CANTEX RECEIVES EXCELLENT FIRST BULK GERMANIUM RESULTS FROM MAIN AND GZ ZONES AT ITS 100% OWNED NORTH RACKLA PROJECT, YUKON

Cantex Mine Development Corp. has provided an update on its 100-per-cent-owned, 14,077-hectare North Rackla claim block in Yukon.

Bulk germanium results

Cantex's directors are pleased to now have a method that can reliably be used to determine the bulk concentration of germanium within drill core. Determining the bulk concentration of germanium within drill core has the advantage of providing an average germanium content of the sphalerite and other minerals in the sample, as well as being more cost effective and possible to complete in a more timely fashion.

Main and GZ zone results

Cantex has undertaken an evaluation of 30 samples from the Main and GZ zones in order to identify a technique suitable for bulk analysis of germanium.

These samples were selected to represent the full spectrum of grades seen on the project to best assess the techniques. Five different analytical techniques were evaluated. Of the five methods evaluated three techniques produced results with tight precision.

The results show that, as expected, there is strong correlation between germanium content and zinc grade. This correlation was expected as it is the zinc sulphide mineral (sphalerite) that contains the germanium. Analyses of sphalerite grains from 97 intercepts within the Main zone average 654 grams per tonne. Sphalerite grains from 14 intercepts within the GZ zone average 521 grams per tonne. Thus, higher-grade zinc mineralization is expected to have substantial germanium content.

It is important to note that even the higher germanium values will be further upgraded prior to being sent to a smelter. The mineralization contains other minerals beyond sphalerite and galena which will dilute the germanium content. Many of these gangue minerals would be removed from the mineralization prior to it being sent to a smelter, increasing the germanium, silver, lead and zinc content.

Summary

Cantex's directors are pleased to have a reliable, cost-effective and timely method to establish the bulk concentration of germanium within drill core. The company intends to continue analyzing its coming drill core for germanium using this bulk technique.

Sample preparation

The drill holes reported in this press release were drilled using HQ (63.5-millimetre) diamond drill bits. The core was logged, marked up for sampling and then divided into equal halves using a diamond saw on site. One-half of the core was left in the original core box. The other half was sampled and placed into sealed bags which were in turn placed into larger bags closed with security seals prior to being transported to CF Mineral Research Ltd. in Kelowna, B.C.

At CF Minerals the drill core was dried prior to crushing to minus 10 mesh. The samples, which averaged over three kilograms, were then mixed prior to splitting off 800 grams. The 800-gram splits were pulverized to minus 200 mesh. A 250-gram portion of this pulverized material was submitted for multielement analysis at ALS Chemex in North Vancouver. Quality control procedures included running a barren sand sample through both the crusher and pulverizer between each sample to ensure no intersample contamination occurred. Silica blanks were inserted along with certified reference samples. These quality control samples were each inserted approximately every 20 samples.

ALS Chemex in North Vancouver assayed the samples using a four-acid digestion with an inductively coupled plasma mass spectrometry finish. The 48-element ME-MS61 technique was used to provide a geochemical signature of the mineralization. Where lead or zinc values exceeded 1 per cent the Pb-OG62 or Zn-OG62 techniques were used. These have upper limits of 20 per cent lead and 30 per cent zinc, respectively. Samples with lead and zinc values over these limits were then analyzed by titration methods Pb-VOL70 and Zn-VOL50. Where silver samples exceeded 100 g/t the Ag-OG62 technique was used which has an upper limit of 1,500 g/t. The overlimit analyses contributed to delays in receiving final assay results.

For the germanium results presented in this release a separate split of the remaining pulverized material was sent for analysis. Three labs, all of which are ISO/IEC 17025:2017 accredited, provided the germanium results reported in this release.

At ALS Chemex in Brisbane, Australia, the Ge-MS66 technique was used. It involved a digestion using nitric and hydrofluoric acids with an orthophosphoric acid leach and an ICP-MS finish on a 0.5-gram sample.

At ALS Chemex in North Vancouver, Canada, the ME-MS89L technique was used. The samples were digested using a sodium peroxide fusion followed by an ICP-MS finish on a 0.2-gram sample.

At ActLabs in Ancaster, Canada, the Ultratrace 7 package was used. It involves a sodium peroxide fusion followed by an ICP-MS finish on a one-gram sample.
