Drilling update from MOUNT CASSIDY Project
Tectonic Gold plc (TDIM: TTAU), the specialist Intrusive Related Gold System (&
#65533;��IRGS") explorer, is pleased to announce further progress
of the January 2021 drill program at Mount Cassidy, in Queensland, Australia.
Mount Cassidy Highlights:
* 7 Holes completed for 778m, all intersecting gold bearing sulphides
* Maintains our 100% targeting accuracy record
* Previous surface sampling returned assays of +30g/t gold
* Historic mining records show +15g/t gold processed
* Textbook IRGS system confirmed
* Incident free campaign extending our perfect safety record
Mr. Brett Boynton, Managing Director - Tectonic Gold Plc commented:
"We are very encouraged with the visual review of samples from the drilling at
Mt Cassidy so far. The team has completed 7 holes with mineralisation
intersected in every hole, maintaining our perfect record in drill targeting.
We know from our extensive surface sampling and historic mining records, that
high grade gold at Cassidy is associated with pyrites, which we have picked up
in all of the holes to date.
We have a strict safety-first policy, so with a major weather system nearby we
have put drilling on hold temporarily with 4 holes to go. From drilling
completed thus far, we have sufficient sampling to give us an excellent data
set for our initial proofing analysis. Mt. Cassidy is an important project as
Tectonic have made a discovery here which further justifies our IRGS
methodology and advanced exploration technologies used to identify a system
that had very limited surface expression.
We have tied together a number of disparate, historic, and artisanal scale
operations which we tested with a broad soil sampling program which has
provided indications that a large system might tie it together. We have
followed this work up with an innovative, deep penetrating, geophysics survey
that showed the structure of a major undercover system. Hitting mineralisation
at depth in our reconnaissance drilling program is a confirmation of many years
of field programmes; we are slowly putting this jigsaw puzzle together and we
are extremely excited to have samples in the lab and ready for assay.
Mt. Cassidy gives us a rapidly advancing follow-on project which will become
the focus should we progress our plans to partner on or sell down our nearby
Specimen Hill project.
We have fielded a lot of interest following our announcement that drilling had
begun at Mt Cassidy, so have provided a detailed summary of each of the holes
below to share some of our thinking and how we are working this project."
Exploration Update:
The January 2021 drilling campaign at the Mount Cassidy Prospect completed 7 of
a planned 11 holes with 4 holes postponed due to weather.

Samples have all been collected and logged and are in the laboratory for
processing. Assay results will be reported in due course.
Sulphides have been successfully intersected in every hole that was drilled.

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.
