The next phase of our Exploration program will be heavily focused on the McFaulds Cu-Zn VMS property.
Based on results of the winter re-logging program, and the recently acquired high-resolution Heli-GT survey over this property, areas for follow-up work have been defined. Plans include step-out drilling of the McFaulds No. 3 deposit as well as ground geophysical surveying along trend and in the footwall to the McFaulds No.1 deposit where no surface time-domain electro-magnetic (TDEM) surveys have been deployed in past programs.
Drilling at McFaulds No. 3, with a current 43-101 compliant Indicated resource of 0.8Mt at 3.75% Cu and 1.1% Zn1, will test the down-plunge continuity of high-grade copper mineralization where past drilling defined a mineralized zone 10-15m in true thickness with copper values averaging 4% (Figure 1). The target zone is at or below 250m depth, which is beyond the detection limits of most airborne EM systems. Ground TDEM surveys will test along strike of the McFaulds No.1 deposit which remains open down plunge and where untested coincident gravity-magnetic-airborne EM anomalies from past surveys exist (Figure 2). In addition, the recent Heli-GT survey identified a strong discrete magnetic anomaly 2km east of McFaulds No. 1 which is underlain by a broad magnetic low interpreted to represent footwall alteration (figure 2). Taken together, this area is may represent a new, untested VMS hydrothermal center.
Noront’s Ni-Cu-PGE program for the remainder of the year will focus on new targets generated over the course of the last 6 months.
At the Sanderson property, recently acquired from MacDonald Mines, exploration will focus on a large magnetic anomaly interpreted to be an ultramafic intrusion of similar scale to the intrusive complex hosting the Black Thor Chromite deposit. In Area 7, northwest of Eagle’s Nest, exploration will continue to expand on our growing knowledge of a newly defined magmatic corridor believed to be similar in strike length to the main ultramafic sill complex hosting the Ni-Cu-PGE and chromite deposits of the Ring of Fire. Both areas represent exciting new target regions of significant scale for the Company.
Pinay Target (Sanderson Property)
Results from the Heli-GT survey recently completed over the Sanderson footwall target have outlined an elongate magnetic anomaly 4.5 kilometres in length and up to 800 metres wide (Figure 3), called the ‘Pinay’ target (Ojicree for ‘Partridge’, from the shape of the magnetic anomaly). The Pinay target is of similar scale to the intrusive complex hosting the Black Thor Chromite deposit and is interpreted to represent one of the largest undrilled ultramafic bodies in the ROF with great potential to host Ni-Cu-PGE mineralization.
Initial work on Pinay this summer will entail geochemical sampling across the main body and two sinuous extremities interpreted to represent possible feeders to the target. A follow-up winter-based rotary-air-blast (RAB) drilling program will aim to confirm the ultramafic source and test any anomalies detected in the ground geochemical survey.
Area 7 Magmatic Corridor
Rotary air blast (RAB) drilling this past winter in Area 7 confirmed the presence of several discrete mafic-ultramafic bodies within a linear structure over 19 km in length (Figure 4) believed to represent a paleo magmatic corridor which fed the overlying ultramafic sill complex hosting the Eagle’s Nest Ni-Cu-PGE deposit and chromite deposits of the ROF. Further work this summer will entail reconnaissance mapping and sampling in areas where the OGS has mapped mafic-ultramafic outcrops in the northern reaches of the Area 7 Magmatic corridor.
Gold Targeting Program
Noront will be advancing its gold efforts this summer through a large-scale compilation program and structural interpretation of highest priority areas for gold exploration in the ROF. Expected outcomes include an improved understanding of regional host structures and identification of gold hot-spots warranting further investigation. The Ring of Fire possesses many key ingredients for significant Archean lode-gold mineralization, including the presence of multiple crustal-scale faults and an abundance of reactive iron-rich host rocks. Noront’s Triple-J gold zone is an example of this, situated at the intersection of a major dextral shear zone and reactive ultramafic host rocks (Figure 5).
