Clogau Operational Update

Alba Mineral Resources Plc (AIM: ALBA) is pleased to provide this operational report on the Company's Clogau-St David's Gold Project in Wales ("Clogau" or the "Project").

Level 5 Blasting

In the first phase of the blasting programme at Clogau, a total of 123 tonnes of ore was removed to surface, a combination of newly blasted ore and historic material left behind or deposited during previous mining periods.

Processing and Refining

Since the completion of the first phase of blasting, the focus has been on processing and refining. From the processing of 11.6 tonnes of newly blasted ore, 108.6 kg of concentrates have been sent to the Company's usual third party refiner and all these concentrates have now been refined, recovering 11.58 grams of gold. In that regard, it should be noted that the Level 5 blasting programme has not yet reached the proposed first incline raise (see Figure 1). Therefore, the blasted material to date does not represent the projected high-grade zone. The incline raises are designed to intersect the projected payshoot, thereby maximising the prospects of recovering economic grades and quantities of gold.

Figure 1: Section through Llechfraith showing the 5 Level development in relation to the projected pay shoot. Blasting has taken place at the Drive West and the Drive East. 4.5 Level drive is off-reef which means that Raise 1 can be commenced from closer to the current No.5 Level Drive West position.

As indicated in our last operational update, the Company has been making improvements to the Company's pilot processing plant to improve the efficiency and recovery of processing. The improvements have included:

- Repositioning of the wave table in front of the shaking table, involving the installation of a new concrete plinth for the wave table.

- Installation of a trommel to screen out oversize and enable a fine-grained delivery to the tables (Figure 2).

- Modifications to the hammer mill screens in order to limit oversize material.

Blasting Programme

Given the slower than anticipated progress of the first blasting programme, as outlined in our announcement of 11 December 2024, following a further review by our technical team it has been decided to reposition the first raise so as to be able to commence it much sooner in the planned blasting programme than previously planned (see Figure 1).  Raise 1 can be commenced within 5 metres from the current face position of the No.5 Level Drive West. This will result in an earlier transect across the projected payshoot. The raise will be developed at an angle of +50° so that it will be self-cleaning, eliminating the need for time-consuming mucking out.

Revised Work Programme

Alba's planned ongoing work programme can be summarised as follows:

· Firstly, complete the processing of the current surface stockpiles comprising the balance of the Waste Tip trenching material and No.5 Level blasted and historical material, totalling around 145 tonnes.

· Secondly, given the success of the Waste Pit sampling programme to date, where bulk grades of up to 3 g/t gold were defined, complete the Waste Pit trenching programme.

· Thirdly, resume the underground development programme on No.5 Level to complete the planned 1-2 incline raises.

Appointment of Chief Mining Engineer

The Company is very pleased to announce the appointment of Dr. Peter Bolt as Chief Mining Engineer for the Clogau Gold Mine. Peter Bolt is a highly experienced mining engineer, with a degree and PhD from Cardiff University. He worked for a decade at SRK (UK) Ltd, becoming Principal Mining Engineer. Between 2002-7 he worked as a director of AIM-quoted mining companies, including managing the underground development programme at the Quintana Gold Mine in Colombia. In 2007 Peter joined Continental Gold as VP Operations, responsible for their exploration and development projects in Colombia, including the Buritica, Machuca and El Limon mines. In recent years, Peter worked as an independent consultant on mining projects in Europe and Africa and was a consultant with WSP for 6 years. He has previously consulted to the Company in relation to the Clogau Gold Project.

George Frangeskides, Executive Chairman, commented:

"We are delighted to welcome Dr Peter Bolt to our team. Peter has a wealth of knowledge as a senior mining engineer, notably in relation to underground gold mines and processing operations, and we have already begun to see the benefits of that in terms of our formulation of a forward plan for Clogau.

"While the gold recovered to date from the processing and refining of the newly blasted material from No.5 Level is modest, the first phase of the blasting programme did not reach the proposed first incline raise and so the blasted material to date does not represent the projected high-grade zone within the Llechfraith Target, our primary gold target within Clogau. As such, the gold grades in that key zone remain to be ascertained."
