Mishi Lake Property
SUMMARY AND CONCLUSIONS
•
The main area of interest are the claims immediately east of the Wesdome Lease. These claims are underlain by the east-central
portion of the Mishibishu Deformation Zone which is estimated by the Ontario Geological Survey to be approximately 1.5 km in width
through the Mishi Lake Property.
•
Mishi North Gold Occurrence is located on the ESE trend of several gold prospects, including the Discovery, Hollinger, Amichi, and
Northwest. All these gold prospects are characterized by quartz veins within highly deformed and altered metavolcanic and
metasedimentary rocks near the metavolcanic-metasedimentary contact.
•
The Mishibishu Lake Stock is a high-level, late-to post tectonic intrusive body of quartz monzonite to monzonite composition which
intrudes the southern part of the Mishi Lake Property. Intrusive quartz-feldspar and feldspar porphyry dikes related to the Mishibishu
Lake Stock are common in the vicinity of several of the gold occurrences within the MDZ, including the Mishi Lake Property
•
The Discovery Prospect is located NW of the Mishi North Gold Occurrence and consists of a similar NW trending quartz vein enclosed
by an alteration envelope; grab samples by the Ontario Geological Survey ranged from 13 to 82 g/t Au.
•
Two of the soil samples from the eastern Argo claims have the highest gold response ratios from a 2012 MMI survey completed by
Kritinor Metals Inc: 164 and 28 Au Response Ratio (samples 115626 and 115632).
RECOMMENDATIONS
•
Complete a geological compilation of historical data. Locate and georeference historic exploration such as stripping, trenching, sampling,
grid lines, DDH collars.
•
Prospecting/stripping/trenching/sampling of Mishi Lake claims; grab samples should be taken at regular intervals throughout the altered
zone of the Mishi North Gold Occurrence.
•
Structural/geological mapping of the Mishi North Gold Occurrence; reconnaissance scale mapping to verify the OGS Mapping.
•
Channel sampling across the main NW trending quartz vein, including the adjacent altered wall rock. Channel samples along the strike of
the quartz vein to determine grade continuity. Channel sampling of deformed quartz veins and wallrock.
•
Geochemical orientation survey for soil sampling (i.e. partial extraction and regular analysis) across the strike extension of the NW vein at
closely spaced intervals (i.e. 5 m) and across the SE extension of the outcrop area.
•
Geochemical soil sampling program of the main shear/alteration corridor using best result from the orientation surveys (if the method is
determined to be viable as a gold indicator).
•
Establish a structural and geological model based on results of geophysics, geochemistry and geology in the area.
KNOWLEDGE GAPS
•
How much of the gold exploration potential on the Mishi Lake Property is limited because the metavolcanic-metasedimentaty contact
extends south of the shore line of Mishi Lake?
•
How significant is the presence of quartz-feldspar dikes and the monzonite stock on the location of gold occurrences? Has the late period
of quartz vein development affected the Mishibishu Lake Stock or related dikes and sills?
•
Is the paucity of drill holes and trenching east of the Wesdome Lease due to a lack of mineral exploration or is there some geological
reason?
•
Does the lack of major, continuous vein systems limit the economic viability of the MDZ to low grade, high tonnage deposits (i.e. Mishi
Deposit)?
•
Are there any felsic or mafic intrusions within the tectono-stratigraphic package that may provide a ductility contrast which could have
resulted in brittle fracture and provided a plumbing system for gold-bearing hydrothermal fluids?
