Dr.
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.
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
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.

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.
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
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
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.
