Assays
and Progress on Gold Tailings Projects
Fulcrum Metals plc (LON: FMET), a
company focused on mineral exploration and development in Canada,
is pleased to provide an update on the Company's
Teck-Hughes and Sylvanite gold tailings projects
located in the Kirkland Lake area of Ontario,
Canada.
Highlights
·
Teck-Hughes Gold
Tailings Project
o Four
new auger sites report average 0.65g/t gold, 1.3g/t silver and
13g/t tellurium
o Silver and tellurium - Canada recognises tellurium as a
critical mineral - this had not been assayed previously. The Board
of Fulcrum believe this could offer by-credits and enhance the
project further
o Ongoing auger hole sampling targeting 16 site locations
(Figure 1 below)
·
Sylvanite Gold
Tailings Project
o Six
new auger sites report average 0.58g/t gold, 1.1g/t silver and
13.9g/t tellurium
o Average of 0.56g/t gold, 1.1g/t silver and 14.6g/t tellurium
from duplicates of seven resampled sites sent to Extrakt Process
Solutions LLC ("Extrakt") for phase 1 processing test work, broadly
in line with historically reported gold grades
o Silver and tellurium had only been sampled as part of bulk
concentrating testing in 2012 with in situ grades of 1g/t and
7.5g/t respectively. Concentrating achieved 21.5g/t gold, 14.1g/t
silver and 152g/t tellurium. Concentrating and by-credits could
enhance the project further
o Phase 1 testing continues using Extrakt's proprietary
technology on tailings material samples from eight site locations -
including metallurgical, ICP assay (minimum 40 elements, including
gold), XRD mineralogical analysis and batch leach
testing
·
Mechanised auger hole exploration permits under
preparation to allow systematic drilling of the tailing orebodies
to augment work streams and resource modelling
·
Fulcrum management conducted successful site
visits to the Teck-Hughes and Sylvanite sites, and meetings with
key stakeholders who emphasised support in advancing both gold
tailings projects
Ryan Mee, Chief Executive Office of Fulcrum,
commented:
"To put it simply the detailed work in progress at the gold
tailings projects is delivering. Assay results from additional
areas of the tailing orebodies prove abundant gold at surface and
new silver and tellurium grades which provide potentially valuable
by-products. It is worth noting that the tellurium grades of
approximately 14g/t are nearly twice the grade of those reported in
the historic sampling for concentrate testing at Sylvanite in 2012
which ultimately achieved 152g/t. This, combined with the fact that
tellurium is recognised as a critical mineral in Canada, could also
offer further benefit to the projects.
"When evaluating the gold and other minerals present in these
tailings deposits, it's important to remember that these deposits
sit at surface and consist of millions of tonnes of 'fine' tailings
that have already been mined and milled. This presents a
significant advantage: there is no need for new discoveries,
sub-surface infrastructure, or mine construction. Instead, we are
confirming accessible, surface-level gold resources and
demonstrating our capability to efficiently extract gold from them.
Our workstreams are specifically designed to accomplish this in a
cost and time-effective manner.
"Fulcrum is an early mover in targeting reprocessing of
historic tailings and our work to date through auger drilling, the
excellent leach test work with Extrakt and the positive government
and community engagement is putting the company in a strong
position. We look forward to providing further updates in due
course."
Teck-Hughes Tailings
Project
Table 1 below presents the results
of the additional four auger sites, which are also included in
Figure 1. The objective of these holes is to confirm gold grades in
preparation for a wider systematic auger hole program. They were
not completed to the base of the tailings. Silver and tellurium had
not been assayed for previously, and the Company believes that the
grades shown could potentially offer the project multi-mineral and
concentrate potential.

Auger hole sampling across an
additional 16 sites (shown in Figure 1 below) is now underway to
further expand the data set and contribute towards a wider resource
auger hole program. Given the silver and tellurium results at the
new four auger sites, once completed these samples will be sent to
Actlabs in Timmins for gold, silver and tellurium assay.

Sylvanite Tailings
Project
Table 2 below presents the results
of six new auger sites which are also shown in Figure 2. The
objective of the 'S.low Bas' holes is to establish gold grades for
a wider systematic auger hole program. They were not completed to
the base of the tailings. The 'BH' holes are duplicates of samples
sent to Extrakt for phase 1 testing and provide the Company with
additional verifiable data to the program. Silver and tellurium had
only been assayed as part of bulk sample concentrate testing in
2012 with grades reported of 1g/t silver and 7.5g/t tellurium. The
Company believes that the grades shown could potentially offer the
project multi-mineral and concentrate potential.

All of the samples relating to the
above 'BH' auger sites are with Extrakt for a full range of testing
using its leach technology in addition to metallurgical, ICP
(minimum 40 elements, including gold), XRD mineralogical analysis
and batch leach testing. This work is now underway with the results
of the test work anticipated to be before the end of
2024.
Figure 2 - Sylvanite historic and recent auger holes with gold
grades
Recently, Fulcrum's management
conducted site visits to Teck-Hughes and Sylvanite and met with key
stakeholders including sub-contractors, potential in-country
management and consultants, potential collaborative partners and
local communities. The engagement was extremely positive with
support and interest offered from all parties. From the meetings,
important information was curated to enable the Company to
accelerate its program of development across its tailings projects.
Further information as appropriate will be provided in due
course.
Further information
Licensing discussions with Extrakt
The Company announced mining option
agreements to acquire the Teck-Hughes tailings project on 30
November 2023 and the Sylvanite tailings project on 10 April 2024.
Since the announcement on 30 November 2023, Fulcrum has been
advancing discussions with Extrakt, a sustainable technology
company which uses separation technology to extract metals from
tailings without the use of cyanide, about the licensing of its
proprietary technology including term sheet stage discussions in
relation to a wider licencing framework in Ontario.
On 24 January 2024, Fulcrum entered
into a phased development programme with Extrakt for the
Teck-Hughes tailings project, and on 12 June 2024 for the Sylvanite
Tailings Project.
Phased development programme
Phase 1 - High-Level Gold
Recovery Investigation
Initial high-level gold recovery
investigations serve as the primary evaluation of the enhanced gold
recovery achievable through Extrakt technology. The data collected
in this phase will validate and refine the technology and support
Phase 2.
Phase 2 - Conceptual
Study
The conceptual study will provide
Fulcrum with a first insight into the project's viability using the
information developed during Phase 1. According to the information
available, the accuracy level of the study is approximately ±
50%.
Phase 3 - Laboratory Test
Work
More detailed test work is required
to optimise some of the leach parameters as well as develop
necessary scale-up parameters for all the major equipment of the
operation.
Phase 4 - Economic Assessment
Study
The economic assessment study will
provide a more accurate insight into the project viability using
the more detailed test work results for the whole of the flowsheet.
The accuracy of the study is aimed to be at a pre-feasibility level
of ± 30% accuracy level.
Teck-Hughes Gold Tailings Project Background
Historic sampling and auger drilling
campaigns were initially conducted at the Project in 1980 and most
recently between 2018 and 2022, which produced a non-complaint
resource estimate.
As part of the most recent campaign,
a total of 95 auger samples were collected and assayed at Actlabs
in Timmins. The highest sample assayed 1.73g/tonne Au with 72 of the 95
samples assaying between 0.5 to
0.8 g/tonne Au. The average was 0.66g/tonne Au.
Based on the data from this
sampling, along with that of the drill program from 1980, an
estimate of the tonnage was calculated over the north, west and
northeast arm of the tailings. This totalled 6,531,300 tonnes of material at
0.66g/tonne Au for
138,460 ounces contained
Au*.
Sylvanite Gold Mine Tailings Project
Background
A 1986 report filed on the property
estimated a tailings resource of 4.52 million tons (4.14 million tonnes) grading
0.015 oz/ton Au (0.47g/t
Au) containing 67,051 ounces of gold*.
In 2008 a 30m x 25m sampling grid
was established with drilling to base of tailings to obtain samples
for assay and recovery test work - 1.22m sample length in 149 holes
totalling 926.6m - with a maximum tailings thickness of 12.2m
reported. An average grade of 0.541g/t Au was reported in the 20
holes fully sampled and assayed. In addition to this cyanide
leaching tests achieved on average c.30% gold recovery which, when
combined with a roasting process improved gold recovery to c.60%.
Thiosulfate leaching achieved c.25% gold recovery rates.
In 2012 metallurgical work and a
pilot plant campaign work by Advanced Reclaim International
demonstrated a viable and scalable mineral processing approach to
recover saleable gold containing concentrate and leaving
reprocessed tailings with properties suitable for use as a subsoil
when restoring vegetation cover on the former tailings area. The
cleaner concentrate achieved 21.5g/t gold, 14.1g/t silver and
152g/t Tellurium.
*The historic non-compliant resource estimates cited in this
release have not been verified by Fulcrum and the tailings bodies
require detailed follow-up sampling along with appropriate QAQC and
estimation by an independent qualified resource geologist for
Fulcrum to be able to report resources compliant with established
resource codes.
