The McClarty Lake property is favourably situated within the Flin Flon - Snow Lake greenstone belt, one of the largest Proterozoic volcanic-hosted massive sulphide (VMS) districts in the world. Twenty-seven copper-zinc-(gold) deposits within the belt have produced more than 183 million tonnes of sulphide ore.
At McClarty Lake, an extensive alteration system that locally hosts
massive sulphide mineralization has been traced laterally for ~2 km
(open). The degree of alteration and locally high-grade nature of the
mineralization underlines the potential for the mineralizing system to
host a precious metal rich VMS deposit(s). The sulphide mineralization
and associated alteration system at McClarty Lake is very similar to
that associated with the Chisel Lake and Lalor Lake volcanogenic massive
sulphide deposits of the Snow Lake area.
In 2015, Hudbay Minerals Inc. (“HudBay”) completed a compilation and review of all the
technical data for the joint venture claims. This work resulted in the
identification of new targets and the subsequent staking of three new
mineral claims which adjoin both the joint venture claims and claims
owned 100% by Troymet. Two of the new targets occur near the boundary
between joint venture claims and 100% owned Troymet claims. Hudbay is
planning ground geophysical surveys over the newly identified
Under the terms of the Joint Venture
Agreement, Hudbay must contribute $1,151,052 in joint venture expenditures
before Troymet is required to fund its participating interest.
HudBay-Troymet Joint Venture Claims
Early exploration on the property was hampered by a lack of outcrop
exposure and an overlying Paleozoic-aged sediment cover. In 1996, HudBay flew an airborne EM survey over the area,
outlining a conductor that was subsequently tested with two drill holes
in 1997 by HudBay and two holes in 2000 by Troymet's predecessor company.
All four holes intersected a gold and silver bearing semi-massive
pyrite horizon in altered felsic volcanics, tracing the horizon over a
50 m strike length
A deep penetrating Time Domain EM survey undertaken in 2002
subsequently defined a potential massive sulphide horizon(s) over a strike length of ~600 m.
Five holes drilled by Troymet in 2007 extended the known strike length of the
sulphide horizon to over 425 m. Significant zinc sulphide mineralization
was intersected in two holes (MC07-04 & -06) collared 225 m south
of the 1997/2000 drilling
Along with the presence of copper sulphide, this marked the first
discovery of significant base metal mineralization (the “Discovery”
zone) on the property (September 26, 2007 news release).
In 2008, Troymet contracted a helicopter-borne VTEM survey over the
entire property and drilled 8 holes
(Table 1). This drilling campaign identified
the presence of two laterally continuous massive sulphide zones: an
upper pyritic horizon intersected in 1997 and 2000 drilling, and a lower
base metal bearing horizon discovered in 2007. The lower zone was
confirmed over a strike length of 75 m and to a vertical depth of 175 m (May 15, 2008 news release).
HudBay completed a surface pulse EM survey over the
Discovery zone in 2011 and drilled three holes
(Table 1). Hole MCC001 intersected
the lower mineralized zone approximately 150 m below the intersection in
hole MC08-10 at a vertical depth of ~300 m (January 12, 2012 news release).
In 2013, Hudbay drilled a single hole to test for the down dip and
southward strike continuation of the Discovery zone. The hole was shut
down prematurely at 437 m depth due to concerns of unsafe ice
conditions. Two pyritic horizons were intersected but no significant
precious or base metal values were reported (April 12, 2013
Troymet (100%) Claims
Troymet's 2008 airborne VTEM survey identified an EM
conductor on the MAC 2 & 3 claims, situated ~1 km northeast and on trend of the Discovery
zone. In 2010, a follow-up PEM survey confirmed the anomaly as a strong bedrock
conductor. Troymet tested the Mac conductor over a 300 m strike length with three holes in 2011. All three
holes intersected altered volcanic xenoliths in intrusive rocks, some
containing strongly sulphidized zones with anomalous copper and zinc
values reminiscent of the volcanic horizon that hosts the Discovery zone
(April 11, 2011 news release).
The dominance of xenoliths and sulphidized zones within the various
intrusive bodies suggests that the volcanic horizon, where intersected,
has been partially digested. There is potential for uninterrupted
extensions of the mineralized volcanics along strike and to depth.
Further PEM surveys and diamond drilling are required to adequately
explore the Mac mineralized zone.
The massive sulphide horizons at McClarty Lake are hosted by a
sequence of variably silicified, sericititized and chloritized felsic
volcanics and volcaniclastics. The volcanic sequence exhibits a
distinctive coarse-grained porphyroblastic metamorphic mineral
assemblage that is recognized in all of the VMS deposits in the Snow
Lake area, and reflects an earlier hydrothermal event that has been
overprinted by amphibolite-grade regional metamorphism. The alteration
assemblage is considered a highly important exploration vector to
massive sulphide mineralization.
