KELOWNA, BC, Oct. 28, 2020 /CNW/ - Cantex Mine Development
Corp. (TSXV: CD) (the "Company") has released an update on the
work program at its 14,077 hectare North Rackla claim block where
drill results continue to define a lead-zinc-silver mineralized
system with Broken Hill Type (BHT) affinities.
Dr. Chuck Fipke reports
HIGHLIGHTS
- First hole testing the newly discovered GZ Zone intersects
strong massive sulphides
- Rock samples collected during prospecting define a new gold
rich zone and an extremely rich silver-copper zone
- Initial results are available for Main Zone drilling at pads
MZ34 and MZ3X including YKDD20-159 intersecting several high grade
zones significantly extending the depth of known mineralization to
550 metres below surface
- Drilling continues
GZ ZONE
Trenching was conducted in the vicinity of six near-source talus
boulders that averaged 281 g/t silver, 18.93% lead and 32.29% zinc
(see September 14, 2020 release)
located about 550 metres southeast of drill pad MZ 5 in the
exceptionally high-grade Extension Zone. The location is
shown adjacent to drill pad GZ01 in Figure 1.
President and Geologist Chad Ulansky, who has viewed all
mineralization on the property, says that this GZ Zone contains the
highest-grade surficial mineralization he has ever encountered on
the entire property. Trenching was completed to a depth of 6
metres but bedrock was not encountered over the mineralized
zone. However, massive sulphide boulders were found in the
bottom of the trench and are believed to be very close to
source. Eight additional sub-outcrop and talus sample results
are now complete and reported in Table 1. Similar to the
initial samples taken upon discovery, they contain extremely high
values of silver, lead and zinc with contents ranging up to 395 g/t
silver, 63.65% lead and 43.86% zinc.
With the trenching supporting a proximal source a drill hole was
oriented at an azimuth of 225 degrees and inclination of -45
degrees at the exceptionally mineralized sub-outcrop. This
drill hole intersected strong silver-lead-zinc massive sulphides
and vein mineralization between 73.15 and 80.9 metres.

This intersected mineralization is similar in style to the
highest-grade mineralization intersected from pad MZ05 at the
Extension Zone to the northwest. Owing to the glacial
overburden and talus cover it is not presently possible to
determine if the new GZ Zone is a folded continuation of the
Extension Zone. Alternatively, it is also possible the
sulphide mineralisation is fault controlled and a new, strongly
mineralised structure has been discovered.
EXPLORATION ROCK SAMPLE RESULTS FROM GEOCHEMICAL ANOMALIES
During September several of the anomalous areas as defined by
soil-talus sampling within the North Rackla claims were prospected
by Chad Ulansky. Results from
the first 26 of 107 rock samples collected have been
received. Eight of the samples are reported in the GZ Zone
section above and 11 samples are reported in Table 2.
Table 2 presents rock sample results from two discrete anomalies
(G14 and B39). The locations of these anomalies are presented
in the map contained within the July 9,
2020 press release.
The six samples collected from Anomaly G14 were collected along
a 60 metre length and contained elevated gold values of up to 24.40
g/t.
Five samples collected from anomaly B39 stretch over 170 metres
and contain exceptional silver values and elevated copper
contents. These samples average 3,411 g/t (109 ounces per
tonne) silver and 2.73% copper.

The foregoing are most encouraging and these results along with
the additional pending rock sample results will define areas to be
structurally mapped and drilled in 2021.
MAIN ZONE RESULTS
Assay results have been now been received for a total of four
holes drilled from two pads. The pad locations are presented
in Figure 1 and the results are reported below in Table 3.
Hole YKDD20-159 has additional intervals for which assays are still
pending. These results, along with those from additional
holes yet to be analyzed, will be reported when received.

As presented above, multiple mineralized zones were intersected
in hole YKDD20-159 between 530.90 and 575.10 metres, with grades
ranging from 18.72% to 32.38% combined lead and zinc and 41.96 g/t
to 72.85 g/t silver. This extends the depth of the
mineralization to 550 metres below surface with results pending for
disseminated mineralization intersected further down the
hole. As announced on September 29,
2020 mineralization was intersected in the adjacent hole
YKDD20-163 down to a vertical depth of 680 metres.
Zircons from the dyke swarm, illustrated in Figure 1, have been
dated by Dr. Kyle Larsen of UBC
Okanagan at 1.79+/-0.02 billion years. As the dyke swarm
crosscuts the massive sulphides, this means that the mineralization
must be older than 1.79 billion years. This age, as well as
the marine carbonate host rocks, and elevated manganese content are
analogous to large silver-lead-zinc mines such as Broken Hill and
Mount Isa in Australia and the
Sullivan Mine of British
Columbia.
The drill holes reported in this press release were drilled
using HQ (63.5mm) diamond drill bits. If the drill lacked
sufficient power to drill this large core at depth the hole was
reduced to NQ (47.6mm). 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 and prospecting rock samples were
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 and a 250g
split was sent for assay. Quality control procedures included
the insertion of coarse quartz samples to assess the sample
preparation. Silica blanks were inserted along with certified
reference samples. These quality control samples were each
inserted approximately every 20 samples.
ALS Chemex in 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,
zinc or copper values exceeded one percent the Pb-OG62, Zn-OG62 or
Cu-OG62 techniques were used. These have upper limits of 20%
lead, 30% zinc and 50% copper respectively. Samples with lead
and zinc values over these limits are 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. When this was exceeded the Ag-GRA21 technique was
used. Gold was assayed for using Au-ICP22 which has an upper
limit of 10 g/t; where exceeded the Au-GRA22 technique was
used. The over limit analyses (and the over limit – over
limit analyses) contribute to delays in receiving final assay
results.
The technical information and results reported here have been
reviewed by Mr. Chad Ulansky
P.Geol., a Qualified Person under National Instrument
43-101, who is responsible for the technical content of this
release.
