Wapouzé

Wapouzé (88 km²) is located 20 km north of Bibemi. Following a review of the historical data in 2022-2023, the Company determined that gold prospectivity at Wapouzé was lower than that at Bibemi project. However, it highlighted the potential for cement-quality limestone and so Oriole submitted a formal request for a change of substance at the Wapouzé licence area from gold to industrial minerals.

Oriole has rapidly advanced the Wapouzé project since 2025, having recently completed a maiden drilling programme, which has resulted in the definition of a maiden Mineral Resource in October 2026.

As of late-October 2026, Oriole has also submitted an Exploitation Licence Application (ELA) for a project that would likely comprise a multi-pit quarrying operation and a processing facility which together will produce a chemically and physically homogeneous crushed marble product.

Commercially, a significant limestone deposit at Wapouzé could support Cameroon’s cement industry, which is believed to be worth several hundred million pounds per year, and is largely dependent on expensive importation of essential clinker material.

Oriole is continuing its discussions with potential industry partners that could advance Wapouzé towards development and exploitation on an expedited basis. The Company is ultimately looking to achieve an income from a commercial scale quarrying operation, which would provide valuable in-country revenue that could be used additional funding for its gold exploration work in Cameroon.

Following the completion of the maiden drilling programme, a maiden Mineral Resource Estimate (MRE) was generated for the marble/limestone deposit by Forge International. The drilling enabled the definition of 6 marble domains (M1-6) of an Inferred Mineral Resource Estimate that stands at 32.2Mt with weighted average grades of 50.33wt% CaO, 1.13wt% MgO and 6.06wt% SiO₂. The marble domains were constrained by four open-pit RPEE pit shells (Pits 1-4), with Pit 1 (targeting M1 and M2) comprising approximately one third of the Resource, contributing 11Mt at an average grade of 52.68wt% CaO and 0.97wt% MgO.

Outside of the MRE, an Exploration Target was also defined, which stood at between 5.50 to 14.0Mt with average CaO grades between 48 and 53wt%, and MgO grades between 0.8 and 1.4wt%.

The presence of metamorphosed limestone (or marble) within the licence area was confirmed during the geological mapping of the north-eastern corner of the licence. Since the change in commodity in 2023, a total of 167 rock chip samples have been collected across the licence area, targeting limestone lithologies. Of these 167 samples, 21 returned elevated MgO (>5 wt%), and were therefore considered dolomitised, the remaining 146 all returned low MgO (< 5%wt), low SiO₂ (<1.5 wt%), and high-CaO (>50wt%), thus indicating the material was likely suitable for use in cement production.

A maiden diamond drilling programme was completed in July 2026 at 1,053.80m in 21 holes. The programme was designed to target the depth continuity of the in-situ limestone observed at surface, which were typically steeply dipping (60 – 80°) to the southeast. Holes were drilled at 320° azimuth and an inclination of -50° to depths of between 26.50 and 62.00m, targeting the shallow (<47.50m) vertical depth of the units. The intersected true width of the marble package is up to ~80m (based on drilling to date, apparent width of ~85m).

Best results include: 53.50m at an average of 53.88wt% CaO and 0.88wt% MgO from 1.30m depth in WPDD012, 37.15m at an average of 53.42wt% CaO and 0.82wt% MgO from 10.95m depth in WPDD014, 23.00m at an average of 53.90wt% CaO and 0.64wt% MgO from 1.30m depth in WPDD001, 20.05m at an average of 51.10wt% CaO and 1.16wt% MgO from 29.00m depth in WPDD015.

The majority of holes returned high-quality marble (>50wt% CaO and <2% MgO) over more than 50% of their length when considered as cumulative thicknesses.

In Q1-2021, the Company completed a 150m pilot trenching programme for three trenches (WPT001 to WPT003) across a small portion of the 8km-long anomaly. However, the programme did not return any significant intersections and so in Q4-2021, a further five trenches (WPT004 to WPT008) were completed for 2,524m. Four of the trenches were planned to test the anomaly either side of the pilot trenches, at a regional spacing of 500m to 1km, whilst the fifth trench was designed to test the centre of the parallel 2.8km-long anomaly. All trenches were orientated towards 130 degrees. The results reported today have confirmed anomalous gold (using a 0.10 g/t Au cut off) in all trenches, with a best intersection of 2.00m grading 4.06 g/t Au reported in WPT007.
