Sanu Gold Announces Positive Cyanide Leach Test Results at the Bantabaye Permit in Guinea, West Africa: 92 to 93% Average Gold Recovery
Sanu Gold Announces Positive Cyanide Leach
Test Results at the Bantabaye Permit in
Guinea, West Africa: 92 to 93% Average Gold
Recovery
Vancouver, British Columbia--(Newsfile Corp. - November 16, 2023) -
Sanu Gold Corporation (CSE:
SANU) (OTCQB: SNGCF)
("Sanu Gold" or the "Company") is pleased to announce positive initial
cyanide leach test results from the Company's flagship Bantabaye gold exploration permit ("Bantabaye"
or the "Permit") in Guinea, West Africa. The Permit, which lies on the western margin of Guinea's prolific
Siguiri Basin, is located approximately 50 kilometres ("km") south of the multi-million ounce Lefa Gold
Mine and 80 km north of the multi-million ounce Bankan Gold Project.
Highlights:
Initial cyanide leach test work (the "Test Work") was undertaken on representative samples from
the main mineralized rock types drilled in the Company's inaugural H1/2023 drill program,
The Test Work returned average gold recoveries of 92 to 93%
from the three rock types
tested, including:
93% average recovery from unoxidized mafic rock
(range: 91 to 96%),
92% average recovery from unoxidized felsic rock
(range: 84 to 95%),
92% average recovery from oxidized felsic rock
(range: 86 to 97%; Table 1),
Results demonstrate highly favorable gold recoveries may be achieved with cyanide
leaching.
Martin Pawlitschek, President and CEO commented: "At our flagship project in Guinea, West Africa,
initial cyanide leach test work from the three main mineralized rock types drilled in the Company's
inaugural H1/2023 drill program has returned very encouraging results, highlighting the potential for good
gold recoveries by conventional crush-grind-cyanide leaching processes at Bantabaye. Oxidized and
fresh rock types from the main mineralized zones drilled to date have returned average gold recoveries
of 92 to 93%, which compares favorably with gold mining operations and projects in the region. As
drilling progresses more detailed metallurgical studies will be undertaken, focusing on further
characterization of the different mineralized rock types and optimization of potential recoveries."
Program Summary
The primary objective of the Test Work was to assess potential gold recovery by cyanide leaching for
gold mineralization discovered to date at Bantabaye. Material for testing was collected from reverse
circulation ("RC") drill chip rejects from the Company's H1/2023 Phase 1 RC drill program at Bantabaye,
which consisted of 3,198 metres ("m") drilled in 28 RC drill holes. Results from the Phase 1 RC drill
program included
11.4 g/t Au
1
over 15 m, including 41.2 g/t Au over 4 m
(BANT-RC-002).
A total of 101 samples encompassing a wide range of gold grades, downhole depths, lithology and
intensity of weathering/oxidation state in the three main mineralized rock types drilled were analyzed.
Test Work procedures are summarized below.
Table 1 summarizes the grades and recoveries for each of the three mineralized rock types tested.
Results from the Test Work indicate comparable recoveries from oxidized and unoxidized material, as
well as from felsic and mafic host rock. No direct correlation was observed between gold grade and
recovery.

Next Steps
Future metallurgical test work is planned to include grindability and bottle roll testing, to provide an initial
indication on crushing and milling power requirements, gold leaching kinetics, and key reagent
consumptions.
Test Work Procedures
Samples were submitted to the SGS Laboratory in Bamako, Mail ("SGS Mali") and analyzed for Fire
Assay FAA505 and subsequently shipped to the SGS Laboratory in Ouagadougou, Burkina Faso
("SGS Burkina Faso") for LeachWell (LWL69M) analysis on 2-kilogram splits and Fire Assay FAA505
on the tails to determine gold recovery. Leachwell tests were undertaken at a grind size of 80% - 75
microns ("µm") and Individual mineralized samples were gently agitated in a leaching solution for up to
12 hours.
Both SGS Mali and SGS Burkina Faso are internationally recognized and commercially certified
laboratories and are independent of Sanu Gold.
Quality Assurance / Quality Control ("QA/QC")
Sampling was completed following industry best practices, conducted under the supervision of the
Company's project geologists and the chain of custody from the project to the sample preparation facility
was continuously monitored. An appropriate number and type of certified reference materials
(standards) and blanks totaling 5% of the total number of samples shipped to the laboratory was inserted
approximately every 20th sample to ensure an effective QA/QC program was carried out. Data
verification of the analytical results included a statistical analysis of the standards and blanks that must
pass certain parameters for acceptance to ensure accurate and verifiable results.

About Sanu Gold
Sanu Gold is a publicly traded exploration company focused on a portfolio of highly prospective gold
projects in Guinea, West Africa's Siguiri Basin.
West Africa is the number one gold mining region in the world and Guinea's Siguiri Basin is a prolific, yet
underexplored part of this region. Despite being home to both long-lived multi-million ounce gold mines
and recently commissioned gold mines, Guinea's Siguiri Basin continues to produce important new gold
discoveries.
Sanu Gold has defined multi-kilometer long gold-bearing structures on each of its three exploration
permits and is targeting near-surface multi-million ounce gold discoveries. Initial drill programs on the
first two permits drilled have yielded high-grade gold discoveries. The company is operated by a highly
experienced team, with successful records of discovery, resource development and mine permitting
across West Africa.
