Final results from Tin Beetle drilling confirm hub and spoke potential at
Taronga tin project
First Tin PLC ("First Tin"), a tin development company with advanced, low
capex projects in Germany and Australia, is pleased to report that the
remaining assays from its Tin Beetle prospect, approximately 9km from our
advanced Taronga DFS project, have confirmed mineralisation over the entire
2.3km tested to date. This validates the company's 340km(2) tenure in the
Emmaville area as a "Tin District", with excellent potential for satellite
deposits to the large Taronga deposit. Historically, approximately 88,000
tonnes of alluvial tin were mined from within the Emmaville district, the
majority of which came from the Tin Beetle area.
Tin Beetle is one of six additional prospects near Taronga that have potential
for satellite or stand-alone tin mineralisation (Figure 1).
Highlights
· Initial assay results from very wide spaced drilling confirm wide
intervals of tin mineralisation with narrower zones of higher grade
mineralisation
· Significant intercepts include:
o 48m @ 0.18% Sn from 2m incl. 21m @ 0.32% Sn from 2m and 3m @ 0.28% Sn from
42m
o 30m @ 0.10% Sn from surface incl. 7m @ 0.16% Sn from 21m (entire hole
mineralised)
o 18m @ 0.07% Sn from 17m incl. 9m @ 0.10% Sn from 17m
o 78m @ 0.08% Sn from 7m incl. 12m @ 0.11% Sn from 7m and 12m @ 0.13% Sn
from 48m
o 57m @ 0.05% Sn from 62m
o 27m @ 0.08% Sn from 76m incl. 14m @ 0.12% Sn from 77m and 5m @ 0.18% Sn
from 85m
· These intercepts are similar to early drill intercepts at the
main Taronga mineralisation
· Tin Beetle appears to have lower copper and silver content, but
higher zinc content than Taronga
· The Tin Beetle prospect is located approximately 9km southeast of the
main Taronga mineralisation, providing potential for it to be taken by road to
a central milling facility at Taronga following on-site upgrading by crushing
and possible jigging
· If successful, this concept could significantly add to the annual
tin production and/or increase the overall mine life of the Taronga tin
project
First Tin CEO Thomas Buenger said: "We are pleased to announce that this
drilling has proven our thesis that Taronga is part of a tin district rather
than a singular tin occurrence. The recent drill intercepts at Tin Beetle are
similar to early drill intercepts at the main Taronga project.
Tin Beetle, like Taronga, also appears to benefit from extremely favourable,
sheeted vein style, cassiterite mineralisation, with simple mineral processing
characteristics, that outcrops at surface, and could therefore potentially be
mined as an open pit. The confirmation of mineralisation over the entire 2.3km
drilled to date suggests potential for several open pits in the area. This
could significantly improve annual tin output and/or mine life for the Taonga
tin project as a whole.
Follow-up drilling is planned for next year following completion of the
Taronga DFS."
The project is owned by First Tin's 100% owned Australian subsidiary, Taronga
Mines Pty Ltd ("TMPL").
All assay results are presented in Table 1. The true width of intervals is
around half the downhole width. Estimated true widths are included in Table
1.
The drilling targeted a broad area (3km x 0.6km) of mineralisation that had
been mined for alluvial and eluvial tin during the 19(th) and 20(th)
Centuries. It is defined by large workings that have stripped the alluvial
material and then continued into weathered, clayey felsic volcanics with
sheeted greisen veins hosting cassiterite (tin oxide) mineralisation. This was
historically referred to as "soft rock" mineralisation. Four ENE trending
zones of sheeted veining are interpreted from the outlines of workings, tin
geochemistry, mapped areas of veining and limited previous drilling (Figure
2).
The current TMPL drilling has confirmed and extended at depth, mineralisation
identified by previous explorers in the late 1970s and early 1980s. The
mineralisation intersected is variable in thickness and grade and it is
interpreted that several moderately sized higher-grade deposits exist within
the overall very large, low-grade mineralisation system.
One area with good outcropping tin mineralisation has been tested by four
drillholes (TMGBRC001-4) over about 250m of strike in the central part of the
central zone (Figure 2). This has confirmed mineralisation with similar grade
to the main Taronga mineralisation (0.10 to 0.18% Sn) over the entire 250m and
with true widths of between 5m and 25m. This could potentially be mined using
open pit techniques as mineralisation outcrops at surface.
Three other areas have been tested by a single line of drillholes each, and
all of these have returned broad widths of low-grade mineralisation containing
smaller, higher-grade zones, suggesting potential for several open pits in the
district. Drillhole TMGBRC006 returned a very broad mineralised zone of 78m
grading 0.08% Sn, with two higher grade zones of 12m @ 0.11% Sn and 12m @
0.13% Sn. This is beneath the main area of "soft rock" mineralisation mined by
dredges during the 1970s and 1980s (see dredge pits on Figure 2) and provides
a very large target in this area.
TMPL considers the Tin Beetle prospect to be one of several potential
satellite deposits for Taronga, with treatment via preconcentration using
simple crushing and possibly jigging and then trucking the concentrate
approximately 8-9km to Taronga for final processing (Figure 1). If successful,
this concept could either add to annual tin production, increase the overall
mine life after Taronga mineralisation has been exhausted, or both.
It is proposed that a systematic drilling programme be undertaken over the
prospect area, following completion of the Taronga DFS, designed to outline
higher grade, potentially mineable zones within this large mineralisation
system.

Notes to Editors
First Tin 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.
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. Its assets have been de-risked significantly, with
extensive work undertaken to date.
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.
