Cantex has 100% ownership of several projects in Canada’s mining friendly Yukon Territory.
These projects were generated from the Company’s 30,000 square kilometre regional heavy mineral sampling program over an area favourable for Carlin style mineralization following ATAC Resources Ltd discovery of the Osiris deposit in 2010. This work identified areas which contained highly anomalous gold and pathfinder elements for Carlin-style and base metal mineralization. These areas were staked in 2012 and exploration is currently focused on the North Rackla claim block.
Exploration of the North Rackla block commenced with detailed heavy mineral sampling to define portions of the drainages which hosted mineralization. These watersheds were then evaluated using composite soil-talus samples collected at 25 metre intervals along 200 metre spaced lines. Where favourable results were obtained, infill lines were completed down to a 50 metre spacing to define the mineralization source. Almost 30,000 composite soil-talus samples have been collected on the North Rackla block.
The soil-talus sampling has identified several mineralized zones within the 15km x 15km North Rackla claim block. The most advanced of these is the Massive Sulphide Zone.
The location of the North Rackla block is presented in Figure 1.
Main Zone – Silver-Lead-Zinc Germanium
The Main Zone within the Massive Sulphide Project has so far been traced for 2.3 kilometres by drilling and hosts high silver, lead and zinc values. Recent analyses have shown this mineralization is also enriched in germanium. The mineralization is hosted in Proterozoic aged rocks and has elevated manganese values similar to the Sedex style Sullivan and Mt Isa Mines.
Since the initial drill program in late 2016 Cantex has aggressively advanced the project, with over 60,000 metres in 260 holes having been drilled. Due to the long strike length the Main Zone has now been divided into three areas: the Discover Sector, the Central Sector and the Extension Sector. These are shown in the figure below.
Figure 2. Geological map of the Massive Sulphide project.
The Main Zone mineralization is steeply dipping and is situated near the contact of argillite and dolomite units. Near surface the mineralization has been oxidized, reducing its metal content. However, at depth the fresh sulphide mineralization is preserved and exceptional silver-lead-zinc values have been returned. The depth extent of the mineralization was tested in the Central Sector, where it was intersected at 700 metres depth. Cross sections through the Extension, Central and Discovery Sectors are presented in the next three figures.

In early 2023, specialized analyses for germanium were conducted on 12 sphalerite samples from four holes in the Extension Sector. These analyses demonstrated that the sphalerite is significantly enriched in germanium. The results are presented in Table 1. Germanium is a high value Critical Metal, targeted by both Canada and the United States as a focus for development. These results suggest that germanium could add substantial value to the project.

Approximately 500 metres southeast of the Main Zone an additional zone of mineralization rich in silver-lead-zinc has been identified. A cross section through the GZ Zone is presented in Figure 5.

Regional Anomalies Within North Rackla Block
Beyond the Massive Sulphide project there are numerous areas within the North Rackla claims that show potential for mineralization. Soil sampling, prospecting and rock sampling have shown potential for gold, copper and silver-lead-zinc mineralization. A map of these identified areas is presented in Figure 7.
