First Tin PLC

("First Tin" or "the Company")

Trial Blast Successfully Undertaken

 

First Tin PLC (LSE: 1SN), a tin development company with advanced, low capex
projects in Germany and Australia, is pleased to announce that a Trial Blast
at its Taronga Tin Project ("Taronga") in Australia has been successfully
undertaken and the results have been analysed.

The blast was undertaken on 2(nd) October 2024 and the consultants' final
report was received on 28(th) October. All safety procedures were followed and
no safety or community concerns were recorded.

 

Key findings include:

 

·     Drilling showed excellent penetration rates aided by the vertical
nature of the fracture sets.  A total of 221.5m was completed within 6 hours.

·     Powder factors of 0.3, 0.5 and 0.8 were trialled based on 0.8 SG
ANFO (Ammonium Nitrate Fuel Oil).

·     All powder factors showed excellent breakage to sizes less than
400mm.

·     The consultants recommended that a powder factor of 0.5 be used
for production holes at the start of operations, with 0.3 used for batter
holes in trim shots. It was suggested that a powder factor of 0.3 could be
trialled once mining has commenced.

·     This confirms the powder factor used in the Definitive Feasibility
Study ("DFS") is correct.

·     Two Geophone style blast monitors were placed at the nearby
communications tower (500m from the blast site) and 243m in the opposite
direction from the blast site.  The trigger points were set at 0.5mm/s (PPV)
and 85db overpressure (noise).  The only recorded vibration was at the
closest monitor 243m from the blast site and no overpressure noise was
recorded.

 

 

 

First Tin CEO, Bill Scotting commented:

 

"The trial blast was a great success and reinforces the technical viability of
our Taronga project. It confirms that the powder factors used in the DFS
produce excellent fragmentation and that further trials using even lower
powder factors could result in significant operating cost savings.

 

Our monitoring also confirmed acceptable vibration and noise from the trial,
demonstrating our commitment to safety and minimal community impact. This data
is currently being modelled as part of the preparation of Taronga's
Environmental Impact Statement.

 

The blasted rock also provided an opportunity to collect another bulk sample
for our continuing metallurgical testwork programme, with samples more closely
representing the actual run of mine blasted material. ALS Burnie in Tasmania
will conduct metallurgical testing on these samples.

 

These insights are invaluable as we advance our Taronga asset toward
production."

Notes to Editors

First Tin PLC is an ethical, reliable, and sustainable tin production company
led by a team of renowned tin specialists. The Company is focused on becoming
a tin supplier in conflict-free, low political risk jurisdictions through the
rapid development of high value, low capex tin assets in Germany and
Australia, which have been de-risked significantly, with extensive work
undertaken to date.

Tin is a critical metal, vital in any plan to decarbonise and electrify the
world, yet Europe has very little supply. Rising demand, together with
shortages, is expected to lead tin to experience sustained deficit markets for
the foreseeable future.

First Tin's goal is to use best-in-class environmental standards to bring two
tin mines into production in three years, providing provenance of supply to
support the current global clean energy and technological revolutions.
