Sanu Gold Announces Additional Results from the Bantabaye Permit: 1.2 g/t Au over 40 m, Including 5.4 g/t Au over 4 m from Channel Sampling and 189.7 g/t Au from Rock Chip Sampling

Vancouver, September 12, 2023 - Sanu Gold Corp. (CSE: SANU) (OTCQB: SNGCF) ("Sanu Gold" or the "Company") is pleased to announce the results from further surface sampling at 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 km¹ south of the multi-million ounce Lefa Gold Mine and 80 km north of the multi-million ounce Bankan Gold Project.

Highlights

• 1.2 g/t Au¹ over 40 m¹, including 5.4 g/t Au over 4 m in channel BANT-TR-03 at Target 7,
• This channel sampled strongly sheared and hydrothermally altered felsic volcanics and returned gold mineralization over its entire 40 m length, with individual samples returning up to 12.3 g/t Au over 1 m,
• This channel is located within the central part of Target 7, where initial drilling intersected gold mineralization along a 500 m long section of the Tinkisso Fault,
• Rock chip samples collected in proximity to this channel returned grades of up to 189.7 g/t Au.

Martin Pawlitschek, President and CEO, commented: "We continue to see good gold grades over broad widths from channel sampling across Bantabaye's Target 7. Within the 700 m long Target 7 to Target 3 corridor, we see a zone of strongly altered and mineralized volcanics that has been a focus for intense artisanal mining. The ongoing mining of visible gold from this area, combined with results from initial drilling, channel sampling and rock chip sampling, demonstrate the prospectivity of the shear-hosted gold system at Bantabaye."

Target 7
Channel BANT-TR-03 sampled a 40 m long exposure of saprolitized bedrock at 1 m intervals from new exposures at Target 7 created by the construction of drill roads and pads (Figure 1 and Table 1). The objective of this sampling was to further test the mineralized felsic intrusive intersected by the first phase of reverse circulation ("RC") drilling (see the Sanu Gold news release dated July 27, 2023). This northwest trending channel contains highly sheared, strongly hydrothermally altered and locally brecciated felsic intrusive with quartz veinlet stockworks and boxwork after sulphide. All samples from the channel returned gold values above detection limit, with 11 of 40 samples returning grades above 1.0 g/t Au, including 12.3 g/t Au over 1 m, 4.7 g/t Au over 1 m and 3.6 g/t Au over 1 m, as well as 2.8 g/t Au over 1 m from the sample collected at the westernmost end of the trench.

Channel BANT-TR-03 is located 15 m southeast of trench BANT-TR-01, which returned 1.1 g/t Au over 43 m, including 4.2 g/t Au over 6 m (see the Sanu Gold news release dated Sept. 6, 2023).

An additional 5 rock chip grab samples were collected from saprolitized felsic intrusive rock at Target 7 in proximity to BANT-TR-03 and returned values of up to 189.7 g/t Au (Figure 1 and Table 2). These samples were comprised of highly sheared, hydrothermally altered and locally brecciated felsic intrusive with stringers of quartz veinlets and boxwork after sulphide.

Gold mineralization at Target 7 is associated with a northwest striking and shallowly southwest dipping felsic intrusive that extends for over 500 m along strike and 150 m in width. As previously announced, the Company has drilled a total of 1,603 m in 14 RC holes at Target 7. Highlights from this drilling included:

• 0.91 g/t Au over 9 m, including 1.55 g/t Au over 1 m and 2.11 g/t Au over 2 m (BANT-RC-23), and
• 0.87 g/t Au over 13 m, including 1.65 g/t Au over 3 m and further downhole 3.47 g/t Au over 1 m (BANT-RC-22)².

Target 7 is located within a 700 m long area extensively worked by small-scale artisanal miners. Drilling to date at this target has not intersected the high-grade mineralization exploited by artisanal miners and it is interpreted that the relatively shallow drilling completed to date has been exclusively within areas where the high-grade mineralization has been mined out.

Results from BANT-TR-01, BANT-TR-03 and rock chip samples, combined with initial drill results from Target 7 confirm the presence of an extensive gold mineralized corridor associated with altered and deformed felsic intrusive rock. Mineralization is open in all directions and ongoing work is focused on delineating targets for the next phase of drilling at Bantabaye.

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. All samples were analyzed using Fire Assay (FA505) at the SGS Laboratory in Bamako, Mali ("SGS"). SGS is an internationally recognized and commercially certified laboratory and is independent of Sanu Gold.
