Sanu Gold Reports That Drilling Has Defined a

Broad Mineralized Corridor at Its Daina

Property in the Siguiri Basin in Guinea

HIGHLIGHTS

Sanu drilled 17,802m in FY-2025 mainly focused on its highly attractive Daina property.

At the Daina property,

12,896m were completed in FY-2025, with results continuing to reveal

significant near-surface and deeper gold mineralized zones extending over multiple kilometres and

remaining open

Daina 2 Target:

Step out Air Core ("AC") drilling to the south along the identified

geophysics trend has

expanded

the trend to over 4km, with best intercepts including:

16m at 1.81 g/t Au from 44m, including 2m at 12.24 g/t Au from 48m

12m at 1.71 g/t Au from 12m, including 2m at 3.90 g/t Au from 20m

12m at 1.32 g/t Au from 54m, including 4m at 3.02 g/t Au from 62m

6m at 1.26 g/t Au from 36m, including 2m at 3.23 g/t Au

Salat East Target:

Reverse Circulation ("RC") drilling and Diamond Drilling ("DD") targeted

the down dip extension of the granodiorite hosted structure, with significant intercepts

including:

21m at 1.02 g/t Au from 17m, including 5m at 1.80 g/t Au & 3m at 1.92 g/t Au

20m at 0.66 g/t Au from 175m, including 1m at 15.41 g/t Au from 281m

Daina 1 South Target:

Follow up RC and AC drilling over an extensively interpreted

geophysical trend, with best intercepts including:

9m at 1.22 g/t Au from 175m, including 1m at 9.56 g/t Au

24m at 0.72 g/t Au from 34m, including 1m at 7.03 g/t Au

10m at 0.83 g/t Au from 46m, including 1m at 1.92 g/t Au

At the Bantabaye property,

601m of DD drilling were completed in FY-2025 on the at Target 2

along soil, auger, and IP results from the southern part of the permit confirming the presence of

large structural trends with strong gold anomalies, while high-grade artisanal zones are drill-ready

for further testing.

At the Diguifara property

, 4,305m of drilling were completed in FY-2025 across Targets 1, 2 and

3 identifying wide mineralized zones which have been intersected along multiple fault-controlled

targets, demonstrating a robust and extensive gold system.

Sanu Gold is well funded to continue advancing exploration activities in FY-2026 with a strong

continued focus on its Daina property, given its current cash and cash equivalents position of

approx. CAD 22 million.

Vancouver, British Columbia--(Newsfile Corp. - December 11, 2025) -

Sanu Gold Corporation

(CSE:

SANU) (OTCQB: SNGCF)

Sanu

Gold

" or the "

Company

") is pleased to announce drill results from

its continued exploration program across its three exploration permits located in the prolific gold

producing Siguiri Basin of Guinea, West Africa.

Martin Pawlitschek, President and CEO of Sanu Gold

commented:

"These latest results further

confirm the strength and potential scale of the Daina gold system, underscoring its geological

similarities to other well-established deposits in the district. The consistent intersections of significant

gold mineralization across multiple targets—particularly at Daina 2, Daina 1 South and Salat East—

continue to expand the footprint of this emerging mineralized trend. With mineralization remaining

open along strike and at depth, and with both shallow oxide and deeper structurally controlled zones

now well established, Daina presents an increasingly compelling opportunity for systematic follow-up

and infill drilling beginning in Q1-2026.

We are also very encouraged by the ongoing progress at Bantabaye and Diguifara, where recent

drilling, sampling and geophysical programs continue to outline broad gold-bearing structures with

strong continuity and highly prospective grades. With the Company now fully funded to continue

advancing and de-risking its exploration portfolio through FY-2026, we are excited to further explore

and unlock the significant potential across our district-scale land package in the Siguiri Basin."

As shown in Table 1 below, the majority of the FY-2025 exploration efforts have focused on the Daina

property and were conducted between January and late August. All assays have now been received and

are informing the next drilling programme set to begin in early 2026. In the meantime, fieldwork and

drilling preparations are currently underway.

At the Daina property, drilling has expanded both near-surface oxide and deeper structurally controlled

gold mineralized zones over multiple kilometres, with all key targets remaining open for further growth. At

Bantabaye, diamond drilling at Bantabaye 2 Target and continued soil, auger and IP work in the southern

portion of the permit are defining broad structural corridors with strong gold anomalies, while high-grade

historical workings are advancing toward targeted drill testing. While at Diguifara, drilling across several

fault-controlled targets continues to return wide mineralized intervals, confirming a robust and extensive

gold system.

Given the current cash and cash equivalents position of approximately CAD 22 million, Sanu Gold is well

funded to continue advancing exploration activities in FY-2026, with a continued strong focus on the

Daina property.

DAINA PROPERTY

Daina is the Company's most advanced property, with ongoing drilling continuing to outline a large, multi-

kilometre gold system across several closely spaced targets. Gold mineralization consistently

intercepted at shallow depths and within deeper structural zones that remain wide open for expansion.

The latest results have further strengthened the continuity of mineralization at Daina 2, Daina 1 South and

Salat East, demonstrating well-defined structural controls and highlighting the potential for higher-grade

shoots within a broader mineralized corridor. Multiple targets only partially drilled and several additional

areas yet to be tested, Daina continues to present considerable upside opportunity as systematic

exploration advances. Full set of results for all new drill intercepts are provided in Appendix 1.

As shown in Figure 1, a total 12,896 metres have been drilled at the Daina targets in FY-2025. This work

was completed across 164 holes, including 109 AC holes totalling 5,541 metres, 46 RC holes totalling

5,180 metres, and 9 DD holes totalling 2,175 metres. The ongoing drill program remains focused on

evaluating the lateral and downdip extensions of the gold-bearing structures previously identified at

Daina 2, Daina 1 South, and Salat East.

Daina 2 Main Target

At the Daina 2 Main Target, diamond drilling has extended known mineralization to a vertical depth of

approximately 245 metres and provided important geological and structural data to guide future

targeting. Mineralized zones ranging from 5 to 50 metres in width now defined along more than 4-

kilometres of a north-northwest-trending structure that remains open along strike and at depth, with

several untested gaps offering clear opportunities for further expansion. As shown in Figure 2, recent

drilling has continued to trace the mineralized trend to the south, confirming the continuity of the Daina 2

structure. Several significant new intercepts were returned, including intervals ending in End-of-Hole

("EOH"), highlighting the potential for additional mineralization at depth.

DAI-AC-130:

16m of 1.81 g/t Au (EOH) from 44m, including: 2m of 12.24 g/t Au from 48m

DAI-AC-116:

12m of 1.71 g/t Au from 12m, including: 2m of 3.9 g/t Au from 20m

DAI-AC-136:

6m of 1.26 g/t Au (EOH) from 36m, including: 2m of 3.23 g/t Au from 38m

DAI-RC-090:

12m of 1.32 g/t Au from 54m, including: 4m of 3.02 g/t Au from 62m

Lithologies consist of sedimentary rocks composed of turbidites sequences of alternating layers of

sandstone, siltstone and shale and mineralized zones consisting of a deformed and altered greywacke

layer immediately in the hanging wall of the shear zone. Mineralization consists of quartz and quartz-

carbonate veinlets, fine disseminated pyrite and rare arsenopyrite. The style of mineralization is typical

to what is described from other deposits in the district.

Structural measurements on oriented diamond core demonstrate the main structure controlling the gold

mineralization is a north northwest-striking reverse brittle-ductile shear zone, moderately dipping

southwest. These measurements are consistent with previous structural interpretations obtained from

outcrops and exposed rocks from historical workings. The footwall side of the shear zone is occupied by

a sequence of black shale.

Daina 1 South Target

At the Daina 1 South Target, diamond, RC and AC drilling has further tested the southern depth

extensions of the Daina Property to a vertical depth of 200 meters with variable widths ranging from 50

meters to 200 meters. The Daina 1 South Target is defined as a 1.3-kilometre north-northwest trending

structure which remains open for significant expansion along strike and at depth.

As shown in Figure 3 below, the drill program has followed the strike of the Daina deposit to the south to

continue to define the structure, with significant new interceptions shown below:

DAI-DD-004:

9m of 1.22 g/t Au from 175m including: 1m of 9.56 g/t Au from 175m

DAI-AC-092:

24m of 0.72 g/t Au from 34m including: 1m of 7.03 g/t Au from 44m

DAI-RC-089:

50m of 0.31 g/t Au from 28m including: 1m of 1.21 g/t Au from 28m

DAI-AC-093:

22m of 0.40 g/t Au from 18m including: 1m of 1.21 g/t Au from 28m

DAI-AC-094:

10m of 0.83 g/t Au from 46m, including: 1m of 1.92 g/t Au from 52m

The gold structure at the Daina 1 South Target forms multiple parallel mineralized structures, partly

exposed in large and active historical workings. Oriented diamond core shows the gold structures are

hosted in a hydrothermally altered greywacke unit. Structural measurements revealed multiple northwest-

striking moderately northeast-dipping brittle-ductile sheared zone systems at the contact between the

greywacke in the hanging wall of the fault and a high chargeability graphitic siltstone layer in the footwall.

The host greywacke is crosscut by a system of steeply dipping and highly mineralized quartz carbonate

veins and stockworks that host the gold mineralization.

Salat East Target

At the Salat East Target, diamond drilling tested a 500-meter segment of north-northeast striking, gold-

bearing structures hosted in a hydrothermally altered and sheared granodiorite. Mineralized zones have

been identified from surface to a depth of at least 150 meters with widths varying between 50 meters to

100 meters, remaining open along strike and at depth, and near one of AngloGold Ashanti's mining

permit.

The intrusive at the Salat East Target is cut by a north northeast-striking and moderately northwest

dipping gold-bearing shear. The host granodiorite is extensively sheared and hydrothermally altered; it is

associated with a zone of elevated chargeability and resistivity and coincides with a well-defined line of

surface artisanal workings. Gold mineralization at the Salat East Target is controlled by a network of

steeply dipping cm-scale and closely spaced quartz carbonate veins and veinlets associated with

disseminated pyrite and fine-grained arsenopyrites within the altered and sheared granodiorites.

As shown in Figure 4 below, new drilling results have followed the strike of the Salat structure, with

significant new intercepts shown below:

DAI-RC-095:

21m of 1.02 g/t Au from 17m, including: 5m of 1.80 g/t Au from 20m, 3m of 1.92 g/t

Au from 29m

DAI-DD-005:

20m of 0.66 g/t Au from 175m, including: 1m of 1.18 g/t Au from 181m, 1m of 1.42

g/t Au from 186m, 1m of 1.56 g/t Au from 190m, 1m of 1.87 g/t Au from 194m, and 1m of 15.41 g/t

Au from 281m

Daina Next Steps

Follow-up work has already begun at Daina to refine targets ahead of the 2026 drill program, which is

set to resume in Q1-2026, and expected to focus on expanding the extensive shallow and deeper gold

zones discovered to date:

At Daina 2 Target, infill AC and RC drilling is planned on the remaining gaps of the defined

structure.

At Salat East Target, an IP Survey is planned to follow the identified strike to the northwest where it

remains open, followed by further RC and AC drilling

At Daina 1 Target, an IP Survey is planned over the 9km gap between Daina 1 South and Daina 1

North followed by further RC and AC drilling

A program of additional target definition consisting of IP survey lines and auger sampling lines

followed by AC and RC drill lines is planned for a series of surface gold anomalies that so far

remain untested.

BANTABAYE PROPERTY

At the Bantabaye property encouraging drill results are emerging from both the northern and southern

parts of the permit. At the Bantabaye 2 Target in the north, oriented diamond drilling has confirmed that

the gold-bearing structure extends to depth and remains open, adding confidence that the system has

meaningful scale potential, given its 4-kilometre overall strike length that has so far only been partially

drill tested. In the south, a combination of soil and auger sampling, rock-chip results from active artisanal

workings, and 93 kilometres of IP geophysics have outlined multiple well-structured gold anomalies

extending over more than 8 kilometres of strike, defining new high-priority drill targets. Full set of results

for all new drill intercepts are provided in Appendix 1.

Bantabaye 2 Target

At the Bantabaye 2 Target, the drill program prioritized depth extensions of previously intercepted near

surface gold mineralization. A total of 601 meters has been drilled on the Bantabaye 2 Target in FY-

2025, completed across three DD holes. As shown in Figure 5 below, new drilling results continue to

define the depth of the structure, with significant new intercepts shown below:

BANT-DD-001:

4m of 3.00 g/t Au from 169m, including: 1m of 8.12 g/t Au from 170m

BANT-DD-003:

14m of 0.87 g/t Au from 62m, including: 4m of 2.39 g/t Au from 64m
