Reconnaissance Drilling Confirms Shear Zone
Model and Identifies Targets for Follow-Up
VANCOUVER, BC, Nov. 12, 2020
/CNW/ - Tectonic Metals Inc. (TSX-V: TECT; OTCQB:
TETOF) ("Tectonic" or the "Company") today announced the
results of its 2,587 metre ("m"), 26-hole Rotary Air Blast ("RAB")
drilling campaign at the Seventymile Gold Project ("Seventymile")
in eastern interior Alaska.
Drilling focused on the 8 kilometre ("km") long Flume orogenic gold
trend ("Flume Trend"), located in the northwestern region of
Seventymile's underexplored 40 km long late Paleozoic greenstone
belt. The reconnaissance drill program tested high-tenor
gold-in-soil and top-of-bedrock anomalies situated above
interpreted shear zones along lithological contacts. In addition,
step-out drilling was completed testing historically known
mineralization along strike. Structurally controlled mineralization
was intersected where predicted by Tectonic's new structural
interpretation of Seventymile with highlight intercepts of 2.07
grams per tonne gold ("g/t Au") over 6.10m at the previously undrilled
Flume-Bonanza Zone ("Flume-Bonanza"), 1.37 g/t Au over
19.81m at the Bonanza Zone
("Bonanza"), and 1.20 g/t Au over 4.57m at the Flanders Zone ("Flanders").
Additionally, an infill hole testing extensional, tension-gash
quartz-pyrite-arsenopyrite veins at Flanders returned a highlight result of
4.38 g/t Au over 6.10m.
Anomalous gold mineralization was intersected in all holes which
successfully tested these newly-defined shear-hosted targets along
a total strike length of 6 km, validating Tectonic's targeting
strategy and indicating the presence of a robust hydrothermal
system.
Eric Buitenhuis, VP Exploration,
commented, "Tectonic is pleased to report exciting new results
from our first drilling campaign at Seventymile, the first drill
holes at the property in twenty years, and the first to test
Tectonic's shear zone gold model. The 2020 RAB campaign was
executed as a targeted, three-week drill program designed to test
six of our priority targets within the 8 km long Flume Trend, which
is just a small portion of greenstone within the broader 40 km long
Seventymile Terrane held by Tectonic. Tectonic successfully
confirmed our hypothesis of previously unknown, shear-hosted gold
mineralization directly below our 2018 and 2019 soil and
top-of-bedrock anomalies. This reconnaissance drill program
confirms not only that these structures carry gold mineralization,
but that a previously unrecognized lithological control exists at
Bonanza, where a buried and blind mafic tuff unit returned
consistent gold mineralization at depth with no known surface
expression. Our 2020 RAB program has now identified targets
warranting aggressive follow up in the future."

-
- 4.38 g/t Au over 6.10m
including 12.0 g/t Au over 1.52m at Flanders in low-angle tension gash veins
adjacent to the newly defined shear zones
- Tension veins are hosted by high-Mg basalt immediately north of
the shear zones, and remain open for expansion along strike and
down-dip
- Relationship between shears and tension veins is yet to be
determined, with the possible intersection between the two
structures presenting a priority drill target
- Shear-Zone Gold Model Confirmed
-
- Tectonic's RAB drilling confirms that mineralized shears are
present beyond the limits of historical drilling at Flanders as well as throughout the 8 km long
Flume Trend

lithologic contacts, with lithological control observed as an
increase in grade within mineralized basalts and mafic tuffs
- Expansion Potential at All Zones
-
- Targets exhibit kilometre-scale strike potential, with only
limited RAB drilling at each target
- All targets were successfully drill tested, though drilling
difficulties resulted in seven drill holes at Flanders, Flume and Flume-Bonanza being
abandoned
- Additional Results Pending
-
- Mapping and Prospecting were conducted across the entire 40 km
long Seventymile property to identify new targets for possible
reconnaissance drilling in 2021
- Assay results for 82 rock samples collected during the 3-week
program are currently being reviewed and interpreted

Geology and Mineralization
Flanders Zone – Shear-Hosted Mineralization
Drilling at Flanders has
identified structurally controlled gold mineralization hosted by
interpreted shear zones found at steeply south-dipping rock
contacts (the Flanders Shear Zone). Drilling primarily targeted an
interpreted shear zone found at the contact between a distinct
iron-rich mafic tuff and a succession of volcaniclastic rocks and
mixed sediments which strike to the southeast and dip steeply to
moderately to the southwest. Extensive alteration of the mafic tuff
and surrounding sediment is found in areas of gold mineralization,
with gold spatially associated with the mafic tuff.
Gold mineralization is associated with increased arsenic
content, and consists of pyrite and arsenopyrite, with minor quartz
chips noted in the RAB chip trays. Highlight intercepts from these
structurally controlled intervals include 1.20 g/t Au over
4.57m in hole SMRB20-009, 0.82
g/t Au over 4.57m in hole
SMRB20-002, and 0.50 g/t Au over 12.19m in hole SMRB20-010. Notably, hole
SMRB20-007 recorded peak intercepts of 0.62 g/t Au over
30.48m, 0.42 g/t Au over
21.34m, and 0.45 g/t Au over
15.24m, although structural
orientation and true width is not known at this time.
Flanders Zone – Tension Veins
A single hole was drilled approximately 80m north of the Flanders Shear Zone in the
historically drilled portion of Flanders, where previous operators focused on
drill testing two outcropping, high-grade, shallow dipping,
discrete quartz veins within a distinctive basalt unit (high Fe,
low Mg) of the Seventymile Terrane. Hole SMRB20-025 was drilled to
test the western portion of the tension vein system as an infill
hole on 25m spacing. The hole drilled
through both veins where expected, returning an intercept of
1.51 g/t Au over 6.10m in the
upper vein, and two separate vein intercepts where the lower vein
was expected: 2.03 g/t Au over 1.52m followed by 4.38 g/t Au over
6.10m, including 12.0 g/t Au over
1.52m.
East Flanders Zone – Structural Continuity
Three holes were drilled at East
Flanders, located 1.4 km east of the main Flanders Area on a ridgetop, separated by the
Deep Creek drainage. Drilling confirmed an interpreted shear zone
at the contact between the southern volcaniclastic assemblage and
Seventymile Terrane mafic rocks, as observed at the Flanders Shear
Zone. Drilling encountered argillite and mafic tuff within the
volcaniclastic assemblage, in contact with ultramafic rocks and
high Mg basalts of the Seventymile Terrane in the north. The mafic
tuff exhibited extensive and pervasive alteration similar to that
observed at Flanders, 1.4 km to
the west, with gold intersected adjacent to the contact zone and
within the tuff. Gold intercepts included 0.78 g/t Au over
4.57m in hole SMRB20-011, and
0.63 g/t Au over 6.10m in hole
SMRB20-013, a 100m step out to the
west of SMRB20-011. Strong alteration and arsenic anomalism were
detected within the ultramafic rocks to the north in hole
SMRB20-012, though only slightly anomalous gold was found.
Bonanza Zone – Blind Mineralization at Depth
Two holes were drilled at Bonanza, located 3.0 km west of
Flanders, where a strong surface
gold expression coincides with a sheared, faulted contact between
volcaniclastic sediments in the south and Seventymile Assemblage
mafic and ultramafic rocks in the north. Drilling was designed to
test the contact zone by stepping 100m east of known historic mineralization to
test top-of-bedrock and soil anomalies identified in 2019.
Tectonic's 2020 drill hole SMRB20-015 succeeded in intersecting a
broad zone of mineralization and alteration within tuffaceous
sediments adjacent to the contact with the mafic rocks beginning at
22.86m down hole. Two gold zones were
intersected consisting of an upper interval of 0.49 g/t Au over
6.10m, followed by a lower
interval from 32.00 to 42.67m running
0.36 g/t Au over 10.67m.
Hole SMRB20-014 targeted an enigmatic interval of mineralized
mafic tuff intersected by historic drilling which does not outcrop
at surface (1.34 g/t Au over 44.20m – Hole FC1990-04). The mineralized
mafic tuff was encountered in SMRB20-014, with an interval of
1.37 g/t Au over 19.81m, including
3.01 g/t Au over 4.57m,
intersected beginning at 161.54m down
hole. Based on Tectonic's 2020 interpretation, the mafic tuff
appears to be oriented near vertical, suggesting the historic hole
was drilled down the unit or structure. The mafic tuff hosting this
mineralization appears to be similar to the mafic tuff observed at
Flanders. This unit does not
outcrop but may come to surface south of the historic drill collars
in terrain covered by permafrost.
Flume-Bonanza Zone – First Ever Drill Holes
Flume-Bonanza is located 1.1 km west of Bonanza and consists of
a gently north sloping, permafrost-covered plateau with no outcrop
present. Significant soil and Geoprobe top-of-bedrock gold
anomalies cover >800m of potential
strike along what is interpreted as a repeated section of
sediments, basalts, and ultramafic rocks. A total of 300.8m of drilling in five holes was conducted at
Flume-Bonanza, however only hole SMRB20-017 was successfully
completed to a depth of 201.2m due to
poor ground conditions.
Hole SMRB20-017 intersected gold mineralization in two separate
structures, both found within argillites at or proximal to the
contacts of the repeated ultramafic units. The first zone
intersected 0.44 g/t Au over 13.72m from a down hole depth of 16.76m. The second mineralized structure
contained 2.07 g/t Au over 6.10m, beginning at a down-hole depth of
155.45m. Results from hole SMRB20-017
indicate that two main mineralized structures exist at
Flume-Bonanza, with a single hole piercing both. Attempts to step
out from these intercepts were unsuccessful due to poor ground
conditions.
Exploration Upside and Next Steps
Tectonic's reconnaissance RAB drilling program successfully
tested top-of-bedrock gold anomalies across a >8 km long target
area, identifying the "centre of gravity" of the Flume Trend for
follow up in 2021. Drilling has confirmed the presence of gold
mineralization at rock contacts as interpreted, tied top-of-bedrock
anomalies to subsurface structures, revealed a previously
unrecognized lithologically-controlled gold zone and demonstrated
significant expansion potential of the hydrothermal system at
Seventymile. Five of six zones RAB tested in 2020 warrant diamond
drill follow-up to both expand and refine the newly defined
anomalies while also obtaining structural data from oriented drill
core. Each target exhibits scale potential in excess of 1 km and
remains open along strike, especially where permafrost cover
obscures and masks the surface expression of mineralization.
Additionally, high-grade quartz vein mineralization was confirmed
at the historically drilled region of Flanders, which remains open for expansion to
the north, west and east.
Beyond the 8 km long Flume Trend, Tectonic completed a
three-week mapping and prospecting program along the entire
Seventymile property, covering over 40 km of northwest-southeast
trending prospective greenstone leased from Doyon, Ltd. by
Tectonic. Mapping crews followed up on limited ridge and spur soil
sampling completed in 1990, with the goal of identifying additional
shear-hosted exploration targets for detailed soil or Geoprobe
top-of-bedrock sampling follow up. Results from the mapping program
are pending and will be reported on at a later date.
