Slide 6: General Geology of the Lundmark-Akow Lake Area
GENERAL GEOLOGY OF THE LUNDMARK-AKOW LAKE AREA 6 • Originally staked to cover the northward projection of the Northern Iron Formation (BIF) that hosts the bulk of the gold at Musselwhite. • Iron Formation is part of the Opapimiskan-Markop Unit, a plume- related sequence that overlies the South Rim.
Slide 7: Lundmark-Akow L. Geology
LUNDMARK-AKOW L. GEOLOGY 7 • Oreterra’s drilling has now outlined a volcano-sedimentary basin in the South Rim assemblage west of Akow VMS Lake. • Basin is at >10 km long and up to 800 m thick. • Basin is floored by a dacitic volcanic and then filled with fine-grained clastic sediments and several f
Slide 8: South Claims Geology
SOUTH CLAIMS GEOLOGY 8 • Alteration pathway was targeted using two formational pyrite horizons located on either side identified through TEM and VTEM surveys. • Pyritic horizons are very similar to pyritic members of the “Avol” felsic Py Py unit that stratigraphically underlies the BIF at Musselwhit
Slide 9: Massive Sulphide Alteration Pathway
MASSIVE SULPHIDE ALTERATION PATHWAY 9 • 100-150 m wide schist with scattered intervals of low-grade Cu-Au throughout. • Formed by intense hydrothermal alteration of the basin sediments/tuffs. (Na2O down to 0.1%, Rb/Sr increases, etc.) • Consistent over a >8 km length. • Massive sulphides typically o
Slide 10: VMS Style Alteration Pathway
VMS STYLE ALTERATION PATHWAY 10 • Most is barren or very weakly mineralized but there are local concentrations of chalcopyrite. • Chalcopyrite is folded, indicated that it predates deformation. • Local well-developed quartz flooding and hydrothermal garnet formation +/- chalcopyrite, pyrrhotite. • S
Slide 11: VMS Style Alteration Zone
VMS STYLE ALTERATION ZONE 11 • High % of staurolite in much of the alteration zone, formed by strong hydrothermal alteration of the schist and tuff protoliths, similar to the alteration pathways in the Snow Lake, Manitoba mining camp. • The Company recently sponsored an MSc project on this VMS syste

“EPITHERMAL LOOKING” CALCITE VEINS 31 WHAT DO THEY SIGNIFY? 1. Open space filling, but under what P-T-Depth conditions? 2. Same kind of veins are found in the Red Lake gold mine. Interpreted as epithermal initially but then as deep- seated, very high-pressure fluids that kept faults open at great de
Slide 32: The Big Picture – Why Such a Variety of Mineralization in the NW Claims?
THE BIG PICTURE – WHY SUCH A VARIETY OF MINERALIZATION IN THE NW CLAIMS? 32 1. Syngenetic pyrrhotite formations + Au-Cu 2. Multiple VMS horizons 3. Stockwork Cu-Au flanking FP/QFP 4.

Slide 33: The Big Picture – Why Such a Variety of Mineralization in the NW Claims?
THE BIG PICTURE – WHY SUCH A VARIETY OF MINERALIZATION IN THE NW CLAIMS? 33 • FP and QFP intrusions are generally in mag lows. • Aeromagnetic pattern suggests there could be many more. • “Quiet” aeromagnetics and abrupt cut-off of regional EM conductors suggest there is a pluton a few 100 metres to
