, monzonite and syenite intrusions.
Deposit and 1.6 kms southeast of the RTM - AGE JV Property, at surface, and along the same pyroxenite and sedimentary contact which hosts the Timmins Mine Deposit.
The scandium mineralization is concentrated within the hematitic, limonitic, and saprolitic zones with values up to 350ppm Sc. In the 1980s, 134 rotary air blast (RAB) holes (for 6779 meters) and two diamond drill holes (each 250 meters deep) were drilled in the area exploring several of these Alaskan-type pyroxenite bodies for platinum group.
Hole 40 was collared furthest to the north, targeting the near surface, up-dip potential of the pyroxenite host rock.
Like Hole 40, Hole 41 was drilled to target the near-surface up-dip potential mineralisation in the pyroxenite host rock.
