International Zeolite Clarifies Technical Disclosure

Vancouver, British Columbia (FSCwire) - International Zeolite Corp. (the “Company”) (TSX.V: IZ) (OTCQB: IZCFF) (FSE: ZEON), announces as a result of a review by the British Columbia Securities Commission, this news release is being issued to clarify the Company’s technical disclosure. The Company has an historic resource but no current mineral resources for the Sun Group Project. The statement in the June 30, 2017, September 30, 2017 and December 31, 2017 Management Discussion and Analysis (MD&A) indicating there are current resources was a typographical error and the Company hereby retracts the statement.

The Sun Group has an historic estimate as disclosed in the Canmark International Resources Inc. Sun Group of Claims 1994 Exploration Programme Reserve Estimate and Mine Feasibility Review and Recommendation by Phoenix Engineering Ltd. dated July 17, 1994 by W.J. Beck and W.E. Hodge. The report is filed as British Columbia Ministry of Energy and Mines Assessment Report 23457. This estimate includes 3.5 million tonnes of measured resources, 4.4 million tonnes of indicated resources and 38.7 million tonnes of inferred resources.

International Zeolite Corp. believes the historic estimate was relevant at that time.  The Company continues to hold the Sun Group property and plans to eventually undertake exploration to bring the historic estimate to current resources. The Company believes the historic estimate was reliable at that time as the exploration completed to calculate the estimate was done to the standards of the day by geologists accredited to the standards of the day.

The historic estimate was based on 19 drill holes. Cation Exchange Capacity (CEC) analyses were completed over the zeolitized sections of the core at continuous 5 foot (1.52 metre) intervals.

Measured resource estimates were made utilizing the inverse distance squared modeling variogram with cut off grade and geological index parameters. In this instance, cut-off grade is quite distinct, marked by an increase in the sodium exchangeable cation establishing a minimum modeling grade of 100 Cation Exchange Capacity (CEC). The Geological Index ranged between 1 and 3, a measure of the confidence in the available geological data. The data suggested an index value of 2, resulting in an average model grade of 116 CEC.

Indicated resource estimates used the same parameters, but were determined to lie below 1150 metres elevation. They are classified as indicated as opposed to measured because while seam thickening and thinning is suggested faulting below 1150 elevation, there was insufficient evidence to confirm faulting within the formation. 

Inferred resource estimates were based on the assumption of geological continuity.  The core and the depositional environment indicate a uniform bedded formation, truncated by erosion and possible post depositional faulting. The mapped boundary of the tephra (zeolite) unit within the claim boundary was measured at 173.6 hectares at an average thickness of 15 metres. Using a specific gravity for the zeolite of 1.79 tonnes per cubic metre, yielded an inferred reserve of 38.6 million tonnes.

These resource categories are similar to the ones set out in section 1.2 of NI43-101.

Additional drill programs were completed by Canmark International Resources in in 2001 and by International Zeolite predecessor company Canadian Mining Company Inc. in 2012. The report and data from the 2001 program is not currently available. The 2012 program consisted of 10 drill holes within the historic resource area. Zeolite thicknesses and CEC values confirmed the earlier drill results in the area of the historic measured and indicated resources. Zeolite was not located to the depth of drilling in three holes drilled in the inferred area, suggesting the stratigraphy and hence the zeolite may lie deeper or conversely part of the historic inferred resource may not exist. 

In order to bring the historic estimate to current resources, a number of the historic holes will need to be twinned. Samples at regular intervals downhole will need to be taken and sent for Cation Exchange Capacity (CEC) analyses to confirm and verify the historic drilling. In addition, samples will need to be submitted to local suppliers to confirm the suitability of the zeolite for intended applications. A market analysis will also be required to confirm the existence of a market for the Sun Group zeolite.

A Qualified Person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. International Zeolite Corp. is not treating the historical estimate as current mineral resources or mineral reserves.

The Bromley Creek Technical Report, filed on February 21, 2017 does not comply with the requirements of NI 43-101 as the mineral resource estimated is based on the Company's previous NI 43-101 Report of 2003. The 2003 mineral resources estimates contained in the Bromley Creek Technical Report dated January 31, 2017 are no longer current and therefore cannot be relied upon.

The Company will undertake to bring its technical disclosure current as expeditiously as possible. Despite the fact the MD&A statement indicating the Sun Group has current resources was clearly issued in error, the statement has nonetheless triggered the need for a current technical report. This Technical Report on the Sun Group has been commissioned with an anticipated completion date of May 31, 2018. The Company will contact a mineral resource specialist to evaluate various scenarios to bring the Bromley Creek resources current.
