FURTHER GOLD MINERALISATION FROM SPECIMEN HILL
AND COMMENCEMENT OF MOUNT CASSIDY DRILLING
Tectonic Gold plc (TDIM: TTAU), the Intrusive Related Gold System ("IRGS")
explorer, is pleased to announce further drilling success from the December
2020 program at Specimen Hill in Queensland, Australia, and commencement of
drilling at the nearby Mt Cassidy discovery, following a short break from field
work over the Christmas Holiday period.
Specimen Hill Highlights:
* Assays from hole SHRC24 returned with 2m @ 3.69 g/t Au, from 79m.
* Maintains the 100% track record of Tectonic's drill targeting
* Extends the drill tested zone at Specimen Hill to 800m of a 4km+
mineralised corridor
* 500+ samples being pre-screened for assay
* A geological map is provided at this link

* Drilling at Specimen Hill will recommence following the Mt Cassidy program
currently underway
Mount Cassidy Highlights:
* Previous testing returned assays of +30g/t gold
* Tectonic has completed extensive geochemical and deep penetrating
geophysical mapping
* Textbook IRGS system identified which had been overlooked by previous
explorers
* Drilling began on 9 January 2021
* An initial 1,500m is budgeted to test targets down to 200m
Following a 1,500 metre drilling campaign at Mount Cassidy, drilling will
return to Specimen Hill to test the Southern Copper target which returned 16%
copper and 9g/t gold from surface sampling.
Mr. Brett Boynton, Managing Director - Tectonic Gold Plc
"It is extremely encouraging to open the New Year with another gold hit
following the success of the campaign in December. Hole SHRC24 takes us out to
about 800m of the 4km long strike being successfully tested at depth. We sent
material from these first few holes for rapid assay turnaround prior to
Christmas so that we can use them as a baseline to filter the remaining
samples. We now have over 500 samples being prepped that will be scanned with
XRF scanners calibrated to the known assays from December. XRF scanning
provides a quick and cost-effective way to identify the best samples containing
gold/silver/copper mineralisation to send for assay going forward ensuring
efficiencies on time and budget.
This project is already showing the characteristics of a very large system and
to provide some content, we have posted a map to the website at:

20210112SpecimenHill4kmStrike
From the Main Lodes in the North East to Southern Copper in the South West,
Tectonic has mapped a 4km+ strike with detailed geochemistry and deep
penetrating geophysical reconnaissance. It is important to note that the system
remains open at both ends and at depth; and in due course we intend to map it
further. For comparison, the "Super Pit" at Kalgoorlie, one of Australia's most
prolific mines, is 2.6km in length.
Tectonic is the first company to have taken a regional scale approach to
looking at the known gold occurrences at Specimen Hill. The patient years of
fieldwork and analytics, digitising this data and utilising our proprietary
IRGS exploration approach to stitch together a largely "blind" or under cover
system, are now paying off. The drilling completed prior to the December break
has proven up 800m of this 4km long strike with intersections targeted at about
100m depth consistently showing medium to high grade over a few metres within a
wider 5m to 10m+ lower grade halo. We look forward to returning to Specimen
Hill at Southern Copper as soon as we have completed the initial 1,500m at Mt
Cassidy.
The team is very excited to be drilling Mt Cassidy. It is a fantastic
discovery, made possible through our in-house developed Intrusive Related Gold
System exploration IP. This has been well supported over many years by the
Australian Federal Government and we are pleased to be delivering on our
promise to them to make the new generation of Australian gold discoveries and
help drive the gold industry forward.
As soon as we have completed the initial drilling at Mt. Cassidy, we will
relocate back to Specimen Hill and drill Southern Copper at the South Western
end of the strike. This is a new discovery following the 2019 bush fires in the
region clearing the ground for the first time in a generation and allowing our
geologists to survey the area. We were hopeful of a discovery, as our airborne
"SAM Survey" geophysics had shown the Specimen Hill system extended through
this area and we were rewarded with assays above expectations of 16% copper and
9g/t gold from surface sampling.
For the team this is going to be a busy quarter and for investors we expect to
have plenty of news flow from both Specimen Hill and Mount Cassidy."

Samples from the remaining 6 holes have been logged with very similar
characteristics being observed. We expect assays from these holes to return
similar results with gold, silver and copper mineralisation.
The mineralisation is held in a textbook hydrothermal breccia zone which is
tightly controlled within the Andrews Gulley and Specimen Hill shear zones. The
strike of the system that has been mapped and sampled at surface, extending
over 4kms. This is identified to be open in both directions and further
exploration will likely increase this length of the mineralised corridor.
Further drill testing of this mineralised corridor provides evidence of
Tectonic's initial assessment that the Specimen Hill prospect is a large-scale
polymetallic system with multi-million-ounce potential.
About the Specimen Hill Prospect:
Specimen Hill has produced over 8,000ozs of gold from historic small-scale
surface mining with grades reported up to 40g/t Au.
Tectonic Gold has identified a large Intrusive Related Gold System (IRGS)
manifesting as a 4km long mineralised corridor at the Specimen Hill and has
identified the possibility of a much larger system under cover.
Gold, copper and silver mineralisation within the known 4km corridor manifests
itself near surface as a polymetallic, high-sulphidation (HS) system that has
been enriched by late-stage intermediate-low sulphidation (IS-LS) gold
mineralisation. At depth, Tectonic is seeing that this is a gold-copper
porphyry co-incident with a high-temperature magnetite rich core (identified at
Specimen Hill and Southern Copper Targets which are associated with high copper
and gold grades).
Rock chip samples from surface skarn outcrops mapped so far over the area of
18 km2 have returned grades of consistently elevated Au, Ag and Cu.
Tectonic has recently completed a second drilling campaign at Specimen Hill.
All holes have intersected mineralization at depths to over 100m from surface,
validating the continuity of both geology and grade observed at surface.
About the Mount Cassidy Prospect:
The Mount Cassidy prospect is located near Tectonic Gold's flagship Specimen
Hill project, approximately 50km NW of the regional centre of
Rockhampton, Queensland Australia.
A large ovoid 4km2 magmatic hydrothermal IRGS system, confirmed from mineral
chemistry and geophysical research, has been further assessed through a
collaborative research project between CODES and Tectonic Gold.
Gold bearing veins emanating within this porphyry system have been historically
mined with grades of 15g/t Au recorded from selective mining.
Geological mapping of the hydrothermal system at Mount Cassidy has confirmed
classic porphyry style potassic and phyllic alteration over a large area that
has been overprinted by gold bearing fluids emanating from a regional
reidel-style shear system that cross-cuts the prospect.
