SANU GOLD TO COMMENCE 10,000-METER DRILL PROGRAMME AT DAINA AND BANTABAYE; Q1 AUGER AND IP PROGRAMS DEFINE NEW TARGETS AT DIGUIFARA

Sanu Gold Corp. has provided a corporate update on its Guinean properties, including preparations for a 5,000-metre aircore/reverse circulation drilling program at its Daina property. In addition, the company is well advanced with access preparations for a 5,000-metre AC/RC drilling program and a 3,000-metre auger sampling program at the Bantabaye property, targeting an eight-kilometre structural corridor. Recent auger results from the Diguifara property have defined a two-kilometre gold-bearing structure, which is under evaluation for follow-up drilling.

Highlights

Daina:

• Expanded footprint at Daina, with recently added auger results defining up to 8.4 kilometres (Daina 1), 3.6 km (Daina 2) and three km (Daina 3) of mineralized trends for drill testing in 2026;
• Anomalous gold results with auger intercepts up to six m at 2.31 grams per tonne gold and rock chips up to 34.91 g/t Au, supported by historic workings and induced polarization trends suggesting structural continuity;
• Preparations for a 5,000-metre RC and AC drill testing program under way.

Bantabaye:

• First ever drilling campaign of 5,000 m; targeting an approximately eight-kilometre structural corridor at Bantabaye South (targets 9 and 10);
• Approximately 3,000 m of auger drilling at Bantabaye North to refine targeting along the four-kilometre Bantabaye thrust system, hosting targets 2, 3 and 7 and adjacent target 5.

Diguifara:

• First quarter 2026: 4,900-metre auger drilling program completed at Diguifara defined new targets in saprolite at targets 5 and 6 located in the northern part of the permit;
• Ground geophysics survey completed at targets 5 and 6.

Martin Pawlitschek, president and chief executive officer of Sanu Gold, commented: "Sanu Gold is pleased to be mobilizing AC/RC drill rigs to Daina and Bantabaye, where up to 5,000 m of target drilling will be completed on each project. At Bantabaye, targets 9 and 10, located along an eight-kilometre structural corridor at Bantabaye South, represent a potential extension beyond the initial drilling at Bantabaye North. Similarly at Daina, the largely untested and newly defined extensions and parallel structures at Daina 1, Daina 2 Northeast and Daina 3 could expand the currently defined mineralized trends. In addition, recent work at Diguifara has identified additional targets and highlights additional exploration opportunities across the portfolio. Sanu is well positioned and fully funded to advance these targets at Daina, Bantabaye and Diguifara."

Daina property

Previous exploration at the Daina gold property has defined multiple gold-bearing structures associated with northeast- and northwest-trending structural zones. Work completed since 2022 includes auger sampling, mapping, IP geophysics, trenching, and RC, aircore and oriented diamond core drilling across priority targets.

Recent programs, including a power auger saprolite sampling campaign for a total of 12.9 kilometres drilled and IP geophysics, have extended mineralization and firmed up additional strike lengths of mineralization of 8.4 km at Daina 1, 3.6 km at Daina 2 and 3.0 km at Daina 3, which remain untested by RC or AC drilling. Access track and drill pad preparations are under way for up to 5,000 m of RC and AC drill testing across these new targets and extensions. See press release dated March 31, 2026.

Bantabaye property

Bantabaye South

Targets 9 and 10

Previous termite mound, soil and auger sampling, and IP geophysics define priority targets 9 and 10 at Bantabaye South. Results highlight prominent and structured northeast-trending gold anomalies within the structural corridor of the southern portion of the Bantabaye thrust fault and associated secondary order parallel faults. The gold trend extends over approximately eight km. Results of termite mound, soil and auger sampling, and IP surveys provide good resolution of the surface gold footprint of targets 9 and 10.

Anomalous gold results were obtained from rock chip sampling in shallow, laterite-hosted historic mining areas adjacent to target 10, including 48.2 g/t, 7.58 g/t and five g/t Au. Historic mining occurs at the intersection between a prominent north-south-trending fault and a second-order northeast-trending fault. Interpretation of the chargeability and resistivity features identified structures that align with termite mound and auger gold geochemistry trends. These interpreted structural features, and the gold anomalies occur along an eight-kilometre corridor and remain untested.

The planned AC/RC program at targets 9 and 10 will drill test the interpreted mineralized structure across up to four fences at target 9 and three fences at target 10. Drill fences are oriented east-west for a total of up to 5,000 m of drill testing with AC and RC.

Bantabaye North 2026 auger sampling program

Bantabaye thrust corridor

This structure trends for over four km of strike within the permit, and is marked by historic workings, well-defined surface gold anomalies, IP geophysics trends and mineralization intercepted along targets 2, 3 and 7 by previous RC drilling and trenching.

Sanu previously delineated a gold mineralized structure at target 2 that extend over 500 m along strike, with previously reported drill returning intercepts including:

• 15 m at 11.4 g/t Au, including four m at 41.2 g/t Au in BANT-RC-002;
• 12 m at 2.0 g/t Au, including one m at 6.8 g/t Au and one m at 5.0 g/t Au in BANT-RC-003;
• 14 m at 1.94 g/t Au, including one m at 29.89 g/t Au in BANT-RC-048;
• 14 m at 1.50 g/t Au, including one m at 8.12 g/t Au and two m of 2.5 g/t Au in BANT-RC-031;
• 12 m at 1.00 g/t Au, including two m at 3.98 g/t Au in BANT-RC-033;
• 11 m at 1.20 g/t Au, including four m at 2.89 g/t Au in BANT-RC-035;
• Three m at 9.86 g/t Au, including one m at 26.35 g/t Au in BANT-RC-036.

Gold mineralization has to date been intercepted over a 500-metre strike length at target 2 and to a vertical depth of up to 120 m, and remains open along strike and downdip. The entire four-kilometre strike length of the mineralized corridor at Bantabaye North is defined by geophysics, surface gold geochemistry, drilling results and historic workings extending from the western permit boundary though targets 2, 3 and 7.

Additionally, trenching at target 7 has returned wide intervals of gold mineralization in saprolite:

• 80 m at 1.6 g/t Au;
• 40 m at 1.2 g/t Au.

Thus far, systematic RC and oriented diamond core drilling has to date been limited to target 2 while limited reconnaissance RC drilling has taken place at targets 3 and 7, leaving the majority of the four-kilometre corridor untested. A 3,000-metre program of systematic power auger drilling is currently under way to sample the saprolite below the overburden laterite along the so far undrilled parts of the entire four-kilometre trend. The aim is to highlight higher-grade segments of the structure for future deeper RC and AC drill testing.

Target 5 (Bantabaye North)

Target 5 is located north of the Bantabaye thrust fault zone at Bantabaye North and is located along an interpreted northeast-trending structure, linked to targets 3 and 7. The target area is characterized by strong termite mound gold anomalies, a thick soil profile and a lack of outcrops. Auger lines allow systematic sampling of the saprolite underneath the soils to map any underlying bedrock mineralization for future RC drill testing.

Diguifara property

Auger sampling (targets 5 and 6)

During first quarter, Sanu completed additional auger sampling on the northern part of its Diguifara gold project with two power auger drilling rigs operating over day and night shift. The auger sampling program was designed to follow up gold anomalies from previous soil and termite mounds geochemistry in the northern part of the permit. The results of this program established the presence of significant gold-bearing structures in the saprolite below the overburden, and these are currently under evaluation for future RC and AC drill testing.

Sanu completed drilling in 432 auger holes. The sampling program covered a strike length of five km at target 5 and three km at target 6. Auger lines are east west oriented and spaced 200 m apart with sampling holes spaced 50 m along the lines. Samples were composited over two m with a total of 2,683 samples (including control samples) sent to the MSA laboratory in Bamako (Mali) for gold analysis. The holes were planned to a minimum depth of 10 m, but, due to the thickness of the duricrust, the average drill depth was 12.4 m per hole.

Results of the auger sampling at targets 5 and 6 are encouraging, outlining a corridor of two km of gold in saprolite anomalies at targets 5 and 6. The anomalies are defined at greater than 100 parts per billion gold in saprolite with best auger gold intervals in saprolite of eight m at 2.23 g/t, eight m at 1.74 g/t and eight m at 0.61 g/t Au. The gold mineralization is associated with volcanoclastic rocks cut by numerous quartz veins and stockwork of white or smoky quartz.

IP survey at target 5 and 6

A ground geophysical survey program was recently completed in the northern part of the permit over targets 5 and 6. The survey comprised a total of 106 line kilometres of gradient array induced polarization geophysics. The survey consisted of 25 east-west-oriented and 200-metre-spaced lines that varied from 2.6 km to 3.9 km in length. The data were collected, processed and interpreted by Sagax Afrique of Ouagadougou, Burkina Faso, using the induced polarization/resistivity method.

The objective of this ground geophysical survey program was the detection and description of geophysical features (chargeability and resistivity) that can help identify bedrock structures trends that might be associated with gold mineralization and to guide follow up RC or AC drill testing.

Interpretation of the IP survey results indicate the occurrence of well-defined geophysical trends parallel to known geology and structures from the detailed ground mapping and regional maps. Furthermore, structural interpretation of the geophysics features aligns with termite mound and auger gold geochemistry trends. These interpreted structural features and the gold anomalies remain to date untested.
