Crystal Lake Mining Announces New Discovery of Expansive,
Multi-Element Hydrothermal Mineralized System at Newmont
Lake, BC
October 10, 2019, Vancouver, British Columbia - Crystal Lake Mining Corporation (TSXV:
CLM OTC: SIOCF FSE: SOG-FF) (“Crystal Lake” or the “Company”) is pleased to announce
the discovery of a entirely new multi-element hydrothermal system in the Chachi Corridor
(“Chachi”) containing high grade gold (Au), silver (Ag), copper (Cu), nickel (Ni), cobalt (Co), zinc
(Zn) and lead (Pb) miner alization spread over a massive area 8km long x 4km wide east of the
Newmont Lake Gold Corridor, along the Eskay Rift, in the heart of the Golden Triangle.
At least three different styles of mineralization over the expansive area have returned assays from
multiple samples, in different occurrences from surface outcrop (in-situ grab and chip samples)
ranging up to 21.03 g/t Au (gold), 2,350 g/t Ag (silver), 5.4% Cu (copper), 7.7% Ni (nickel), 0.85%
Co (cobalt), 15.2% Zn (zinc) and 6.2% Pb (lead). The mineralized system runs along the eastern
side of the McLymont Fault and is coincident with a continuous >2km long geophysical anomaly.
Maurizio Napoli, President / CEO of Crystal Lake commented “At the start of the 2019 program on
CLM’ s Newmont Lake Project, the Chachi Corridor was the most underexplored area within the
large land package. We carried out an extensive large maiden exploration program and what’ s really
exciting is that the 2019 surface exploration program has identified a new, large mineral system
coincident with a 2019 >2km chargeability IP anomaly and an aeromagnetic anomaly centered on
a major fault system which is associated with high grade gold mineralization in the Newmont Lake
area to the southwest. Moreover, the discovery of high-grade nickel, copper, cobalt, zinc and lead
was unexpected and remarkable. The 2019 program of work supports exploration for high grade
Au-Cu mineralization along the Chachi corridor . The presence of high-grade VMS style and Ni-Co-
Cu arsenide mineral occurrences highlights the potential for the discovery of base metal deposits
along this richly endowed metal corridor.”
Discussion of 2019 Chachi Corridor Program
Multi-element soil geochemical data and rock samples from newly discovered occurrences point
to a multi -element geochemical anomaly spread over an 8 km by 4 km footprint spatially
associated with the fertile McLymont Fault structure including high-grade Au-Ag-Cu sulphide
(gold, silver, copper sulfide), high-grade Ag-Zn-Cu-Pb (silver, zinc, copper, lead), and high-grade
Ni-Co-Cu-Ag arsenide /sulphide (nickel, cobalt, copper, silver arsenide associated with
stockwork copper sulfide mineralization).
A recently completed Induced Polarization (“IP”) ground geophysics survey in 2019 has detected
a chargeable conductive anomaly within the soil chemical anomalies and occurrences in the
footwall of the Mclymont Fault. Over 2000 soil samples, 2000 hyperspectral measurements, and
800 rock samples were collected from this area.
The results highlight a newly discovered Au-Ag-Cu occurrence, named the Leo Zone, associated
with quartz veins within the footprint of a 600m long IP anomaly. Multiple samples yielded grades
of 5.82-21.03g/t Au along with high-grade Ag and Cu (See assays listed below).
Exploration of the Cuba showings identified high-grade Ag-Zn-Cu-Pb sulphide mineralization
associated with barite along the 3.2 km long Cuba -Thumper trend to the east of the Mclymont
Fault corridor. Grades of 5-2,350g/t Ag , 15.2% Zn and up to 5.4% Cu provided reason to
undertake follow-up chip-channel sampling which reproduced high concentrations of Ag, Zn, Cu,
and Pb over 1.5-4.8 m wide intervals (See assays listed below).
The hydrothermal Au -Ag-Cu and Ag -Zn-Cu-Pb falls within the footprint of newly discovered
high-grade Ni-Co-Cu-Au-Ag arsenide/sulphide mineralization at the brand new Brass Rose and
Grey Rose occurrences containing vein-hosted and semi-massive niccolite-gersdorffite-cobaltite
with grades up to 7.7% Ni (See assays listed below). Importantly, gabbroic intrusions found within
the area of these occurrences are commonly associated with magmatic sulphide deposits.
These findings will underpin an aggressive exploration effort in the Chachi area that expands
coverage of IP, utilizes Electro-Magnetic (“ EM”) geophysics survey to locate conductive
mineralization, with plans to define best targets for drilling.
Cole Evans, President / CEO of HEG commented; “The Chachi Corridor is still in its infancy of
exploration, but the large 2019 program of work has identified important new mineral occurrences
as well as geochemical and geophysical signatures indicative of a major mineralizing event. HEG
as a services company has been fortunate to work on many good properties across the Golden
Triangle in British Columbia, but Chachi is different from anything we have ever seen before. My
hat is off to our entire technical team fo r pulling this discovery together and letting the numbers
speak for themselves. This is an 8km x 4km area that had previously never received any ground
geophysics, intensive prospecting, detailed mapping, hyperspectral sampling or drilling; I do not
think many people would have imagined how successful the Chachi grassroots campaign would have
been for Crystal Lake this season.”
