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) mineralization 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 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. 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 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 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 for 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.”

QAQC/ Analytical Procedures
Rock samples from the Newmont Lake Project were sent to MSALABS’ preparation facility in Terrace, B.C., where samples were pulverized to 85% passing 75 microns. Prepped samples were sent to MSALABS’ analytical facility in Langley, B.C., where 50g pulps were analyzed for gold using method FAS-121 (fire assay-AAS finish). Gold assays greater than 100 g/t Au were automatically analyzed using FAS-425 (fire assay with a gravimetric finish). Rock samples were analyzed for 53 elements using method IMS-230, multi-element ICP-MS 4-acid digestion, ultra-trace level. Silver assay results greater than 100 g/t Ag and cobalt, copper, nickel, lead and zinc greater than 10,000ppm were automatically analyzed by ore grade method ICF-6.
Crystal Lake Mining conducts its own QA/QC program where three standard reference material pulps, two blank reference material samples are inserted for every 100 samples when analyzing rock samples.
Soil samples from the Newmont Lake Project were sent to MSALABS’ preparation facility in Terrace, B.C., where samples were prepared using method PRP-757. Soil samples were dried and screen to 80 mesh, discard plus fraction. Prepped samples were sent to MSALABS’ analytical facility in Langley, B.C., where they were analyzed for 51 elements using IMS-131 for samples with 20g or greater and IMS-130 for samples between 0.5g and 20g.
