("Empire" or "the
Company")
Major
Drilling Campaign to Commence at Pitfield:
Targeting
High-Grade Zones Within the Weathered, Titanium-Rich Surface
Deposit
Empire Metals Limited (LON:
EEE), the AIM-listed resource exploration
and development company, is pleased to
announce the commencement of the next major drilling campaign at
the Thomas and Cosgrove Prospects, within the Pitfield Project in
Western Australia ('Pitfield' or
the 'Project'). The planned campaign consists of 84 Air Core
('AC') drillholes for a
total 4,340m drilled, that will both test the extent of, and bulk
sample, the high-grade zones of titanium mineralisation that were
recently discovered within the strongly weathered cap covering this
giant, titanium-rich mineral system.
Highlights
·
The drilling targets priority areas containing
thick, strongly weathered zones of high-grade titanium
mineralisation, these having been identified from previous Reverse
Circulation ('RC') and Diamond Core ('DD') drillholes and which
show average grades of over 6% TiO2 and intervals as
high as 18% TiO2.
·
Recent XRD analysis has confirmed that the mineral
assemblage within these high-grade weathered zones is primarily
high-purity titanium dioxide minerals, anatase and
rutile.
·
Drilling is planned on a 100m by 100m grid, to an
average depth of around 50m, and will provide up to 80 tonnes of
bulk metallurgical sample from both of the two
prospects.
·
The combined drill targets cover over 60 hectares
of mineralised weathered cap and were selected on the basis of
three key parameters: high-purity TiO2 mineral
assemblage, high titanium grades and significant depth of
weathering. Metallurgical samples derived from this drill
programme will be representative of a significant mineral
inventory.
·
The bulk samples will enable the rapid upscaling of
metallurgical test work to allow production scale testing of
gravity and flotation circuits ahead of a large-scale product
development trial, aimed at providing high-quality titanium product
samples for potential customer evaluation.
·
The AC drillholes will be sub-sampled on 2m
intervals, and geochemically analysed, these data will provide the
basis for geological modelling which will greatly assist in, and
expedite the development of, a Mineral Resource Estimate
('MRE').
Shaun Bunn, Managing Director, said:
"I am pleased to
announce the commencement of this very important AC drilling
campaign that provides not only the bulk metallurgical samples to
enable a significant scale-up of our metallurgical test work
programme, but also represents the next phase of defining a Mineral
Resource Estimate for Pitfield. The drilling covers an area of
around 30 hectares at each of the Thomas and Cosgrove prospects, to
a targeted depth of around 50m, this being the average depth of the
weathering profile based on previous drilling results from within
the area.
"Drilling is expected to be completed in a short period of
time, given the soft, friable nature of the weathered zone.
Sub-sampling of the drillholes and geochemical analysis will be the
first priority and this will take a few weeks to turnaround.
Delivery of the bulk metallurgical samples to the processing
laboratory will follow and we anticipate moving to a large scale
metallurgical testwork programme around
May-June."
Air Core
Drilling Programme
The planned campaign consists of 84
AC drillholes for a total 4,340m drilled, which will both test the
extent of, and bulk sample, the high-grade zones of titanium
mineralisation that were recently discovered within the strongly
weathered cap covering this giant, titanium-rich mineral
system. This AC drill programme will be funded from the
Company's existing cash reserves.
The drilling is targeting high-grade priority
areas within the Cosgrove and Thomas Prospects and is scheduled to
commence late February and run for a two-to-three-week
period.
Air core drilling is a drilling method that
uses compressed air to flush cuttings out of the borehole. It's a
cost-effective and efficient drilling method that's commonly used
for shallow exploration projects. The use of AC drill rigs will
enable large quantities of metallurgical bulk samples to be
collected quickly and cost effectively, these samples will allow
the Company to rapidly advance and upscale the process development
test work programme.
The location and spacing of the planned 84 AC
drillholes has also been designed to assist with the Company's MRE
preparation. The programme consists of 40 holes at each of the
Cosgrove and Thomas Prospects on 100m x 100m drillhole-spaced
grids, with an average forecast depth of 51.5m, for a total of
4,125m. Additional holes may be added to further defined the
consistency of the deposit. Two additional holes at each
prospect are planned as "twin holes", designed to validate the
geological and assay data quality of the AC holes, focusing on the
weathered portion of the existing 3 RC drillholes and 1 diamond
core drillhole in the target areas. The average planned depth for
each of the four twin holes is 54m for a total of 215m. Pending the
quality of the results from the twinning of the 3 RC drillholes and
the diamond core drillhole, the Company expects to be able to
utilise the geological and assay data from the campaign towards the
expedited development of a maiden MRE
The targeted drilling areas contain thick,
strongly weathered zones of high-grade titanium mineralisation,
these having been identified from previous RC and Diamond Core
drillholes and which show average grades of over 6% TiO2
and intervals as high as 18% TiO2 (refer Figure
1).

prior drill holes
and two new drilling target areas within the Cosgrove and Thomas
Prospects.
Cosgrove
Prospect
At Cosgrove, the drilling is focused on a
priority area which is approximately 500m by 600m (refer Figure 2).
The weathered zone interval width and average assay grades from the
two previous drill holes located within the Cosgrove priority area
are 48m at 6.50% TiO2 [RC23COS010] and 63m at 6.13%
TiO2 [DD24COS004], while nearby drill holes have similar
depths and high-grades (refer Table 1 for full details).
The depth of weathering of the Cosgrove
priority drill area was shown to be consistently thick and contains
high-grade intervals of mineralisation of up to 17.97%
TiO2.
There are also broad zones of high-grade
mineralisation close to surface, for example 10m at 9.56%
TiO2 from 10m [RC23COS010] and 7.7m at 11.52%
TiO2 from 14.9m [DD24COS004]. These near-surface
areas are also shown to hold the highest percentage of the most
important titanium bearing minerals, anatase and rutile, which will
form the primary feedstock for the upscaled metallurgical test work
programme.

priority area.
Thomas
Prospect
At Thomas, the drilling is focused on a
priority area which is approximately 300m by 1,000m (refer Figure
3). The weathered zone interval width and average assay grades from
the two previous drill holes located within the Thomas priority
area are 72m at 6.75% TiO2 [RC24TOM021] and 54m at 7.02%
TiO2 [RC24TOM022]. Nearby drill holes have similar
depths and high-grades (refer Table 1). What is important to note
in the Thomas priority area is that the depth of weathering is
consistently deeper than the Cosgrove priority area, having been
modelled down to 76m from surface.
There are also broad zones of higher grade
mineralisation close to surface, for example 8m at 8.54%
TiO2 from 4m [RC24TOM022] and 8m at 9.03%
TiO2 from 4m [RC24TOM021]. As in the case of the
Cosgrove priority area the near-surface deposit at the Thomas
priority area also contains a high percentage of the key titanium
bearing minerals, anatase and rutile.

Metallurgical
Test Programme
The AC drilling programme will provide several
large bulk samples from high-grade zones of titanium mineralisation
that have been previously identified within the weathered profile
across the Cosgrove and Thomas Prospects. Producing
metallurgical testing samples of this size and nature will
facilitate important test work aimed at confirming mineral
separation and titanium extraction characteristics,
including:
- scale-up and
optimisation of mineral separation techniques, such as gravity and
flotation, which are already looking promising at small
scale;
- testing of
comminution techniques and mineral concentration methods that are
not easily scaled down to bench scale;
- conduct a
semi-continuous piloting run on the mineral separation flowsheet to
produce a large, bulk mineral concentrate sample;
- comparative
testing of operating conditions in the titanium leach extraction
and precipitation stages, using the bulk concentrate; conduct
further purification and refining testwork to deliver high-purity
TiO2 products; and
- produce a
TiO2 product suitable for industry players
to test product suitability for chloride pigment and Ti sponge
metal feedstock.
The Pitfield
Titanium Project
Located within the Mid-West region of Western
Australia, near the northern wheatbelt town of Three Springs, the
Pitfield titanium project lies 313km north of Perth and 156km
southeast of Geraldton, the Mid West region's capital and major
port. Western Australia is ranked as one of the top mining
jurisdictions in the world according to the Fraser Institute's
Investment Attractiveness Index published in 2023, and has
mining-friendly policies, stable government, transparency, and
advanced technology expertise. Pitfield has existing connections to
port (both road & rail), HV power substations, and is nearby to
natural gas pipelines as well as a green energy hydrogen fuel hub,
which is under planning and development (refer Figure
4).

About Empire Metals
Limited
Empire Metals is an AIM-listed
exploration and resource development company (LON: EEE) with a
primary focus on developing Pitfield, an emerging giant titanium
project in Western Australia.
The high-grade titanium discovery at
Pitfield is of unprecedented scale, with airborne surveys
identifying a massive, coincident gravity and magnetics anomaly
extending over 40km by 8km by 5km deep. Drill results have
indicated excellent continuity in grades and consistency of the
mineralised beds and confirm that the sandstone beds hold the
higher-grade titanium dioxide (TiO₂) values within the interbedded
succession of sandstones, siltstones and conglomerates. The Company
is focused on two key prospects (Cosgrove and Thomas), which have
been identified as having thick, high-grade, near-surface, bedded
TiO₂ mineralisation, each being over 7km in strike
length.
An Exploration Target* for Pitfield
was declared in 2024, covering the Thomas and Cosgrove mineral
prospects, and was estimated to contain between 26.4 to 32.2
billion tonnes with a grade range of 4.5 to 5.5%
TiO2. Included within the total Exploration
Target* is a subset that covers the weathered sandstone zone, which
extends from surface to an average vertical depth of 30m to 40m and
is estimated to contain between 4.0 to 4.9 billion tonnes with a
grade range of 4.8 to 5.9% TiO2.
The Exploration Target* covers an
area less than 20% of the overall mineral system at Pitfield which
demonstrates the potential for significant further
upside.
Empire is now accelerating the
economic development of Pitfield, with a vision to produce a
high-value titanium metal or pigment quality product at Pitfield,
to realise the full value potential of this exceptional
deposit.
The Company also has two further
exploration projects in Australia; the Eclipse Project and the
Walton Project in Western Australia, in addition to three precious
metals projects located in a historically high-grade gold producing
region of Austria.
*The potential quantity and grade of
the Exploration Target is conceptual in nature. There has been
insufficient exploration to estimate a Mineral Resource and it is
uncertain if further exploration will result in the estimation of a
Mineral Resource.
