22. MÉNARIK EAST PROJECT – OROGENIC GOLD POTENTIAL
22
 The northern half of the Menarik Complex dips towards north
 Gold is mainly located in the felsic/mafic hanging wall of the
Complex and favorably aligned into NNW-SSE structures
 Mineralization near the Complex is more polymetallic (Ni, Cu, ±Co,
Pb, Zn, Ag) and associated with carbonatized and silicified
serpentinized peridotites (listwanites), abundant arsenopyrite
 σ3 refers to extensional joints
(±faults) associated with the
formation of an anticlinal dome
 The Camp and Lake Menarik faults
were probably major conduits for
gold transportation; untested first
priority targets

KALI PROJECT – DESCRIPTION
PROJECT SUMMARY
 Located 20 km east of the Cree Nation of Eastmain and 15 km west of Azimut’s Patwon prospect (3.15 g/t Au over
102.0 m)
 194 claims (10,232ha) 100% owned by Harfang, accessible by boat and air transportation
 Located along a major NE-SW deformation corridor separating the Middle and Lower Eastmain Greenstone Belt
[MLEGB] (south) and a suite of diverse intermediate and felsic intrusions and batholiths (north)
 Mafic to felsic volcanics and volcaniclastics intruded by gabbro masses are dominant in the southern half of the
western block of claims; many similarities with gold setting at Patwon
(3.15 g/t Au over 102.0 m)
 The NE-SW corridor
merges with the E-W
limit between the La
Grande (north) and
Nemiscau-Opinaca
subprovinces; strong
metamorphic gradient;
chemical and
structural traps for
gold precipitation
 No historical
exploration work in the
western block

between the La Grande and Opinaca
subprovinces

LAKE TAPIATIC PROJECT – DESCRIPTION
25

26. GEOLOGICAL FEATURES

(polyphased deformation)
 Major shear zones dismember fold hinges and cut
across the entire volcano-sedimentary package
 Metamorphism grades from greenschist to
amphibolite facies towards the north (metamorphic
front)
ORE POTENTIAL
 Complex structural features combined with iron-rich
lithologies offer a strong potential for gold
mineralization in both structural and chemical traps
 Copper anomalies in lake sediments are found in the
southern part of the property
 Overall geological setting shares similarities with
Musselwhite and Red Lake areas
