Copper Lake Hits High-Grade Massive Sulphides And Copper Stringer Zone at Marshall Lake
23 5월 2018 - 8:30PM
Copper Lake Resources Ltd. (TSX-V:CPL) (Frankfurt:W0I) ("Copper
Lake" or the "Company") today announced results of its winter
drilling program on the Marshall Lake copper-zinc-silver-gold
property located 250 km northeast of Thunder Bay, Ontario, and
comprised of 10,430 hectares.
HIGHLIGHTS
- Massive Sulphides – Billiton Main Zone 30 metre
Step Out
- 1.0 m @ 3.20% Cu, 8.35% Zn, 367.00 g/t Ag and
8.01 g/t Au in hole MAR-18-07
- Near Surface Copper Stringer Zone – Gazooma
Zone Step Out
- 25.30 m @ 1.07% Cu, 20.1 g/t Ag from depth of
1.05 m, including 13.85 m @ 1.54% Cu, 28.30 g/t Ag from 11.20 m to
25.05 m in hole GAZ-18-01
Terry MacDonald, CEO comments: “We are delighted
that these step-out holes demonstrate room to expand known zones.
The high silver and gold precious metals content at Billiton was
not fully recognized previously. Despite extensive prior work,
historic drilling was very shallow and mineralization remains open
in multiple directions and as yet untested at depth.
The 2018 drill program fulfills our expenditure
requirements to earn a 75% interest in the Marshall Lake
property. We are grateful to the Ontario Prospectors
Association and the Northern Ontario Heritage Fund Corporation who
helped fund this effort through their JEAP program.”
The purpose of the program was to test three
VTEM conductors and other targets derived from a comprehensive
compilation of historic data undertaken between 2014 and 2017. A
total of 14 holes for 2,868 m were completed. A table of
significant intersections, drill hole locations and statistics is
appended (see appendices A and B).
Future
Plans
The 2018 drill program identified priorities in
the area of historic work and numerous showings.
- Main Billiton – validate historic drilling and expand to
depth.
- Gazooma – potential for shallow resource definition and trace
the stringer zone ESE.
Assessment of the upper two thirds of the
Marshall felsic volcanic pile is recommended, particularly two
strong airborne (VTEM) conductors associated with altered tuffs
overlying interpreted vent facies coarse fragmental domes located
along the south shore of Marshall Lake.
Marshall Lake’s Exceptional
Geology
The Marshall Lake property is deemed favourable
to host Cu-Zn-Ag-Au VMS (Volcanogenic Massive Sulphide) deposits of
potential economic merit.
The volcanic pile consists of a moderately east
plunging and verging anticline capped by chert-magnetite iron
formation.
The discovery of Cu-Zn showings in the 1950’s
sparked an exploration rush. Extensive yet shallow work was focused
in the lower third of the felsic volcanic pile and was constrained
by a patchwork of owners and claim boundaries. The upper portions
of felsic volcanic pile remain essentially unexplored and display
favourable geology, alteration and untested conductors.
Copper Lake has spent considerable time
consolidating the entirety of the Marshall Lake felsic volcanic
centre. A detailed digital compilation and re-interpretation of
extensive previous work was conducted between 2014 and 2017. This
compilation guided this winter’s drill program focused in the area
of previous work. A comprehensive discussion of the scope and
details of historic work including historic resource estimates,
development of new targets and geological model is available in a
NI 43-101 Technical Report dated June 07, 2016 and authored by
Thomas Hart, P.Geo (see www.sedar .com or
www.copperlakeresources.com).
The 2018 drilling serves to highlight potential
of the Main Billiton zone which remains open below 150 m depth,
displays strong precious metals contents and demonstrates
reasonable continuity in 3D modelling of historic data. Hole
MAR-18-07 was a 30 m step out from historic hole GM-78-230 drilled
by Imperial Oil Ltd in 1978 (see Appendix C).
*GM-78-230 |
7.40 m @ 2.97%
Cu, 10.98% Zn, 219.70 g/t Ag |
including |
1.65 m @ 5.50%
Cu, 31.50% Zn, 320.20 g/t Ag |
Hole MAR-18-07 serves some purpose in advancing
the process of validating historic drill information in the Main
Billiton area. A 3D interpretation of historic drill data here
(Appendix C) illustrates drill coverage and the system remains open
at depth. A table of significant historical drilling highlights
demonstrating high grade silver subintervals is also appended again
cautioning the historic nature of the data that has not been
verified by a QP and therefore should not be relied upon.
This data suggests a steeply-dipping series of
conformable lenses spanning a 300 m strike length. Only six holes
have been drilled deeper than 150 m and the system appears to
remain open at depth.
The other significant finding of the 2018
drilling was the confirmation of copper stringer mineralization at
Gazooma. This showing is part of a cluster of copper showings
located approximately 3 km southwest of the Billiton Main Zone.
They appear to align along an ESE crosscutting trend and
demonstrate a copper to zinc zonation ESE or upwards in the
volcanic stratigraphy. The projection of this trend has not been
adequately explored to date.
QAQC
All drill core was logged and split at a secure
core facility in Thunder Bay and samples were prepared by ALS
Minerals Canada in Thunder Bay and assays were performed at the ALS
lab in North Vancouver, BC. Using a multi-element Mass Spectrometer
MEMS41 method with ICP-MS finish, and any gold values over 0.1 g/t
were re-assayed with Fire Assay with an ICP finish on a 30 gram
sample. Blanks and standards were inserted every 20 samples
alternating from a blank to a standard for quality control. Samples
were assayed initially with an aqua regia digestion and a ICP-MS
analysis (ICP-MS finish) and samples greater than 1.0% Cu – Zn or
10 gm Ag were re-assayed with aqua regia digestion and an AA
(atomic absorption) finish.
QP
The Marshall Lake drill program was overseen by
George Mannard, P.Geo, consultant and managed in the field by R.S.
Middleton, PEng and field geologists were Justin Johnson, MSc.,
P.Geo and Jordan Laarman, PhD, P.Geo. The contents of this news
release were read and approved by George Mannard, P.Geo, who is
acting as QP for the Company under the rules of NI 43-101.

accessible by all-season road. CPL currently has a 75% interest in
the Marshall Lake property. The Norton Lake nickel-copper-cobalt
PGM property (69.79%), located in the southern Ring of Fire area,
is approximately 100 km north of the Marshall Lake property. It has

million tonnes @ 0.67% Ni, 0.61% Cu, 0.03% Co and 0.46 g/t Pd. The
Company recently entered into a mineral property option agreement
to acquire up to 100% of four separate Ontario properties in the
Kenora and Patricia mining belt: Queen Alexandria Gold Property,
the Mine Lake Gold Property, the Grand Chibougamau Gold Property
and the Centrefire-Redhat Gold-Copper Property.
