Crystal Lake Revises Interpretation of Geochemical Data to

Review Drill Target Selection to Intercept Massive Nickel-

Copper-Cobalt Targets at Depth

Vancouver, BC – Crystal Lake Mining Corporation (TSX-V: “CLM”), or the “Company” is pleased to

announce exploration results from its EL1 Property in NW Ontario EL1 ( formerly known as the

Allen Property).

The difficulty of finding a massive sulphide source of high -grade nickel-copper-cobalt sulphides

on a large mafic-ultramafic body prompted management to employ an interpretative geochemical

study referred to as “SGH” (Spatiotemporal Geochemical Hydrocarbons”). This method was

selected in order to unravel surface mineralized trends to depth and pinpoint targets for drilling.

Following a recent re -interpretation of data with Actlabs geoscientists and Crystal Lake

consultants, the Company is confident that it has identified possible deep targets of more massive

nickel-copper-cobalt mineralization on its EL1 property though this innovative nano-geochemical

process.

SGH is an “organic”, deep-penetrating geochemical survey which targets individual metals. In this

instance, Ni, Cu and PGEs were analyzed and presented as separate anomalies. SGH is the only

known organic geochemical method that, in spite of the name, uses “non-gaseous” semi-volatile

organic compounds interpreted using a forensic signature approach. The analysis involves the

testing for 162 hydrocarbon compounds in the C5 -C17 carbon series. These hydrocarbons have

been shown to be residues from the decomposition of bacteria and microbes that feed on the

target commodity as they require inorganic elements to catalyze the reactions necessary to

develop hydrocarbons and grow cells in their life cycle. Specific classes of hydrocarbons have been

successful in delineating mineral targets found at over 950 meters in depth. SGH is unique and

should not be confused with other hydrocarbon tests or traditional analyses that measure C1

(methane) to C5 (pentane) or other gases.

Actlabs SGH analysis has successfully shown the presence of deeply buried mineral deposits for

other companies. In a Canadian Mineral Research Organization project (CAMIRO) initiated in1997,

nine of ten mineral deposits were successfully detected at study sites that were specifically

chosen where other geochemical methods were previously unsuccessful.

The study sites included magmatic Ni -Cu sulphides as one target and a unique finger print was

developed for this deposit type. The applicability of SGH for exploration has resulted in the

availability of a cost-effective method which can be used in tandem with geophysics to improve

success rate. Hence management may conduct further geophysics to improve future drilling

success.

The re- interpretation of the SGH Pathfinder Class maps illustrates anomalies that are vertical

projections over mineralization at the shallowest location. Identified nested -segmented halo

anomalies suggest that due to the significant larger dispersion patterns the source of the

mineralized fluids may be found deeper.

The SGH results at the EL1 Property survey illustrate separate an omalies with signatures

associated with copper, nickel and PGE. Based on the Laboratory SGH rating scale of 0 to 6 the

results of the Dobie intrusion study on the patented E L1 ground has been rated from 5.0 to 5.5 ;

this indicates highly rated drill targets.

Wally Boguski CEO & President of Crystal Lake states : "We are encouraged that the re -

interpretation has pointed us to increasingly prospective drill targets . The data is consistent with

our Geological team ’s belief that a possible source of massive high -grade Nickel/Cobalt

mineralization may be found at depth with further drilling”.
