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 thirty 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.
Table 1 presents the newly received germanium results from these three techniques. It also contains
the corresponding silver-lead-zinc grades from these samples.
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
upcoming drill core for germanium using this bulk technique.
Sample Preparation
The drill holes reported in this press release were drilled using HQ (63.5mm) 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, BC
.
At CF Minerals the drill core was dried prior to crushing to -10 mesh. The samples, which averaged
over 3kg, were then mixed prior to splitting off 800g. The 800g splits were pulverized to -200 mesh.
A 250g 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 pulveriser between each sample to ensure no inter-sample 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 ICP-MS
finish. The 48 element ME-MS61 technique was used to provide a geochemical signature of the
mineralization. Where lead or zinc values exceeded one percent the Pb-OG62 or Zn-OG62
techniques were used. These have upper limits of 20% lead and 30% 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 over limit 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 0.5g
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 0.2g 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 1g sample.
