GLOBAL ENERGY METALS ANNOUNCES EXCEPTIONAL
COBALT AND COPPER RECOVERIES FROM METALLURGICAL
TEST WORK AT MILLENNIUM COBALT PROJECT IN
AUSTRALIA; COBALT RECOVERIES EXCEEDED 95%
Vancouver, BC / TheNewswire / November 6, 2018 / Global Energy
Metals Corporation TSXV:GEMC | OTCQB:GBLEF | FSE:5GE1
(“Global Energy Metals”, the “Company” and/or "GEMC") is pleased
to report exceptionally positive results from the initial metallurgical
program conducted over the northern quartzite zone of the
Millennium Cobalt Project (“Millennium”) in Mt. Isa, Queensland
Australia.
Mitchell Smith, President & CEO commented:
“Having achieved these excellent metallurgical results is remarkable
at this growth stage of project development. The 2018 drilling
program at Millennium confirmed previous exploration work further
demonstrating that this deposit has exceptional cobalt mineralisation
continuity over a significant area and is open along strike and at
depth, increasing the potential for resource expansion. Following our
highly anticipated outright acquisition of the project we look
forward to rapidly advancing the Millennium Cobalt project on all
fronts including further drilling and additional metallurgical studies
planned for 2019.”
Two composite samples were sourced from diamond drill core
(MIDD001-MIDD010) from a program conducted at Millennium during
the first phase exploration program w h i c h c o n t i n u e d f o r s e v e r a l
months over the first half of 2018. The drilling tested the northern
quartzite domain that contains the majority of the known resource at
Millennium.
Highlights of the metallurgical test work include:
•Production of separate cobalt (Co) and copper (Cu) rougher
concentrate streams is possible.
•High-grade composite peak rougher floatation test:
•Combined Cu recovery of 95.1%
•Combined Co recovery of 95.4%
•Au total recovery of 81.4% reporting dominantly to the Cu
concentrate
•Low-grade composite peak rougher floatation test:
•Combined Cu recovery of 91.3%
•Combined Co recovery of 91.7%
•Au total recovery of 77.9% reporting dominantly to the Cu
concentrate
•It is expected that the concentrate grades may increase on re-grind
and final cleaner floatation. This test-work will be conducted in
2019.
The results are considered very encouraging. Looking ahead, further
drilling is planned on both the northern and southern portion of the
Millennium deposit to expand and upgrade the current resource. This
will be accompanied by ongoing metallurgical characterization.
GEMC has entered into a binding agreement (the "Agreement") with
joint venture partner Hammer Metals ("Hammer") to acquire the
balance of the interest in the Millennium Cobalt Project as well as the
Mt. Dorothy Cobalt Project and the Cobalt Ridge Project (collectively
the “Mt. Isa Projects”), such that it will hold 100% of both Millennium
and the Mt. Isa Projects. This accelerated acquisition of cobalt rich
assets positions GEMC as the region’s leading cobalt explorer/
developer building a district-scale cobalt opportunity in Queensland
Australia’s Mt. Isa prolific mining jurisdiction.
First Stage Metallurgical Program:
Two composites were sourced from diamond drill core from a program
conducted during the first quarter of 2018 (refer to ASX releases
January 17th, June 5th and July 19th.) The drilling was testing what is
termed the northern quartzite domain at Millennium. This domain
hosts the majority of the Millennium Co-Cu-Au resource.
The test-work was done by ALS Metallurgy (“ALS”) in Adelaide. The
aims of the test-work were:
(1)determine Cu, Co and Au recoveries via rougher floatation;
(2)determine preliminary comminution parameters; and
(3) determine the main cobalt and copper minerals in concentrates.
Table 1 – Composite head grade assays (HG – high grade and LG – low
grade)
Twelve rougher float tests were undertaken on the high-grade and
low-grade composites. Each test was conducted using different grind
and reagent settings. The optimum settings were obtained in tests
HG-7 and LG-5 and the results of these tests are summarised below.
Quartzite is the main host lithology for this domain at Millennium and,
as expected, the comminution test work reported results are

indicative of a silica rich gangue material. The SMC test classified the
composites as “very hard”, abrasion tests as “slightly abrasive” and
the Ball Mill index test as “hard”.
Optical mineralogy and XRD analysis indicated that copper was
exclusively present as chalcopyrite (CuFeS2) and cobalt was identified
in both cobaltite (CoAsS) and catterite (CoS2).
