Canada Zinc Metals Completes Large VTEM Geophysical Survey on Akie, Pie and Mt. Alcock Properties
October 1, 2012
Vancouver, British Columbia, Canada – Monday, October 1, 2012 – Canada Zinc Metals Corp. (TSX Venture Exchange: CZX) is pleased to provide an update on the regional exploration program recently completed on the Akie and Kechika Regional projects. The Akie property is the Company’s flagship exploration project and is host to the Cardiac Creek SEDEX Zn-Pb-Ag deposit. The Kechika Regional Project, represented by a series of contiguous property blocks including Pie and Mt. Alcock, extends northwest from the Akie property for approximately 140 kilometres covering the prospective Gunsteel Formation shale. The southernmost project boundary is located approximately 260 kilometers north-northwest of the town of Mackenzie, in northeastern British Columbia, Canada.
Airborne Geophysical Survey
The Company is pleased to announce that Geotech Ltd., of Aurora, Ontario, has successfully completed a large-scale, 1,526 line kilometre airborne Vertical Time Domain EM (VTEM) geophysical survey over the Akie, Pie and Mt. Alcock properties. The primary goal of the survey was to obtain lithological and structural information near surface and at depth across the three properties, as well as define a geophysical response directly from the Cardiac Creek deposit.
A detailed orientation survey with 100 metre line spacing was conducted over the known extent of the Cardiac Creek deposit. This was intended to test the VTEM technology in the field and determine whether expected information was being acquired. The preliminary results from this orientation survey demonstrated a clear response from the Gunsteel Formation shale panel that is host to the Cardiac Creek deposit. In addition, other lithological boundaries such as the hangingwall siltstone and shale and footwall siltstones of the Road River Group were clearly defined. Interestingly, an unexpected positive response was detected to the east of Silver Creek. Based on the preliminary results from the orientation survey a decision was made to proceed with the remainder of the proposed survey over the broader Akie property, and the Pie and Mt. Alcock properties.
Coverage across the remainder of the Akie property, and Pie and Mt. Alcock properties consisted of 200 metre spaced lines. A secondary focus was placed on the West Pie target area with detailed coverage consisting of 100 metre spaced lines extending from the GPS showing to the southeast and to the property boundary to the northwest.
The final results from this survey are expected in late October after which the Company will conduct a thorough and detailed interpretation. This is the first modern airborne geophysical survey undertaken on the Company’s large land holdings. Prospecting, mapping, soil geochemistry and detailed geophysical ground surveys will be considered in 2013 for any anomalies generated by the 2012 VTEM surveys. The survey results on Mt. Alcock and Pie will also help confirm drill targets. Follow-up airborne VTEM survey infill lines may be warranted in 2013 for detail over any areas identified by the 2012 exploration program as having significant potential for sulphides.
Regional Exploration Program
Results for the recently completed water geochemistry survey conducted across a number of the Company’s properties including Akie, Pie and Mt. Alcock are still pending but are expected shortly. In total, over 120 samples were collected and analyzed for sulphate and metal concentrations.
Based on the initial field observations of turbidity, several areas returned highly anomalous levels of barium sulphate. These include the northern area of Central Pie, West Pie and Mt. Alcock. An additional sample was taken downstream of the GPS showing confirming its anomalous nature. Interestingly, certain drainages underlain by rocks of the Road River Group, generally thought to be non-prospective, returned anomalous values on the Pie, Mt. Alcock and Yuen properties. These areas will need to be investigated further in order to determine a possible source. The field observations are at this point preliminary results and will be confirmed by the analytical results at a future date, upon which final interpretations will be made. Based on the final interpretation, future sampling will focus on tertiary drainages in order to pinpoint the source of the sulphate anomalies and the presence of possible SEDEX style mineralization. For QA/QC purposes, several samples from the 2011 baseline survey were duplicated to test for possible seasonal variation; and a series of duplicates and blanks were inserted roughly every ten samples in the 2012 survey.
Historical exploration work completed on the Mt Alcock property includes diamond drilling on the Main barite showing in addition to geological mapping, geophysics, and surface geochemistry work on the Main, Nod and Seep grids. Two phases of diamond drilling were completed in 1989 and 1990, with a total of 17 diamond drill holes drilled for 2,264 metres to test a prominent white barite zone. The barite zone has a surface extent up to 500 metres long by an average of 90 metres wide. Anomalous zinc values in soils range from 500 to 6888 ppm (parts per million), and are coincident with anomalous lead values that range from 100 to 16,500 ppm. Grab samples of stratiform barite hosted zinc- lead sulphides in outcrop over a 300 metre strike length returned up to 14.8 % combined zinc- lead and 0.6 ounce per ton silver. The best drill intercept recorded (from limited drilling) was 8.8 metres grading 9.3 % combined zinc- lead, and 1.2 ounces per ton silver, in drill hole 89- 3. Drill hole 89- 9 returned the widest intercept, with 10.5 metres grading 6.8 % combined zinc- lead and 0.7 ounces per ton silver.
