gold), XRD mineralogical analysis and batch leach
testing
o Duplicate phase 1 and additional tailings samples (announced
by the Company on 2 September 2024) are now at Actlabs in Timmins
for gold fire assay
· Fulcrum management are scheduled to meet with key stakeholders
of the tailing projects in Ontario including on-site visits to
Teck-Hughes and Sylvanite in October
Ryan Mee, Chief Executive Office of Fulcrum,
commented:
"There are strong workstreams now underway at our tailings
projects which are designed to build on the exciting initial
leaching results already achieved at Teck-Hughes with Extrakt's
non-toxic technology and how the gold is extracted. The leaching
test work results of 59.4% gold recovery far exceeded past
cyanide-based leaching tests at Sylvanite of c.30% so we are
excited to move into test work at Sylvanite and on to the
conceptual study at Teck Hughes. In addition to this, we are moving
forward with work directed towards resource definition including
additional auger hole sampling and geophysical surveys at Teck
Hughes. These are all important objectives as part of Fulcrum's
ambition to become a leader in the sustainable reprocessing of
tailings through the adoption of disruptive technology and
approaches.
"Our site visits and meetings in October are an important step
as we look to build momentum on the development of the tailing
projects in Kirkland Lake and I look forward to providing further
updates as Fulcrum moves to accelerate the development of its
tailings projects and the wider tailings opportunity in
Ontario."
Teck-Hughes Tailings
Project
At Teck-Hughes, the Company has
engaged a local contractor to complete auger hole sampling across a
proposed additional 16 sites (Figure 1 below) during the next few
weeks. It is anticipated that this will provide important data on
gold grades and depth to assist the Company as it looks to achieve
a resource definition. Samples obtained from this program will be
sent to Actlabs in Timmins for gold, and possibly silver and
tellurium, assay.

Discussions are also underway with
geophysical survey providers on the application of certain
geophysical surveys including LiDAR, ground-penetrating radar and
seismic line. The aim of these surveys is to define the outline and
depth of tailings across the Teck-Hughes deposit in order to enable
volume estimations.
Fulcrum has received a proposal
from, and is in discussions with, Extrakt regarding a Phase 2
conceptual plant design at Teck-Hughes. This is being advanced
alongside discussions with Extrakt on the exclusive licensing of
its non-toxic leaching technology across the Timmins and Kirkland
Lake areas. These areas have historically produced more than 110
million ounces of gold and there are a number of legacy tailings
sites which the Company believes could enable it to scale
operations.
Sylvanite Tailings
Project
Earlier this year a total of 30
samples were taken from eight locations at Sylvanite providing
representative sampling across the tailings deposit. The samples
were split in to two equal sample sets. One half of the samples
were sent to 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.
The second half of the samples is
now with Actlabs in Timmins for gold assay which will provide
additional grade verification from testing laboratories more local
to Fulcrum's projects. Results of these tests are anticipated at
the end of October 2024 and the Company will inform the market of
the results once they have been analysed.
An additional four auger holes at
each of Teck-Hughes and Sylvanite were completed in August 2024 and
samples from these have also been sent to Actlabs in Timmins for
similar assay, with results expected in a similar
timeframe.
Fulcrum's management is scheduled to
be on site at Teck-Hughes and Sylvanite in October and will be
undertaking a number of meetings with key stakeholders including
sub-contractors, potential in-country management and consultants,
potential collaborative partners and local communities. The Company
believes that this engagement is incredibly important as it embarks
on accelerating the program of development across its tailings
projects.
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
recent 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 totaled 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
totaling 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 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 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.
