Strong Initial Leaching
Results from Phase 1 Tailings Programme at Teck-Hughes
Gold
Extrakt's technology delivers
impressive initial gold recovery rates of up to
59.4%
Fulcrum Metals plc (LON: FMET), a
company focused on mineral exploration and development in Canada,
is pleased to announce strong initial leaching results from the
Phase 1 sampling and testing programme (the "Programme") using
Extrakt Processing Solutions LLC's ("Extrakt") non-toxic technology
at the Teck-Hughes gold tailings project in Ontario, Canada (the
"Project").
Highlights
·
A proportionate mixed composite sample of all six
sites grading 0.723g/t Au
was submitted for batch leach testing using Extrakt technology for
gold recovery rates (please see announcement dated 7 May
2024).
·
Preliminary leaching results from the
"as-received" composite sample (please see announcement dated 7 May
2024) achieves strong initial gold
recovery rates of up to 59.4%.
·
Optimisation of operational parameters are
underway to achieve targeted
recovery rates beyond 60% focussing on overall efficiency
and cost effectiveness.
Ryan Mee, Chief Executive Officer of Fulcrum,
commented:
"The success of every tailings project is dependent on the
efficiency and effectiveness of the technology used. I am thrilled
with the exceptional gold grades from our initial sampling and
testing programme which are 16.9% higher than the historical
reported average grade, and with Extrakt's non-toxic technology
achieving initial leaching gold recovery rates of over 59%. It is
important to note that no metallurgical studies have been completed
at Teck-Hughes before and that recovery rates from refractory gold
without cyanide or pre-treatment are usually below 40%, so to
achieve the recovery rates that we have on samples with no
pre-treatment or re-grinding is outstanding and hugely
encouraging.
"The work undertaken so far provides a compelling pathway to
transform mine tailings from an environmental liability into a
sustainable resource by extracting metals from mine waste through
innovative technology.
"I
look forward to providing further updates on the leaching test work
optimisation at Teck-Hughes and developing the exciting potential
of Fulcrum's tailings business in Ontario".
The
Phase 1 Programme summary
The Programme, which is designed to
evaluate the efficiency of Extrakt's processing technology in
recovering gold from the tailings at the Teck-Hughes Project, has
been very successful to date. Sampling and analysis of the gold
content of the tailings produced composite samples for each of the
six sites returning an average weighted grade of 0.717g/t Au which is 16.9% higher (please see announcement
dated 7 May 2024) than historic sampling of the same sites.
Initial leach tests using the
Extrakt Technology has reported gold recovery rates of up to
59.4%, using the as-received composite sample with no
re-grinding.
Further leach tests are underway to
optimise the operational parameters to achieve beyond 60% recovery
focussing on overall efficiency and cost effectiveness.
Licensing discussions with Extrakt
The Company announced on 30 November
2023 that, inter alia, it
had entered into a mining option agreement to acquire the Project.
Since this announcement, Fulcrum has been advancing its 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.
On 24 January 2024, Fulcrum entered into a phased study and testing
programme for the Project. The company is continuing term sheet
stage discussions in relation to a wider licencing framework in
Ontario.
The
Phased development programme outline
Phase 1 - sampling and testing
·
Sampling - complete across six
locations chosen to provide representative sampling across the
tailings with 32 samples (totalling 39kg). The 32 samples were
compiled into six individual site composite samples for
testing.
·
Grade and
composition testing - the six
composite samples were sent for ICP multielement analysis and gold
fire assay at the ISO-17025 accredited American Assay Laboratories
facility in Sparks, Nevada. Results returned an average weighted
gold grade of 0.717g/t Aum which is 16.9% higher (see RNS 7 May 2024) than
historic sampling at the same sites. Initial XRD
Semi-Quantitative Analysis of the six samples
reports primary tailings composition comprising quartz - felspar -
carbonate. Further detailed XRD analysis is to be carried
out.
·
Gold recovery
testing - a composite sample across
all six sites grading 0.723g/t Au was then submitted for batch
leach testing using Extrakt's technology for gold recovery rates.
The leach test samples were sent to ISO-17025 accredited American
Assay Laboratories facility in Sparks, Nevada for gold recovery
rates analysis. The initial leach tests have reported gold recovery
rates of 59.4%. Further leach tests are underway with further
refinement and optimisation which will then also be submitted to
American Assay Laboratories for the same analysis.
·
Next
steps - Further refinement of leach
tests with Extrakt Technology and final report on Phase 1 will be
provided. These results will then feed into the Phase 2 conceptual
study.
Phase 2 - Conceptual Study
The conceptual study will provide
Fulcrum with a first insight into the project 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 optimize 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 conducted at the Project, the first in 1980 and the
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 programme from 1980, an
estimate of the tonnage was calculated over the north, west and
northeast arm of the tailings totalling 6,531,300 tonnes of material at
0.66g/tonne Au for
138,460 ounces contained
Au. This estimate remains to be verified by Fulcrum.

Notes to Editors
FULCRUM METALS - BACKGROUND
Fulcrum Metals PLC (LON: FMET) is an
AIM quoted exploration and development company which finances and
manages exploration projects focused on Canada, widely recognised
as a top mining jurisdiction. Fulcrum's
ambition is to create an environmentally friendly and sustainable
tailings and mine waste business, driving mining change through
combining low discovery risk assets and jurisdictions with
transformative technology capable of near-term cash flow whilst
capitalising on a portfolio of highly prospective exploration
assets.
Creating an environmentally friendly and sustainable tailings
and mine waste business
Through the adoption of potentially
industry disruptive technologies to deliver near-term cash
producing assets. Fulcrum has acquired two gold tailings projects
via option agreements, the Teck-Hughes and Sylvanite gold tailings
projects, in the prolific Kirkland Lake gold camp, Ontario. The
projects are within 3km proximity of each other, with non-compliant
estimates of 138,460 ounces of gold and 67,051 ounces of gold
respectively, totalling 205,511 ounces, subject to verification by
Fulcrum. In addition, Fulcrum is working on delivering a licensing
framework in Ontario with Technology partners Extrakt Process
Solutions and alliance partners Bechtel Engineering.
Growth stage gold projects in Ontario
Fulcrum has two drill ready gold
projects in Ontario.
The Big Bear and Jackfish Schreiber
- Hemlo properties have a history of prospecting and localised
extraction since the late 19th century. However, coherent
property-level exploration programmes have been limited or absent,
particularly in recent times. The work completed by Fulcrum at Big
Bear has established a gold corridor of 3km in the
Schreiber-Pyramid area with high grade gold in rock samples of up
to 45g/t and historical grades of upto 233g/t, developing multiple
drill targets and prospects. This trend is open to the North, East
and South for further discovery. Fulcrum has also completed high
resolution geophysical surveys which now fully cover Big Bear,
identifying a further 5 high priority exploration targets for
follow-up investigation. Big Bear is reported to have the potential
to host a large, structurally controlled, stratabound-style banded
iron formation (BIF) gold prospect similar to the Musselwhite
deposit (McNicoll et al., 2016), in addition to an Archean
greenstone, orogenic-style lode gold prospect, extending past the
bounds of known historical mineral occurrences.
The Tully property is host to a NI
43-101 compliant resource of 107,000 ounces of gold with high
grades reported in 1997 drilling of up to 2,555.5g/t Au over 0.5
metres within a wider intersection of 322.02g/t over 5.7 metres and
2013 drilling by SGX demonstrating potential extension and depth
reporting 9.01g/t Au over 6.7 metres, and 8.0g/t Au over 6.5
metres. Tully is located 30 kilometres northeast of Timmins within
the world class Timmins-Porcupine gold camp that has produced over
70m Oz of gold to date. Tully is 2 kilometres southwest of the
1.2Moz Bradshaw Gold Project of Gowest Gold Ltd., currently in
development and within 30km of several multi-million ounce
historical deposits including the producing Hoyle Pond gold
deposit. Work undertaken by Fulcrum has identified several drill
target locations with the objective of extending the deposit along
strike and at depth.
Establish the prospectivity of its wider non-core Ontario and
Saskatchewan portfolio
Fulcrum has highly prospective base
metal projects in Ontario and Uranium projects in Saskatchewan for
which cost effective exploration methods will be utilised to
evaluate the projects with a view to securing potential joint
venture and/or acquisition interest.
Ontario Base Metals - Fulcrum
has developed a strong nickel target at Dog Lake in the
Michipicoten Greenstone Belt with several rock samples in excess of
1,000ppm Ni related to a mafic/ultramafic intrusives, a strong
copper exploration target at Carib Creek in the Winston Lake
Greenstone belt with soil sampling surveys returning several
strongly anomalous copper samples up to 737ppm whilst at Tocheri
Lake in the Dayohessarah Greenstone belt a Versatile Time Domain Electromagnetics
(VTEM) airborne geophysical survey
conducted over the southwest corner of the property identified a
weak electromagnetic conductor which may indicate buried
mineralisation in addition to several magnetic targets.
Saskatchewan Uranium - Fulcrum
has amassed a highly prospective uranium portfolio of over 59,000
hectares across the Charlot-Neely, Fontaine Lake, Snowbird and
South Pendleton claims. All of the projects are outside the
Athabasca basin along major structures, on trend with historic
mines and areas of significant M&A activity. Recent discoveries
such as the Arrow discovery (4.3m tonnes at 0.83% U308) and Triple
R discovery (2.7m tonnes at 1.94% U308) have proved the concept of
exploring along major structure outside the Athabasca Basin.
Historic records at Charlot-Neely include rock samples of up to
6.2% U308, trenching samples of up to 2.1% U308 and significant
electromagnetic conductors covering a 16km zone thought to be
prospective for uranium mineralisation. Work completed by Fulcrum
at Charlot-Neely and Fontaine Lake includes hyperspectral data
compilation identifying exploration targets and field work
resulting in discovery of high-grade uranium mineralisation of up
to 0.8% U308 and the discovery of new uranium and radioactive
trends.
Conclusion
Fulcrum's mining assets are a
combination of low discovery risk and high prospectivity in the
exploration phase, so Fulcrum stands to be able to add
significantly to the inherent value through exploration and
development success. Fulcrum will continually review opportunities
with potential and with a view to increasing shareholder value. It
is the Board's intention to deliver medium and long-term growth and
to establish the Group as a significant exploration and development
company.
