              Copper Gold Discovery and update from Specimen Hill 
 
Tectonic Gold plc (TDIM: TTAU), the Intrusive Related Gold System ("IRGS") 
explorer, is pleased to announce successful assay results reporting gold and 
copper from recent drill preparation work at its Specimen Hill project in 
Queensland Australia. 
 
Highlights: 
 
  * Rediscovery of "Goldsmith's Reef" with historic +40g/t artisanal gold 
    production 
  * Underground mine face samples from old workings +5.4g/t Au and +1.3% Cu 
  * Provides high grade mid-point continuity between Main Lodes and Southern 
    Copper 
  * A second high grade discovery named "Overshoot" found along strike from 
    Southern Copper 
  * 2.6% Cu returned from assay of exposed mineralisation 
  * Independent structural mapping/modelling of Specimen Hill completed for 
    drill targeting 
  * Drill mobilisation planned for Southern Copper campaign 
 
Mr. Brett Boynton, Managing Director - Tectonic Gold Plc 
 
"We have had a busy restart to the 2021 campaign season with a lot of time back 
on the ground since we demobilised the January drilling program. We are excited 
to be preparing to drill again with a couple of exciting new discoveries. These 
were made while conducting detailed mapping on the Main Lodes to Southern 
Copper strike. This was part of an independent structural modelling with Dr 
Brett Davis of Olinda Gold Structural Geology Consulting. Dr Davis is an 
external expert Newcrest used in their assessment of Greatland Gold. Tectonic 
engaged with Dr Davis to ensure we have the highest calibre validation of our 
projects to replicate Greatland's strategy in partnering with a major gold 
company. 
 
This is our first operations update since the January drilling results. With 
the dry season well underway we expect to have sustained field activity and 
more news flow into the second half of the year." 
 
Specimen Hill Project Update 
 
Tectonic previously mapped a continuous strike from Main Lodes to Southern 
Copper, a distance of over 4km. The focus of the work over the last three 
months has been to increase the resolution of this mapping with on the ground 
surveying, sampling and assaying. This work was conducted over many weeks in 
the field and afforded the technical team the opportunity to take a number of 
independent specialists out to site. 
 
These independent specialists include Dr Brett Davis, who has completed an 
advanced structural model of Specimen Hill which informs our drill targeting. 
Following this the Company has completed a detailed mineralogical study on 2018 
drilling data to validate the blind porphyry under Main Lodes and provide final 
input for deeper drill targeting of this discovery. 
 
During these mapping expeditions, the old workings of Goldsmith's Reef, which 
date back to before World War One, were identified. Small syndicate scale 
underground workings selectively mined high grade veins reporting grades of 
over 40g/t gold. Goldsmiths Reef is an enticing rediscovery as modern mining 
technology now enables large scale open pit mining which could economically 
exploit this mineralisation to a much greater depth than was historically 
possible. 
 
The table below highlights the independent assays from the face samples 
collected during the survey of the underground workings.

Underground geological mapping of veins confirms the continuity of gold and 
copper mineralisation previously mapped on surface. This is an important data 
set as it confirms continuity of mineralisation along strike from previous 
testing at Andrew's Gulley which is approximately halfway between Main Lodes 
and Southern Copper. 
 
A second discovery was made along strike from Southern Copper during site 
preparation for drilling with new access roads being cut. The team have named 
this prospect "Overshoot". This prospect is 3km along strike southwest of 
southern Copper. 
 
Assay results from outcrop sampled showing exciting copper grades are presented 
in the table below.

This methodical approach to infilling data along the corridor from the Main 
Lodes to Southern Copper continued to reinforce Tectonic's expectations of the 
prospectivity of the area. 
 
The Company is now ready to bring the drill rig back to site to tackle depth 
testing at the Southern Copper discovery. 
 
Tectonic has also had extensive additional work completed on validating and 
targeting the feeder at Main Lodes. The blind porphyry discovery has been 
confirmed and will be the focus after drilling Southern Copper. 
 
About the Specimen Hill Prospect: 
 
Specimen Hill is located in a recognised gold producing region of the New 
England Orogen. Tectonic has been systematically exploring the Specimen Hill 
area since it acquired the tenements in 2010, culminating in the definition of 
a significant mineralised corridor. 
 
Specimen Hill has produced over 8,000ozs of gold from historic small-scale 
surface mining with grades reported up to 40g/t Au. 
 
Geophysical analysis and subsequent drill testing of geophysical IP and 
coincident magnetic anomalies in 2018 led Tectonic to the discovery of a 
significant mineralised corridor. 
 
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. Recent and 
ongoing field activities have confirmed that the Main Lodes, Cameron's Lookout, 
Andrew's Gully and Southern Copper prospects are all part of a 4km long 
laterally contiguous and vertically persistent (+500m) gold rich system that is 
contained within a 250m wide corridor. 
 
For comparison the Newcrest owned Cadia East copper-gold deposit in NSW has a 
mineralised zone 2.5 km in length, 600m in width and over 1,900 m in vertical 
extent.
