Final RAB Drill Results from Tibbs Identifies Additional High-Grade Gold at Lower Trench Zone
VANCOUVER, BC

Oct. 6, 2020
/CNW/ -
Tectonic Metals Inc.
(TSXV: TECT; OTCQB: TETOF) ("Tectonic" or the "Company") today announced the final assay
results from the completion of its 3,202 metre ("m"), 27 hole Rotary Air Blast ("RAB") drilling campaign at the Tibbs Gold Project ("Tibbs"). Drilling this summer at
the Lower Trench ("Lower Trench") and Wolverine ("Wolverine") Zones represented the first drill holes at either target since 1997. Results from Lower Trench
include a highlight intercept of 10.78 grams per tonne gold ("g/t Au") over
3.05m
within a broader interval of 4.50 g/t Au over
7.62m
, with gold found in association
with disseminated sulphides in sericite-altered granodiorite and discrete quartz-sulphide veins, identical to the Michigan Zone ("Michigan", additional information
here
) 1.5km to the southeast. Both Lower Trench and Wolverine are believed to represent structural blocks which were initially connected to
Michigan
, where
2019 and 2020 drilling intersected gold in every hole including highlights such as 6.71 g/t Au over
9.14m
and 6.03 g/t Au over
28.95m
. The recognition of
Michigan-style mineralization at Lower Trench indicates that a significant hydrothermal system was active throughout a multi-kilometre structural damage zone,
greatly expanding the potential of both the
Michigan
and Lower Trench targets.
RAB Drilling Highlights and Key Takeaways
Drilling at the Lower Trench target identified Michigan-style mineralization – highlights include:
4.50 g/t Au over
7.62m
including 10.78 g/t Au over
3.05m
(TBRB20-032)
2.38 g/t Au over
3.05m
(TBRB20-032)
0.79 g/t Au over
13.72m
including 2.28 g/t Au over
1.52m
(TBRB20-035)
Mineralized Structures Continue
Mineralization at Lower Trench is identical to
Michigan
but is located 1.5km to the northwest in a separate fault block
Lower Trench represents a ~1km long portion of the Michigan Structural Corridor, offset to the west after the mineralizing event. Mineralization at Lower
Trench is open along trend and at depth
Pogo Geological Model Remains Relevant
Both low and high-angle structures control gold mineralization at Northern Star Resources'
Pogo Mine
("Pogo"), located 35km to the west of Tibbs
Mineralized low-angle structural features observed at Lower Trench, with similar features observed at
Michigan
Recognition of mineralized low-angle features at Lower Trench and
Michigan
suggests an interplay between high-angle faulting and low-angle regional
extension and shearing
Wolverine – Further Work Required
Drilling conducted on ridge top, up-slope of high-tenor gold-in-soil anomalies believed to be transported
Minor gold mineralization encountered, with low arsenic and antimony response
1,000 x
400m
historic gold-in-soil anomaly warrants further work; drilling to date has not explained the size nor tenor of the anomaly
Upcoming Assay Results
Seventymile drilling – 6 zones tested by
2,582m
of RAB drilling - Assays pending
Tibbs Soil Sampling Program - >1,100 soil samples collected at Tibbs, with focus on gneissic rocks in west; ideal Pogo analogues – Interpretations
ongoing
Induced Polarization (IP) geophysical survey at Michigan Zone completed – Results pending
Prospecting and mapping campaigns completed at the Maple Leaf and Mt. Harper Projects - Interpretations pending
Eric Buitenhuis
, VP Exploration, commented,
"Tectonic is encouraged to confirm additional Michigan-style gold mineralization in our final results from our
successful Summer 2020 drill program at Tibbs. Hole TBRB20-032 at Lower Trench returned high-grade gold within a broad, lower-tenor mineralized envelope;
essentially a carbon copy of mineralization drilled by Tectonic at
Michigan
this year, 1.5km to the southeast. Our 2020 drill holes represent the first test in over
20 years at the Lower Trench target and have significantly advanced our understanding of the structural story at Tibbs and the potential of these structurally
controlled gold targets. The identical nature of the mineralization at the
Michigan
and Lower Trench targets suggests a well-developed hydrothermal system,
which we know is capable of producing high-grade gold mineralization in multiple locations."

Tibbs Gold Project – 2020 Drill Strategy
Building upon 2019's exploration success, which included a highlight intercept of 6.03g/t Au over
28.95m
, with Ground Truth America's RAB drill, Tectonic chose to
utilize this cost-effective and rapid drill method to step out on 2019's highlight drill intersection at the Michigan Zone of 6.03 g/t Au over
28.95m
. Drilling in 2020
focused on stepping out from this highlight drill intercept, while also testing for additional Michigan-style structures along a 3km long prospective corridor at the
Lower Trench and Wolverine Zones.
Drilling was conducted as fences of angled holes designed to cross interpreted high-angle mineralized structures. Drill holes were dominantly oriented to the east
or southeast, depending on the zone being drill tested, with dips of 55 degrees to cut the dominantly northwest dipping structures. At Lower Trench, drill holes
were planned to test for near-surface mineralization within a
400m
wide saddle formed by a prominent northeast-trending fault zone. At Wolverine, drill holes were
sited up-slope of gold-in-soil anomalies believed to be transported downhill due to solifluction.
A goal metreage of
2,500m
drilled was outlined prior to the commencement of the drill season. Tectonic significantly exceeded this goal at Tibbs, drilling
3,202m
in total without incurring additional costs. A total of 16 drill holes were completed at Lower Trench (
951m
) and Wolverine (
614m
), for a total of
1,565m
between
the two targets.
Geology and Mineralization – Lower Trench & Wolverine
Drilling was conducted at the Lower Trench and Wolverine Zones, both >1km long, northeast trending structural corridors with associated gold, arsenic, and
antimony anomalism defined by soil and rock geochemistry and air photo lineaments.
At Lower Trench, mineralization exhibits the same geochemical and morphological characteristics as observed at the Michigan Zone, located 1.5km to the
southeast. High-grade mineralization is characterized by quartz-pyrite-arsenopyrite-stibnite veining, with the best drilled intervals consisting nearly entirely of
quartz-sulphide vein material. Low-tenor mineralization consists of strongly sericite-altered granodiorite with disseminated sulphides (pyrite, arsenopyrite and
stibnite). Both Lower Trench and
Michigan
host low-angle diorite sills which pre-date mineralization, the margins of which may focus fluid flow due to rheological
contrast with the host granodiorite. The western portion of Lower Trench hosts high levels of antimony enrichment with lower gold values. This portion of the
Lower Trench target is separated from the eastern drilled area (i.e. holes TBRB20-032, TBRB20-035) by an inferred near-vertical fault, and is upthrown relative
to the eastern block as indicated by the relative orientation of the diorite sills.
Drilling at the Wolverine Zone returned thin intercepts of low tenor gold mineralization (0.67 g/t Au from 51.82-
53.34m
in hole TBRB20-46, 0.57 g/t Au from
4.57-
6.10m
in hole TBRB20-045). Notably the 2020 drilling at Wolverine has indicated that gold mineralization is only weakly associated with arsenic and is not
associated with antimony. The differing geochemical signature defined by the 2020 drilling at Wolverine suggests that the target represents a separate structural
block. Future work at Wolverine will look for the source of the high-tenor gold-in-soil anomaly, which remains unexplained.
Exploration Upside and Next Steps
A follow-up induced polarization ("IP") geophysical survey at the Michigan Zone has now been completed. The goal of the survey was to determine the
geophysical signature of drilled, near-surface mineralization at
Michigan
within the centre of the target and test for a similar signature both at depth and along
strike within the corridor. In addition to the Michigan Zone, an IP line was completed at the Lower and Upper Trench zones to aid in structural interpretation of the
target area. Survey results will be interpreted once received.
Tectonic also completed a comprehensive soil sampling campaign to both infill and expand the historic soil grid over previously untested ground to the west and
east. The goal of the soil program was to generate new exploration targets with a focus on exploring the gneissic rocks in the west of the property, where low-
angle thrust faults have been mapped by previous workers. The interplay of low-angle regional shears and high-angle fault structures as observed at Pogo, where
both styles of structure acted as hydrothermal fluid conduits. The presence of interpreted low-angle structural features at both the Lower Trench and Michigan
Zones at Tibbs suggests that similar relationships may be present within the gneissic rocks just west of these targets.

Quality Assurance and Quality Control procedures include the systematic insertion of blanks and standards into the drill sample string at a rate of approximately
1/10 (10%). In addition, field duplicate samples are systematically collected at a rate of 3 duplicates per 100 samples. Samples are placed in sealed bags and
shipped directly to the Bureau Veritas Laboratories ("BV") preparation facility in
Fairbanks, Alaska
. The analytical work for the 2020 Tibbs RAB drilling program
was performed by BV, an internationally recognized and accredited analytical services provider, which is independent of Tectonic. All RAB drill samples were
prepared using procedure PRP70-250 (crush, split, and pulverize 250g to 200 mesh). Samples were then sent to
Vancouver, Canada
, where they underwent
analysis for gold by method FA430 (30-gram Fire Assay fusion with an atomic absorption finish (AAS). Samples returning >10 g/t Au were re-analyzed using
method FA530-Au (30g Fire Assay with gravimetric finish). Following this, a 0.25g pulp was sent to the
Vancouver
lab for four-acid Inductively Coupled Plasma
Emission Spectrometer analysis for 35 elements using method MA300.
